[0034] The following is a further detailed description of the preferred embodiment of the present invention in conjunction with drawings.

[0035] As shown in FIGS. 1 to 11, this embodiment provides an intelligent developmental toy based on machine addressing, including: an identification module set 1, a silk screen layer 2 and a toy module set 3. The silk screen layer 2 is mounted on the identification module set 1. The identification module set 1 includes a main control module 101, a multi-way switch module 102, a power management module 103, a signal amplification module 104 and a resonance identification module 105. The power management module 103 is connected with the main control module 101. The resonance identification module 105 is connected to the main control module 101 through the multi-way switch module 102. The signal amplification module 104 is connected to the main control module 101 and the multi-way switch module 102 respectively. The toy module set 3 includes a plurality of toy modules 301. Each toy module 301 is provided with at least one resonance circuit module 302. The resonance circuit module 302 is used for representing the identity of the uniquely corresponding toy module 301, and matching with the resonance identification module 105 of the identification module set 1.

[0036] The identification module set 1 described in this embodiment refers to a working base of the intelligent developmental toy, in which a circuit board is provided for matching and identifying the toy module set 3, realizing machine addressing, that is, realizing automatic identification of the identity and position of the toy module set 3. The silk screen layer 2 refers to a silk screen decorative surface mounted on the identification module set 1 (working base), and the toy module set 3 includes any one kind or multiple kinds of tangram module set, puzzle module set, chess module set, and early educational calculation module set. For example, when the toy module set 3 is a tangram module set, the silk screen layer 2 is an assembly plane of the tangram; when the toy module set 3 is a chess module set, the silk screen layer 2 is the chess grid plane for playing chess.

[0037] The identification module set 1 described in this embodiment further preferably includes an LCD display module 106 and a flash memory module 107. The LCD display module 106 is connected to the main control module 101 and the power management module 103 respectively, and the flash memory module 107 is connected to the main control module 101 and the power management module 103 respectively, so as to be able to well realize the functions of LCD display and data flash memory.

[0038] As shown in FIG. 1, the identification module set 1 of this embodiment includes a main control module 101, a multi-way switch module 102, a power management module 103, a signal amplification module 104, a resonance identification module 105, an LCD display module 106 and a flash memory module 107. In practical applications, the main control module 101, the multi-way switch module 102, the power management module 103, the signal amplification module 104, and the flash memory module 107 are preferably arranged at a bottom of the identification module set 1; other areas of the identification module set 1 are used to arrange the resonance identification module 105, that is, the resonance identification module 105 is a working area of the identification module set 1, and is preferably arranged at a middle part and an upper part of the identification module set 1, so as to provide more game space for the intelligent developmental game; the LCD display module 106 can adopt an external display screen, or other display screens.

[0039] As shown in FIG. 3, the resonance identification module 105 of this embodiment includes a plurality of X-axis circuits 1051 and a plurality of Y-axis circuits 1052, wherein the intersection points of the X-axis circuits 1051 and the Y-axis circuits 1052 are the coordinate points of the resonance identification module 105; the X-axis circuit 1051 refers to a coil arranged horizontally, and the Y-axis circuit 1052 refers to a coil arranged vertically; the plurality of X-axis circuits 1051 and the plurality of Y-axis circuits 1052 are respectively connected to the multi-way switch module 102.

[0040] Although the electromagnetic field is invisible and intangible, when a circuit/coil emits a square wave signal in a certain frequency, an electromagnetic field will be formed and electromagnetic waves will be output; the coil placed directly above it will receive this electromagnetic wave. When the fixed resonance frequency of the coil directly above is same as the frequency below, the amplitude of the coil directly above will increase exponentially, that is, resonance will occur. The coil above will also generate electromagnetic waves. The larger the amplitude, the greater the corresponding induced electromotive force.

[0041] In the vertical and horizontal coordinates of the resonance identification module 105 described in this embodiment, multiple circuits are arranged in the horizontal and vertical directions respectively, each circuit is a corresponding coil, and each coil is independent. For example, the fifth vertical coordinate from left to right sends a square wave signal, that is, the fifth Y-axis circuit 1052 sends a square wave signal. When the resonance circuit module 302 of the toy module 301 above stays here, the fifth Y-axis circuit 1052 will receive the electromotive force generated by the resonance circuit module 302 of the toy module 301 above, so it can be determined that the position of the toy module 301 at this time is located at the fifth vertical coordinate. Similarly, the horizontal coordinate where the toy module 301 is located can be obtained, so that the position of the toy module 301 can be automatically determined, and the machine addressing can be well realized.

[0042] Of course, it is not enough to just realize position identification, because the same toy module 3 may include multiple toy modules 301, such as a tangram includes multiple tangram modules in different shapes and sizes; therefore, each toy module 3 also needs to be identified.

[0043] As shown in FIG. 4, the resonance circuit module 302 of this embodiment includes an inductor and a capacitor connected in series, the inductors of different toy modules 301 are the same, and the capacitors of different toy modules 301 are different, and each toy module 301 includes a corresponding fixed resonance frequency, and this is used as the identity of the toy module 301. It is worth noting that in this embodiment, the inductors of the resonant circuit module 302 of each toy module 301 are the same, and the capacitors are different, so that different fixed resonance frequencies will be generated, and the fixed resonance frequency is the identity of the toy module 301. For different toy modules 301, it is only necessary to replace capacitors in different capacitance values to give them new identities. In practical applications, changing the inductor can also change the fixed resonance frequency, but since changing the inductor is not convenient in the production and processing process, and the cost is high, so this embodiment preferably realizes the identity assignment between different toy modules 301 by changing the capacitor.

[0044] When the toy module 301 is placed on the resonance identification module 105, the main control module 101 sends a square wave of a preset frequency range to the X-axis circuits 1051 and the Y-axis circuits 1052 of the resonance identification module 105 through the multi-way switch module 102. The square wave of the preset frequency range preferably adopts a square wave of 120 KHz1000 kHz frequency. In practical applications, it can also be set and adjusted according to actual needs; until the sent frequency is the same as the fixed resonance frequency of the current toy module 301, resonance is generated to charge the capacitor in the resonance circuit module 302, so as to identify the identity and coordinate point of the current toy module 301. Among them, the identification process of the coordinate point has been described above, that is, machine addressing is realized; and for the identification of the identity, an identity identification table can be preset, and the identity identification table is used for storing the identity of the toy module 301 and its unique corresponding fixed resonance frequency. After obtaining the fixed resonance frequency of the current toy module 301, the identity of the toy module 301 can be quickly obtained by querying the identity identification table. The advantage of such a design of this embodiment is that the toy module 301 does not need to be equipped with a power supply, and a wireless induction method is adopted between the toy module 301 and the resonance identification module 105, which is similar to wireless induction charging. The principle is simple to implement and the game process is less limited.

[0045] As shown in FIGS. 5 and 6, the main control module 101 of this embodiment preferably uses a CPU to implement its main control circuit. When the CPU drives the circuit board to oscillate at a certain frequency, each frequency corresponds to a toy module 301. The fixed resonance frequency of each toy module 301 is recorded in advance through the identity identification table. If there are forty toy modules 301, there are forty corresponding fixed resonance frequencies. Then the forty fixed resonance frequencies are output in sequence through the main control module and scanned. The PWM time parameter of the CPU is set by default as: PWM time parameter=CPU operating frequency/fixed resonance frequency1. The toy modules 301 with the same fixed resonance frequency generate resonance to charge its capacitor. Since the remaining modules are not resonant and have no amplitude, they cannot be charged, and cannot be discharged.

[0046] When the resonance identification module 105 fills the capacitor of the resonance circuit module 302, it stops and the resonance identification module 105 becomes a receiving board, because the corresponding capacitor is already fully charged. Therefore, the capacitor is discharged, and the LC oscillation circuit of the resonance circuit module 302 continues to oscillate at a fixed frequency. At this time, the X-axis circuit 1051 and the Y-axis circuit 1052 at the location of the corresponding toy module 301 can sense a certain electromotive force. This electromotive force is very weak, so it is necessary to form a voltage of 1 v3.2 v after four-stage amplification in the subsequent signal amplification module 104; the ordinate and abscissa corresponding to the X-axis circuit 1051 and the Y-axis circuit 1052 have been connected to the AD conversion pin of the CPU through the PCB board in the prefabricated circuit, and the x-axis and y-axis with the highest modulus value obtained after AD conversion (i.e. analog-to-digital conversion) can be determined as the position of the corresponding toy module 301.

[0047] In practical applications, when the main control module 101 of this embodiment sends a square wave signal at a certain frequency, an array can be set first, and various frequencies can be put into the array. According to the size, the square wave signal with the smallest frequency is first transmitted. If the corresponding chess piece or other toy module 301 that can generate resonance is on the resonance identification module 105 (working base), discharge will be generated, and the maximum AD conversion value of the x-axis and y-axis will be found out through checking CPU or single-chip microcomputer, and then the row number and column number are recorded. This is the position of the toy module 301. If there is no working toy module 301, it means that the corresponding toy module 301 is not on the resonance identification module 105. Then change to the next frequency, and continue to find whether there is a corresponding toy module 301, and so on until the scanning is completed or the corresponding toy module 301 is found out.

[0048] After the identity and position of the toy module 301 are determined, it means that the toy module 301 is determined, and the remaining thing is to arrange it. In this embodiment, the arrangement of various toy modules 301 can be pre-stored in the flash memory module 107 (FLASH), and then by comparing with the database of the flash memory module 107, it is quickly determined whether the arrangement order of the toy modules 301 is correct. Regarding this point, since the existing method can be used, it will not be described in detail.

[0049] As shown in FIG. 7, the signal amplification module 104 described in this embodiment includes a transmitting and receiving conversion circuit 1041, a first amplification circuit 1042, a second amplification circuit 1043 and an integral circuit 1044. The transmitting and receiving conversion circuit 1041 is connected to the second amplification circuit 1043 through the first amplification circuit 1042; the second amplification circuit is connected to the integral circuit 1044 and connected to the main control module 101; it is worth noting that the first amplification circuit 1042 and the second amplification circuit 1043 are both two-stage amplification circuits. Therefore, the signal amplification module 104 described in this embodiment implements four-stage amplification so that the induced weak electromotive force can be amplified and integrated to facilitate subsequent signal detection and analog-to-digital conversion, that is, each chip completes two-stage amplification, and a voltage of 1-3V is formed after four-stage amplification, and the AD conversion pin of the CPU is converted into a 12-bit value.

[0050] As shown in FIG. 8, the multi-way switch module 102 of this embodiment includes a plurality of switch control chips 1021, and the chip select pins of the plurality of switch control chips 1021 are connected in parallel to the main control module 101. In this embodiment, the preferred used number of X-axis circuits 1051 and Y-axis circuits 1052 are 24 and 40 respectively, which is a total of 64 circuits, and realizes 64 coils. Each switch control chip 1021 has 7 switch control chips 1021, the upper 5 switch control chips 1021 are used to realize X-axis switch control, and the lower 2 switch control chips 1021 are used to realize Y-axis switch control; the chip is controlled by its chip select pin, that is, the chip select pins of the plurality of switch control chips 1021 are connected in parallel to the main control module 101. The advantage of such a design is that it can effectively reduce the CPU pins occupied, which is conducive to the miniaturization design of the circuit module.

[0051] As shown in FIG. 9, the power management module 103 in this embodiment includes a lithium battery management circuit 1031 and a battery switch control circuit 1032. The lithium battery management circuit 1031 and the battery switch control circuit 1032 are respectively connected to the main control module 101 to achieve switch protection and control and ensure the stability and reliability of the product.

[0052] Next, this embodiment will introduce and illustrate different types of toy modules 3.

[0053] Regarding letters, numbers and chess pieces, generally in the game, these products only need to detect their identity and position, and the angle is not considered. Therefore, each letter, number and chess piece only corresponds to one toy module 301. Take numbers as an example: when the display screen shows 2+3=? on the working base of the resonance identification module 105, if the number 5 is placed, because the toy module 301 of the number 5 is provided with a resonance circuit module 302, the resonance identification module 105 will determine whether the identity of the current toy module 301 corresponds to 5. If so, it is judged to be correct and the next one will be carried out; if not, a prompt will be issued until the correct toy module 301 of the number 5 is placed. Take letters as an example: if the display screen shows the Chinese word for apple, and requires the corresponding word to be spelled out; then, it will automatically identify that they are all 5 toy modules 301 corresponding to apples placed in order.

[0054] It is worth noting that the above examples do not consider the direction. However, in actual intelligent developmental toys, some need to consider the directionality of placement, such as tangrams, which not only need to identify identity and position, but also need to identify angles. Therefore, this embodiment takes the triangle block as an example. As shown in FIG. 10, a same toy module 301 of this embodiment includes two independently arranged resonance circuit modules 302 with the same fixed resonance frequency, so as to identify the coordinate points and placement direction of the toy module 301. When the same toy module 301 includes two independently arranged resonance circuit modules 302 with the same fixed resonant frequency, one of the resonance circuit modules 302 is the main module, which is also called as the position module and is used for identifying the position; the other resonance circuit module 302 is an angle module, which is used to determine the angle information. By comparing the values of x-axis and y-axis between the angle module and the main module, the angle can be well obtained. The angle can also be confirmed by tan , and the formula is tan =y/x, where x is the x-axis difference value between the main module and the angle module, and y is the y-axis difference value between the main module and the angle module.

[0055] As shown in FIG. 11, in an intelligent developmental toy for training concentration and memory, there are preferably 16 grids on the display screen, and the numbers 1, 2, 3, 4, and 5 are displayed in the grids. At this time, the numbers are displayed within a preset time, and the preset time is adjustable. Then the numbers are turned off and the display screen is blank. At this time, the user need to click the grids in the corresponding area in order from 1 to 5. Only when the user click correctly can it be judged as successful. Therefore, the user must remember not only the position, but also the order, which facilitates to achieve the training of concentration and memory.

[0056] As shown in FIG. 12, taking playing military chess as an example, in the process of placing the dark chess: 1. The position of the chess piece can be determined through wireless electromagnetic addressing; 2. The identity and position of the chess piece can be determined by the above mentioned resonance frequency; 3. When the two sides fight, the chess pieces of both sides touch each other, so when it is necessary to distinguish the grade, it can be determined by identity. 4. When the bomb is placed in the first row and the mine is not placed in the last two rows, an alarm is issued. 5. When the military flag is not placed in the base camp, an alarm is issued. 6. Except for the engineer, the other chess pieces cannot turn when moving, otherwise an alarm is issued. It can well meet the actual application needs without the need for a third party to make a judgment.

[0057] In summary, in the identification module set 1 of this embodiment, the resonance identification module 105 is connected to the main control module 101 through the multi-way switch module 102, so as to receive square wave signals in different frequencies. When the frequency of the square wave signal received by the resonance identification module 105 is the same as the fixed resonance frequency of the current toy module 301, resonance is generated to charge the capacitor of the resonance circuit module 302, so as to identify the coordinate point of the current toy module 301; on this basis, the signal amplification module 104 is respectively connected to the main control module 101 and the multi-way switch module 102, so as to amplify the small signal through multi-stage amplification to form a voltage of 1-3V and send it to the main control module 101; in addition, the toy module set 3 includes a plurality of toy modules 301, and each toy module 301 is provided with at least one resonance circuit module 302; the resonance circuit module 302 is used for representing the identity of the unique corresponding toy module 301, and matching with the resonance identification module 105 of the identification module 1.

[0058] Therefore, this embodiment can not only quickly identify the identity of the current toy module 301 through the identification module 1, and accurately determine the coordinate point/position of the toy module 301 to realize the automatic machine addressing function, but also can be compatible with various developmental toy products such as tangram module set, puzzle module set, chess module set, letter module set, and early educational calculation module set, and can further realize their direction recognition. This embodiment can effectively reduce the use limitations of the product, improve the intelligent level of the product, and facilitate the promotion and application of the product.

[0059] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
