DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] As shown in FIG. 1, a brake fluid detection system according to the present invention includes a first device 1, a second device 2 and a third device 3. The first device 1 consists of a detection unit 11 and a data transmission unit connected to each other. The data transmission unit is provided with a wireless communication module 12 which is used to provide a wireless connection for sending and receiving data. The detection unit 11 is a probe arranged with a sensing circuit and in direct contact with a brake fluid to be detected for sensing changes in water content or temperature of the brake fluid.

[0019] The second device 2 is a cloud database composed of a data storage unit 21, a data analysis unit 22, and a data processing unit 23.

[0020] The third device 3 is a portable internet device (such as a cell phone or a tablet) provided with an application software which is used for receiving and displaying data of the brake fluid after detection and having an operation interface 31. The wireless communication module 12 receives detected data obtained through the detection in the fluid tank by the detection unit 11 and sends the detected data to the third device 3 through the wireless connection. Then the detection data is further transmitted to the second device 2 through the third device 3 for data extraction and processing. By operating the operation interface 31, the third device 3 is connected to the first device 1 and the second device 2 correspondingly via the wireless network. The third device 3 is defined to be used as the device for data transmission and operation between the first device 1 and the second device 2 as well as data display. The operation interface 31 of the third device 3 is interactively connected to the detection unit 11 of the first device 1 for getting the detected data and is operated for sending the detected data to the second device 2. Brake fluid related data has been set and stored in the data storage unit 21 of the second device 2 in advance. The brake fluid related data includes types of the brake fluid, oil companies/brands, experimental data for the respective brake fluids, water content, etc. The data analysis unit 22 retrieves the brake fluid related data in the data storage unit 21 together with data set by users received and performs analysis. Then the data processing unit 23 generates the detection data. Next the detection data is obtained by and displayed on the third device 3 so that users can check the detection data in a real-time manner.

[0021] More specifically, the third device 3 is connected to the first device 1 through the wireless connection for getting the detected data and sending the detected data to the second device 2 over the wireless network. The application software of the third device 3 is provided with an operation interface 31 which has a display screen. To put it another way, when the application software is launched, users can perform the operations on the operation interface 31 of the third device 3 which is connected to the first device 1 and the second device 2 for interactively receiving and sending data at the same time.

[0022] The application software is preset in the third device 3 which is a portable internet device (such as a mobile phone or a tablet). The application software is connected to the detection unit 11 of the first device 1 correspondingly through the wireless connection and is also connected to the second device 2 via the wireless network for processing and analyzing the detected data from the detection unit 11. The data analysis unit 22 and the data processing unit 23 are used for data comparison and processing of the detected data received from the first device 1 to generate detection data of the brake fluid. Then the detection data of the brake fluid is retrieved from the second device 2 by the third device 3 through the wireless network and displayed on the third device 3 for users to view.

[0023] The wireless connection mentioned above can be one of the following ways: Bluetooth, Wi-Fi, etc. The wireless connection is defined as connection conducted by wireless modules. The connection is allowed, not necessarily through the internet. For example, the common wireless technologies include Bluetooth (BLE), Wi-Fi, and ZigBee, having short operating range from a few meters to a few hundred meters while LoRa is able to reach coverage ranges up to a few kilometers.

[0024] The wireless network mentioned above is a network in which a device and a carrier network/or internet are connected in a wireless way.

[0025] The data set by users is defined as the data being set by users who perform the operations on the operation interface 31 of the third device 3. For example, the data can be the type of the brake fluid, the brand of the brake fluid or others related to the brake fluid.

[0026] The brake fluid related data is defined as data collected through experiments by brake fluid manufacturers. The brake fluid brake fluid related data is stored in the data storage unit 21 of the second device 2 and retrieved by the data analysis unit 22 and the data processing unit 23 for data comparison and processing. Users are unable to access the brake fluid related data. The experiments are conducted by the manufacturers and the experimental data are saved in the data storage unit 21. The brake fluid related data remains unchanged unless an update is performed.

[0027] The detection data is defined as the detection results obtained after the data detected being processed by the second device 2.

[0028] As shown in FIG. 2, the operation interface 31 of the third device 3 is revealed. A brake-fluid type selection button 311, a brake-fluid brand selection button 312, a test button 313, a print button 314 and a result display button 315 are disposed on the operation interface 31. The operation interface 31 of the applications software is corresponding and connected to the first device 1. When a detection of the brake fluid is carried out at the user end, a wireless connection is established between the operation interface 31 and the first device 1. Then the detection procedure is performed and the detection results are displayed through the operation interface 31. Thereby users can perform the operation quickly and get the detailed detection data of the brake fluid.

[0029] While in use, users press the brake-fluid type selection button 311 and the brake-fluid brand selection button 312 on the operation interface 31 for selecting the type and the brand of the brake fluid to be detected. This is the data set by users. Then insert the detection unit 11 of the first device 1 into the fluid tank and press the test bottom 313 on the operation interface 31 of the third device 3 to command the circuit of the detection unit 11 of the first device 1 to obtain the detected data of the oil product. Next the detection unit 11 sends the detected data of the brake fluid to the wireless communication module 12 of the data transmission unit and then the wireless communication module 12 transmits the detected data to the third device 3 through the wireless connection. The third device 3 is connected to the second device 2 via the wireless network so that the detected data and the data set by users are sent to the second device 2 for data processing. Then the result display button 315 is pressed to send commands to the second device 2 to get the detection data after processing. Lastly the third device 3 displays the detection data. The user presses the print button 314 to output the detection data by printing if he/she wants to print the data.

[0030] The brake fluid related data in the second device 2 includes a comparison database in which data are collected and generated by the experiments or data for comparison which has been established according to international standards. The comparison database is maintained and updated by the brake fluid manufacturers or their dealers. After receiving the detected data and the data set by users from the third device, the cloud database performs data comparison and processing of the detected data according to the data set by users. The data comparison process includes some operations such as conversion of the data or the units, comparison of the value and determination of the results. Once the results come out, the cloud database sends the results back to the third device 3 and the results are the detection data through the network.

[0031] The conventional detection system has the shortcomings such as poor portability and limited storage capacity of the brake fluid related data. The present system solves these problems by the cloud database for analyzing the brake fluid related data, the wireless network through which the third device 3 retrieves the detection data obtained after analysis, and the third device 3 on which the operations are performed and the detection data is displayed. Without any data update process, clients can get access to the most up-to-date data at all times. The volume of the detection end can also be decreased so that not only the cost is reduced, the clients can also move the detection end of the system for detecting the brake fluid freely.

[0032] Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalent.
