DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present invention discloses a computer-aided tester for checking a continuity of a circuit. Taking one of a variety of embodiments as an example, the technology disclosed by the present invention is described in detail below:

[0015] FIG. 1 is a schematic diagram of the structure of the computer-aided tester for checking the continuity of the circuit disclosed by the present invention. The computer-aided tester includes one computer 1 and two handheld inspection parts 3. Each of the two handheld inspection parts 3 is provided with one probe 4 and one illuminating lamp 2, and each of the probe 4 and the illuminating lamp 2 is connected to the computer 1 through a circuit (the circuit connection may be: USB connection or cable connection or WIFI connection). The computer 1 is configured to check the continuity of inspected to-be-checked circuit between the two probes 4 and control the illuminating lamp 2. to be turned on and turned off.

[0016] In practical work, it is often necessary to connect a plurality of handheld inspection parts 3 based on the actual situation of the to-be-checked circuit, so that the continuity of the to-be-checked circuits between a plurality of probes 4 can be checked simultaneously.

[0017] FIG. 2 shows a work flow of the computer-aided tester for checking the continuity of the circuit disclosed by the present invention. According to an inspection solution, the computer 1 issues an inspection instruction and turns on the illuminating lamp 2. With the assist of the illuminating lamp 2, a quality inspector presses the probes 4 on two terminals of the to-be-checked circuit according to the inspection instruction. If the to-be-checked circuit is on, the computer 1 records that the inspection result of the to-be-checked circuit is on and turns off the illuminating lamp 2. If the to-be-checked circuit is off, the quality inspector operates the computer to skip the current inspection instruction, and the computer 1 records that the inspection result of the to-be-checked circuit is off and turns off the illuminating lamp 2. According to the inspection solution, the computer 1 circularly checks the continuity of all circuits until completion, and finally generates an inspection report.

[0018] Specifically, according to a design scheme, the circuit connection diagram or table is first entered into the computer 1. At the beginning of the inspection, according to the entered circuit connection diagram or table, the computer 1 sends out the inspection instructions containing information of the two terminals and wire number of a to-be-checked circuit one by one in a multimedia manner and turns on the illuminating lamp 2 on each of the handheld inspection parts 3. According to the inspection instruction, the quality inspector contacts the probes 4 on the handheld inspection parts 3 with the two terminals of the to-be-checked circuit. If the to-be-checked circuit is determined to be on, the computer 1 turns off the illuminating lamp 2 and records the inspection result. If the to-be-checked circuit is determined to be off, the quality inspector gives a skip instruction to the computer 1, and then the computer 1 turns off the illuminating lamp 2 and records the inspection result. The operations are circularly performed until all the circuits are checked, and the computer 1 generates the final inspection report.
