Problems solved by technology

[0002] At present, the production test of our comprehensive protection device adopts a purely manual method. The operator manually positions the device behind the test tooling, and manually completes the external input test such as analog quantity acquisition, input quantity, etc., as well as channel zero point calibration and channel coefficient. Calibration and other factory settings. After completing the relevant operations, manually fill in the test record data in the pre-printed test report. All links are completed by the operator. There are many unreliable factors, high risks, and low efficiency. With the company's Development, increase in shipments, manual production test mode will become a bottleneck restricting development

Embodiment Construction

[0090] 1.1 Functional requirements of the present invention:

[0091] Communication function detection: The PC sends a communication command to check whether the device under test responds correctly. If there is no reply or a wrong reply then there is a problem with the communication channel.

[0092] Single-chip ROM self-test: Check whether there is a bad bank in the ROM of the single-chip microcomputer. Use the sampling address read and write detection scheme. After the device receives the ROM self-test command issued by the PC, the device selects fixed addresses in several fixed areas to perform read and write operations. If there is an inconsistency between the written and read data. It means that there is a bad bank in the ROM area. Then it is determined that there is a problem with the ROM of the single-chip microcomputer.

[0093] Single-chip RAM self-test: Check whether the single-chip RAM has a bad bank. Use the sampling address read and write detection scheme. ...

Abstract

The invention relates to an automatic testing system of a comprehensive protection device. A pure manual mode is adopted in the conventional production testing; after a device is manually positioned on a testing tool by an operator, analog acquisition, testing of external input such as input and factory setting such as channel zero calibration and calibration of a channel coefficient are manually finished; and after relative operation is finished, test record data is filled manually in a preprinted test report, and all steps are finished by the operator, so that more unreliability factors, high risk and low efficiency are caused. According to the automatic testing system, whether hardware of the YZ series comprehensive protection devices work normally can be quickly detected in an automatic mode, and a clear problem existing in the hardware is positioned through detection. According to the system, the conventional manual testing process can be substituted, the operation is easy, the use is convenient, the testing of the comprehensive protection device can be finished by only operating a PC (Personal Computer) by the operator, the production test efficiency can be greatly increased, and the production test cost is reduced.
