[0001] The present invention relates to the technical field of computer detection, and in particular to an intelligent detection system and method for an electronic detonator control module. Background Art
[0002] The existing laboratory testing of electronic detonator control modules uses a manual method to build the test environment. First, a foot wire of a specific length is welded to each electronic detonator control module; then, an electrical connection is formed with the busbar through the foot wire clamp, and one end of the busbar is connected to the detonator handheld device; then, the electronic detonator control module is entered, networked, charged, and detonated on the detonator handheld device; finally, after several detonation processes, the laboratory testing of the electronic detonator control module is completed.
[0003] Although the screening of abnormal modules and the testing of the entire detonation system hardware and firmware can be completed by manually building a test environment, there are many defects in the manual construction of the test environment: on the one hand, each time the experimental conditions are changed, the test environment needs to be rebuilt, especially the connection of the foot wire / busbar, which leads to huge consumption of manpower and material resources; on the other hand, the manually built test environment lacks intelligent detection means, especially for the measurement of delay accuracy. There is a lack of methods or large errors, and it is impossible to judge whether the circuit design is reasonable, resulting in discrepancies in the detonation time of the electronic detonator in actual use, which is prone to safety problems.

[0055] The bus control layer 5 includes a bus switch board 51, a bus 52 and a test rack power supply 53;
[0056] The system controls the handheld device 1 to make the host computer 2 execute the following operations on the intelligent test stand 3:
[0057] The bus switching control module sends out a command to configure the bus length through the host computer 2, which is transmitted from the Android mainboard 22 to the detonation detection board 24 through the 232 serial port, and then transmitted from the detonation detection board 24 to the bus switching board 51 through the 485 serial port.

The module switching board 41 executes the instructions to control the foot line switching board 43 to automatically complete the configuration. If the foot line of the corresponding length cannot be configured, an error message is prompted.
[0059] By applying the electronic detonator control module intelligent detection system and method to laboratory tests that require frequent changes in experimental conditions, welding is no longer required and automatic switching of leg wire / bus bar lengths is achieved, thereby avoiding a large amount of manpower and material resources consumption during electronic detonator control module testing.
[0060] Furthermore, the above implementation also includes a detonation delay detection module, which sets the delay time of the busbar switching control module and the foot line switching control module in the detonation handheld device 1, and completes the input, monitoring and charging in sequence, and then the module control board 41 monitors the detonation instruction sending time t1 and the bridge wire end discharge time t2, and transmits the data back to the host computer 2 for calculation and storage. Then the stored historical data is checked through the screen 21.
[0061] In the above technology, through the detonation monitoring circuit, the delay accuracy test of thousands of batch electronic control modules is realized, which can screen out modules with unqualified delay accuracy and avoid casualties caused by large delay errors of electronic detonators.

[0068] If the configuration fails, no command is sent back, and the host computer 2 displays that the corresponding busbar length / leg length cannot be configured.
[0069] Furthermore, in the execution of bus length configuration in step S03 , the bus switching board 51 executes instructions to control the switch of the corresponding relay, thereby configuring the bus 52 of corresponding length.
[0070] Secondly, in step S03, the bus length configuration is to configure the corresponding length bus 52 by executing the instruction to control the switch of the corresponding relay through the bus switch board 51.
[0071] Furthermore, in step S03 , the leg length is configured by the module switch board 41 executing instructions to control the switch of the corresponding relay on the leg switch board 43 , thereby configuring the leg 44 of the corresponding length.
[0072] Furthermore, the method further includes monitoring the detonation, the steps of which include:
[0073] S05. Set the delay of the busbar switching control module and the foot line in the detonation handheld device 1, and complete the input, monitoring and charging;
[0074] S06, when the module control board 41 detects the detonation instruction sent by the detonation handheld device 1, the current time t1 is recorded;
[0075] S07, when the monitoring detonation circuit of the module control board 41 outputs a low level "0", it means that the module bridge wire end passes through a high voltage, the detonation is completed, and the current time t2 is recorded;
[0076] S08, the module control board 41 transmits the data back to the Android main board 22 via the detonation detection board 24 for storage.
[0077] In the above technology, the delay accuracy of the electronic detonator control module can be accurately and batch-measured through the detonation monitoring method, avoiding casualties caused by large delay errors during on-site use. Through the intelligent switching control of the host computer, batch replacement of module pins / busbars is achieved, and the test experimental conditions can be quickly changed, avoiding the waste of manpower and material resources caused by mechanical operations. Secondly, through the recording of abnormal data of the host computer, the traceability of the electronic control module test is achieved, and the test time, test personnel, abnormal conditions and other information can be accurately traced, avoiding the problem of difficulty in tracing reference test data when the electronic control module is used abnormally on-site.
