Description

Technical Field

[0001] The utility model relates to the field of electronic detonator production, in particular to a second difference test device for electronic detonators and a charge ignition test device. Background Art

[0002] Electronic detonators, also known as digital electronic detonators, utilize an electronic control module to control the detonation process. Before use, electronic detonators require various performance tests, with the second delay test and the charge ignition test being key and important.

[0003] The structure of electronic detonator is as follows Figure 1 As shown, the detonation of the electronic detonator first requires the ignition of the charge head (ignition powder), and the charge head ignition is achieved by energizing the bridge wire inside the charge head, and the electronic control module controls the charging and discharging of the charging capacitors at both ends of the bridge wire to ignite the bridge wire.

[0004] In field applications, the detonation delay can be set for the electronic detonator to achieve delayed detonation. Since the detonation delay accuracy is high, reaching the us level, it is necessary to ensure that the module detonation delay accuracy meets a certain standard. The second detection equipment is used to test the detonation delay accuracy of the electronic detonator.

[0005] The cartridge ignition test is to detect the charging and discharging characteristics of different types of charging capacitors and the resistance of the bridge wire. The ignition voltage is adjusted by the raising and lowering method, and the minimum ignition voltage and the maximum non-ignition voltage are recorded. Multiple tests are performed according to this step. Finally, all recorded data are substituted into a specific formula to confirm the ignition status of the cartridge.

[0006] Currently, electronic detonator second-error testing and charge ignition testing are performed using separate equipment. This requires connecting the electronic detonator to the second-error testing equipment and the charge ignition testing equipment separately, resulting in a high workload and low test efficiency. Furthermore, both the second-error testing equipment and the charge ignition testing equipment currently use independent external power supplies, making them bulky and difficult to move and use at the installation site (blasting site).

[0147] S7, real-time monitoring to see whether the electronic detonator explosion signal is received. If so, proceed to step S8; if not, proceed to step S9. The electronic detonator explosion signal can be obtained by using a piezoelectric sensor to obtain a voltage signal, or it can be a voltage signal received by a photoelectric sensor, as long as it is an electronic signal that can reflect the explosion of the charge head;

[0158] SF7. A new test ignition voltage is obtained according to the voltage step value adjustment, and then steps S2-S6 are performed until the minimum ignition voltage for the cartridge ignition and the maximum ignition voltage for the cartridge not to ignite are obtained.

[0159] In this embodiment, the PID dynamic adjustment in step SF4 includes the following steps:

[0160] SH1. Get the current voltage value;

[0161] SH2. Determine whether the current voltage is the test ignition voltage. If so, proceed to step SH3. If not, proceed to step SH4.

[0162] SH3, obtain ignition voltage;

[0163] SH4, if not, perform incremental PID calculation of voltage output, and then output the theoretical DAC value;

[0164] SH5. Compare the difference between the output theoretical DAC value and the set voltage, adjust the incremental PID calculated voltage output, and wait for the execution cycle time to arrive before entering SH1.
