Description

Technical Field

[0001] The present invention relates to the technical field of initiator detection, and particularly to an intelligent and safe initiator detection device. Background Art

[0002] Initiators have high reliability requirements, and their detection work is somewhat dangerous. In order to ensure the high efficiency of the detection work and the safety of the detection personnel, special intelligent and safe detection instruments are required to accurately detect the initiators while having high intelligent safety.

[0003] In the initiator detection project, it is necessary to detect the resistance value of the bridge resistance of the initiator and randomly select some products for actual firing tests to ensure that the initiator can meet the firing requirements. At the same time, the non-firing situation under the safe current condition of the initiator will also be tested to ensure that the initiator cannot fire within a certain current and fixed time period. Currently, the existing initiator detection equipment usually has the following problems: (1) Simple functions, that is, the existing initiator detection equipment is for single-type initiator detection, and there is no general-purpose detection equipment. Therefore, during the batch detection of initiators, manual detection of initiators is still relied on to a large extent, which reduces the efficiency of the detection work and increases the use risk of initiators; (2) Poor intelligence, that is, the detection of the bridge resistance of the initiator and the firing test usually use independent and special detection instruments respectively, which cannot be quickly carried out during the random inspection of batch initiators, reducing the efficiency of the detection work; (3) Insufficient relevant safety measures, increasing the use risk of initiators during the batch detection of initiators.

[0024] Hereinafter, with reference to the attached Figure 2-4 to describe the intelligent safety type initiating explosive device detection device of the embodiments of the present application.

[0025] Figure 1 The connection relationship diagram of the intelligent safety type initiating explosive device detection device of the present invention with an external power supply and an initiating explosive device to be detected is shown, Figure 2The structural schematic diagram of the intelligent and safe initiator detection device of the present invention is shown.

[0026] Referring Figure 1 and Figure 2 For the intelligent and safe initiator detection device 100 according to the embodiments of the present application, it includes a first power conversion module 10, a second power conversion module 20, a resistance measurement module 30, a timing inspection module 40, and a control module 50.

[0027] The first power conversion module 10 is used to connect to an external power supply 200, and the first power conversion module 10 is connected to the resistance measurement module 30, the timing inspection module 40, and the control module 50. The first power conversion module 10 is used to convert the alternating current of the external power supply 200 into direct current to supply power to the resistance measurement module 30, the timing inspection module 40, and the control module 50. Specifically, the external power supply 200 can be 220V alternating current, and the first power conversion module 10 can convert 220V alternating current into 24V direct current.

[0028] The second power conversion module 20 is used to connect to the external power supply 200, and the second power conversion module 20 is connected to the timing inspection module 40. The second power conversion module 20 is used to convert the alternating current of the external power supply 200 into direct current and load a timing signal (i.e., a voltage signal) to the initiator 300 to be detected through the timing inspection module 40. Specifically, the external power supply 200 can be 220V alternating current, and the second power conversion module 20 is a voltage adjustable power module, that is, the second power conversion module 20 can convert 220V alternating current into direct current within the range of 0 - 50V under the action of the timing inspection module 40; further, the second power conversion module 20 can convert 220V alternating current into direct current within the range of 0 - 36V.

[0029] The resistance measurement module 30 is connected to the first power conversion module 10 and the control module 50 and is used to connect to at least one initiator 300 to be detected to realize the internal resistance detection of each initiator 300 to be detected.

[0030] It can be understood that the resistance measurement module 30 is powered by the first power conversion module 10, and the resistance measurement module 30 can be connected to one initiator 300 to be detected, or can be connected to multiple initiators 300 to be detected (the types of multiple initiators 300 to be detected can be the same or different) to simultaneously realize the internal resistance detection of multiple or multiple types of initiators 300 to be detected. Moreover, the resistance measurement module 30 realizes the internal resistance detection of each initiator 300 to be detected by loading a corresponding current to each initiator 300 to be detected.

[0031] In addition, it should be noted that due to the redundancy design requirements of initiators, generally, the bridge circuits (with bridge resistors) of initiators appear in pairs or multiple pairs simultaneously. Therefore, in order to detect the resistance values of each bridge resistor of the initiator 300 to be detected, the resistance measurement module 30 can be connected to the multiple bridge circuits of each initiator 300 to be detected.

[0032] The timing inspection module 40 is connected to the first power conversion module 10 and the second power conversion module 20 and is used to be connected to at least one initiator 300 to be detected for performing ignition inspection on the initiator 300 to be detected.

[0033] It can be understood that the timing inspection module 40 is also powered by the first power conversion module 10, and the timing inspection module 40 can be connected to one initiator 300 to be detected or can be connected to multiple initiators 300 to be detected (the types of multiple initiators 300 to be detected can be the same or different) to simultaneously perform ignition inspection on multiple or multiple types of initiators 300 to be detected. Moreover, the timing inspection module 40 adjusts the output voltage of the second power conversion module 20 to load a timing signal (i.e., a voltage signal) to the initiator 300 to be detected.

[0034] The control module 50 is connected to the first power conversion module 10, the resistance measurement module 30, and the timing inspection module 40, and is used to generate measurement and control information for the resistance measurement module 30 and / or the timing inspection module 40 according to the parameter information of the initiator 300 to be detected obtained.

[0035] Specifically, the control module 50 is the control center device of the intelligent safety initiator detection device 100, and special initiator detector software can be pre-installed inside it. Therefore, the control module 50 can realize the entry of the incoming factory information (including parameter information) of the initiator 300 to be detected and the generation of the outgoing factory quality report after detection based on the manual method or the scanning method. That is, when the internal resistance detection of the initiator 300 to be detected is required, the control module 50 can obtain the parameter information of the initiator 300 to be detected and generate the first measurement and control information for controlling the resistance measurement module 30 and receive the internal resistance information of the initiator 300 to be detected detected by the resistance measurement module 30; when the ignition inspection of the initiator 300 to be detected is required, the control module 50 can obtain the parameter information of the initiator 300 to be detected and generate the second measurement and control information for controlling the timing inspection module 40 and receive the timing information (i.e., voltage signal) of the initiator 300 to be detected detected by the timing inspection module 40. In addition, the control module 50 can also realize the display of the load voltage, load current, test time, incoming factory information, outgoing factory quality report, system operation status, etc.

[0036] In the embodiment of the present application, based on the power supply of the first power conversion module 10 to the resistance measurement module 30 and the control module 50, and the cooperation between the resistance measurement module 30 and the control module 50, the internal resistance detection of one or more detonators 300 to be detected can be quickly realized; at the same time, based on the power supply of the first power conversion module 10 to the timing inspection module 40 and the control module 50, and the cooperation between the timing inspection module 40, the second power conversion module 20 and the control module 50, the firing inspection of one or more detonators 300 to be detected can be quickly realized. Therefore, the intelligent safety detonator detection device 100 of the present application has both the internal resistance detection function and the firing inspection function, and can use a set of devices to realize the internal resistance detection and firing inspection of one or more detonators 300 to be detected, greatly improving the detection efficiency; at the same time, based on the cooperation between the control module 50 and the timing inspection module 40 and the timing inspection module 40, the control module 50 can intelligently control the timing inspection module 40 and the timing inspection module 40, thereby reducing the use risk of detonators during the batch detection of detonators.

[0037] Figure 3 The structural schematic diagram of the resistance measurement module of the present invention is shown.

[0038] Refer to Figure 3 , the resistance measurement module 30 includes a first processor 31, a current signal transmission unit 32 and a voltage signal acquisition unit 33.

[0039] The first processor 31 is communicatively connected to the control module 50, and is configured to receive the first measurement and control information sent by the control module 50 and upload the collected data. Specifically, the first processor 31 may be an ARM processor, and the first processor 31 may be communicatively connected to the control module 50 through the UART and RS422 communication protocols.

[0040] The current signal transmission unit 32 is connected to the first processor 31 and is configured to be connected to at least one detonator 300 to be detected, and is configured to transmit a corresponding target current to each detonator 300 to be detected. It can be understood that the first processor 31 can transmit (i.e., load) a corresponding target current to each detonator 300 to be detected by controlling the current signal transmission unit 32 according to the received first measurement and control information. Specifically, the target current transmitted by the current signal transmission unit 32 may be in the range of 0 to 20 mA, and can output the target current to the detonator 300 to be detected in a constant current manner within a certain time period.

[0041] The voltage signal acquisition unit 33 is connected to the first processor 31 and is used to be connected to at least one initiator to be detected 300. The voltage signal acquisition unit 33 is used to collect the voltage across the initiator to be detected 300 in the state where each initiator to be detected 300 is loaded with a corresponding target current and transmit it to the first processor 31. The first processor 31 determines the internal resistance of each initiator to be detected 300 based on the voltage across each initiator to be detected 300 and the corresponding target current, and sends the internal resistance information to the control module 50.

[0042] In this embodiment, through the cooperation among the first processor 31, the current signal transmission unit 32, and the voltage signal acquisition unit 33, the resistance measurement module 30 can load a target current to the initiator to be detected 300 and collect the voltage across the initiator to be detected 300 in the state where the target current is loaded. Thus, the first processor 31 can calculate the internal resistance of the initiator to be detected 300 based on the voltage across the initiator to be detected 300 and the loaded current. At the same time, based on the interaction between the first processor 31 and the control module 50, the informatization level in the initiator detection and management process is increased. Through the control of the first processor 31 by the control module 50, data transmission can be facilitated and a large amount of data can be stored for a long time, thereby avoiding mistakes caused by manual operations.

[0043] Refer to Figure 3 , the current signal transmission unit 32 includes at least one first digital-to-analog conversion chip 321 and at least one constant current source 322.

[0044] The number of the first digital-to-analog conversion chips 321 is one or more. Each first digital-to-analog conversion chip 321 can be connected to the first processor 31 through the SPI communication protocol, and is used to convert the digital signal sent by the first processor 31 into an analog signal and can output at least one path of analog quantity signal. Specifically, each first digital-to-analog conversion chip 321 is a D / A chip, and each first digital-to-analog conversion chip 321 can output 1 path, 2 paths, 3 paths, 4 paths or more than 4 paths of analog quantity signals.

[0045] Each constant current source 322 is connected to a corresponding first digital-to-analog conversion chip 321 and at least one initiator to be detected 300, and is used to transmit the target current corresponding to each path of analog quantity signal to the corresponding initiator to be detected 300 in a constant current manner. It can be understood that the number of the constant current sources 322 is one or more, and can be specifically determined according to the number of the analog quantity signals output by the first digital-to-analog conversion chip 321. For example, the constant current sources 322 can be set in one-to-one correspondence with the first digital-to-analog conversion chips 321, and each constant current source 322 can output multiple paths of current signals.

[0046] In this embodiment, the conversion between digital signals and analog signals is achieved through the first digital-to-analog conversion chip 321, and the constant current output of the target current is achieved through the constant current source 322, so that the first processor 31 can control the target current of multiple paths of 0-20 mA to be output to the explosive train 300 to be detected in a constant current manner through the first digital-to-analog conversion chip 321. Therefore, multi-path internal resistance detection can be realized, and more types of explosive trains can be adapted. Thus, the detection efficiency can be significantly improved during the detection of a large number of explosive trains, and the informatization level in the process of explosive train detection management is increased, thereby reducing human errors.

[0047] In some embodiments, the number of the first digital-to-analog conversion chips 321 is two, and the number of the constant current sources 322 is also two. Each first digital-to-analog conversion chip 321 can output 4 channels of analog signals, and each constant current source 322 is connected to a corresponding first digital-to-analog conversion chip 321 and can output the 4 channels of analog signals to four explosive trains 300 to be detected respectively.

[0048] Refer to Figure 3 , the voltage signal acquisition unit 33 includes a first analog-to-digital conversion chip 331 and at least one signal amplification circuit 332.

[0049] The first analog-to-digital conversion chip 331 can be connected to the first processor 31 through the SPI communication protocol, and is used for converting the analog signals sent by the signal amplification circuit 332 into digital signals. Specifically, each first digital-to-analog conversion chip 321 is an A / D chip, and each first digital-to-analog conversion chip 321 can simultaneously convert 1 channel, 2 channels, 3 channels, 4 channels or more than 4 channels of analog signals into digital signals.

[0050] The number of the signal amplification circuits 332 is one or more. Each signal amplification circuit 332 is connected to the first analog-to-digital conversion chip 331 and a corresponding explosive train 300 to be detected, and is used for amplifying the voltage across the explosive train 300 to be detected and then transmitting it to the first analog-to-digital conversion chip 331, so as to be sent to the first processor 31 through the first analog-to-digital conversion chip 331.

[0051] In this embodiment, the acquisition, amplification and output of the voltage across the explosive train 300 to be detected are achieved through the signal amplification circuit 332, and the conversion between the acquired analog signals and digital signals is achieved through the first analog-to-digital conversion chip 331, so that the first processor 31 can control the signal amplification circuit 332 to acquire the voltage across one or more explosive trains 300 to be detected through the first analog-to-digital conversion chip 331. Therefore, multi-path internal resistance detection can be realized, and more types of explosive trains can be adapted. Thus, the detection efficiency can be significantly improved during the detection of a large number of explosive trains, and the informatization level in the process of explosive train detection management is increased, thereby reducing human errors.

[0052] Reference Figure 2 The intelligent and safe initiator detection device 100 further includes a working indicator light L1 and an alarm indicator light L2, and the resistance measurement module 30 further includes a first digital quantity control unit 34 and a second digital quantity control unit 35.

[0053] The first digital quantity control unit 34 is connected to the first processor 31 and the working indicator light L1, and is used to control the working indicator light L1 to be turned on or off. The second digital quantity control unit 35 is connected to the first processor 31 and the alarm indicator light L2, and is used to control the alarm indicator light L2 to be turned on or off.

[0054] It can be understood that the working indicator light L1 is used for indication during normal operation. When the intelligent and safe initiator detection device 100 is powered on and passes the self-check, the working indicator light L1 flashes. The alarm indicator light L2 is used for indication during a working fault. When the intelligent and safe initiator detection device 100 fails to pass the self-check or operates abnormally after being powered on, the alarm indicator light L2 flashes. Among them, the self-check function can adopt the method of automatically testing the resistance of the internal simulated initiator and calibrating by subtracting the resistance of the cable.

[0055] In this embodiment, the first processor 31 outputs a digital quantity for controlling the working indicator light L1 through the first digital quantity control unit 34 to control the working indicator light L1 to be turned on or off, and outputs a digital quantity for controlling the alarm indicator light L2 through the second digital quantity control unit 35 to control the alarm indicator light L2 to be turned on or off. Thus, the working state monitoring and detection of the intelligent and safe initiator detection device 100 can be realized, thereby increasing the safety during the internal resistance detection process of the initiator 300 to be detected, and thus improving the detection protection of the initiator 300 to be detected and the safety protection of the operator.

[0056] Reference Figure 3 The resistance measurement module 30 further includes a first DC / DC conversion unit 36. The first DC / DC conversion unit 36 is connected to the first power conversion module 10 and is used to supply power to the first processor 31, that is, the first DC / DC conversion unit 36 is used to convert the voltage output by the first power conversion module 10 and then supply it to the first processor 31.

[0057] Figure 4 The structural schematic diagram of the resistance measurement module of the present invention is shown.

[0058] Reference Figure 4 The timing verification module 40 includes a second processor 41, an adjustment unit 42, at least one voltage signal transmission unit 43, and a timing signal acquisition unit 44.

[0059] The second processor 41 is communicatively connected to the control module 50 and is configured to receive the second measurement and control information sent by the control module 50 and upload the collected timing data (such as the voltage data at both ends of the initiator 300 to be detected). Specifically, the second processor 41 can be an FPGA processor, and the second processor 41 can be communicatively connected to the control module 50 through the UART and RS422 communication protocols.

[0060] The adjustment unit 42 is connected to the second processor 41 and the second power conversion module 20 and is configured to adjust the output voltage and output current of the second power conversion module 20. Specifically, the second processor 41 can output an analog quantity to the second power conversion module 20 through the adjustment unit 42 to achieve the adjustment of the output voltage and output current of the second power conversion module 20.

[0061] The voltage signal transmission unit 43 can be one or more. Each voltage signal transmission unit 43 is a transmission channel, which is connected to the second processor 41 and the second power conversion module 20, and each voltage signal transmission unit 43 is configured to be connected to the corresponding initiator 300 to be detected, so as to load the target voltage output by the second power conversion module 20 to the initiator 300 to be detected for firing test of the initiator 300 to be detected.

[0062] The timing signal acquisition unit 44 is connected to the second processor 41 and is configured to be connected to at least one initiator 300 to be detected. The timing signal acquisition unit 44 is configured to acquire the voltage across the initiator 300 to be detected when each initiator 300 to be detected is loaded with the corresponding target voltage, so that the second processor 41 can determine the current of the initiator 300 to be detected according to the voltage across the initiator 300 to be detected.

[0063] In this embodiment, the second processor 41 adjusts the output voltage and output current of the second power conversion module 20 through the adjustment unit 42, so that the target voltage can be loaded to each initiator 300 to be detected through the voltage signal transmission unit 43 for firing test and opening of safety mechanisms, fuses, and electromagnetic pins, etc. Therefore, based on the cooperation of the second processor 41, the adjustment unit 42, the voltage signal transmission unit 43, and the timing signal acquisition unit 44, and by limiting the output current of the initiator 300 to be detected and the duration of the transmission voltage of the voltage signal transmission unit 43, the non-firing condition of the initiator 300 to be detected under the safe current condition can be tested to ensure that the initiator 300 to be detected cannot fire within a certain safe current and a fixed time period.

[0064] In addition, it should be noted that for products such as safety mechanisms, insurance devices, and electromagnetic pins, when the actuator is required to cooperate for inspection, the device has a multi-channel time-sequence configurable output function. It can output multi-channel high-precision time-sequence voltage and current signals according to the set process and time, respectively control the safety mechanism, insurance device, and electromagnetic pins to work according to the set process, and then issue the ignition time-sequence, so as to complete the firing test of the initiator.

[0065] Referring to Figure 4 , the adjustment unit 42 includes a first opto-isolation device 421, a second digital-to-analog conversion chip 422, and a third digital-to-analog conversion chip 423.

[0066] The first opto-isolation device 421 is connected to the second processor 41 through the SPI communication protocol. The second digital-to-analog conversion chip 422 is connected to the first opto-isolation device 421 and the second power conversion module 20. The third digital-to-analog conversion chip 423 is connected to the first opto-isolation device 421 and the second power conversion module 20. Among them, the second digital-to-analog conversion chip 422 is a D / A chip for converting digital signals into analog signals, so as to adjust the output voltage of the second power conversion module 20. The third digital-to-analog conversion chip 423 is also a D / A chip for converting digital signals into analog signals, so as to adjust the output current of the second power conversion module 20.

[0067] It can be understood that the second processor 41 controls the second digital-to-analog conversion chip 422 and the third digital-to-analog conversion chip 423 to output analog signals to the voltage adjustment and current adjustment terminals of the second power conversion module 20 through the first opto-isolation device 421, so as to respectively control the voltage value and current value output by the second power conversion module 20, thereby realizing the output of the time-sequence signal.

[0068] The second power conversion module 20 is an AC / DC adjustable power supply for power supply for time-sequence output. Specifically, under the control of the second processor 41, the output voltage of the second power conversion module 20 can be 0 to 36V, and the output current can be 0 to 50A.

[0069] Referring to Figure 4 , the adjustment unit 42 further includes a relay 424. The relay 424 is connected to the analog output terminals of the second digital-to-analog conversion chip 422 and the third digital-to-analog conversion chip 423, and the relay 424 is set to conduct or disconnect the analog output terminals of the second digital-to-analog conversion chip 422 and the third digital-to-analog conversion chip 423 under the action of the second processor 41.

[0070] Understandably, since the analog output terminal of the second digital-to-analog conversion chip 422 and the analog output terminal of the third digital-to-analog conversion chip 423 can be controlled by the relay 424 to be turned on or off, and the output of the second power conversion module 20 is turned off after they are turned on, which can be used as a protection measure for controlling the timing output.

[0071] Therefore, in this application, based on the setting of the relay 424, there are a total of 3 protection measures for the timing signal output in this application. Therefore, if it is necessary to implement the firing test of the explosive device 300 to be detected, first, the second processor 41 needs to control the relay 424 to be turned off. Secondly, the second processor 41 outputs an analog quantity to adjust the output voltage and current of the second power conversion module 20. Then, the second processor 41 controls the voltage signal transmission unit 43 to load a timing signal (i.e., the target voltage output by the second power conversion module 20) to the explosive device 300 to be detected, thereby improving the detection protection of the explosive device 300 to be detected and the safety protection of the operator.

[0072] Refer to Figure 4 , each voltage signal transmission unit 43 includes an optocoupler 431 and a POMS tube 432. Among them, the optocoupler 431 and the POMS tube 432 are arranged in one-to-one correspondence.

[0073] The optocoupler 431 is connected to the second processor 41, and the POMS tube 432 is connected to the optocoupler 431 and is used to be connected to the corresponding explosive device 300 to be detected. The second processor 41 controls the POMS tube 432 to load the target voltage output by the second power conversion module 20 to the explosive device 300 to be detected through the optocoupler 431.

[0074] Specifically, the voltage signal transmission unit 43 can be one or more. Exemplarily, if the voltage signal transmission unit 43 is 8, then both the optocoupler 431 and the POMS tube 432 are 8. That is, the second processor 41 controls 8 POMS tubes 432 to be turned on simultaneously or in batches according to the timing requirements through 8 optocouplers 431, and when the corresponding POMS tube 432 is turned on, the target voltage output by the second power conversion module 20 is loaded to the explosive device 300 connected to it, thereby realizing the firing test and the opening of the safety mechanism, fuse device, and electromagnetic pin, etc.

[0075] Refer to Figure 4 , the timing signal acquisition unit 44 includes a second opto-isolation device 441, a second analog-to-digital conversion chip 442, and at least one timing signal acquisition circuit 443.

[0076] The second optoelectronic isolation device 441 can be connected to the second processor 41 through the SPI communication protocol. The second analog-to-digital conversion chip 442 is connected to the second optoelectronic isolation device 441. Each timing signal acquisition circuit 443 is connected to the second analog-to-digital conversion chip 442 and a corresponding initiating explosive device 300 to be detected.

[0077] Among them, the second processor is used to control the second analog-to-digital conversion chip 442 through the second optoelectronic isolation device 441, and each timing signal acquisition circuit 443 is used to send the voltage across the corresponding initiating explosive device 300 to be detected, which is collected, to the second processor 41 through the second analog-to-digital conversion chip 442 and the second optoelectronic isolation device 441.

[0078] In this embodiment, the voltage output is realized through the voltage signal transmission unit 43, and the voltage across each corresponding initiating explosive device 300 to be detected is collected through each timing signal acquisition circuit 443, so as to realize the measurement of the voltage applied to the initiating explosive device 300 to be detected, and it is converted into a current value by the second processor 41, thereby realizing the output and acquisition of timing signals. Therefore, by limiting the output current of the initiating explosive device 300 to be detected and the duration of the transmission voltage of the voltage signal transmission unit 43, the non-firing condition of the initiating explosive device 300 to be detected under the safe current condition can be tested to ensure that the initiating explosive device 300 to be detected cannot fire within a certain safe current and a fixed time period.

[0079] Referring to Figure 4 , the timing inspection module 40 further includes a second DC / DC conversion unit 45. The second DC / DC conversion unit 45 is connected to the first power conversion module 10 and is used to convert the voltage at the output end of the first power conversion module 10 to supply power to the second processor 41.

[0080] It can be understood that the intelligent safety type initiating explosive device detection device 100 of the embodiment of the present application integrates a resistance measurement module 30 and a timing inspection module 40. The timing inspection module 40 has a timing output function, thereby improving the efficiency of the firing inspection in batch sampling inspection. There is no need to transfer to other places to use special dedicated equipment, and this one intelligent safety type initiating explosive device detection device 100 can complete the test and firing inspection work. Since the failure to meet the safe current index will also cause initiating explosive device accidents, therefore, realizing the inspection of applying a certain current and a fixed time period to test that the initiating explosive device cannot fire is also an important performance test function. For the time synchronization function of the timing inspection module 40, it can completely record the whole process operation conditions of the initiating explosive device firing inspection and the safe current inspection. This function provides a time reference and improves the accuracy and convenience of time recording.

[0081] Continuing to refer to Figure 1, the intelligent and safe initiator detection device 100 according to the embodiment of the present application further includes a safety box 60. The safety box 60 belongs to explosion-proof, sound-insulating and fire-proof facilities, and is used to install and place the initiator 300 to be detected. The safety box 60 has dust-proof ventilation holes on the side. The safety box 60 can be connected to the resistance measurement module 30 and the timing inspection module 40 through test cables, and is connected to the interface end of the initiator 300 to be detected through internal cables, so that the resistance of the initiator 300 to be detected can be tested and the ignition inspection can be carried out. Moreover, when the ignition inspection is successful, a slight blasting sound can be heard inside, and then the safety box 60 can be opened to check the ignition condition of the initiator.

[0082] Continue to refer to Figure 1 , the intelligent and safe initiator detection device 100 according to the embodiment of the present application further includes a start switch 70. The start switch 70 is arranged between the first power conversion module 10 and the second power conversion module 20 and the external power supply 200, and is used to control the power-on of the first power conversion module 10 and the second power conversion module 20, so as to realize the power-on of the internal control power supply and the condition for the output of the timing power supply.

[0083] Continue to refer to Figure 1 , the intelligent and safe initiator detection device 100 according to the embodiment of the present application further includes auxiliary controls 80. The auxiliary controls 80 include but are not limited to a display 81, a mouse 82, a keyboard 83 and a scanning and printing all-in-one machine 84.

[0084] The control module 50 can be a computer with a dedicated initiator detector software built in. The display 81 is used for the operation and display of the dedicated initiator detector software, and can realize the control and information acquisition of the resistance measurement module 30 and the timing inspection module 40 and display. Moreover, through the dedicated initiator detector software, the timing inspection signal curve graphs loaded simultaneously or classified and time-sharing can be drawn and displayed in real time.

[0085] The mouse 82 and the keyboard 83 are used for the input of human-computer interaction information and can operate the dedicated initiator detector software built in the control module 50.

[0086] The scanning and printing all-in-one machine 84 is used for inputting the incoming factory information of the initiator 300 to be detected and generating the outgoing factory quality report after the detection, etc., so as to overcome the problems of low informatization level and inconvenient output of detection results in the existing initiator detection process.

[0087] Therefore, when using the intelligent safety type initiator explosive detection device 100 of the embodiments of the present application for mass detection of initiator explosives, the production efficiency can be significantly improved, the informatization level in the process of initiator explosive detection management is increased, and it is convenient for transmission and can be stored in large quantities for a long time. By taking informatization measures, human errors are moderately reduced. Moreover, by adopting the detection method of using the resistance value measurement module 30 to detect multiple paths of resistance and the timing inspection module 40 to adjustably output timing, more types of initiator explosives can be adapted, and multiple paths can be detected simultaneously, thereby improving the detection efficiency. At the same time, the intelligent safety type initiator explosive detection device 100 of the embodiments of the present application adopts but is not limited to safety measures such as setting the safety box 60 and / or the start switch 70, voltage limiting, current limiting, safety grounding, the working indicator light L1, the alarm indicator light L2, etc., thereby increasing the protection for initiator explosive detection and the safety protection for operators.
