[0019] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all couplings of one or more related listed items.

[0021] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0022] At present, when a digital electronic detonator control module is subjected to an ignition sensitivity test, a staff member is required to connect the digital electronic detonator control module to the test ignition head one by one, and then start the ignition sensitivity test. After the test, the digital electronic control module is separated from the corresponding test ignition head one by one, thereby completing the ignition sensitivity test of the digital electronic detonator control module. This ignition sensitivity test method is inefficient.

[0023] like Figure 1 As shown, the present application provides a digital electronic detonator control module ignition sensitivity test device, including a housing 1, a control module socket 2, a connecting portion 3 and a circuit board 4.

[0024] The housing 1 is a rectangular parallelepiped, and heat dissipation holes 5 are provided on the side of the housing 1 for dissipating heat inside.

[0025] A control module socket 2 is provided with a socket 16 fixed to a digital electronic detonator. There are multiple control module sockets 2, so that the control module socket 2 can be plugged and fixed to a digital electronic detonator row 7 composed of multiple digital electronic detonators. The control module sockets 2 are evenly arranged on the circuit board 4 along the length direction of the shell 1, and can also be directly arranged on the shell 1 as needed; although multiple control module sockets 2 are connected to the circuit board 4, each control module socket 2 can be connected to the probe 6 separately, that is, each control module socket 2 can be measured separately, and the data are summarized on the circuit board 4 and sent using the circuit board 4.

[0026] The connecting portion 3 is arranged in the housing 1 , and a plurality of probes 6 are arranged on the connecting portion 3 , and the probes 6 are connected to the control module sockets 2 in a one-to-one correspondence.

[0027] The circuit board 4 is arranged in the housing 1 and connected to the control module socket 2. It has a power supply communication interface 20 and a signal transmission interface 21. The power supply communication interface 20 is used to receive test instructions, and the signal transmission interface 21 is used to send test results to a designated device. The circuit board 4 is a conventional PCB board, and each control module socket 2 thereon is an independent circuit. In this way, it can be ensured that each control module socket 2 performs the test task independently. The circuit board 4 can also be used to send signals to multiple control module sockets 2 at the same time so that multiple control module sockets 2 work at the same time. The circuit board 4 only plays the role of signal transmission and circulation, and does not process the signal. Even if it is processed, it is conventional processing. This application does not involve software improvements.

[0028] The connection portion 3 and the inner wall of the housing 1 are used to accommodate a row of ignition heads 8; when the row of ignition heads 8 is placed in the accommodation space, each ignition head in the row of ignition heads 8 is electrically connected to the corresponding probe 6. The row of ignition heads 8 represents a plurality of ignition heads connected as a whole through a connecting plate.

[0029] It should be noted that the control module socket 2, the digital electronic detonator, the probe 6, and the ignition head correspond to each other one by one, forming a structure for testing one digital electronic detonator.

[0030] In one embodiment, a plurality of test trigger buttons 9 are disposed on the top surface of the housing 1 , and the test trigger buttons 9 are correspondingly connected to the control module sockets 2 .

[0031] It should be noted that the test trigger button 9 corresponds to a structure for testing one digital electronic detonator, and the test trigger button 9 can be understood as a test switch. When the test switch is turned on, the digital electronic detonator can be tested. When the test trigger button 9 is working, the control module socket 2 is energized, and the digital electronic detonator and the ignition head are connected through the probe 6 to form a path for testing the digital electronic detonator.

[0032] In addition, in order to facilitate the replacement of the digital electronic detonator row 7, a cover plate 10 is provided on the back of the shell 1, and one end of the cover plate 10 is connected to the shell 1 by a hinge. In this way, after opening the cover plate 10, the digital electronic detonator row 7 in the shell 1 can be replaced and tested.

[0033] In one embodiment, the connecting portion 3 divides the shell 1 into two spaces, namely a first accommodating space 11 and a second accommodating space 12, wherein the first accommodating space 11 accommodates the circuit board 4 and the control module socket 2; the second accommodating space 12 can accommodate the ignition head row 8, and the probe 6 is located in the second accommodating space 12 and protrudes from the connecting portion 3.

[0034] Specifically, the connection part 3 and the housing 1 may be a separate structure or an integrated structure. The following is an exemplary description of the connection part 3 and the housing 1 being an integrated structure.

[0035] The connecting portion 3 divides the shell 1 into two spaces, namely a first accommodating space 11 and a second accommodating space 12. The first accommodating space 11 is for accommodating the circuit board 4, the control module socket 2, etc., and the second accommodating space 12 is an "L"-shaped open space, which is convenient for installing the ignition head row 8. In addition, the probe 6 is located on the outer wall of the connecting portion 3 in the second accommodating space 12 and is evenly distributed along the length direction of the outer wall of the connecting portion 3. The position of the probe 6 corresponds to the position of the control module socket 2 in the first accommodating space 11.

[0036] In one embodiment, the probe 6 is a retractable detection needle; a plug-in portion 13 is provided on the side of the connecting portion 3 facing away from the control module socket 2, the interior of the plug-in portion 13 is hollow, and a notch is provided on the side adjacent to the probe 6, and a strip-shaped positioning hole 14 is provided on the top of the plug-in portion 13; wherein, when the ignition head row 8 is inserted into the strip-shaped positioning hole 14 from the top of the plug-in portion 13, the trigger point of the ignition head row 8 is opposite to the probe 6; when the plug-in portion 13 abuts against the connecting portion 3, the trigger point of the ignition head row 8 is electrically abutted against the probe 6.

[0037] Specifically, when the second accommodating space 12 is an "L"-shaped structure, a plug-in portion 13 is provided on the side of the connecting portion 3 away from the control module socket 2. The inner part of the plug-in portion 13 is hollow, and the notch provided on the side adjacent to the probe 6 can be a strip-shaped notch, or a plurality of holes capable of accommodating the insertion of the probe 6. In this way, when the plug-in portion 13 moves toward the connecting portion 3, the probe 6 can be inserted into the plug-in portion 13 and contact the trigger point of the ignition head of the ignition head row 8 in the plug-in portion 13, thereby completing the electrical connection between the digital electronic detonator, the probe 6 and the ignition head.

[0038] It should be noted that a strip-shaped positioning hole 14 is provided at the top of the plug-in portion 13, and the strip-shaped positioning hole 14 is arranged along the length direction of the plug-in portion 13, so that the ignition head row 8 can be just inserted into the plug-in portion 13 from top to bottom along the strip-shaped positioning hole 14. After the ignition head row 8 is partially inserted into the strip-shaped positioning hole 14, the trigger point of the ignition head row 8 is opposite to the probe 6. When the plug-in portion 13 is in contact with the connecting portion 3, the trigger point of the ignition head row 8 can push back part of the probe 6, thereby ensuring close contact between the trigger point and the probe 6.

[0039] In addition, a digital electronic detonator control module ignition sensitivity test device also includes an ejector rod 15, one end of the ejector rod 15 is fixedly connected to the connecting part 3, and the other end is inserted into the plug-in part 13, and the end surface area is larger than the cross-sectional area of ​​the rod wall, and a spring is provided on the ejector rod 15 between the connecting part 3 and the plug-in part 13; or, one end of the ejector rod 15 is fixedly connected to the plug-in part 13, and the other end is inserted into the connecting part 3, and the end surface area is larger than the cross-sectional area of ​​the rod wall, and a spring is provided on the ejector rod 15 between the connecting part 3 and the plug-in part 13; or, one end of the ejector rod 15 is fixedly connected to the connecting part 3, and the other end is inserted into the plug-in part 13, and the end surface area is larger than the cross-sectional area of ​​the rod wall, and a spring is provided on the rod wall of the ejector rod 15 inserted between one end of the plug-in part 13 and the inner wall of the plug-in part 13.

[0040] It should be noted that when one end of the ejector rod 15 is fixedly connected to the connecting portion 3, the ejector rod 15 can be in the shape of a flat pin. In this way, when a spring is provided on the ejector rod 15 between the plug-in portion 13 and the connecting portion 3, the spring will push the plug-in portion 13 in a direction away from the connecting portion 3. However, since the end surface of the flat pin can form a limit to the plug-in portion 13, the ejector rod 15 limits the maximum distance of movement of the plug-in portion 13. Under this distance, the probe 6 can be reset, and when the ignition head row 8 is inserted into the plug-in portion 13, the ignition head row 8 will not contact the probe 6, that is, the ignition head row 8 and the probe 6 are in a separated state. The situation in which one end of the ejector rod 15 is fixedly connected to the plug-in portion 13 and the other end is inserted into the connecting portion 3 is opposite to the situation in which one end of the ejector rod 15 is fixedly connected to the connecting portion 3 and the other end is inserted into the plug-in portion 13, and the ejector rod 15 with one end inserted into the plug-in portion 13 is in the opposite direction, which will not be described in detail here. When the spring is arranged between the connecting portion 3 and the plug-in portion 13 , it is necessary to provide an inwardly concave groove at the ejection rod 15 corresponding to the connecting portion 3 or the plug-in portion 13 , so as to reserve a space for accommodating the compressed spring.

[0041] In addition, the spring can also be set between the flat head end of the flat head pin and the inner wall of the plug-in part 13 shell. In this case, the spring is in a reset state, the plug-in part 13 is in contact with the connecting part 3, and when the plug-in part 13 is away from the connecting part 3, the spring is in a compressed state.

[0042] It should also be noted that the ejector rod 15 may not be provided with a spring as required, so that the ejector rod 15 can limit the moving direction of the plug-in portion 13 during the movement of the plug-in portion 13. After the plug-in portion 13 is attached to the connecting portion 3, the positioning member 17 is used to position the plug-in portion 13.

[0043] Exemplarily, the end faces at both ends of the length direction of the plug-in portion 13 are provided with insertion holes 16; a positioning member 17 is provided on the shell 1 adjacent to the insertion hole 16 of the connecting portion 3, and the positioning member 17 can move along its length direction; when the positioning member 17 moves relatively, it is inserted into the insertion hole 16 to form a limit for the plug-in portion 13, so as to maintain the abutment between the plug-in portion 13 and the connecting portion 3 and prevent the plug-in portion 13 from moving in a direction away from the connecting portion 3.

[0044] It should be noted that the plug hole 16 can also be understood as a limiting hole of the plug-in part 13. In the above content, the razor plug-in part 13 is ejected by the ejector rod 15. However, if the plug-in part 13 is always in a state of contact with the connecting part 3, it is necessary to limit the plug-in part 13 when the plug-in part 13 and the connecting part 3 are in a state of contact. Therefore, the positioning member 17 is inserted into the plug hole 16 of the plug-in part 13 to form a limit on both ends of the plug-in part 13. The shape of the positioning member 17 may include a sleeve 171 and a telescopic pin 172. The sleeve 171 is fixed to the housing 1 by a locking nut. The telescopic pin 172 is inserted into the sleeve 171 and connected to the sleeve 171 by a positioning spring 173. In this way, the positioning spring 173 provides a reset force for the telescopic pin 172. When the telescopic pin 172 is in a reset state, a portion of the telescopic pin 172 protrudes from the housing 1 and is inserted into the plug hole 16 to limit the plug hole 16. One end of the telescopic pin 172 outside the housing 1 is provided with a convex button 174 for convenient hand holding.

[0045] In one embodiment, a digital electronic detonator control module ignition sensitivity testing device also includes an external positioning member 18, which is arranged on the front side of the shell 1 and is rotatably connected to the front side of the shell 1; a plurality of fins 19 are arranged on one side of the external positioning member 18, and a space for accommodating the ignition head is formed between adjacent fins 19, and the ignition head is blocked.

[0046] Specifically, the external positioning member 18 is connected to the connecting portion 3 of the shell 1 by a hinge, so that the external positioning member 18 can rotate relative to the connecting portion 3. When the external positioning member 18 is rotated to be perpendicular to the connecting portion 3, the multiple fins 19 on the external positioning member 18 are also perpendicular to the connecting portion 3, and the gap between adjacent fins 19 can accommodate the space of the ignition head. That is to say, when the external positioning member 18 is perpendicular to the connecting portion 3, the portion of the ignition head exposed outside the plug-in portion 13 is placed in the gap between adjacent fins 19. In this way, adjacent ignition heads are separated by the fins 19. In this way, when the contact point receives the current transmitted by the probe 6, the current is transmitted to the top of the ignition head to ignite the top, thereby judging the ignition sensitivity of the digital electronic detonator according to the ignition time, and the fins 19 can prevent the flame from spreading to the adjacent ignition heads after the ignition head is ignited.

[0047] In one embodiment, the power supply and communication interface 20 includes a power supply interface and a communication interface, the power supply interface and the communication interface are respectively arranged on one side of the housing 1 , and the signal transmission interface 21 is arranged on a side wall of the housing 1 away from the probe 6 .

[0048] Specifically, the power supply interface supplies power to the components that require electricity in the ignition sensitivity test device of the digital electronic detonator control module. The communication interface is a quick-release BUS interface for receiving communication signals. After receiving the communication signal, the sensitivity test is performed on the digital electronic detonator row 7 placed on the control module socket 2. During the test, the test trigger button 9 is in a triggering or working state. In this way, multiple digital electronic detonators can be tested simultaneously using the communication signal, and the test results are sent to the designated device through the signal sending interface 21, so that the designated device can analyze the sensitivity of the digital electronic detonator. In addition, when the sensitivity of a certain digital electronic detonator is abnormal, the digital electronic detonator can be controlled to work separately by controlling the test trigger button 9. For example, if the sensitivity of the digital electronic detonator at position 2 is abnormal, other test trigger buttons 9 can be turned off. By repeatedly controlling the test trigger button 9 at position 2, it is determined whether the sensitivity of the digital electronic detonator at position 2 is normal.

[0049] The power supply interface and the communication interface may share a common interface, which is not limited in this application. Example

[0050] Preparation stage: First, it is necessary to ensure that all necessary components and equipment are in a usable state, including checking whether the power supply communication interface 20 and the signal transmission interface 21 on the circuit board 4 are working properly, and testing whether the components such as the trigger button 9, the cover plate 10 and the positioning member 17 are intact.

[0051] Installing digital electronic detonators: Open the cover plate 10 on the back of the housing 1, install the digital electronic detonator row 7 on the control module socket 2, and ensure that each detonator is firmly fixed. After the installation is completed, close the cover plate 10 to ensure that the detonator row will not move during the test.

[0052] Install the ignition head row 8: Release the limit of the positioning piece 17 on the plug-in part 13 to move the plug-in part 13 to the farthest distance along the length direction of the ejector rod 15. Next, insert the ignition head row 8 through the top strip-shaped positioning hole 14 of the plug-in part 13 to ensure that the trigger point of the ignition head is opposite to the probe 6.

[0053] Ejector rod 15 limit: When the positioning member 17 is in the state of compression (not limiting the insertion hole 16), the plug-in part 13 is pushed toward the connecting part 3 and abuts against the connecting part 3, and the compression of the positioning member 17 is released, so that the two positioning members 17 move relative to each other and are inserted into the insertion hole 16 on the end face of the plug-in part 13, and the plug-in part 13 is limited so that the plug-in part 13 remains in a state of abutting against the connecting part 3 (it should be noted that the plug-in part 13 may not abut against the connecting part 3 as needed, and it is ensured that the trigger point can compress the probe 6 and the trigger point and the probe 6 are tightly fitted). In this process, the trigger point compresses the probe 6, forming a tight fit between the trigger point and the probe 6, ensuring the smoothness of the circuit.

[0054] Connect the test device: After ensuring that the ignition head row 8 has been completely inserted into the plug-in portion 13 and the positioning member 17 is correctly positioned, check whether the contact between the connecting portion 3 and the plug-in portion 13 is good to ensure that the electrical connection is stable during the test.

[0055] Set the test parameters: The power supply and communication device are connected through the power supply communication interface 20, and the external operating device is used through the power supply communication interface 20. The test instructions are set using the operating device. The operating device can be a computer. This application does not limit the operating device. An operating device that can send a test digital electronic detonator signal is sufficient.

[0056] Trigger test: Operate the test trigger button 9 to start the test program. The circuit board 4 receives the test instruction and sends current to the ignition head row 8 through the probe 6. After the capacitor of the ignition head receives the current, it generates heat and ignites the top of the ignition head. After ignition, a signal is formed and the circuit board 4 sends the signal to the designated device through the signal transmission interface 21. The designated device is a device capable of analyzing sensitivity, such as a computer with sensitivity analysis software. During the ignition head ignition process, the fin 19 acts as a partition to separate adjacent ignition heads to prevent the ignition of the ignition head from being affected by the ignition of the adjacent ignition head.

[0057] Result analysis: Receive and analyze test results on designated equipment to determine whether the ignition sensitivity of each digital electronic detonator meets the standards.

[0058] The various embodiments in the present disclosure are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0059] The protection scope of the present disclosure is not limited to the above-mentioned embodiments. Obviously, those skilled in the art can make various changes and modifications to the present disclosure without departing from the scope and spirit of the present disclosure. If these changes and modifications fall within the scope of the claims of the present disclosure and their equivalents, the intention of the present disclosure also includes these changes and modifications.
