Description

Technical Field

[0001] The invention belongs to the technical field of civilian blasting materials, and in particular relates to a split type wireless electronic detonator initiation system. Background Art

[0002] Based on some drawbacks of existing wired digital electronic detonators, such as complex implementation, i.e., the need to clamp the foot wire and pull the busbar, and the inability to increase the load capacity, wireless electronic detonators have been developed. Split wireless electronic detonators refer to wireless electronic detonators that are divided into two parts. The first part is a wireless electronic receiver, which is responsible for power supply and wireless signal processing. After the first part is powered on, the second part has not yet been powered on. The second part is the ignition module, and the three codes of the detonator are written in the ignition module. The first part is connected to the second part by a wire. The wireless receiver also has a unique ID, and also has the ignition module required for the QR code ID sticker. Like ordinary wired electronic detonator modules, it has data such as shell code, UID, password, etc.

[0003] The invention patent with the publication number of "CN 114136162 A" and the patent name of "A Wireless Detonation Control System" has a wireless detonator composed of a single-chip microcomputer and a wireless module, which is complex to implement. The repeater in the technical solution of this patent uses a receiving module and a transmitting module, which cannot actually achieve a two-way connection. Two modules that support receiving and transmitting are required, and in order to prevent the data from being forwarded infinitely back and forth, the two modules that support receiving and transmitting of the relay need to be configured as different communication channels. In this patent, some hardware indicators of the relay are not specified for the wireless transmission greater than 1 km, such as how many watts of transmission power are required. Since the wireless electronic detonator is a whole, in actual construction, the entire wireless electronic detonator module is buried underground, and after the blasthole is filled with soil, the wireless electronic signal will be completely gone, causing the entire system to fail to work. When the wireless electronic detonator is a whole, the entire wireless module cannot be miniaturized, resulting in all current detonator production equipment, production lines, and blasthole sizes being affected, and existing equipment needs to be modified. The wireless electronic detonator module used uses MCU plus wireless module, which will also increase the cost. Summary of the invention

[0020] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 As shown, the split wireless electronic detonator detonating system of the present invention includes a wireless detonator and one or more split wireless electronic detonators; the wireless detonator is composed of a wireless module and a detonator application for controlling the wireless module, the split wireless electronic detonator includes a wireless receiver and an ignition module, the wireless receiver and the ignition module are connected by wire, and the wireless receiver is connected to the wireless module of the wireless detonator by wireless communication.

[0023] Use the wireless detonator to directly control the split wireless electronic detonator module. This mode can be used in experiments or under safety protection. Set the communication channel of wireless module 1 to the default channel of the wireless receiver through the wireless detonator application.

[0024] In this method, the communication channel of the wireless module 1 is first set to the same channel as that of any receiver.

[0025] In this way, the data path is that the wireless detonator application running in the wireless detonator sends wireless instructions to the wireless module through the serial port. The wireless module 1 sends it wirelessly, so both the wireless receiver 1 and the wireless receiver N can receive it. After receiving the instruction, the wireless receiver will determine whether the command currently sent is for itself, and judge it by the ID in the command. If it is, it will process it and reply. If it is not for itself, it will determine whether it is a command for the ignition module to which it is connected. If it is, it will be transmitted to the connected ignition module. After the ignition module executes the command, it will reply to the wireless receiver, and the wireless receiver will send the result wirelessly. Then the wireless module 1 on the wireless electronic detonator will receive the command and then forward the command to the wireless detonator application for processing. In this way, the interaction of an instruction is completed.

[0026] Example 2

[0027] Combination Figure 2 The split wireless electronic detonator detonating system of the present invention includes a wireless detonator, a wireless repeater and one or more split wireless electronic detonators; the wireless detonator is composed of a wireless module and a detonator application for controlling the wireless module; the wireless repeater includes two wireless modules, the split wireless electronic detonator includes a wireless receiver and an ignition module, the wireless receiver and the ignition module are connected by wire, the two wireless modules of the wireless repeater are different channels, one wireless module in the wireless repeater is connected to the wireless module of the wireless detonator by wireless communication, and the other wireless module in the wireless repeater is connected to the wireless module of the wireless detonator by wireless communication.

[0028] In this mode, the channel of the wireless detonator needs to be the same as the channel setting of the wireless module 2 of the wireless relay, and the channel of the wireless module 3 of the wireless relay is the same as the channel of the wireless receiver of the split wireless electronic detonator. That is, two channels are used in this system. Only in this way can the conflict caused by mutual forwarding be prevented. If it is not set in this way, when the wireless detonator, wireless relay and wireless module are all within the same signal coverage range, the signal sent by the wireless detonator can also be received by the wireless relay and the wireless receiver. The wireless relay also forwards it using the same channel, which will cause the wireless receiver to receive the command again, which will cause an error. Or it is necessary to use a more complex protocol for control, which will lead to unstable and chaotic data transmission. This is also the key to ensuring communication stability in this system.

[0029] In this mode, the wireless relay is placed in an area close to the blasting area to ensure that the wireless module 3 of the wireless relay can stably communicate with all wireless receivers within the effective signal coverage of the wireless receiver. This allows the wireless receiver to communicate effectively with the wireless module 3 of the near-end wireless relay at a low cost without the need for an external amplifier. The wireless relay wireless module 2 and the wireless module 1 of the wireless detonator are used to ensure long-distance communication through high-power, high-power consumption methods. Because the wireless detonator and wireless relay are reusable, the overall construction cost can be effectively saved.

[0030] The data transmission path in this mode is: wireless detonator application → wireless module 2 of wireless relay receives data → internal bus of wireless relay, such as serial port → internal bus of wireless module 3 of wireless relay receives data → wireless module 3 of wireless relay forwards data wirelessly using the channel of wireless receiver → after receiving the data, the wireless receiver judges and processes it in the same way as the above system architecture. The reply path is just the opposite. This completes the interaction of a command.

[0031] Example 3

[0032] Combination Figure 3 The split wireless electronic detonator detonating system of the present invention includes a wireless detonator, multiple wireless repeaters and one or more split wireless electronic detonators; the wireless detonator is composed of a wireless module and a detonator application for controlling the wireless module; the wireless repeater includes two wireless modules, the split wireless electronic detonator includes a wireless receiver and an ignition module, the wireless receiver and the ignition module are connected by wire, the two wireless modules of the wireless repeater are different channels, one wireless module in the first wireless repeater is connected to the wireless module of the wireless detonator by wireless communication, another wireless module of the first wireless repeater is connected to a wireless module in the next wireless repeater by wireless communication, and another wireless module in the last wireless repeater is connected to the wireless module of the wireless detonator by wireless communication.

[0033] When the universal detonator uses a low-power wireless module, two wireless relays are required to achieve long-distance communication.

[0034] In this mode, since the wireless detonator uses low power and cannot achieve long-distance transmission, a wireless relay 1 needs to be placed near the wireless detonator. In this way, the entire system needs to use 3 channels to ensure stable communication and non-interference. The above has explained why this setting is required.

[0035] Wireless module 1 and wireless module 2 are configured to the same channel, such as channel 1, wireless module 3 and wireless module 4 are configured to the same channel, such as channel 2, and wireless module 5 is configured to the same channel as the wireless receiver, such as channel 0. This ensures that when these devices are within the same signal coverage range, there will be no storm or conflict problems caused by the continuous forwarding of data.

[0036] The data transmission path is similar to the above system architecture 2, that is, sending from left to right and replying from right to left.

[0037] In all system architectures, multiple relays can be added to achieve continuous forwarding of data to achieve long-distance or underground mines, or tunnel turns. You only need to configure different channels to prevent conflicts.

[0038] Combination Figure 4 The following example shows a scenario where multiple relays realize signal turning in an underground mine:

[0039] In this case, wireless module 1 and wireless module 2 are configured to the same channel, such as channel 1. Wireless module 3 and wireless module 4 are configured to the same channel, such as channel 2. Wireless module 5 and wireless module 6 are configured to the same channel, such as channel 3. Wireless module 7 is configured to the same channel as the wireless receiver, which can be channel 0.

[0040] Of course, when ensuring that there is no overlap in signal coverage between the relays, the same channel can be reused for interval settings. For example, the wireless detonator uses channel 1 - wireless relay 1 (channel 1, channel 2) - wireless relay 2 (channel 2, channel 1) - wireless relay 3 (channel 1, channel 2) - wireless relay 4 (channel 2, channel 0) - wireless receiver (channel 0). In this way, unlimited levels of relays can be achieved with limited channels. However, this will increase the communication time and can only be used in special occasions.

[0041] In all of this system architecture, the transmission power used by the wireless module that communicates with the wireless receiver is much greater than that of the wireless receiver. To ensure that when the wireless module can receive the signal from the wireless receiver, since the transmission power of the wireless module is much greater than the power of the wireless receiver, it can more effectively ensure that the command issued by the wireless module can be accurately received by the wireless receiver. That is, the power used by the wireless module that communicates with the wireless receiver in this system is not equal to the power of the wireless receiver. This is also the key to ensuring communication stability in this system.

[0042] In all system architectures, data paths are encrypted using software encryption algorithms to ensure communication security.

[0043] The entire system of the present invention includes a wireless detonator, zero or more wireless relays, and one or more split wireless electronic detonators. The entire system uses Sub-G communication, but is not limited to it. It can also be other wireless communication methods, using a customized communication protocol. All devices in the entire system preferably use the same wireless communication function to reduce the mutual conversion of different wireless transmissions, which leads to increased complexity of the entire system and reduced stability. The communication frequency uses a common frequency band range. The current system verification uses 434MHz, but the present invention is not limited to this specific frequency. The wireless signal modulation method preferably uses GFSK2, but is not limited to it.

[0044] like Figure 5 As shown, the wireless detonator has a detonator control program, a scanning head, can perform Sub-G communication, can configure communication channels, and supports at least one channel. The wireless detonator only needs to have Sub-G communication or the wireless communication function currently used by the entire system.

[0045] like Figure 6 As shown, the wireless relay has two wireless transceiver modules, and the two transceiver modules are configured as different channels to forward data from one channel to another. And there will be no network storm problems caused by the problem of forwarding data back and forth. The wireless relay has a built-in battery, a voltage detection function, a physical power on and off switch, and a power indicator. It supports multiple channels and supports remote channel configuration. To achieve stable transmission of more than 500 meters in various complex environments, all wireless modules must use a transmission power greater than or equal to 3W. Its main function is to send the data received by the wireless detonator card 1 channel to the wireless module 2 through the serial port, and the wireless module 2 then sends it out through its own channel, which is different from the channel of the wireless module 1. When the wireless module 2 receives data from its own channel, it sends it to the wireless module 1 through the serial port, and the wireless module 1 sends it out through its own channel. To realize the data relay forwarding function. Note that as mentioned above, the two cards are running on different channels.

[0046] like Figure 7As shown, the split wireless electronic detonator has two parts, one is a wireless receiver and the other is an ignition module. The two parts are connected by wire. The ignition module is powered by the wireless receiver. The wireless receiver is placed on the ground or at the blasthole. 1. It can solve the signal reception problem of burying the entire receiver and ignition module underground. 2. It can effectively reduce the size of the ignition module to the same size as the existing digital electronic detonator, which will enable the existing detonator module manufacturers to produce wireless ignition modules without modifying the production line. It can also keep the existing filling mechanism unchanged. The wireless receiver has a battery, a primary physical switch, and an electronic switch that supports receiving wireless commands to open and close the electronic switch. It can optionally have two indicator lights. Indicator light 1 is a working indicator light, and indicator light 2 is an indicator light for the power supply status of the ignition module. Each wireless receiver has a unique ID. Considering the cost and battery capacity of the wireless receiver, the internal operational amplifier of the SOC wireless chip used by the wireless receiver, that is, the transmission power is about 0.2W. Under the condition of cost control, it is optional to add a low-power PA, such as a 0.5W or 1W op amp. This will increase the communication distance of the wireless receiver. After the primary physical switch is turned on, the wireless receiver will enter the working state, and the working indicator light will light up. At this time, the ignition module is still not powered. At this time, the ignition module and the wireless receiver can be connected to ensure the safety of the construction. After the construction is completed, the construction personnel will move away from the blasting area to the safe area, and then control the wireless detonator to turn on the electronic switch. The wireless receiver will provide a working voltage higher than the ignition module required to the ignition module. Considering the length of the connecting line, the receiver output can be adjusted to be higher than the working voltage of the ignition module. The current system outputs 8V, but not limited to. The voltage provided by the wireless receiver to the ignition module is adjustable and can be adjusted by sending instructions from the wireless detonator. After the ignition module is powered on, it will perform self-testing to detect whether its own ignition element resistance, energy storage capacitor capacity, charging function, and discharge function are normal. After the self-test is completed, the results of the self-test are saved. And report its own tube shell code, UID, and self-test results to the wireless receiver. The wireless receiver receives this information and saves it. The ignition module has a power-on self-test function, which can detect the resistance of the ignition element, the capacity of the energy storage capacitor, the charging function, and whether the discharge function is normal. It can also detect the voltage on the energy storage capacitor. The ignition module has a unique ID-shell code and UID, which conforms to the standard of digital electronic detonators and has a detonation password detection function.

[0047] The whole system includes two types of commands, a wireless broadcast command and a roll call communication command. When a wireless broadcast command is sent out, all wireless receivers within the signal range will process it. For the roll call communication command, the command contains the identification ID of the wireless receiver, and it will only be processed when the wireless receiver with the corresponding identification ID receives it. In order to ensure the stability of the wireless command of communication, the broadcast command mentioned in the current document will be sent repeatedly for multiple times without reply, preferably 20 times, but not limited to. For the roll call communication command, all commands are with the identification ID of the wireless receiver or with the identification ID of the ignition module. All these commands have replies, that is, the command execution is guaranteed to be normal only when the reply is received. A timer will be started at the beginning of each command execution. Different timing times will be set according to the time required for different command executions. If no reply is received within the specified time, the command will be considered to have timed out, and will be retried and executed again. When the number of retries reaches the specified number and still times out, the command execution fails and the user is informed.

[0048] Safe construction steps for split wireless electronic detonators:

[0049] (1) The ignition module without the wireless receiver is inserted into the explosive package. At this time, the ignition module is not powered and the processing is essentially complete. To ensure construction safety. To ensure the normal function of the ignition module, a functional test can be performed before. This step is the same as the current wired digital electronic detonator. This avoids the phenomenon of inserting the explosive package, burying it, and then detecting abnormalities and reworking.

[0050] (2) The powder bag is placed in the blast hole and the mouth is filled. After all the blast holes are loaded with powder.

[0051] (3) Open the wireless detonator (or wireless registrar) and enter the wireless registration interface.

[0052] (4) Turn on the power of a wireless receiver. At this time, automatic wireless induction registration will be performed, and the delay and position will be generated according to the configured delay rules and positions. Confirm that the indicator light 2 that powers the ignition module is not on, that is, the receiver has not turned on the power supply to the ignition module. Connect the ignition module and the wireless receiver. There is no fixed matching requirement for the receiver and the ignition module here. They can be matched randomly and replaced at any time, which greatly improves the convenience and efficiency of construction. Wireless induction registration effectively solves the following disadvantages of the currently widely used scanning code registration: 1) Scanning code is affected by light. If the light is too dark or too bright, it will affect the result of scanning code, resulting in multiple scanning and failure to scan. Thereby delaying the construction time. 2) During construction, the QR code on the foot line is easy to occupy mud or dirt, which will also cause scanning failure. 3) Some two-dimensional printing or laser engraving is poor, resulting in scanning failure. 4) Scanning code requires one device to align the two-dimensional one by one. When the number is large, the work intensity is also relatively large. 5) When multiple foot lines are together, you may want to scan the code on foot line A, but end up scanning the QR code on nearby foot line B, which requires you to delete the code and scan again.

[0053] If you do not want to use wireless registration scanning, you can skip step 3. After all installations are completed, you can use the QR code scanning method to scan the QR code on the wireless receiver.

[0054] (5) Use a tripod or other fixing method to place the repeater at a closer distance and turn on the repeater power.

[0055] (6) Use the wireless detonator to perform network detection and detonation operations at a long distance.

[0056] Single-shot detection process of wireless receiver:

[0057] 1. Enter the wireless receiver single-shot detection interface in the detonator application and turn on the wireless signal receiving status;

[0058] 2. Turn on the power switch of the wireless receiver of the split wireless electronic detonator;

[0059] 3. After the wireless receiver of the split wireless electronic detonator is powered on, it will detect its own status. After the detection is completed, it will send a data packet containing its own ID and status. Its self-detection information includes battery power, boost function, buck function, etc.

[0060] 4. After the wireless detonator receives the data, it transmits it to the detonator application to parse the data packet, and displays it to the user based on the ID and status of the parsed wireless receiver.

[0061] Ignition module single shot detection process:

[0062] 1. Enter the ignition module single-shot detection interface in the detonator application and turn on the wireless signal receiving state;

[0063] 2. Turn on the power switch of the wireless receiver of the split wireless electronic detonator;

[0064] 3. After the wireless receiver of the split wireless electronic detonator is powered on, it detects its own status. After the detection is completed, it sends a data packet containing its own ID and status;

[0065] 4. After receiving the data packet, the wireless detonator transmits it to the detonator application to parse the data packet, and records the ID of the wireless receiver according to the parsed ID of the wireless receiver;

[0066] 5. Send a command to turn on the power supply of the ignition module to the wireless receiver ID. If the ignition module is already connected, the ignition module will perform a self-detection after powering on. After completion, the self-detection status will be sent to the receiver;

[0067] 6. According to the self-detection time of the ignition module, preferably wait for 500ms, send a command to obtain the connection information of the ignition module to the recorded wireless receiver ID, and wirelessly receive the information of the connection ignition module, including the ID of the ignition module, the capacity of the storage element, whether the charging function is normal, whether the discharging function is normal, whether the ignition element is normal, etc.;

[0068] 7. After receiving the reply, the detonator application parses the command and displays it to the user. At the same time, it compares it with the set threshold and prompts the user whether a certain function is normal. For example, if the storage element capacity is less than 55uf, it prompts that the storage element capacity is too low;

[0069] 8. If it is a continuous detection, you can disconnect the current ignition module from the recorded wireless receiver, and replace a new ignition module with the recorded wireless receiver. The new ignition module will be powered on for self-detection and send the self-detection status of the new ignition module to the receiver. At this time, the detonator application will time 500ms and send a command to obtain the connection ignition module information to the recorded wireless receiver ID. When the new ignition module is replaced, the information obtained again is also updated, and the status of the new ignition module is obtained.

[0070] The current process can also be changed to easily replace the wireless receiver and ignition module each time to realize the single-shot detection function.

[0071] Wireless induction registration method:

[0072] 1. Enter the registration interface of the detonator application and turn on the wireless signal reception status;

[0073] 2. Turn on the power switch of the wireless receiver of the split wireless electronic detonator;

[0074] 3. After the wireless receiver of the split wireless electronic detonator is powered on, it detects its own status. After the detection is completed, it sends a data packet containing its own ID and status;

[0075] 4. After the wireless detonator receives the data, it transmits it to the detonator application to parse the data packet. According to the parsed wireless receiver ID, it determines whether it has been added and gives corresponding prompts;

[0076] 5. Register the wireless receivers to be used for this blasting one by one.

[0077] Relay configuration:

[0078] The current system supports the configuration of wireless relays. Turn on the power of the wireless repeater, enter the wireless relay search interface in the detonator application, search for the wireless relay that has been turned on, click the searched item, enter the configuration of this relay, and configure its working channel, communication rate and other parameters. The relay has a configuration saving function. After configuration, turn off the power and then turn it on again, and the last saved configuration will be used.

[0079] Networking process:

[0080] The relay channel can be arranged and configured according to the entire wireless detonation system architecture. If a first-level relay is used, the wireless module on the detonator is configured as channel 1, the first wireless module channel of the wireless relay is configured as channel 1, the second wireless module is configured as channel 0, and the wireless receiver channel is 0.

[0081] 1. Broadcast a command to all wireless receivers to turn off the wireless receivers and power the ignition module.

[0082] 2. It is preferred to wait for 2 seconds, which can be adjusted according to the characteristics of the ignition module.

[0083] 3. Use the roll call communication command to send networking commands to the wireless receivers registered in the current project one by one, so that the corresponding wireless receivers can enter the same network. Of course, the roll call communication commands here are all in line with the processing logic of the roll call communication commands in the wireless command type mentioned above. After the first round of sending networking commands to the wireless receivers registered in the current project one by one is completed, if there are still commands that time out, the networking commands will be sent one by one to these timed wireless receivers. Preferably, a total of three rounds will be carried out. If there are still failures, prompts will be given and the user will be informed. This is also the key to ensuring communication stability in this system.

[0084] 4. During the process of sending networking commands, an intelligent algorithm will be used to analyze the signal quality of the communication. When poor signal quality is detected or communication is unsuccessful, the user will be prompted to shorten the distance from the wireless receiver.

[0085] 5. Use the roll call communication command to send the ignition module power supply command to the wireless receivers registered in the current project one by one. Of course, the roll call communication commands here are all in line with the processing logic of the roll call communication commands in the wireless command type mentioned above.

[0086] 6. After the first round of sending the ignition module power supply command to the wireless receivers registered in the current project one by one, if there are still commands that time out, the ignition module power supply command will be sent to these wireless receivers that have timed out one by one. Preferably, there will be three rounds in total. If there are still failures, prompt and inform the user. This is also the key to ensuring communication stability in this system.

[0087] 7. After the wireless receiver supplies power to the ignition module, the ignition module will perform a power-on self-test. The contents of the self-test include the discharge function, charging function, energy storage component capacity, ignition component resistance, etc. When the self-test is completed, the self-test result and its shell code and UID information will be sent to the wireless receiver, which will save them. At this time, the wireless receiver will know the information and status of the ignition module to which it is connected.

[0088] 8. Use the roll call communication command to send the wireless receiver connection ignition module information command to the wireless receivers registered in the current project one by one. Record them one by one, so that you can know the tube shell code and self-detection information of the ignition module corresponding to the registered wireless receiver. When the wireless detonator application receives this information, it processes and judges the status, and classifies and counts this information. For example, if the battery voltage is lower than the specified value, it is marked as low battery voltage. When the energy storage element capacity is less than the specified value, it is marked as low energy storage element capacity. When it is greater than the specified threshold, it is marked as too high energy storage element capacity. When the discharge function is abnormal, it is marked as abnormal discharge function. And at the same time, like the roll call power-on command, when there is a wireless receiver that fails to time out in the first round, the second and third rounds of attempts will be carried out. Finally, the classified statistical results are displayed to the user, such as how many are low-power, how many are abnormal in discharge function, how many are abnormal in storage element capacity, etc. Click the corresponding entry to display detailed list information, showing which wireless receivers have current faults.

[0089] 9. Use the roll call communication command to send the write delay command to the wireless ignition modules registered in the current project one by one. If the first round fails, multiple rounds of attempts will be made to ensure that the first shot is written successfully and accurately. The wireless receiver receives the command and sends it to the ignition module. The ignition module will determine whether it is its own shell code. If it is, it will execute the delay setting, otherwise it will not process it.

[0090] Detonation process:

[0091] When all registered wireless electronic detonators are successfully networked, the system will detect whether the safety switch is on. If it is on, the user will be prompted to confirm whether to enter the detonation process. If it is not on, the user will be prompted to turn on the safety switch. After turning on the safety switch, the user will be prompted to confirm whether to enter the detonation process.

[0092] The detonation process is as follows:

[0093] 1. Use the roll call communication command to send the detonation preparation command to the ignition modules registered in the current project one by one. The current command contains the password of the ignition module, the shell code of the ignition module, and the voltage to be charged, etc.

[0094] 2. After the wireless receiver receives the blasting preparation command, it will send it to the connected module. The module will determine whether it is its own tube shell code. If it is, it will compare whether the password is correct. If it is correct, it will charge to the specified voltage. If the password is incorrect, it will feedback that the password is wrong. If the password is correct, but the specified voltage is not charged within the specified time, it will feedback that the charging is abnormal and inform the current voltage value of the storage element.

[0095] 3. As with all the above processes, when the first round of communication fails, a second round of communication will be conducted for the failed part. Preferably, a total of 3 rounds of communication will be conducted. The detonator application will record and count the returned results. In the case of failure, the user can click on the corresponding category to view the ignition module abnormalities and the reasons for the abnormalities. This will allow construction personnel to quickly locate the abnormal module.

[0096] 4. After all registered ignition modules are charged, the detonation control interface is entered, prompting the user to press and hold two detonation keys for 5 seconds to send a broadcast detonation command. When the user presses both keys at the same time, the user interface will count down. During the countdown, the user can release one of them at any time to cancel the detonation.

[0097] 5. When the user exits the detonation interface, a broadcast discharge command will be sent to discharge the stored energy charge on the charging ignition module.

[0098] The networking and detonation process commands used by the current system are extremely concise. On the one hand, they reduce the number of wireless command transmissions, which can increase stability, while also speeding up the speed of networking and detonation, effectively improving construction efficiency.
