[0002] When the blasting industry implements blasting operations at a blasting site, for large-scale blasting tasks such as mining, building demolition or tunnel excavation, which are carried out in sections or batches, thousands of detonators may need to be detonated simultaneously. With the expansion of the scale and increase in the complexity of blasting operations, the control demand for blasting systems is getting higher and higher.

[0003] The blasting system of the prior art cannot effectively manage the synchronous or sequential detonation of many detonators under large load conditions. The load capacity of a single detonator is limited by its own driving capacity and cannot meet the requirements of the blasting project site. Multiple detonators are required to communicate collaboratively to meet the collaborative blasting engineering tasks of a large number of digital electronic detonators. The existing collaborative communication method of multiple detonators generally adopts a wired communication method. Not only do multiple detonators need to be connected in the form of multiple connectors, but also a large amount of wire wiring work is required. The wiring is complicated in harsh environments and is easily affected by the environment. There are greater operational risks, and there are problems such as low detonation accuracy, poor anti-interference ability, and insufficient safety.

[0023] Existing blasting systems mostly use wired cascade connection of digital electronic detonators. This method requires laying a large number of cables during the operation, which increases the construction difficulty and time cost. Especially in complex terrain or dangerous scenes, the wiring work affects the blasting efficiency and safety. At the same time, the wired connection is easily affected by external factors (such as electromagnetic interference, cable damage, etc.), resulting in signal transmission distortion or delay, and the control accuracy of the blasting process is difficult to guarantee.

[0024] like Figure 1-Figure 4As shown, in this embodiment, a wireless detonator for digital electronic detonators with large load capacity includes: a control mainboard and a detonating card, wherein the control mainboard is composed of a main controller, a memory module, a clock module, a button and a display peripheral circuit; the detonating card is composed of an embedded ARM processor and a processor peripheral clock and a memory circuit, and the detonating card manages the BUS voltage by the voltage management circuit of the BUS bus, and switches the communication voltage and the detonating voltage according to the detonation; the detonating card is also provided with a sampling and measuring circuit of the BUS bus, which is used to monitor the load condition of the digital electronic detonator on the BUS bus in real time, and to monitor the voltage and current on the load network of the digital electronic detonator in real time; the wireless module of the detonating card can realize the sending of detonation control information to the outside world through wireless mode. The sampling and measuring circuit plays a protective role when a short circuit occurs in the load network.

[0025] Specifically, a wireless detonator with a large load capacity of digital electronic detonators is composed of a control mainboard and a detonating card. The battery of the wireless detonator supplies power to these two parts, and the Android system manages the battery power through a power management module. The control mainboard is composed of a main controller and peripheral circuits such as memory, clock, button, and display screen. The detonating card is composed of an embedded ARM processor and processor peripheral circuits such as a processor peripheral clock and memory. The BUS bus voltage management circuit on the detonating card manages the BUS voltage of the wireless detonator, and switches the communication voltage and the detonating voltage according to the needs of the detonation business process; the detonating card has a BUS bus sampling and measurement circuit, which is used to realize real-time monitoring of the load condition of the digital electronic detonator on the BUS bus, and real-time monitoring of the voltage and current on the load network of the digital electronic detonator, so as to truly respond to the status of the digital electronic detonator connected to the load network at each stage of the business process. The detonating card also has a protection circuit while monitoring, which can play a protective role when abnormal conditions such as short circuits occur in the load network. The wireless module on the detonating card can send detonation control information to the outside world through wireless mode.

[0026] In this embodiment, a wireless detonator and detonation method for digital electronic detonators with large load capacity are provided, including: a control mainboard and a detonation card, the control mainboard is composed of a main controller, a memory module, a clock module, a button and a display peripheral circuit; the detonation card is composed of an embedded ARM processor and a processor peripheral clock and a memory circuit, the detonation card manages the BUS voltage by the voltage management circuit of the BUS bus, and switches the communication voltage and the detonation voltage according to the detonation; the detonation card is also provided with a sampling and measurement circuit of the BUS bus, which is used to monitor the load of the digital electronic detonator on the BUS bus in real time, and to monitor the voltage and current on the load network of the digital electronic detonator in real time; the wireless module of the detonation card can realize the sending of detonation control information to the outside world through a wireless mode. The wireless detonator of the digital electronic detonator with large load capacity in the present application has significant advantages over the traditional wired cascade technology in terms of detonation mode, load capacity, safety, environmental adaptability and operation efficiency. It can support larger-scale blasting operations, has higher detonation accuracy and flexibility, and can greatly improve the safety and efficiency of operations, especially in complex and dangerous environments.

[0027] In one embodiment, the sampling and measuring circuit includes multiple ranges. The sampling and measuring circuit switches to a low range when the load is low, and switches to a high range when the load is high by switching a multi-range resistor shunt.

[0028] Specifically, in order to meet the large load requirements of digital electronic detonators, when the detonator is loaded with one or thousands of digital electronic detonators, the current range sampling range of the detonator is between a few uA and tens of mA, and the recognition accuracy of small currents must meet the requirements. The higher the current requirement of a digital electronic detonator, the multi-range sampling design is adopted to address the contradiction between the current range and the recognition accuracy. By switching the multi-range resistor shunt, when the load is low, it can be switched to the low-range mode to improve the accuracy; when the load is high, it can be switched to the high-range mode to adapt to a larger current range. In this way, a wide range of current changes can be covered without affecting the signal sampling accuracy.

[0029] In this embodiment, a detonation method for a wireless detonator with a large load capacity of digital electronic detonators includes: arranging a wireless host in a safe area outside the blasting area to control the operation of the wireless slave through wireless signals, distributing the wireless slaves at various blasting points that need to be controlled in the blasting area, and each wireless slave is used to control multiple digital electronic detonators, wherein the wireless slaves are connected to a corresponding number of digital electronic detonators through blasting area lines; setting the communication parameters of the wireless module such as power, rate and communication main frequency according to the wireless communication distance designed for blasting, and establishing a communication connection between the wireless host and the wireless slave through the wireless module; controlling the load network of the wireless slave Start networking communication, send the delay parameters to each detonator, complete the delay setting of the digital electronic detonator, and ensure that all load network digital electronic detonators are synchronized; the operator can operate the wireless detonator host to send charging instructions to each wireless slave, and the wireless slave starts to provide charging conditions to each load network. After the digital electronic detonator is charged, it can meet the conditions for detonation; when the wireless host issues a detonation command, the detonation command is transmitted to each wireless slave through a wireless signal. After receiving the command, the wireless slave immediately sends a detonation signal to the load network, thereby controlling all load digital electronic detonators to complete detonation according to the delay setting. The wireless host monitors the status of the wireless slave through the sampling and measurement circuit, including: the success or failure of the signal transmission and the detonation status of the digital electronic detonator, to ensure that each link is executed accurately.

[0030] Specifically, the location of the wireless host: The wireless host is usually arranged in a safe area outside the blasting area and is responsible for controlling the operation of the slave machine through wireless signals. The layout location of the host should ensure that the signal covers the entire blasting area and avoids electromagnetic interference on site. Distribution of wireless slaves: According to the blasting design, the wireless slaves are distributed at various blasting points that need to be controlled in the blasting area. Each slave is responsible for controlling multiple digital electronic detonators, so the location of the slave should be reasonably set according to the distribution of the blasting points to ensure stable signal reception. Detonator connection: According to the blasting design, each wireless detonator slave is connected to a corresponding number of digital electronic detonators through the blasting area line, so that the wireless detonator slave receives the control instructions of the wireless detonator host, and then controls the networking, charging, and detonation of the detonators.

[0031] Specifically, after the wireless detonator system is started, the wireless module communication parameters including power, rate and communication main frequency are set according to the wireless communication distance of the blasting design, and the wireless host and slave establish a communication connection through the wireless module. The communication connection should ensure that all slaves can receive the instructions of the host and feedback the current status. The operator can set the mode of the wireless detonator to host mode or slave mode according to the usage scenario of the wireless detonator. First, according to the blasting design in the blasting area, the detonator registration, detonator delay setting, blasting sequence and detonation time setting operations are completed on the slave side with the help of the human-machine interface. After the setting is completed, the network detection on the slave side can be carried out. The user-friendly graphical interface facilitates parameter adjustment. After the network detection is completed, the operator can exit the blasting area.

[0032] Specifically, the operator in the control area can complete the operation by operating the human-machine interface of the wireless detonator host. According to the requirements of the blasting design, the operator can control the wireless detonator slave load network to start networking communication, that is, complete the transmission of delay parameters to each detonator, complete the delay setting of the digital electronic detonator, and ensure the synchronization of all load network digital electronic detonators.

[0033] Specifically, when the networking is completed, the operator can operate the wireless detonator host to send charging instructions to each wireless detonator slave, and each wireless detonator slave begins to provide charging conditions to each load network. After each digital electronic detonator is fully charged, the conditions for detonation are met. When the wireless detonator host issues a detonation command, the detonation command is transmitted to each wireless detonator slave through a wireless signal. After receiving the command, the wireless detonator slave immediately sends a detonation signal to the load network, thereby controlling all load detonators to complete detonation according to the delay setting. During the entire detonation process, the host will continuously monitor the status of the slave, including the success or failure of signal transmission, the detonation status of the detonator, etc., to ensure that each link is executed accurately. If a wireless detonator slave or a connected digital electronic detonator fails during operation, the system will automatically record and issue an alarm, and the operator can take immediate measures.

[0034] Specifically, after the detonation is completed, the wireless detonator host will automatically record the working conditions of each wireless detonator slave and each digital electronic detonator, and generate a blasting report, including the delay and detonation status of each digital electronic detonator, for subsequent analysis. After the blasting is completed, the operator needs to check the status of all equipment to ensure that the wireless detonator slave is not damaged so that it can be used next time.

[0035] Specifically, multiple identity authentication: When operating the wireless detonator, the system will require the operator to perform multiple identity authentication to ensure that only authorized operators can perform the detonation operation. Emergency stop function: If any emergency occurs during the operation, such as signal interference or equipment failure, the system will automatically trigger the emergency stop function to stop the detonation process and ensure on-site safety.

[0036] In one embodiment, the wireless host further includes: dividing the current range under different load conditions into several segments through a sampling measurement circuit, and fitting each segment using a linear function. Dividing the current range under different load conditions into several segments, and fitting each segment using a linear function, includes: Generate multiple linear correction formulas:

[0037] in, and is the fitting coefficient of the i-th segment, is the actual sampled voltage.

[0038] Specifically, in addition to the above hardware methods to improve sampling accuracy, the software design also uses a multi-segment linear fitting digital signal processing algorithm to effectively compensate. According to the current characteristics of each digital electronic detonator, the current range under different load conditions is divided into several segments, and each segment is fitted using a linear function. For each fitting function, find the corresponding segment based on the sampling value, and use the fitting function to correct the current value. When carrying thousands of rounds, the actual measured current may deviate from the true value due to hardware errors, which can be corrected through linear fitting. The corrected value is closer to the actual current. The steps required are: Acquire sampling error data under different current ranges through experiments; Perform linear fitting on each segment of data to generate multiple linear correction formulas; During measurement, the corresponding correction formula is selected for compensation according to the range of the current current value.

[0039] The correction formula is as follows:

[0040] in, and is the fitting coefficient of the i-th segment, is the actual sampled voltage.

[0041] This design can ensure reasonable current sampling accuracy when loading 1 round or thousands of rounds.

[0042] In one embodiment, a wireless host and a wireless slave establish a communication connection through a wireless module, including: using a hash table to map the digital electronic detonator ID into a short bit field, and representing the status information through a bit compression method; when the status information of the digital electronic detonator does not change frequently, only the changed part is transmitted.

[0043] In terms of software design, in view of large load conditions, the maximum capacity of registered digital electronic detonators has been increased from hundreds of rounds to thousands of rounds. In response to this order of magnitude change, the registration table of the wireless detonator has been optimized to improve the efficiency and stability of the system.

[0044] In terms of data structure optimization, a compact data structure is used to reduce memory usage and significantly reduce storage overhead; at the same time, a hierarchical data structure is used. For a large-scale registry, it can be designed as a hierarchical structure. The first layer is used to quickly locate the group or area to which the detonator belongs, and the second layer is used to query the status of a specific detonator.

[0045] In terms of data query, in order to optimize efficiency, a hash table is used to speed up the search speed of the detonator ID. When the number of detonators in the registry increases by an order of magnitude, the linear traversal of the registry will cause the query efficiency to decrease. The hash table method greatly improves the search speed of the detonator ID and improves the overall performance. The design uses a simple and efficient modulus method to map the detonator ID to the hash table. In order to deal with hash conflicts, the design uses a combination of the selection chain address method and the open address method. The chain table is used when there are a small number of conflicts, and the open address method is switched to when there are serious conflicts.

[0046] (3) Optimized wireless communication protocol: Since the wireless detonator based on digital electronic detonators with large load capacity needs to carry the status information of multiple detonators during the wireless communication process, the communication protocol has been streamlined and optimized.

[0047] On the one hand, a hash table is used to map the detonator ID to a short bit field, and the status information is represented by a bit compression method, which reduces the number of communications and improves the response speed of the system.

[0048] On the other hand, differential update: If the state information of the detonator does not change frequently, only the changed part can be transmitted, without transmitting all the state information each time. If the state data of multiple detonators are continuous, differential encoding or run-length encoding (RLE) can be used to represent the difference between the states, so that the state compression method can be used to reduce the transmission of repeated data. Thus, the communication load can be reduced.

[0049] Again, for non-critical status data, a non-confirmation mechanism can be used, while for command and control data that require confirmation, batch confirmation can be used to reduce communication overhead.

[0050] By streamlining and optimizing the data structure, encoding method, communication protocol and confirmation mechanism, the transmission efficiency of wireless communication messages can be significantly improved, and delay and power consumption can be reduced. For wireless detonation systems such as digital electronic detonators, this can save resources and improve the response speed of the system.

[0051] In this embodiment, physical wiring is reduced: The core advantage of the wireless detonator is that it eliminates the traditional wired communication method, greatly reducing the wiring workload and the difficulty of on-site construction. Improved safety: Wireless control remote operation reduces the risk of personnel at the blasting site and improves operational safety. This implementation of the wireless detonator is suitable for a variety of complex blasting environments, especially mining, building demolition or tunnel excavation in large-scale engineering projects, greatly improving operational efficiency and reducing costs.

[0052] 1. Improve blasting efficiency The wireless communication design of the wireless detonator greatly reduces the wiring workload in the traditional wired system, and is particularly suitable for large-scale blasting projects. The elimination of the complex wire wiring process not only reduces the construction difficulty, but also significantly shortens the construction time, thereby improving the overall blasting operation efficiency.

[0053] 2. Reduce construction costs Wireless communication eliminates the need for a large number of physical wires, thereby saving wire procurement and maintenance costs. In addition, the simplified construction process also reduces the time and cost of manual operations, achieving the goal of reducing costs and increasing efficiency.

[0054] 3. Improve blasting accuracy Wireless communication can achieve precise delay control of large-capacity digital electronic detonators, so that they can be detonated on time according to the preset blasting sequence and delay, with control accuracy at the microsecond level. This high control accuracy is particularly important in large and complex blasting tasks, which helps to optimize blasting effects, reduce secondary damage, and ensure construction quality.

[0055] 4. Enhanced security The wireless detonator uses remote operation and wireless communication to avoid direct contact between on-site personnel and dangerous areas, greatly improving the safety of blasting operations. In addition, through data encryption and multiple identity authentication mechanisms, it ensures that only authorized personnel can perform detonation operations, further improving the operational safety of the system.

[0056] 5. Reduce signal interference Wireless communication technology avoids the problems of misoperation and signal loss caused by electromagnetic interference or signal attenuation in wired systems. Wireless detonators improve anti-interference capabilities through multi-channel concurrency and adaptive frequency band switching, ensuring the stability and reliability of communication in complex environments.

[0057] 6. Flexibility and scalability The wireless blasting system can be flexibly expanded according to the scale of the project, from a single blasting point to multi-point collaborative operations, and can adapt to blasting tasks of different scales and complexities through the collaboration of multiple host and slave machines.

[0058] In one embodiment, a micro control unit is provided, which may be a server, and its internal structure diagram may be as follows: Figure 4 As shown. The micro control unit includes a processor, a memory, a network interface and a database connected through a system bus. Among them, the processor of the micro control unit is used to provide computing and control capabilities. The memory of the micro control unit includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a program and a database. The internal memory provides an environment for the operation of the operating system and the program in the non-volatile storage medium. The database of the micro control unit is used to store periodic task allocation data, such as configuration files, theoretical operating parameters and theoretical deviation value ranges, task attribute information, etc. The network interface of the micro control unit is used to communicate with an external terminal through a network connection. When the program is executed by the processor, a detonator registration and backup system is implemented.

The specific microcontroller unit may include more or fewer components than those shown in the figure, or combine certain components, or have a different arrangement of components.

[0060] In one embodiment, a computer device is provided, including a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, the following steps are implemented: The wireless host is arranged in a safe area outside the blasting area to control the operation of the wireless slaves through wireless signals, and the wireless slaves are distributed at various blasting points that need to be controlled in the blasting area.

After the digital electronic detonator is fully charged, it can meet the conditions for detonation. When the wireless host sends a detonation command, the detonation instruction is transmitted to each wireless slave through a wireless signal. After receiving the instruction, the wireless slave immediately sends a detonation signal to the load network, thereby controlling all load digital electronic detonators to complete the detonation according to the delay setting.

[0061] In one embodiment, when the processor executes the computer program, the wireless host monitors the status of the wireless slave through the sampling and measuring circuit, including: whether the signal transmission is successful or not, the detonation status of the digital electronic detonator, to ensure that each link is executed accurately.
