[0002] Electronic detonators, also known as digital electronic detonators or industrial digital electronic detonators, are detonators that use electronic control modules to control the detonation process. Wired connections are commonly used in electronic detonator applications, resulting in significant losses in the busbars connecting the detonators. Therefore, the industry is currently seeking to replace conventional wired electronic detonator detonation with wireless communication technology, which can reduce the use of busbars to some extent and increase blasting safety.

[0067] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0068] Example 1:

[0069] like Figure 1 , Figure 2 , Figure 3As shown, an electronic detonator initiation system based on wireless radio frequency communication includes a wireless transceiver controller and a wireless terminal device.

[0070] The wireless transceiver controller includes:

[0071] The wireless transceiver controller controls the detonation process of the system, issues control commands, and transmits and receives wireless signals.

[0072] In this embodiment, the wireless transceiver controller includes:

[0073] The control platform controls the detonation process and issues control commands.

[0074] The wireless communication platform communicates with the control platform and wireless terminal devices, sending control commands from the control platform to the wireless terminal devices and receiving information from the wireless terminal devices and sending it back to the control platform.

[0075] The control platform can be a handheld platform, such as those running Android or Apple systems, or a fixed platform, such as a desktop computer. An electronic detonator detonation app is pre-installed on the control platform to set and control the overall system detonation process; that is, the detonation of the electronic detonators is controlled by the control platform, and all commands are initiated by the control platform.

[0076] In this embodiment, the wireless communication platform includes a data parsing unit and a wireless transceiver module;

[0077] The data parsing unit receives instructions from the control platform, processes them, and then communicates with the wireless terminal device through the wireless transceiver module; the data parsing unit receives data transmitted by the wireless transceiver module, processes it, and then sends it to the control platform.

[0078] The wireless transceiver module communicates wirelessly with the wireless terminal device and interacts with the data parsing and processing unit.

[0079] The data parsing unit connects to the control platform via a serial port, and the control platform sends commands to the data parsing unit via the serial port. The data parsing unit and the wireless transceiver module can be packaged as a single unit, or the control platform, data parsing unit, and wireless transceiver module can be packaged as a single unit, such as a mobile phone (with data processing and wireless communication capabilities).

[0080] The wireless terminal device is communicatively connected to the electronic detonator and reads the current data information of the electronic detonator connected to it. The wireless terminal device is also wirelessly connected to the wireless transceiver controller and receives control commands from the controller. It performs registration, networking, password verification, delayed writing, charging, and detonation of all electronic detonators connected to it, and reads the current data information of the electronic detonators connected to it. Figure 4 As shown,

[0081] The wireless transceiver controller reads the voltage and current of the wireless terminal device in real time, as well as the current data information of the electronic detonator communicating with the wireless terminal device. The current data information of the electronic detonator includes information such as registration, networking, password verification, delay writing, charging, and detonation. The wireless transceiver controller reads the electronic detonator data information from the wireless terminal device in a question-and-answer manner.

[0082] In this embodiment, the wireless terminal device includes:

[0083] The wireless communication unit is wirelessly connected to the wireless transceiver controller, receives instructions from the wireless transceiver controller, and sends data to the transmitting wireless transceiver controller.

[0084] The data processing unit interacts with the wireless communication unit to process the data received and transmitted by the wireless communication unit; and controls the bus drive unit to detonate each electronic detonator through SPI communication with the wireless communication unit.

[0085] The bus driver unit interacts with the data processing unit and the electronic detonator; it receives control commands from the wireless transceiver controller, registers, networks, verifies passwords, performs delayed writing, charges, and detonates all electronic detonators connected to it, and reads the current data information of the electronic detonators connected to it; the bus driver unit contains an H-bridge circuit, and the data processing unit controls the H-bridge to output corresponding commands to the bus to achieve communication with the electronic detonators.

[0086] The power supply unit provides power to the wireless communication unit, data processing unit, and bus drive unit.

[0087] In this example, the wireless communication unit uses a ready-made wireless communication module with a wireless communication frequency of 430-434.79MHz; the wireless communication unit uses the SPI bus to interact with the data processing unit.

[0088] The data processing unit sends commands to detonate the electronic detonator via the control bus.

[0089] In this example, the power supply unit includes a battery and a power management module. The power management module detects the battery level and controls the output voltage to be stable. Specifically, a low-cost DC-DC power chip is used to step down the 9-12V voltage to a stable 5V voltage to power the subsequent stages.

[0090] In this embodiment, as Figure 5 As shown, the wireless transceiver controller, the wireless terminal device, and the electronic detonator exchange information using or only using encrypted communication protocols;

[0091] The wireless transceiver controller, the wireless terminal device, and the electronic detonator send encrypted information according to the frame format of the encrypted communication protocol; the frame format of the encrypted communication protocol consists of frame header, frame length, data bits, check bits, and frame trailer from beginning to end.

[0092] The wireless transceiver controller, the wireless terminal device, the electronic detonator, and the wireless relay device decrypt information in the following manner:

[0093] Step 1: Identify whether the received information is an encrypted communication protocol by checking the frame header and frame trailer information; if not, discard the information; if so, proceed to Step 2.

[0094] Step 2: Determine if the frame length matches the data length of the encrypted communication protocol; if they do not match, send a message indicating a data error to the device that sent the information; if they match, proceed to Step 3.

[0095] Step 3: Perform a private CRC check on the received information and compare the check result with the check bit information of the encrypted communication protocol; if they do not match, send a message indicating that the information data is incorrect to the device that sent the information; if they match, proceed to step 4.

[0096] Step 4: Extract the data information from the data bits of the received information.

[0097] In this embodiment, as Figure 6 As shown, the wireless transceiver controller performs the following steps for all electronic detonators connected to the wireless terminal device: registration, networking, password verification, delay writing, charging, and detonation:

[0098] Step 1: The wireless transceiver controller controls the wireless terminal device via LoRa wireless communication and reads the three-code information of the electronic detonator communicating with the wireless terminal.

[0099] Step 2: The wireless terminal device transmits the collected three-code information of the electronic detonator to the wireless transceiver controller via LoRa wireless communication.

[0100] Step 3: The wireless transceiver controller registers and inputs information about the electronic detonators;

[0101] Step 4: The wireless transceiver controller controls the wireless terminal equipment to complete the networking and testing of electronic detonators;

[0102] Step 5: The wireless transceiver controller controls the wireless terminal device to complete the password verification and delayed writing of the electronic detonator.

[0103] Step 6: The wireless transceiver controller controls the wireless terminal device to complete the charging of the electronic detonator;

[0104] Step 7: The wireless transceiver controller controls the wireless terminal device to detonate the electronic detonator.

[0105] Current conventional electronic detonator registration methods include QR code registration and manual data entry registration. QR code registration has drawbacks: it becomes inconvenient to register detonators when the wire clip code is lost or the QR code is printed unclearly. Manual data entry registration has drawbacks: it's suitable for situations where the shell numbers fall within a continuous range or when the number of detonators is small. However, when the shell numbers are not within a continuous range and the number of detonators is large, manual data entry becomes a tedious, boring, and time-consuming operation.

[0106] Using the self-developed method described above, a single wireless transceiver controller can connect to multiple wireless terminal devices, enabling the simultaneous search for electronic detonators on multiple devices. The electronic detonator data is automatically read by the wireless terminal devices and reported back to the wireless transceiver controller, significantly reducing the data entry time and error rate. This achieves automated and rapid registration and networking of electronic detonators, thereby improving efficiency.

[0107] In the above steps, all control commands for the electronic detonators are uniformly issued by the wireless transceiver controller, and the entire process is managed by the wireless transceiver controller. The wireless transceiver controller sends the command protocol to the wireless terminal device wirelessly. Upon receiving a command protocol, the wireless terminal device parses the command and controls the information carried in the bus communication of the control terminal device according to different commands. The electronic detonator feeds back its own information to the wireless terminal device through the bus it is connected to (the bus of the wireless terminal device). The wireless terminal device then sends the electronic detonator information wirelessly to the wireless transceiver controller, which determines the current status of the electronic detonator. By transmitting and receiving information about the entire detonation process through the wireless transceiver controller, the purpose of wireless detonation of the detonators is achieved.

[0108] In this embodiment, when the wireless transceiver controller communicates with the wireless terminal device, the following steps are included:

[0109] Step 1: The wireless transceiver controller sends a response command to the wireless terminal device and starts timing;

[0110] Step 2: If the wireless transceiver controller does not receive a response from the wireless terminal device within the predetermined time, repeat step 1, record the number of retries, and proceed to step 3.

[0111] Step 3: Determine whether the number of retries has reached the preset value. If not, proceed to step 1; if so, the wireless transceiver controller determines that the wireless terminal communication has timed out.

[0112] By incorporating or integrating the above methods into the communication process, abnormalities in wireless terminal devices can be monitored and reported, enabling rapid troubleshooting.

[0113] In this embodiment, the technical solution uses a mobile phone as a control carrier to directly control the detonator search network and detonation. In this mode, the handheld device communicates directly with the wireless terminal equipment at a distance of 300-500 meters.

[0114] Example 2:

[0115] like Figure 7 , Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that it also includes at least two wireless relay devices to wirelessly relay the wireless communication between the wireless transceiver controller and the wireless terminal device. The main function of the wireless relay devices is to split, assemble, and forward the command data of the wireless transceiver controller, that is, to act as a data relay, effectively improving the control distance of the system over the electronic detonator.

[0116] Specifically, in Example 1, without the use of a wireless relay device, the communication distance between the wireless transceiver controller and the wireless terminal device is 300-500 meters. However, in this example, with the addition of a wireless relay device, the communication distance between the wireless transceiver controller and the wireless terminal device can reach 1000-2000 meters.

[0117] Specifically, the wireless relay device includes:

[0118] A wireless communication system that transmits and receives data between a wireless transceiver controller and wireless terminal devices; it acts as a communication bridge between the wireless transceiver controller and the relay, and between the relay and the terminal, to realize data communication transmission.

[0119] The data processing system processes the data transmitted and received by the wireless communication system and controls the data interaction between the wireless transceiver controller and the wireless terminal equipment.

[0120] Radio frequency power amplifier systems enhance the transmission and reception power of wireless communication systems, thereby increasing communication distance;

[0121] The power supply system provides power to the wireless communication system, data processing system, and RF power amplifier system; controls battery charging; detects battery level; and controls the voltage supplied to the wireless communication system, data processing system, and RF power amplifier system. Specifically, the power supply system uses 5V / 2A charging with a Type-C interface, and the battery system's power supply range is DC9V to DC12V.

[0122] The bus system provides an interactive data interface between the data processing system, the wireless communication system, and the RF power amplifier system.

[0123] In this embodiment, the wireless communication system includes at least two wireless communication modules, each receiving and transmitting data from a wireless terminal device in one channel. Simultaneously, the wireless communication system employs multi-antenna mode communication in its structure to process data from terminals in multiple channels.

[0124] In this embodiment, the communication between the wireless relay device and the wireless transceiver controller and the wireless terminal device adopts the encrypted communication protocol in Embodiment 1.

[0125] In this embodiment, as Figure 9 As shown, the wireless transceiver controller registers, networks, verifies passwords, performs delay writing, charges, and detonates all electronic detonators that are connected to the wireless terminal device through a wireless relay device.

[0126] The communication protocol between the wireless transceiver controller and the wireless relay device is different from the communication protocol and method between the wireless relay device and the wireless terminal device.

[0127] Specifically, the wireless transceiver controller sends commands to the wireless relay device. The wireless relay device parses the protocol data, assembles it into a data protocol suitable for the wireless terminal device, and forwards it to the wireless terminal device. The wireless terminal device receives the corresponding commands and executes the corresponding control logic. Similarly, the reverse process is used for reverse information transmission. In terms of communication methods, for long-distance communication, the wireless relay device and the wireless terminal device communicate via a wireless terminal serial number (SN).

[0128] Different communication protocols and methods can effectively prevent data interference and improve the overall communication stability of long-distance network detonation.

[0129] When the wireless transceiver controller communicates with the wireless terminal device through the wireless relay device, it includes the following steps:

[0130] The wireless transceiver controller sends a command to the wireless relay device requiring a response from the wireless terminal device and starts timing; if the wireless transceiver controller does not receive a response from the wireless relay device within the predetermined time, it determines that the wireless relay device has timed out.

[0131] The wireless relay device sends the instruction from the wireless transceiver controller requiring a response from the wireless terminal device to the wireless terminal device and starts timing; if the wireless relay device does not receive a response from the wireless terminal device within the predetermined time, it retryes the above-mentioned sending process, in which the wireless relay device sends the instruction requiring a response to the wireless terminal device; when the number of retries reaches a preset value, the wireless relay device sends a communication timeout message to the wireless transceiver controller.

[0132] Specifically: The wireless transceiver controller uses the same protocol in communication with the wireless repeater and the wireless terminal device; the only difference between them is the frame header. The wireless transceiver controller distinguishes between a response from the wireless repeater and a response from the wireless terminal device by identifying the frame header. When a wireless repeater is present, the wireless transceiver controller sends a relay frame header instruction to the wireless repeater.

[0133] The wireless relay device responds to the wireless transceiver controller and, after parsing the instructions, sends the terminal frame header instruction to the wireless terminal device.

[0134] If the wireless terminal device responds, the wireless relay device sends the relay frame header information to the wireless transceiver controller.

[0135] If the wireless terminal device does not respond after a timeout, the wireless relay device retransmits the command. If it still does not receive a response from the wireless terminal device after multiple retransmissions, the wireless relay device sends information containing a relay frame header to the wireless transceiver controller. The wireless transceiver controller determines that the wireless terminal device has not responded based on the relay frame header information it has identified, and at this point, it can be determined that the wireless terminal device has timed out.

[0136] If the wireless repeater does not respond, the wireless transceiver controller retransmits the command. If it fails to receive a response from the wireless repeater multiple times, the wireless repeater is deemed to have timed out.

[0137] By incorporating or integrating the above methods into the communication process, abnormalities in wireless terminal devices and wireless relay devices can be monitored and reported, enabling rapid troubleshooting.

[0138] This embodiment, by adding a wireless relay device, enables a maximum blasting distance of 2000 meters and a maximum detonation capacity of 4000 detonators. Specifically, when this scheme is applied to long-distance, large-scale blasting operations, it uses a communication mode of wireless transceiver controller – wireless relay device – wireless terminal device. In this mode, the wireless relay device manages all electronic detonators centrally. All electronic detonator information is packaged and sent to the wireless transceiver controller. After processing the data, the wireless transceiver controller sends instructions to the wireless relay device, which then distributes the information to its respective wireless terminal devices. In this mode, the wireless transceiver controller does not communicate directly with the wireless terminal devices.

[0139] Example 3:

[0140] like Figure 10 As shown, the only difference between this embodiment and embodiment 1 is that the wireless terminal device in this embodiment adopts the same design scheme as the wireless relay device in embodiment 1, that is, the wireless relay device in embodiment 1 is used as the detonation terminal device.

[0141] Specifically, the wireless terminal device in this embodiment includes:

[0142] The wireless terminal device includes:

[0143] The wireless communication system is wirelessly connected to the wireless transceiver controller, receives instructions from the wireless transceiver controller, and sends data to the transmitting wireless transceiver controller.

[0144] The data processing system interacts with the wireless communication system, processing the data received and transmitted by the wireless communication system.

[0145] Radio frequency power amplifier systems enhance the transmit and receive power of wireless communication systems;

[0146] The power supply system provides power to the wireless communication system, data processing system, and RF power amplifier system; controls battery charging; detects battery power; and controls the voltage supplied to the wireless communication system, data processing system, and RF power amplifier system.

[0147] The bus system provides an interactive data interface between the data processing system, wireless communication system, power supply system, RF power amplifier system, and electronic detonators. It receives control commands from the wireless transceiver controller, registers, networks, verifies passwords, performs delayed writing, charges, and detonates all electronic detonators connected to it, and reads the current data information of the electronic detonators connected to it.

[0148] The bus system contains an H-bridge circuit. The data processing unit controls the H-bridge to output corresponding instructions to the bus in order to achieve communication with the electronic detonator.

[0149] In this embodiment, the electronic detonator initiation system based on wireless radio frequency communication is suitable for small-scale applications. It does not use any wireless relay equipment and directly connects all the electronic detonators to be detonated to the wireless terminal equipment through the bus output interface.

[0150] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
