[0048] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0049] Example 1:

[0050] like Figure 1 , Figure 2 As shown, an electronic detonator initiation system based on wireless radio frequency communication includes:

[0051] The wireless transceiver controller controls the detonation process of the system, issues control commands, and receives wireless signals.

[0052] The wireless terminal device communicates with the electronic detonator and reads the current data information of the electronic detonator connected to it. The wireless terminal device also communicates with the wireless transceiver controller and receives control commands from the wireless transceiver controller. It performs registration, networking, password verification, delay writing, charging, and detonation on all electronic detonators connected to it and reads the current data information of the electronic detonators connected to it.

[0053] In this embodiment, the wireless transceiver controller includes:

[0054] The control platform controls the detonation process and issues control commands.

[0055] 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.

[0056] 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.

[0057] In this embodiment, the wireless communication platform includes a data parsing unit and a wireless transceiver module;

[0058] 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.

[0059] The wireless transceiver module communicates wirelessly with the wireless terminal device and interacts with the data parsing and processing unit.

[0060] 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).

[0061] In this embodiment, the wireless terminal device includes:

[0062] 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.

[0063] 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.

[0064] 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.

[0065] The power supply unit provides power to the wireless communication unit, data processing unit, and bus drive unit.

[0066] 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.

[0067] The data processing unit sends commands to detonate the electronic detonator via the control bus.

[0068] 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.

[0069] 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.

[0070] Example 2:

[0071] like Figure 3 , Figure 4 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.

[0072] Specifically, in Example 1, without the use of a wireless repeater, the communication distance between the wireless transceiver controller and the wireless terminal device was 300-500 meters. However, in this example, with the addition of a wireless repeater, the communication distance between the wireless transceiver controller and the wireless terminal device can reach 1000-2000 meters. Specifically, the wireless repeater includes:

[0073] 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.

[0074] 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.

[0075] Radio frequency power amplifier systems enhance the transmission and reception power of wireless communication systems, thereby increasing communication distance;

[0076] 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.

[0077] The bus system provides an interactive data interface between the data processing system, the wireless communication system, and the RF power amplifier system.

[0078] 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.

[0079] 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.

[0080] Example 3:

[0081] like Figure 5 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.

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

[0083] 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.

[0084] The data processing system interacts with the wireless communication system, processing the data received and transmitted by the wireless communication system.

[0085] Radio frequency power amplifier systems enhance the transmit and receive power of wireless communication systems;

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model 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 solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
