Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] The following description, with reference to the accompanying drawings, describes an intelligent safety belt with automatic alarm function and its application method, according to embodiments of this application.

[0024] Figure 1 This is a schematic diagram of the structure of a multi-channel charging device for a wireless electronic detonator proposed in an embodiment of this application, as shown below. Figure 1 As shown, the device includes: a housing 10 and a charging compartment matrix 20.

[0025] The housing 10 is used to carry and protect the charging compartment matrix 20.

[0026] The charging case matrix 20 includes multiple charging cases 21, each of which is equipped with a corresponding quick-connect port 22 at its bottom.

[0027] In cases where it is necessary to charge at least one wireless electronic detonator, quick-connect port 22 is connected to the quick-connect plug of the wireless receiver of the wireless electronic detonator.

[0028] The charging compartment 21 is used to charge the wireless receiver of the wireless electronic detonator after the housing 10 is powered on, based on the charging circuit formed by the quick-connect port 22 and the quick-connect plug.

[0029] Specifically, the housing 10 in this application is used to carry the charging chamber matrix 20 and support the charging chamber matrix 20 for charging. The housing 10 can be connected to an external power supply device to charge the wireless electronic detonator using an external power source. The dimensions and materials of the housing 10 can be determined based on actual factors such as the charging chamber matrix 20 it is mounted on.

[0030] For example, the dimensions of the housing 10 can be set as: length × width × height = 550 × 400 × 600 mm, and the outer shell meets the explosion-proof standard to provide explosion-proof protection for the charging compartment matrix 20 inside.

[0031] The charging compartment matrix 20 consists of multiple charging compartments 21. Each charging compartment 21 can charge a wireless electronic detonator individually based on the quick-connect port 22 at its bottom, thereby enabling simultaneous charging of multiple wireless electronic detonators.

[0032] For example, such as Figure 2 As shown, the charging chamber matrix can be composed of 5×4 charging chambers 21 arranged in a grid, and the spacing between each charging chamber 21 meets the heat diffusion requirements when charging the wireless electronic detonator. Figure 2 The device shown can charge 20 wireless electronic detonators simultaneously. like Figure 3 As shown, each charging compartment 21 is equipped with a corresponding quick-connect port 22 at the bottom. This quick-connect port can establish an electrical connection with the quick-connect plug of the wireless receiver of the wireless electronic detonator, enabling plug-and-play functionality.

[0033] Since the power supply for the wireless electronic detonator is a wireless receiving device, charging the wireless electronic detonator in this application is equivalent to charging the wireless receiving device within the detonator. The wireless receiving device described in this application includes a quick-connect plug; for example, for a cylindrical wireless receiving device measuring 48×3.5cm, a quick-connect plug is located on one end face. When it is necessary to charge a wireless electronic detonator, the quick-connect plug of the wireless receiving device is connected to a quick-connect port in a charging compartment. After the housing 10 is powered on, based on the conductive circuit formed by the quick-connect port and the quick-connect plug, the charging compartment can charge the battery in the wireless receiving device according to control commands.

[0034] In one embodiment of this application, the charging case matrix further includes: a plurality of charging buttons, the plurality of charging buttons being arranged on the upper surface of the charging case matrix, each charging case corresponding to one charging button; the charging buttons are used to control the corresponding charging case to charge the connected wireless receiving device.

[0035] Specifically, such as Figure 2 As shown, each charging compartment 21 corresponds to a charging button 23. The charging button 23 is arranged on the plane at the top of the charging compartment 21. When the charging button 23 is in the pressed state, the charging circuit is connected and a charging command is sent to the charging compartment 21, so that the corresponding charging compartment 21 charges the connected wireless receiving device.

[0036] In one embodiment of this application, the charging case matrix further includes: a plurality of charging indicator lights, which are arranged on the upper surface of the charging case matrix, with each charging case corresponding to one charging indicator light; the charging indicator lights are used to display the charging status of the wireless receiving device currently being charged.

[0037] Specifically, such as Figure 2As shown, each charging compartment 21 also corresponds to a charging indicator light 24. The charging indicator light 24 is arranged on the same end face as the charging button 23. The charging indicator light 24 indicates the charging status of the wireless receiving device being charged by displaying different colors, including charging in progress and charging complete.

[0038] In one embodiment of this application, each quick-connect socket includes a gold-plated elastic contact and a silicone sealing ring. Specifically, this embodiment protects the quick-connect socket 22 by configuring each quick-connect socket 22 with a gold-plated elastic contact and a silicone sealing ring. The gold-plated elastic contact enhances the conductivity and corrosion resistance of the quick-connect socket 22, while the silicone sealing ring provides waterproofing, achieving the required waterproof rating for charging.

[0039] In one embodiment of this application, the multi-channel charging device further includes a communication module, which is used to connect to an external control device using wired or wireless communication methods to receive control commands sent by the control device.

[0040] Specifically, in this embodiment, the multi-channel charging device can interact with external control equipment via wired or wireless connection, receiving commands from the external control equipment to configure the wireless receiving device. This enables not only charging of the wireless receiving device for wireless electronic detonators but also configuration of the wireless receiving device for detonation control.

[0041] For example, the external control device can be a user's handheld tablet computer. Based on the data sent by the handheld tablet computer, the multi-channel charging device can perform operations such as synchronization, networking, and delay time settings for the connected wireless electronic detonators. That is, the multi-channel charging device of this application also has multiple application functions such as synchronization, networking, and delay time settings for wireless electronic detonators.

[0042] In summary, the multi-channel charging device for wireless electronic detonators according to this application embodiment is equipped with a quick-connect port at the bottom of the charging compartment. When charging a wireless electronic detonator is required, the quick-connect port is connected to the quick-connect plug of the wireless receiver of the wireless electronic detonator, enabling plug-and-charge functionality. After charging is complete, the quick-connect plug of the wireless receiver is unplugged for subsequent detonation. Furthermore, the charging compartment matrix of this device can support simultaneous electrical connections with multiple wireless receivers, allowing for synchronous charging of multiple wireless electronic detonators. Therefore, this multi-channel charging device can charge multiple wireless electronic detonators simultaneously, meeting the charging needs of wireless electronic detonators in practical applications and facilitating their normal application. It improves the convenience and efficiency of charging wireless electronic detonators.

[0043] To more clearly illustrate the specific implementation process of the multi-channel charging device for wireless electronic detonators in this application for charging and applying wireless electronic detonators, the following detailed description is based on an application method of the multi-channel charging device for wireless electronic detonators proposed in an embodiment of this application. This method is applied to the multi-channel charging device for wireless electronic detonators in the above embodiments, that is, the actual application of the multi-channel charging device in the above embodiments. The various devices involved in this method are as described in the above embodiments and will not be repeated here.

[0044] Figure 4 A flowchart illustrating an application method for a multi-channel charging device for a wireless electronic detonator, as proposed in this application embodiment, is shown below. Figure 4 As shown, the method includes the following steps: Step S101: In response to the need to charge at least one wireless electronic detonator, power is supplied to the housing.

[0045] Specifically, when it is necessary to charge one or more wireless electronic detonators, power is supplied to the enclosure. For example, the power plug on the enclosure is connected to a socket to power the enclosure, which then facilitates the subsequent supply of power to the wireless electronic detonators through the charging compartment.

[0046] Step S102: Connect the quick-connect plug of the wireless receiver of the wireless electronic detonator to the quick-connect port of any charging compartment.

[0047] Specifically, align the wireless receiver of the wireless electronic detonator with the quick-connect port in the charging compartment and insert it into the box. The specific charging compartment can be determined according to the actual situation. For example, when there are multiple wireless electronic detonators to be charged, the wireless receivers can be inserted into the quick-connect ports in the box in sequence according to the arrangement of the charging compartments.

[0048] Step S103: Press the charging button corresponding to the charging case to charge the wireless receiver, and determine the charging status of the wireless receiver according to the charging indicator light corresponding to the charging case.

[0049] Specifically, for the charging case with the wireless receiver connected, press the corresponding charging button next to it to start charging the wireless receiver. During the charging process, you can determine the charging status of the wireless receiver by the color of the charging indicator light on the charging case. For example, if the charging indicator light is red, it means that the wireless receiver is charging, and if the charging indicator light is green, it means that the wireless receiver has finished charging.

[0050] Step S104: In response to the completion of charging of the wireless receiving device, control the multi-channel charging device to establish a communication connection with the control device, and set the synchronization time and delay time of the wireless receiving device through the multi-channel charging device according to the received control command.

[0051] Specifically, after the wireless receiving device has finished charging, the multi-channel charging device can be used to configure the pre-detonation control of the wireless receiving device for the wireless electronic detonator. First, a communication connection is established between the multi-channel charging device and the control equipment; for example, a wired or wireless connection is established between the user's handheld tablet and the multi-channel charging device. Then, control commands and application data can be sent to the multi-channel charging device via the handheld tablet, and the multi-channel charging device will then synchronize the wireless receiving device and set the delay time based on the received commands.

[0052] In one embodiment of this application, the wireless receiving device is synchronized via a multi-channel charging device, including: receiving a reference time sent by a control device based on a communication connection, and synchronizing the clock signals of the wireless receiving devices of each wireless electronic detonator according to the reference time; receiving a detection signal sent by the control device, and detecting the timer value of each wireless receiving device in combination with the reference time and the detection signal.

[0053] Specifically, this embodiment uses time synchronization to ensure the accuracy of the delay time set for each wireless receiving device in practical applications. Time synchronization can be performed by first calibrating a calibration signal. The control device sends a calibration signal to the wireless receiving device, which is used to calibrate the clock of the wireless receiving device, ensuring the accuracy of the clock signal.

[0054] Then, reference time synchronization is performed. The multi-channel charging device writes the reference time sent by the control device to each wireless receiver to synchronize the clocks of all wireless electronic detonators and trigger the timers of the control device and the wireless receivers to start timing.

[0055] Finally, the timer value is checked. The multi-channel charging device transmits a wireless detection signal from the control device to the electronic detonator to detect the timer value of the electronic detonator. The timer value is the time difference between the reference time and the detection time. Once it is confirmed that the timer value of each wireless electronic detonator is consistent with the timing of the control device, a detonation control command is sent to control the wireless electronic detonator to detonate after a preset time.

[0056] In one embodiment of this application, setting a delay time for a wireless receiving device via a multi-channel charging device includes: receiving the delay time of each wireless receiving device sent by a communication connection control device, and transmitting the delay time to the corresponding wireless receiving device.

[0057] Specifically, this embodiment sets different delayed detonation times for each wireless receiving device. As an example, the control device can automatically read the ID code of each wireless electronic detonator. Based on the position of each wireless electronic detonator in the detonation circuit as required in the blasting design scheme and the ID code of each wireless electronic detonator, the required delay time for each wireless electronic detonator is determined, and the corresponding delay time is written to the wireless receiving device of each wireless electronic detonator through a multi-channel charging device.

[0058] As another example, users can also create a delay list in the delay time setting interface of the human-machine interface of the control device, set the delay time corresponding to each wireless electronic detonator, and then write the delay time to each wireless receiver through the multi-channel charging device.

[0059] In one embodiment of this application, after the wireless receiving device is synchronized and the delay time is set by the multi-channel charging device, the method further includes: connecting the wireless receiving device to the socket of the corresponding basic detonator, and placing the connected wireless electronic detonator in the borehole.

[0060] Specifically, in this embodiment, the wireless receiver of the wireless electronic detonator that has been fully charged and whose application data has been set is removed from the charging device and connected to the corresponding base detonator. For example, the quick plug of the wireless receiver is connected to the base detonator with a quick plug, and then it is placed into the corresponding blast hole for blasting operations.

[0061] In summary, the application method of the multi-channel charging device for wireless electronic detonators according to the embodiments of this application allows for plug-and-charge functionality when charging a wireless electronic detonator. This enables simultaneous charging of multiple wireless electronic detonators, meeting the charging needs of wireless electronic detonators in practical applications. Furthermore, this method allows for synchronization and delay time settings for the wireless receiving device, enriching the functions of the multi-channel charging device and improving the application efficiency of wireless electronic detonators.
