Description

Technical Field

[0001] The present invention relates to the technical field of through - the - earth communication, and particularly to a portable wireless through - the - earth communication device. Background Art

[0002] In many current fields, such as mining, underground engineering construction, geological exploration, and emergency rescue scenarios, reliable underground communication technology is crucial. However, traditional communication methods expose many insurmountable defects when facing complex underground environments.

[0003] As one of the more common methods, wired communication requires laying a large number of cables. In complex underground terrains, the laying of cables faces huge challenges. Not only is the construction difficult and costly, but it is also extremely vulnerable to damage caused by factors such as underground rock movement and geological changes. Once a fault occurs, troubleshooting and repair work are time - consuming and laborious, seriously affecting the stability and continuity of communication.

[0004] Based on this, there is an urgent need for a portable wireless through - the - earth communication device that can achieve the convenience and efficiency of communication during underground operations. Summary of the Invention

[0005] One of the objectives of the present invention is to provide a portable wireless through - the - earth communication device that can achieve the convenience and efficiency of communication during underground operations.

[0006] To achieve the above objective, a portable wireless through - the - earth communication device is provided, which includes a portable operation device and a low - frequency communication device;

[0007] The portable operation device includes a first controller, a first communication module, and a display module. The first controller is electrically connected to the first communication module and the display module respectively;

[0008] The low - frequency communication device includes a second controller, a second communication module, a controllable low - frequency signal source, a power amplifier, a high - voltage capacitor resonator, and a circular transmitting antenna. The second controller is electrically connected to the second communication module and the controllable low - frequency signal source respectively. The output end of the controllable low - frequency signal source is connected to the input end of the power amplifier. The output end of the power amplifier is connected to the input end of the high - voltage capacitor resonator. The output end of the high - voltage capacitor resonator is connected to the circular transmitting antenna;

[0009] The portable operation device and the low - frequency communication device are communicatively connected through the first communication module and the second communication module.

[0010] Technical principle and effect of this solution: In this solution, the first controller in the portable operation device is responsible for generating control instructions or information to be transmitted, and this information is sent out in the form of wireless signals through the first communication module. After the second communication module of the low-frequency communication device receives this signal, it passes it to the second controller. The second controller controls the power amplifier, high-voltage capacitor resonator, and circular transmitting antenna to work according to the received signal. Specifically, the function of the power amplifier is to amplify the input electrical signal and enhance the signal intensity. The high-voltage capacitor resonator modulates the amplified signal, and through resonance, makes the signal meet the specific frequency and phase requirements suitable for ground-penetrating transmission. Finally, the circular transmitting antenna emits the modulated low-frequency signal underground. These low-frequency signals will be received by the receiving end set underground, thereby realizing the control of the devices at the receiving end, such as the detonation of electronic detonators.

[0011] In this solution, the device is divided into a portable operation device and a low-frequency communication device, which is convenient for the operator to carry to different locations for operation. The operator can hold the portable operation device and flexibly control the low-frequency communication device, getting rid of the shackles of traditional wired communication and being applicable to various complex terrains and mobile operation scenarios. That is, it realizes the convenience and efficiency of communication during underground operations.

[0012] Through the coordinated work of the power amplifier, high-voltage capacitor resonator, and circular transmitting antenna in the low-frequency communication device, low-frequency signals suitable for penetrating media such as soil can be generated. When low-frequency signals propagate underground, they have lower attenuation characteristics compared to high-frequency signals, thereby realizing long-distance ground-penetrating communication and meeting the communication requirements in fields such as mine communication and underground detection.

[0013] The display module in the portable operation device can intuitively display content such as the communication status and received information, facilitating the operator to understand the communication situation in real time. At the same time, the operator can conveniently and quickly send control instructions to the low-frequency communication device through the first controller, realizing efficient information interaction.

[0014] Furthermore, the low-frequency communication device further includes a control integration box, and the second controller, second communication module, power amplifier, high-voltage capacitor resonator, and circular transmitting antenna are all arranged in the control integration box.

[0015] Beneficial effects: The control integration box centrally protects key components such as the second controller, the second communication module, the power amplifier, the high-voltage capacitor resonator, and the circular transmitting antenna. Its box body made of metal or high-strength engineering plastics with a certain strength and protection performance can effectively resist external physical damages such as collisions and squeezes, reduce the risk of equipment damage caused by accidents, and greatly improve the reliability and stability of the low-frequency communication device. The control integration box provides a regular installation space for the internal components. Inside the box, a reasonable layout design can be carried out according to the functions and connection requirements of each component. For example, the power amplifier and the high-voltage capacitor resonator, which are closely related to each other, are arranged adjacent to each other, shortening the circuit connection length between them, reducing the loss during signal transmission, and improving the signal processing efficiency of the entire low-frequency communication device.

[0016] Further, the control integration box includes a main box body and a movable drawer arranged inside the main box body. Slide rails are arranged on the inner side wall of the lower end surface of the main box body, and pulleys are arranged on the outer side wall of the lower end surface of the movable drawer. The movable drawer moves inside the main box body through the sliding cooperation of the pulleys and the slide rails.

[0017] Beneficial effects: Through the cooperation of the pulleys and the slide rails, the movable drawer can easily slide in and out of the main box body. When it is necessary to operate, maintain, or replace the components in the drawer, there is no need to operate difficultly inside the narrow box body in the traditional way. Just pull out the drawer, and the operation can be carried out at a more open and convenient position, greatly improving the work efficiency. In the non-operation state, the movable drawer is located inside the main box body, jointly forming a multi-layer protection for the internal components with the main box body. The cooperation of the pulleys and the slide rails can buffer external vibrations and impacts to a certain extent, reducing the influence on the components in the drawer. Moreover, when the main box body has good protection performance, the components in the movable drawer can also be better protected, reducing the risk of damage caused by external factors.

[0018] Further, the control integration box includes a main box and a box door. A plurality of push-pull drawers are sequentially arranged in the main box from top to bottom. The second controller, the second communication module, the power amplifier, the high-voltage capacitor resonator, and the circular transmitting antenna are sequentially arranged in each push-pull drawer.

[0019] Beneficial effects: By placing different components in different push-pull drawers respectively, when a certain component fails and needs to be maintained, it can be accurately located in the corresponding drawer. The user only needs to pull out the corresponding drawer to quickly access the target component, greatly shortening the fault troubleshooting and repair time. For example, if there is a problem with the power amplifier, the drawer containing it can be directly opened for maintenance, without having to search among numerous components, improving the work efficiency.

[0020] Placing a single or a small number of related components in each drawer helps in targeted design according to the heat dissipation requirements of the components. Independent heat dissipation channels or devices can be set on each drawer to ensure that each component operates at an appropriate temperature. At the same time, arranging the drawers in sequence from top to bottom makes the internal structure of the entire control integration box more regular and orderly, facilitating the connection and management of cables and reducing signal interference.

[0021] Each drawer is equivalent to an independent protection unit, which plays an isolation and protection role for the internal components to a certain extent. When an abnormality (such as short circuit and fire) occurs in the components of a certain drawer, the scope of influence can be controlled within that drawer, preventing damage to the components in other drawers and improving the safety and reliability of the entire control integration box.

[0022] Further, both the first communication module and the second communication module are wireless communication modules.

[0023] Beneficial effects: The wireless communication module enables the portable operation device to be free from the constraint of cable connection with the low-frequency communication device. The operator can freely move the portable operation device within a certain range to remotely control the low-frequency communication device. Whether operating in a complex terrain environment or in a scenario where the device position needs to be flexibly adjusted, it can be easily achieved, greatly improving the flexibility and convenience of device use. Without the need to lay cables, the installation process of the device is greatly simplified.

[0024] Further, the wireless communication module includes one or more of a WiFi module, a Bluetooth module, a ZigBee module, and a Lora module.

[0025] Beneficial effects: Different wireless communication modules have their own unique advantages, providing diverse communication options. Supporting multiple wireless communication modules enables compatibility with more existing devices and systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is a further detailed description through specific embodiments:

[0029] The markings in the accompanying drawings of the specification include: main body box 1, movable drawer 2.

[0030] Embodiment 1

[0031] A portable wireless through-the-earth communication device, basically asFigure 1 As shown, it includes a portable operation device and a low-frequency communication device;

[0032] The portable operation device includes a first controller, a first communication module and a display module, and the first controller is electrically connected to the first communication module and the display module respectively;

[0033] The low-frequency communication device includes a control integration box, a second controller, a second communication module, a power amplifier, a high-voltage capacitor resonator and a circular transmitting antenna; the second controller, the second communication module, the power amplifier, the high-voltage capacitor resonator and the circular transmitting antenna are all arranged in the control integration box. The control integration box includes a main body box 1 and a movable drawer 2 arranged in the main body box 1. A slide rail is arranged on the inner side wall of the lower end surface of the main body box 1, and a pulley is arranged on the outer side wall of the lower end surface of the movable drawer 2. The movable drawer 2 moves in the main body box 1 through the sliding cooperation of the pulley and the slide rail. In this embodiment, the main body box 1 serves as the main bearing part of the control integration box, and a slide rail is precisely installed on the inner side wall of its lower end surface. The slide rail is made of high-strength stainless steel material and undergoes fine grinding and processing technology, with extremely high surface flatness, ensuring that the movable drawer 2 can slide smoothly. The length of the slide rail is designed according to the size of the main body box 1 and the expected moving range of the movable drawer 2 to ensure that the movable drawer 2 will not derail during the sliding process. A plurality of pulleys are evenly distributed on the outer side wall of the lower end surface of the movable drawer 2. The pulleys are made of wear-resistant polyurethane material with a low friction coefficient, and are equipped with high-precision ball bearings inside, which can greatly reduce the friction force and make the movable drawer 2 slide more smoothly and easily on the slide rail. The size of the movable drawer 2 is adapted to the internal space of the main body box 1, which can ensure that it can accommodate the required components while ensuring free movement in the main body box 1. The four sides of the drawer are sealed to prevent dust and other impurities from entering the drawer interior and affecting the performance of the components.

[0034] The movable drawer 2 realizes its movement in the main body box 1 through the tight cooperation of the pulley and the slide rail. When the user needs to operate the components in the drawer, just gently pull or push the handle set on the drawer (the handle design conforms to ergonomics and is convenient for applying force), and the pulley will roll on the slide rail, driving the drawer to smoothly slide out or into the main body box 1. This sliding cooperation method is not only convenient to operate, but also can form a good sealing effect with the main body box 1 when the drawer is closed, further protecting the internal components.

[0035] The low-frequency communication device includes a second controller, a second communication module, a controllable low-frequency signal source, a power amplifier, a high-voltage capacitive resonator, and a circular transmitting antenna. The second controller is electrically connected to the second communication module and the controllable low-frequency signal source respectively. The output end of the controllable low-frequency signal source is connected to the input end of the power amplifier. The output end of the power amplifier is connected to the input end of the high-voltage capacitive resonator. The output end of the high-voltage capacitive resonator is connected to the circular transmitting antenna.

[0036] The portable operation device and the low-frequency communication device are communicatively connected through the first communication module and the second communication module. Both the first communication module and the second communication module are wireless communication modules. The wireless communication module includes one or more of a WiFi module, a Bluetooth module, a ZigBee module, and a Lora module. In this embodiment, the WiFi module is adopted.

[0037] The first controller in the portable operation device is configured to receive the feedback information of the operator through the display module, generate a corresponding control instruction based on the feedback information received by the display module, and send the instruction to the outside in the form of a wireless signal through the first communication module. At this time, the second controller in the low-frequency communication device is configured to receive the control instruction sent from the first communication module through the second communication module. The second controller is configured to control the opening and closing of the controllable low-frequency signal source according to the received control instruction. When the controllable low-frequency signal source is turned on, the controllable low-frequency signal source emits a signal, which is then processed by the power amplifier and the high-voltage capacitive resonator, and then the low-frequency signal is emitted through the circular transmitting antenna. In this embodiment, the low-frequency signal emitted by the circular transmitting antenna is received by a corresponding receiving end, such as a wireless through-earth initiation device with a receiving antenna. The wireless through-earth initiation device converts the low-frequency signal received by the receiving antenna into a corresponding control signal and detonates the electronic detonator in the wireless through-earth initiation device. In this embodiment, the communication between the wireless through-earth initiation device and the low-frequency communication device is low-frequency electromagnetic wave communication.

[0038] Embodiment 2

[0039] Compared with Embodiment 1, the difference in this embodiment is that the control integrated box includes a main box and a box door. A plurality of push-pull drawers are sequentially arranged in the main box from top to bottom. The second controller, the second communication module, the power amplifier, the high-voltage capacitive resonator, and the circular transmitting antenna are sequentially arranged in each push-pull drawer.

[0040] In this embodiment, different components are placed in different push-pull drawers respectively. When a certain component fails and needs to be maintained, the corresponding drawer can be accurately located. The user only needs to pull out the corresponding drawer to quickly access the target component, greatly shortening the troubleshooting and repair time. For example, if the power amplifier has a problem, the drawer containing it can be directly opened for maintenance without searching among numerous components, improving work efficiency.

[0041] Placing a single or a small number of related components in each drawer helps to carry out targeted design according to the heat dissipation requirements of the components. Independent heat dissipation channels or heat dissipation devices can be set on each drawer to ensure that each component works at an appropriate temperature. At the same time, the drawers are arranged in sequence from top to bottom, making the internal structure of the entire control integration box more regular and orderly, facilitating the connection and management of cables and reducing signal interference.
