Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a precise positioning card reading device for mining. Background Art

[0002] With the orderly advancement of intelligent coal mine construction, each mine takes coal mine safety as the starting point and relies on various types of intelligent precise positioning equipment to achieve precise positioning from people to vehicles and then to equipment. In particular, precise positioning of personnel based on ultra-wideband wireless communication technology (Ultra Wideband, UWB) has been widely promoted and applied, enabling the precise positioning of underground personnel, greatly improving the management efficiency of mine personnel and improving production efficiency.

[0003] With the widespread application of UWB underground, location-based applications and services, precise positioning equipment is becoming more and more widely used in coal mine production. In order to achieve precise positioning underground, card readers need to be deployed underground.

[0004] However, the existing UWB precise positioning equipment has the following problems: integrated base stations, card reading substations, card readers and other equipment often use metal casings, which have a shielding effect on UWB wireless signals and require external antennas through feeders. In order to meet the actual coverage requirements, directional board-mounted antennas are often used. In this way, the device plus the antenna makes the overall volume very large and the cost is relatively high. In actual installation, in order to monitor some points, it is necessary to expand and add a positioning card reading device without increasing the power supply. Conventional card reading devices often have multiple card reading boards built in, which consume a lot of power and are not suitable for positioning blind spots. At the same time, since the RF part and the antenna are independent, they often need to be installed separately in actual installation. Brackets, especially in special workplaces, often need to be moved frequently. Installation in such scenarios takes up time and reduces work efficiency.

[0005] Therefore, it is necessary to develop a new type of mining precise positioning card reading device to solve the above problems existing in the prior art. Utility Model Content

[0011] A terminal board is disposed in the third cavity and is electrically connected to the control module for external connection.

[0012] The beneficial effect of the precise positioning card reader device for mining provided by the utility model is that: by dividing the shell into a first cavity, a second cavity and a third cavity, the antenna is placed in the first cavity, the board is placed in the second cavity, and the terminal board is placed in the third cavity, thereby realizing an integrated design of the card reader antenna, and there is no need to consider the installation of the antenna during the actual installation process, which greatly facilitates the engineering construction; and a separate third cavity is used as a wiring cavity, which facilitates on-site wiring while ensuring that the product protection is not changed.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The existing various types of fusion base stations, card reading substations, card readers, etc., all have the card reading function, but require additional supporting antennas. In order to solve the problems that these devices and supporting antennas are large in size, relatively high in cost, and the products are not suitable for positioning blind expansion and long-distance power supply, the utility model proposes a mining precise positioning card reading device that integrates the board card and the antenna. The overall equipment is compact, integrated, and platform-based, meeting the needs of base station expansion positioning coverage.

[0031] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides a precise positioning card reader device for mining, including a shell 1, an antenna 2, a board 3 and a terminal board 4. Antenna 2 is used to receive or transmit wireless signals. Board 3 integrates multiple functions. Terminal board 4 facilitates various wiring. The interior of shell 1 is composed of a first cavity, a second cavity and a third cavity 7. Antenna 2 is arranged in the first cavity. Board 3 is arranged in the second cavity, and board 3 includes a display module, a control module and a UWB radio frequency module. The control module is electrically connected to the display module and the UWB radio frequency module, respectively, and the UWB radio frequency module is electrically connected to the antenna. The terminal board 4 is arranged in the third cavity 7 and is electrically connected to the control module for external connection.

[0032] By dividing the interior of the shell 1 into a first cavity, a second cavity and a third cavity 7, that is, the interior space of the shell 1 is reasonably divided, the layout design is reasonable. The antenna, board and terminal board are designed at the same time in the same shell 1 to realize the integration of the card reader antenna. At the same time, the wiring requirements are met, the volume of the overall equipment is reduced, and the production cost is reduced. The shell 1 is designed with an open mold, and the corresponding shell 1 can be disassembled according to the actual installation requirements, which is convenient for installation. At the same time, in order to ensure reliable protection, a dual-cavity design is adopted, which includes a second cavity for placing the board 3 and a third cavity 7 for placing the terminal board 4. The interface on the terminal board 4 adopts a one-in-one-out method, which is convenient for serial connection and cascading. When wiring, only the third cavity 7 (i.e., the wiring cavity) needs to be opened. The second cavity for placing the board 3 is disassembled, and the second cavity and the third cavity 7 are connected by pouring.

[0033] In some embodiments of the utility model, a bracket for mounting antenna 2 is provided in the first cavity to facilitate the installation of antenna 2. Antenna 2 is, for example, a flat antenna, which propagates only in a specific direction, improving the directivity of antenna 2 and being able to read tags worn by people at a longer distance.

[0034] like Figure 2As shown, in some embodiments of the utility model, the board 3 also includes a power supply module. The power supply module is connected to the control module. In order to facilitate long-distance expansion applications, the board 3 is a miniaturized integrated design. A low-power chip solution is adopted, and the overall power consumption is less than 3W. The power supply adopts a wide voltage power supply, that is, DC5-24V is selected, and the current is less than 300mA. The overall power consumption of the utility model is small, and it can meet the needs of expanding and adding positioning card reading devices without increasing the power supply. It is suitable for positioning blind spots and greatly improves the positioning efficiency.

[0035] like Figure 1 and Figure 3 As shown, in some embodiments of the utility model, the precise positioning card reader device for mining further includes a display screen 5. The display screen 5 is connected to the display module and is detachably connected to the housing.

[0036] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the display screen 5 is an OLED display screen. The use of an organic light-emitting diode (OLED) display screen has low cost and ensures low power consumption design requirements.

[0037] like Figure 2 As shown, in some embodiments of the utility model, a CAN interface and / or an RS-485 interface are provided on the terminal board 4. The communication interface adopts a bus interface that can be transmitted over long distances. For ease of application, a controller area network (CAN) interface and / or an RS-485 interface are selected. These two types of bus interfaces are modular and can be selected as needed in actual use.

[0038] like Figure 2 As shown, in some embodiments of the utility model, the board 3 reserves the RJ45 reading or debugging board function. That is, the terminal board 4 is provided with an RJ-45 interface, which can be used to connect the RJ-45 connector and is suitable for a network constructed by a twisted pair. Generally, an Ethernet hub will provide such a port. Or the terminal board 4 is also provided with a debugging interface, and the setting of the debugging interface facilitates the R&D personnel or the user to locate and repair the problems that occur, so as to quickly find the problems and propose solutions to the problems in a timely manner.

[0039] like Figure 2-Figure 3As shown, in some embodiments of the utility model, the second cavity and the third cavity 7 are arranged side by side. An isolation plate 8 is arranged between the first cavity and the second cavity and the third cavity 7. That is, the second cavity and the third cavity are set as the front cavity, the first cavity is set as the rear cavity, and an isolation plate 8 is set between the front cavity and the rear cavity. The material of this isolation plate 8 is metal. The purpose of setting the isolation plate 8 is to improve the directivity of the antenna 2 and isolate the mutual interference of the signals of the antenna 2 and the card 3. A metal shielding plate is added to isolate the interference, so that the card reading antenna can be integrated at the same time without interfering with each other. The third cavity 7 is a wiring cavity. The separate wiring cavity facilitates on-site wiring while ensuring that the protection is not changed.

[0040] like Figure 1-Figure 2 and Figure 4 As shown, in some embodiments of the utility model, the mining precise positioning card reader device further includes an aviation plug 6. The aviation plug 6 is arranged on one side of the housing 1. That is, two aviation plugs 6 are arranged at the lower end of the housing 1. The use of the aviation plug 6 has the advantages of safety and reliability, avoiding wrong wiring, and being waterproof and dustproof.

[0041] like Figure 1 and Figure 3-Figure 4 As shown, in some embodiments of the utility model, the shell 1 includes a first shell 11, a second shell 12 and a third shell 13. The first shell 11, the second shell 12 and the third shell 13 are detachably connected in pairs. That is, the second shell 12 and the third shell 13 are set as front covers, and the first shell 11 is set as a back cover. The front cover and the back cover adopt an open mold design shell. It should be noted that the first shell 11, the second shell 12 and the third shell 13 jointly surround the inner cavity of the shell 1, wherein the inner cavity corresponding to the first shell 11 is the first cavity, the inner cavity corresponding to the second shell 12 is the second cavity, and the inner cavity corresponding to the third shell 13 is the third cavity 7. Since the first shell 11, the second shell 12 and the third shell 13 are designed to be detachable in pairs, only one device needs to be moved when installing or moving, that is, the corresponding inner cavity can be opened, which facilitates installation and improves installation efficiency.

[0042] In some embodiments of the present invention, the material of the housing 1 is acrylonitrile-butadiene-styrene copolymer, that is, the material of the entire shell is acrylonitrile-butadiene-styrene copolymer (ABS), which ensures that the UWB signal of the antenna 2 inside the housing 1 is not shielded.

[0043] like Figure 5As shown, the board 3 must also meet the positioning card reading function. The board reader can read the surrounding tag information. The tag can store the positioning data for about 8 hours (200 tags) offline, that is, the antenna 2 receives the signal of the positioning tag device, transmits this signal to the UWB radio frequency module of the board 3, and after measuring the distance, uploads it to the base station or transmission substation and then uploads it to the server through the bus interface, that is, the CAN interface and / or RS-485 interface of the terminal board 4, so as to obtain the positioning related information of the personnel. At the same time, the utility model supports the display of voltage, tag ID, other module information and user-defined information through the display screen 5 after local card reading.

[0044] It should be noted that the front and back in this article refer to Figure 1 Before and after shown.

[0045] In summary, the size of the overall device of the utility model is similar to that of a flat antenna, so the card reading function can be realized, which greatly reduces the volume of the card reading device. Moreover, in actual installation, there is no need to consider how to install the antenna, which greatly facilitates the engineering construction, especially the use of the third cavity 7 (wiring cavity) alone, which facilitates on-site wiring while ensuring that the product protection remains unchanged. At the same time, the board adopts a low-power consumption and bus interface solution, and there is no need to deploy a power supply locally, so as to realize long-distance extension of communication and power lines. A multi-polarized antenna vibrator is built into the shell, and a metal shielding plate is used for isolation between the board and the antenna. On the basis of meeting the performance requirements, the installation of components is reduced, which greatly reduces the production cost.

[0046] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
