Description

A wireless identification device for underground mine personnel equipment positioning data transmission

technical field

The utility model relates to a mine signal data transmission device, in particular to a device for identifying identity cards carried by underground personnel equipment and utilizing power line carrier and wireless ad hoc network for positioning data transmission.

Background technique

At present, the most widely used method for the positioning of underground mine personnel and equipment is to install an identifier underground, which only completes the positioning of underground personnel and equipment. The way to realize it is to install the identifier in the roadway and the working surface that need to be positioned underground, and then transmit the positioning data of the identifier to the ground control center by laying optical fiber or communication cable.

However, this method can only be applied to underground mines without any safety accidents. Once the underground transmission cable is interrupted due to accidents, the entire underground mine personnel equipment positioning system will be paralyzed immediately, and the entire system will be paralyzed due to local line failures. The ground cannot be informed Downhole dynamics.

This method itself cannot provide lighting and lighting control. It is not known whether the lighting needs to be turned on or off in some underground areas. If underground lighting is required, an additional lighting system needs to be installed.

This method also requires the laying of communication transmission cables. If the underground mine is a coal mine, all laid cables need to be explosion-proof, and the laying work is relatively difficult.

No matter there is no literature at home and abroad, the use of one instrument has realized the positioning and identification of underground personnel and equipment, the dual data transmission guarantee of wireless ad hoc network data transmission combined with power line carrier data transmission, underground lighting and its lighting control.

In addition, this method is complicated to implement, has a long construction period, and is expensive, and it is not fully utilized for the positioning of personnel and equipment.

Contents of the invention

Aiming at the problems existing in the existing method and equipment for personnel and equipment positioning in underground mines, the utility model proposes an instrument device for underground mine lighting and personnel and equipment positioning and identification that is easy to implement and low in cost.

The specific technical solution adopted to solve the above technical problems is: a wireless identification device for underground mine personnel equipment positioning data transmission, characterized in that: a wireless identification-communication control module is connected to the wireless identification device (5) control circuit board (8) (9) and the power carrier module (10), the control circuit board (8) connects the power supply (12) interface, and the lighting control switch (13) and miner's lamp (11) are housed on the control circuit board (8).

The circuit connection relationship of the wireless identifier is: 1, 3 pins of JP1 in the wireless identification module-communication module (9) are respectively connected with 2, 3 pins of J5 in the control circuit board (8), TXD, RXD in the power carrier module Connect the 2 and 3 pins of J7 in the control circuit board (8).

The beneficial effects of the utility model:

Wear a wireless identity card for all personnel and equipment going down the well. When the downhole personnel enter the mine, as long as they pass or approach any wireless identifier placed in the roadway, the wireless identification sensor will immediately sense the signal, so that the lighting controller will Immediately connect the lighting circuit to provide lighting for the wireless identifier area underground, and upload the signal to the ground control center host through a reliable dual-channel data transmission method, so that the software of the ground control center host can determine specific information (such as: yes Who, at which location, specific time, etc.), and at the same time, it can be displayed on the large screen of the control center and the computer display screen through the GIS system, and the data backup storage is done. When all personnel devices are not within the range of the wireless identifier, that is, the wireless identifier does not recognize any wireless identity card, the lighting controller will immediately disconnect the lighting circuit and turn off the lighting system.

Since the wireless identifier has the function of wireless ad hoc network, one or several wireless identifiers cannot work due to accidents, and will not affect the work of other wireless identifiers, so the entire system will not cause the entire system to fail due to the inability of some wireless identifiers to work. The system is paralyzed.

Since the wireless identifier has the functions of power line carrier communication and wireless communication, as long as one of the two communication methods is in good condition, it can perform data transmission with the ground control system. And there is no need to lay any communication cables underground, as long as there is a power system underground, the reality is that all underground mines have power supply systems. This will greatly reduce the cost of the underground mine personnel equipment positioning system, eliminate the construction of communication cables, shorten the construction period, and greatly reduce the difficulty of system construction.

Since the wireless identifier itself has lighting and a lighting controller, when no personnel equipment is within the range of the wireless identifier, the lighting will be automatically turned off, thereby greatly saving energy. Huge waste.
