Solution: WATCHERMINE Coal Mine Safety System

The digital inputs in the riot box can receive alarms/triggers from the equipment, such as monitoring the status of the equipment. The digital output can remotely turn on/off the lights or turn on/off the ventilation door. WATCHERMINE displays the status of on-site equipment in a graphical manner, reducing manual operations. Different icons represent different equipment and different operating states, and the location information of people and objects is also displayed graphically.

Monitor and manage different areas underground according to the movement of personnel and assets and the registration in different areas

At all entrances, people and assets can be monitored using tags or video recording. For example, the camera can capture the movement of people and assets, and can remotely monitor people and assets based on automatically recorded video recordings. It can also monitor riot-prone warehouses.

Install the reader on the mobile device and complete the relevant settings. Within a range of 30-100 meters, when a person carrying a tag enters the area, the mobile device will automatically stop to avoid hurting the person. At the same time, the system also pays attention to those who enter the area without permission. The system will further identify persons who illegally enter a certain area and take corresponding measures. For example, recording the information of the illegal entry and the time information at the time, as well as the normal entry and exit management information.

It is very convenient to use the handheld and can deal with different situations. For example, a walking staff can hold a hand-held machine to quickly obtain the general status of all team members or staff in a certain area. After integrating the PTW (Work Permit) system, PDA can be used to ensure that all miners working in a certain area are permitted miners and are qualified to work in this area.

The tag can be tied to the miner’s belt, can be attached to the mine cap, can be hung on the ankle and wrist, or can be placed in the car. The label is completely sealed and can be cleaned at a temperature of 90°C. People, vehicles and other assets can be equipped with the same tags. You can choose labels of different colors, such as wearing red labels for guests, so that you can easily distinguish between foreigners and miners.

It is possible to monitor personnel, charging equipment, IT loading and the location of the vehicle from the same user interface. For example, after assets and personnel change locations, quickly searching for equipment and important personnel can save valuable time. When registering a tag in the system, you can create a custom form to write different information for different types of tags.

For example, for a person’s tag, information about relatives, health status, and current certificates can be written. For the vehicle tag, write information such as the maintenance interval, the type of engine, and the year of purchase. Our quotation should include a synchronization service that allows users to use and retrieve synchronized existing personnel information from the existing database system without having to retype any information.

SMS (Storage Management Service) alarm When the reader is disconnected from the system, UPS supplies power to the riot box, and personnel or assets enter an area without permission, the alarm device in the system alarm will be automatically triggered. Send alarms to mine managers, OH&S (Occupational Health and Safety) engineers, ESO (Emergency Service Workers) or other related personnel via email or SMS.

The LED display screen dynamically displays relevant information. Workers can see the information through the LED display screen, and can also see the name of each miner who wears a tag (when the tag is read). When using the system at the main entrance, a special LED display that can display 20 road information is used, so that the miners can sit on the bus and pass through the entrance. If a certain miner is randomly selected by the system for drug and alcohol testing, or the battery of a certain label is low (the battery life is generally 4 years), similar information will also be displayed on the LED display. You can also see how many people are in a particular area.

If you need to add an antenna, a new software module or reintegrate, all components can be added or removed from the system without affecting other components. This is very important, because if something goes wrong inside a software module, it will only affect this module and not the entire system.

High-speed, reliable, long-distance reading and writing

The communication range between the tag and the antenna is up to 100 meters, and a bus carrying 30 people can still be read even if it passes by at high speed. A reader can read 2000 tags at the same time. If the reader loses the connection with the server, it can also store up to 2000 unique reading records through an internal buffer. When the connection is restored, these records can be renewed. Pass it to the server.

If the current mine uses optical fibers, it is very normal that there are only optical fibers in the main shaft. We use a very small, low-cost remote communication box. There is a pair of readers connected to the antenna in the box. The adjacent boxes are connected by standard CAT5 cables. The farthest distance can reach 1000 meters. The remote communication box is powered by Ethernet. For some places that have been proven to increase additional costs, there is no need to extend optical fibers or cables, but only need to divide the entire mine into different areas.
