Application of wireless uwb positioning chip in underground coal mine positioning system. As a supplier of underground coal mine positioning system, in order to meet the management needs of coal mine enterprises, the precise personnel positioning management system of coal mine has been upgraded again. The system takes wireless uwb positioning chip indoor positioning technology as the core, with positioning accuracy up to 10cm. High stability, high precision, strong anti-interference, larger than one of the coal mine underground positioning system, promote the system upgrade, to achieve the precise positioning of personnel equipment.
The principle of accurate positioning underground coal mine positioning system, coal mine underground positioning system is composed of hardware positioning equipment, positioning engine and application software. Wireless uwb positioning chip positioning system application software supports PC and mobile terminal access, providing real-time location display, historical track playback, personnel attendance, electronic fence, behavior analysis, intelligent inspection and other functions. Positioning accuracy up to 10cm, with high dynamic, high capacity, low power consumption.
The underground positioning system of coal mine places multiple positioning base stations in the underground roadway, and the specific number and location are determined according to the actual situation and functional requirements of the site. The positioning base station is connected to the ground positioning software through the network switch and network wiring. At the same time, each operator must wear identification cards. Once downhole, the signal can be picked up by any location base station and immediately uploaded to the surface monitoring host.
Coal mine underground positioning system wireless uwb positioning chip positioning software can display real-time personnel location, time, identity and other information. Therefore, we can also collect data as needed, understand the distribution of people underground at any time, walking path and access information, scientific management of people.
In case of an underground emergency, the positioning tag worn on the body can be used as a one-click alarm for help. The underground positioning system of the coal mine can quickly notify the management to come to the rescue, provide the accurate location for the personnel in the area in the first time, release the safe escape route, and quickly and accurately rescue.
Advantages of wireless uwb positioning chip underground coal mine positioning system:
1. Automation, after system setting, without manual intervention, can automatically monitor the personnel up and down well time, monitoring point time, stay position, etc., automatically complete the information statistical storage, to achieve attendance management, production management, etc.
2. Fast and accurate communication. After collecting underground personnel data, it is automatically transmitted to the surface through the network server to ensure the accuracy and timeliness of data acquisition by management personnel.
3. Perfect data statistics and query functions. Wireless uwb positioning chip system has a special database management system, which can carry out statistical analysis on the collected data and generate various statistical report information, providing reliable services for personnel management and production management.
4. System stability and reliability design, system products in the harsh environment of the roadway can maintain continuous normal operation, easy installation and maintenance.
The premise of coal mine production safety is to ensure the safety of personnel, effective safety supervision of underground personnel, underground coal mine positioning system can be said to be indispensable. UWB technology has also become a technology to achieve accurate positioning in coal mine.
Design and implement underground coal mine positioning system, coal mining is a high risk industry, the possibility of safety accidents is high. Coal mine underground positioning system can effectively help coal mine enterprises to realize risk management. The mine may set up electronic fence in dangerous areas and important areas to manage employees' rights and prevent employees from entering dangerous areas; Coal mine staff can also conduct behavior monitoring, including overtime monitoring, centralized monitoring, mobile monitoring, comprehensive intelligent management, improve management quality, reduce the occurrence of safety accidents.
Coal mine underground positioning system wireless uwb positioning chip positioning design system, our coal mine underground positioning system has realized the accurate positioning of 10cm. The system adopts advanced UWB transmission and TDOA wireless ranging technology in domestic coal mining industry. According to the underground measurement, the positioning accuracy is less than 10cm, which can also accurately locate the location of personnel in real time in the complex underground environment of coal mine.
Coal mine underground positioning system is mainly used in computer application technology, transmission technology, information transmission technology, real-time monitoring of underground environment and equipment, to achieve the rapid acquisition of relevant data, provide data for managers, and effectively avoid the occurrence of mine accidents.
The design of underground coal mine positioning system needs to set UWB positioning base station in the designated area, and the designated object carries UWB positioning label. The location of the positioning label can be obtained by measuring the distance (or pseudo distance) relationship between the rain positioning base stations.
Wireless uwb positioning chip positioning system makes full use of the characteristics of the physical layer of UWB, at the same hardware cost, innovative multi-base station high-jump precision wireless synchronization. Through high precision wireless synchronization, without increasing the cost of new hardware, the high precision positioning effect is guaranteed, and the system construction and maintenance costs and project implementation costs are greatly reduced.
What are the functions of underground positioning system in coal mine?
1. The underground positioning system of coal mine can realize personnel attendance, and statistics of annual, monthly and daily attendance details of various departments and individuals can provide basis for staff evaluation. Attendance reports and history records can be printed as required. This function can effectively prevent the phenomenon that one person has more than one card.
2, coal mine underground positioning system equipment self-test, the system can check the running state of the equipment at any time, timely detection of equipment failures.
The underground wireless uwb positioning chip positioning system of coal mine has the functions of information storage and query, data storage and action track playback, which provides the basis for accident traceability analysis.
3, coal mine underground positioning system rescue function, in emergency (such as fire, gas explosion, roof fall, penetration, etc.). Personnel can call for rescue through the rescue button on the identification card.
4. Real-time alarm of underground coal mine positioning system, real-time alarm as soon as possible under abnormal circumstances, such as timeout alarm, overmanned alarm, power state alarm, personnel abnormal alarm, etc.
