Project background

The active 433MHz downhole personnel attendance and positioning management solution launched by Jiangsu Tangan is a comprehensive application system that integrates downhole personnel attendance, tracking and positioning, post-disaster first aid, and daily management.The system uses the corresponding mine personnel tracking and positioning equipment, real-time automatic tracking and attendance of the personnel entering the well around the clock, keeping track of the location and activity trajectory of each employee underground, and grasping the location distribution of the underground personnel at any time, so as to ensure the safe production and daily life of the enterprise. Improve management and serve as a reliable command basis for emergency first aid

Solution advantage

1. 433MHz activeRFIDThe technology has the characteristics of strong penetration, strong diffraction, and long transmission distance, and is suitable for various complex environments.

2. In view of the penetrability and strong diffraction of 433MHz, the electronic tag can be affixed to the helmet or hung on the chest in the form of a badge, and can also be placed in a clothes pocket, which is convenient to carry.

3. 433MHz active RFID has an RSSI signal strength indicator function, which can judge the distance based on the RSSI signal strength.

4. Strong diffraction, which solves the problem that other RFID technologies are easy to block each other’s signals among batch personnel.

5. Automatic long-distance recognition, long reading distance (adjustable from 1 to 150 meters), no need to close to swipe the card, just follow the normal path to enter and exit to identify, suitable for batch personnel to quickly pass identification at the same time (speed at 200KM/H Can be effectively identified within).

6. If you want to manage engineering vehicles, equipment, etc., you only need to install electronic tags on the vehicles and equipment, and the reader can recognize them at the same time.

7. Ultra-low power consumption, no radiation damage, safe and reliable use.

8. Due to the powerful long-distance characteristics of 433MHz RFID, giveHandheldThe application is very convenient. For emergency evacuation drills, etc., you only need to use a smart phone with a portable Bluetooth reader to scan the information of the people in place at the assembly point, which is convenient for the emergency evacuation of personnel.

9. For collapses and other accidents, smart phones can also be used with portable Bluetooth readers to check the information of trapped persons to improve the efficiency of accident rescue.

Scheme principle

The system consists of “application software server”, “monitoring computer”, “RFIDReader”And “RFID electronic tags”.

1. Working principle:

Allocate “RFID electronic tags” to each employee, realizing one person, one card. Install “RFID readers” in sections in the mine, distribute management computers and install management software in the duty room.

When personnel pass through different sections of the mine, the corresponding “RFID reader” obtains the “RFID electronic tag” signal and transmits the signal to the monitoring computer, and the monitoring computer can learn the current personnel information and personnel location status.

System functions

1. Personnel positioning: display the location and time of personnel in real time.

2. Staff attendance:

3. Inquiry and statistics of attendance records.

4. Online leave application and approval functions on the management terminal.

5. Query the current location and historical location of employees online

6. Display of dynamic positioning map
