Application Case of Xiupai Technology Tunnel Personnel Management System
chrispeng [ad_1]
1. Basic Concepts
During tunnel operation, it can automatically identify the reading equipment pre-installed in the mine tunnel, and upload the globally unique card number of the identification card to the ground computer system, so that managers can grasp the movement trajectory of personnel at any time, so as to facilitate reasonable scheduling management .
2. Scheme design
The tunnel personnel management system involves computer software, database, electronic circuit, digital communication, wireless identification technology and so on. Therefore, in the design of the scheme, in addition to considering its functions, the stability, reliability, anti-interference ability, fault tolerance and abnormal protection have also been fully considered.The project plan determines to use the existing mature Ethernet plus fieldbus system as the main transmission platform to develop correspondingsensor, personnel wireless identification card and other equipment are connected to the system, and the background data is exchanged with the main system through a standard dedicated database through sensors and special software for attendance management, so as to realize the tracking, positioning and safety management of operators. The overall design of the system is mainly reflected in:
Realize the effective identification and monitoring of the entry and exit of tunnel operators, make the management system fully reflect “humanization, informatization and high automation”, and realize the goal of digital tunnel personnel management.
Provide tunnel management personnel with various management information such as personnel entry and exit restrictions, attendance operations, monitoring and monitoring. Once a safety accident occurs, the special handheld device can immediately detect the work surface within 10-30 meters of the accident site. personnel and their numbers to ensure the efficient operation of emergency rescue and disaster relief and safety rescue work.
System design security, scalability, ease of maintenance and ease of operation.
Easy networking, BS structure, easy to achieve county, city, province and wider area network monitoring.
3. System principle
The Shanghai Xiupai Tunnel Personnel Management System is supported by the main computer of the ground monitoring center, through the data transmission interface and the communication optical/cable laid along the roadway, regularly conducts data inspection and information collection for the installed wireless data sensors. The data sensor will automatically collect the information of the identification card within the effective identification distance, and transmit the relevant data to the ground central station through the transmission network according to the system instructions. After the data information is analyzed and processed, the dynamic distribution of personnel (or moving targets such as locomotives) can be reflected in the main computer interface in real time, so as to realize the purpose of digital management of safety status on the well.
Following the principle of “unified card issuance, unified equipment, and unified management”, the identification card is regarded as a “job permit” or “tunnel access permit”, and the “one person, one card” system is implemented for the personnel who are allowed to work.
According to the mine monitoring requirements, wireless data sensors with the ability to identify the direction of entry and exit and time are installed in tunnels, working faces, etc., and are connected to each other as high-speed industrial Ethernet through the optical fiber data transmission interface, thus forming a complete communication line.
After the tunnel production unit enters the relevant information of the staff, it issues and equips the tunnel staff with identification cards.
The system database records the basic information of the person corresponding to the identification card, including basic information such as name, age, gender, team, type of work, job title, personal photo, and validity period.
The staff who enter the tunnel must carry the identification card with them. When the cardholder passes through the location where the identification system is set, the system will recognize the card number. It is transmitted to the ground monitoring center for data management, and at the same time, prompt information can be displayed on the large geographic information screen wall to display the name of the person passing through. If the sensed wireless identification card number is invalid or enters the restricted channel, the system will automatically alarm, and the on-duty personnel of the security monitoring center will receive the alarm signal and immediately execute the relevant security work management procedures.
The production unit can authorize and manage the identification card according to the production plan. The scope of authorization includes: the tunnel or work surface that the employee can access. In order to prevent irrelevant personnel and illegal personnel from entering the tunnel or working face, the system sets up the card’s access to the tunnel or working face of the aging management module and the card’s failure, reporting the loss, etc.
Once a safety accident occurs in the tunnel, the monitoring center can know the basic situation of the trapped person in the first time. The rescue team uses a mobile long-distance identification device to easily detect the location of the person in distress within a range of 10-30 meters, which is convenient for rescue. The safe and efficient operation of the work facilitates the development of accident rescue work.
The system can automatically generate report data on the statistics and management of attendance operations to improve management efficiency.
4. System function
Real-time personnel dynamic display
Query and display the number, distribution and identity of a place at any time.
Query the current actual location and activity track of one or more people.
Recording a series of information such as the arrival/departure time and total working time of relevant personnel at any location can supervise and confirm whether important inspection personnel conduct on-site inspections on time and at the point, or conduct various data detection and processing, fundamentally Try to avoid related accidents caused by human factors.
Rich personnel tunnel attendance function
It can make statistics on people entering and exiting the well, realize the attendance record of tunnel personnel, and create and print various information reports (such as tunnel time report, monthly attendance report, overtime report, absence report, etc.) and management.
information sharing
The central station of the system and the network terminals can be networked in a local area network, so that all terminals on the network can share information at multiple points within the scope of their use rights, so that various departments and leaders of multiple mines can simultaneously share monitoring information in different places, comprehensively analyze information in the system, and inquire about each other. class data report.
Restricted area alarm function
For the designated restricted area, if an unauthorized person enters, the alarm will sound in real time, and the number and identity of the person entering the restricted area will be displayed.
Disaster first aid information
In the event of various accidents, the host computer can immediately display the number of card-carrying personnel, personnel information, personnel location and other information at the accident location, which greatly improves the rescue efficiency and rescue effect.
Sensor emergency function
When the sensor loses contact with the ground central station, it can still work independently and automatically store personnel monitoring data.
Tunnel personnel identification and one-by-one correspondence function
Shanghai Xiupai’s personnel location detection and attendance system has a special interface function, which can quickly, mass, quickly identify and correspond one by one to the tunnel personnel’s identity to ensure proper management.
