　　3.1 2.4G active radio frequency card:

　　Construction workers or workers carry it with them, usually on their belts or helmets. The card has two-way and one-way: the one-way card can only send its own ID number, the two-way card can not only send information to the monitoring center, the monitoring center can also send information to each construction worker, and the two-way card has a button and indicator light. , You can press the emergency button to call for help in case of danger. If the general project is mainly about attendance, it is recommended to use a single card; if the system is mainly about attendance and positioning, it is recommended to use a two-way card. For example: when there is a special situation in the tunnel, the construction staff only needs to press a button, and the monitoring center will sound an alarm. When something happens in the monitoring center, the monitoring center can send a signal to each of the construction workers, or it can send a group message to indicate it through the indicator light.

　　3.2 2.45G long-distance card reader:

　　No matter whether it is inside or outside the tunnel, a card reader needs to be installed. At least 2 units are required in one system. If it's positioning, you need more. The specific installation should be carried out according to the conditions of the tunnel. The general principle is to install one every 150 meters, and it can also be installed in corners and some areas that require special monitoring. The positioning principle of this system is regional positioning, which is based on the position of each reader. Therefore, the accuracy of positioning depends on the recognition distance of the reader. The distance of the reader can be adjusted by software, so the positioning is considered The accuracy should also consider the distance of the card reading and the overall cost of the system. That is to say, the higher the positioning accuracy, the closer the card reading distance is, the higher the cost. Please note!!!!!

　　3.3 RS232/485 converter:

　　The system adopts the RS485 transmission mode. The main function of the converter is to convert the RS485 signal to 232 signal, which is connected to the computer through the serial line.

　　3.4 Wireless bridge:

　　The wireless bridge is used for the wireless transmission of personnel positioning signals in the tunnel and the wireless transmission of the video surveillance system in the tunnel.

　　3.5 Management Center Computer Host:

　　Installed in the monitoring room not far from the tunnel entrance, the computer is equipped with attendance and positioning software, and the construction personnel are monitored through the computer. It is connected to the terminal through a serial port. At the same time, the host computer also controls the display content of the LED screen.

　　3.6 LED display:

　　is installed near the tunnel entrance, used to display the information of the construction personnel, so that the management is advanced and transparent. The displayed content includes: tag number, name, time, total number of people (the screen size is 1.28M*0.8M, the screen can also be larger).

　　3.7 Video surveillance system:

　　Using video software and related drivers to drive hardware cameras, dome cameras and other equipment to exert its infinite potential, the ancient myth "Clairvoyance" is no longer a legend. Through this system, we can spy on everything in the cave at any time.

　　3.9 Other matters

　　(1) The number of card readers and the installation method are determined according to the actual situation of the tunnel site, and the two parties shall negotiate and resolve it.

　　(2) Software function: The function of the system software is developed according to the customer's requirements, please communicate with the software developers of our company before the software development.
