A video surveillance
Through reasonable wiring, install the dome camera in a place where the site can be monitored. The picture below is the local dome camera installation site of the China Railway 2 Bureau, Qimen North Street, Suzhou Light Rail Line 2.
The images taken by these dome cameras are transmitted to the monitoring room through the video cable, and then displayed on the computer through the video capture card, as shown in the figure below:
Among them, we are also connected to the external network: so that anyone can see it anywhere with an account and password when there is a network, without having to go to the monitoring room.
2. Barrier-free access
When going down the tunnel, install a barrier-free passage at the entrance and exit of the tunnel. It is composed of infrared sensors, alarms, Mulan’s M-2000 card reader and camera. Its working principle is: M-2000 card reader reads the card, infrared If a person is sensed, the alarm switch is turned off and there is no response, but if a person without a card passes through the barrier-free passage, the alarm switch will be closed by reading the card to send an alarm, and the person’s picture will be captured by the camera and displayed on the computer . As shown in the figure:

The computer software shows the condition of the barrier-free passage
Three attendance and display screen
The attendance part is composed of Suzhou Mulan electronic tags, M-5000 card reader, computer, attendance software, and LED display. Its working principle is that the time attendance reader reads the electronic label, transmits it through the RS-485 cable, and transmits the information to the computer through the 485 converter, and the computer displays the information through the LED screen through the software and the network cable as shown in the figure:
Attendance card readers are installed at the entrances and exits of the construction site and the lower base where the construction personnel enter the construction site. The installation location of Qimen North Street in Suzhou is shown in the following figure:

The electronic label is as follows:
Suzhou Mulan Electronic Technology Co., Ltd. (SuZhouMuLanEle & Tec Co., Ltd) is a high-tech enterprise specialized in the strategic research of radio frequency identification (RFID) products. The company is located in the high-tech center of Suzhou High-tech Zone and is a key incubator of the high-tech base of Suzhou High-tech Zone. It has established software and hardware laboratories jointly with Nanjing University of Aeronautics and Astronautics and Southeast University’s electronic laboratory. As a leading and well-known enterprise in the industry, relying on the technical and talent advantages of Nanjing University of Aeronautics and Astronautics and Southeast University, after years of experience and product accumulation, the company has a first-class software and hardware team that can complete long-distance target recognition, data transmission, etc. Product development, production, sales, technical services.
Mulan Electronics’ long-distance radio frequency identification equipment uses the most advanced 0.18uM microwave chip technology, which makes the performance of RFID substantially improved compared with the original microwave technology, and completely solves the problem of long-distance, large flow, and ultra-low power. The identification and data transmission of high-consumption and high-speed moving markers are difficult, and the cost is greatly reduced compared with the past. At the same time, it also solves the fatal weakness of low-frequency electromagnetic wave technology in short sensing distance and poor anti-collision ability. Its various technical indicators are in a leading position in the industry among similar products, opening a new era of long-distance recognition technology.
