detailed description

The utility model will be described in detail below in conjunction with accompanying drawing, as shown in Fig. 1,2,3,4:

The tunnel construction personnel management system of the utility model includes a personnel positioning information card carried by personnel entering the tunnel, and an RFID positioning label and a UWB positioning label are arranged on the personnel positioning information card; multiple positioning base stations installed in the tunnel hole, according to The actual conditions of the tunnel are installed, and the base station is provided with an RFID receiving module and a UWB receiving module, and performs wireless communication with the RFID positioning label and the UWB positioning label on the personnel positioning information card to obtain personnel positioning information; the server, through wired or wireless The method is connected with the base station to receive and process the personnel positioning information transmitted from the base station; the first display device is used to display the relevant information of the construction personnel. The first display device is connected to the server. The first display device is an LED display screen, which is arranged outside the tunnel hole. There are corresponding unique codes on the RFID positioning label and UWB positioning label on the personnel positioning information card, which correspond to the construction personnel information. The UWB pulse signal sent by the UWB tag is received and transmitted by the positioning base station, and the signal time difference of arrival (TDOA) measurement technology is used to enable the positioning base station to find the actual position of the construction worker carrying the personnel positioning information card through the UWB tag, and the positioning accuracy can reach 10cm. The personnel positioning information card can be set on the safety helmet or work clothes of the construction personnel. The tunnel is divided into areas outside the tunnel, secondary lining construction area, inverted arch construction area, and excavation operation area. The construction risk of construction personnel outside the tunnel is small, and the risk in the secondary lining construction area is relatively small. The risk in the inverted arch construction area is average, and the risk in the excavation operation area is relatively high. , The second lining construction area, the inverted arch construction area, and the excavation operation area are equipped with RFID receiving modules. The RFID positioning tag in the personnel positioning information card sends out data (wireless signal) every few seconds, and these data are received by the surrounding positioning base stations. After data processing, the positioning base station can determine which personnel's positioning information cards are around it. Since the personnel positioning information card is in one-to-one correspondence with the personnel, it is possible to know which personnel are near the positioning base station. At the same time, according to the signal strength of the wireless signal sent by the personnel positioning information card received by the base station, the server can determine how far the person carrying the personnel positioning information card is from the positioning base station, and determine the approximate distance of the person in the tunnel. Location, you can intuitively get the distribution of construction personnel in the tunnel, personnel information, time of entering and exiting the tunnel, and personnel action paths, etc. The display unit is displayed. The positioning base station in the high-risk excavation area is also equipped with a UWB receiving module to accurately locate the personnel near the high-risk area. When an emergency occurs, it can accurately determine the position of the personnel in the high-risk area, which is conducive to emergency management and rescue.
