Abstract
Description
technical field
[0001] The invention relates to the technical field of safety management, in particular to a radio frequency identification-based positioning management system for electric foundation pit operators. Background technique
[0002] At present, the safety production situation of deep foundation pit operation in the domestic electric power industry is severe, and the state pays more and more attention to these problems. In order to effectively improve the safety production management capability of the electric power deep foundation pit, it is necessary to strengthen the supervision of the construction personnel in the pit, to know the location of the personnel and safety communication well, and to follow up the production progress in time. The existing electric power deep foundation pit construction personnel monitoring equipment can only detect the environmental conditions, and the personnel positioning system mostly uses RHS or RS485 transmission, the method is ...
Examples
Embodiment 1
[0045] Such as figure 1 As shown, the present embodiment provides a radio frequency identification-based electric power foundation pit operator positioning management system including a surface monitoring host unit 1, and the ground surface monitoring host unit 1 includes a remote computer, and a transmission device set on the remote computer. Interface, the transmission unit 2 connected with the transmission interface, the transmission unit 2 is connected to the data information collection node 3 arranged at different elevations in the foundation pit, the data information collection node 3 includes a reader 31, a gas detector 32, the The reader 31 passes The way of wireless transmission An active RFID electronic tag 4 is connected, and the active RFID electronic tag 4 is arranged on the safety helmet.
[0046] The program set in the remote computer includes a control terminal unit, a location management unit, a data transmission protocol unit, a time correction unit, and a ...
Embodiment 2
[0063] Such as Image 6 Shown, its difference with embodiment one is:
[0064] The data information collection node 3 includes three groups of readers 31, and the three groups of readers 31 are not in the same plane.
[0065] The clock set on the reader 31 is a high-precision clock source, including an atomic clock.
[0066] Three sets of relative distance coordinates are obtained on the basis of the time difference of the same information received by the three sets of readers 31, and three sets of spatial positioning are carried out according to the relative positions of the three sets of readers 31 to determine the relative space of the active RFID electronic tag 4 coordinate.
[0067] It is suitable for special environments with inconsistent signal attenuation such as mineral veins and rock blocking in foundation pits. Relying on the traditional gas detector 32 to find the average value method is likely to cause great deviations, false alarms for personnel positioning, an...
Embodiment 3
[0070] It differs from Embodiment 1 in that:
[0071] An alarm signal transmission protocol is set on the active RFID electronic tag 4 .
[0072] The alarm signal transmission protocol includes alarm warning codes, location information, and alarm content.
[0073] The alarm signal transmission protocol is a broadcast transmission protocol command when actively sending out an alarm signal, that is, when all devices on the same platform that receive the alarm signal retrieve the communication code of the alarm signal for the first time, on the basis of marking the identification code of the device, The alarm signal is automatically rebroadcasted at regular intervals until the warning code corresponding to the alarm instruction received by the surface monitoring host unit 1 is detected, and the alarm signal transmission protocol is released.
