Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings:

[0018] like figure 1 As shown, the tunnel GPS timer consists of a GPS antenna, a GPS module, a single-chip microcomputer as the main control, a battery monitoring circuit, and a wireless communication module. The single-chip microcomputer as the main control communicates with the GPS module through the interface, can read the satellite positioning information and time, and send the time to the remote control host device in the tunnel through the wireless communication module. The battery monitoring circuit collects the voltage of the power supply battery, and converts the data collected by the voltage into a digital signal that can be recognized by the single-chip microcomputer through the A / D conversion circuit (LM358) and sends it to the single-chip computer. The single-chip microcomputer and the wireless communication module are connected by a serial port, which ca...

Abstract

The invention discloses a tunnel GPS time calibration device. The tunnel GPS time calibration device comprises a single-chip microcomputer, a GPS module, a GPS antenna, a wireless communication module and a battery monitoring circuit. The GPS module, the wireless communication module and the battery monitoring circuit are respectively connected with the single-chip microcomputer. The GPS antenna is connected with the GPS module. The wireless GPS time calibration device is realized so that time calibration of various control hosts in the tunnel can be performed, the constraint of the wiring requirement of the GPS time calibration device in the tunnel can be relieved, and tunnel construction cost can be reduced. When multiple sets of host equipment in one tunnel is calibrated, the accurate time basis can be provided for long-time operation of the host equipment in the tunnel, and the further optimized scheme can be provided for realization of intelligent control of the equipment in the tunnel. Monitoring data of battery voltage can be provided because of battery voltage monitoring. When voltage is undersized, alarm prompting can be performed so that great basis can be provided for later maintenance of the equipment, and workload of maintenance of the equipment in the tunnel can be greatly reduced.

Description

technical field [0001] The invention relates to a GPS timer used for security alarm, in particular to a tunnel GPS timer. Background technique [0002] Because GPS time-checkers are mostly used in open areas, the time-checking of the control host in the existing tunnel is mostly carried out by wired network. This method exists: when the wired network fails, it may cause the system time of the control host in the tunnel to be disordered, resulting in the failure of calibration, and the light control in the tunnel may be abnormal. The timing calibration time of the GPS timer is generally fixed by the GPS timer and cannot be modified. SUMMARY OF THE INVENTION [0003] In view of the above state of the art, the purpose of the present invention is to design a GPS timer applied to a tunnel. [0004] Realize the wireless time calibration of the control host in the tunnel; realize the remote monitoring of the battery voltage of the wireless GPS calibration device; realize the re...
