Abstract

This invention relates to an automatic diagnosing method and automatic failure-reporting device for traffic lights. Without altering the structure of current traffic lights, the device uses a DC power supply, an electric charging system, a rechargeable battery, and a power supply switching circuit to automatically switch the system to the battery power supply so as to keep the system working when the external electrical power is off, and then performs the detection and transmits information.

The signal could be transmitted through wireless communication module to a far-end receiving communication module and then sent to the control center server, which will save the information of failure mode and failure time and send the failure information to the computer of the monitoring personnel via internet so as for displaying and giving voice notification; thereby providing the automatic diagnosing and failure-reporting function to improve the maintenance /troubleshooting rate.

Description

200844915 IX. Description of the invention: [Technical field of invention] The present invention is an automatic automatic diagnosis method for traffic signs and an automatic fault reporting device for constructing a set of fault automatic return devices without affecting the original system architecture. If the traffic signal system is abnormal (such as loss of power, traffic sign, insufficient brightness, ambiguity, incorrect timing of display, etc.), the device will actively detect the immediate negative §fl of the traffic sign. The parent's 5 remote location or number, damage, damage date, etc.) are transmitted to the control center via the Suihua communication device and stored in the database. This message will be displayed on the screen in bold text. And use voice to alert the monitor to the attention. The control center personnel can send personnel to the maintenance according to this message, and after the traffic sign is restored to normal operation, the system will send back the relevant information of the normal operation of the traffic number and store it in the database system for the relevant units to check. Technical field. [Prior Art] Due to the large increase in the demand for densely populated traffic in Taiwan, the density of traffic signs in lanes, sidewalks, level crossings, underground roads, etc. is quite high, but traffic signs are often damaged by natural disasters and system components. Or the effects of aging, man-made damage, etc., resulting in the inability to operate properly, and the traffic conditions on the road sections will be chaotic and car accidents. Under the current traffic signage facilities, damaged traffic signs must be notified by humans, and the maintenance unit can learn and go to repair. Now there is a patent (application number 087219376) traffic number 200844915 system:: judgment and display device, including magnetic field sensing unit 'logic 7g, continuous diagnostic unit, fault display device, etc. ·, when the traffic number has In case of failure, it is marked as a fault by the traffic number under the traffic sign. Under this device, the damaged ship and the ship must pass the artificial notification, and the maintenance unit can be transferred to the front; therefore, Yan Hong has repaired the time and caused traffic chaos and car accidents. [Summary of the Invention] First, solve the problem: 1. The traffic light module loses its function. It may be: 1. 1 The traffic light module loses power: the power company may be powered off, the power line is cut, etc., leading to the entire traffic system. Lose power. 1·2 The traffic light of the traffic light module is insufficient when it is displayed: a. The number of damages on the new type of light-emitting diode traffic sign is too large, resulting in insufficient brightness. ° b• Traditional white heat (or halogen) bulb (Incandescem halogen light bulb) burnt. 1. 3 The traffic light of the traffic light module shows that the timing is disordered, and the scales in the module are different from those of the fixed ones, such as a light surface that is shorter or longer. In the 1·4 traffic light module, the red and green two lights or the red, yellow and green lights are on at the same time. Eight...a 1.5 traffic light module displays the same light number, such as the crossroads and the lights of the two north and south roads display the same color number at the same time, especially when the green lights are displayed on both sides, it will cause Traffic chaos 200844915 with a car accident. Second, the solution: I · The invention of the traffic sign automatic diagnosis system includes: 1) Application Hall device (Hall device) to create a current sensing circuit, the circuit is hooked on the mains power line and the new button, When the mains or the parent is added, the output of the circuit generates a Hall voltage, which can be analogized to the amount of current flowing through the wire. The Hall voltages described in the description are sequentially selected by the analog switches controlled by the microprocessor, processed by the amplification filter circuit, and sent to the analog/digital converter to be converted into digital signals, which are then acquired by the microprocessor. 2. The microprocessor handles the fault diagnosis of the traffic signal based on the acquired digital signal.

3.
