Embodiment 1

[0032] Figure 1a It is a flow chart of a signal lamp failure detection method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of performing fault detection on signal lamps. The method can be executed by a signal lamp fault detection device, and the device can be realized by software and / or hardware. see Figure 1a , a signal lamp failure detection method provided in this embodiment includes:

[0033] S110. Obtain operating parameters of the signal lamp to be detected.

[0034] Wherein, the signal light to be detected is a traffic signal light at an intersection. The operating parameters are parameters during the operation of the signal lamp.

[0035] Typically, the operating parameters include: at least one of the change value of the parameter detection device and the maximum value, minimum value, difference value and average value of the parameter, wherein the parameters include current, voltage, active power, reactive pow...

Embodiment 2

[0050] figure 2 It is a flow chart of a signal lamp failure detection method provided by Embodiment 2 of the present invention. This embodiment proposes a method for judging a partial fault state based on the foregoing embodiments, taking the fault state as an example of a partial fault state as an example. see figure 2 , the signal detection method provided in this embodiment includes:

[0051] S210. Obtain operating parameters of the signal lamp to be detected.

[0052] S220. Determine the difference between the operating parameter and the operating parameter in a normal operating state.

[0053] S230. Determine, according to the difference, a change ratio of the operating parameter relative to an operating parameter in a normal operating state.

[0054] S240. Determine the number of damaged paths of the signal lamp to be detected according to the change ratio.

[0055]Usually, the signal light is composed of three street lights, which are red light, green light and y...

Embodiment 3

[0069] Figure 3a It is a flow chart of a signal lamp failure detection method provided by Embodiment 3 of the present invention. This embodiment is an optional solution proposed on the basis of the above embodiments in combination with factors of different working states of the signal lights. see Figure 3a , a signal lamp failure detection method provided in this embodiment includes:

[0070] S310. Obtain operating parameters of the signal lamp to be detected.

[0071] S320. Determine the working state of the signal lamp to be detected.

[0072] Wherein, the working state is always on and off state, blinking state or countdown state.

[0073] The manner of determining the working state of the signal lamp to be detected may be determined according to operating parameters, or may be determined according to the change law of the working state of the signal lamp and the current time.

[0074] S330. Determine the operating rule of the signal light according to the working st...

Abstract

The embodiment of the invention discloses a signal lamp fault detection method, device, equipment and medium, and relates to the field of traffic signal lamps. The method comprises the steps of obtaining operation parameters of a signal lamp to be detected; according to the operation parameters and pre-learned signal lamp operation rules, determining whether the operation state of the signal lampto be detected is in the fault state or the fault risk state. According to the signal lamp fault detection method, device, equipment and medium, the operation state of the signal lamp is automaticallyjudged.

Description

technical field [0001] The embodiments of the present invention relate to the field of traffic lights, and in particular to a signal light failure detection method, device, equipment and medium. Background technique [0002] With the development of social economy, urban traffic problems have attracted more and more attention. The correct setting and stable operation of traffic lights are the basis for ensuring smooth and safe road traffic. Therefore, the management of signal lamp failure is particularly important. [0003] At present, the fault detection of traffic lights still stays in the three ways of on-duty traffic alarm repair, traffic facility unit inspection and repair, and citizen alarm. [0004] However, the above-mentioned fault detection method has the problems of poor real-time performance of fault discovery, delay of repair report information and lag of emergency repair work. Contents of the invention [0005] Embodiments of the present invention provide a...
