Method for monitoring power supply state, server and system

Abstract

The invention relates to a method for monitoring a power supply state, a server and a system, and the method is characterized by comprising the steps: obtaining a residual electric quantity value of apower supply module, and the power supply module is used for supplying operation of an image collection device; determining whether the residual electric quantity value is smaller than a first threshold; and if yes, reducing the image acquisition frequency for controlling the image acquisition device so as to save the power consumption of the power supply module. The image acquisition frequency of the corresponding image acquisition device is automatically adjusted by monitoring the residual electric quantity condition of the power supply module, so that the image acquisition device intelligently adjusts the image acquisition frequency along with the residual electric quantity of the power supply module, and the balance between the residual electric quantity of the power supply module andthe monitoring effect of the image acquisition device is achieved. Therefore, the method can be widely applied to the technical field of parking management.

Description

technical field [0001] The invention relates to the technical field of parking management, in particular to a method, server and system for monitoring power supply status. Background technique [0002] In order to standardize the management of urban street parking, the following three forms are usually adopted: [0003] 1. Adopt the inspection form of parking lot inspection management personnel: [0004] The parking space inspection management personnel are used to inspect the parking spaces at time intervals (for example, 15 minutes) and record the entry, departure time, charges, etc. of the vehicles. This method requires a lot of manpower, and the manual method has low efficiency and inaccurate billing. [0005] 2. Geomagnetic parking fee form: [0006] Geomagnetic parking charges are based on the installation of geomagnetism under the road corresponding to each parking space, which is easy to install. However, geomagnetism can only identify whether there is a vehicle o...

AI Technical Summary

Problems solved by technology

[0009] (1) Vulnerable: Since the video piles are generally set on one side of the parking space along the length direction, the height is usually 80cm-120cm, which is relatively short, so it is easy to damage the video piles during the parking process. In addition, there are also artificial damage to the video Pile to evade payment;

[0010] (2) Easy to block: due to its short height, it is easy to artificially or accidentally set up some blocking objects on it, resulting in the inability to identify parking, etc.;

[0011] (3) High cost: the video post is an integrated device that integrates multiple devices, so the cost is very high. Once it is damaged, the maintenance cost is high

[0014] In order to monitor on-street parking spaces with high-position camera devices, the support of power supply equipment is required. However, at present, the power supply cables in various cities are fixed. The power supply used to realize on-street parking monitoring requires large-scale construction, such as laying cables, etc. , not only is the construction difficult and expensive, but also affects urban traffic and brings great inconvenience to the public

[0015] Therefore, it is the first choice to use batteries for power supply for camera devices. However, using batteries for power supply requires a lot of manual maintenance, so a lot of post-maintenance costs are required.
