Abstract

The invention relates to the alarming field, and particularly relates to a network transmission equipment power failure alarming system and a method in network video monitoring. The system comprises network management equipment, the network transmission equipment and a client, wherein the network transmission equipment comprises a power supply module and a CPU, the CPU generates at least one equipment power failure alarming Ethernet data packet, and before complete network transmission equipment power failure, the equipment power failure alarming Ethernet data packet is sent to the Ethernet management equipment; the network management equipment analyzes the power failure alarming Ethernet data packet sent by the CPU and sends an analyzing result to the client, and the client monitors the network transmission equipment power failure alarming state. No special worker needs to be in a project site to detect the equipment power failure problem; the real-time monitoring effects are achieved, and alarming is quicker and more efficiently; and the communication resources of the network equipment are made full use of, and the video monitoring system maintenance cost is reduced.

Description

technical field

[0001] The invention relates to the alarm field, in particular to a power-down alarm system for network transmission equipment in network video monitoring. Background technique

[0002] When building a video surveillance communication network, many factors will cause the communication between the remote network transmission equipment and the monitoring center to be disconnected. One of the more common factors is that the power of the network equipment is disconnected and the equipment does not work, but there are also other factors that cause this situation, such as fiber breaks, excessive optical attenuation, equipment software errors, and so on. Because there are many reasons for disconnection of network devices, and the on-site engineering environment is complex, professional maintenance personnel are usually required to check one by one. Especially going to the engineering site to check the power failure factors takes a lot of time, thus increasing the m...

Embodiment Construction

[0020] The invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Please refer to figure 1 , the present invention is a network transmission equipment power failure alarm system in network video monitoring, which specifically includes network management equipment, network transmission equipment and a client.

[0021] The network transmission equipment includes a power supply module and a CPU. The power supply module compares the input voltage with a predetermined reference voltage. If the input voltage is lower than the predetermined reference voltage, it judges that the network transmission equipment is about to be powered off. At this time, the power module sends a power-off interrupt signal. At this time, the device has not been completely powered off, and it can still work for a short period of time, generally more than 100ms, until the device is completely powered off, and the device stops working at this time. ...
