Monitoring method, device and equipment

Abstract

The invention relates to the field of computer application and discloses a monitoring method, a device and equipment. In the monitoring method disclosed by the invention, a monitoring terminal generates a first data request instruction; after a gateway receives the first data request instruction, the read electrical equipment parameter information is transmitted to the monitoring terminal; the current parameter information of the electrical equipment is read each preset first time period later, the current parameter information is compared with the latest-stored parameter information, and the current parameter information is transmitted to the monitoring terminal until the current parameter information is different from the latest-stored parameter information. Thus, in the method, through a one-request multi-reply mechanism, data are only transmitted when the content of the data changes, data interaction between the gateway and the monitoring terminal is reduced, flow can be effectively saved, and network burden is lessened.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a monitoring method, device and equipment. Background technique [0002] The monitoring system is an industrial remote monitoring system. For example, using the air-conditioning monitoring system, various parameters of the air-conditioning host and piping system can be remotely and centrally monitored through the computer. Therefore, in order to ensure the stable operation of electrical equipment, the monitoring system has been widely used. [0003] Existing monitoring systems generally consist of a monitoring terminal, a gateway and electrical equipment. The monitoring terminal is connected to the gateway, and the gateway is connected to the electrical equipment, and monitors the electrical equipment using roll call and reply mechanisms. Among them, the roll call and reply mechanism means that when the monitoring terminal needs the parameter information of the electrical eq...

Problems solved by technology

[0004] However, the inventor found in the research process of this application that when monitoring electrical equipment in the prior art, the mechanism of roll call and reply is adopted, see figure 1 In the information interaction diagram shown, in order to grasp the operation status of the electrical equipment, the monitoring terminal needs to send request information to the gateway at regular intervals. After receiving the request information, the gateway obtains the parameter information of the electrical equipment and transmits it to The monitoring terminal, that is to say, in the monitoring process, it is necessary to repeatedly exchange information between the monitoring terminal and the gateway to obtain the parameter information of the electrical equipment, which requires a large amount of traffic, thus bringing a large burden to the network , and even cause the entire network to be blocked
