Problems solved by technology

[0004] In this way, when a gateway fails or enters a full load state due to receiving monitoring data sent by multiple data collection terminals at the same time, one or more data collection terminals corresponding to the gateway may not be able to access the gateway, resulting in The corresponding data collection terminal cannot upload the monitoring data collected by it in time

Abstract

The invention discloses a communication method, a data acquisition terminal and a monitoring system, and the method is applied to the data acquisition terminal of the monitoring system, and comprisesthe steps: A0, pre-storing at least two frequency points; A1, selecting a current frequency point which is not selected from the at least two stored frequency points; A2, broadcasting a networking request according to the current frequency point; A3, detecting whether a networking response message is received within a first set time period after the networking request is broadcasted, sending the networking response message by an access gateway corresponding to the current frequency point in the monitoring system, and if so, executing A4; Otherwise, executing A1; And A4, establishing a communication connection with the access gateway, and sending monitoring data to the access gateway according to the current frequency point. Through the technical scheme provided by the invention, it can beensured that the data acquisition terminal of the monitoring system can upload the monitoring data in time.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method, a data collection terminal and a monitoring system. Background technique [0002] The monitoring system usually includes a central control platform, multiple gateways, and multiple data collection terminals. Each gateway is connected to the central control platform. When the density of data collection terminals is high, each gateway needs to be connected to multiple data collection terminals. [0003] At present, the access mode between each gateway and data collection terminal in the monitoring system is fixed networking, that is, a data collection terminal can only request networking and send monitoring data according to the set frequency point corresponding to the gateway with the set frequency point. [0004] In this way, when a gateway fails or enters a full load state due to receiving monitoring data sent by multiple data collection terminals a...
