State monitoring method and system for external equipment of terminal, and terminal

Abstract

The invention relates to a state monitoring method and system for external equipment of a terminal, and the terminal. The method includes the following steps: receiving a Heartbeat information packetsent by the external equipment, and storing the Heartbeat information packet into a unique storage space corresponding to the corresponding external equipment; determining time difference between thelast two times when the external equipment sends the Heartbeat information packet according to the sending time of the external equipment in the Heartbeat information packets that are received at thelast two times; and determining an online state of the external equipment according to the time difference. According to the technical scheme provided by the invention, the content of the Heartbeat information packet is simplified, the data storage space of the Heartbeat information packet is saved, and the online monitoring speed of the real-time state of the external equipment is increased; andmeanwhile, the master-slave relationship between the external equipment and the terminal is simplified, the monitoring efficiency of the real-time state of the external equipment is improved, and thecost is reduced.

Description

technical field [0001] The present invention relates to the technical field of state monitoring of demand response resource equipment, in particular to a method for monitoring the state of external equipment connected to a terminal, a terminal and a system thereof. Background technique [0002] The rapid promotion of smart cities and "Internet +" smart energy has greatly promoted the development of smart power consumption services such as smart parks and electric vehicles. There are more and more applications of smart power supply equipment and power consumption equipment such as distributed power supplies and electric vehicles. The demand for these smart power supply equipment and power consumption equipment to be flexibly connected to the smart energy network is increasingly urgent; the emergence of smart power supply equipment and power consumption equipment such as distributed power supplies and electric vehicles has changed the traditional energy exchange mode, making en...

Problems solved by technology

This method sets a parent device, and each parent device monitors the status of several sub-devices. If there is a problem with the parent device, the status of the sub-devices managed by it cannot be monitored, which greatly reduces the reliability of the method; in addition, the method The efficiency is not high, and multiple timers need to be set, which is difficult and error-prone. At the same time, the elements contained in the heartbeat packet are complex and require a larger data storage space
