Abstract

The invention discloses a communication method, equipment slaves, a building equipment management system and a storage medium. The communication method is used for the equipment slaves, and a plurality of equipment slaves are connected with a BMS host through physical channels; the communication method comprises the following steps: judging whether a BMS request message sent by a BMS host is received within a preset duration or not every other preset duration; if so, generating a BMS response message and an autonomous message according to the BMS request message; and adding the autonomous message to the BMS response message, generating a comprehensive message, and sending the comprehensive message to the BMS host. According to the invention, through a single physical channel, multiple logic channels are realized, the equipment cost is reduced, and the complexity of comprehensive wiring is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method, a device slave, a construction device management system and a storage medium. Background technique [0002] Building equipment monitoring system is an important part of intelligent building. The building equipment monitoring system can monitor, control and automatically manage various electromechanical equipment such as electricity, air conditioning, lighting, security, fire protection, ventilation, heating, and transportation in the building, making the building a safe, reliable, healthy, comfortable, Warm living environment and efficient working environment, and can guarantee the economical operation of the system and intelligent management. In the prior art, the traditional control scheme of the building equipment monitoring system requires two sets of wiring systems. At the same time, each equipment slave is required to have two physical communi...
