Method for determining main and standby controllers and related equipment

Abstract

According to the method for determining the main controller and the standby controller and the related equipment provided by the invention, the controller attribute of the first controller is initialized into the attribute of the standby controller, and the first attribute information of the first controller is sent to the unit communication bus between the first controller and the second controller; and under the condition that second attribute information sent by the second controller is received, determining that a main controller does not exist on the basis of controller attributes in the second attribute information, and under the condition that the MAC address value of the first MAC address information is greater than the MAC address value of second MAC address information in the second attribute information, determining that the main controller does not exist on the basis of the controller attributes in the second attribute information. And determining the first controller as a main controller and the second controller as a standby controller, so that the main controller and the standby controller of the multi-on-line household charging system can be rapidly determined.

Description

technical field [0001] The present application relates to the technical field of multi-connected air conditioners, and in particular to a method for determining an active / standby controller and related equipment. Background technique [0002] The multi-connected household billing system is a device for calculating and apportioning electricity bills for multi-connected air conditioners. At present, the mainstream multi-connected household billing system mostly uses a single controller to collect air-conditioning operation data, electric meter power data collection and billing processing. The energy consumption management of multi-connected units is realized through the monitoring terminal connected with the controller. Because the controller is responsible for data collection and billing apportionment processing, when the controller works abnormally, the entire multi-connected household billing system will be paralyzed. [0003] The current multi-connected household billing ...

Problems solved by technology

In the traditional redundant controller structure system, when the communication between the monitoring terminal and the main controller fails, the system will automatically change the identity of the standby controller to the main controller, but the original identity of the main controller has not been changed to the standby controller. device, so that there are two main controllers in the same unit communication network and the same meter communication network, both controllers will actively collect the data of the unit and the meter, and if the two controllers query the data at the same time on the RS485 bus, it will cause RS485 bus data conflicts, resulting in data acquisition failure
