Problems solved by technology

Even in the operating environment of the real machine, it is limited by the cost of manpower and time, and it is impossible to monitor the memory usage in real time at any time and any place
This limited monitoring of memory usage in a specific environment cannot fully monitor the real operation of the entire multi-connected air conditioning system

Embodiment Construction

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0035] figure 1 It is a system block diagram of the operating environment monitoring system of the multi-connected air-conditioning system in the embodiment of the present invention. Such as figure 1 As shown, the multi-connected air-conditioning system includes multiple indoor units, a main outdoor unit and multiple outdoor sub-units. The indoor unit and the outdoor unit main unit, and the outdoor unit sub-unit and the outdoor unit main unit are connected through a communication bus. All air conditioners have a single-chip microcomputer chip with RAM as the controller. The controllers of the indoor unit and the sub-unit of the outdoor unit are connected to the controller of the outdoor unit host through the communication bus. The operating conditions of the machine and the outdoor sub-unit are d...

Abstract

The invention discloses a method and a device for monitoring the operating environment of a multi-connected air-conditioning system. The method includes: when the controller is initialized, writing predetermined unused identification data into the controller memory; during the real-time operation of the system, calculating the number of the controller memory by detecting the unused identification data in the controller memory Utilization rate: sending the utilization rate of the memory of the controller to the host controller of the multi-connected air-conditioning system, and displaying it through the display device, and prompting that the system is abnormal when the utilization rate of the memory of the controller reaches 100%. The present invention can monitor in real time whether the operating environments of all the indoor units and outdoor units of the whole multi-connected air conditioning system are normal without relying on any simulation tool.

Description

technical field [0001] The invention relates to the control technology of a multi-connected air-conditioning system, in particular to a method and device for monitoring the operating environment of a multi-connected air-conditioning system. Background technique [0002] Multi-connected air-conditioning system is also called multi-connected central air-conditioning system. It is a type of household central air-conditioning. It refers to one or more outdoor units connected to two or more indoor units through pipes. A primary refrigerant air conditioning system in the form of cold heat exchange and direct evaporative heat exchange on the indoor side. Multi-connected air-conditioning systems are increasingly widely used in small and medium-sized buildings and some public buildings. [0003] In a multi-connected air conditioning system, the outdoor unit usually consists of 1 to 4 outdoor units, which can be connected to multiple different indoor units. The number of indoor unit...
