Problems solved by technology

In this case, each indoor unit can only be controlled separately, which is very inconvenient for the building management personnel regardless of the control or monitoring status, and a centralized control system is needed for unified management
[0003] The existing centralized control system uses PC as the control platform, the installation of software is complicated, and the business layer interacts with other Windows applications. When there is a problem with the equipment, it is difficult to troubleshoot and increase maintenance costs.
Moreover, the number of internal units that can be connected and controlled by using the PC as the control platform is small, and the expansion of the communication interface cannot be realized

Abstract

The invention discloses a central air-conditioning centralized control system, which includes a centralized controller, an intelligent electric meter, an outdoor unit and an indoor unit of the central air-conditioning, the centralized controller includes a power supply, an ARM processor and an FPGA, and the power supply is used to supply power to the centralized controller , the ARM processor and FPGA are interconnected through the internal bus, and the FPGA is used for RS485 communication with the outdoor unit and indoor unit of the central air conditioner, to obtain the status information of the outdoor unit and indoor unit of the central air conditioner and cache it in the internal buffer, and then processed by ARM The device is read to the operating system through the bus for processing and storage, and the real-time monitoring and display of the status information of the outdoor unit and indoor unit of the central air conditioner, and the alarm of the indoor and outdoor units are realized through the ARM processor. The ARM processor is used for RS485 communication with the smart meter. For reading smart meter data, the ARM processor is used to centrally or individually control and manage all outdoor units and indoor units in the system according to the preset rules in the schedule management, and realize electricity bill statistics, apportionment and electricity bill alarm.

Description

technical field [0001] The invention relates to the technical field of centralized control of central air conditioners, in particular to a centralized control system of central air conditioners. Background technique [0002] A group of central air conditioners consists of one or two outdoor units (ODUs) and multiple indoor units (IDUs). Generally, there are 1 to 16 IDUs in each group. One control panel can only control one internal unit IDU independently. A floor or a building has an indefinite number of central air conditioners according to the actual situation. In this case, each internal unit can only be controlled separately, which is very inconvenient for the building management personnel regardless of the control or monitoring status, and a centralized control system is required for unified management. [0003] The existing centralized control system uses PC as the control platform, the installation software is complicated, and the business layer interacts with other...
