Example Embodiment

[0036] Hereinafter, the computer room air conditioner controller of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is a structural block diagram of a computer room air-conditioning controller of the present invention. Among them, 1 is the main controller, 2 is the data memory, 3 is the display, 4 is the D / A converter, 5 is the Flash program memory, and 6 is the I 2 C drive module, 7 is a digital-to-analog conversion / analog-to-digital converter module, 8 is an I / O expansion module, 9 is an optocoupler for isolating switch input, 11 is a mainboard Can bus controller, and 12 is an I 2 E of C interface 2 PROM.

[0037] The concepts or devices appearing in Fig. 1 are described in detail below.

[0038] Switch input: the switch value here mainly refers to the input value of the protection switch of the compressor, fan, electric heating, etc. When the temperature or pressure exceeds the protection range, the switch will act, and inpu...

Abstract

The invention is to provide a cabinet air-conditioner controller, which comprises a CPU, a memory, a display, an I/O interface, an A/D converter as well as a D/A converter. The invention is characterized in that the CPU and the I/O interface are controlled by a two-line system I<2>C series bus. The cabinet air-conditioner controller is able to overcome the shortcomings in the prior art, realizes the access or removal under the power supply of the system, and is able to conveniently carry out the fault diagnosis and track to a node, therefore, the module needed to be processed or modified is correspondingly upgraded and modified, which decreases the risk cause by the misoperation or inappropriate modification, and enhances the maintainability of the whole system.

Description

Technical field [0001] The present invention relates to a computer room air-conditioning controller, in particular to a computer room air-conditioning controller with higher requirements on temperature and humidity. Background technique [0002] Currently commonly used computer room air-conditioning controllers have the shortcomings of simple control function, not easy to network, low scalability and low information integration, simple interface, relatively expensive, unable to improve control technology, and poor anti-interference ability. Some controllers are only pure hardware control and can only control the air conditioner. There is no multi-air conditioner scheme, the wiring is complicated, the parameter adjustment is inconvenient, and it cannot be customized according to the needs of users. In addition, some controllers start and turn off the air conditioner through power supply and power failure, which greatly shortens the life of the air conditioner. At the same time, th...
