In the Air Conditioning Facilities intelligent cluster control system central air conditioning machine room a variety of equipment such as heat pump main frame, handpiece Water Chilling Units, water pump, motor-driven valve, sensor are arranged, the control system of Air Conditioning Facilities is generally with PLC to serve as the control main body, and computer only shows as auxiliary.Because communications protocol difference between the equipment needs to add gateway hardware, the communication between the realization equipment between equipment and the PLC.PLC calculating and ability to communicate are limited in traditional control system, how efficiently to utilize the communication of computer itself and computing capability to become one of means that improve air-conditioning system monitoring and control accuracy.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of raising control accuracy is provided, and reduces the intelligence controlling device that is applicable to equipment team control in the Air Conditioning Facilities of control device cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of intelligence controlling device that is applicable to equipment team control in the Air Conditioning Facilities, comprise the control host computer, the equipment of band communications protocol, switching value/digital signal equipment and analog signalling, it is characterized in that: also comprise a PLC module, the signal output part of described switching value/digital signal equipment and analog signalling is connected with the signal input part of described PLC module, the signal output part of PLC module is connected to described control host computer, and the device signal output of described band communications protocol directly is connected with described control host computer.
The equipment of described band communications protocol comprises electrical quantity instrument, source pump/single cooler group and frequency converter; Described switching value/digital signal equipment comprises blower fan of cooling tower, water pump and on-off valve; Described analog signalling comprises control valve, temperature sensor, pressure sensor and flow sensor.
Beneficial effect:
1) tradition control main body is PLC, and data-signal collection, data store, data computation is handled and all realized in PLC, and present technique invention control main body is a computer, by the powerful calculating and the storage capacity of computer, can effectively improve system's control accuracy.
2) for the equipment that has communications protocol, it carries one-chip computer module, and its function is consistent with PLC, and communicating by letter between legacy equipment and the PLC needs to adopt hardware gateway come conversion protocols.The same brand of same equipment can be with a gateway, and devices from different manufacturers agreement difference must be selected different gateways.Patent of the present invention adopts programming to realize the software gateway conversion protocols on computers, does not need hardware gateway, reduces the hardware gateway of band communications protocol equipment, does not need PLC, and direct and computer communication reduces investment.
3) for digital quantity signals such as water pump, on-off valves, analog signals such as pressure, temperature, flow need digital-to-analog amount I/O acquisition module.Integrated this module among the PLC.Because these equipment adopt a PLC with the band communications protocol in the conventional method.The PLC of present technique invention usefulness does not need communication protocol module, only with the PLC of digital-to-analog amount I/O acquisition module, has reduced the PLC configuration requirement, reduces investment.
4) use ethernet communication, realize software gateway.The software of independent research has been integrated Modbus RTU, Modbus ASCII, Modbus TCP, Profibus DP, MPI, communications protocol such as USS, TCP/IP
5) owing to having adopted computer to be the control main body, can be by calculating, the storage capacity of computer, software section has adopted the three-dimensional animation demonstration, MAYA2009, three-dimensional animation softwares such as 3DMAX, SQLserve2000 database, VC#2008 sets up module, the picture image.
