Specifically, this online controller comprises the air-valve testing circuit, and the signal output part of air-valve connects the detection input port of this air-valve testing circuit.
If terminal air-valve is opened, the air-valve testing circuit will be exported the alternating voltage control air-valve of 220V and open, if close then cut off control power supply output, online controller is by the output voltage of air-valve testing circuit, can obtain the information whether air outlet is opened, transfer data to generator set controller then, unit is opened ratio (having opened air outlet quantity divided by the total air outlet quantity) air quantity of control inner blower and the ability output of compressor according to the end of feedback.If close unit when terminal all air-valves all cut out.By online controller, the open and-shut mode and the air-conditioning unit of airduct air outlet are connected, make it become an organic entity rather than unit independently, the air-conditioning unit can obtain the unlatching quantitative proportion of terminal air outlet in real time and be transferred to generator set controller by online controller, and generator set controller can be regulated air quantity, compressor capacity output and the unit start and stop etc. of inner blower automatically according to the information that online controller provides.
This online controller comprises the RS485 communicating circuit, connects the air-conditioning unit by the RS485 bus, transfers data to the air-conditioning unit by the RS485 bus communication.This RS485 communicating circuit comprises serial communication chip and the MCU that is connected.This serial communication chip is connected with receiving terminal/transmitting terminal of MCU.
Also have a toggle switch on the concurrent connections controller, be used for setting
Total air outlet quantity of engineering actual installation.
The contrast prior art the utlity model has following advantage:
The utility model air-conditioner control system can be regulated air quantity, compressor power output, the start and stop of control unit in real time automatically, and is energy-conservation, noise is low, and improved the unit operation reliability greatly.

Fig. 2 is the schematic diagram of the air-valve testing circuit of the utility model air-conditioner control system;
Fig. 3 is the schematic diagram of the RS485 communicating circuit of the utility model air-conditioner control system.
[specific embodiment]
See also Fig. 1, air-conditioner control system of the present utility model comprises the air-valve of the airduct air outlet that is installed in unit, the generator set controller and the online controller of air-conditioning unit, the output of this air-valve is connected to the air-valve testing circuit port of online controller, and online controller links to each other with generator set controller.This online controller comprises the RS485 communicating circuit, connects the air-conditioning unit by the RS485 bus, transfers data to the air-conditioning unit by the RS485 bus communication.Also have a toggle switch on the concurrent connections controller, can set
Total air outlet quantity of engineering actual installation.
See also Fig. 2, the testing circuit of air-valve comprises optocoupler (PHOTOCOUPLE), and the parallel resistance 60K ohm that is attached thereto.When the air-valve of air outlet when opening, air-valve detects connector Valve1 end input voltage 220V, parallel resistance 60K ohm, electric current 220/60=3.7mA, the optocoupler conducting, the IN1 that is connected with single-chip microcomputer IO mouth holds output low level; VALVE1 was input as 0V when air-valve cut out, and the electric current by the light lotus root is 0, the not conducting of light lotus root, and IN1 exports high level.Online controller judges that according to the level signal of this testing circuit air-valve opens and closes state, and being transferred to generator set controller, unit is opened ratio (having opened the ratio of air outlet quantity and total air outlet quantity) air quantity of control inner blower and the ability output of compressor according to the end of feedback.If close unit when terminal all air-valves all cut out.
