Description

Discrete air-conditioning centralized control system device

Technical field the utility model relates to a kind of unified management control system, be applicable to middle-size and small-size public place, by the RS485 bus switch, temperature value, the strong and weak wind of a plurality of room air conditioners are unified control and management, and can reach energy-conservation purpose according to whether the someone realizes the switch of air-conditioning is controlled in the room.

The background technology air-conditioning brings a lot of convenience to the modern, and existing central air-conditioning is with two kinds in discrete air-conditioning.Adopt central air-conditioning at large-scale public place, convenient because its advantage is control, be convenient to unified management, shortcoming then is the price comparison costliness, safeguards loaded down with trivial details.Then discrete air-conditionings of installing in middle-size and small-size place more, its advantage is low price, but has brought very big inconvenience for administrative staff's unified management, more is the waste that causes the energy, this is the deficiency of prior art products.

The summary of the invention the purpose of this utility model is to solve the centralized Control and and the computer remote monitoring problem of multiple spot discrete air-conditioning.

For achieving the above object, the utility model adopts following technical scheme: discrete air-conditioning centralized control system device, it comprises upper computer module, trunk module and slave computer module, they are connected to each other successively, in upper computer module, establish PC and RS232/485 converter, in the slave computer module, be provided with and the corresponding single-chip microcomputer of air-conditioning equipment, control system is by information acquisition circuit, single chip machine controlling circuit, the RS232/485 built-up circuit, control software is formed, and described signal acquisition circuit mainly is made up of DS18B20 temperature sensor testing circuit and BISS0001 infrared circuit; Single chip circuit is made up of control circuit, display circuit, warning circuit, and realization is communicated by letter overtemperature alarm with upper computer module; The RS232/485 built-up circuit that is used for the high-low level conversion mainly is made up of with a series of discrete component MAX232, MAX485, and the computer high-low level is ± 12V that the single-chip microcomputer high-low level is ± 5V; The control software interface uses VC++6.0, uses communication control MSCOM, during operation by serial ports of computers or use USB to change serial ports and carry out and the communicating by letter of slave computer module.Information acquisition circuit is gathered the temperature value in the room in real time and is had or not personal information by temperature sensor DS18B20 and infrared sensor BISS0001 and treatment circuit thereof; Single chip machine controlling circuit uses the STC89c52 single-chip microcomputer that air-conditioning is controlled, and adopts the circuit that embeds in the air-conditioning hardware or by infrared air-conditioning is carried out control mode, uses buzzer alarm circuit buzzer when overtemperature to report to the police; Adopt the RS485 bus to carry out the one-to-many serial communication and reach long transmission distance, multinode, jamming-proof purpose; Control software adopts by VC++ independent development control system, realize the state in each room of remote monitoring, close the air-conditioning in the corresponding room when having no talent between clock room, to reach energy-conservation purpose above 20 minutes, when spending above 40, room temperature reports to the police, so as to avoid an accident accident.

The utility model beneficial effect is; Simple in structure, cost is low, can reliablely and stablely detect and control the major parameter of a plurality of discrete air-conditionings by computer, reach to make things convenient for unified management and purpose of energy saving.
