Abstract

An air conditioner network central management device comprises air conditioners, a communication network cable and a computer and is characterized in that a network controller for controlling the work of the air conditioners is respectively and fixedly installed beside each air conditioner. A USB serial port of the computer switches through USB/485 and is connected with an interface network of a communication interface RS485 of the network controller. The device has the beneficial effects: the central management device realizes the central management over air conditioners through the network and effectively eliminates the phenomenon that the air conditioners are not turned off after use; the running temperature of the air conditioners is uniformly set by a manager so as to guarantee the implementation of the energy saving and temperature limiting policy; and through the in-situ temperature sent by the network controller, whether the air conditioners work normally can be judged. Therefore, the manager can control all the air conditioners just by sitting in front of the computer but not to walk out of the office.

Description

Air-conditioning network centralized management device

Technical field

The utility model relates to the control system of air-conditioning, and especially a kind of network of multi type air conditioner is concentrated the administration of energy conservation control device.

Background technology

Wall-hanging, the cabinet type split-type air conditioner One's name is legion of school, office, public place is installed and is disperseed at present.Except operating at the scene the control, there is not a kind of equipment that can manage control to air-conditioning concentratedly in the market with simple remote controller.Often temperature is freely set, and the warm energy saving policy of country limit can not effective execution; Enter and turn on the aircondition conveniently, go away and usually forget the pass, cause indoor unmanned air-conditioning idle running, electric energy wastes phenomenon.Do not manage control concentratedly, the administration of energy conservation difficulty is very big.

The utility model content

The purpose of this utility model provides a kind of air-conditioning network centralized management device, by the centralized management control device of network realization to air-conditioning.

For achieving the above object, the technical scheme that adopts is: a kind of air-conditioning network centralized management device, comprise air-conditioning, communication netting twine and computer, it is characterized in that: every other network controller that is installed with the control operation of air conditioner respectively of described air-conditioning, the USB serial ports of described computer is changed through USB/485, is connected with the communication interface RS485 interface network of described network controller.

Microprocessor partly is electrically connected with communication interface, real-time clock module, infrared emission circuit, led state demonstration, action button, temperature survey respectively in the described network controller.

Described microprocessor is the C8051F330 chip.

Described real-time clock module is the ISL1208 chip.

Described network controller can adopt three kinds of mode of operations: or by predefined clock switch and temperature parameter in the microprocessor, adopt the operation of automatic control mode control air-conditioning, or control by pressing action button execute-in-place mode, or accept the instruction of computer installation, remote control mode control operation of air conditioner by communication network.

Good effect of the present utility model is: air-conditioning network centralized management device, by the centralized management of network realization to air-conditioning, air-conditioning unified management numerous, that disperse is got up, automatically carry out the operation of open and close air-conditioning according to timetable separately, having eliminated air-conditioning effectively has the people to open, and forgets the phenomenon of pass.The operation design temperature of air-conditioning is provided with by the keeper is unified, can guarantee implementing of energy-saving temperature-limiting policy; On the computer of centralized management, can count the running time of every air-conditioning, as using the foundation that to examine or to charge; From the scene temperature of returning by network controller, can judge whether air-conditioning open-minded, whether normally move, the keeper need not walk out office, only need be sitting in just can control before the computer overall.

The specific embodiment

A kind of formation of air-conditioning network centralized management device, as seen from Figure 1, comprise air-conditioning 1, communication netting twine 3 andcomputer 4, it is characterized in that: every described air-conditioning 1other network controller 2 that is installed with respectively, Fig. 2 is the network control principle schematic, the USB serial ports that illustrates describedcomputer 4 is through the USB/RS485 interface conversion, and (diagram network controller 2 quantity are 1,2 with each describednetwork controller 2 ... N) the RS485 interface network ofcommunication interface 5 connect.Computer 4 can be provided with switching on and shutting down time and the various parameter that stores in themicroprocessor 10 by communication netting twine 3, receives the parameters of returning fromnetwork controller 2 such as scene temperature simultaneously.Network controller 2 is accepted the instruction thatcomputer 4 is provided with by communication netting twine 3, the operation of remote control mode control air-conditioning 1.

Communication modes betweencomputer 4 and thenetwork controller 2 except above-mentioned cable network connects, also can adopt cordless communication network to connect.

Fig. 3 is the network controller calcspar, Fig. 4 is the concrete line map of Fig. 3, andmicroprocessor 10 is electrically connected withcommunication interface 5, real-time clock module 6, infrared emission circuit 7, ledstate demonstration 8, action button 9,temperature survey 11 respectively in the network controller described in the figure 2.Describedmicroprocessor 10 is the C8051F330 chip.Described real-time clock module 6 is the ISL1208 chip.

When automatic control mode,microprocessor 10 is constantly checked from the time data that real-time clock module 6 reads in the switching on and shutting down of current real-time time and storage, judge whether to carry out start or shutdown command, the order of start or shutdown is sent control routine by infrared emission circuit 3, air-conditioning 1 receives and moves by the control routine command switch, it is temporary that the variation of on-the-spot room temperature is then sent intomicroprocessor 10 bytemperature survey part 11, during poll, can read this house temperature throughcommunication interface 5 by the RS485 interface, thereby realize monitoring scene temperature.

The execute-in-place pattern is mainly used in on-the-spot Installation and Debugging, can manually select opening or closing, freeze or heat etc. of air-conditioning at the scene by action button 9.

The switching of 10 3 kinds of mode of operations of microprocessor is realized by the mode that the keeper issues an order on computers.Under automatic control and remote control mode, the push-botton operation of action button 9 lost efficacy.

The start that sets in advance in themicroprocessor 10, shutdown " timetable " have two: 1. time-of-week table: start in seven days from the Monday to the Sunday, unused time table, can arrange every day carry out switching on and shutting down at most, the start parameter has refrigerating/heating, design temperature, air quantity etc. four time periods; 2. unused time holiday is shown in 1 year.These two timetables all can be provided with oncomputer 4, are transferred to thenetwork controller 2 of appointment by grid line.

The timetable of the utility model open and close air-conditioning, start design temperature all are provided with by the keeper is unified, have guaranteed implementing of energy-saving temperature-limiting (refrigeration in summer is not lower than 26 ℃) policy, and having eliminated air-conditioning effectively has the people to open, forget the phenomenon of pass.By the scene temperature thatnetwork controller 2 returns, can judge whether air-conditioning 1 operation is normal, for administration of energy conservation provides a kind of economy, instrument efficiently.

The utilitymodel network controller 2 is to be fixedly installed on air-conditioning 1 side, also can design in air-conditioning 1, can satisfy the needs of administration of energy conservation better.
