Description

Air-conditioning unit intelligent controller

Technical field

The utility model relates to a kind of building control device, particularly relates to a kind of air-conditioning unit intelligent controller.

Background technology

Rapid growth along with China's economic, expand rapidly in the control market, building of China, yet the control market, building of China is always by Jiang Sen, Siemens, the Zoomlions such as Honeywell monopolize, China is engaged at least 3000 left and right of enterprise that building intelligent is implemented at present, product vendor is 300 left and right nearly also, but can also almost not have with the product of Zoomlion equal quality, in order to break this corner on the market, the development of national brand, need research and development can with Zoomlion race on the same stage high-quality, the low price product, the controller of domestic existing air-conditioning unit is relatively simple at present, can not realize intelligent control, can't contend with international top-brand.

The utility model content

The purpose of this utility model is to provide a kind of new air-conditioning unit intelligent controller.

For achieving the above object, technical solution adopted in the utility model is as follows: the utility model air-conditioning unit intelligent controller comprises central processing unit, sensor sample module, valve control module, speed regulation module of fan, RJ45 module, 485 communication modules, WIFI module, and described central processing unit is electrically connected to sensor sample module, valve control module, speed regulation module of fan, RJ45 module, 485 communication modules, WIFI module respectively.

Compared with prior art, the beneficial effects of the utility model are: the utility model air-conditioning unit intelligent controller can be preset according to the weather forecast of meteorological department the operation curve of air-conditioning unit, and the Real-time Collection external environment condition, revise in time default operation curve according to the external environment condition collected; In pressing the operation curve running, air-conditioning unit intelligent controller, according to the operating condition COMPREHENSIVE CALCULATING of end (room) equipment, is adjusted the operation curve of air-conditioning unit in time, controls the air-conditioning unit and operates under optimal mode, reaches the purpose of saving the energy; Operation curve after adjustment can also be avoided the running overload of air-conditioning unit, and each parts of regulation and control air-conditioning unit are reasonably combined, coordinated operation, the service life of prolongation air unit.

The utility model can be realized the intellectuality control of air-conditioning unit intelligence, in the prerequisite that guarantees comfortableness, is issued to and saves the energy and the purpose in extension device life-span.Realize at home the sports on the same stage with international top-brand on market.Because having considered many national conditions and use habit, given more Chinese culture unit, more be adapted at interior use of building of domestic top grade.

The accompanying drawing explanation

Fig. 1 is structural representation block diagram of the present utility model;

In figure: 1. central processing unit, 2. sensor sample module, 3. valve control module, 4. speed regulation module of fan, 5.RJ45 module, 6.485 communication modules, 7.WIFI module.

The specific embodiment

Referring to Fig. 1, the utility model air-conditioning unit intelligent controller mainly comprises central processing unit 1, sensor sample module 2, valve control module 3, speed regulation module of fan 4, RJ45 module 5,485 communication modules 6 and WIFI module 7, and central processing unit 1 is electrically connected to sensor sample module 2, valve control module 3, speed regulation module of fan 4, RJ45 module 5,485 communication modules 6, WIFI module 7 respectively.

Wherein, central processing unit 1 can adopt the RAM single-chip microcomputer with large storage capacity, the optional STM32F103C8 chip of producing with ST Microelectronics.The pre-stored operation curve that air-conditioning unit under DIFFERENT METEOROLOGICAL CONDITIONS is arranged in the inside of central processing unit 1.The operation curve of air-conditioning unit is (the history run curve of case history) drawn according to the historical data of the relation between Changes in weather and air-conditioning unit operation conditions.

The RP-CY type sensor sample module that sensor sample module 2 can select Hangzhou Runpaq Environmental Technology Co., Ltd. to produce; Valve control module 3 can be selected the YT-T-2 module of Hangzhou Runpaq Environmental Technology Co., Ltd.; The RV-V type stepless time adjustment module that the optional Hangzhou Runpaq Environmental Technology Co., Ltd. of speed regulation module of fan 4 produces; RJ45 module 5 is selected the ethernet communication module of the YT-C-3 of Hangzhou Runpaq Environmental Technology Co., Ltd.; 485 communication modules 6 can be selected the YT-C-1 module of Hangzhou Runpaq Environmental Technology Co., Ltd.; The 5HF-LPB module that WIFI module 7 can select Lierda Science and Technology Co., Ltd. to produce.

During use, sensor sample module 2 in the utility model is connected with each sensor (for measuring temperature, pressure air quantity, air quantity etc.), room external environment condition sensor (as temperature sensor, humidity sensor and the optical sensor) philosophy of air-conditioning unit, valve control module 3 is connected respectively with valve, the fan valve executor of air-conditioning unit water system, speed regulation module of fan 4 is connected with the blower fan of air-conditioning unit, and 485 communication modules 6 are connected with each end-equipment.

During work, the outdoor environment information such as the temperature of the outside, room that central processing unit 1 of the present utility model is obtained by sensor sample module 2 by collection, humidity, illumination.Central processing unit 1 by WIFI module 7 from 3G network (for example telecommunications, movement, UNICOM) know the weather forecast information on the same day.

The operation curve of the air-conditioning unit of the correspondence that central processing unit 1 is stored according to known weather forecast information selection, the outdoor environment information that then foundation gathers is revised the operation curve of air-conditioning unit in real time.Operation curve according to revised air-conditioning unit, central processing unit 1 is controlled the wind speed of the blower fan of air-conditioning unit by speed regulation module of fan 4, control the valve opening of the water system of air-conditioning unit by valve control module 3, control the fan valve executor of air-conditioning unit by control module 3, thus by the wind pushing temperature of prediction and the air quantity terminad equipment air-supply of blowing.Central processing unit 1 carries out communication by 485 communication modules 6 and end-equipment (such as the temperature controller in room, blast volume controller etc.), obtains the needed air-supply air quantity in room and wind pushing temperature and actual air-supply air quantity and the deviation of wind pushing temperature.Central processing unit 1 is adjusted wind pushing temperature and the air-supply air quantity of air-conditioning unit in real time by speed regulation module of fan 4 and valve control module 3 according to above-mentioned deviation, thereby realize the intellectuality control of variable air volume system.By RJ45 module 5, the abnormal demand of end-equipment is fed back to data monitor center by central processing unit 1, confirm by data monitor center whether the abnormal demand of end-equipment needs response again, if need response, by data monitor center, by RJ45 module 5, to central processing unit 1, send response instruction, thereby meet above-mentioned abnormal needs; If do not need response, by data monitor center, to central processing unit 1, sent the instruction that will not respond.In the situation that data monitor center is failed timely feedback information, central processing unit 1 also can judge that whether the demand of end-equipment is reasonable voluntarily, will not respond irrational demand, but can record, and sends to Surveillance center to put on record; Can reply in time the rational demand the utility model of end-equipment, thereby realize that the intellectuality of air-conditioning unit controls.
