Specific embodiment one
The room temperature control algolithm: simple fuzzy controller and PID fuzzy controller are combined, constitute a kind of bimodal multiplex control system, the coordination of two kinds of controllers is then finished by the intelligent coordinated of upper level.Be E with actual temperature and design temperature difference, the slope EC of last cycle variations in temperature.The fringe of E can be divided into: negative big (5 degree are following), negative in (5 degree are to-1 degree), negative little (1 degree is to 0 degree), just little (0 degree is to+2 degree), honest (more than 2 degree).Because actual temperature is a lot of if exceed design temperature, this control system there is not effective method to reduce by temperature, so need not honest this state.
Illustrate: when room temperature is littler 0.9 ℃ than design temperature, last cycle temperature variation curve is 0.8 o'clock, and the aperture in next cycle just is half of last cycle aperture.
The aperture in the last cycle of value representation of U in the following table according to the room temperature control algolithm, is considered especially and tried not to allow actual temperature exceed setting value, and is as shown in the table:
The hydraulic equilibrium algorithm: each on-off controller has 6 unique bit address, with two zero-times as calculating parameter computing controller control cycle behind the address.
Formula is as follows:
min=int（ADDR*0.5）；
sec=[ADDR*0.5-int（ADDR*0.5）]*60；
Min: be control cycle zero-time branch;
Sec: be control cycle zero-time second.
Be unit like this with 30s, 60 groups of different constant time ranges just can be arranged in half an hour, calculate with 240 families, every building, same time valve opening time only is 4.
Specific embodiment two
In the product development process operational reliability of equipment such as on-off controller 3, room temperature remote controller 4 is tested, wherein room temperature remote controller 4 adopts built-in lithium battery ER14505, voltage: 3.6V, 1900mAh.According to maximum three times of room temperature remote controller 4 and on-off controller 3 per communications half an hour, each duration 1s, each communication electric current 30mA calculates, then the battery pot life is 1900/(365 * 24 * 2 * 30 * 3 * 1/3600)=4.3 years.Considered the battery-conserving switch in non-heating season during because of product design, so by the north 150 days seasons of heating, battery can use 9 heating seasons.Through square meter operation surplus two heating seasons, 80,000, up to now, each equipment dependability has obtained the check of actual engineering, and is respond well., finally draw in room temperature and the valve transient state data record of opening dutycycle for three days on end in 27～29 December by the user: each user's room temperature control is substantially in design temperature ± 0.5 ℃, and room temperature control is respond well.Open change in duty cycle from the valve transient state and can see obviously that dutycycle reduces the room temperature uphill process, room temperature descends, and dutycycle increases, and the trend of moving is in advance arranged, thereby effectively controls room temperature.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
