Embodiment

In conjunction with the accompanying drawings embodiment is described:

With reference to figure 1: temperature, 1 HPR-MQ-M52R humidity sensor of 2 DS18B20 temperature sensors of the actual employing of humidity collecting unit come simultaneously indoor and outdoor temperature and outside humidity are gathered, difference, outside humidity by indoor and outdoor temperature are used as judging one of condition whether ventilation equipment can start, thereby reach the effective purpose of energy saving of effective cooling.Temperature, humidity collecting unit directly synchronously for the data logic control element provides digital signal, make logic control element stable, and subsequent screen shows detection data and control control temperature equipment.

The control temperature equipment comprises air-conditioning, ventilation unit, the data logic control element can be according to the parameter signal of outside temperature, humidity collecting unit, the output of air-conditioning state acquisition unit, carry out operational analysis, control starts, closes air-conditioning or ventilation unit (air-intake device, go out wind apparatus).When satisfying the temperature control requirement equally, the less ventilation unit of preferential starting power is to reach energy-conservation purpose.Ventilation unit divides high wind, weak wind gear, and the data logic control element carries out the switch blower fan according to temperature, humidity collecting unit parameter.Promptly can save energy, ventilation unit inside is taken turns to operate, improve service life of equipment.Ventilation unit is equipped with the automatic dustproof device, and the automatic dustproof device is made up of self closing door, filter screen dedusting rolling mechanism, by the data logic control element to the memory that adds up of the working time of ventilation unit.Working time reaches when setting accumulated value, starts filter screen dedusting rolling mechanism automatically.The dedusting time is artificially set at machine shell panel flexibly according to local air quality.

In air-conditioning control, take the mode of monitoring in real time, to guarantee that air-conditioning virtual condition and air-conditioning need state to be consistent under improper situation.The ventilation equipment that adopt are blower fan groups of the big air quantity of low-power consumption, turnover wind, can adopt 1 group, 2 groups ventilation equipment according to regional situation difference, and according to the cooling demand difference judge the blower fan number of being opened voluntarily by CPU, starting of air conditioner is by the air-conditioning state detection unit, the data logic control element is grasped the air-conditioning current state earlier, export respective drive signal again, reliable to guarantee control.The measure of ventilation unit automatic dustproof is that the data logic control element adds up the memory ventilation output services time automatically, reaches behind the artificial setting-up time to start automatically.Automatically the time length of dedusting artificially can be set flexibly according to local air quality.The power monitoring unit is when preventing that ac power supply system from going wrong, and the assurance communication facilities is kept the communication sending and receiving for a long time and received function, and control module withdraws from the set unit of function of control automatically.Analog quantity (switching value) input block, analog quantity (switching value) output unit can provide the monitoring and the warning function of temperature, gate inhibition, fire-fighting, immersion, power failure for the base station, by alarm unit, external communications units in time and Surveillance center establish a communications link.It is dynamic to allow basestation operator in time understand base station (machine room) environment.For avoiding external factor to cause interference to control module, every passage has all adopted optocoupler to do quarantine measures.
