[specific embodiment]
The utility model is further described below in conjunction with accompanying drawing, and the utility model is still more clearly concerning the people of this professional skill field.
Embodiment:
Referring to accompanying drawing 1, at first, will comprise wireless humiture sensor and wireless IR CO
2The wireless sensor network node of sensor distributes and is installed to the zone that needs intelligent aeration in the room, wireless transceiver in each wireless sensor network node adopts ZigBee wireless network or WiFi wireless network to be wirelessly connected to the input of wireless senser gateway node equipment, thereby the data that the wireless sensor network node collection comes are sent to wireless senser gateway node equipment, and wireless senser gateway node equipment is as the ConnetPort of U.S. DIGI company etc.; The output of wireless senser gateway node equipment then is connected on the variable-frequency ventilation control system by RS485 or Ethernet or power line communication PLC, thereby data are re-send to the variable-frequency ventilation control system, forms a cover whole network control system.
The variable-frequency ventilation control system according in each wireless sensor network node by wireless warm and humid sensor, wireless IR CO
2Each regional information that sensor collects is as temperature, humidity, CO
2Data such as concentration are carried out Energy Saving Control, because for the specific region, CO
2Concentration and personnel amount between clear and definite data relationship is arranged, so native system is by real-time monitoring CO
2Concentration is according to CO in the respective regions
2Concentration in conjunction with the humiture parameter, calculates the optimal ventilation amount, thereby controls the output of fan frequency conversion or the switch degree of air door, realizes the purpose of energy-saving and emission-reduction, intelligently regulates the ventilation of zones of different.
Referring to accompanying drawing 2, described variable-frequency ventilation control system is embedded with process chip and mainly finishes following workflow: (1) beginning; (2) normal mode operation; (3) pick-up transducers data; (4) enter determining program, judge whether to satisfy following condition: enter energy saver mode? the energy-conservation setting value of temperature parameter T=? humidity parameter H=optimum setting value? CO
2Concentration=normal range (NR)? (5), then get back to the normal mode operation in (2) step if above-mentioned condition all satisfies; (6) if there is one not satisfy in the above-mentioned condition, then control fan frequency conversion output or air door switch degree after, return the pick-up transducers data in (3) step again.
