Description
Technical field
the present invention relates to a kind of PLC Circuits System and control method, relate in particular in a kind of control circuit that the PLC Programmable Logic Controller is applied to the high-pressure fog cooling system, use the powerful programming Control function of PLC Programmable Logic Controller, the suitable program of demand establishment according to mist cooling, both can reduce manually operated instability, solve manually operated difficult point, can set flexibly again multi-section time controls, solve the automatic control function of mist cooling, simultaneously can also configure temperature sensor, PLC Circuits System and the control method that the greenhouse high-pressure fog is controlled that be used for according to the work of environment temperature auto-control mist cooling.
Background technology
The greenhouse is commonly called as booth, according to the difference of cladding, has respectively film covering, the covering of PC plate, glass to cover.Owing to effectively resisting extreme natural environment, be convenient to control and the climate inside environment of regulating, can help the plantation dealer no longer to rely on physical environment, improve the quantity and quality of product, more and more planted the dealer and accepted.
Glasshouse is with its good transmittancy; good observing effect; whole standardized outward appearance; be suitable for scale, batch production production and management; be convenient to control and the climate inside environment of regulating; can help the plantation dealer more to improve product yield and quality, be accepted by the vast dealer that the large-scale planting demand is arranged.
Because the insulating power in greenhouse is stronger, the high transmittancy of glass also brings the sharp sharp increase of heat to add to the greenhouse, in order to reduce the temperatures involved that daytime, solar radiation was brought to the greenhouse, people find out various ways and go to reduce sunlit impact, as window at outside, greenhouse increase sunshade curtain, inside greenhouse ventilation, fan and pad evaporation humidification, high-pressure spray humidification, earth source heat pump cooling, and the combination utilization of above method etc.
In above-mentioned various cool-down method, outside sunshade only can reduce solar radiation, but can not lower the temperature, and therefore often will be used in combination with the ventilation of windowing, fan and pad evaporation humidification, or be used in combination with high-pressure spray humidification, or be used in combination with the earth source heat pump cooling system.Fan and pad evaporation humidification need configure wet curtain wall, more exhaust blower, corresponding electric control system and energy supply, the earth source heat pump cooling system needs well-digging, be equipped with corresponding source pump, more fan coil and energy supply, required input cost is all larger, energy resource consumption is large, operating cost is high, compares with said two devices, and high-pressure spray humidification generally only needs a high-pressure fog water pump, a small amount of spray pipe, the atomizer of respective numbers just can reach the atomizing cooling-down effect, and is economical and practical, wins high admiration.
Spraying humidification cooling is to utilize the water smoke of fine particle to absorb to take away after airborne heat energy and evaporation that in the greenhouse, the principle of heat plays a role.
The control of greenhouse inner high voltage spraying has multiple solution, has that ball bearing made using is manually controlled, the time relay is controlled, special module is controlled automatically, a computer controlled automatic etc.
The circuit structure that ball bearing made using is manually controlled is simple, cost is minimum, but use operation inconvenience, need the special messenger in control panel place's operation, by people's the operation of feeling, there is uncertainty greatly in the result of high-pressure fog fully, and the effect of high-pressure fog is also bad, therefore the method is eliminated substantially, rarely has the user to adopt.
Time relay control circuit is the improvement to manual control circuit, and the method can solve manually-operated inconvenience with uncertain, have certain control accuracy, but circuit structure is more complicated, and the breakdown maintenance difficulty is large, so the method also seldom adopts.
The appearance of single-chip microcomputer has promoted the function of control module special, panoramic special module is used for the automatic control of greenhouse high-pressure fog, ultimate principle is still time control, control accuracy is greatly improved, but special module function singleness, can not adapt to the on-the-spot demand that changes, price is also higher, and user psychology is more difficult acceptance often.
Computer control system is complex control system, can be by the various types of sensors of configuration, collect the data such as the inside and outside intensity of illumination in greenhouse, temperature, humidity, wind speed, through after the overall treatment of software, the windowing of greenhouse, heavy curtain, humidification, cooling are controlled, be applicable to the environment control accuracy is required high user, need huge fund input.
The PLC Programmable Logic Controller has programming Control function flexibly, cheap cost, and adaptability is extensive, can play a role in all trades and professions, therefore it can be used in the control of high-pressure fog.
Summary of the invention
