Log-on data acquisition processing system after first preset time detects the air themperature in batch meter in real time.
Wherein, the first preset time is 10 minutes~30 minutes.
Specifically, when detecting generally with the first default water temperature refrigerating operaton, the first default water temperature is generally refrigeration water tank
12 °C~20 °C, but since the refrigeration water tank water temperature of Various Seasonal is different, for example, summer, refrigeration water tank just starts water temperature
At 25 ° or more, in winter, the incipient water temperature of refrigeration water tank is at 10 °C hereinafter, therefore, refrigeration water tank is preferably first run before detection
At the first time, water temperature is made to be near the first default water temperature.
Data acquisition processing system respectively with the first temperature sensor, second temperature sensor, third temperature sensor,
Four temperature sensors, flow sensor connection, for acquiring the air themperature of the air themperature of external environment case, batch meter, heat is handed over
The water flow of the inlet water temperature of parallel operation, the exit water temperature of heat exchanger and water pump, after log-on data acquisition processing system, the second temperature

S4, start artificial light source, first heating refrigeration system, fan, third heating refrigeration system, water pump, refrigeration water tank,
Secondary heater, control device and data acquisition processing system, wherein, refrigeration water tank is with the first default water temperature refrigerating operaton, water
Pump is run with the first default water flow.
Specifically, in order to effectively improve detection speed, it should judge whether the air themperature in batch meter is in before detection
First preset temperature section, the upper limit in the first preset temperature section for first preset temperature and the first threshold temperature it
With the difference of the lower limit in, the first preset temperature section for first preset temperature and the first threshold temperature, described first in advance
If temperature is preferably 25.5 °C~26.5 °C, first threshold temperature is preferably 1 °C~2 °C.
Detection start when by the air themperature in batch meter respectively with the first preset temperature section upper limit, the first preset temperature
Interval limit is compared, and the operation of the water pump or secondary heater is controlled according to comparison result.
If the air themperature in batch meter is more than the upper limit in the first preset temperature section, water pump is controlled to open and is added with second
Hot device closes to reduce the air themperature in batch meter；It should be noted that after water pump is opened, judge to measure every preset time
Whether the air themperature in case is more than the upper limit in the first preset temperature section, if so, water pump continues to open operation, if it is not, then
It switches off the pump immediately.
If air themperature in batch meter is less than the lower limit in the first preset temperature section, control secondary heater open and
Water pump closes to increase the air themperature in batch meter；It should be noted that after secondary heater is opened, sentence every preset time
Whether the air themperature in disconnected batch meter is less than the lower limit in the first preset temperature section, if so, secondary heater continues to open
Operation, if it is not, then closing secondary heater immediately.
If the air themperature in batch meter is in the first preset temperature section, secondary heater and water pump is controlled not to beat
It opens.
When the air themperature in batch meter is in the first preset temperature section, start artificial light source, the first heating refrigeration
System, fan, third heating refrigeration system, water pump, refrigeration water tank, secondary heater, control device and data acquisition process system
System, wherein, refrigeration water tank is run with the first default water temperature refrigerating operaton, water pump with the first default water flow.
