Description
Technical field
The invention belongs to hospital clean technical field, more particularly to a kind of operating room four seasons temperature and humidity control system.
Background technology
Hospital operating room is very high to air quality requirement, and humiture also has the control requirement of corresponding specification.Due to operation
The equipment such as indoor shadowless lamp, general lighting lamp can produce influence to temperature and humidity；It is empty when indoor humidity is more than 60%
The speed of bacterial reproduction will greatly speed up in gas, for the patient in purification region there may be fatal harm, so wet
Degree control is also extremely important.This requires that the air-conditioning system in operating room can gather accurate indoor temperature and humidity and make corresponding
Regulation.Traditional Temperature and Humidity Control only sets sensor in air outlet, and temperature humidity computing is referenced as fixing setting
Value, it is impossible to which the humiture difference according to each season makes corresponding adjustment, warm and humid angle value and the actual humiture in interior of collection are deposited
In larger error, cause control inaccurate, and needs 25 minutes or longer time could be steady temperature and humidity control
It is fixed.With the development of microelectric technique and computer technology, the temperature and humidity control system of large time delay is progressively by high accuracy, sound
Speed is answered to be replaced with intellectualizing system soon.
The content of the invention
It is an object of the invention to：Overcome prior art not enough, there is provided a kind of operating room four seasons of energy fast and stable are warm and humid
Degree control system.
To achieve the above object, the technical scheme is that：
A kind of operating room four seasons temperature and humidity control system, including pattern setting, multipoint acquisition, fortune
Calculate and control is performed.System has four kinds of patterns of spring, summer, autumn and winter, and each pattern has temperature and humidity setting value, there is 8 temperature
Degree collection point and 8 humidity collection points, be respectively arranged in exhaust outlet, return air inlet, air outlet and operating room other mainly
Side, by temperature sensors of high precision and humidity sensor Real-time Collection temperature and humidity data, feeding back to controller carries out computing.
Its dehumidifying threshold value, humidification threshold value, heating threshold value, refrigeration threshold value etc. use segmented pid algorithm, set certain upper and lower bound
Value, controller controls actuator to act under four kinds of pattern rules of spring, summer, autumn and winter, carries out the real-time regulation of temperature and humidity.Humidity
Preferential regulation and control；Whole system regulation and control stabilization time is no more than 15 minutes.
A kind of operating room four seasons temperature and humidity control system, its workflow is：
（1）The signal for gathering each sensor feeds back to controller；
（2）Controller does computing, takes the Temperature Humidity Sensor average value of multiple positions in operating room as the temperature value of operating room
Or humidity value；
（3）When temperature value or humidity value are less than mode settings, controller starts heating or humidification action logic, and actuator is held
Capable this action；When temperature value or humidity value are more than the initial value that pattern sets, controller starts refrigeration or dehumidifying action logic,
Actuator performs this action.
Further, the temperature data for being arrived according to 8 temperature acquisition point Real-time Collections, with reference to current season pattern, passes through
Controller does computing and averages, and obtains accurate indoor temperature, then is contrasted with setting value, performs corresponding heating and freezes
Instruction；According to the humidity data that 8 humidity collection point Real-time Collections are arrived, computing is done by controller with reference to current season pattern and is taken
Average value, obtains accurate indoor humidity, then is contrasted with setting value, performs corresponding humidification and dehumidifying instruction.Specifically, first
First gather the signal of each sensor, do computing and average the temperature value and humidity value obtained in operating room, if temperature and
Humidity is less than the initial value for initially setting up, then start heating and humidification apparatus, if temperature and humidity is first more than what is initially set up
Initial value, then start refrigerated dehumidification equipment.
As a result of such scheme, the beneficial effects of the present invention are：
（1）Ember Days spring, summer, autumn and winter selection mode possesses powerful time control function, and timing is accurate convenient.
（2）Multi-point collecting temperature and humidity value, collection information are more accurate, are calculated temperature and humidity data more smart
Really, control time is shortened, the operating efficiency and stability of control system is drastically increased.
