In order to ensure normal, the reliably working of high-tension electricity equipment such as switch cubicle, mid-cabinet, has a higher requirement to its inside is anti-condensation.At present in order to prevent the device interior condensation, 1 or 2 well heaters can be set, produce heat when utilizing its work, improve temperature, prevent the generation of condensation phenomenon, because the well heater power consumption is big, consideration in line with energy savings, well heater is preferably only worked when needed, and to the control of well heater, multiple mode is arranged.Mode commonly used is to adopt resistive type condensation sheet as sensor, utilize the parametric line flex point of this condensation sheet, realize the purpose that control heater starts, though this mode circuit is simple, but precision is very poor, dewfall usually appears and controller does not start the situation of well heater yet, and start to control a little and can not change setting, because China region is wide, weather is different, each regional temperature, humidity difference are very big, therefore control are required also to be not quite similar, and this kind controller also can't reach request for utilization preferably.
Another temperature and humidity controller, be with traditional hygristor and humicap as sensor, yet its precision is not high, the life-span is very low, especially under hyperbaric environment, analog quantity is easy to be interfered in transmission course, causes measuring accuracy to reduce.
In addition, traditional controller only when heater, just can detect the duty of well heater, and if well heater breaks down, can't heat in that the needs heating state is next, influences the normal operation of power equipment.
Because above-mentioned analysis, the design people studies improvement at the structure of the temperature and humidity controller of present anti-condensation effect, and this case produces thus.
The utility model content
Fundamental purpose of the present utility model is to provide a kind of temperature and humidity controller, its measuring accuracy height, and the functional reliability height, anti-condensation effect is good.
Secondary objective of the present utility model is to provide a kind of temperature and humidity controller, and its objective interface makes things convenient for the staff to check.
A purpose more of the present utility model is to provide a kind of temperature and humidity controller, and it is applied widely.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of temperature and humidity controller, be arranged in the high-tension apparatus, comprise MCU, power module, Temperature Humidity Sensor module, at least one well heater and at least one heater control module, wherein, heater control module is identical with the number of well heater, and corresponding one by one; The Temperature Humidity Sensor module comprises the digital hygro sensor of temperature sensor and humidity sensor one, and its output terminal is connected with the input end of MCU; The output terminal of MCU connects all heater control module, and controls the keying of each well heater by heater control module.
Above-mentioned each well heater all is connected with the well heater selftest module gathering its working current and send into MCU.
Above-mentioned MCU is connected with alarm module.
Above-mentioned MCU is connected with the LCD MODULE that can show Current Temperatures, humidity value, configuration information, abort situation information.
Above-mentioned MCU is connected with the keyboard load module.
The hot output terminal that adds of above-mentioned well heater is a normally closed contact.
After adopting such scheme, the utlity model has following improvement:
(1) because relative humidity is the function of temperature, the Temperature Humidity Sensor module adopts digital hygro sensor, can effectively guarantee the response speed and the precision of measured temperature and humidity, and the digital hygro sensor module is that temperature sensor and humidity sensor are set together, guarantee that the temperature and humidity value of gathering is in same collection point, measurement result is accurate;
(2) MCU stores the condensation curve, and according to the critical setting valve of this curve setting humiture, and when measured value surpasses setting valve heater, like this, before taking place, condensation just destroys its generation condition, compare the control method that lags behind in the existing structure, leading control mode reliability provided by the utility model is higher, anti-condensation better effects if;
(3) the well heater selftest module is set, when working, well heater detects its duty in real time, the enforced opening well heater carries out self check at set intervals simultaneously, can effectively avoid only when well heater needs work, just finding fault like this, influence operate as normal, and when well heater broke down, the very first time was sent alerting signal, guaranteed the operate as normal of controller;
(4) the utility model also can connect LCD MODULE, shows current temperature, humidity value in real time, for staff's reference, objective interface;
(5) the utility model also can connect the keyboard load module, can conveniently import the setting valve of MCU stored, regulates setting valve according to the working environment of reality, has realized all can using under different environment, enlarges the scope of application.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Embodiment
With reference to shown in Figure 1, the utility model provides a kind of temperature and humidity controller that is arranged in the high-tension electricity equipment such as switch cubicle, it comprises MCU (Microcontroller Unit, microcontroller) 1, power module 2, Temperature Humidity Sensor module 3, at least one well heater 4 and at least one heater control module 5.
Power module 2 is connected with MCU1, for it provides operating voltage, and provides operating voltage by it for all the other components and parts.
Temperature Humidity Sensor module 3 comprises the digital hygro sensor of temperature sensor and humidity sensor one, and the two is set together, by adopting digital transducer, can guarantee to measure the response speed and the precision of temperature and humidity, strong interference immunity, and the two is an one, guarantees that temperature and humidity are in same collection point, improve measuring accuracy; The output terminal of Temperature Humidity Sensor module 3 is connected with the I/O interface of MCU1, temperature and the humidity value gathered are sent to MCU1, in order to ensure operate as normal, present embodiment also connects MCU1 one alarm module 6, and set when MCU1 and 3 appearance of Temperature Humidity Sensor module continuous 3 times can't normal communication the time, judge Temperature Humidity Sensor module 3 status faults, control warning module 6 is sent warning message, and the prompting staff notes.
