Described radon chamber constant temperature and humidity automaton, concrete implementation step is as follows.
1. radon chamber controls: when system starts, solenoid valve in radon need storage unit and pneumatic pump are opened, the radon of radon need is taken out, then the solenoid valve of circulating line and pneumatic pump are opened, radon in radon need storage unit and radon chamber are circulated, calculate according to desired concn and get the gas time, after reaching computing time, close solenoid valve and the pneumatic pump of circulating line, now open the power fan in radon chamber, radon in radon chamber is mixed, radon consistence after a period of time in radon chamber can tend to balance and stablize, but due to the decay characteristic of radioactivity self, radon natural decay is there will be after a period of time, then the solenoid valve on circulating line and pneumatic pump is opened, the gas time is got according to the radon gas declined in Variable Control radon need storage unit that Decay Law calculates, then power fan mixing again, after a period of time, concentration will reach the concentration of initial setting, the time maintained is needed according to this concentration, control the cycle index of this process, cooperation by pilot lamp on flow process indication panel while carrying out radon chamber control indicates ongoing process, handled easily person can accurately understand the process run.
2. the detection of radon consistence and display: place the emanometer as standard in radon chamber, for the radon consistence in Real-Time Monitoring radon chamber, and by digital independent transport module by the digital independent of this emanometer and to controller transmission, the data received are carried out process and are outputted on display screen and PC by controller.
3. the monitoring in radon chamber: be the situation in Real-Time Monitoring radon chamber, comprise reference instrument, by calibrating instrument, power fan etc.; But consider the sealing of radon chamber and the restriction of manufacture craft, adopt the situation of camera Real-Time Monitoring radon chamber environment, by DVR decoding, the situation in radon chamber is shown in real time on PC.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
