Embodiment
As shown in figure 1, radon chamber periphery room radon consistence continuous detecting system by PC host computers, Zigbee telegons,
Zigbee terminal devices, RAD7 emanometers composition.The wireless sensor network for being made up of RAD7 emanometers and Zigbee serial ports
Terminal in network is not standby connected, and the data of emanometer are first transferred to terminal device, then are transferred to association by Zigbee wireless modules
Device equipment is adjusted, coordinator unit passes through host computer of the Serial Port Transmission to Pc again；The infrared sensor on terminal device also will simultaneously
A mark is sent when testing person enters and leaves radon chamber and arrive host computer, host computer just got testing person enter with
The time of radon chamber is left, the radon consistence data after parsing and time data are deposited personal data storehouse by host computer, and can passes through afterwards
The a large amount of radon consistence data and operating time data that are obtained in database further assess the effective dose of testing person.
Radon is to be widely present in radgas colourless, tasteless in environment, is the production of the radioactive elements such as uranium, radium decay
Thing.Radon in air and its daughter can be inhaled in human body, declined by the radon in suction human body and its daughter in respiratory by people
The interior irradiation based on respiratory apparatus can be caused during change, cause organ damage.Place oneself in the midst of finite concentration radon and its daughter
In air, " the α potential exposure " of " radiant exposure " and radon daughter of the exposure including radon suffered by human body or " cruelly
Dew amount ".The neat Ij amounts research of radon shows that it is primarily not to be declined from radon α to inhale people's body containing radon gas in the dose of radiation that respiratory tract is formed
Become, but the short life daughter from radon218Po (RaA) and214HPo (RaC) alpha-decay.Suction radon daughter can cause to people
The radiation exposure of body, commonly referred to as expose.When the exposure to radon daughter carries out dose evaluation, it is necessary to exposure radon daughter
Amount is converted into effective dose.Radon and its daughter are recommended using UNSCEAR1993 annual reports year effective dose estimation caused by the public
Radon dose conversion method, calculation formula is：Year effective dose=balance equivalent concentration × year irradiation time × dosage conversion system
Number；In formula：Dose conversion coefficient is reported as 9 × 10 according to UNSCEAR 2000-9(Sv/Bq.h.m-3) ；Balance equivalent concentration
For the product of indoor radon concentration and balance factor, indoor balance factor is 0.4；Year irradiation time be 365 × 24h × residence because
Son, occupancy factor 0.8.In the present system, measurement is the radon consistence on particular surroundings radon chamber periphery, and is used in system
Infrared sensor accurately to calculate the working time of testing person, so year irradiation time here takes accurate the one of measurement
Working time in year.
As shown in Fig. 2 the Zigbee wireless sensor network in system is using CC2530 chips, RAD7 emanometer energy
Enough it is connected by R232 serial ports with Zigbee terminal devices, and infrared sensor can be set with relay by I/O mouths with terminal
It is standby to be connected.
The application program of slave computer and upper computer software has the API of corresponding operating serial ports, is defined between both
The data format of one serial communication, it is possible to realize the communication of host computer and slave computer, the system defines 32 bytes
Data format, beginning and end is respectively the starting and ending mark of a byte, and command header distinguishes different set with 3 bytes
Standby read-write operation, represent that physical address and network address are the physical address because Zigbee with 8 bytes and 2 bytes respectively
It is 8 bytes and 2 bytes with network address, the byte of data division 16 is used for storing the data to be transmitted, and the check bit of 1 byte is used
Whether correct transmitted in verification data.
As shown in figure 3, slave computer software program is to pass through calling under IAR EmbeddedWorkbench development environments
What the C programmer that the API of Zigbee protocol stack writes was realized.Because Zigbee has telegon, router, 3 kinds of terminal device
Different equipment, but due to the simple Star Network that the system uses, so program is divided into coordinator process and terminal is set
Standby program, the program of distinct device handle different things respectively.The signal that terminal equipment control receives is divided into telegon hair
The trigger signal of Zigbee wireless signals, the radon consistence data that RAD7 is sended over by serial ports and the infrared sensor brought
3 kinds.Zigbee wireless signals are divided into control RAD7 and two kinds of control relay again, be respectively to RAD7 send reading order and
Control the closing of alarm lamp.It can be judged when controller receives the radon consistence data that RAD7 sends over, judge whether to surpass
Threshold value is crossed, then decides whether to trigger alarm lamp；Judge whether infrared sensor triggers simultaneously, decide whether radon consistence data
It is sent to telegon.Just need the data of radon consistence being sent to telegon when having staff in room.
As shown in figure 4, the signal that coordinator unit receives is divided into the control command and terminal that Pc is sended over by serial ports
The Zigbee wireless signals that equipment sends over.
As shown in figure 5, the upper computer software of the system is under Microsoft Visual Sudio2012 development environments
Realized with C# language.The time cycle for reading RAD7 data can be set on software interface, and so each cycle can be to string
Mouth sends the order of a reading RAD7 data.And when software receives the data that serial ports sends over, application program will divide
Data are analysed, the radon consistence of RAD7 measure and the signal of infrared sensor of corresponding terminal equipment is obtained, passes through infrared sensor
Triggered time can be obtained by the time that testing person enters and leaves.People will be deposited by having obtained these data-applications
Effective dose is calculated in database, after being provided with to use.
