Embodiment Construction

[0021] Such as figure 1 As shown, the continuous detection system of radon concentration in the surrounding rooms of the radon chamber is composed of PC host computer, Zigbee coordinator, Zigbee terminal equipment, and RAD7 radon detector. Connect the RAD7 radon meter with the terminal device in the wireless sensor network composed of Zigbee through the serial port. The data of the radon meter is first transmitted to the terminal device, and then transmitted to the coordinator device through the Zigbee wireless module, and the coordinator device is transmitted through the serial port. To the host computer of the PC; at the same time, the infrared sensor on the terminal device will also send a sign to the host computer when the inspector enters and leaves the radon room, and the host computer will obtain the time when the inspector enters and leaves the radon room, and the host computer will analyze The final radon concentration data and time data are stored in the database, an...

Abstract

A continuous detection system for radon concentration in rooms around the radon chamber. This system uses Zigbee wireless network technology to realize the communication between multiple RAD7 radon detectors and the host computer; the system uses c# language to write the host computer software, and the Access database records and saves historical data. . Compared with other wireless network technologies, zigbec has the characteristics of short distance, low complexity, low power consumption, low data rate, and low cost, and can be well applied to the continuous detection of radon concentration in rooms around radon chambers. A new method is provided for accurately assessing the working effective dose of radon detector testers.

Description

Technical field [0001] The invention relates to a detection system, in particular to a continuous detection system for radon concentration in a room around a radon chamber. Background technique [0002] The calibration of radon measuring instruments is involved in the measurement of ionizing radiation, and a standard radon chamber with a large volume is usually used. The radon concentration in the room where the radon chamber is placed is likely to be high due to the switch operation or the air tightness of the radon chamber. A radon meter can be placed in the room to measure the radon concentration in the room. Due to the uncertainty of the working time and location of the testing personnel in the radon room, this method cannot accurately calculate the impact on the testing personnel. [0003] Zigbee is a short-distance, low-power wireless communication technology. Compared with wireless communication technologies such as Wi-Fi, Bluetooth, and infrared, it is characterized...
