The foregoing technical solutions of the embodiments of the present utility model will be described in detail with reference to specific application examples, and reference may be made to the foregoing related description for details of the implementation process that are not described.

As shown in fig. 1, an embodiment of the present utility model provides a radiation detection system, including a radiation detection device disposed at a radiation sampling site and a background terminal disposed outside the radiation sampling site; the radiation detection device is connected with the background terminal in a wireless communication mode.

The method comprises the steps of placing a radiation detection device on a nuclear equipment site of a nuclear plant, namely a radiation sampling site, acquiring the radiation quantity in the environment by the radiation detection device, outputting the radiation quantity to a background terminal arranged outside the radiation sampling site in a wireless transmission mode after the radiation quantity is processed by the radiation detection device, and displaying the radiation condition in a display device of the background terminal in various forms, such as a chart after the background terminal receives information, so that the wireless monitoring of the radiation quantity on the nuclear plant site is realized when the nuclear equipment is subjected to power failure maintenance.

The radiation detection device of the embodiment of the utility model is a wireless small device, and the device is placed in a place where radiation needs to be collected, so that the collection of site radiation can be realized. One radiation detection device cannot detect the radiation of the whole nuclear plant, so that in order to ensure that nuclear equipment monitors the radiation monitoring of the whole nuclear plant when power failure overhauls, a plurality of monitoring points, namely a plurality of nodes, are required to be arranged, and one radiation detection device is arranged on each node. The embodiment of the utility model is provided with 20 nodes, each node is provided with a radiation detection device, and the transmission distance of each wireless node is 100-200 meters.

Further, as shown in fig. 1, a gateway is further disposed between the radiation detection device and the background terminal; the gateway is connected with the radiation detection device in a wireless communication mode; the gateway is connected with the background terminal in a wired communication mode.

The radiation quantity information in the radiation detection device is transmitted to the background terminal in a wireless communication mode after being acquired and processed, and because the interface protocols of the radiation detection device and the background terminal are different when the radiation detection device and the background terminal are communicated, the protocols are required to be converted through a gateway, such as converting data in a wireless communication format into data format of wired communication and the like.

The gateway is connected with the radiation detection device in a wireless communication mode, analyzes wireless data after receiving the data from the radiation detection device, and transmits the data to a background server of the background terminal according to a specified protocol;

In an indoor environment, a low-frequency wireless scheme is selected, and the lower the frequency of the radio is, the stronger the diffraction is, so that the LoRa in the 433MHz frequency band is selected. The common 433M communication scheme has low wireless receiving sensitivity, so that the transmission distance cannot be too far, and the LoRa spread spectrum technology has ultrahigh sensitivity and can realize ultra-long-distance wireless communication.

In one embodiment of the present utility model shown in fig. 5, the charging module charges the battery pack in a USB charging mode, and the charging is convenient.

The radiation monitoring of nuclear equipment of a nuclear plant during power outage overhaul has a limited range of detection radiation of one radiation detection device, so that a plurality of radiation detection devices are required to be arranged. The embodiment of the utility model is provided with 20 radiation detection devices which are all in wireless connection with the gateway, and the gateway can only communicate with one radiation detection device at the same time.
