The private key is randomly generated during each job and remains unchanged during the same shipping job. Each collector is provided with an independent ID, the IDs of different collectors are different, and the concentrator can send a private key to the corresponding collector according to the received ID of the collector.

After receiving the ID and the private key of the collector encrypted by the preset public key, the concentrator encrypts the private key by the preset public key according to the ID of the collector and then sends the encrypted private key to the collector corresponding to each ID. And after receiving the private key, the collector decrypts the private key encrypted by the preset public key and sends a private key response encrypted by the private key to the concentrator.

When the concentrator receives the private key response from the collector, the concentrator can judge that the corresponding collector is connected with the concentrator, and the private key can be used for encrypting the data transmission process.

In the present embodiment, the collector 30 includes an acceleration sensor 31, a radiation intensity sensor 32, a temperature sensor 33, a positioning device 34, a power supply battery 35, and a communication module 36. The acceleration sensor 31, the radiation intensity sensor 32, the temperature sensor 33 and the positioning device 34 are respectively used for measuring or acquiring acceleration, overflow radiation intensity, temperature and first position information of the radioactive goods package, and the power supply battery 35 is used for supplying energy to the acceleration sensor 31, the radiation intensity sensor 32, the temperature sensor 33, the positioning device 34 and the communication module 36 to keep normal operation. The communication module 36 is used to send acceleration, spill radiation intensity, temperature, first location information, etc. to the concentrator 40. In addition, the collector 30 can receive the warning message from the concentrator 40, so that the relevant staff can determine the accident type and position.

The server 50 includes a memory 51, an information delivery module 52, and a logic determination module 53. The memory 51 is used for storing the first state data, the first radiation data and the second radiation data from the concentrator 40, and a computer program and the like required by the logic determination module 53. The information transmission module 52 is configured to receive the first state data, the first radiation data, and the second radiation data from the concentrator 40, receive information from the logic determination module 53, and send a radiation reminding message, an early warning message, and the like to the concentrator 40. The logic judgment module 53 is configured to obtain the first state data, the first radiation data, the second radiation data, and the like in the memory 51, and perform logic judgment.

The foregoing is a preferred embodiment of the present application and is not intended to limit the scope of the application in any way, and any features disclosed in this specification (including the abstract and drawings) may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
