Description

Nuclear power plant short message transmission method, system, short message server and mobile terminal

technical field

The invention relates to the technical field of wireless communication, and more specifically, relates to a nuclear power plant short message transmission method, system, short message server and mobile terminal.

Background technique

One of the important functions of the wireless communication system of nuclear power plants is to send emergency short messages to the entire nuclear power plant area during emergency response. Since the wireless communication system of the nuclear power plant has three functional divisions: the restricted area, the unrestricted area and the power control area: mobile wireless communication terminals in the restricted area are prohibited from transmitting radio wave signals, and mobile wireless communication terminals can only receive broadcast messages from the base station; the unrestricted area is In the ordinary two-way communication area, the mobile wireless communication terminal works according to the normal nominal transmission power mode of the equipment; the power control area is a low-power two-way communication area, and the mobile wireless communication terminal reduces the wireless transmission power to meet the electromagnetic safety requirements of the corresponding plant area. According to the base station signals of different zones, the wireless communication terminal equipment can automatically switch to the radio wave transmission power mode of the corresponding zone without manual intervention. Therefore, relying on the wireless communication system of the nuclear power plant to send the emergency short message transmission must adopt a proprietary technology. The conventional wireless communication technology that requires two-way communication between the base station and the mobile terminal cannot be sent in all three functional areas of the nuclear power plant. For emergency short messages, the proprietary technology is used to realize that mobile terminals in the three functional divisions of restricted area, non-restricted area and power control area can receive emergency short messages, so as to effectively guarantee the emergency response actions of nuclear power plants.

At present, the operating units of nuclear power plants have higher and higher requirements for the wireless mobile terminals used in the plant. It is required that the wireless mobile terminals should adopt intelligent mobile terminals as much as possible to have a friendly user experience. Realize the convenience of follow-up procurement and avoid the passive situation of locking exclusive suppliers for single procurement. Therefore, the wireless communication technology suitable for the special application scenarios of nuclear power plants and the wireless emergency short message transmission technology based on this technology have become the application requirements of the current nuclear power plant wireless emergency short message.

In order to meet the above application requirements, two solutions are currently used:

The first is to use the dedicated wireless communication technology McWiLL (Multi-Carrier Wireless Information Local Loop) as the wireless communication system of the nuclear power plant, and use a customized non-intelligent mobile terminal. Through the short message one-way reception function of the customized non-intelligent mobile terminal, the transmission of emergency short messages in three functional partitions of restricted area, non-restricted area and power control area is realized.

In this method, the transmission of emergency short messages must rely on proprietary wireless communication technology and customized, non-intelligent push-button mobile terminals. Make a single purchase.

The second is to use the wireless communication technology of general Wi-Fi plus the Internet of Things channel as the wireless communication system of the nuclear power plant, and use an intelligent mobile terminal with an external customized Internet of Things module. In the non-restricted area and power control area of the wireless communication system of the nuclear power plant, emergency short messages are transmitted through the Wi-Fi channel, and in the restricted area of the wireless communication system of the nuclear power plant, one-way transmission is adopted because the Wi-Fi radio frequency of the mobile terminal is turned off for transmission. The IoT channel transmits emergency short messages.

In this method, the intelligent mobile terminal must be externally connected with a customized IoT module, which increases the size and weight of the mobile terminal, and the user has a poor carrying experience, and because the externally customized IoT module shares the battery of the mobile terminal with the mobile terminal, the overall Endurance is reduced. In addition, for external customized IoT modules, nuclear power plant operating units need to make single purchases from exclusive suppliers for a long time.

Source ID Destination ID type timestamp content 0 47 48 95 96 103 104 135 136…

Specifically, Source ID (source ID): sender identity information, length 6Bytes. After the mobile terminal receives the broadcast information, it searches for the corresponding identity through the Source ID, and displays it as the sender of the message (the sender must have been registered in the system).

Destination ID (purpose ID): the identity information of the receiving end, the length is 6 Bytes. By parsing this field, the mobile terminal determines whether the target of the current information is itself, and decides whether to display the content of the information based on this. For broadcast information, this field is FF FF FF FF FF FF, and all mobile terminals that receive this ID need to display this information.

Type: information type, length 1Bytes. The information type is used to indicate that the information is preset information or custom information.

timestamp: timestamp, length 4Bytes. Due to the lack of information confirmation mechanism in one-way communication, in order to ensure that the information is delivered in place, the short message server needs to broadcast the same information multiple times. After the mobile terminal receives and correctly demodulates and displays this information, the information with the same time stamp will no longer be displayed. to avoid displaying the same message frequently.

Content: content field, the length is related to the Bluetooth protocol version. The length of Bluetooth 5.0 version is 239Bytes. The Bluetooth technology can flexibly use the preset information library and custom text information to transmit information. The Content field of the preset information base only contains a specific information serial number, and after parsing, the mobile terminal queries and displays the information corresponding to the serial number from the preset information base. For example: number 0x000A corresponds to the message "Hello!", the sender selects "Hello!" from the existing message list and sends it, the short message server converts this message to 0x000A, and describes it as preset information in the type field ; After the receiving end recognizes the type field as preset information, it will directly search for the information labeled 0x000A from the information database, and display "Hello!". For the custom text message, the sender sends the custom text message, and the short message server transcodes the custom text message, and fills it in the Content field, and the mobile terminal receives and parses it, and transcodes it into text message and displays it according to the content of the Content field.
