Problems solved by technology

In nuclear power plants, according to the relevant regulations on safety management of nuclear power plants, mobile communication terminals such as mobile phones and PHS that emit radio signals are not allowed to enter the plant. It will cause electromagnetic interference to nuclear primary instrumentation, secondary protection and DCS systems
In order to avoid the above-mentioned electromagnetic interference, on the one hand, the nuclear power plant has carried out corresponding management on the relevant areas, such as setting up prohibited areas for the use of communication terminals, and mobile terminals for sending and receiving two-way communications are not allowed to be used in the prohibited areas; on the other hand, in nuclear power plants Most of the mobile communication systems in China use the paging system, but the paging system is difficult to meet the wireless communication needs of nuclear power plants due to its backward technology and single function

Embodiment Construction

[0055] In order to make the purpose of the invention, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0056] It should be noted that, with regard to the definition of restricted areas and non-restricted areas, the present invention defines areas that are sensitive to electromagnetic compatibility and do not allow the emission of electromagnetic waves or require reduced emission power as restricted areas, and areas that allow normal emission of electromagnetic waves are defined as non-restricted areas. restricted area. That is, in the restricted area, electromagnetic waves will have an impact on electronic equipment, ins...

Abstract

The invention discloses a composite mobile communication method for a nuclear power station. The method comprises the steps of receiving communication signals, comprising coding modulation light signals and / or electromagnetic wave signals, sent by a base station of a restriction area or a non-restriction area, judging the received communication signals, and reducing emission power or not emitting the electromagnetic wave signals if the communication signals are the coding modulation signals or the wireless electromagnetic wave communication signals emitted by the base station of the restriction area. The composite mobile communication method for the nuclear power station meets mobile communication requirements on special occasions on the premise that electromagnetic disturbance is avoided. Further, the invention discloses a composite mobile communication terminal and a composite mobile communication system for the nuclear power station.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a nuclear power plant composite mobile communication method, terminal and system. Background technique [0002] With the development of electronics and communication technology, mobile communication technology has been widely used in daily social life, and has provided great convenience for people's life and production. Nuclear power plants have different potential safety risks from conventional power plants—nuclear safety, that is, once a nuclear accident occurs due to certain reasons (equipment, human factors, management, natural disasters, etc.), it may cause uncontrolled release of radionuclides to the surrounding environment, cause radioactive contamination. Emergency actions different from normal order or normal working procedures to control or mitigate nuclear accidents and reduce the consequences of nuclear accidents, that is, nuclear accident emergency...
