Abstract
The invention relates to a seismic instrument system of nuclear power plant, which is mainly used for monitoring the vibration condition of the plant area, the device and the workshop of the reactor structure in the nuclear power plant, responding, providing earthquake information for the operating personnel of the nuclear power plant and deciding the further operation. The invention uses a plurality of sets of sensors which are distributed to different positions of the plant area and the reactor structure workshop of the nuclear power plant for continuously collecting and monitoring the vibration condition of the reactor workshop. Once the generation of earthquake is detected, an alarm signal is transmitted immediately for notifying the operation personnel to adopt an emergency operation,preventing and reducing the damage caused by the earthquake, and ensuring the operation safety of the nuclear power plant. Simultaneously, the system records the whole data in the earthquake generation process and can analyze and evaluate the structure safety of the workshop for providing basis to determine the next-period operation.
Description
Technical field
The present invention relates to a kind of earthquake instrument system that is applied to nuclear power station.
Background technology
According to the requirement of GB 50267-97 " code for seismic design of unclear power plants ", nuclear power station must be provided with earthquake detection and warning instrument.
At present, the sampling of domestic nuclear power station be the external earthquake instrument system of introducing, because of the introduction time early, technology is backward, the accessory costliness is difficult in maintenance.
Summary of the invention
The invention provides a kind of earthquake instrument system that is applied to nuclear power station, satisfy the requirement of GB 50267-97 " code for seismic design of unclear power plants ", be mainly used in the shock conditions and the response that monitor nuclear power station plant area, equipment and reactor structure factory building, the operations staff provides earthquake information to nuclear power station, does the decision-making of further operation.Utilization of the present invention is laid in many sensors of nuclear power station plant area and reactor structure factory building different parts, the shock conditions of continuously gather, monitoring reaction being piled factory building, in case having detected earthquake takes place, send alerting signal at once, notify the operations staff to take emergency operation, avoid and reduce the infringement that earthquake causes, guarantee the security of operation of nuclear power station.Simultaneously, the structural safety of factory building can be analyzed, be assessed to the partial data in the system log (SYSLOG) earthquake generating process, for next stage operational decisions foundation is provided.
The present invention can be the nuclear power station operating personnel following earthquake information is provided:
1. prevent the record of improper shutdown and dangerous continuous operation;
2. the earthquake warning and the data of " checking fast " for the operations staff; According to these data, operating personnel determine the emergency operation that should take and the mode of further moving, and can verify the rationality of nuclear power plant's seismic design;
3. reach the threshold value of design as if earthquake, the seismic analysis of can being correlated with, and provide labor used data.

Accompanying drawing is the block diagram of system.
Among the figure: 1---information process unit
2---display unit
3---alarm unit
4---the indicating fault unit
5---the signal condition unit
6---the sensor array
7---the Hot Spare subsystem
Embodiment
Structure of the present invention is made up of the sensor array 6, signal condition unit 5, information process unit 1, Hot Spare subsystem 7, display unit 2, alarm unit 3 and indicating fault unit 4 as shown in drawings.
Be distributed in the sensor array 6 of nuclear power station different parts, shock conditions is converted to electric signal, after signal condition unit 5 is handled, send into information process unit 1 and analyze, judge, preserve, and present to the operations staff at display unit 2; When monitoring earthquake when taking place, information process unit 1 gives the alarm to the operations staff by alarm unit 3, so that take emergency measures, reduces earthquake disaster.The vibration signal of part significant points after signal condition unit 5 is handled, also sends one the road to 7 storages of Hot Spare subsystem, prevents from that information process unit 1 from breaking down to cause loss of data.Simultaneously, system constantly carries out self check, provides failure message by indicating fault unit 4.
Claims (3)
1, a kind of earthquake instrument system that is applied to nuclear power station is characterized in that:
Lay many sensors at nuclear power station, the shock conditions of monitoring plant area, building structure and equipment takes place in case detect earthquake, sends alerting signal, and record data.
2, the described seismic instrument system of nuclear power plant of claim 1 is characterized in that:
Geological data according to record carries out the earthquake correlation analysis.
