Embodiment Construction
[0023] Such as figure 1 Shown is a structural block diagram of a preferred embodiment of the control system allowing operation of the console in the main control room of the nuclear power plant according to the present invention. The control system in this embodiment includes a first column permission switch unit 1 , a second column permission switch unit 2 , a first column operation switch unit 3 , a second column operation switch unit 4 , a receiving processing unit 5 and an actuator unit 6 .
[0024] The power supply circuit of the console in the main control room of the nuclear power plant is divided into the first column power supply branch and the second column power supply branch. In order to realize the isolation of the first column power supply branch and the second column power supply branch, it is necessary to The unit that allows the switch and the unit that operates the switch are provided separately. That is, on the first column power supply branch, the first co...

The invention relates to a control system and control method for operation and allowance of console in main control room in nuclear power station. The control system comprises a first-column allowing switch unit, a second-column allowing switch unit, a first-column operating switch unit, a second-column operating switch unit, a receiving and processing unit and an executing mechanism unit. The control method comprises the steps of judging whether an allowing command and an operating command of power supply devices in the same column are received or not, if so, sending an executing command andexecuting the operation according to the executing command. The control method can realize two-step operation of firstly allowing and then operating of the console of the main control room of the nuclear power station, reduce the probability of misoperation, avoid the operation failure of the whole column of equipment due to the faults of the allowing switches, meet the single fault criterion andimprove the reliability of operation of the nuclear power station.
Description
technical field [0001] The invention relates to the technical field of nuclear power plant control, and more specifically relates to a control system and a control method for operating a console in a main control room of a nuclear power plant. Background technique [0002] At present, most of the operating equipment of the console in the main control room of nuclear power plants are equipped with switches that combine knobs and buttons. For switches that are turned or pressed to issue commands immediately, the probability of misoperation is greatly increased. At the same time, according to the operation specification, it is required that the operating equipment must realize the two-step operation of "permit first and then operate", so that the operator must perform two actions before issuing an execution command to prevent misoperation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control system and a contro...
