Embodiment
In order to make object of the present invention, technical scheme and useful technique effect thereof more clear, below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.Should be understood that, the embodiment of describing in this instructions is only used to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 shows the process flow diagram of a kind of master control room of nuclear power station back-up disk alarm method that the embodiment of the present invention provides, and this alarm method comprises:
Step 101, safe level monitoring cabinet receive safe level technological parameter;
Particularly, by collecting device, the safe level technological parameter of nuclear power plant's collection in worksite is sent to safe level monitoring cabinet, above-mentioned safe level technological parameter can be the temperature parameter of nuclear power station one loop hot-side temperature parameter or three loops.Above-mentioned collecting device can be arranged in nuclear power plant's process system, above-mentioned technological parameter can be in real time or timed sending to safe level monitoring cabinet, such as a circuit pressure signals collecting, by the pressure unit being arranged in a loop voltage stabilizer, gather a circuit pressure signal, be real-time transmitted to safe level monitoring cabinet.
Safe level monitoring cabinet receives after above-mentioned safe level technological parameter, and above-mentioned safe level technological parameter is carried out to isolation processing.Because part signal may be assigned to several different racks simultaneously, for preventing that different rack room signals from being shown in interference, need carry out isolation processing.
Further, above-mentioned safe level technological parameter is simulating signal, and safe level monitoring cabinet receives after the safe level technological parameter of above-mentioned simulating signal, and above-mentioned safe level technological parameter is converted into digital signal from simulating signal.
Step 103, safe level monitoring cabinet compare the threshold value of above-mentioned safe level technological parameter and storage;
Particularly, the threshold value of the pre-stored above-mentioned safe level technological parameter of safe level monitoring cabinet meeting, and the safe level technological parameter of acquisition and the threshold value of storage are compared.Such as a circuit pressure parameter, according to nuclear power plant's service requirement, calculate the loop operating pressure of high permission, be pressure high threshold, in CPR1000 heap type, being set as 16.45MPa, is 16.45MPa therefore safe level monitoring cabinet can be stored the pressure high threshold in a loop.
Step 105, safe level monitoring cabinet generate safe level alerting signal when the described safe level technological parameter of judgement surpasses threshold value;
Particularly, safe level monitoring cabinet compares the safe level technological parameter receiving and the threshold value of storage, if the technological parameter receiving is no more than the threshold value of storage, incites somebody to action not trigger alarm, and when process parameter value surpasses the threshold value of storage, generate safe level alerting signal.Above-mentioned trigger alarm can be the threshold triggers warning that single technological parameter surpasses storage, can be also that a plurality of technological parameters are reported to the police over the threshold triggers of storage.Such as when a circuit pressure collection signal is greater than high threshold 16.45MPa, trigger the high alerting signal of pressure; CPR1000 heap type one circuit pressure has three and measures passage, if there are two passages to collect pressure superthreshold simultaneously, reports to the police, and by three, gets a group alarm signal of logical operation meeting triggering of two.
