The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the default value detection of digital control system in nuclear power plant of the present invention and the system chart of setting device one embodiment;
Fig. 2 is the default value detection of digital control system in nuclear power plant of the present invention and the process flow diagram of method to set up.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, the default value of digital control system in nuclear power plant 1 of the present invention detect and an embodiment of setting device 2 in, should be noted that, annexation in all diagrams of the present invention between each equipment is the needs for clear its information interaction of explaination and control procedure, therefore annexation in logic should be considered as, and physical connection should be do not only not limited to.This default value detects and setting device 2 mainly comprises four parts: network signal detection module 21, hardwire signal detection module 22, sensor signal module 23 and default value are provided with module 24.
Network signal detection module 21 detects the signal of network delivery, the default value unification of this type of fault-signal is set to " 0 ", do not do ineffectivity at receiving end (non-safe level digital instrumentation control platform 11) and judge, do not do the setting that extra function logic goes to realize other type of this type of default value.Compare the nuclear power Digitizing And Control Unit, in the Digitizing And Control Unit of other industry, usually when signal when different rack rooms carry out network delivery, send the rack dropout, accept rack and will preserve the effective value in a moment, consider the singularity of nuclear power Digitizing And Control Unit, constitute by safe level digital instrumentation control platform 12 and non-safe level digital instrumentation control platform 11, signal of interest connects by hardwire, what network signal transmitted generally is and the irrelevant signal of unit safety State Control monitoring, and the 1E level (safe level) by gateway transmission generally is a redundant configuration to the signal of SR level (safe correlation level) and NC level (non-safe level), therefore this type of fault-signal is provided with the inside unification at default value and is set to " 0 ", does not need extra function logic could realize the different types of setting of this default value.This type of signal is not done extra setting, is connected changing hardwire into the influential signal of interest of nuclear safety determining.
Hardwire signal detection module 22 detects the signal that rack room transmits by hardwire, this signal can be the signal of transmission between safe level digital instrumentation control platform 12 and the non-safe level digital instrumentation control platform 11, or the signal of transmission between non-safe level digital instrumentation control platform 11 and the non-safe level digital instrumentation control platform 11, its receiving end is non-safe level digital instrumentation control platform 11.After detecting this hardwire signal, need carry out ineffectivity to signal and judge that when signal was confirmed to be invalid signals, this type of signal will be provided with default value, and this signal be carried out parametrization handle, the output default value.
After detecting non-safe level digital instrumentation control platform 11 direct sensor signals of gathering, to carry out ineffectivity to this sensor signal in the transmittance process and judge, when signal is confirmed to be invalid signals, carry out the default value setting, and to carry out parametrization to this signal and handle, the output default value.
To detecting the signal that is sent to safe level digital instrumentation control platform 12 and non-safe level digital instrumentation control platform 11 simultaneously, the signal that collects by semiconductor detector 13 normally from nuclear safety sensor 14, both be sent to safe level digital instrumentation control platform 12 by hardwire, also be sent to non-safe level digital instrumentation control platform 11.When semiconductor detector 13 loses LNA; LNB; the power supply power supply of LNC or LND (power supplies of four protection groups of nuclear island); or when situation such as breaking down in the hard wired connection; signal is not provided with default value at non-safe level digital instrumentation control platform 11 receiving ends; judge but will carry out ineffectivity, default value is set at non-safe level digital instrumentation control platform 11 receiving ends.
In sum, the default value detection of digital control system in nuclear power plant of the present invention and method to set up and device are in conjunction with the characteristics of digital control system in nuclear power plant and the singularity of nuclear power security requirement, develop ineffectivity and detect and the default value method to set up, can make things convenient for and optimize the detection and the parameter setting work of default value.
The default value of digital control system in nuclear power plant as shown in Figure 2 detects and method to set up, and it mainly may further comprise the steps:
S1: detect the network failure signal that non-safe level digital instrumentation control platform receives, and in described non-safe level digital instrumentation control platform, be set to " 0 " with the corresponding default value of described network failure signal;
