It is the method that the embodiment of the present invention provides unit allocation under a kind of nuclear power plant DCS fault conditions referring to Fig. 1, Fig. 1
Schematic flow diagram.The method of unit allocation may include following steps under nuclear power plant's DCS fault conditions as shown in the figure：
The method of unit allocation is applied in nuclear power plant system under nuclear power plant's DCS fault conditions, after nuclear power plant system includes
Standby control system, master control system and reactor circuit, backup control system and master control system respectively with reactor circuit
Connection.
In a step 101, when the control system of reactor circuit is master control system, real-time judge master control system supplies
Whether electricity is normal, if so, 102 are thened follow the steps, if it is not, thening follow the steps 105a.
Step 101 is specially：When the control system of reactor circuit is master control system, real-time judge master control system
Power supply voltage whether in pre-set interval.
In a step 102, judge whether the control function of master control system is normal, if so, 103 are thened follow the steps, if it is not,
Then follow the steps 105a.
Step 102 is specially：Whether the key modules of master control system are normal, and key modules include operating terminal, main place
Manage device and main memory.
In step 103, judge whether the communication function of master control system is normal, if so, 104 are thened follow the steps, if it is not,
Then follow the steps 105a.
Step 103 is specially：Judge whether the connection of master control system and default access point is normal.
At step 104, judge whether the environment temperature of master control system is normal, if so, 105b is thened follow the steps, if
It is no, then follow the steps 105a.
Step 104 is specially：The environment temperature that master control system is obtained by temperature sensor, judges master control system
Whether environment temperature is normal.
In step 105a, the control system of reactor circuit is switched to backup control system by master control system.
Since any Rule of judgment is unsatisfactory in step 101 to step 104, illustrate that master control system breaks down, therefore
It needs the control system of reactor circuit being switched to backup control system by master control system at this time, to ensure the safety of unit
Property.
In step 105b, control of the master control system to reactor circuit is maintained.
Since all Rule of judgment are satisfied by step 101 to step 104, illustrate that master control system does not break down, therefore
It is not necessarily to the control system of reactor circuit being switched to backup control system by master control system at this time.
It is the method that the embodiment of the present invention provides unit allocation under a kind of nuclear power plant DCS fault conditions referring to Fig. 2, Fig. 2
Another schematic flow diagram.The method of unit allocation may include following steps under nuclear power plant's DCS fault conditions as shown in Figure 2：
In step 201, when the control system of reactor circuit is master control system, the power supply of master control system is obtained
The voltage of power supply.

The voltage of a power supply.
In step 202, whether voltage is judged in predeterminated voltage section, if so, 203 are thened follow the steps, if it is not, then executing
Step 208a.
Step 201 is specially：Judge the voltage of multiple power supplies whether a pair of with the voltage one of multiple power supplies
The multiple predeterminated voltage sections answered.
Wherein, step 201 to step 202 is the specific implementation procedure of the step 101 in Fig. 1.
In step 203, judge whether operating terminal, primary processor and the main memory of master control system are normal, if so,
204 are thened follow the steps, if it is not, thening follow the steps 208a.
Step 203 includes step 203a, step 203b and step 203c.
203a. judges whether that two operating terminals of at least master control system are working properly.
Step 203a is specially：Judge whether display function and the instruction of two operating terminals of at least master control system
Whether sending function is normal.
203b. judges whether the primary processor of master control system is working properly.
Step 203b is specially：The second test post is sent to the primary processor of master control system, and judges whether to receive
The second feedback message sent to the primary processor of master control system.
203c. judging whether the main memory of master control system is working properly.
Step 203c is specially：Judge that the preset data in the main memory of master control system can be read.
In step 204, test is generated to instruct so that master control system sends test post to default access point.
Wherein, access point is preset to connect with master control system, backup control system and reactor circuit respectively.
In step 205, judge whether master control system receives the feedback message that default access point is sent, if so,
Step 206 is executed, if it is not, thening follow the steps 208a.
When master control system receives the feedback message that default access point is sent, illustrate master control system and default access point
Between communication it is normal, master control system can control reactor circuit.
Wherein, step 204 to step 205 is the specific implementation procedure of the step 103 in Fig. 1.
In step 206, multiple temperature of master control system are obtained.
Wherein, master control system distribution and multiple rooms, step 206 are specially：It obtains one-to-one with multiple rooms
Multiple temperature.
In step 207, judge whether multiple temperature are respectively less than temperature threshold, if so, 208b is thened follow the steps, if it is not,
Then follow the steps 208a.
When one or more of multiple temperature temperature is not less than temperature threshold, illustrate the position where master control system
The accidents such as fire may occur, master control system is likely to lose normal control function at this time, therefore need to be by reactor circuit
Control system is switched to backup control system by master control system.
Wherein, step 206 to step 207 is the specific implementation procedure of the step 104 in Fig. 1.
In step 208b, control of the master control system to reactor circuit is maintained.
In step 208a, judge whether the equipment that master control system is related to has nuclear leakage risk.
Wherein, the equipment misoperation or inaccurate operation for having nuclear radiation risk of leakage have nuclear radiation leakage possible, usually
It needs manual operation or the automatic running under artificial monitoring.
In step 209b, if it is not, the control system of reactor circuit is then switched to standby control by master control system
System.
If the equipment that master control system is related to does not have nuclear leakage risk, system is automatically by the control system of reactor circuit
Backup control system is switched to by master control system, control system switching no longer need to manual operation or under artificial monitoring it is automatic
Operation.
In step 209a, if so, sending out nuclear leakage risk alarm.
Step 209 is specially：If so, sending out nuclear leakage risk alarm and showing the nuclear leakage that master control system is controlled
Risk equipment.
Due to there is the equipment of nuclear leakage risk to need manual operation or the automatic running under artificial monitoring, therefore core need to be sent out
Risk of leakage is alarmed so that user obtains nuclear leakage risk information.
In step 2010, nuclear leakage risk process instruction signal input by user is obtained.
After user obtains the information of nuclear leakage risk alarm, input nucleus risk of leakage process instruction is so that control system is cut
It changes in manual operation or the automatic running under artificial monitoring.To improve the reliability of system.
In step 2011, according to nuclear leakage risk process instruction signal by the control system of reactor circuit by main control
System is switched to backup control system.
Wherein, step 208a to step 2011 be step 105a in Fig. 1 specific implementation procedure.
