2) Selecting equipment and logic elements which are consistent with the data improvement in the step 1) to form group control, equipment linkage, alarm feedback and other logic designs. In this section, a chain logic design among a large number of devices is often involved.
3) And (5) carrying out design verification, and if the defects exist, returning to the step 2) to change the design again. If there is no defect, the next design stage is entered.
The current technical scheme mainly has the following defects:
1. in the process of logic design of a nuclear power plant, the same control strategy and logic design schemes of instrument equipment are adopted in a large number (for example, ventilation systems of various plants have high similarity), and designers adopt different design methods when implementing, so that unpredictable errors exist in the design process of a control logic diagram.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

TABLE 1
Wherein:
(1)2X 100% burst configuration typical control logic
As shown in fig. 2(a) -2 (c), 2 × 100% devices are set as a-column and B-column devices. When the group operation is carried out, an operator needs to manually set the priority-started column on the second layer (if the operator is not set, the master control generates an alarm), and after the group control on command is sent, the priority-started column is set to run. If the equipment of the running train fails, the running of the standby train is automatically switched to.
(2)3X 100% burst configuration typical control logic
3X 100% ganged typical control logic is commonly used in systems with three columns of redundant devices. The process trains controlled by the groups typically have similar equipment, control requirements, and can perform approximately the same function. Three columns are independent of each other, and the air conditioning capacity of the system cannot be lost due to the fact that any one column fails.
The 3X 100% burst configuration control charts are shown in fig. 3(a) -3 (c), for example.
(3) Type 1 and Type 2 Type electrical plus typical control logic
Electric heaters with local control cabinets are classified into several standard modes depending on the control manner and requirements.
Type 1: the method is mainly used for controlling the non-safety switch type electric heater. In order to meet the room temperature requirement, the start and stop of the electric heater can be controlled according to the temperature signal, the function of automatically starting the electric heater when the temperature is low and automatically stopping the electric heater when the temperature reaches a set value can be realized, and meanwhile, the manual start can be realized. The control schematic diagram is shown in fig. 4.
Type 2: the method is mainly used for controlling the safety-level switch type electric heater. In order to meet the room temperature requirement, the start and stop of the electric heater can be controlled according to the temperature signal, the function of automatically starting the electric heater when the temperature is low and automatically stopping the electric heater when the temperature reaches a set value can be realized, and meanwhile, the manual start can be realized. The control principle is consistent with Type 1.
Typical control schemes for Type 1 and Type 2 electric heaters are shown in fig. 5, for example.
(5) Type 3 and Type 4 Type electrical plus typical control logic

The local control cabinet only comprises an electric heater power regulator, and a specific regulating loop is realized by an external controller. The power regulator receives the 4-20 mA regulating instruction and displays fault lamp information of the power regulator. The control principle is consistent with Type 3. Typical control illustrations for Type 3 and Type 4 electric heaters are shown in fig. 7.

A typical control diagram for the smoke evacuation valve is shown in figure 9.
6) Control logic typical of iodine filtration train configuration manual isolation valve type
Under the normal working condition of the ventilation system, the iodine filtering exhaust bypass does not operate. The iodine filtering exhaust bypass has the main functions of: under the accident condition, exhaust air polluted by iodine is introduced into an iodine filtering bypass, and iodine in the exhaust air is removed through an iodine adsorber, so that the total airborne radioactivity of the exhaust air is limited.
