Description

Equipment start and stop control method and device, computer equipment and storage medium

Technical Field

The present application relates to the field of electrical equipment technologies, and in particular, to a method and an apparatus for controlling start and stop of an apparatus, a computer apparatus, and a storage medium.

Background

In industrial production represented by a large power plant, a control system often needs to externally apply work through a control device to realize pressure maintenance, liquid level maintenance and the like of the system. In consideration of economy and reliability, the control system usually needs to control a plurality of devices to start and stop in the process of realizing pressure maintenance or liquid level maintenance.

Taking the pressure maintaining control process of the medium-pressure system of the power plant as an example, the pressure of a balance gas tank is maintained by four air compressors, and when a first-level low-pressure signal of the pressure of the balance gas tank is received, the air compressor with the priority of 1 is started; when a secondary low-pressure signal for balancing the pressure of the air tank is received, starting an air compressor with the priority of 2; when a three-level low-pressure signal for balancing the pressure of the air tank is received, starting an air compressor with the priority of 3; when receiving the balanced gas pitcher pressure level four low pressure signal, start the air compressor machine that the priority is 4, in the same way, when the signal that the relevant pressure is low is replied, stop the air compressor machine in proper order.

Taking a power plant leakage drainage system as an example, four leakage drainage pumps are arranged in one water collection well to maintain the water level of the water collection well, and when a signal that the water level of the water collection well is higher by one level is received, the leakage drainage pump with the priority level of 1 is started; when a secondary signal that the water level of the water collecting well is high is received, starting a leakage draining pump with the priority of 2; when a three-level signal that the water level of the water collecting well is high is received, starting a seepage drainage pump with the priority of 3; and when receiving a water level four-level signal of the water collecting well, starting the leakage draining pump with the priority of 4, and in the same way, when the related water level four-level signal is reset, stopping the leakage draining pump in sequence.

In conventional methods, the start-stop logic is typically customized by the equipment manufacturer according to a specific scenario. However, in actual industrial production, when the number of devices participating in start-up and shut-down increases, the control logic design of the control system is complex, and errors are easily generated by adopting a traditional customization method, so that control logic disorder is caused, and further, potential hazards are brought to safe production.

FIG. 4 is a schematic diagram of the control logic for a positive storage medium pressure air compressor system. According to fig. 4, the overall logic may be: the starting priority of the air compressor in the automatic mode can be selected through a public LCU monitoring screen or an upper computer of the whole plant, and 5 kinds of selections are set:

sequence 1: starting air compressors 1-2-3-4 in sequence;

sequence 2: starting air compressors of No. 2-3-4-1 in sequence;

sequence 3: starting air compressors No. 3-4-1-2 in sequence;

sequence 4: starting the No. 4-1-2-3 air compressors in sequence;

sequence 5: circularly switching the sequence 1-4 (the PLC performs shift processing, and the actual priority is displayed on the upper computer);

after the PLC is started, the circular switching is selected by default.

One cycle refers to the lowering of the equilibrium tank pressure from the normal pressure level to a low pressure and the return to the normal pressure level. Each air compressor is provided with an automatic starting function and a function of starting or quitting. When the automatic combined starting is put into use, the air compressor can be started according to the priority; when the automatic combined start exits, the air compressor is not automatically started any more, and the air compressor can be manually started and stopped by a person on duty at the moment. When a certain air compressor is unavailable, the automatic starting function of the air compressor automatically quits.

As shown in fig. 4, the priority calculation algorithm may set three registers U \ V \ W, where the register U is used for priority selection, the register V is used for automatic startup availability judgment, and the register W is used for actual priority calculation.

When a certain device is available and automatic joint start is started, the corresponding position of the register V is assigned to be 1, and when a certain device is unavailable or automatic joint start is stopped, the corresponding position of the register V is assigned to be 0.

When V1-V4 are all 0, shift 1 to U1 position.

When the device start-up sequence is 1-2-3-4 and V1=1, shift 1 to the U1 position; when the device start-up sequence is 1-2-3-4 and V1=0, 1 is shifted to the right to the Un position corresponding to the next Vn = 1.

When the device start-up sequence is 2-3-4-1 and V2=1, shift 1 to the U2 position; when the device start-up sequence is 2-3-4-1 and V2=0, 1 is shifted to the right to the Un position corresponding to the next Vn = 1.

When the device boot sequence is 3-4-1-2 and V3=1, shift 1 to the U3 position; when the device start-up sequence is 3-4-1-2 and V3=0, 1 is shifted to the right to the Un position corresponding to the next Vn = 1.

When the device start-up sequence is 4-1-2-3 and V4=1, 1 is shifted to the U4 position. When the device start-up sequence is 4-1-2-3 and V4=0, 1 is shifted to the right to the Un position corresponding to the next Vn = 1.

When register Vn =0, the corresponding Wn is assigned 0.

When U1=1 and V1=1, W1= V1.

When U1=1 and V2=1, W2= V1+ V2.

When U1=1 and V3=1, W3= V1+ V2+ V3.

When U1=1 and V4=1, W4= V1+ V2+ V3+ V4.

When U2=1 and V1=1, W1= V1+ V2+ V3+ V4.

When U2=1 and V2=1, W2= V2.

When U2=1 and V3=1, W3= V2+ V3.

When U2=1 and V4=1, W4= V2+ V3+ V4.

When U3=1 and V1=1, W1= V1+ V3+ V4.

When U3=1 and V2=1, W2= V1+ V2+ V3+ V4.

When U3=1 and V3=1, W3= V3.

When U3=1 and V4=1, W4= V3+ V4.

When U4=1 and V1=1, W1= V1+ V4.

When U4=1 and V2=1, W2= V1+ V2+ V4.

When U4=1 and V3=1, W3= V1+ V2+ V3+ V4.

When U4=1 and V4=1, W4= V4.
