Referring to fig. 2, an embodiment of the present application discloses a multi-impulse control system, comprising:
and the steam quantity information determining unit 21 is used for acquiring equipment signals of equipment to be controlled, acquiring actual steam consumption and steam generation quantity of the steam equipment in the multi-impulse control system, and determining a target pipe loss according to the difference value of the actual steam consumption and the steam generation quantity.
In this embodiment, it is required to collect the device signal of the device to be controlled, and it is required to be described that, with reference to fig. 3, the usage of the collected device signal is as follows: the steam equipment start-stop signal (e) is fed back to the combustion controller to perform logic operation, and the combustion state of the combustion chamber is controlled by multiplying the combustion controller change value (d 1) by the combustion controller signal (d) plus the vacuum damping equipment start-stop signal (e). The combustion condition of the burner controls the evaporation capacity of water in the boiler, and the multi-impulse control system can realize automatic matching of the evaporation capacity and the steam consumption, so that the stability of the pressure and the water level of the boiler is ensured. The frequency parameter of the water supply frequency converter can be controlled by subtracting the steam drum liquid level signal (a) from the steam quantity signal (f) of other steam equipment and subtracting the steam flow signal (b) of the vacuum conditioning equipment and adding the water flow signal (c) and adding the start-stop signal (e) of the vacuum conditioning equipment and multiplying the change value (d 1) of the water flow signal.
It should be noted that, when the signal of the device to be controlled is collected, the information of the steam quantity of the steam-using device in the multi-impulse control system, such as the actual steam quantity and the steam-producing quantity, needs to be collected, and the actual steam quantity and the steam-producing quantity are subjected to difference to obtain the target pipe loss, where the target pipe loss is the steam loss in the present application.

In this embodiment, the current steam pressure needs to be determined according to the determined target pipe loss, the actual air consumption and the steam production, and it is to be explained that the steam pressure and the steam production are in a direct proportion relationship, the larger the steam production is, the larger the steam pressure is, and the current steam pressure needs to be fed back to the multi-impulse control system after the current steam pressure is obtained, so that the multi-impulse control system adjusts the boiler equipment based on the current steam pressure.
And a device adjusting unit 23, configured to determine whether the throttle opening needs to be adjusted based on the current steam pressure, the vacuum conditioning start-stop signal in the device signal, and the gas flow signal in the device signal.

It should be noted that, the adjustment of the opening of the damper is to adjust the steam pressure, and the steam pressure is related to the steam flow, and the steam flow is related to the steam using device, so that the steam flow needs to be ensured to be stable, that is, the steam pressure needs to be ensured to be stable. In addition, the opening degree of the air door needs to be measured and calculated in advance from full opening to full closing of the air door valve, and the time required for increasing or decreasing each time the air door valve changes is calculated, so that after the opening degree of the air door needing to be adjusted is obtained, effective time counting can be performed, and the multi-impulse control system is more accurate.
And a first damper adjusting unit 24 for increasing the damper opening to the target damper opening when the signal type of the vacuum damping start-stop signal is an opening signal.
In this embodiment, the opening degree of the damper needs to be adjusted in combination with the signal type of the vacuum damping start-stop signal, if the signal type of the vacuum damping start-stop signal is the opening signal, the degree of the current damper opening degree and the target damper opening degree needs to be determined, so as to determine the time required for adjustment, and after determining the time required for adjustment, counting down and forcibly increasing the damper to the target damper opening degree.
And a second damper adjusting unit 25, configured to reduce the damper opening to the target damper opening when the signal type of the vacuum conditioning start-stop signal is a stop signal.
In this embodiment, if the signal type of the vacuum damping start-stop signal is stop, the degree of the current throttle opening and the target throttle opening that needs to be adjusted needs to be determined, so as to determine the time needed for adjustment, and after determining the time needed for adjustment, counting down, and forcibly reducing the throttle to the target throttle opening.
And the first instruction execution unit 26 is configured to, when the signal type of the vacuum damping start-stop signal is an on signal, forcibly increase the water supply amount until the vacuum damping enters a steady state, and execute the steam pressure PID automatic operation instruction and the boiler liquid level three-impulse PID automatic operation instruction.
In this embodiment, if the signal type of the vacuum damping start-stop signal is an on signal, the water supply amount is increased forcibly in the process of increasing the opening of the air door forcibly, so that after the vacuum damping enters a steady state, a steam pressure PID automatic operation instruction and a boiler liquid level three-impulse PID automatic operation instruction are executed, so as to maintain the steady state of the current steam pressure and the boiler liquid level, and keep the steam pressure and the boiler liquid level steady.
And the second instruction execution unit 27 is used for forcedly reducing the water supply amount when the signal type of the vacuum damping start-stop signal is a stop signal until the vacuum damping enters a stable state, and executing the steam pressure PID automatic operation instruction and the boiler liquid level three-impulse PID automatic operation instruction.
In this embodiment, if the signal type of the vacuum damping start-stop signal is a stop signal, the water supply amount is forcibly reduced in the process of forcibly reducing the opening of the air door, so that after the vacuum damping enters a steady state, a steam pressure PID automatic operation instruction and a boiler liquid level three-impulse PID automatic operation instruction are executed, so as to maintain the steady state of the current steam pressure and the boiler liquid level, and keep the steam pressure and the boiler liquid level steady.
Therefore, in this embodiment, after determining the current steam pressure, it is necessary to combine the current steam pressure, the vacuum conditioning start-stop signal and the gas flow signal to determine whether the throttle opening needs to be adjusted. If the opening degree of the air door needs to be regulated, the opening degree of the air door is regulated by combining a vacuum damping start-stop signal, and the water supply quantity is correspondingly regulated, so that the steam pressure and the boiler liquid level are kept stable. In this way, the boiler equipment is controlled by combining the acquired equipment signals, so that the boiler equipment can be adjusted in real time, and the phenomenon of unstable steam pressure and boiler liquid level caused by the postponement of the equipment signals is avoided.
