Tank level control system, the high water tank control system of design is as shown in Figure 8.
Tank level control system in the present invention, Single Loop Control System is usually with a regulation on a controlled plant
Device keeps the constant of parameter, and adjuster only receives a measurement signal, and it is exported also only controls an executing agency.
Computer control is different from traditional Analog control, it be using a kind of controlling of sampling, can only be according to the deviation of sampling instant
Value carries out calculating control.Continuous output controlling amount contact control can not be carried out as Analog control.Therefore, to analog quantity control
Integral term and differential term in system must carry out sliding-model control.It can be seen from Digital Signal Processing relevant knowledge, at discretization
Reason：Discrete sampling time KT correspond to continuous time (wherein K is sampling sequence number, and T is the sampling period), be replaced with the form of summation
Integration, differential is replaced in the form of increment, approximate transform can be carried out and obtain：

Sampling period, T was sufficiently small, and above-mentioned result of calculation can reach enough accurately, and discrete control process can be regarded as approximately as continuous control
Process processed.Said process employs whole controlled quentity controlled variables, therefore is referred to as full dose formula or positional PID control calculation.Because being complete
Amount output, so output result is relevant with past state every time, calculating formula is to ekAdded up, workload is big and controller is defeated
The u gone outkThe physical location of corresponding executing agency, when controller breaks down, if output is widely varied, can draw
Being widely varied for executing agency is played, serious production accident is likely to result in.Increment type PID refers to the output of digitial controller only
It is the increment △ u of controlled quentity controlled variablek, when the controlled quentity controlled variable that actuator needs is increment rather than position, increment type PID can be used to calculate
Method is controlled.Can obtain controller by (1) formula is in the output valve of the K-1 sampling instant：
Subtracted each other and arranged by two formulas, can obtain incremental timestamp algorithmic formula is：
In formula,
In above formula, △ ukIt can also be write as following form：
In formula, △ ek=ek-ek-1；I=ek-2ek-1+ek-2=△ ek-△ek-2；I=T/TI；D=TD/T
If there is above formula to can be seen that computer control system using constant sampling period T, once it is determined that A, B, C,
As long as using the deviation of front and rear three measurements, it is possible to obtain controlling increment, compared with position model algorithm, amount of calculation is small
A lot.

Row mechanism is widely varied, and is likely to result in serious production accident；Increment type PID refers to that the output of digitial controller is control
The increment △ u of amount processedk, when the controlled quentity controlled variable that actuator needs is increment rather than position, increment type PID algorithm can be used to enter
Row control；Can obtain controller by (1) formula is in the output valve of the K-1 sampling instant：

In formula, △ ek=ek-ek-1；I=ek-2ek-1+ek-2=△ ek-△ek-2；I=T/TI；D=TD/T。
10. a kind of electrolyte automatic vacuum charging method, it is characterised in that comprise the following steps：
1) automatic detection device power supply, is opened, from screen display self-detection result is touched, enters next step after self-inspection success, if from
Inspection is unsuccessful, then is overhauled according to self-inspection error message；
If 2), during the alarm of electrolyte hopper residue, need to add electrolyte, equipment can then automatically terminate alarm；
3), battery pack to be filled is loaded manually；
4) the dimensional parameters information of battery pack to be filled, is selected：Battery size, appearance and size, cell size and arrangement；Such as
Fruit is the information for continuing to use last filling battery, then numbers automatic plus " 1 ", remaining selection default value；
5) filling process, is started；
6) after filling is finished, device systems automatically save the every terms of information of filling battery pack：Battery pack information, filling starting and knot
The beam time；It can be consulted by touch-screen；If continuing to fill next battery pack, return 2), otherwise can select to treat
Machine and shutdown.
