Technical Field

The invention relates to a control circuit, in particular to an intermittent start integrated control circuit.

Background

The intermittent production process, also known as a batch production process, is a production method widely used in industrial production and occupies a large proportion. The control of a batch process is called batch control. According to the degree of automation of the batch production process, the batch control system can be roughly classified into the following three types: sequential intermittent control, program intermittent control and comprehensive intermittent control.

Any one process is subject to "disturbances" that cannot be directly controlled, which often change the load of the material or heat produced, so called "load variation", and the control system minimizes the effect of the disturbance on the controlled variable by adjusting the control variable.

Many existing intermittent start integrated control circuits are controlled by adopting a time-base chip NE555 to be matched with a relay, the actual fact is that a timer is adopted, but the design of the chip NE555 is adopted, so that on one hand, the cost is high, and on the other hand, the anti-interference capability is weak.
