Working state recovery method for controlling short-time power failure of equipment through continuous heating

Abstract

According to the working state recovery method for controlling the short-time power failure of the equipment through continuous heating, the working condition is recovered through the PLC of the equipment and the newly-added power failure timer, manual work is replaced, and the cost is low; conditions needing to be judged in the working condition recovery process are judged and the working condition is recovered through the PLC of the equipment and the newly-added outage timer, manual operation is not needed in the recovery process, the recovery efficiency is greatly improved, personnel guarding is not needed, and the beneficial effect of being low in cost is achieved.

Description

technical field [0001] The invention belongs to the technical field of power failure recovery, and in particular relates to a working state recovery method for continuous heating control equipment power failure for a short time. Background technique [0002] For superhard materials, in some production processes that require long-term heating, unexpected power outages will result in defective products, waste products, equipment damage, etc.; when the power grid is powered off due to some problems and then restored, the equipment needs to be restored , Common situations include grid power outages and lightning strikes, which range from a few tenths of a second to more than ten seconds. In order to solve this problem, it is usually necessary to use a UPS power supply. Although using a UPS power supply can prevent power outages, the cost is high. Considering the factory area The power outage time is not long, and the power supply will be restored under normal circumstances for m...

[0002] For superhard materials, in some production processes that require long-term heating, unexpected power outages will result in defective products, waste products, equipment damage, etc.; when the power grid is powered off due to some problems and then restored, the equipment needs to be restored , Common situations include grid power outages and lightning strikes, which range from a few tenths of a second to more than ten seconds. In order to solve this problem, it is usually necessary to use a UPS power supply. Although using a UPS power supply can prevent power outages, the cost is high. Considering the factory area The power outage time is not long, and the power supply will be restored under normal circumstances for more than ten seconds, and the recovery of the working condition after a short period of power failure will not affect the processing of the product, so the working condition can be artificially restored manually. However, manual recovery requires technical personnel to have high experience, and when no one is on duty, failure to recover in time will cause the product to be scrapped
