Method and system for controlling soft shutdown of pharmaceutical equipment

Abstract

The invention discloses a control method for soft shutdown of pharmaceutical equipment, which is applied to the pharmaceutical equipment equipped with a UPS battery pack, and comprises the following steps: when the mains supply is normal, the shutdown process is as follows: the mains supply of the equipment is cut off, the UPS battery pack supplies power and sends a shutdown signal to a controller, and the controller stores various parameters and operation data and sends a shutdown instruction to an industrial personal computer; the industrial personal computer closes the upper computer software, and after the upper computer is shut down normally, the controller sends a shutdown signal to the UPS battery pack to stop power supply; the shutdown process when the mains supply is abnormal is that when the mains supply is abnormal, the UPS battery pack is automatically switched to supply power, and a mains supply abnormal signal is sent to the controller; the controller gives a shutdown alarm and sets shutdown conditions; and if the commercial power is not recovered when the shutdown condition is met, the upper computer executes a software shutdown process, and after the shutdown of the upper computer is completed and a period of time is delayed, the UPS battery pack automatically stops supplying power. The method has the advantages of realizing soft shutdown of equipment, guaranteeing data security and the like.

Description

technical field [0001] The invention mainly relates to the technical field of medicine and food packaging, and in particular to a control method and system for soft shutdown of pharmaceutical equipment. Background technique [0002] When the existing pharmaceutical equipment control system shuts down normally, the operator needs to actively stop the software first, shut down the industrial computer system, and finally cut off the power supply. If the operator is not properly trained and cuts off the power of the equipment directly, the power of the industrial computer and the controller will be cut off directly. This operation has great risks, which may cause major problems such as unsaved parameters and loss of production data. [0003] In the event of an abnormal power failure in the existing pharmaceutical equipment control system, if UPS is not configured, the equipment power will be cut off directly. If the system is configured with UPS, the equipment will switch to UPS...

Problems solved by technology

If the operator is not properly trained and cuts off the power of the equipment directly, the power of the industrial computer and the controller will be cut off directly. This operation has a great risk, which may cause major problems such as unsaved parameters and loss of production data.

[0003] In the event of an abnormal power failure in the existing pharmaceutical equipment control system, if UPS is not configured, the equipment power will be cut off directly. If the system is configured with UPS, the equipment will switch to UPS power supply. During the battery power supply process, Some equipment can stop running immediately, but it is necessary to manually stop the software, shut down the industrial computer system, and finally cut off the power; if the operation is wrong, cutting off the power directly will also cause data loss.

In addition, some technological equipment such as dryers, freeze dryers, and isolators cannot be shut down immediately when there is an abnormal power outage. Key data such as temperature, pressure difference, and particle count still need to be monitored, but the system cannot obtain the power of the battery pack. If there is still no power when the battery pack is exhausted, the power of the entire device will be cut off directly

[0004] To sum up, the existing equipment cannot cope with abnormal situations such as personnel operating errors, factory power outages, etc. If an abnormal situation occurs and the power supply of the control system is cut off directly, data may be lost. Data is a very important factor for product production. If Loss of production data, failure to pass GMP review, and untraceable drug production process will result in waste of large quantities of products and immeasurable losses
