Problems solved by technology

[0002] The downtime rate is an important data to reflect the operation of the equipment. The formula is downtime rate=total downtime / total running time*100%. At present, the downtime rate calculation of the silk production line of cigarette industrial enterprises basically uses manual recording of downtime, and uses system time Instead of running time, the calculated downtime rate is not objective, the accuracy rate is not high, and it cannot truly reflect the production and operation of the equipment

Embodiment Construction

[0021] A silk-making equipment shutdown rate calculation system based on a real-time database. The system includes a data acquisition system, a data storage system, and a data analysis and calculation system. The present invention is equipped with a belt conveyor in each process section of the silk-making workshop and is installed at the entrance With the electronic belt scale, the data acquisition system collects the instantaneous flow rate of the electronic belt scale, and stores the instantaneous flow into the data storage system. The data storage system uses a real-time database. The data analysis and calculation system retrieves the data from the real-time database and stops the machine in the following ways Rate calculation:

[0022] 1. Equipment running time

[0023] Equipment running time = end time of incoming material-start time of incoming material;

[0024] Silk production is organized in the form of work orders. The start time and end time of each work order are recorde...

Abstract

The invention relates to a tobacco cutter outage rate calculation system based on real-time database. The system comprises a data acquisition system, a data storage system and a data analysis calculation system. The data acquisition system acquires instantaneous flow of an electronic belt scale. The instantaneous flow is stored in the data storage system which is a real-time database. The data analysis calculation system calls data of the real-time database to calculate outage rate according to: 1, equipment running time = feeding stop time - feeding start time; 2, equipment outage time; 3, equipment outage rate = total outage time / total running time * 100%. The data source for the system is from the equipment real-time database; the data obtained by the system is more objective than that obtained by manual recording, with high accuracy and low labor; the system provides more reliable data basis for equipment management staff to arrange equipment operation and maintenance plans.

Description

Technical field [0001] The invention relates to the automatic collection of the running time and the downtime of the silk-making equipment of the cigarette enterprise and the calculation of the downtime rate. Background technique [0002] The downtime rate is an important data reflecting the operating conditions of the equipment. The formula is downtime rate=total downtime / total running time*100%. At present, the calculation of the downtime rate of the silk-making section of cigarette industry enterprises basically adopts manual recording of downtime and uses system time Instead of running time, the calculated downtime rate is not objective, the accuracy rate is not high, and the equipment production and operation conditions cannot be truly reflected. [0003] Real-time database (RTDB-Real Time DataBase) is a branch of database system development, which is produced by combining database technology with real-time processing technology. An important feature of real-time databases is...
