Evaluation method for firework gunpowder production safety monitoring equipment

Abstract

The invention discloses an evaluation method for firework gunpowder production safety monitoring equipment. The evaluation method comprises the following steps: 1, obtaining inefficiency c and recovery rate d of each piece of monitoring equipment in a firework gunpowder factory; 2, setting all monitoring equipment to be in a running state in an initial state; 3, setting the interval operation of afailure state and a repair state during operation for each piece of monitoring equipment, wherein the operation time of the failure state is c*a, the operation time of the repair state is d*a, a is arandom number between 1 millisecond and 10 milliseconds, and a is randomly extracted between 1 millisecond and 10 milliseconds when the failure state and the repair state are switched each time; 4, establishing a coordinate system which takes time as an a axis and takes the serial number of each monitoring device as a y axis; and 5, after the a-axis duration time t, counting the total duration t1when the number z of the monitoring devices in the repair state at the same time is greater than or equal to n in the t time period, wherein (t1 / t)*100% is the overall reliability of the monitoring equipment, and n represents a threshold value when the set number of the monitoring devices is the safe operation number.

Description

Technical field: [0001] The invention belongs to the field of fireworks and gunpowder, and in particular relates to an evaluation method for fireworks and gunpowder production safety monitoring equipment. Background technique: [0002] Fireworks and gunpowder are dangerous goods, so multiple monitoring equipment will be set up during production to detect the production process. However, the equipment will have a failure rate and a recovery rate. The failure rate refers to the ratio of the time when the monitoring device itself stops running after failure to the total time; the recovery rate refers to the ratio of the total time of the normal operation time of the monitoring device; The monitoring equipment is in a fault state, and there are always monitoring equipment in the running state. However, when multiple monitoring devices fail at the same time, it will cause large loopholes in the monitoring of fireworks and powder production, which is likely to cause accidents. The...

However, the equipment will have a failure rate and a recovery rate. The failure rate refers to the ratio of the time when the monitoring device itself stops running after failure to the total time; the recovery rate refers to the ratio of the total time of the normal operation time of the monitoring device; The monitoring equipment is in a fault state, and there are always monitoring equipment in the running state, but when multiple monitoring devices fail at the same time, it will cause large loopholes in the monitoring of fireworks and gunpowder production, which is likely to cause accidents. The reliability of the evaluation, thereby reducing the above risks
