(1) Searching according to an organization:

the company level searches all departments, workshops, routes and equipment data of the company at the level;

the department level searches all workshop, route and equipment data under the department level;

the workshop level is used for searching all routes and equipment data under the workshop;

a route level for searching all device information under the device;

the equipment level searches all measuring point information under the equipment;

according to different concerns, setting different search conditions, namely 'inspection personnel', 'period', 'shift', 'special inspection item', 'processing state', 'abnormal grade', 'data type', 'start and stop', 'normal abnormal', 'in-place' and 'inspection time';

inquiring according to the time detection state, clicking a search box, and displaying running, shutdown, standby and other states, which refer to the running state or the starting and stopping state of the equipment;

in the search box, corresponding search conditions need to be input, and the search needs to be carried out in planning.

Clicking on the search box, a "special tour" query, results in "yes" or "no". In addition, the special inspection item refers to whether the data is obtained by daily inspection or special inspection.

According to the 'type grade' query, different abnormal grades appear when a search box is clicked, and the abnormal grades are divided into an observation grade (normal, serious, slight, general and urgent), a measurement grade (invalid, normal, dangerous, warning, failure, abnormal, early warning, low normal, low early warning, low warning and low danger) and a preset condition grade (normal and abnormal). The abnormal level is a result of comparing the acquired data with a preset limit value and determining the abnormal level.

Counting the point inspection lines:

the line data line is a main line, and information such as the turn, the starting time, the ending time, the number of detected equipment, the number of missed detection equipment, abnormal items, inspection personnel and the like of the line is counted.

Quality personnel management of point inspection:

checking the absent duty data;

the absence of duty refers to the condition that no polling operation exists in a turn, and becomes the absence of duty of polling personnel. The absenteeism is expressed by a chart and a data list through 'searching according to organization conditions' and 'searching according to data conditions';

displaying a chart;

displaying the data;

point inspection missing inspection data:

the missed inspection is the condition that some equipment has no inspection result due to omission, exceeding inspection time and the like in an ethical process, and is expressed by a chart and a data list through 'searching according to an organization condition' and 'searching according to a data condition'.

Displaying a chart;

displaying the data;

counting the time spent in point inspection:

1. the equipment consumes time: and the unit time is divided according to the accumulated statistics of the inspection time of each device. The one-time polling time of the equipment is that the equipment state is selected as the beginning, and the data storage is finished.
