1.Introduction

In recent years,accidents in the coal mine industry in my country have occurred every year.Even though the government and various units have issued relevant safety documents,there are still no actual actions in terms of

specific safety hazards investigation and management[1-2],supervision is not in place,and management methods are backward.Such problems,and such post-accountability handling methods,are likely to cause the relevant departments to get lucky,and may even cause greater accidents in the future.

Recently,due to the maturity of modern high-tech such as information technology,the number of users of mobile applications is very large,and it has gradually penetrated into all aspects of the entire economy and society.All walks of life are using information technology to arm themselves.According to the existing problems of fire safety,Wu Qiming[3]and others designed the fire safety hazard reporting APP,but due to the difference between fire protection and coal mining industry,it cannot be used directly,and they proposed that the hidden hazard reporting mechanism is not convenient for supervision and rectification..In order to improve the efficiency of coal mine safety management,Chen Qing[4]designed a set of closed-loop hidden danger management system to improve the degree of informatization of the coal mine industry.However,in actual construction,using their methods,even if there are hidden dangers in the investigation,there are still deficiencies in the supervision,control,and rectification of hidden dangers.

With the rapid development of computer technology,the use of modern high-tech to solve the above problems is the top priority of the safety management development of coal mine enterprises.Therefore,this paper proposes to build an Ionic-based mobile intelligent hidden danger investigation and control system[4].The system integrates real-time entry and upload of hidden dangers,assignment of hidden dangers,supervision of hidden dangers,rectification,review,performance evaluation,etc.,with closed-loop management as the construction idea,which greatly improves the efficiency of investigation and rectification of hidden danger investigation and control,and is also for managers.Provides rich views and big data functions.

2.System Development Technology

Ionic is a framework for smart component app development based on web technology using html5,css3 and javascript[5].It is a cross-platform hybrid mobile app development framework called hybirdapp framework.Ionic greatly simplifies the APP development of the front-end[6].Ionic focuses on UI interaction between feeling and applications[7],which is irreplaceable by Phone Gap[8]and Cordova.This project uses the Ionic framework to develop this mobile smart security hidden danger APP from the web perspective[9].The client side uses JQuery AJAX technology[10],and the server side uses MVC-based hierarchical design ideas and uses Java language[11]for writing.

3.System Introduction

3.1 Setting up the Organization for the Investigation of Hidden Dangers

The hidden danger investigation system[12]relies on the four levels of the head office,branch,contractor and work team.The head office can browse and manage the hidden danger information submitted by all departments.A branch includes a security department and a business department.It can only manage the hidden dangers submitted by its subordinate departments and can view the hidden danger information of other branches.The contractor belongs to the business department of a certain branch company,receives related hidden danger information and conveys the rectification of its work team.The work team receives the hidden danger information and submits it to the superior for acceptance after rectification.The network architecture at all levels is shown in Figure 1.

3.2 Business Process of Hidden Danger Investigation

The basic business process of hidden danger investigation are as follows:All levels are basically closed-loop management of hidden dangers in accordance with investigation,reporting,recording,governance,acceptance and review.

1)Investigation:General inspection personnel,safety department personnel and business department personnel shall carry out investigations one by one according to the contents of the hidden danger investigation,and if certain items have hidden safety hazards,they will be dealt with.

2)Reporting:When investigators consider that there are hidden dangers when dealing with hidden dangers,they will assign departments on the system or directly submit them to the work team for rectification.

3)Processing:The work team will deal with the hidden danger information after receiving it and submit it to the contractor for acceptance.

4)Acceptance:The contractor and inspectors check and accept hidden dangers.If they are unqualified,they will be rejected for rectification.

5)Audit:Relevant departments will review the hidden dangers after they have passed the inspection and rectification to eliminate the hidden danger information.

3.3 Classification of Hidden Dangers

The hidden dangers[13]in specific construction can be roughly divided into the following four categories[14]:hidden dangers during rectification,repetitive hidden dangers,qualification hidden dangers and overdue rectification hidden dangers.According to the completion status of hidden dangers,it can be divided into hidden dangers that have been rectified and hidden dangers in rectification.

In principle,hidden dangers are submitted by ordinary inspectors,relevant personnel of the security department and relevant personnel of the business department.The rectification of hidden dangers shall be specifically implemented by the work team under the contractor,which shall be reported and checked and accepted in different grades,and the declaration,rectification and acceptance of hidden dangers shall be completed and recorded.

4.The Design of Each Module of the System Function

According to different permissions,the interface display is also different,and the functional scope of each user is shown in Table 1.
