Health archives realize the electronic management of various kinds of equipment management archives, and are to realize that technical resource is shared in intra-company.
(2) systems organization
The system function is carried on the back based on equipment account and management regulation, using SQL Server Database Systems as data
Scape relies on .Net frame, and using Object-Oriented Design (OOA) technology, service-oriented (SOA) technology, building is with equipment account
Main interface, integration equipment file administration and equipment flowsheet manage the equipment Information Management System of two basic components, and there are function
Energy expansion interface, the foundation for equipment KPI key index system, device intelligence management system from now on lay the foundation.
System includes two parts:
Using database server as the equipment management integrated information platform (main website) of core；
The equipment routing inspection APP (mobile terminal) installed on each equipment routing inspection personnel mobile phone.
(3) hardware deployed environment
Master device includes: data server 3, service server 2, the network equipment and client computer device etc..
In each workshop of water factory, erection of equipment Wifi router, patrol officer the overlay area Wifi can by mobile phone with
Main website server communication carries out data interaction.
In the water intake pumping station far from our department, water factory, then wechat platform is logged in by Internet network by 3G/4G network,
Realize the data interaction with main website server.
(4) software deployment environment
Equipment information management platform uses B/S three-decker, and the company that SQL Server stores each functional department's input sets
Standby information, as the data supporting of WEB server, middle layer is WEB service, the request from client is handled, according to business
Logic needs extraction process data, front-end user interface from database to realize by client browser.WEB service system
Structure is as shown in Figure 4.
Equipment Information Management System is using the SQL Server database in System of Water Factory as data platform, and structure is such as
Shown in Fig. 5.
(5) system function design
A. equipment account
Equipment account is the main interface of corporate device daily management, main presentation three parts content:
Equipment inventory: the main information of fast browsing company production equipment in the form of list；
Flow tracking: device management operations process and equipment resume are tracked and is shown；
Report management: report management column provides the daily generation for reporting report, export or printout；
B. equipment is filed
Equipment is filed point three kinds of states:
Pre-managing state: equipment application was purchased to the check and accepting storing stage, stressed procurement process tracking and record；
Ordinary management state: equipment storage and installation and operation stage, stress assets and record management, record；
It seals keeping state up for safekeeping: after equipment scrapping, exiting ordinary management, which is sealed up for safekeeping for future reference.
C. inspection is maintained
Inspection maintenance is a kind of routine equipment inspection and maintenance, and a part of equipment is conserved by water factory oneself inspection；It is another
Part professional equipment entrusts specialized company's inspection maintenance, and the emphasis of management is that tracking in advance is reminded and post-hoc tests record, inspection
The execution of maintenance uses work order system, using work order as the carrier of circulation information, records and feed back the executive condition of inspection maintenance, and
It keeps on file as traceable file.
D. equipment is reported for repairment
Equipment reports a point two types, prediction/preventative maintenance and breakdown maintenance for repairment.Prediction/preventative maintenance is to guarantee
The maintenance that equipment is reliable, stable operation carries out；Breakdown maintenance is the maintenance of progress of resuming operation for equipment.
Predictability is reported for repairment to be operated according to general traffics, i.e., first reports for repairment, and → through examination & approval → process repaired again carries out.
Rush repair is then according to reporting for repairment → repairing → mends single process and carries out.The emphasis of equipment complaint management is reception, worksheet processing and inspection
Record.
E. change management
Equipment changes from declaring to fulfiling assignment the operation of each node and Constraints Management, general flow in process every time
As shown in Figure 6.
