1. Introduction
1.1 Development background
System name: RFID fixed asset management system[以下简称FAM系统];
The developer is Beijing Chuangyi Information Technology Co., Ltd.;
System users are the staff who use this system;
The fixed asset management system adopts radio frequency identification technology (RFID) and bar code automatic identification technology, collects data in real time through the location reader of the management area, and monitors the movement of fixed assets; use the handheld to count and read the RFID electronic tags attached to the fixed assets in batches, Achieve quick inventory, improve the efficiency and accuracy of inventory; provide daily management of fixed assets, depreciation management and report analysis to ensure the integrity, value preservation and appreciation of fixed assets, correctly calculate the quantity and value of assets, and supervise and promote the proper custody of fixed assets And rational use, continuously improve equipment utilization and intact rate, and give full play to the effectiveness of fixed assets.
Standardize the management of assets. By dividing catalogs, categories, types, etc. to order asset information, the fixed asset management system can make complex definitions of assets to meet the needs of the enterprise, and integrate asset management through the combination with other modules. All information, including manual, department, price, current value, circulation status, person in charge, user, etc. Combined with bar code management, it can further improve the management of asset repair, maintenance, loan, return, and scrap.
Workflow management is adopted to realize the relevant functions of asset purchase, borrowing, inventory, and storage. The fixed asset management system tracks the use of assets throughout the life cycle, and the fixed asset management system provides multiple reports for asset use and circulation. , Depreciation, demand statistics, etc. to make multi-angle analysis to support the enterprise’s asset management.
1.2 Purpose
This article defines the detailed requirements of the FAM system, and clarifies the functional content, functional boundaries, and development approaches of the FAM system. By establishing an effective RFID intelligent management system, using modern computer information technology and advanced RFID technology, convenient and fast data collection and transmission methods and effective and convenient data management methods, provide a convenient and quick way for asset purchase, circulation, inventory and other information The method of recording and querying enables real-time sharing of asset information in handheld terminals and servers, and at the same time ensures that this information can be updated and maintained in a timely manner.
RFID technology is added to the fixed asset management system as an advanced intelligent collection module to realize the effective management of asset purchase, circulation, inventory and other information, so that it is easy to understand the dynamic situation of each asset at any time, and adjust the assets in a timely manner. , To be accurate and efficient.
1.3 Business scope
The RFID fixed asset management system is used to support fixed asset management, including asset management, asset procurement, asset inventory, report management, and system user management.
The RFID fixed asset management system is a desktop application system operated by an administrator.
2. Constraints and assumptions
2.1 Software operating environment and technical constraints
2.1.1 Software constraints
The FAM system is developed using .NET technology. The software environment for development and operation is:
● Development language Microsoft .NET, Framework, C#.NET;
● Support 14 kinds of databases, including SqlServer, Oracle, MYSQL, VF, Access and other common databases;
● Support range Windows desktop version, the web version supports PC browser, responsive cloth type, tablet PC, mobile phone version of WEB.
2.1.2 Asset constraints
The database server is recommended to use at least Intel P4 (1.8G HZ) PC workstation with 1024M memory and 120G hard disk.
2.2 Delivery and deployment constraints
The FAM system must be developed within one month, and an independent exe file must be used as an application release form when it is delivered.
3. Functional requirements
Software system function design:
3.1 System role
FAM is used to manage the fixed assets of business units. Its main functions include asset management, asset procurement, asset inventory, report management, and system user management.
FAM includes three Actors:
(1) Ordinary user (User)
Ordinary users refer to users who do not have management functions in the FAM system and can only view information about fixed assets.
(2) Fixed asset management specialist
(SM) The fixed asset management specialist is mainly responsible for fixed asset management, purchase application, approval, and inventory.
(3) SuperUser
The super user is responsible for system user management and deletion of fixed asset information.
3.2 Requirements description
3.2.1 Asset Maintenance
3.2.1.1 Asset registration
Demand Number: FR-ZCWH-1
Requirement description: After logging in to the system, the fixed asset management specialist can register (new) asset information and support the batch import of templates.
When registering asset information, you need to register the following information: asset certificate, RFID number, equipment serial number, equipment name, equipment model, ownership, asset type, unit of measurement, production date, supply unit, original amount, installation cost, Production unit, user department, person in charge of use, opening time, prescribed service life, used life, ancillary equipment, depreciation rate, status, remarks.
constraint:
● Asset certificate, RFID number, equipment serial number, equipment name, equipment model, ownership relationship, asset type, measurement unit, production date, supply unit, original amount, installation cost, production unit, user department, and person in charge , Opening time, prescribed useful life, used life, depreciation rate, status, cannot be empty;
● The RFID number is the unique identification code of the information, which is assigned in the prescribed order, and the mode is: 8-digit hexadecimal serial number, such as 0000001, 99999999, FFFFFFFF.
● The value of the status is (in use|reported|sold), and the asset registration is forced to be “in use” without modification;
● The value of the asset type is optional, and the value is maintained by the super user;
● The value of the department used is optional, and the value is maintained by the super user;
● The value of the ownership relationship is (purchase|received|financing|rental|other);
● The production date is earlier than the opening time;
● It is stipulated that the useful life and the used life must be an integer greater than or equal to 0;
● The entered date format should be correct: such as 2017-01-01;
● The original amount and the installation cost must be in the correct format, accurate to 2 decimal places: 100.76;
● The depreciation rate must be in the correct format, accurate to 4 decimal places: 0.0932;
3.2.1.2 Delete asset information
Demand number: FR- ZCWH -2
Requirement description: Super users can delete asset information after logging in to the system.
The super user first finds the asset information that meets the conditions, then selects the asset to be deleted, and deletes the selected asset from the system. When the asset information is deleted, the related records corresponding to the asset will also be deleted.
