Chapter 1 Overview
This system organically combines the construction site transportation dump truck with the IC card for the metering and counting through the computer, and realizes the automatic management of the smart card. Users use smart cards to measure and form a revenue and expenditure management system. The system avoids all the drawbacks of collecting money in the process of income and expenditure, and at the same time can increase the transaction speed several times. After consumption, the computer can immediately summarize, count, and print reports for various consumption, which is convenient for the department to carry out cost accounting. The use of smart card management system greatly improves the modern management methods and corporate image.
Chapter 2 Analysis of the demand for the use of hand-held machines with IC cards for measurement and counting of dump trucks on construction sites
1. System technical requirements (design and acceptance criteria):
Because there is no electricity on the construction site, it is necessary to count the number of transport dump trucks, use the handheld to give the supervisor on duty to manage the number of vehicle transports, and then export the data for statistics.
specific sitiuation:
1. There are a number of vehicles of different sizes and tonnages
2. Vehicles are filled with soil from several earth loading stations (such as WK600, WK700, WK800 stations), and unloaded at filling stations (such as TK600, TK700, TK800 stations) or spoil stations (such as QK600, QK700, QK800 stations) .
3. IC cards are required to identify the identities of vehicles of different sizes and tonnages (one vehicle, one card), and the vehicle will swipe the card once at the loading site (such as WK600, WK700, WK800 sites), the handset will beep once, and the display screen will display: ” The card is successfully swiped”, the handheld device reads the card information: license plate number, vehicle tonnage, and at the same time writes the starting point and loading time into the card, and saves all the above information in the handheld device to generate a record, the car filled with soil Swipe the card once at the filling site (such as TK600, TK700, TK800 site) or spoil site (such as QK600, QK700, QK800 site), then the handheld device will read the card information: license plate number, vehicle tonnage, and read at the same time Take the soil loading site (such as WK600, WK700, WK800 site) and loading time written into the card just now at the starting point, and automatically call the unit price between each pair of sites preset by the handheld and the computer system, and print the small ticket: small The ticket shows the license plate number, loading site, loading time, filling site (or spoiling site), filling time (or spoiling time), unit price (amount), handheld operator number, name, and reserved driver’s signature Spaces. The card will clear this record and prepare for the next record cycle, and the handheld will generate a record.
4. The query requirements of the computer software system are based on the following keywords:
A. Borrowing site
B. Filling site
C. Spoil site
D. License plate number
E. Date
F. Unit price
G. Driver’s name
Note: Simple operation required:
A. You can drive printing by swiping the card.
B. Two small tickets can be printed at the same time, one is given to the driver and the other is archived.
C. Every day or every once in a while, the company sends an administrator to the construction site with a laptop to collect data from the handheld after get off work.
D. Even if the card can be swiped normally at the loading point, the card is damaged during transportation and the card cannot be swiped at the unloading station, the driver can apply for a card replacement. And apply to the management center in writing to make up the data of the unloading point.
E. The computer software system and the software system on the handheld machine can be set: site name/unit price/according to the input distance (km)/automatically calculate the amount.
F. The unit price between each pair of sites will change due to the change of date.
2. User demand analysis:
1. Use several handsets with receipt printing and IC card swiping functions at the construction site.
2. Establish a management center in the company office, which is mainly responsible for card management, card issuance, card cancellation, and card swiping data collection for the transport dump truck drivers and management personnel cardholders. Print out the total report and the statistical report of each driver according to the card data collection every month;
3. The driver uses the card to calculate the distance/count/measure (tonnage) at the loading station and the unloading station to settle the price.
4. The front of the consumer card is marked with company name, card number and other information; the back is marked with precautions.
Chapter III Design Basis
The design standards and specifications involved in the system design mainly include:
“Smart Building Design Standard (DBJ08-47-95)”
“Commercial Building Cable Standard (EIA/TIA-569)”
“Industrial TV System Engineering Design Specification (GBJ115-87)”
“Code for Construction and Acceptance of Electrical Installation Engineering (GBJ23-90, 92)”
“Safety protection engineering procedures and requirements (GA/T75-94)”
Chapter 4 Solution
According to a detailed analysis of customer needs, it is planned to use a hand-held machine with receipt printing and non-contact IC card swiping functions on the construction site, and a special system for collecting data from the hand-held machine in the office for report statistics, output and printing. The specific solutions are as follows:
1. Install a computer server in the office management center, and install special newly developed software on the server to receive and manage the swiping data software collected from the handheld; at the same time, install a card issuing machine to authenticate the card.
2. The driver uses the card to calculate the distance/count/measure (tonnage) at the loading station and the unloading station respectively to settle the price.
3. Card issuance: A non-contact IC card is used for unified card issuance to drivers and administrators.
4. Handheld operation administrator: The cardholder is authorized to operate the handheld with a valid card authorized by the card issuance;
V. Output: At the end of the month, the office management center will output the total expenditure table based on the collected data of each handheld, as well as the tonnage of each driver’s transportation vehicle and the income sub-table, and the report of each manager’s work situation;
6. Card replacement: If the cardholder loses his card, he must apply for the card supplement through the office management center;
7. Receiving the card: If the driver or employee resigns, they can take back the IC card and return the deposit with the certificate issued by the office management center;
