Such as: query by vehicle number, query by shift, query by shipping unit, query by time, etc., and can query by combination of conditions. The system can print daily reports, monthly reports and other reports (multiple report formats), and can also print according to the query results, and can make personalized reports according to customer requirements.
(10) Network weighing of multiple truck scales
The system can realize networked weighing of multiple truck scales. The same vehicle can be tare and gross weight on different truck scales. Each weighing data is updated in real time, which effectively improves the utilization rate of truck scales. The system can automatically generate EXCEL reports from the measurement data according to needs, and automatically transmit them to the computer of the designated department via the network.
Second, the unattended weighing management system of the platform scale
For a long time, electronic weighing instruments have been widely used in the bulk material industry. However, these electronic measurement equipment have been stuck at the level of auxiliary manual measurement, manual reading, and re-summarization by special personnel, which seriously lags behind the overall information management process of the enterprise.
Under manual recording and measurement, how to effectively monitor the entire measurement process, prevent fraudulent behaviors, and improve application and management efficiency has become a matter of great concern to business leaders. Some companies frequently replace weighing officers, setting up weighing supervisors, and The installation of electronic monitoring equipment and other methods to monitor the measurement process, but can not fundamentally eliminate fraud. The functional requirements for weighing room management of unattended weighing software for platform scales mainly include functional groups such as automatic reading, video monitoring, data monitoring, infrared monitoring, credit card management, language command management, signal control management, special processing, and real-time query.
1. The business process description of unattended weighing software for platform scales
1. The company’s guard office deploys a computer that is responsible for the issuance and recovery of IC cards. The client can register basic vehicle information. Before non-fixed vehicles enter the factory, the basic information of the vehicle must be registered, such as: supplier, driver, Drivers, product names, and other information, and then the bridgehead staff will issue RFID cards (electronic tags) that can enter the factory to the vehicle drivers, and the drivers can weigh in only after receiving the cards.
2. Before the vehicle arrives on the weighbridge, it must be weighed on the scale according to the sequence of traffic lights.
(1) When the local scale has not been sorted, there are red lights on the sides of the vehicle. When the vehicle is swiped and verified successfully, the green light at the entrance is on, the voice prompts “Please load the scale successfully”, and the vehicle information corresponding to the IC card is displayed On the interface.
(2) After the vehicle is weighed, the front and rear lights are red.
(3) When the weight of the vehicle is stable, the weight data will be automatically saved, and the voice prompt “how many tons of weight this time, please weigh down”, the exit is a green light.
(4) After the vehicle is weighed down, the front and rear lights are red, and the weighing is completed.
3. After the incoming vehicles are unloaded according to the prompts, they need to go to the light weight to carry out the skinning operation.
When peeling back, the system will automatically determine whether the vehicle is over gross, whether it has been unloaded for acceptance and other information. If the vehicle does not complete the corresponding procedures as scheduled, the system prompts that the vehicle cannot be peeled back. If the vehicles have completed the corresponding procedures, the system automatically saves the vehicle. The tare weight information is used to generate a complete weighing list, which can be automatically printed in the light weight room, and the driver takes away a copy of the weighing list.
4. After the vehicle is weighed, the driver can deliver the RFID card (electronic tag) to the relevant staff in the guard room (or the driver may carry it by himself).
5. Unattended solution of platform scale unattended weighing software
1. The unattended weighing room management system mainly refers to the measurement and weighing performed by enterprises in the process of raw material procurement, product sales and in-plant material allocation. It can be used with RFID (non-contact radio frequency equipment) card swiping systems, video monitoring systems, and infrared monitoring systems. The language command system, LED display system, short message issuing system, and signal control system realize unattended management system. The system can automatically collect gross weight, tare weight information, vehicle weighing pictures, automatic net weight statistics, automatic printing, real-time monitoring of data and pictures through LAN and Internet connection, and the query of the scale can be associated with image information. Company leaders can inquire weighing data on any machine to strengthen the company’s internal management level.
6. Intelligent control system
Can be unattended. This software cooperates with the non-contact sensor swiping technology to realize unattended operation. When the car is parked on the weighing platform, the software automatically collects vehicle information through the swiping device. After the software judges that the weighing data is stable, it can capture the photo and save the gross weight or tare at the same time. Use a camera to take a picture of the driver when he swipes his card, then print the receipt, let the vehicle go, and then start the next vehicle. When a car comes to the tare for the second time, the software automatically calls up and collects the vehicle information. After the software determines that the vehicle is stable, it starts to capture the tare photos and saves the weight at the same time, and then combines the data with the first gross weight data into one Record, calculate the net weight, and then print the receipt. In this way, the gross weight, tare weight, net weight data of the vehicle and the photos when the gross weight and tare weight are saved are saved in the computer, as well as the driver’s card number, which corresponds to the vehicle number one by one. If the vehicle number and the card number on the photo are found to be inconsistent , And the driver’s photo is inconsistent, the driver is suspected of cheating, so the general driver dare not change the vehicle, to ensure that the weighing of the gross weight and the weighing of the tare are the same vehicle.
