The pit-type scale realizes the automatic control of the on-site weighing device, making the weighing business processized and automated. It enables multiple on-site unmanned measurement methods and real-time data transmission through the data network for measurement. The entire weighing measurement process is remotely controlled (including resetting the instrument and resetting the equipment), without the need for personnel to operate on-site. The system is connected to the company's access control security system to achieve one-card functions for vehicle entry, loading and unloading weighing, and factory exit logistics management. In addition, the system is connected to the company's ERP system in real time to realize digital transmission and management of weighing measurement data, supporting the real-time cost and financial accounting of ERP, eliminating the need for complicated manual statistics of tickets, report preparation, and submission, and effectively supporting the company's overall informatization construction.

The scale has realized the factory internal network WEB release of the Measurement system and has implemented multi-angle query and autonomous generation of reports in the WEB system. Relevant production management and command departments and branches can query in real time. It realizes the real-time exchange of measurement data between the measurement department and the user department, as well as异地 measurement and weighing of materials. This reduces the number of measurement personnel and saves labor costs. It provides real-time measurement data for Jigang's procurement settlement and production management.

The Weighing system is equipped with a scale body system， on-site computer terminals， cameras， hard disk recorders， switches， serial port instruments， switch quantity instruments， on-site lighting， LED display dot matrix screens， infrared beam switches， vehicle number recognition devices， intercom systems， etc. The main functions of the on-site control device of the scale： to determine whether the truck is fully on the scale， to automatically read the vehicle number information， and to obtain weight data from the weighing instrument in real time through the RS485 protocol interface. To monitor the vehicle number， goods， weighing status， bill， and the safety environment on-site and indoors. Install a digital hard disk recorder to store the monitoring images of the scale room. Remote start the on-site computer， exchange data and control instructions through the interface protocol and the main control room， and simultaneously store and back up local data. It can communicate through intercom and the main control room， view the ticket sheet through the touch screen， and choose to print the weighing sheet as needed. Monitor the remaining paper and ink， and have alarm prompts. The weighing room supports remote system diagnosis and has functions such as automatic fault alarm， upload， and recording.

The business process of the scale part system starts with the department (supply， sales， branch) that needs to apply for the measurement business to propose a measurement application plan. In the company's ERP system， a measurement application plan sheet is formulated， including vehicle number， planned measurement time， planned measurement material name， material specification， shipping unit and receiving unit， etc. The measurement application plan sheet is sent to the automatic measurement system through the industrial Ethernet optical fiber network in the form of a message， and sent to the data exchange server. For vehicles entering the factory for delivery or transportation， before entering the factory， an RFID card will be made by the security guard. When making the card， the security guard will select the information from the ERP system that matches the current vehicle measurement application plan sheet based on the driver's business voucher， and match this measurement application plan sheet with the current RFID card， and stipulate that only the driver can drive the vehicle into the factory (to prevent someone from hiding in the vehicle to cheat during weighing). For internal transportation vehicles within the factory， each vehicle holds a fixed RFID card， and the vehicle executes a fixed long-term measurement application plan sheet. When there is a change， the planning department can modify it in the system.

When the vehicle is weighed on the scale, the infrared detection device at the scene checks whether the vehicle is fully on the scale. Once it confirms that the vehicle is fully on the scale, the voice system automatically prompts the driver to get out of the vehicle. The vehicle number identifier automatically identifies the RFID card held by the vehicle, and the automated measurement system automatically searches for the matching measurement application plan sheet in the system. The staff in the main control room monitor the license plate of the vehicle and whether the driver has gotten out through video surveillance, and after confirming that the vehicle number matches the plan sheet, they click the confirmation button in the operation interface. The weighing process ends, and the voice system automatically prompts the driver to get back in the vehicle and start the weighing process again. The weighing data is backed up and stored at the terminal in the scale room, and is automatically uploaded to the data server in the main control room for storage via the network. In case of any unexpected situations during the process, both parties can communicate with each other by calling each other through the intercom system. After the vehicle completes two weighings, the measurement system automatically generates complete measurement data and transmits it to the ERP system. In addition, the system also realizes the function of remote measurement. When unexpected situations such as faults, power outages, and network disconnections occur, with authorization, remote weighing can be performed.
