Anti-corrosion of landfill scale: Unmanned weighing system enhances the efficiency of environmental sanitation

I. Case Background: Pain Points of Traditional Weighing and the Demand for Intelligent Transformation
 

The waste treatment scenarios of large-scale chemical enterprises have long been confronted with three major challenges: the corrosive environment shortens the service life of equipment, manual weighing is inefficient, and the risk of data tampering is high. Taking the garbage treatment station in a certain chemical industrial park as an example, the average service life of traditional weighbridges in acid mist and salt spray environments is less than two years.

Drivers need to get off the vehicle to register, and the weighbridge operators manually enter the information. The time spent on a single vehicle trip exceeds 10 minutes, and during peak hours, it causes traffic congestion of over 2 kilometers on the factory roads. In 2025, the audit found that due to vulnerabilities such as remote control cheating and manual data tampering, the annual loss exceeded 4 million yuan.

With the implementation of the "Intelligent Management Specification for Hazardous Waste Treatment", enterprises urgently need a set of landfill scale solutions that are suitable for corrosive environments and support full-process automation. WEITEWOSI(WEIGHTWORTH) truck scales, with their "anti-corrosion design + unmanned operation" technology, have become the core choice for the digital transformation of waste treatment in chemical enterprises.

III. Implementation Process: Phased deployment and rapid implementation
 

1. Requirements analysis stage: The WEITEWOSI(WEIGHTWORTH) team will complete the on-site investigation within two weeks, customize the anti-corrosion solution and anti-cheating strategy.
2. Hardware renovation stage: Adopt modular design to complete the upgrade of the weighbridge sensor and the installation of the sealed control cabinet within 5 days, avoiding production halts that could affect operations.
3. Software debugging stage: Through pressure tests, a weighing scenario of 2,000 vehicles per day was simulated, and the license plate recognition algorithm was optimized, with the accuracy rate increased to 99.9%.
4. Training stage: Conduct stratified training for drivers and operation and maintenance personnel, and achieve independent operation for all staff within two weeks.

Iv. Implementation Effect: Dual improvement in efficiency and compliance
 

1.Efficiency breakthrough: The time for a single vehicle to be weighed has been reduced from 10 minutes to 12 seconds, and the number of vehicles processed per day has increased from 150 to 1,200, with a 75% improvement in weighing efficiency.
 

2. Cost optimization: Reduce the number of weighers by 8, saving 1.2 million yuan in labor costs annually. The extension of equipment lifespan reduces maintenance costs by 40%.
 

3. Risk Management and Control: The anti-cheating system intercepted abnormal data 89 times, recovering losses of over 3 million yuan annually. The data tampering incident is reset to zero.
 

4. Management Upgrade: Real-time summary of data from multiple factories, the generation time of headquarters reports has been reduced from 3 days to 1 hour, and decision-making efficiency has been increased by 80%.
