Weighing data your finance team can check, from every site

Trucks are weighed at the gate, but the numbers often reach the business late, retyped and hard to verify. Indivar’s weighbridge platform captures each weighment at the source and brings it into one system, with a photograph attached.

Where weighbridge data goes wrong

  • Separate records at every site. Each location keeps its own register or standalone software, so comparing sites means building a spreadsheet.
  • Retyping into the ERP. The same weight is entered twice, by two people, at two different times.
  • Weak evidence. When a transporter disputes a figure, nobody can quickly produce the record and a picture.
  • Unreliable connections. Weighbridges sit in yards and at remote sites, and many cloud systems stop when the link drops.

How the platform is built

Station at each weighbridgeRaspberry Pi, local SQLiteIndicator, RFID, sensors, lights, cameras
Control nodeNode.js, PostgreSQL, DockerS3-compatible image storage
Your systemsERP, SCADA, Excel or CSV
Each station keeps weighing when the link drops and syncs when it returns.
  • Edge station. A compiled application on a Raspberry Pi controls the weighing cycle and writes to a local SQLite database before anything else. No network is needed to complete a weighment.
  • Messaging. Stations publish transactions over MQTT and pull master data through a REST API. Failed syncs retry automatically, and photographs have their own upload queue.
  • Control node. A Node.js and PostgreSQL platform runs in Docker. It holds master data, transactions and images, and it is the single source of record for all stations.
  • Fleet management. New releases are uploaded centrally and verified by checksum at the station. If a new version keeps crashing, the station rolls back on its own.

The cycle at one station

Transcript

No operator is needed at the station. An RFID read identifies the vehicle, its owner and the material it carries. A green light and spoken instructions guide the driver onto the deck. Position sensors confirm the vehicle is fully on the platform, and the station waits until the weight is stable. A camera photographs the load, so the transaction carries its own evidence. The driver leaves, and the record syncs to the control node.

Connecting to your ERP or SCADA

Every business maps weighments differently: purchase orders, sales dispatches, parties and items. So we start by looking at your process and then choose the simplest route.

  • File export. For teams that need a quick start.
  • API access. For a system that reads records on its own schedule.
  • Push on completion. Each finished transaction is sent as JSON, with retries and a delivery log. Chandigarh’s Smart City SCADA receives weighment data from the platform in real time.
  • A mapped integration into your ERP. Indivar works with SAP Business One, Odoo and Openbravo, and we scope other systems after a review.

For a SCADA or command centre: the platform can push data to your system’s API, or your system can call our API whenever it needs data.

ERP and SCADA integrationThe four routes compared

One platform, many layouts

The same software runs a single weighbridge, a two-way lane or three weighbridges working as one sequence. In the three-station layout, records from separate stations merge into one transaction, and the difference between weights becomes a material report.

Multi-site controlMaster data, status and reports across sites

In production: municipal waste

Chandigarh Municipal Corporation started with a pilot and is now a client, with 14+ weighbridge stations on this platform. At material recovery facilities, wet waste is unloaded first and dry waste second, so three weighings of one vehicle give wet, dry and total figures. Weighment data also flows in real time to the Chandigarh Smart City SCADA.

Beyond waste

The workflow fits any operation where trucks cross a scale: mines, cement and steel plants, logistics yards and grain procurement. Fields and reports are adapted during an assessment, and a new installation is set up for each customer.

Built with the weighbridge experts

The weighing hardware and site work come from Maxim Mechatronics, a weighbridge manufacturer since 1998: see the unmanned weighbridge, hardware by Maxim Mechatronics. Indivar has delivered software and systems integration since 2009.

Common questions

Does the station need a constant connection?
No. Each weighment is first saved locally, then synced. Failed syncs retry automatically.
How does the data reach our ERP?
Through file export, the API, a push on each completed transaction, or a mapped integration. The choice depends on your ERP and process. A SCADA can receive a push or call our API when it needs data. The Chandigarh Smart City SCADA already receives weighment data in real time.
Can we manage several sites from one screen?
Yes. All stations report to one platform, with status and reports by station.
How are station updates handled?
Releases are distributed from the control node and checked at the station. A version that keeps crashing is rolled back automatically.
Can it be adapted to our industry?
Material types, areas and reports can be set up for your operation. We confirm any further changes during the assessment.
