Plant Intelligent Logistics Management System

Project Overview

XY-TMS applies industrial IoT and big-data technology to in-plant logistics. Around the XY-TMS platform it brings together ticket verification and queue calling, access control, safety inspection, unattended weighing and loading/unloading control, and exchanges data with ERP and DCS in real time — integrating depot and plant storage, field systems and equipment into one live management system with standardised workflows and automated processes. Drivers book remotely from the cloud, verify documents and take a queue number themselves, weigh in unattended, run intelligent loading and unloading, pass automated entry and exit checks, and have safety and business reports generated for them. Manual intervention across the loading cycle drops, throughput and service quality rise, physical workload falls, the site gets safer and the business more profitable. Management, meanwhile, gets reliable, accurate and consistent operating data — the basis of an efficient, low-carbon, safe and transparent smart warehouse or plant.
Overall Design Objectives

Overall Design Objectives

Intelligent Management
Remote booking for site visits, self-service registration and queue calling, smart queuing outside the gate, safety inspection on tanker entry, SOP guidance, automatic recognition at entry and exit gates, self-service weighing, automatic bay allocation, and automated loading control with safety interlocks.
Technical Innovation
Advanced, reliable and highly extensible, integrating seamlessly with the company ERP and DCS. Equipment and databases scale with the business.
Safe and Dependable
Entry safety checks, SOP work guidance and equipment interlocks run through the whole process, fixing safety requirements into every operational step.
Shared Data, Converged Applications
Connected smart equipment and integrated technology work alongside ERP and DCS, sharing and converging data with upstream and downstream systems for intelligent management of the full tanker loading and unloading cycle.
Friendly Interface, Simple Operation
A friendly human-machine interface that is simple to operate and easy to adopt, asking as little as possible of field operators.

Platform Hardware and Performance

XY242 Explosion-Proof Batch Controller

The XY242 pairs a Siemens PLC with an explosion-proof keypad terminal. Together with standard supervisory software and advanced control algorithms it delivers high control accuracy, dependable performance and easy maintenance. Its communication protocol is fully open for integration with customer management systems, and it works with flow meters, thermometers, level switches, earthing switches, control valves and supervisory computers to form a complete distributed batch loading and unloading control system.

System Benefits

System Benefits

01
Stops fraud, closes gaps, prevents loading errors
Saves RMB 0.5–5 million per weighbridge each year and removes the safety risk of loading the wrong tank.
02
Faster logistics and tank storage
5–15 seconds per vehicle — ten times the weighing throughput.
03
Process design that keeps every step safe
Online training and safety assessment; intelligent guidance and safety checks; equipment interlocks and protection.
04
Fewer staff,
more output
80% fewer weighing staff, with lower labour and management costs.
05
Mobile app
Delivery booking, online assessment, delivery-note review and safety inspection.
06
Interfaces across systems
Integrates with ERP (SAP, Kingdee, Yonyou), LIMS and DCS.

Case Studies

  • CNOOC Huizhou Petrochemical — XY-TMS Intelligent Storage and Loading Management
    Unit 228 at CNOOC Huizhou Petrochemical deployed XY-TMS to replace manual ticketing, repetitive vehicle checks and risky document verification. The system supports online booking and registration, self-service ticketing and settlement at kiosks, unattended weighing and end-to-end loading supervision, making the whole flow self-service. During trial operation it handled over 5,500 vehicle movements and more than 145,000 tonnes of product, saving over RMB 2 million a year in operating costs and closing the loop on digital loading control across the depot.
