Guangzhou Tongwei Smart Technology Co., Ltd. (brand: Tongwei Smart)
Tongwei Smart
For equipment makers, cabinet builders and system integrators: industrial IoT gateways, expansion modules, and an operations platform that can run on-premise. We connect the protocols. We design the hardware.
We build the whole foundation of equipment connectivity — gateways, modules and the platform, every piece.
- Modbus RTU/TCP, SNMP, DL/T 645, IEC 104, S7, FINS and private protocols
- Gateways, DTUs and acquisition modules, available under your brand
- On-premise deployment; data stays on site
- Standard products in stock for small batches; white-label sample in 10 days
- The platform can be white-labeled, or we supply hardware only
Industrial-grade AIoT operations products and data services
Make equipment smarter, make operations simpler.
The problem
Connecting a device is easy. Keeping it running is not.
Tongwei does not simply sell sensors, gateways or dashboards. We connect scattered field assets, their data and the operations process around them.
- 01
Scattered sites
Equipment is deployed across regions and customers, so running status and fault information cannot be seen in one place.
- 02
Heterogeneous equipment
Controllers, meters and sensors span many brands and protocols, so onboarding work is repeated at high cost.
- 03
Late detection
Relying on customer reports or manual rounds means faults surface slowly, with little evidence for remote judgement.
- 04
Broken process
Alarms, dispatch, handling, feedback and reporting are fragmented, so ownership and service outcomes cannot be reviewed.
The result: more site visits, higher service cost, larger fault losses, and operating data that never accumulates into a data asset.
Where it stalls
Four places equipment connectivity stalls
You can fix just one of them. Protocol, hardware and platform can each be taken on their own.
- 01
The protocol will not connect
Legacy machines, mixed brands, private protocols — several suppliers have already said they cannot connect them.
- 02
No hardware to start from
Off-the-shelf gateways cannot be changed. Building your own means tooling, certification and a production line.
- 03
The platform never gets built
An in-house team is expensive. A public cloud is refused once data must stay on site.
- 04
Outsourcing feels unsafe
The fear is that a supplier learns the product and sells it, or disappears halfway through.
The boundary for this one is on the cooperation page.
How we take it on
Protocol, hardware and platform — we can take the whole chain
We build the base of equipment connectivity: all three. Protocol work can extend into hardware, and hardware into a platform in your own server room. If you only need one layer, that is all we deliver.
- 01
We connect the protocol
Start with the protocol document and the point table. If we have not connected it before, we read those and then say whether we can.
- 02
We design the hardware
Gateways and modules ship by model, or we adapt the enclosure and interfaces to yours.
- 03
We deliver the platform
It can run on your own servers, under your own domain. Data stays on site.
- Protocols are assessed item by item from the point table. We do not dodge, we do not exaggerate, and we assess with delivery as the goal. We do not promise work outside what we can actually do.
- Gateways, modules and terminals are long-term standard products by model. If a model does not meet the function or the requirement, we can discuss a custom design in depth.
- We deliver the solution package. You handle the commercial side.
- Strong software and hardware delivery. Projects are not subcontracted; our own team delivers them.
How it runs
Six steps that turn data into handled exceptions
Monitoring alone leaves exceptions seen but unhandled. These six steps are what makes the difference between a dashboard and an operation.
- 01
Connect
Onboard devices and data into one system.
- 02
Monitor
Uptime, state and trends made visible.
- 03
Alarm
Tiered, de-duplicated, routed to a named owner.
- 04
Diagnose
Inspect data and fault codes remotely.
- 05
Act
Remote coordination, dispatch and inspection.
- 06
Review
Logged feedback, reporting and optimisation.
- Anomalies follow rules
- Ownership is assigned
- Handling is recorded
- Results are reported
- Experience is reusable
Products
Products, by their role in the loop
Every product description states what it does in the loop, not just its specification.
Edge
Edge Gateways
Handle multi-protocol onboarding, protocol conversion, data aggregation, offline buffering, local interlocks and remote communication.
Sense
Expansion and Sensing
Turn field conditions into data and actions that can be captured, judged and acted upon.
Platform
Platform and Applications
Cover asset ledgers, data governance, alarms, work orders, inspection, permissions, reporting and mobile collaboration.
Ops
Alarm and Operations Terminals
Get alarms to people, then dispatch, feedback, closure and review.
Where it runs
In these industries, we have taken on the hardest protocols
Scenarios are evidence that the foundation adapts, not separate business lines competing for position.
Industrial Equipment Connectivity
Takes equipment makers and shop floors from data collection to remote service, full lifecycle management and continuous operations.
Legacy machines, control cabinets, shop floors, asset tags and equipment makers' products.
Power and Environment Monitoring
Unified monitoring of temperature, humidity, leaks, smoke, access control, UPS and switchgear so risks are found and handled in time.
Telecom rooms, data centres, integrated cabinets, substations and plant rooms.
Energy Efficiency and Carbon Accounting
See how energy is used, manage abnormal consumption, and turn sub-metered data into a usable base for carbon accounting.
Parks, buildings, public facilities, enterprise sites and PV/storage/charging stations.
Smart Restroom
Environment, occupancy, consumables and facility status become visible, with traceable cleaning and exception handling.
Public restrooms, hub and venue restrooms, and restrooms in commercial complexes.
Park and Building Operations
Brings lighting, HVAC, water systems and common-area equipment in parks and buildings into one monitoring and interlock view.
Offices, public buildings, park common areas and commercial sites.
Agriculture and Aquaculture
Fish ponds can be managed from home: switch aerators by phone, get a call on power loss, and protect the aerator. Greenhouses cover air, soil and irrigation, and production data accumulates.
Greenhouses, growing bases, fish ponds and modern fishery parks.
Smart Forestry
Unified monitoring of weather, fire risk, soil and boundary posts, with traceable patrols and exception handling.
Forest farms, ranger stations, boundary posts and field monitoring points.
Capability roadmap
Five levels, and where we actually are
L1 to L3 are what we promote today, along with selected verifiable L4 modules. We do not present predictive maintenance or autonomous operations as off-the-shelf features.
- L1 Available now
Visual monitoring
See the state of equipment, environment, energy and people.
- L2 Available now
Proactive alarms
Notify proactively on thresholds, loss of contact, state and trend.
- L3 Available now
Closed-loop operations
Alarms reach people; dispatch, handling, feedback and statistics are traceable.
- L4 Selected modules
Intelligent optimisation
Suggest maintenance, efficiency and scheduling actions from historical data.
- L5
Bounded autonomous operations
Execute and optimise automatically within explicit safety boundaries.
How we engage
Assess, validate, then scale
Diagnosis, sample, single-site pilot, then copy. Samples are chargeable in principle.
- 01
Diagnosis
Confirm equipment, protocols, sites, the pain, network and acceptance goals.
- 02
Selection / sample
Limit the devices and functions, then prove onboarding, alarms and pages. Samples are chargeable in principle, with credit possible against volume orders.
- 03
Single-site pilot
Produce the configuration list, rules, work orders, reports and service boundary as a repeatable acceptance sample.
- 04
Volume copy
Lock templates, an implementation handbook, pricing and the ongoing-operations mechanism, then copy to more devices or sites.
