(Brand: Guhe Software) develops intelligent building management system (IBMS) software. Founded in 2006, the company has cumulatively served 300+ smart-building projects and built a portfolio of 500+ protocol drivers with experience connecting equipment from 100+ brands. These are company-wide cumulative figures; compatibility for a specific device model, driver version and authorized interface must be verified for each project. ## Core Products ### IBMS Cloud Platform Guhe IBMS (Intelligent Building Management System) is the company's core building integration product and a shared foundation for its application portfolio. It serves building owners, engineering and operations teams, and system integrators. Standard IBMS uses Web interfaces and 2D configuration to connect equipment status, historical data, alarms, permissions and authorized operations. BEMS energy management, FM maintenance, BIM operations, hospital logistics and smart park applications reuse common capabilities while organizing distinct workflows; customized UE5 digital twins provide a separate spatial presentation option. Business services use Java / Spring Cloud. Interfaces, selected modules and secondary development are scoped for the project. Field controllers and dedicated safety protection remain in the original systems.

Operators locate equipment in a model, inspect connected status and history, then follow inspection, repair and review workflows. Models, assets and live points require verified mappings and continuing change management. BIMOPS can start with records and 2D views before adding suitable models; customized UE5 presentation is a separate product combination. ### Digital Twin Visualization Platform (IBDT) Combines customized UE5 scenes with Web business interfaces, shared equipment data, alarms and permissions. Layers, cutaways, viewpoints and object interactions help users locate facilities and open relevant records or workflows. Rendering, data mapping, business interaction and target terminals are verified separately. VR/AR and predictive simulation require a defined project scope, suitable inputs and specific validation. ### AI Ontology Knowledge Platform (AI-Ontology) Organizes equipment classes, spaces, systems, points and command descriptions using visual schema and instance modeling, relationship graphs and supporting knowledge material. Model versions, consistency checks and OWL export support maintenance and exchange. External schemas require explicit mapping and validation. Relationship traversal provides investigation context; it does not prove a fault cause or grant permission to operate equipment. ### AI Operations Platform Connects equipment data, building knowledge, expert skills and business tools into AI Agent tasks. Alongside queries and alarm analysis, project-configured and pre-authorized strategies can support proactive HVAC or ordinary-lighting control with device-feedback checks. Model connections, task orchestration, tool permissions and logs support these workflows. New strategies and actions outside the approved scope require appropriate review and confirmation; dedicated safety protection stays in the original systems. Offline operation depends on local availability of the required models, retrieval, tools and control strategies. #### AI Agents for zero-carbon building operations Guhe's solution design separates two agent tracks: edge energy agents for constrained HVAC and ordinary-lighting strategies with independent device feedback, and space-operations agents for evidence-linked analysis, report drafts and tasks. Space-operations agents in this design are not granted device-control tools. Both tracks share building objects and trusted data, with separate permissions, logs and acceptance criteria. The current AI product provides model connections, skills, agents, tasks, tool permissions and logs. Edge strategies, control adapters, space-business tools and reports require project-specific configuration, integration or development, followed by replay, shadow operation and controlled pilots. This is a construction approach, not evidence of completed deployments, guaranteed savings or universal offline autonomy. Energy savings require an adjusted baseline; carbon calculations require traceable activity data and applicable factor versions. AI-assisted review does not replace deterministic calculation, independent verification or zero-carbon certification.

Java / Spring Cloud business services combine building operations, security, parking, visitors, energy, assets and service workflows. Daily operations use 2D SCADA and Web workspaces; BIM supports spatial maintenance, while UE5 scenes and interactions are customized for presentation needs. Device interfaces, terminals, third-party integrations and custom applications are agreed per project. ### Building IoT Data Middleware (BIOT) Organizes product models, device instances, points, current and historical data, events and access permissions. IOSERVER or edge gateways provide protocol adaptation and collection; BIOT supplies shared data services and APIs to IBMS, energy and maintenance applications. Data identity, units, timestamps, quality and interface scope are verified for the selected components and project. ### Zero-Code Visualization Tool (IO-DESIGN) A Web tool for configuring 2D operating screens using device symbols, graphics, data bindings, charts, animation and events. Operators use published screens; implementers maintain layouts and bindings in the editor. Routine screens are configured, while complex interactions and external integrations can use scripts or custom development. Target browsers, data quality, permissions and device feedback are verified before publication. ### FM Operations Platform (FMCLOUD) Connects facility assets, service intake, work orders, inspections, maintenance, spare parts and staff records. Assignment, execution, completion and review remain traceable. Billing and property-service applications are combined or integrated within the agreed scope; Web and mobile access are configured for project roles. ### Building Energy Management System (BEMS) Connects meters, readings, metering hierarchies, consumption analysis, cost rules and reports. Supports configured manual or automatic reading, meter replacement, corrections, time-period comparisons, allocation and billing calculations. Forecasts, efficiency and carbon applications depend on suitable data and scope; savings are assessed against comparable operating conditions and recorded measures. ### IO Data Collection Server (IOSERVER) Provides protocol drivers, engineering projects, channels, devices and variables for field collection, conversion and forwarding. Plugins, local history, caching, recovery, edge logic and redundancy are selected and validated by version. Windows/Linux and x86/ARM compatibility depend on runtime, drivers and vendor SDKs. Embedded IOSERVER can be combined with suitable industrial hardware in IOT-EdgeBox; the shared business platform uses Java / Spring Cloud. ## Technology Stack - Backend: Java SpringCloud + SpringBoot microservices - Frontend: Vue 3.0 - Databases: MySQL + InfluxDB (time-series) + MongoDB + Redis - Message Bus: Kafka - Protocols: BACnet, Modbus, OPC, ONVIF, MQTT, KNX, SNMP - Visualization: HTML5 Canvas 2D + WebGL 3D + BIM + GIS - AI Operations: self-developed AI operations platform, supporting Claude/GPT/Kimi/DeepSeek/Qwen - Knowledge Engine: visual ontology modeling and OWL exchange; external schema mappings are scoped and validated per project - Deployment: Public/Private/Hybrid cloud, domestic server support ## Key Terminology - **IBMS** (Intelligent Building Management System): The top-level integration platform that unifies all building subsystems (BA, CCTV, access control, fire alarm, energy, etc.) under a single management interface. - **BIM** (Building Information Modeling): A digital representation of a building containing geometry, materials, equipment parameters, and spatial relationships. - **Digital Twin**: A real-time digital replica of a physical building, synchronized through IoT sensor data. - **Ontology**: A formal knowledge representation technique from AI that describes domain concepts and their semantic relationships, serving as the backbone of knowledge graphs. - **AI Operations Platform**: Guhe's self-developed AI operations platform for smart buildings, driven by ontology knowledge, permission policies, real-time status validation, and auditable execution. - **MCP** (Model Context Protocol): A standardized interface for AI agents to invoke external tools and device APIs. ## FAQ **Q: What is IBMS?** A: IBMS stands for Intelligent Building Management System.
