Intelligent Upgrade of Hengyun Livestock Transport Compartments: IoT Gateway Device M300 Reshapes the Livestock Transportation Management and Control System

In the process of full-chain digital transformation in the modern livestock industry, the live transport of livestock and poultry, as a core link connecting breeding farms with slaughterhouses and sales channels, has long faced industry pain points such as uncontrolled environmental parameters, untraceable transportation status, and delayed emergency response.

Traditional livestock transport compartments have largely relied on manual inspection and post-event record supplementation. This management model not only makes it difficult to ensure the survival rate of livestock and poultry during transport but also fails to meet the regulatory requirements of the Ministry of Agriculture and Rural Affairs regarding traceability and animal epidemic prevention control for livestock transport.

With the deep penetration of edge computing technology into livestock scenarios, Hengyun livestock transport compartments, equipped with the high-performance IoT gateway device M300, have established a full-process intelligent management and control system based on "real-time perception – local decision-making – cloud collaboration," providing a reliable implementation path for cost reduction, efficiency improvement, and compliant management in the livestock transport segment.

The intelligent retrofit of Hengyun livestock transport compartments centers on four core requirements:

① Millisecond-level acquisition of environmental indicators inside the compartment, such as temperature and humidity, carbon dioxide concentration, and ammonia concentration, to avoid livestock stress deaths caused by localized environmental anomalies;

② Closed-loop coordinated control of on-board fans, ventilation windows, and temperature control systems, enabling rapid response to environmental changes without requiring cloud-based instructions;

③ Local storage and intermittent data transmission with resume capability for full-journey transport data, preventing data gaps caused by the absence of network signals in remote pastoral and agricultural areas;

④ Unified access for multi-protocol devices, ensuring compatibility with sensors, frequency converters, positioning terminals, and on-board monitoring cameras from different brands. These requirements place demands on the edge gateway's acquisition capabilities, computing performance, protocol compatibility, and industrial-grade reliability that are far higher than those of ordinary consumer-grade IoT devices.

Designed as a modular edge gateway specifically for complex industrial and agricultural scenarios, the M300 has demonstrated exceptionally strong scenario adaptability in the practical application of Hengyun livestock transport compartments.

At the data acquisition level, the gateway supports Modbus RTU/TCP, DLT645, and over a hundred mainstream PLC protocols including Siemens, Mitsubishi, and Inovance. It can directly connect to environmental sensors and control devices of different brands inside the compartment without requiring additional protocol converters, substantially reducing the retrofit cost of the on-board system. Equipped with a 1.2GHz dual-core Linux processor, the gateway supports parallel acquisition of up to 2,000 data points, simultaneously covering temperature, humidity, and air quality monitoring points across multiple zones within the compartment, with acquisition latency controlled at the millisecond level—fully meeting the high-density data acquisition requirements during livestock and poultry transport.

At the edge computing and local coordinated control level, the M300 incorporates a Node-RED graphical programming environment, allowing maintenance personnel to customize control logic within the compartment through drag-and-drop components without complex code development:

● When the ammonia concentration exceeds a preset threshold, the gateway can locally trigger the ventilation fans to operate at full speed directly;

● When the compartment temperature exceeds the safe range, it automatically coordinates with the temperature control system to adjust cooling/heating power. All control decisions are completed locally without waiting for cloud-based instructions, achieving a response speed improvement of over 90% compared to traditional cloud-based management and control modes.

This local closed-loop control capability completely resolves the issue of delayed control instructions caused by unstable network conditions during transport. According to actual project estimates, Hengyun livestock transport compartments equipped with the M300 have achieved a survival rate improvement of over 8% compared to traditional transport modes, reducing the loss from accidental livestock deaths per single trip by more than one thousand yuan.

In terms of network transmission and data reliability, the M300 supports parallel transmission across 4G/5G, WiFi, and Ethernet, with a proprietary link detection and automatic switching mechanism that enables seamless network link switching in pastoral and mountainous areas with fluctuating signal conditions, avoiding transmission interruptions. The gateway features 2GB of local storage and supports data continuation upon network recovery. When the vehicle travels through areas without public network coverage, all collected data can be fully stored locally and automatically retransmitted to the cloud server once the network is restored, ensuring complete data integrity throughout the entire transport process and fully meeting the compliance requirements of the livestock transport traceability system.

Additionally, the gateway integrates multiple VPN networking functions such as PPTP, L2TP, and OpenVPN, enabling secure remote access to the on-board control system by maintenance personnel. This allows remote debugging of control logic and firmware upgrades without requiring the vehicle to return to the depot, significantly reducing maintenance time and labor costs.

At the hardware expansion and industrial-grade protection level, the M300 host comes with 2 DI, 2 DO, and 2 AI interfaces, enabling direct connection to door status sensors, emergency alarm buttons, and other devices. Its modular expansion design supports up to 6 external I/O expansion modules, flexibly matching the interface expansion needs of livestock transport compartments of different tonnages without incurring additional costs for redundant interfaces.
The device itself has obtained multiple domestic and international authoritative certifications including 3C, ANATEL, CE, CTA, ECAS, ROHS, FCC, MTC, NBTC, RCM, SRRC type approval, TDRA, and WEEE, meeting the relevant requirements for network security standards. Its operating temperature range covers -25°C to 75°C, and it supports both DIN-rail and wall-mounting installation methods. The device can withstand harsh conditions during transport such as vibration, high temperature, and high humidity, with a mean time between failures (MTBF) in livestock transport scenarios far exceeding the industry average.

For livestock transport enterprises, intelligent system integrators, and other purchasers, choosing the M300 as the core management and control gateway for Hengyun livestock transport compartments not only provides an integrated "acquisition – computing – control – transmission" capability but also leverages the product's full certification credentials and long-term stable supply chain support to rapidly complete the deployment of intelligent solutions, establishing differentiated competitive advantages in the fiercely competitive livestock digital market.
