Task Scheduling

Task scheduling is like traffic control. It is an important part of effectively controlling the order of networked devices, especially in the scenario of low power consumption and massive networked devices.
It can use the operator's network resources and the computing/storage resources of the server in a balanced manner, and achieve a relatively high quality of service without increasing the investment in the construction of the Internet of Things.

Group tasks

• A single task channel is mounted on the Group for engineering-level task scheduling and data aggregation,
• The channel automatically searches the object model of the multi-level sub-device to create an engineering-level instruction set. The size of the instruction collection for a single task process is currently limited to 2048
• Mainly used in smart home linkage, base station area centralized reading, OPC server, large warehouse equipment status inspection, etc.

Gateway Tasks

• A single task channel is mounted on GateWay for gateway-level task scheduling and data aggregation,
• The channel automatically searches the object model of multi-level sub-devices to create a gateway-level instruction set, and the size of the instruction collection for a single task process is limited to within 2048
• Mainly used in Modbus gateway, PLC gateway, DTU gateway, traditional concentrator, acquisition box, etc.

Multi-channel tasks

• Multiple task channels are mounted on multiple Groups or GateWays for multi-channel task linkage and data aggregation
• Create a device-level instruction set by automatically searching for a multi-level sub-equipment model, and the size of the instruction collection for a single task process is limited to 2048
• It is mainly used in scenarios where multi-channel acquisition is used to achieve equipment acquisition success rate requirements of close to 100%, such as the State Grid Southern Power Grid power acquisition success rate requirements of more than 98%

System Capacity

• The low-profile stand-alone server supports 100,000-level device data collection, command scheduling, task scheduling and data aggregation
• The single-server server supports millions of equipment data collection instructions, task scheduling and data aggregation
• The high-end stand-alone server supports tens of millions of equipment data collection instructions, task scheduling and data aggregation
• The high-end cluster server supports hundreds of millions of equipment data collection instructions, task scheduling and data aggregation
