Problems solved by technology
However, since the ISA100.11a standard uses natural language descriptions and involves many key technologies, designers' different understanding of the protocol will lead to different protocol implementations, and sometimes even wrong implementations
The physical layer communication of this standard adopts IEEE 802.15.4 protocol, multi-channel frequency hopping and deterministic time slot allocation mode, which is very difficult in the process of equipment debugging, especially in the process of interconnection between different manufacturers. Different handling of details makes it difficult for devices from different manufacturers to run in a network

Embodiment Construction
[0024] Taking a time slot channel monitoring and verification system based on IAS100.11a standard as an example, the present invention is introduced in detail.
[0025] Initialization process:
[0026] Such as figure 1 As shown, the monitoring and verification system based on the ISA100.11a standard has 16 channels, C1...C16, and can monitor 16 channels at the same time. Each channel uses a set of receiving devices, and each receiving device leads to a receiving device. The indication signal is used as a real-time indication signal for receiving frames. The channel monitoring system is initialized, the channel is configured and started for each channel receiving device respectively, and the data frame of each channel is started to be received. figure 1 The dashed box in the middle is the monitored ISA100.11a wireless network system.
[0027] working process:
[0028] During the monitoring process, when the monitoring module of 16 channels receives the frame, it will indica...

The invention provides a timeslot signal skip monitoring verification method conforming to the ISA100.11a standard. The method includes: configuring a wireless channel monitoring module and a logical analysis module; linking a timeslot indication signal of backbone router equipment to the logical analysis module; linking a receiving indication signal of the wireless channel monitoring module to the logical analysis module; starting the logical analysis module and the wireless channel monitoring module; operating the backbone router equipment prior to operating terminal equipment. By adoption of the method, debug time can be greatly saved, problems in interoperability test with products of other manufacturers can be effectively positioned, development cycle is greatly shortened while personnel cost is greatly saved, and product interoperability is improved.
Description
technical field [0001] The invention relates to a time slot signal hop monitoring verification method conforming to the ISA100.11a standard, which belongs to the technical field of wireless communication. Background technique [0002] During the development of wireless sensor network (WSN), the ISA100.11a standard formulated by the ISA100.11a industrial wireless committee under the International Society of Automation (ISA) mainly includes industrial wireless network architecture, coexistence, robustness, Interoperability with wired field networks, etc. The ISA100.11a standard expects industrial wireless devices to support industrial field applications with low complexity, reasonable cost, low power consumption, and appropriate communication data rate. [0003] The ISA100.11a standard will soon become one of the most concerned and influential industrial wireless technologies, and the research and development work on the ISA100.11a technology is in full swing. In addition, t...
