Description

technical field [0001] The invention relates to the technical field of information collection, in particular to a sensor general interface and an information collection system for the sensor general interface. Background technique [0002] At present, in the field of ocean observation, in order to meet the strong demand for space and time in ocean research, development, and utilization, it is an inevitable development trend to build an ocean observation system that can comprehensively, coordinate, real-time, and continuously obtain various ocean physical parameters. . In the ocean observation system, in order to obtain various physical parameters, the early observations used manual measurement to judge environmental information based on personal experience. With the development of electronic technology, storage-type environmental monitoring equipment has emerged, which can periodically retrieve data for analysis, such as various sensors, which can monitor various informatio...

AI Technical Summary

Problems solved by technology

The incompatibility between different types of sensor interfaces and the variety of protocol formats, on the one hand, easily lead to complex and confusing field wiring, which greatly increases the amount of engineering tasks

On the other hand, system maintenance requires manual installation and configuration by technicians, and the harsh working environment at sea increases the possibility of human error, which brings a lot of inconvenience to the construction, expansion, update and maintenance of marine observation systems.

[0004] In order to be able to connect different sensors at the same time, the industry has also made relevant efforts. A universal sensor interface UTI03 interface chip has been launched on the market, which is an interface chip developed for resistive, microcapacitive, and resistive bridge sensors. Requires complex hardware circuits to implement

Although it can solve the problem of compatibility of limited types of sensors to a certain extent, due to the relatively single type, the connection of sensors is also very complicated, the requirements for specific sensor interfaces are also high, and even customization is required. The types of sensors are difficult to tailor, so there are still The shortcomings of insufficient generalization ability, insufficient interface types, and limited data interaction speed still cannot fundamentally solve the problem of sensor compatibility and plug-and-play

In addition, the existing sensor interface is also incompatible with the bus protocol, the protocol standard is not uniform, and the data format conversion is complicated, which greatly reduces the data processing speed
