System for switching and expanding multiple wireless transmission modes

Abstract

The invention provides a system for switching and expanding multiple wireless transmission modes. An upstream host communicates with a relay through a wireless transmission module, and the relay communicates with downstream nodes through the wireless transmission module. The wireless transmission modules comprise various types, and the sizes of all types of wireless transmission modules are consistent. Different types of used wireless transmission modules are integrated in the host. Each node is provided with a wireless transmission module of one type, and the type of the wireless transmissionmodule can be replaced at will. Different functions of different types of wireless transmission modules are shielded among the host, the relays and the nodes through software. According to the invention, different wireless transmission modes can be switched seamlessly, and only wireless transmission modules with the same size need to be replaced, so that the development efficiency is greatly improved. The repeated utilization rate of product data is high, and the product cost is reduced. Software is classified and developed, and the iteration period is short. Classification development is achieved, difference is shielded, the actual product maintenance amount is reduced, infinite expansion can be achieved through relays, and the application flexibility is greatly improved.

Description

technical field [0001] The invention mainly relates to a wireless transmission monitoring system used in the power environment monitoring industry and the security monitoring industry, in particular to a system for switching and expanding multiple wireless transmission modes. Background technique [0002] In the existing power environment monitoring industry and security monitoring industry, the current mainstream monitoring method is still through wired transmission. With the development of the Industrial Internet of Things, the wireless transmission method will gradually replace the wired transmission method. There are various ways of wireless transmission, such as Sub-G (such as 433Hz, Lora, etc.), 2.4GHz (such as Zigbee, BT, etc.) and other wireless transmission technologies contend. According to different application scenarios, the common practice is that only one wireless transmission method can be used. If you want to change to a different wireless transmission metho...

AI Technical Summary

Problems solved by technology

[0003] 1. The same application product, but the difference in wireless transmission mode causes the redesign of the entire product, the data utilization rate is very low, the coupling function increases, and the useless work increases;

[0004] 2. The availability rate is low, causing the corresponding cost to increase;

[0005] 3. The development cycle becomes longer;

[0006] 4. Software iterative development is not good;

[0007] 5. Increased product maintenance

[0008] In addition, due to the distance limitation of wireless transmission, the application range of existing wireless transmission systems is narrow and the scalability is not good
