Benefits of technology

This patented device has two main benefits that make it more efficient than traditional systems. It uses both CPU (Central Processing Unit) processing capabilities with caching techniques instead of just one unit's ability to respond quickly. Additionally, this system allows users to connect different types of devices without having to install multiple units at once.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving wireless networks that connect multiple devices with each other through wired connections due to differences in their respective types of communications standards. Current solutions require purchasing specialized equipment at considerable cost overall, making them difficult to install across all possible combinations without sacrificing efficiency.

Abstract

The invention relates to a low-voltage electrical appliance communication protocol adapter which comprises double single chips, double Modbus-RTU protocol converting circuits, a Profibus-DP, a DeviceNet protocol converting circuit, an off chip data memory, an LCD (liquid crystal display) screen and a keyboard, wherein on chip universal asynchronous receiver-transmitters of the double single chips are respectively connected with the Modbus-RTU and an RS485 level converting transceiver circuit; an on chip control local area network is respectively connected with double DeviceNet converting transceiver circuits to finish acquiring low-voltage electrical appliance data and responding to bus commands and events; meanwhile, I2C communication modules of the single chips are connected with the off chip data memory based on I2C to finish storing the data and extracting processed low-voltage electrical appliance parameters. Due to the adoption of double processor operations and a caching technology, technical schemes such as response time, and the like when other adapters are operated are reduced so as to ensure that the low-voltage electrical appliance communication protocol adapter becomes a centralized controller, a small network server and an adapter. The adapter can hang at most three buses, thereby increasing the adaptability of low-voltage electrical appliances during networking and facilitating users mounting.
