Cascade bus signal receiving circuit and control system thereof

Abstract

The invention belongs to the field of electronic technology, and discloses a cascade bus signal receiving circuit and a control system, wherein the cascade bus signal receiving circuit is arranged ina power supplying cable and comprises a first diode, a signal receiving module, a processor and a fourth capacitor. The signal receiving module is electrically connected with the anode of the first diode, the cathode of the first diode and the processor. The signal receiving module is used for analyzing a control signal and transmits the control signal to the processor. The processor is used for controlling a slave computer load according to the control signal. A cascade bus control system comprises power supply equipment, a host computer, at least one slave computer and at least one slave computer load. Each slave computer comprises a current bypass circuit and a signal receiving circuit which are connected in parallel. The cascade bus signal receiving circuit and the control system are suitable for performing intelligent home reconstruction on a decorated house and furthermore can eliminate a signal noise in the signal receiving circuit, thereby facilitating accurate control over theslave computer load.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a cascade bus signal receiving circuit and a control system. Background technique [0002] Smart home is based on the residence as a platform, using integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology to integrate the facilities related to home life, build an efficient management system for residential facilities and family schedules, and improve Home safety, convenience, comfort, artistry, and to achieve an environmentally friendly and energy-saving living environment. In order to intelligently control the household equipment, it is necessary to exchange data with each household equipment, for which it is necessary to establish a communication link with each household equipment. [0003] At present, various household devices can be connected through RS-485, KNX, CAN, C-Bus,...

AI Technical Summary

Problems solved by technology

[0004] For the current methods of controlling household equipment, RS-485, KNX, CAN, C-Bus, SCS-BUS, LonWorks, Modbus and other buses all need to lay out bus cables independently, because the laying of bus cables needs to be done on the wall or on the ground Grooving can cause damage to the walls or floors of an existing home and is therefore not suitable for smart home retrofitting of an existing home

In the prior art, there have been household equipment control systems that do not cause damage by destroying and decorating the walls or the ground of the house. However, in the prior art, when the control system receives the control signal, due to the characteristics of the circuit itself, signal noise will be generated. When the transmission rate of the control signal is high, the existence of signal noise will easily cause the result that the control signal cannot be analyzed correctly, which will have a negative impact on the control of household equipment
