Abstract

The invention provides a serial communication system, a serial communication method and an intelligent door lock. The serial communication system comprises first equipment, second equipment and third equipment, the first device at least has a first serial port, the second device at least has a second serial port, and the third device at least has a third serial port, wherein the sending end of the first serial port is connected with the receiving end of the second serial port and the receiving end of the third serial port through a first bus, so that the first equipment sends data to the second equipment and/or the third equipment; the receiving end of the first serial port is connected with the sending end of the second serial port and the sending end of the third serial port through a second bus, so that the first equipment receives data sent by the second equipment and/or the third equipment. According to the serial port communication system provided by the invention, the cost of hardware such as an extended chip does not need to be increased, the circuit layout is simplified under the condition of reducing the number of serial ports, and the difficulty of the circuit layout is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of communication serial ports, in particular to a serial communication system, a serial communication method and an intelligent door lock. Background technique [0002] Some electronic products sometimes need to be integrated with multiple small embedded devices (hereinafter referred to as devices), and these multiple devices use serial ports to communicate and cooperate with each other. For example, when 3 devices are integrated, each device needs to provide 2 serial ports to communicate with the other 2 devices; at the same time, each device may also need to use other serial ports to access some peripherals. [0003] Due to hardware interface limitations, these devices cannot provide enough serial ports to meet these functions. The following solutions can be adopted in the prior art: use a dedicated UART bridge / expansion chip to expand one serial port into multiple serial ports. However, this me...
