Abstract

The present disclosure provides a serial communication system, a serial communication method and an intelligent door lock. The serial communication system includes: a first device, a second device and a third device; the first device has at least a first serial port, and the second device has at least a first serial port. The second serial port and the third device have at least a third serial port; wherein, the sending end of the first serial port is connected to the receiving end of the second serial port and the receiving end of the third serial port through the first bus, so as to realize the communication between the first device and the second serial port. The device and / or the third device sends data; the receiving end of the first serial port is connected to the sending end of the second serial port and the sending end of the third serial port through the second bus, so that the first device can receive the second device and / or the third serial port. Data sent by three devices. The serial communication system provided by the present disclosure does not need to increase hardware costs such as expansion chips, simplifies the circuit layout under the condition of reducing the number of serial ports, and reduces the difficulty of circuit layout.

Description

technical field [0001] The present disclosure relates to the technical field of communication serial ports, in particular to a serial port communication system, a serial port communication method and an intelligent door lock. Background technique [0002] Some electronic products sometimes need to integrate multiple small embedded devices (hereinafter referred to as devices), and these multiple devices use serial ports to communicate and work together. 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 do not provide enough serial ports for these functions. The following solutions can be adopted in the prior art: a dedicated UART bridge / expansion chip is used to expand one serial port into multiple serial ports. However, this method requir...
