Embodiment 1

[0050] This embodiment provides a data communication system.

[0051] figure 1 A schematic diagram of the architecture of a data communication system provided in this embodiment, such as figure 1 As shown, the data communication system provided in this embodiment mainly includes: a master communication device 10 and a slave communication device 20 . Such as figure 1 As shown, in this embodiment, the master communication device 10 and the slave communication device 20 perform data communication through the two-wire communication interface, and when the master communication device 10 and the slave communication device 20 are forward connected through the two-wire communication interface, that is, the master communication The first communication sub-interface of the device 10 is electrically connected to the first communication sub-interface of the slave communication device 20 , and the second communication sub-interface of the master communication device 10 is electrically co...

Embodiment 2

[0057] This embodiment provides a master communication device 10, figure 2 A schematic structural diagram of a master communication device 10 provided in this embodiment. Such as figure 2 As shown, the main communication device 10 includes: a power supply interface 100 connected to a DC power supply, a first wired communication interface 110, a first main control chip 130, and a first energy storage component 140; wherein, the first wired communication interface 110 is composed of a first communication sub-interface 111 and a second communication sub-interface 112; the power supply interface 100 is electrically connected to the first communication sub-interface 111, and the first end of the first energy storage component 140 is connected to the power supply The interface 100 is electrically connected to the connection point of the first communication sub-interface 111; the second communication sub-interface 112 is electrically connected to the ground terminal GND_M of the m...

Embodiment 3

[0064] This embodiment provides another main communication device 10. The difference between the main communication device 10 provided in this embodiment and Embodiment 2 is that in this embodiment, the first main control chip 130 is also used for When the communication device 10 sends a high-level signal, it outputs a second signal from the control port.

[0065] In this embodiment, the first signal is a level signal whose voltage value is lower than the second voltage, wherein the second voltage is lower than the voltage value at the power supply interface; The level signal of the second voltage.

[0066] Such as image 3 As shown, the first energy storage component can be a capacitor ( image 3 shown in C1). The first end of the first energy storage component is respectively connected to the power supply interface ( image 3 V_MPWR shown), the first communication sub-interface ( image 3 Port 1 in the number 11 shown is the first communication sub-interface, port 2 in ...

The second wire communication interface is composedof a first communication sub-interface of the slave communication device and a second communication sub-interface of the slave communication device; the input end of the second signal collection circuit is electrically connected with the first communication sub-interface of the slave communication device, and a detection port of a second master control chip is electrically connected with the output end of the second signal collection circuit.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a data communication system. Background technique [0002] At present, electronic products are developing rapidly, and the external interfaces are mixed. For products with a main chip, there are generally external interfaces, and they have charging and communication functions at the same time. At present, in the wired communication interface of general electronic products, the charging interface is separated from the wired communication interface, that is, different signal lines are used to realize communication and charging, which requires at least three lines, requires a lot of hardware support, wastes resources, and most of them do not support it. Reverse connection function. With the continuous improvement of product comfort and user-friendliness, it is becoming more and more important to communicate with interfaces that are not limited to front and back.
