Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] In the embodiment of the present invention, the clock signal and the data signal occupy a bus for transmission, and the data transmission between the master and the slave is realized by generating three kinds of bus data transmission signals of different level stages, and at the same time, the master transmits data to the slave. Carry out charging to ensure that the communication of the bus data transmission system works normally.

Abstract

The invention is applied to the field of data communication and provides a bus data transmission method. The method comprises the following steps of: synchronously superposing a host clock signal and a host data signal into a bus transmission signal; and transmitting the bus transmission signal to a slave in a form of a packet through a bus. Data transmission between a host and the slave is realized by transmitting the clock signal and the data signal of a bus system through the bus; the slave is charged by the host through the bus at the same time; under the condition of small data transmission amount and low data transmission speed, the method plays a role in simple communication circuit and good lightning protection effect; and the wiring cost is greatly saved.

Description

technical field [0001] The invention belongs to the field of data communication, in particular to a bus data transmission method and system. Background technique [0002] In industrial application scenarios such as alarm systems and meter reading systems, the communication distance between the host and the slaves in the system is long, and the communication between the host and the slaves does not require high data transmission rate and data transmission volume. , in which case a conventional bus system such as I 2 The C bus system needs four wires to complete the communication between the master and the slave: power wire, ground wire, data wire and clock wire. The wiring is complex and costly, so it has no advantages in the above application scenarios. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a bus data transmission method, aiming at solving the problems in the prior art that the wiring cost of the bus syste...
