Embodiment 1

[0035] Please refer to figure 1 , figure 1 It is a flow chart of Embodiment 1 of the signal detection method provided by the present invention. The signal detection method is used to detect the communication signal between the master end and the slave end, the method is applied to the master end, the master end is provided with a signal detection circuit, and the method includes:

[0036] S100. Send a handshake signal for the slave end, and detect whether the slave end returns a valid signal through the signal detection circuit.

[0037] The handshake signal is a signal sent by the master to determine whether to establish a formal communication with the slave, and the master (Host) can send a message for the slave when the state of the communication port is connected to the slave (Device). The handshake signal from the slave terminal. Specifically, the master terminal can determine whether the communication port has a slave terminal access by detecting the voltage of the com...

Embodiment 2

[0069] Based on the above embodiments, the present invention also provides a terminal, the functional block diagram of which can be as follows image 3 shown. The terminal includes a processor, a memory, a network interface, a display screen and a temperature sensor connected through a system bus. Wherein, the processor of the terminal is used to provide calculation and control capabilities. The memory of the terminal includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The network interface of the terminal is used to communicate with external terminals through a network connection. The computer program implements a signal detection method when executed by a processor. The display screen of the terminal may be a liquid crystal display scree...

Embodiment 3

[0092] The present invention also provides a storage medium, the storage medium stores one or more programs, and the one or more programs can be executed by one or more processors to implement the signal detection method described in the above-mentioned embodiments A step of.

Abstract

The invention discloses a signal detection method, a terminal and a storage medium. The signal detection method is used for detecting a communication signal between a master end and a slave end, and comprises the following steps: sending a handshake signal aiming at the slave end, and detecting whether the slave end returns an effective signal or not through the signal detection circuit; and when the detection result is that the slave end does not return the effective signal, adjusting a detection parameter used for detecting the effective signal in the signal detection circuit, and detecting whether the slave end returns the effective signal according to the adjusted signal detection circuit until the detection result meets a preset condition. According to the invention, after the handshake signal aiming at the slave end is sent out, when the effective signal sent back by the slave end cannot be obtained, the signal detection circuit is adjusted instead of directly judging that formal communication with the slave end cannot be carried out, so that the compatibility of signals with different quality degrees is improved, and the communication success rate of the slave end is improved.

Description

technical field [0001] The present invention relates to the technical field of signal communication, in particular to a signal detection method, a terminal and a storage medium. Background technique [0002] Communication based on the USB2.0 protocol is very common. In many cases, the slave end is not directly connected to the master end through the port. Each module is directly inserted into the port of the main board, which causes the signal returned from the slave end to fluctuate due to the influence of wires or other modules, and is easily detected as an invalid signal by the predetermined detection circuit, which affects the communication success rate between the master end and the slave end. [0003] Therefore prior art still needs to improve and improve. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a signal detection method, terminal and storage medium aiming at solving the problem of low communicatio...
