Communication interface detection method and electronic device

Abstract

The invention discloses a communication interface detecting method and an electronic device, belongs to the technical field of hardware detection, and aims at solving the problems in the prior art that detection of device interfaces needs a computer, thus occupying resources and having high cost, furthermore, data transceiving needs to be implemented between the device and the computer, thus having complex process, long time and low efficiency. On the one hand, the invention provides the communication interface detecting method which comprises the following steps: a data sending end and a data receiving end of an interface are connected; the sending end sends detecting data; the receiving end receives the detecting data; consistence between the sent detecting data and the received detecting data is compared; on the other hand, the invention provides the electronic device which comprises the communication interface and a communication interface detecting device, and the communication interface detecting device comprises a sending unit, a receiving unit and a comparing unit. The communication interface detecting method and the electronic device are applicable to the communication interface detection of electronic devices.

Description

technical field [0001] The invention relates to a hardware detection method, in particular to a communication interface detection method and electronic equipment with a communication interface detection device. Background technique [0002] The serial port of the set-top box is a common communication interface, generally using a standard RS232 nine-pin serial port, which is widely used and convenient for debugging and local upgrade. During the production process of the set-top box, the serial port must be tested to determine whether the serial port is normal. [0003] The existing detection method is to use a computer to detect, and the specific method is: a serial port detection software is installed in the computer, and the set-top box is connected to the serial port of the computer with a serial port line; the serial port detection program embedded in the set-top box program is started, and then the serial port in the computer The detection software sends specific data t...

AI Technical Summary

Problems solved by technology

[0004] The existing set-top box serial port detection method requires the use of a computer and serial port detection software, which occupies high equipment resource costs; the detection process also requires data transmission and reception between the computer and the set-top box, which is complicated, takes a long time, and is inefficient
