Embodiment Construction

[0040] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0041] As shown above, in the related art, a detection sub-module may be included in a separate communication module (eg, MCU) to detect whether the communication module itself is normal according to its own simple communication protocol, and generate a corresponding state to indicate itself Current communication situation. This solution can only monitor the communication state of the communication module itself, but cannot continuously monitor the communication process of the entire communication system, which makes the communication process lack certain pertinence, and the reliability and security of the communication system are not high. The inventor thinks that a...

Abstract

The invention relates to a communication monitoring method and device. The method comprises the following steps: acquiring communication data from a connecting line between a first communication module and a second communication module; and judging whether the communication between the first communication module and the second communication module is normal or not according to the acquired communication data. According to the technical scheme, the communication data is acquired on the connecting line between the communication modules to detect the fault of the communication module, namely, the fault is judged according to the data transmitted from the outside of the communication module. Communication monitoring devices outside the two communication modules are used for acquiring communication data from a connecting line between the two communication modules to detect faults of the two communication modules, namely, the faults are judged according to data transmitted outside the communication modules. Therefore, the communication fault is detected from a new angle, so that the fault detection has high pertinence. According to the scheme, the reliability and detectability in the communication process are improved, so that the security of communication control is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a communication monitoring method and device. Background technique [0002] With the rapid development of communication technology, it has played a very important and even key role in various industries and fields such as mobile phones, automobiles, and home furnishing. If communication fails, it is likely to have serious consequences. Therefore, it is necessary to strictly monitor the state of communication, and find faults in time in the early stage, thereby reducing losses. [0003] Microcontroller Unit (MCU), also known as single-chip microcomputer or single-chip microcomputer, is to appropriately reduce the frequency and specifications of the central processing unit, and integrate peripheral interfaces such as memory, counter, USB, A / D conversion, etc. On a single chip, a chip-level computer is formed, which can control different combinations for dif...
