The embodiment of the invention discloses a bus conflict detection method and device, detection equipment and a storage medium. The method comprises the steps: initializing system parameters and interrupt parameters; starting a timer interrupt and a serial port interrupt; starting an external interrupt, and starting a counter to start counting; if it is detected that a timer interrupt function operates, adding one to the counter; if it is detected that an external interrupt function operates, resetting the counter; and determining whether the count value of the counter at the current moment isgreater than a set counter counting threshold value or not, if so, determining that the bus is in an idle state, and otherwise, determining that the bus is in a busy state. The bus conflict detectionmethod without a master-slave structure is used, detection is carried out through the external interrupt, the communication response speed is high, the operation efficiency is high, and the system power consumption is low.
Description
technical field [0001] The embodiment of the present application relates to a bus detection technology, and in particular to a bus conflict detection method, device, detection device and storage medium. Background technique [0002] In traditional industrial control applications, the bus system usually uses a master-slave structure. For example, the MODBUS bus uses a communication scheme of one master and multiple slaves. Although the problem of bus conflict is solved, the response speed of the entire system is slow and the efficiency is low. And It is very power-hungry and cannot be used for low-power system solutions. Contents of the invention [0003] The present application provides a bus conflict detection method, device, detection equipment and storage medium to solve the problems of slow response speed, low efficiency and high power consumption in bus conflict detection in the prior art. [0004] The present invention adopts following technical scheme: [0005] In...
