The embodiment of the present application discloses a bus conflict detection method, device, detection equipment and storage medium. The method includes: initializing system parameters and interrupt parameters; enabling timer interrupts and serial port interrupts; enabling external interrupts, and enabling counters to start counting ;If it is detected that the timer interrupt function is running, then the counter count is increased by one; if it is detected that the external interrupt function is running, then the counter count is cleared; judge whether the count value of the counter at the current moment is greater than the set counter count threshold, and if so, determine The bus is in an idle state, otherwise, the bus is determined to be in a busy state. The bus collision detection method without master-slave structure is used to detect through external interrupts, and the communication response speed is fast, 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...
