Problems solved by technology

[0004] However, in the above-mentioned traditional management method, the management background needs to spend a lot of time to check whether such external events have occurred at each vehicle pile through MODBUS continuously, resulting in the consumption of network resources, and the real-time performance of obtaining external events is poor.

Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0049] The master-slave communication method provided by this application can be applied to such as figure 1 shown in the application environment. Among them, a plurality of sub-stake slave devices 102 communicate with the parent stub master device 101 through the network, and the sub-stake slave devices 102 detect whether there are external events that need to be reported. Idle, if the arbitration bus is idle, the child stub slave device 102 sends the reporting information of the external event to the parent stub master device 101 through the arbitration bus, after the s...

Abstract

The invention relates to a master-slave communication method, device and system, a computer device and a readable storage medium. The master-slave communication method comprises the steps of detectingwhether an external event needing to be reported exists or not; if the external event needing to be reported exists, monitoring whether an arbitration bus is idle or not; and if the arbitration bus is idle, sending the report information of the external event to a mother pile main device through the arbitration bus, so that the mother pile main device acquires the event information of the external event through the MODBUS. By adopting the method, the real-time performance and the efficiency of acquiring the external event of each sub-pile slave device by the mother pile main device can be improved.

Description

technical field [0001] The invention relates to the technical field of public transport leasing, in particular to a master-slave communication method, device, system, computer equipment and readable storage medium. Background technique [0002] In recent years, in order to promote green travel and reduce motor vehicle congestion, cities have deployed a large number of public means of transportation, such as public bicycles, and users can rent public bicycles for short-distance transportation. [0003] At present, the management network to which the docked bicycles belong is based on MODBUS (serial communication protocol) for vehicle management. According to the regulations of MODBUS, the management background needs to regularly poll the docks of each docked bicycle to obtain the external events of each dock. , in order to manage the bicycles with piles, external events such as: returning the car and locking it, insufficient power, citizen card access, sudden failure, etc. ...
