Abstract

The invention relates to the field of system communication scheduling algorithms, in particular to a system communication scheduling algorithm based on a Canbus. According to the specific scheme, the system communication scheduling algorithm is achieved through the following steps of firstly, sending address statements to a monitoring box when sub-devices are powered on, and sending address statement request commands to the sub-devices when the monitoring box is powered on; secondly, when receiving the address statement commands sent by the monitoring box, enabling the powered-on sub-devices to start the address statements which need to be responded to after random delay is conducted. By means of the steps, the system communication scheduling algorithm solves the address automatic distribution problem and the address conflict problem between the sub-devices and solves the problem that the operation control and the running state monitoring of all node devices can not be monitored in time; the Canbus can report device alarms in time when the number of online communication nodes is large, protection control can be conducted according to the alarms, the online state and the connection losing state of online devices can be effectively detected through the Canbus, and device display control over multiple nodes can be achieved through the Canbus.

Description

technical field

[0001] The invention relates to the field of system communication scheduling algorithms, in particular to a Canbus-based system communication scheduling algorithm. Background technique

[0002] At present, the monitoring and control automation of yacht power equipment is not high. The monitoring of various electrical equipment such as generators, shore power, batteries, bilge pumps, and water leakage at the bottom of the ship has its own control and display panel for separate control and display. , read-through or information transmission is mainly in the form of point-to-point, that is, a sub-equipment is connected to a remote control display panel, and these monitoring display panels are scattered on the yacht's console, which reduces the space utilization of the bridge, and the equipment that is related to each other cannot be connected. When there are too many sub-devices and the yacht exceeds 60 feet, it will often cause insufficient equipment resources ...

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment, is not to limit the scope of implementation of the present invention to this;

[0028] Such as Figure 1 to Figure 2 As shown, the system communication scheduling algorithm based on the Canbus bus includes the following steps: step a: send address declaration to the monitoring box when the sub-device is powered on, and send an address declaration request command to the sub-device when the monitoring box is powered on; When the electronic sub-device receives the address declaration request command sent by the monitoring box, it needs to reply to its corresponding address declaration after starting a random delay; this method can effectively allow each sub-device to connect to the communication network smoothly, which is convenient and practical .

[0029] Such as Figure 3 to Figure 4 As shown, the system communication scheduling algorithm b...
