Description

TECHNICAL FIELD

[0001] The utility model relates to monitoring technical field, concretely is a kind of double CAN safety monitoring system for servo driver. BACKGROUND

[0002] The "double CAN safety monitoring system for servo driver" refers to a technical solution that combines servo driver and double CAN bus safety monitoring system, which is commonly used in industrial automation field, especially in applications requiring high precision and high safety control. Or servo driver is a device that controls servo motor, mainly used in precise motion control system. It adjusts the action of motor by receiving control signals (such as position, speed, torque), and is widely used in automation equipment, robots, CNC machine tools and other fields. CAN bus (Controller Area Network) is a common fieldbus technology, widely used in automotive and industrial automation field. It is used to realize communication between multiple devices, so that different controllers, sensors and actuators can exchange data efficiently and safely. Double CAN bus system usually refers to using two CAN buses for communication at the same time, one of which may be used for real-time data exchange, and the other for redundancy or safety control. This configuration can provide higher reliability and safety, especially in applications with high fault tolerance requirements. Safety monitoring system is used to ensure that devices and systems meet safety standards during operation, to prevent accidents or equipment failure. In servo drive system, safety monitoring system involves real-time monitoring of motor position, speed, acceleration, etc. to ensure they operate within a safe range.

[0003] At present, the monitoring device will have dust attached to it after long-term use, and the attachment of dust will affect the shooting clarity of the monitoring device. Some monitoring devices will set a cleaning plate that can move up and down or left and right to clean the dust on the monitoring device. Although this can clean the dust on the monitoring device, the cleaning plate that moves up and down or left and right cannot clean the dust in the gap on the monitoring device, and when the cleaning plate passes through the gap on the monitoring device, some of the dust cleaned by the cleaning plate will be trapped in the gap on the monitoring device, which will result in poor cleaning effect of the monitoring device.
