Camera zooming system based on CAN bus and control method

Abstract

The embodiment of the invention provides a camera zooming system based on a CAN bus and a control method, and belongs to the technical field of wireless zooming video surveillance, the camera zooming system comprises a CAN bus display, a converter and a camera, the output end of the CAN bus display communicates with the input end of the converter through the CAN bus, and the output end of the converter communicates with the output end of the camera through the CAN bus, the CAN bus display sends a first zoom signal to the converter; the output end of the converter is wirelessly connected with the camera, and the converter is used for converting a first zoom signal communicated through the CAN bus into a wirelessly transmitted second zoom signal and transmitting the second zoom signal to the camera; and the camera is used for receiving the second zooming signal sent by the converter and zooming according to the second zooming signal. According to the processing scheme of the invention, the method is applied to the zooming control of the network camera, solves a problem that a conventional engineering machine cannot directly control the zooming of the network camera on site, and enables the operation to be more convenient and flexible.

Description

Technical field [0001] The present application relates to the field of wireless zoom video monitoring technology, and more particularly to a CAN bus-based zoom system and a control method. Background technique [0002] In the field of mechanical engineering, there is often a large-scale lifting equipment. The crane is one of the most common, and the crane is also known as a crane, which is widely used in large hoisting construction, and the working environment is relatively complicated. The crane is long, the self-structure is complicated, during operation, affected by the environment and its own, can not observe all current status and operational effects of the vehicle, and most of the number of vehicles can only be obtained by monitoring. . In the case of crane operation, there are many ways to monitor the state of the vehicle, but the integrated intuitiveness, real-time, technical maturity, and cost, most of which use video surveillance. [0003] When the crane operation is pe...

Problems solved by technology

However, due to the design cost of the wireless zoom video monitoring system of the crane and the limitation of internal space, the environment around the crane is not suitable for wiring with network cables to control the zoom function of the camera, and the existing display cannot directly connect the network camera, so A new zoom control method is required to control the zoom of the camera
