A can-bus-based automated office conference presentation system and its control method

Abstract

A kind of automatic office meeting demonstration system based on CAN bus provided by the present invention comprises: CAN bus communication circuit, comprises at least one CAN controller and CAN transceiver, has receiving, sending function and can finish message filtering; Main control module , several controller nodes, which are connected to the CAN controller, and each node can independently complete the corresponding data processing and realize the communication function with the CAN bus communication circuit; a plurality of demonstration devices, which are connected to the controller node, are designed by the present invention Developed an automated office conference demonstration system based on CAN bus, which can directly start the controller node to control the demonstration device, and can complete text communication, graphic conference, text transmission and voice communication between employees, and is based on CAN bus The distributed architecture can add and delete node devices at any time, the logical relationship is simple, and the failure rate is reduced. The present invention also provides a CAN bus-based automated office conference demonstration control method.

Description

technical field [0001] The invention relates to the field of automated office, in particular to a CAN bus-based automated office conference presentation system and a CAN bus-based automated office conference presentation control method. Background technique [0002] Multimedia conferencing system, also known as video conferencing system, refers to two or more individuals or groups in different places, through transmission lines and multimedia equipment, to transmit sound, video and document data to each other to realize instant and interactive communication, in order to realize System equipment for conference purposes. [0003] However, due to the limited display space and the uncertainty of the number of participants, the terminal device needs to have certain flexible arrangement processing capabilities. Teleconference is a conference mode that uses telephone as a tool and telephone line as a carrier to hold meetings. It has the characteristics of rapid conference arrangem...

Problems solved by technology

However, due to the pre-set procedures of the meeting management system, the meeting cannot be started immediately, thus delaying the best time for the meeting presentation, and it takes a lot of time to integrate and arrange meeting issues before the meeting, which is a waste of time

[0006] The invention application with the application number 201910070006.9 discloses a conference management method and system. By setting user accounts and privileged accounts, different authority operations are performed on the venue. Although the time required for the privileged account to initiate a video conference is reduced, it meets the needs of on-site conference demonstrations. For the requirement of high timeliness, but only changing the control system authority of the conference equipment, the problem of single purpose of the conference equipment, complex connection, complex logical relationship, difficult installation and configuration have not been solved, and the conference equipment is prone to failure.

[0007] The invention document with the application number 200710135914.9 discloses a pointing control system for a multi-party presentation conference. A control module is installed in the system, and any participating member in the conference can manipulate the presentation by controlling the mouse, edit and demonstrate the presentation on the display , but the problem caused by this is that all participants have the same control authority and can demonstrate the presentation, which will cause confusion in the presentation, and it will take a lot of time to integrate and arrange meeting issues before the meeting, which is a waste of time
