Remote laboratory controller

Abstract

The invention discloses a remote laboratory controller which can be used for finishing remote laboratory control in a single chip to replace the past structure realized through equipment such as a server and the like. The remote laboratory controller mainly comprises a control management module, a video processing module, a multipurpose interface module and a power management module, wherein the control management module operates on an in-chip dual-core processor, and the video processing module, the multipurpose interface module and the power management module operate on an in-chip field programmable gate array (FPGA). Software and hardware cooperatively work to remotely achieve functions such as access control, video watching and the like of a plurality of devices and development boards in the field of an experimental environment; meanwhile, the controller can be provided with a reconfiguration function for ensuring the real-time property of video transmission and also meeting the requirements of various special interfaces. Due to the adoption of the structure, the remote laboratory controller is small in size, low in power consumption and capable of reducing the cost and greatly improving the system flexibility.

Description

technical field [0001] The invention relates to a remote laboratory controller, which belongs to the remote laboratory control platform in the field of information technology. Background technique [0002] With the deepening of cloud computing and the current increase in the price of laboratory hardware equipment, cloud laboratories have also become a demand. Users do not need to visit the laboratory in person, they can remotely access the development board and experimental equipment in the laboratory, and watch the experimental results through the camera. An important device in the cloud laboratory is the remote management and control hardware platform for the existing equipment and development boards in the laboratory. This platform can obtain the status information of the equipment, and complete the power-on / Power off; provide laboratory site conditions to remote customers through the camera, which is convenient for users to control. [0003] At present, the remote lab...

Problems solved by technology

The image acquisition part generally uses an external image acquisition card to complete the acquisition of video images, and the processing and compression transmission of video images are all completed by the server-side processor, which not only increases the burden on the server, reduces performance, but also increases the system's capacity. cost

At the same time, due to the difference in network bandwidth, the video often has a delay, and the results of the field experiment cannot be watched in real time.

At the same time, the current X86-based server platform generally only provides 1-2 serial port interfaces, so it is often necessary to purchase an additional serial port junction box (Hub) to realize access control to multiple development boards, but the number of scalable serial ports is also fixed

And some special interfaces often need to customize the adapter board, the system has great limitations
