Problems solved by technology
[0005] In addition, the server is generally installed in the cabinet with other servers on site. Such isolation conditions will cause the heat in the cabinet to increase sharply in some areas, resulting in a reduction in the operating performance and service life of the server and other servers. Therefore, through Introduce cold air flow to cool the servers and other servers in the cabinet in real time, and remove the problem that the heat in the cabinet will increase sharply in some areas, ensuring that the installed servers and other servers run in a normal temperature range, and can improve the installation at a high speed The operating performance and service life of servers and other servers, and how to build a cabinet to allow the cold air to flow in the cabinet to obtain better cooling efficiency is indeed a difficult problem that has been difficult to solve for a long time

Embodiment Construction
[0025] Below in conjunction with accompanying drawing and embodiment, content of the invention will be further described:
[0026] Such as Figure 1-Figure 5 As shown, the digital network voice room system includes the Internet 19, a server 20, a voice communication card 21, a voice communication switching host 22, a voice communication switching extension 23 and a digital voice learning terminal 24. Each part is connected sequentially by a special die line, including a power line and a data line. The server 20, the voice communication card 21, and the voice communication exchange host 22 are installed on the teacher's desk, and the voice communication exchange extension 23 and the digital voice learning terminal 24 are installed. on student desks;
[0027] The server and other servers form a host group and are installed in a cabinet, which includes a perforated plate S1 with several through holes, a guide piece S2, a host group S3, and a working room with a rectangular paral...

The invention provides a digital network language lab system and a method. A server and other servers form host groups to be arranged in a cabinet body, wherein the cabinet body comprises a porous plate with a plurality of through holes, guide plates, the host groups, a work room with a rectangular groove in the top end, ventilators and a top cover; the rectangular groove in the top end of the work room is covered by the top cover; the top cover is connected with the work room through a bolt; the porous plate is arranged at the head part of the work room and can filter out particle impurities in airflow; and an embedded head is arranged on the edge of the porous plate and is embedded into an embedded opening formed in the wall of the embedded head to achieve the function of regular disassembly to clean up the dirt. The defects that the frame omission phenomenon frequently appears during uploading or downloading of an information frame in the prior art and heat in the cabinet body is sharply increased in partial areas are avoided by combining the method of the digital network language lab system.
Description
technical field [0001] The invention belongs to the technical field of speech labs for teaching, and in particular relates to a digital network speech lab system and method. Background technique [0002] In order to realize a fully digital dedicated network language room system in teaching, such a digital network language room system is now proposed, such as figure 1 As shown, it includes Internet 19, server 20, voice communication card 21, voice communication switching host 22, voice communication switching extension 23 and digital voice learning terminal 24. Each part is connected sequentially by a special die line, which includes a power line and a data line, using standard DB15 and DB9 connectors. Server 20, voice communication card 21, voice communication switching host 22 are installed on the teacher's desk, voice communication switching extension 23, digital voice learning terminal 24 are installed on the student's desk. The server 20 transmits the digital voice fil...
