Part 1 - Company Profile

Guangzhou Huacheng Vocational Training College is located in the Wushan University Town of Guangzhou, covering an area of 10,000 square meters (15 mu) with a building area of 20,000 square meters. It enjoys convenient transportation, a beautiful environment, complete teaching facilities, and a strong faculty.

The college consists of multiple functional areas including teaching buildings, office buildings, an auditorium, and dormitories. With the continuous improvement of campus construction and the increasing enrichment of teaching activities, the demand for a campus broadcasting system has become increasingly urgent. An efficient, intelligent, and aesthetically pleasing broadcasting system can not only meet the needs of daily teaching and notification dissemination but also serve as a key tool to ensure the safety of teachers and students and maintain campus order in emergency situations.

Part 2 - Enterprise Requirements & Solutions

Requirement 1：The college aims to deploy an IP broadcasting system capable of meeting needs such as daily broadcast notifications and scheduled music playback.

Equiinet Solution：Deployment of the IoT Communication System - Broadcast Version: SINA DP System. The system supports music broadcasting, scheduled broadcasting, zoned broadcasting, intercom broadcasting, and text-to-speech broadcasting.

Meanwhile, the system allows audio import. College administrators can upload relevant music and schedule playback during breaks, sports events, and other periods.

Requirement 2：The college hopes to implement zoned management for targeted broadcasting in different areas.

Equiinet Solution：The IoT Communication System - Broadcast Version features flexible zoned management. College administrators can divide different broadcast zones through the system management terminal and quickly implement targeted broadcasting.

For example: Broadcasting teaching-related notifications in teaching buildings, event previews in the auditorium, and daily reminders in dormitories, greatly improving the accuracy and efficiency of information dissemination.

Requirement 3：The college requires the deployment of broadcast sound columns in different scenarios to match venue characteristics while ensuring aesthetic appeal.

Equiinet Solution：Considering the college’s various venues (classrooms, dormitories, auditorium, library, etc.), we have formulated the following plan:

（1）Deploy SIP sound columns EQ-X730P in classrooms, dormitory buildings, and other areas. Featuring an all-aluminum column design with a simple, elegant, and smooth appearance.

Flexible installation: Supports PoE power supply, and can be wall-mounted or ceiling-mounted. It ensures excellent sound transmission while meeting the aesthetic needs of classroom environments to the greatest extent.

（2）Deploy ceiling-mounted sound columns EQ-X30P in large spaces such as the auditorium and library.

Recessed installation: Flush with the ceiling after installation, saving space and evenly covering the entire area with sound. It achieves high-quality broadcasting while maintaining the overall aesthetics of the space.

Requirement 4：In case of emergencies, the college hopes to quickly conduct full-campus broadcasting to notify everyone promptly.

Equiinet Solution：The IoT Communication System - Broadcast Version is equipped with an emergency broadcasting function.

When an emergency occurs, college leaders can trigger the emergency broadcast button with one click on the system management terminal to immediately conduct full-campus broadcasting to all zones.

Requirement 5：To facilitate quick intercom and zoned broadcasting, the college hopes to realize one-click broadcasting via phones.

Equiinet Solution：Deploy EQ-A320i phones in the broadcast room and configure shortcut keys according to the college’s needs (e.g., Dormitories, Teaching Buildings, Auditorium, Emergency Broadcast).

Result：College leaders can press the "Dormitories" key on the phone to conduct intercom broadcasting to student dormitories instantly.
