Intelligent digital paging station is an upgraded paging system that integrates modern communication technologies such as IP networks and digital modulation with intelligent management functions. It is designed specifically for industry scheduling, emergency communication, IoT applications, and other scenarios.
The selection of intelligent digital paging stations requires comprehensive consideration of multiple factors such as functional requirements, audio quality, hardware configuration, stability, and ease of operation. The following are specific points:
Functional requirements:
Paging method: Determine the paging range and partition requirements based on the usage scenario. For large places such as shopping malls and parks, it is necessary to choose equipment that can perform zone paging and group paging for multiple areas, and preferably has a one click fully open function for rapid emergency broadcasting.
Intercom function: If you need to communicate between paging stations or with other terminals, you should choose a product that supports this function, and also pay attention to whether there are auxiliary functions such as voice prompts and flashing prompts for timely response.
Recording function: For scenarios where there is a need for post event traceability, such as airports, stations, etc., it has audio log recording function, which can record in real time and view the playback of paging stations, which is more in line with the requirements.
Audio quality:
Frequency response: High quality paging stations typically have a frequency response range of 20Hz-20kHz, ensuring complete sound reproduction and good performance in both high, medium, and low frequencies.
Distortion: The distortion should be as low as possible, generally ≤ 0.5%, to ensure clear and undistorted sound, and to restore the speaker's true voice.
Signal to noise ratio: A signal-to-noise ratio of ≥ 80dB is better, as it can reduce background noise interference and make speech clearer.
Hardware configuration:
Display screen: It is recommended to choose products equipped with a ≥ 7-inch true color LCD display screen. The capacitive touch screen is more convenient to operate, and the graphical interface can display real-time partition status and other information, making it easy to operate and monitor.
Processor: The paging station adopts an embedded real-time system platform and high-performance ARM processor, with fast startup speed, stable system operation, and can ensure long-term reliable operation.
Interface: Select devices with rich interfaces according to actual needs, at least 1 line input, 1 line output, 1 headphone monitoring interface, etc., to facilitate the connection of external audio devices. At the same time, RJ45 network interface is required, supporting TCP/IP transmission protocol to ensure stable network connection.
stability
System architecture: The embedded real-time system platform is relatively more stable, less susceptible to virus interference, and can ensure the continuous normal operation of the paging station.
Power supply design: Products that support dual power supply modes of PoE and 12V DC are better, and can be used in different power environments. When one power supply mode fails, the other can ensure the normal operation of the device.
Convenience of operation:
Shortcut buttons: A paging station with manual shortcut buttons that can quickly implement paging functions in emergency situations, improving work efficiency.
Screen calibration and backlight setting: A paging station with screen calibration function and adjustable backlight lighting time, which can ensure screen operation accuracy and achieve energy-saving operation.
