Wireless Pager +5V power supply:
A, wireless pager core power supply and physical characteristics
Power supply design of queuing paging call screen machine:+5V (10%) low-voltage power supply is adopted, and power can be directly obtained through computer USB port or mobile phone charger with USB A port, with current less than 200mA, low energy consumption and high safety, thus avoiding the risk of high-voltage power supply.
Physical form: small keyboard design, including numeric keys and function keys (such as "Call" and "Call"), with compact key layout and convenient operation, which is suitable for window staff to get started quickly.
B, queuing paging call screen machine communication control function and system linkage
Core function: As a key component of the queuing paging machine, it is used for staff to actively call customers to the corresponding window to handle business, and supports operations such as single-key calling and multi-number continuous calling.
Coordination of queuing paging call screen machine system: through communication controller (including wireless transmitter and receiver and antenna), it is linked with queuing machine host and window display screen. After the call signal is transmitted by wireless module, it will trigger voice system broadcast (such as "Please go to window A001") and screen information to be displayed synchronously.
C, queuing paging call screen machine wireless communication performance and stability guarantee
Wireless module adaptation: wireless communication transceiver with USB interface, without external power supply, directly takes power from the computer and realizes data transmission, reducing cable connection and simplifying installation process.
Signal reliability of queuing paging call screen machine: the wireless control module adopts stable communication protocol to ensure that the call signal is not stuck or lost in an environment where multiple devices are running at the same time (such as a multi-window scene in a bank), and the response delay is low.
D, cooperation with other components of the queuing paging machine
Linkage between the queuing and calling machine and the touch screen ticketing machine: receiving the queuing number information allocated by the ticketing machine, and the staff can initiate a call by inputting the corresponding number through the pager, thus realizing the closed loop of the process of "taking number-queuing-calling number".
The queuing paging call screen machine cooperates with the evaluator: in some scenarios, the service evaluator can be linked after the call is completed, and the customer can feedback the satisfaction through the evaluator after handling the business, and the pager temporarily stores the evaluation trigger signal.
The queuing paging call screen machine cooperates with the display screen: after the call instruction is sent, the window display screen and the comprehensive display screen update the paging information in real time to ensure that the customer can clearly obtain the guidance in the waiting area.
E. Applicable scenarios and operational advantages of queuing paging call screen machines
Scene adaptation of queuing paging machine: it is widely used in multi-window scenes such as banks, hospitals, government halls, etc., especially in high-frequency service scenes that require frequent paging, and improves the efficiency of window service.
Operation advantages of queuing paging call screen machine: low-voltage power supply does not need additional wiring, and the installation is flexible; Keypad design reduces misoperation, supports multilingual call settings, and adapts to different working habits.
F. Durability and maintenance characteristics of queuing paging call screen machine
Hardware durability of queuing paging machine: the buttons are made of wear-resistant material and can withstand high-frequency pressing; The shell has certain anti-drop and anti-scratch performance, which is suitable for long-term use in noisy environment of windows.
The queuing and paging call screen machine is easy to maintain: it can be replaced separately in case of failure, without stopping the whole queuing system; The wireless module supports hot plug, which is convenient for quick troubleshooting of communication problems.
