Qian Lin numbering machine is developed for the queuing system currently used in the window service industries such as banks, hospitals, customs, telecommunications, industry and commerce, taxation, etc. Effectively improved the problems of complex installation, frequent failures and short service life. Wired queuing system. It is completely wireless and easy to install and operate.

System introduction:

(1) System composition: The system consists of a number issuing host, a teller pager, a main display screen, a window display screen and a voice system. Each component of the system is equipped with a wireless transceiver module, which makes it a wireless queuing system through communication protocols.

(2) System function: The customer obtains the queuing number in the numbering host and waits for the call from the sales staff. The salesperson performs the next call, repeated call or previous call through the pager. During the operation, the number of customers accepted is displayed on the pager display screen, the corresponding window display screen and the main display screen, and the caller can call the number by voice. After each caller performs the next operation, the number of people waiting displayed by the caller and the number issuing host is automatically reduced by one.

& gt& gt Features:

1, stable transmission and high reliability: this FSK modulation wireless module transmission mode has high reliability and effectively avoids the dead angle problem in other wireless transmission. After testing, the data transmission error rate is only 10-5.

2. Low power consumption: The power consumption of our wireless module is mA. In the system design, there is no need to increase the load capacity of the power supply in the equipment.

3. Convenient installation and use: The adopted wireless module can be embedded into the customer's original system or plug and play with the completely transparent module according to the situation. The customer does not need to do any development work for the wireless data transmission module.

Technical indicators of wireless data transmission module:

1、

Stable transmission, high reliability and excellent performance: Based on FSK modulation, efficient forward error correction channel coding technology is adopted to improve the ability of data to resist burst interference and random interference. Under the line-of-sight condition, the antenna position is >: 3m, and the reliable transmission distance is about 800m (ber =10-6/1200bit/s).

2. Low power consumption: normal standby: 14mA, transmission: 50mA, sleep power consumption: 10μA,

3. Small size, light weight and convenient installation and use;

4. Low cost: the cost of adopting this wireless module is very low;

5. Micro-power transmission with transceiver status indication: the transmission power is 10mW, and the transceiver status is displayed by LED, which is convenient for observing the working conditions of the module;

6. Multi-channel: 9 channels are provided in standard configuration (8 channels or 16 channels can be provided in special order) to meet users' various communication combinations;

7. Three interface modes: standard RS-232/ TTL/ RS-485 interface (one out of three);

8. Intelligent data control: the module can automatically complete receiving, sending, conversion and control. There is no special control of customers;
