Technical Field

[0001] This application relates to the field of queuing and calling system technology, and in particular to a data transmission device and equipment. Background Technology

[0002] In existing queuing and calling systems, the pager terminals primarily communicate with the calling host via serial communication, limiting the distance between the pager and the host.

Adding pager terminals necessitates the local deployment of additional calling hosts. Therefore, the serial communication method in existing queuing and calling systems imposes significant limitations on deployment and use, lacking flexibility and restricting application scenarios.

[0032] like Figure 2 The present application shows a data transmission apparatus 100 according to one embodiment, wherein the data transmission apparatus 100 includes:

[0033] The system comprises an interface module 110, a network module 120, a first circuit 130, a second circuit 140, and a wireless communication module 150, wherein...

[0034] Network module 120 receives Ethernet data through interface module 110, and converts the Ethernet data into TTL signals and transmits them to the first circuit 130 and the second circuit 140 respectively.

[0035] The first circuit 130 converts the TTL signal output by the network module 120 into RS232 data and transmits it to the wireless communication module 150. The wireless communication module 150 converts the RS232 data into a wireless signal and transmits it to the wireless terminal.

[0036] The second circuit 140 converts the received TTL signal into RS485 data and transmits it to the wired terminal.

[0037] The interface module 110 includes an RJ45 interface, through which a network cable can be connected to a local Ethernet network. The other end of the network cable is connected to the local Ethernet network, allowing the data transmission device 100 to communicate with the queuing system's host via the local Ethernet. When the queuing system triggers a call, the host can broadcast the call data to the local Ethernet network. When set to receive Ethernet data mode, the data transmission device 100 receives the corresponding Ethernet data through the interface module 110. A partial circuit diagram of an exemplary interface module 110 is shown below. Figure 3As shown, the system includes a terminal block RJ1 for input signals. Pins 1-8 of terminal block RJ1 correspond to pins 1-8 of the RJ45 interface. For example, pin 3 of RJ1 is connected to the signal transmit T pin of the RJ45 interface, and pin 6 of RJ1 is connected to the signal receive R pin of the RJ45 interface. When the system is set to receive Ethernet data via a jumper block, it ensures correct reception of Ethernet data. Pins 9-12 of terminal block RJ1 are electrically connected to the corresponding status indicator circuits, and pins 13 and 14 are electrically connected to the analog ground AGND. The received data signal is transmitted to the network module 120 after passing through the PoE-network transformer. The network module 120 converts it into a TTL signal and transmits it to the first circuit 130 and the second circuit 140, respectively. The first circuit 130 converts the TTL signal into RS232 data and transmits it to the wireless communication module 150. Through the wireless communication module 150, the signal is wirelessly transmitted to the wireless pager terminal for call generation. The wireless communication module 150 can communicate with the wireless pager terminal via Bluetooth, WiFi, or other wireless communication methods. The wireless communication method between the module and the pager terminal is not limited here; any wireless communication method applicable to this application is included within the scope of protection of this application. The second circuit 140 converts the TTL signal into RS485 data and transmits it to the wired pager terminal via cable for calling numbers. The data transmission device 100 can process the received queuing data from the queuing system transmitted via local Ethernet and send it to the wireless pager and / or wired pager. One host can cover a large area, reducing limitations in engineering deployment and use, improving flexibility, and enriching application scenarios.

[0038] Optionally, the network module 120 also converts the received WiFi data into TTL signals and transmits them to the first circuit and the second circuit respectively.

[0039] The data transmission device 100 also supports communication with the host of the queuing and calling system via a wireless WiFi network. When the queuing and calling system triggers a call, the host can broadcast the call data to the WiFi network. When set to receive WiFi data mode, the data transmission device 100 can receive the WiFi data corresponding to the call data through the network module 120. The network module 120 converts the WiFi data into a TTL signal and sends it to the first circuit 130 and the second circuit 140 respectively. The first circuit 130 converts the TTL signal into RS232 data and sends it to the wireless communication module 150, which then wirelessly transmits it to the wireless pager terminal for calling. The second circuit 140 converts the TTL signal into RS485 data and transmits it to the wired pager terminal via cable for calling. The data transmission device 100 can process the queuing and calling system host call data received via the WiFi network and send it to the wireless pager and / or wired pager. One host can cover a large area, reducing limitations in engineering deployment and use, improving flexibility, and enriching application scenarios.

[0040] Optionally, the first circuit 130 also receives RS232 data through the interface module 110, wherein the first circuit 130 transmits the RS232 data to the wireless communication module 150, converts it into a TTL signal, and then transmits it to the second circuit 140.

[0041] The interface module 110 also includes an RS232 interface (DB9), such as... Figure 3In one example, pin 2 of RJ1 is connected to the signal transmission T pin of the RS232 interface, and pin 3 of RJ1 is connected to the signal reception R pin of the RS232 interface. When set to receive RS232 data mode via a jumper block, correct reception of RS232 data is ensured. Communication with the queuing system's host is possible via the RS232 bus. When the queuing system triggers a call, the host can broadcast the call data to the RS232 bus. When set to receive RS232 data mode, the first circuit 130 of the data transmission device 100 receives the corresponding RS232 data through the interface module 110. The first circuit 130 can directly transmit the RS232 data to the wireless communication module 150, which then wirelessly transmits it to the wireless pager terminal for call processing. Alternatively, the first circuit 130 converts the RS232 data into a TTL signal and sends it to the second circuit 140. The second circuit 140 converts the TTL signal into RS485 data and transmits it via cable to the wired pager terminal for call processing. The data transmission device 100 can process the queuing and calling data received from the host of the queuing and calling system transmitted via RS232 bus and send it to the wireless pager and / or wired pager. One host can cover a large environmental area, and is no longer subject to too many restrictions in engineering deployment and use, which improves flexibility and enriches application scenarios.

[0042] The data transmission device 100 can be configured according to the communication method between it and the host of the queuing system (based on local Ethernet, WiFi network, or RS232 bus) to ensure that the relevant modules are in the corresponding operating mode.

Figure 4As shown, the DC12V can be reduced to a stable DC5V by the 78L05 voltage regulator circuit, which can power the wireless communication module 150. Then, the DC5V can be reduced to a stable DC3.3V by the AMS1117-3V3 voltage regulator circuit, which can power the network module 120, the first circuit 130 and the second circuit 140.

[0046] Optionally, the network module 120 includes a ZLSN7004 module.
