Description

communication coordinator

This creation is about a communication coordination processor to provide more stable data transmission.

The module technology of wireless communication to RS232 used in the market uses the direct transmission method, which means that it directly uses the UART communication interface provided by the wireless module, and outputs directly through the RS232 electrical conversion chip. This connection method is commonly used in various The communication interface is transferred to RS232/422/485, such as WIFI, Bluetooth or Zigbee.

Due to the common problem of communication delay in wireless communication, on low-speed transmission equipment such as industrial equipment, buffer overflow will occur due to delay, so problems such as data loss will occur when a large amount of continuous data is transmitted.

This creation provides a communication coordination processor, which includes a wired transmission module, a wireless transmission module, a flash memory and a control module. The wireless transmission module is wirelessly connected with an external wireless device. The wired transmission module is electrically connected to external wired devices. The control module is electrically connected to the wired transmission module, the wireless transmission module and the flash memory, and the control module receives a data sent by the wired transmission module or the wireless transmission module, and stores the data in the flash memory. A buffer from which data is read and sent to a receiver.

During data transmission, if the external wireless device is controlled to transmit a data, the receiving end is an external wired device, and if the external wired device is controlled to transmit a data, the receiving end is an external wireless device. Without changing the respective transmission conditions of the external wired device and the external wireless device, the communication coordination processor of this creation can cope with the speed difference between the high-speed device and the low-speed device, so as to provide more stable data transmission.

In addition, the flash memory can be set so that when the data stored in the buffer reaches an upper limit, the control module generates a stop transmission signal and transmits it to the wired transmission module or an external wireless device.

In addition, the wireless transmission module adopts a communication protocol which is at least one of Bluetooth, Wireless Local Area Network (WIFI), Zigbee, Near Field Communication (NFC), and Near Field Communication (NFC). The wired transmission module adopts RS232, RS485 or RS422 communication protocol.

Please refer to the system diagram of FIG. 1 , which shows a communication coordination processor 10 , which includes a wireless transmission module 11 , a flash memory 12 , a control module 13 and a wired transmission module 14 . The control module 13 is electrically connected to the wireless The transmission module 11 , the flash memory 12 , and the wired transmission module 14 .

The wireless transmission module 11 is connected to the wireless transmission module 51 of the external wireless device 50 for wirelessly receiving or transmitting a data 511 (as shown in FIG. 2 ). At least one of WIFI, Zigbee, Near Field Communication (NFC), and Near Field Communication (NFC). The wired transmission module 14 has a communication interface, and can use the RS232, RS485 or RS422 communication protocol to be electrically connected to the external wired device 20 .

The control module 13 may be a communication coordination/management microcontroller for controlling data transmission between the external wired device 20 and the external wireless device 50 . In addition, the control module 13 can also be used to manage the capacity of the buffer 121 used by the flash memory 12 to store data.

Please refer to FIGS. 2 and 3 , which illustrate the data transmission process of the communication coordination processor 10 by taking the external wired device 20 receiving the data 511 of the external wireless device 50 as an example. In this embodiment, the wired transmission module 14 of the communication coordination processor 10 is electrically connected to the external wired device 20 .

As shown in FIG. 2 , after the wireless transmission module 11 of the communication coordination processor 10 receives the data 511 , the control module 13 controls to store the acquired data 511 in the buffer 121 of the flash memory 12 , as shown in FIG. 3 , The external wired device 20 reads the data 511 stored in the buffer 121 through the control module 13 .

In this way, the transmission conditions of the external wired device 20 and the external wireless device 50 can perform data transmission without adjustment, and the communication coordination processor 10 responds to the speed difference between the high-speed device and the low-speed device to provide more stable data transmission , to reduce buffer overflow and data loss caused by delay when data is directly transmitted.

In addition, in the era of new technological products, the communication coordination processor 10 can also write various expansion protocols to be applicable to the updated external wired devices 20 or external wireless devices 50, and the old transmission methods can also be upgraded to support more equipment.

In other words, compared with the conventional direct connection between the external wired device 20 and the external wireless device 50 to transmit data, the communication coordinating processor 10 using the present invention has stable transmission, can support various wireless transmission modules, and can be developed flexibly Advantages of mods.

In this embodiment, the storage buffer 121 of the flash memory 12 can set an upper limit value (ie, a safe value) for receiving data. When the capacity of the temporarily stored data reaches the upper limit value, the control module 13 will generate A stop transmission signal 131 is transmitted to the external wireless device 50 , so that the external wireless device 50 stops transmitting data to avoid buffer overflow. If the temporarily stored data capacity does not reach the upper limit, the external wireless device 50 is allowed to continue to transmit data.

It is worth mentioning that when the external wired device 20 transmits data to the external wireless device 50 through the communication coordination processor 10, the external wired device 20 also transmits the data (not shown) to the buffer 121 first, and then the control module 13 controls the wireless transmission The module 11 transmits the data stored in the buffer 121 to the external wireless device 50 to provide more stable data transmission.
