Device with automatic adaptation of communication speed function interface

The invention is a design of data transmission, in particular to a device with an automatic adaptation of the communication speed function interface.

With the advancement of the information industry, computers have become an indispensable tool in life and work. Traditionally, data transmission is carried out through the communication interface of Serial Communication, which is used for general communication. The transmission interface includes RS232/RS422/RS485, i2c (Inter Integrated Circuit), SPI (Serial Peripheral Interface), USB, HDMI, and Firewire (1394). The transmission interface or serial transmission interface is only RS232/. RS422/RS485, i2c (Inter Integrated Circuit) and SPI (Serial Peripheral Interface) are used as examples. Therefore, if RS232/RS422/RS485 interfaces are used, the same data transmission and reception interface must be used before communication. The transmission rate, that is, the Baud Rate setting, that is, the same transmission bandwidth (transmission speed), if the baud rate is set incorrectly, the receiving speed of the transmitting end and the receiving end cannot be consistent, and the data cannot be correctly and completely completed. Transmission, or communication.

In addition, when the i2c (Inter Integrated Circuit) transmission interface is used, the two-way data communication is performed by two signal lines, and the problem of the RS232 interface baud rate setting can be solved. However, the i2c interface must communicate in a wired manner. Not suitable for long distance device communication.

Furthermore, when the SPI (Serial Peripheral Interface) is used as the transmission interface, at least one device in the communication process outputs data at the primary end, but there may be multiple slaves receiving data, but the same problem as the i2c transmission interface. Therefore, the distance between the primary end and the secondary end of the SPI interface is short, and four signal lines must be used in operation, and the operation is complicated, and the same is not suitable for long-distance device communication.

Therefore, the object of the present invention is to provide a device with an automatic adaptation communication speed function interface, which can be detected with personal movement, and can be automatically adjusted without setting the transmission bandwidth and speed between the sensor and the server. The communication speed is matched with the data transmission, so that the transmitted data can be maintained within the allowed noise interference value, which increases the versatility and freedom of use.

Accordingly, the present invention provides an apparatus for automatically adapting a communication speed function interface, comprising: a plurality of sensors and at least one server capable of receiving a signal value packet to be transmitted by each of the sensors; wherein the sensor has an encoding a unit, an error step coefficient generating unit, an error crossing value generating unit, and a processing interface connected to the encoding unit, the error step coefficient generating unit, and the error crossing value generating unit; the sensors can be moved by the individual Detecting, at the same time, the data to be transmitted by the sensor can be encoded by the coding unit, and the error step coefficient generating unit can generate an error step coefficient, and the error exceeding value generating unit can generate an error exceeding value and the like; Therefore, the values are integrated into a transmission value through the processing interface, and then converted into a numerical signal packet mode and output. Finally, the signal value packet is calculated by the processing unit, the decoding unit and the computing device of the server, and the value can be restored. The transmission data transmitted by the sensor, so the value signal is encapsulated in the transmission process There is no need to set the transmission bandwidth and speed between the sensor and the server, that is, the communication speed can be automatically adjusted to accept the data transmission, and the degree of freedom of use is further increased; further, the error step coefficient and the error exceeding value are added. It can also be adjusted and modified through the server backtracking, which greatly simplifies the communication equipment and effectively improves the versatility of the device.
