Specific embodiment
In order to make the attainable technical effect of technological means of the invention and its institute, more perfect exposure can be become apparent from,
One embodiment is hereby provided, and is described in detail as follows in conjunction with attached drawing:
A kind of RJ11 of embodiment 1 turns RJ45 converter, including interface conversion chip, as illustrated in fig. 1 and 2, and with the interface
RJ11 interface, RJ45 interface, RS232 interface, RS485 interface, RS422 interface, power interface and the USB of conversion chip electrical connection
Interface.The number of the RJ11 interface and RJ45 interface be it is N number of, wherein N is positive integer more than or equal to 3.
The converter further includes solid-state relay array, the solid-state relay array by relay drive circuit with
MCU connection；The solid-state relay array is arranged between RJ11 interface and the channel of RJ45 interface.The solid-state relay battle array
The number of column is identical as the number of RJ11 interface and RJ45 interface.Each solid-state relay array is by 4 solid-state relays
Composition.The power interface be input+12V power supply, be converted to+5V and+3.3V through power conversion chip, for entire converter into
Row power supply.
Wherein, the interface conversion chip is MCU.MCU is STM32F105RCT6, is encapsulated for LQFP64, removes USB, supplies
Electricity, 3 serial ports and other ports use, and 8 road RJ11 is at least supported to turn RJ45.If necessary to more multichannel, pin can choose
It is used in parallel that the more MCU or multiple RJ11 of number turn RJ45 converter.
MCU can be upper to receive by any of USB interface, RS232 interface, RS485 interface, RS422 interface
Then machine control command controls the opening and closing of solid-state relay array by driving relay drive circuit to realize letter
Number transmitting and conversion.Each solid-state relay device array can support 16 kinds of RJ11 to turn the combination of the PIN group of RJ45.Specific ginseng
According to shown in Fig. 3.
Specifically, RJ45 includes 8PIN, and 2PIN is one group, can be divided into 4 groups；The telephone signal (2PIN) of RJ11 input is defeated
Out in the different PIN groups into RJ45, which may be implemented the switching that RJ11 turns RJ45 difference PIN group or multiple PIN groups.
Wherein switching mode shares 16 kinds of combinations.Multichannel principle is identical, and is relatively independent；The above-mentioned single channel relay battle array of multicopy
Column.
Wherein, host computer can be one of windows platform, Linux platform, Android platform or MAC system or
Multiple combinations.USB interface, RS232 interface, RS485 interface, RS422 interface can pass through USB port (USB or USB turns
Serial ports) etc. equipment connection host and RJ11 turn RJ45 converter, the systems such as Windows, Linux, IOS can identify commonly
USB turns serial equipment.
Perhaps script command by USB port or USB turns serial equipment to the upper computer software operated in PC system
Order is handed down to the converter by (USB RS 232, USB turn RS485, USB and turn RS422), and converter is according to command parameter, control
The RJ11 of corresponding channel processed turns the switching of RJ45 difference PIN group or multiple PIN groups.
Since RS232, RS485, RS422 etc. industrially can achieve the even upper km of rice up to a hundred, therefore the controller can be with
Realizing remotely has line traffic control.
The controller has the function of serial ports parameter adaptive, specifically, can turn virtual by USB interface software realization USB
Serial port function realizes that USB turns adaptive, the host computer serial port setting of virtual serial port baud rate, data bit, stop position, check bit
Communication can be realized at the serial ports parameter type that MCU is supported.
Since each solid-state relay array can support 16 kinds of RJ11 to turn the combination of the PIN group of RJ45, user can root
According to being selected.
