In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

The utility model discloses a preferred embodiment is, an industrial robot control mainboard based on X86 framework, include: the PCIe interface board comprises a core board, a connector, an interface connector, a bridge chip, a PCIe card socket, a universal asynchronous receiver and a universal asynchronous transmitter, wherein the universal asynchronous receiver and the universal asynchronous transmitter are respectively connected with the input end and the output end of the core board, the bridge chip is connected with one end of the core board, the connector is connected with one end of the core board, the interface connector is connected with one end of the bridge chip, the interface connector is connected with the core board through the bridge chip, the PCIe card socket is connected with one end of the core board, the core board is based on an X86 architecture, the voltage input of the core board is 12V +/-5% direct current voltage, the core board is directly installed on a carrier board based on an X86 architecture, the core board has good economy and functionality, and USB2.0 protocol signals are converted into RS422 protocol signals through the bridge chip, so that a user can conveniently access the basic interface of the core board through the connector, the convenience of access to the interface enables a user to design more flexibly using the features of the core board and then to have an abundant external interface by employing a standard interface connector, thereby having a compact and robust design and an external protection mechanism that can be better applied to automotive, railroad and aerospace industry environments.

As shown in fig. 2, the scheme adopted by the circuit is to convert USB2.0 protocol signals into RS422 protocol signals through a bridge chip. The bridge chip FT232H is a single channel USB2.0 to UART chip manufactured by FTDI corporation. FT232H has the following high level functions:

the single-channel USB is converted into a serial port/parallel port, and has various configurations.

The entire USB protocol is handled on-chip without requiring USB specific firmware programming.

USB2.0 high speed (480 Mbits/sec) and full speed (12 Mbits/sec) are compatible.

UART transmit data rates up to 12Mbaud (RS232 data rate is limited by an external level shifter).

The multi-protocol synchronous serial engine (MPSSE) simplifies the synchronous serial protocol (USB to JTAG, I2C, SPI (MASTER) or bit-bang) design.

Configurable I/O drive strength (4,8,12 or 16mA) and slew rate.

Highly integrated designs include 5V to 3.3/+1.8V LDO regulators for VCORE, integrated POR functionality.

Asynchronous serial UART interface option with full hardware handshaking and modem interface signals.

Meanwhile, as shown in fig. 3, the back end of the RS422 circuit adopts MAX3491 to convert a single-ended signal into a differential signal. Compared with the traditional RS422 signal circuit, the anti-interference capability is greatly enhanced due to the fact that the signal circuit is converted into differential transmission. The interference noise has no influence on the logic significance of the signal. In addition, since the coupling magnetic fields between the differential lines and the ground have the same amplitude and are opposite in direction, the coupling magnetic fields cancel each other out, and therefore electromagnetic interference (EMI) is effectively suppressed in transmission.

As shown in fig. 4, the present solution employs PCA9554A for IO port expansion. The input and output of the IO port are controlled through I2C. Meanwhile, each IO port has an interrupt function through the control of the interrupt pin. The circuit of the next figure (figure 4) is added at the rear end of the IO port, and the TS117PTR is adopted for optical coupling isolation, so that the interface is well protected.

The network interface circuit adopts an internet controller I210, which is a single-port compact low-power consumption component supporting GbE design. I210 provides a fully integrated GbE Media Access Control (MAC), physical layer (PHY) port and SGMII/SerDes port that can connect to external PHYs, supporting 10M/100M/1000M transmission speeds. The circuit carries an SPIFLASH, and a user can perform configuration upgrading by burning FLASH. The rear end uses special Ethernet magnetic ring coil and Ethernet socket, meets the requirements of IEC60601-1 3 rd edition (medical and electrical equipment standard), and improves the safety.

According to the embodiment, the receiving of the universal asynchronous receiver and the sending of the universal asynchronous transmitter are both 16 bytes, and the receiving and the universal asynchronous transmitter of the dual-channel universal asynchronous receiver are adopted, so that the core board overhead can be reduced due to the sending and the receiving of the data of the 16 bytes, and the risks of buffer overflow and data loss are reduced to the maximum extent.

According to the above embodiment, the PCIe card socket has one end connected to the USB interface and the PCIe ex1 interface respectively, and by using the micro PCIe card socket, the HDMI interface is equipped with a level shifter having high bandwidth, low power consumption and electrostatic discharge protection because the signals of the USB and PCIe ex1 interfaces are connected to the socket.

In the above applied structure, the model of the core board is TQMx70 EB; the Type of the connector is Type 6; the model of the interface connector is COM Express; the model of the bridge chip is FT 232H; the model of the universal asynchronous receiver is UART; the model of the universal asynchronous transmitter is UART.

The above description is only for the preferred embodiment of the present invention, and the structure is not limited to the above-mentioned shape, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
