The power supply board card 1 comprises three groups of power supply modules which are respectively a first group of power supply modules 1-1, a second group of power supply modules 1-2 and a third group of power supply modules 1-3, wherein the first group of power supply modules 1-1 and the second group of power supply modules 1-2 both provide three types of power supplies, such as +24V power supplies, +12V power supplies and +5V power supplies, the first group of power supply modules 1-1 and the second group of power supply modules 1-2 are used for providing power supplies for the connector, and the third group of power supply modules 1-3 are used for supplying power to the CPU board card, the serial port board card 2 and the CAN board card 3. The primary power supply voltage (+24V) output by the power supply electric box is output to a power supply board card 1 in a universal interface of the central computer electric box in multiple paths (more than 2 paths), the primary power supply on the power supply board card 1 is divided into two parts, one part supplies power to a secondary power supply, and the other part supplies power to an external connector. The power supply on the power supply board card 1 is divided into three groups, namely a first group of power supply modules 1-1, a second group of power supply modules 1-2 and a third group of power supply modules 1-3, each group of power supply modules comprises two isolated DC/DC modules, wherein one isolated DC/DC module is used for converting a +24V power supply into a +12V power supply, and the other isolated DC/DC module is used for converting the +12V power supply into a +5V power supply. The third group of power modules 1-3 supplies power to the CPU board card, the serial port board card 2 and the CAN board card 3. The first and second sets of power modules provide +24V, +12V and +5V power to the external connectors, respectively.
Each connector is respectively connected with each single machine on the air floatation rotary table, each connector connected with the first group of power supply modules 1-1 forms a first group of connectors, and each connector connected with the second group of power supply modules 1-2 forms a second group of connectors. As shown in fig. 2, a schematic diagram of signal relationships between each connector and each board card is shown, and here, only the number of serial ports of the serial port board card 2 is 8 (serial ports 1 to 8) and the number of connectors is 8 for example, where the connector 1, the connector 2, the connector 3, and the connectors form a first group of connectors, and the connector 5, the connector 6, the connector 7, and the connector 8 form a second group of connectors. The +24V power supply, +12V power supply, +5V power supply in the first group of connector is provided by first group power module 1-1 of power supply integrated circuit board 1 respectively, and the +24V power supply, +12V power supply, +5V power supply in the second group connector is provided by second group power module 1-2 of power supply integrated circuit board 1 respectively. Serial port signals in the two groups of connectors are respectively connected with serial ports on the serial port board card 2 one by one, as shown in fig. 2, the connectors 1 to 8 are respectively connected with the serial ports 1 to 8 in a one-to-one correspondence manner.
The serial port board card 2 comprises a plurality of serial ports, and each serial port is connected with a corresponding connector. Preferably, the serial port board card 2 can provide 8 serial ports, each serial port is a multi-protocol serial port, and each serial port can be configured to be any one type of an RS422 protocol, an RS232 protocol and an RS485 protocol according to user requirements. The serial port board card 2 is connected with the CPU board card through an address bus and a data bus, and the CPU board card can control and operate each serial port. If the number of the serial ports is not enough, the number of the serial port boards can be configured according to the number of the single-machine interfaces on the air-floating rotary table so as to meet the requirement of the number of the serial ports.

The four signals are multiplexed signals, and have different functional meanings when configured into different serial port communication protocols. When the CPU board card configures the serial port into the RS422 protocol through an instruction, TX + and TX-are a pair of differential signals at the transmitting end of the serial board card 2, and RX + and RX-are a pair of differential signals at the receiving end of the serial board card 2.
