Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, a novel internet of things communication server includes 10 paths of RS232/RS485 two-in-one serial transceiver, 12 paths of switching value inputs, 4 paths of switching value outputs, 1 path of 10M/100M self-adaptive ethernet, and a 400MHz CPU, where the 10 paths of RS232/RS485 two-in-one serial transceiver, 12 paths of switching value inputs, and 4 paths of switching value outputs are respectively connected with the 400MHz CPU, and the CPU is further connected with the 10M/100M self-adaptive ethernet; in the uplink direction, the CPU respectively packages the data received by the 10 paths of serial ports and the 12 paths of switching value input data, and then sends the data through the 10M/100M self-adaptive Ethernet. In the downlink direction, the CPU receives the 10M/100M self-adaptive Ethernet data packet and transparently sends the original data to the terminal equipment through the corresponding ports of the 10-channel RS232/RS485 two-in-one serial port transceiver and the 4-channel switching value output port; the uplink direction and the downlink direction adopt independent data transmission rates, for example, the data transmission rate in the uplink direction can be 10M/100Mbps, the RS232 data transmission rate in the downlink direction is 115200bps, the RS485 data transmission rate in the downlink direction can reach 460.8kbps, and switching value data is generally triggered according to events and has no specific transmission rate.

In this embodiment, a 10M/100M adaptive ethernet is used, so that the device can be quickly connected to a network, a user can access the terminal device through any position in a local area network or the Internet, and configuration management can be performed through a web browser or a TELNET terminal.

And in the RS232/RS485 two-in-one serial port transceiver, the RS232/RS485 gating is controlled by adopting an enabling mode. For example, a serial port is connected to an RS232 interface serial device, a user configures the serial port into an RS232 through a web browser, a system can Enable an RS232 chip to Enable the chip to work normally, and a Disable RS485 chip closes an RS485 function. Therefore, the cost increase caused by replacing equipment for adapting to different standards can be avoided, and the configuration management is carried out through a web browser or a TELNET terminal, so that the method is simple and convenient. Similarly, the switching value can also be controlled and read data by using a webpage, and can also be directly accessed in a SOCKET port mode, so that the switching value is very convenient to use.

Greatly saving manpower and material resources.

In the RS485 bus, when the transmission distance is longer or the transmission rate is higher, echo interference exists in the line, and in order to eliminate signal reflection, a 120 omega matching resistor is terminated in a communication line; in addition, in order to enable the voltages of the A-B ends of all the nodes to be more than 200mV or 200mV when all the drivers of the circuit release the bus, a pull-up resistor is adopted at the A end, and a pull-down resistor is adopted at the B end, so that stable and reliable output of the bus is ensured when the circuit fault occurs, and the communication quality of the RS485 network is greatly improved.

The RS232/RS485 two-in-one serial port Internet of things communication server with isolation, which is adopted in the embodiment, can not only meet basic RS232 communication, but also guarantee stable and reliable communication when the transmission distance is far away and the interference is large.

Compared with the traditional serial communication equipment, the novel Internet of things communication server has the following advantages:

1. the RS232/RS485 two-in-one device avoids the increase of cost caused by the need of replacing the serial server for different serial devices. In addition, RS232/RS485 can be conveniently selected through the configuration of a web browser or a TELNET terminal, the application range of the device is wider, and the practicability is higher.

2. The remote device can directly get electricity from the port, and power supply processing of the terminal device is simplified. And meanwhile, the working state of the terminal equipment can be optimized.

3. For the field needing switching value control, the device directly integrates the input and output functions of the switching value, and optimizes the scheme of the original independent serial port device and independent switching value networking device. So that the two are combined into one. Therefore, the integration level is improved, the time of wiring construction and the time of software debugging are optimized, and the cost of software and hardware can be saved.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
