Problems solved by technology

However, at this stage, a central monitoring host can monitor multiple sets of control systems with two control protocols in real time at the same time, and the host addresses are prone to conflicts.
Therefore, some old control system devices that only support RS232 and the RS485 bus system widely used in industry cannot realize monitoring with a TPC1063K industrial computer.
If the method of increasing the working platform is used to realize simultaneous monitoring, it will not only increase the cost of the host hardware, but also increase the labor cost, thus consuming more investment costs as a whole

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, a RS232 / RS485 monitoring system based on the COM serial port of TPC1063K industrial computer includes TPC1063K industrial computer, PC, RS232 control subsystem and RS485 control subsystem. The TPC1063K industrial computer is connected to PC through USB / Ethernet, The TPC1063K industrial computer is respectively connected with the RS232 control subsystem and the RS485 control subsystem through the COM serial port.

[0021] The COM serial port is a 9-pin RS232 / RS485 serial port, the communication protocol of 2 pins, 3 pins and 5 pins is set as RS232 communication protocol, and the communication protocol of 7 pins and 8 pins is set as RS485 communication protocol. The RS232 control subsystem includes a first PLC, a first frequency converter, and a first AC motor connected in sequence, and the first PLC is connec...

Abstract

The invention relates to a RS232 / RS485 monitoring system based on a COM (Component Object Model) serial port of a TPC1063K industrial personal computer, and the monitoring system comprises a TPC1063K industrial personal computer, a PC (Personal Computer), a RS232 control subsystem and a RS485 control subsystem, wherein the TPC1063K industrial personal computer is connected with the PC through USB / Ethernet, and the TPC1063K industrial personal computer is respectively connected with the RS232 control subsystem and the RS485 control subsystem through COM serial ports. Compared with the prior art, the RS232 / RS485 monitoring system provided by the invention has the advantages of simpleness, practicability and the capability of saving the cost and is easy to operate, and the like.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an RS232 / RS485 monitoring system based on a COM serial port of a TPC1063K industrial computer. Background technique [0002] Kunlun Tongtai TPC1062K touch screen TPC1063K industrial computer has a 9-pin COM serial port compatible with RS485 bus protocol and RS232 communication protocol. Each system can be connected to multiple equipment terminals. But at the present stage, a central monitoring host realizes the real-time monitoring of multiple sets of control systems of the two control protocols at the same time, and the host address is prone to conflict. Therefore, some old control system devices that only support RS232 and RS485 bus systems that are widely used in industry cannot be monitored by a TPC1063K industrial computer. If the method of adding working platforms is adopted to realize simultaneous monitoring, not only the hardware cost of the host computer is increased, but also the...
