Abstract

The invention relates to a serial port communication drive circuit of an industrial robot teaching control circuit, comprising an isolating power supply, an interface I, an interface II, and a chip. A second pin and a third pin of the interface I are respectively connected with a first resistor and a third resistor. A second pin and a third pin of the interface II are respectively connected with a second resistor and a fourth resistor. A tenth pin of the chip is connected with a ferrite bead I, and the ferrite bead I is connected with the first resistor. A ninth pin of the chip is connected with a ferrite bead II, and the ferrite bead II is connected with the second resistor. An eighth pin of the chip is connected with a ferrite bead III, and the ferrite bead III is connected with the third resistor. A seventh pin of the chip is connected with a ferrite bead IV, and the ferrite bead IV is connected with the fourth resistor. The serial port communication drive circuit of the invention has the advantages of reasonable structure design, high control precision, strong anti-interference ability, and the like. The influence of electromagnetic interference, surge and over-current can be eliminated, and interference can be isolated outside an external microprocessor.

Description

Technical field [0001] The invention relates to the technical field of industrial robot control, in particular to a serial port communication drive circuit of an industrial robot teaching control circuit. Background technique [0002] The industrial robot teaching control circuit needs to use serial port communication when debugging. Generally, the serial port RS232 signal or RS485 signal is used. Due to the complex situation of the industrial site, strong electromagnetic interference sometimes occurs. If electromagnetic interference occurs during the communication process, it will seriously affect the accuracy of robot debugging, and the serious situation will cause the robot to malfunction and cause industrial accidents. Therefore, reducing or eliminating electromagnetic interference, improving the accuracy of serial communication, and avoiding unnecessary industrial accidents are of great significance and urgently need to be resolved. Summary of the invention [0003] In order...
