The invention relates to a signal transmission circuit, which mainly comprises an isolation unit, an adjustment unit and a drive unit. The isolation unit is provided with a first input end, a second input end and an output end, wherein an inputted signal is received by the first input end and the second input end, and after the noise is isolated, the signal is transmitted to the output end. The adjustment end is provided with a capacitor, a resistor and a buffering element, wherein the output end of the isolation unit is connected with an anode end of the capacitor through the resistor in serial, the buffering element is provided with an input end and output end, and the input end of the buffering element is electrically connected with the output end of the isolation unit. The drive unit is provided with an input end, a first output end and a second output end, wherein the input end is electrically connected with the output end of the buffering element of the adjustment unit, and the first output end and the second output end outputs an outputted signal.
Description
technical field [0001] The invention relates to a signal transmission circuit, in particular to a signal transmission circuit applied in a control system of a laser device. Background technique [0002] With the development of science and technology, laser (LASER) has been used in medical, photoelectric and automation equipment to achieve various functions that can be achieved by laser, such as treatment, cutting, positioning, etching or inspection. However, each laser device needs to be equipped with a specific control system in order to effectively and stably excite the required laser light. [0003] By the way, the laser device and its control system are obtained from the original factory that manufactured the laser device. If the user needs to modify the control method in the application, the original factory must also provide support, which is expensive and time-sensitive. Therefore, if the user can replace the control system with an equivalent control system, the abov...
