Problems solved by technology
In the case where the single chip microcomputer controls each steering gear individually, due to the large number of steering gears, a large number of wires are required, which expands the space occupied by the wires, resulting in inconvenient installation and maintenance. At the same time, a large number of wires increase the system. The anti-interference ability and reliability of the whole system are reduced
In addition, a large number of wires also increase the size, weight and production cost of the robot

The invention relates to a control circuit for realizing single-line transmission among multiple devices, which comprises a main control unit and a plurality of controlled units, wherein the main control unit is connected with the controlled units respectively through a PWM signal control line; and the main control unit outputs a PWM pulse control signal with adjustable amplitude and frequency to the controlled units. The invention completely changes the traditional multiline control mode and realizes single-line control on multiple electric appliance units in the control system. Since the control line harnesses are reduced, the system fault points are reduced, so that the disturbance-resisting capacity and reliability of the whole control device are greatly enhanced. Meanwhile, the wire material and the occupied space are saved, thereby facilitating the system layout of the control circuit and finally reducing the economic cost.
Description
technical field [0001] The invention relates to the field of electric appliance control, in particular to a control circuit for realizing single-wire transmission between multiple devices. Background technique [0002] When a single-chip microcomputer controls multiple devices, such as in the control of a robot, due to the control of many steering gears, each steering gear needs 3 wires: the power line, the ground wire and the signal line are connected to the single-chip microcomputer. Assuming that there are 5 steering gears in the whole system, 5 steering gears need 7 wires to connect with the microcontroller, among which, 7 wires include 1 power wire, 1 ground wire and 5 signal wires. In the case where the single chip microcomputer controls each steering gear individually, due to the large number of steering gears, a large number of wires are required, which expands the space occupied by the wires, resulting in inconvenient installation and maintenance. At the same time, ...
