Abstract

The purpose of the invention is to sense continuous signals from an arbitrary number of locations and transfer them to a single location. The stated purpose is achieved by concentrating all sensor outputs on a single electronic element with multiple inputs and a single output, which enables the transfer of signals from individual inputs to the output using a decoder from the BCD code to one of n.

Description

221176

The invention relates to a circuit for multiplexing analog signals. With the development of robotics in different areas of production, the demands of a multiplicity of information that make the robot's intelligence increasing. This consists, for example, in the ability of the robot to orient itself in space, in the ability to identify simple root patterns and bodies, and to perform specified tasks based on the information signals obtained. The information signals are provided to the control computer system by the tactile sensors located in the clamp jaws of the gripper. Tactile sensors for identifying patterns and bodies comprising a plurality of position sensing elements arranged in a matrix such as four lines and patch columns, which represent a set of elements. Such matrices are two-to-one, which is up to forty elements. Information from each sensor element is equally important, so all signals from them must be amplified and standardized so that their dimension of tension is in relation to the position of the position. All these analog signals would have to be brought to the specific inputs of the control computer that would evaluate them at the same time or sequentially. Such a solution would be the function of the controller. computerabola very limited. In addition, the incorporation of amplification and signaling circuits would be both costly and space-consuming.

The aforementioned drawbacks are eliminated by the multiplex analogue signal transmission circuit of the invention, the principle of which is that the outputs of the analogue sensors are connected to one of the inputs of the analogue signal transmission members whose outputs are connected to the output bus. The output bus is connected to the input of the analog signaling member, the output of which is connected to one of the inputs of the sampling element of the analog signals. Secondly, the inputs of the controlled transfer signals are connected to the outputs of the switching members whose inputs are connected to the outputs of the decoder from the BCD code from one. The outputs of the encoder and the output of the control member are connected to the inputs of the decoder from the BCD code. one of the pulse counter inputs, the second input of which is connected to the pulse shaping circuit output which is also coupled to the pulse sampling member input. The output of the constant voltage generator is connected to the input bus connected both to the input of the pulse circuit and to the input of the analogue sensors. One output of the decoder from the BCD code to one of n is connected to one input of the controller, to whose second input the output from the control computer is connected. The output of the sample pulse member is connected to the input of the sample member of the analog signals and one input of the control computer to which the output of the sample member of the analog signals is connected.

By connecting to multiplex the analog signals, amplification and propagation of signals from each sensor element is achieved such that their voltage is in relation to the position dimension. It is also advantageous that all signals are sent to the control computer with only one input, as a result of which signals from other devices can be fed to other inputs of the control computer, thereby significantly increasing the efficiency of the control computer.

In the accompanying drawing, an exemplary on-line block diagram for multicast transmission of analog signals is shown.
