The invention relates to automation and computer technology and can be used in constructing control units for household radio equipment, in particular electronic games, digital electronic clock tuners for broadcast receivers of tape recorders, for inputting, for example, control commands to a microprocessor control unit for a product.

The aim of the invention is to expand the field of application of the device.

FIG. 1 shows a functional diagram of the device; in fig. 2 - an example implementation of a multiplexer and analog-to-digital converter.

The device contains multiplex

The technical solution of the functional sensors 6 must be combined with

The presence at the jth output of a single logic level at the time of its appearance at the i-M input of the device is clearly perceived as a sign of the input information corresponding to the switching element 3-i / j of the matrix 3 excited by the operator.

In the process of polling the matrix 3 (for the presence of a closed switching element), the information inputs of the device receive the position code address.a polling the state of the functional sensors 6-i.

In accordance with the set address, multiplexer 1 connects to the input of analog-digital converter 2 of the corresponding functional, sensor 6.

The degree of force applied by the operator to the functional sensor 6 is transformed into a proportional one; a full change in the electrical parameter, the value of which through the open channel of multiplexer 1 goes to the analog-to-digital converter 2. At the output of the latter, a digital code is generated.

the technical solution of analog-digital-30 is proportional to the effort of the operator.

The transducer 2. As functional sensors 6, mechanical force transducers can be used — an electrical parameter (for example, conductivity, resistance, capacitance, etc.). Proceeding from the existence of a single logical level at the specified output (even if there are single logical levels at all other or part of the device outputs) together with the set one. at the information inputs, the address is unambiguously perceived by the control device as a result of the operator’s excitation of a specific functional40

The existing analog-to-digital converters 2 predominantly of the functional sensor 6 may be a converter-force. - conductivity or force - resistance.

In the process of polling matrix 3, the device generates the sign of the input (command) entered by the operator, corresponding to the air sensor. At the same time, the device that is entered (pressed) by the control operator enters a sign for one or another switching element information corresponding to the given cop of the matrix 3.

When the operator triggers (pressed) the 3-i / j element located at the intersection of the i-th column with the j-th row (where), at the moment when the device’s single logical level arrives at the i-th input, the last through the corresponding dividing element 5 ,

functional sensor 6. The quantitative value (i.e. level) of this 5Q information is determined by the size of the digital code supplied to the low-order outputs of the device from the output of the analog-digital converter 2. Thus, the presence of a single

At a zero code value at the output of the analog-to-digital converter 2, the unit logic level from the output of the OR element is output to the high-order output of the device.

The presence on the specified output of a single logical level (even if there are single logical levels on all others or part of the device outputs) together with the set one. on the information inputs, the address is clearly perceived by the control device as a result of the operator’s excitation of a specific functional

foot sensor. In this case, the control unit inputs the attribute information corresponding to the

foot sensor. In this case, the control unit inputs the attribute information corresponding to the

the functional sensor 6. The quantitative value (i.e. level) of this information is determined by the value of the digital code supplied to the low-order outputs of the device from the output of the analog-to-digital converter 2. Thus, the presence of a single
