Known small portable cardiograph [1], containing a block of electrodes of standard leads, a switch, a differential amplifier, a block for the allocation of a variable component, an analog-to-digital converter (ADC), a microprocessor controller, a liquid crystal display and providing blocks. The disadvantage of this device is the lack of remote monitoring.

The disadvantage of this apparatus is the design complexity and the possibility of unauthorized access to the system due to the presence of a radio channel and a network computer.

The closest in technical essence is a human operator monitoring system [3], which contains sensors of biological signals, a common electrode and common mode suppression, a bioelectric signal multiplexer, a thermoelectric signal multiplexer, a normalizer amplifier, an ADC of electrobiological signals, a digital-to-analog converter (DAC) of zero correction , ADC of thermoelectric signals, code-voltage converter, control controller, microprogram memory block, random access memory ystvo, biofeedback processor, DAC incentives and tests, normalizer and stimulus tests, the switching unit paraphase signal, serial communication interface, human-operator wireless transceiver, a wireless transceiver device of the computer, a central computer. The disadvantage of this apparatus is the increased complexity of the design and the possibility of unauthorized access to the system due to the presence of a radio channel and a network computer.

The objective of the invention is to simplify the design, increase the individualization of monitoring, reduce the possibility of unauthorized access to the system and provide alarm.

The solution to the problem is achieved by the fact that in the monitoring system of a human operator, which contains a series-connected sensor block, a switch, an interference compensator and an analog-to-digital converter, a digital-to-analog converter, the output of which is connected to another input of the interference compensator, the digital channel and a computer connected in series are connected in series connected unit of an individual memory card and a microprocessor controller, the input of which is connected to the output of an analog-to-digital converter, the output is connected to the input of of an analog-to-analog converter, the control output is connected to the corresponding inputs of the switch and the interference compensator, and the output-input is connected to the corresponding input-output of a digital channel, and the interference compensator is made with the possibility of additionally compensating for network interference, and the sensor unit is made in the form of a set of sensors, each of which consists of an electrode for removing biopotential, combined with an amplifier, and is configured to install standard cardiographic leads in appropriate places.

The technical result consists in simplifying the design, increasing the individual security of monitoring, reducing the possibility of unauthorized access to the system and providing an alarm.

The drawing shows a structural diagram of the system.

The human operator monitoring system comprises a sensor unit 1, a switch 2, an interference compensator 3, an analog-to-digital converter 4, a microprocessor controller 5, an individual memory card block 6, a digital-to-analog converter 7, a digital channel 8 and a computer 9.

The monitoring system of the human operator operates as follows. From the output of the sensor unit 1, the biopotentials obtained at the electrodes and amplified are supplied through the switch 2 and the interference compensator 3 synchronously controlled by the controller 5, and the ADC to the controller 5, which in accordance with the entered program generates a digital signal through the DAC to the interference compensator 3 to compensate for the DC component and network interference of biosignals. An individual memory card 6 containing in the file "read only" the reference data of the processes, the upper and lower boundaries of the processes and the values of the characteristics acceptable for a particular human operator, is used by the controller 5 for ongoing monitoring. In case of violation of these boundaries, the controller 5 sends an alarm signal through digital channel 8 and computer 9 to the central post (CPU) (not shown). The reaction of the head of the CPU is transmitted to the human operator via the return channel and is recorded on an individual memory card 6 in a file of the "write only" type; The results of the current monitoring are recorded in the same file. Changing the file type of an individual card directly in block 6 cannot be made, but is performed outside the operational control time when analyzing the monitoring results when entering the personal password of the human operator.

The human operator monitoring system can be made of standard modules and on an accessible element base. The constructive implementation of a number of blocks may coincide or include designs of the same functional purpose of the prototype and analogues. For example, the designs of the following blocks may coincide with the blocks of the prototype: 2 s 4, 3 s 6, 4 s 7, 7 s 8, 8-9 s 18-21 [3]. The design of the following blocks can coincide with the analog blocks: 1 - with the design of the subsystem of blocks 1-3 analogs [2]; 5 - with 10 [1], and the gating and comparison logic in the software may coincide with [4]; the connection of block 6 - with the connections of block 14 [1]. The implementation of the blocks is determined by their functional purpose and is known or obvious from the prior art in the applicable time and frequency ranges.
