The device operates as follows.

Emerging electromagnetic interference caused by the reasons described above, induced mainly on having the greatest length of the communication lines of sensors 1, 2, 3 with integrators converters 4 and 5 with a block of 6 dimensions and units 8 comparison. However, because these lines are sequentially enabled gazoraspredelitel 20 and the suppressor 21 and, accordingly, gazoraspredelitel 18 and suppressor 19, the energy of the interference is suppressed in two stages. High-frequency conductive noise with amplitude above 3 kV extinguished gazoraspredeleniye. The remaining energy is the interference caused by aperiodic and oscillatory processes, neutralized with a suppressor. The voltage suppressor is selected such that when the interference level exceeding the supply voltage by 20 percent, is the operation of the suppressor (decrease their resistance in a very short time of the order of 1 ns), and the suppression of energy impulse noise. After the suppression of the energy of the interference suppressor is restored (returned to its original state), and the signal transmission from the sensors 1, 2, 3 to unit 4 is in operation. Thus, blocks 6, 8, 9, 11, 12, the most sensitive to electromagnetic interference, electromagnetic interference reaches a safe level, virtually no offset�and thereafter the supply voltage of the device.

Integrators 4 contain analog-to-digital converters that are specified intervals provide measurements coming from the sensors signal and converting it into a discrete code (digital signal), and then averaging the readings over a specified time interval, thus improving the accuracy of measurements. Next, the digital signal is encoded by the transducer 5 into a format that can transmit the signal on a standard asynchronous interface. In this case the digital signal from each sensor is added, a unique identifying number.

Converters 5 transmit the converted values on the unit 6 measurement and units 8 comparison. Referencing-7 contain the maximum allowable value of each of the measured parameters. Everyone entering the block 8 comparison signal is compared with the value contained in the corresponding Adjuster 7. In the reference 7 contains a signal characterizing the maximum allowable level of the measured indicator that allows you to capture all the moments of exceeding the indicator of each of the sensors 1, 2, 3. Unit 8 comparison as Converter 5, a signal to the unit 6 measurement. Unit 6 measure all the parameter values from sensors 1, 2, 3 are transmitted to a block 9 of the pairing, which transmits the measurement values to the control unit 12 and communication - d�I storage in memory and transmission via communication lines to the block 17 I / o. The control unit modes 11 through the block 17 I / o specifies the modes of measurements and their frequency. Additional source 14 power creates energy stored in the buffer 15 of a food and provides a non-volatile memory 16 with the necessary energy for emergency saving measured values. The monitor 13 monitors the power status of the battery of the main unit 10 of the power supply, additional battery source 14 power and buffer 15 power and transmits this information through the control unit 12 and the communication unit 17 input / enter. After receipt of a signal of malnutrition on the power unit 10, a monitor 13 power generates the control signal for the block 11 control modes. Once the control signal is supplied to the input unit 11 of the control modes, the buffer 15 power supports the functionality of the unit 12 of the control and communications unit 16 of the nonvolatile memory unit 17 of the I / o unit 11 of the control modes during the time of capacitor discharge. Information about malnutrition is output to the block 17 I / o.
