Implementation of the utility model.

The device for remote monitoring and control of the temperature at the facility consists of interconnected units for data acquisition 1, data analysis 2, control 3 and information storage 4. , one primary sensor 6, made in the form of a digital temperature sensor.

A data exchange unit 5 is connected to the output of the control unit 3, to which at least one relay 7 is connected. An actuator 8 is connected to the control contacts of the relay 7, for example, a dimmer, a valve, a drive, a triac optocoupler, etc.

An interface module 10, made, for example, in the form of a desktop computer, laptop, tablet, smartphone, etc., is connected to the information storage module 4 using wireless data transmission technology.

The method of remote monitoring and control of the temperature at the facility is used as follows.

Initially, directly in the data analysis unit 2 or with the help of the interface module 9 through the information storage unit 4, the temperature value Tset necessary to maintain the object and the allowable temperature deviation threshold from the set value ΔΤ are set. The primary sensors 6, mounted on the controlled object, at the time ti measure the temperature Ti and through the data exchange unit 5 transmit the measured temperature values Ti to the data acquisition unit 1. The data analysis unit 2 requests the current information about the Ti values from the data acquisition unit 1 and compares the value of Ti with the values of Тzad±ΔТ. Next, the data analysis unit 2 requests statistical data from the information storage unit 4 about a similar or close to the current change in temperature values Ti. Analyzed in the data analysis unit 2 obtained using the primary sensors 6 information about the temperature Ti and statistical data and build a forecast of further changes in temperature Τn in the period Δt=tn-ti. In the case of a predictable approach of temperature Τn to the threshold limits Tset±ΔT, a control signal is sent from the data analysis unit 2 to the control unit 3 and through the data exchange unit 5 and relay 7 to the actuator 8, made, for example, in the form of a power change device by the electrical part of the system heating system (dimmer) or a triac optocoupler that turns off (turns on) the heating or ventilation and air conditioning system, or the valve (drive) of the circulation pump of the heating system, or the drive of the windows (doors) and change the positions of the actuators 8 so that the current temperature value Τ increased or decreased without going beyond the threshold limits Tset±ΔT, after which the measured data, comparison and prediction data are recorded in the information storage unit 4.

To control the operation of the device and the state of the object, the user connects the interface module 9, for example, a laptop, tablet, smartphone, to the information storage unit 4, views the parameters Τ measured by the primary sensors 6 and information about the position of the actuators 8, as well as the statistics of the operation of the remote control device and object control and, if necessary, sets new values of Tset and ΔΤ.

EFFECT: increasing the dynamism of the temperature control system at the facility is achieved due to the possibility of monitoring the temperature values Ti at the time ti, comparing the measured values Ti with a given temperature Tset, taking into account the allowable deviation threshold ΔΤ, comparing a number of measured values Ti in the time period Δt= tn-ti with statistical data, further prediction of temperature changes Τ and early change of actuators 8 connected to the control system and providing the temperature regime of the object in order to maintain temperature Τ within Tset ± ΔT.
