Description

The utility model relates to the field of instrumentation and can be used for automatic control and registration of quality indicators of hot water supply and other utilities.

Decree of the Government of the Russian Federation of 05.06.2011 N 354 (as amended on 02.25.2014) "On the provision of utilities to owners and users of premises in apartment buildings and residential buildings" approved "Rules for the provision of utilities to owners and users of premises in apartment buildings and residential buildings houses "(hereinafter referred to as the" Rules ... ").

In the process of providing hot water and other utilities to an individual consumer (the owner of an apartment in a multi-storey building, the owner of a private house, etc.), there is currently a problem associated with the need to record and document the fact of violation of the quality indicator of the utility service, the duration of the violation, the fact of restoration quality for subsequent recosting. First of all, this applies to hot water supply (DHW).

The problem lies in the complexity of the measurement, registration and documentation processes, requiring the consumer and the service provider to agree on the time of inspections in compliance with the short deadlines from the moment of violation to measurements, to ensure the conditions for taking measurements, and whenever a public service, such as hot water, receives inappropriate quality.

Therefore, the Rules, along with manual one-time measurements, provide for automatic control “... with a meter or other measuring device that is designed for these purposes and is used in accordance with the requirements of the legislation of the Russian Federation on the uniformity of measurements, if these meters and measuring instruments are able to store recorded information” (quote from the "Rules ...", paragraph 111, c).

Known meters of temperature or pressure of water with a record on a paper tape. These are large-sized devices that require frequent qualified maintenance, refueling the tape and recorder (TGS-711M self-recording thermometer, Product catalog of Teplokontrol OJSC, Kazan,). Their use in an apartment or private home ownership is almost impossible.

Known small-sized electronic temperature recorders for liquid temperatures with a memory unit and the ability to read into a personal computer (Datalogger TCTemp1000, MAGETECH (USA); Temperature recorder ZET 7021, Product catalog of ZAO ETMS, Zelenograd,). These devices do not have their own indicator and require the mandatory use of a computer to read and view data, the ability to use it and special software. They are intended for technological measurements, for example, in the food or pharmaceutical industry, or for research purposes.

Also known is a meter-recorder (Measuring instruments-recorders IS-203.2; IS-203.3, Product catalog of LLC TECHNO-AS, Kolomna,), selected as the closest analogue, containing a temperature sensor, other physical quantity sensors that record readings a memory and indication unit that allows data transfer to a computer. One of the purposes of this device is its use in public utilities.

This device, like all the analogs described above, does not functionally provide automatic measurements according to the method defined by the Rules, which indicate that the temperature of hot water is measured after it has been drained for at least 3 minutes (there is no water flow sensor in the device). In addition, it is also structurally poorly applicable in an apartment or private house. The device also does not take into account that the water temperature in the event of its shutdown (significant pressure drop) cannot be measured and registered as incoming hot water (the device continues to measure not water but air). The device also does not take into account that at a low ambient temperature at the place of installation of the water temperature sensor directly into the pipe, for example, when cold air enters the place of the input unit in the room or a violation of the heating of the room as a whole, the measured water temperature will significantly differ from the temperature of the supplied water, those. erroneous registration of a violation of the quality of DHW without taking into account a violation of the measurement conditions will occur.

Thus, the measurement by all the indicated instruments of indicators of the quality of hot water supply of an individual consumer in accordance with the Rules will be functionally impossible, not reliable.

In addition, in order to verify the registered data and enter them into documents for subsequent submission to the services for calculating services, the representative of the service provider (supplier), in particular hot water, must again, at the time agreed with the consumer, read the readings from the indicator of the device installed in the room consumer. That is, for both sides of the process, significant difficulties and inconveniences remain. It will also require quite complicated installation - “insertion” of this registrar into the domestic hot water supply system.

The objective of this utility model is to eliminate the above disadvantages.

The technical result consists in ensuring the functioning of the meter-recorder of hot water quality indicators in full accordance with the methodology of the Rules and the corresponding ensuring the reliability of measuring temperature and pressure and determining their deviations from the norms, as well as in improving the usability with the possibility of remote access to the meter-recorder.

The technical result is achieved by the fact that a hot water temperature sensor, a memory and calculation unit, a display unit, an interface unit for communication with external computer devices, a hot water flow speed sensor, a hot water pressure sensor , an ambient temperature sensor, the outputs of which are connected to the inputs of the memory and computing unit, as well as a unit for generating and transmitting SMS messages and a non-volatile memory unit and ind ikatsii. At the same time, the hot water temperature sensor, the hot water flow rate sensor and the hot water pressure sensor are assembled into one sensor unit, which is installed in the hot water supply system instead of the plug of a standard flat filter for rough water purification and at the same time performs the functions of this plug without violating the functions of the filter itself .

The technical essence of this utility model is illustrated by the following illustrations. Illustration (Fig. 1) depicting a structural diagram of the device. Illustration (Fig. 2), which depicts a preliminary design of the measuring part with a sensor unit mounted in the filter housing, the composition and connection diagram of the electronic units and their approximate design. The numbering of elements and blocks in the illustrations coincide.

The device includes.

A water temperature sensor (1) that measures the temperature of hot water in the DHW pipe at a controlled point in the water;

The sensor (2) of the water flow rate to determine the fact of water discharge, at which, in accordance with the Rules, a temperature should be measured in the DHW pipe;

A water pressure sensor (3) that measures the pressure of the water at the point of drawing relative to atmospheric.

Sensors (1), (2), (3) are structurally integrated into the sensor block and are placed directly in the measuring medium - hot water.

An ambient temperature sensor (4) that measures the air temperature in the immediate vicinity of the hot water measuring point to take into account a possible error in measuring the temperature of hot water when it is supplied to a room with a low air temperature. The sensor (4) is also structurally integrated with the sensors (1), (2), (3), but is located outside the measured medium (hot water).

Sensors (1), (2), (3), (4) are structurally made as a single unit and are mounted in a device that is a plug installed in a standard filter for rough water purification without changing its functions.

The unit (5) of memory and calculations, performing time readings of sensor readings with a given resolution, storing them in memory for a certain time, calculating the indicators and storing the calculated values.

The display unit (6) showing optionally the current values of the indicators, their stored values, calculated indicators.

The block (7) is interface, which provides the device with an external personal computer (PC) or network server.

Block (8) is an SMS signal generator that generates and sends SMS messages about the fact and duration of the violation and the main quantitative characteristics of deviations via mobile communication channels.

Non-volatile memory and indication unit (9) connected to the sensor unit and other units and recording their readings in a separate non-volatile memory and issuing readings on a separate indicator board with independent battery power.

Blocks (5-9) are structurally combined and connected to each other and to sensors by electric cables and connectors.

The device operates as follows.

Sensors (1-4) are continuously measured, and Block (5) records the output signals of all sensors and systematically determines the fact and duration of water use and the fact and duration of the deviation of the DHW quality indicators from the norm in accordance with the "Rules .." method, including including taking into account the time of day (according to internal hours). In particular, according to the readings of the sensor (2) of the water flow rate, block (5) determines that the water has been drained (water consumption) for a certain time, and at the same time it records the measurement of hot water, as well as the fact and duration of the deviation from the norm, if it attended. If water does not drain, measurements are not recorded.

The pressure of hot water by the sensor (3) is measured continuously, but is recorded (with the determination of the fact of a deviation from the norm) with a low water flow or no flow (determined by the flow rate sensor (2)) and taking into account the time of day. This eliminates the erroneous registration of deviations from the norm when the pressure drops at high flow rates.

If the water pressure is close to zero, i.e. the water supply is turned off, then its temperature is not recorded, and only the pressure deviation is recorded.

If the ambient temperature sensor (4) determines that the air temperature in the immediate vicinity of the hot water measuring point is below normal, then the hot water temperature measurement is not recorded, and the fact of violation of the operating conditions is recorded in the device memory.

Block (5) of memory and calculations based on the readings of sensors that have changed over time, the values of this time and the established (recorded in memory) normal values, determines the duration of the service, the facts of violation and restoration of services, as well as the duration of violations or other indicators, the calculation of which is embedded in the program of the calculator, and registers them in memory.

Other sensors of utility indicators, for example, cold water pressure, room temperature, surface temperature of heating systems, room humidity, and others defined by law as a utility service and amenable to automatic measurement, can be connected to the memory and computing unit (5) wirelessly.

The control values (temperature norms, pressure standards, time of day for measurements, etc.) are recorded in block (5) during manufacture in accordance with the norms established by the Rules. However, by agreement of the consumer and the service provider, others can be installed, based on the characteristics of the water supply in a particular house, for example, the drainage time before the measurement is increased, or the time of day for the measurement is changed.

The display unit (6) receives data from the memory and calculation unit (5) and shows optionally the current values of the indicators, their stored values, calculated indicators. It has sound signals included at the request of the consumer, confirming the facts of measuring and determining the violation of the quality of the service.

The interface unit (7) receives data from the memory and computing unit (5) and ensures its transmission to an external personal computer (PC) or network server. In the case of the availability of hardware capabilities and the necessary qualifications from the consumer and the supplier, remote access to the instrument readings can be made through this unit.

Block (8), an SMS-signal shaper via mobile communication channels (when writing mobile numbers to it), based on the data of block (5) of memory and calculations, automatically generates and sends SMS numbers about the fact and duration of the violation and the main quantitative characteristics deviations. Thereby, the requirement of the "Rules ..." is met for the consumer to report a violation by telephone (the consumer is "registered" in the device’s memory).

The non-volatile memory and indication unit (9) is structurally and functionally part of the device, connected to sensors and units and records their readings, but has its own non-volatile memory and its own indicator board with independent battery power. It is electrically and structurally compatible with only one type of devices, and with serial production it is informationally (through coding) compatible with only one device of all, in addition, disconnecting and connecting the unit is possible only after unlocking the mechanical locking device on the connector with a key that is individual for each device in the series .

This unit provides the possibility of full use of the device by any categories of citizens-consumers of services, including those who do not have a personal computer and the Internet in the apartment. The readings from it can be read at the installation site, they duplicate the readings of the display unit (6), but if necessary, you can analyze the readings recorded by him and outdoors (in the office of the contractor, regulatory authorities, etc.). It can be temporarily disabled, it will store and display the recorded data, but then returned for further recording.
