Abstract

This device for remote reading of levels of electromechanical electricity meters with LED indication in single-phase AC networks contains a reading head, electronics unit, power supply source, connecting cables. According to the utility model, the reading head is made on the basis of a photoresistor and capable of registering the number of flashes of LED, which is located on the front panel of the meter.

Description

The useful model belongs to devices for remote reading of readings of electromechanical electricity meters in single-phase alternating current networks and can be used in single-phase electromechanical meters with LED indication, in which there is no pulse output, or access to it is limited (in particular, meters of the CO- type

EAOV).

Well-known devices for remote reading of electricity meter readings "Epegdu Uer-

ХВ", which require the presence of a pulse output on the meter, their connection requires unsealing and re-sealing of the meter. This device was chosen as the closest analogue.

The disadvantage of the mentioned device is the need to have a pulse output on the meter, as well as the use of only one means of information transmission (M/I-Ry). The vast majority of meters that are currently used in household electrical networks do not have such an output, and the use of these devices requires the replacement of such meters, which is quite an expensive matter.

The useful model is based on the task of performing the function of remote reading of readings without breaking the design and sealing of the meter, even if there is no pulse output on it.

The task is implemented due to the fact that the reading head is based on a photoresistor and has the ability to register the number of flashes of the LED, which is located on the front panel of the meter. The electronics unit is made with the possibility of transmitting information about the consumed electricity to the server for storage using wireless means of communication.

The device has autonomous power from a direct current power supply unit.

The essence of the useful model is explained by the drawings, where in fig. 1 shows the general view of the proposed device. The device for remote reading of readings of an electromechanical electricity meter with LED indication includes a reading head with a photoresistor 1 installed on the front panel of the meter opposite the "network" LED, an electronics unit 2, which houses a microcontroller board and means of wireless information transmission (for which UMi can be used -Ri, Vineyuoi, S25M, etc.).

Z Cable 3, which connects the reading head to the electronics unit, and 4, which connects the electronics unit to the power supply.

In fig. 2 shows the basic electrical diagram of the device (which includes the electronics unit and RowegWapk). The device for remote reading of readings of an electromechanical electricity meter with LED indication in single-phase alternating current networks works as follows. The lighting of LED 11 "Network", located on the front panel of the counter, is perceived by the photoresistor EB, which forms the corresponding electrical signal, transmits it to the microcontroller board MC, where it is compared with the level of the signal that corresponds to the illumination created by the switched-on LED 1 "Network". If these signals match, the controller gives a command to count the flash and add it to the total number of registered flashes. After that, the microcontroller (Modems) translates the total number of flashes into the counter reading in the number of flashes, which corresponds to one kWh

Next, the meter readings are transmitted to the server 5 for further processing and archiving using means of wireless transmission of readings. In the schematic diagram (Fig. 2), as an option, the UMI-RII EBR8266 module, built into the MSU1 microcontroller board, is used as a means of wireless information transmission. Although, depending on the operating conditions and the wishes of the client, any wireless communication module can be used.

Any cloud storage or your own server can be used as a server.

The device is powered by a 12 V voltage from an autonomous power cell (RozhetgVapk)

Calibration of the device for remote reading of the readings of the electromechanical electricity meter with LED indication is implemented at the software level and consists in experimentally determining the level of illumination on the EVT photoresistor, which corresponds to the start of the flash.
