Description

The utility model is intended for reading readings from metering devices and transmitting, upon request, readings to a data collection network with the possibility of using a radio channel and can be used in Automated systems for commercial metering of energy consumption (ASKUE), in particular, using commercial metering devices with pulse output.

The closest analogue is an object metering and information transmission device containing a microcontroller, including a radio controller, a non-volatile memory unit, an executive unit, (see, for example, http://scht.ru/Tehnicheskaya-informatsiya/Peredacha-informatsii-ot-priborov-ucheta- GKH).

The disadvantages of the closest analogue include the complexity of the design, due to excessive functions.

The technical result of the proposed utility model is to simplify the design.

The technical result is determined by the presence of a cross-board data collection device, a controller including a radio controller, a non-volatile memory unit, an executive unit, outputs for controlling an external device and supplying an element with two pulse inputs located on the cross-board connected to two device inputs, and attached to the executive unit.

The essence of the technical solution is illustrated by the drawing, which shows a structural diagram of a pulse data acquisition device.

The pulsed data acquisition device contains a cross-board 9, a controller 1, including a radio controller 2, two non-volatile memory blocks 3, an executive unit 4, a real-time clock 5, an element 6 with two pulse inputs, a power source 7 connected to the controller 1, an output for control external device 8, two inputs. All blocks are mounted on the cross-board 9. Element 6 is placed on the cross-board 9, connected with its two analog inputs to two inputs of the pulse data acquisition device.

The functions of the main components of a pulsed data acquisition device are as follows.

Controller 1 implements control algorithms. It includes:

- two blocks of non-volatile memory 3, in which executing algorithms and archives with stored information are recorded;

- radio controller 2, providing data transmission and reception over the air, for example, at a frequency of 433 MHz, through an external antenna-feeder device (not shown conditionally in the drawing), matched with the output impedance of radio controller 5;

- Executive unit 4 (processor).

Real-time clock 5 ensures the timely removal of data from the meter and provides their marking in the corresponding archive.

Element 6 with two analog inputs through two inputs of a pulse data acquisition device allows connecting metering devices of the type: dry contact, open collector, NAMUR.

Source 7 autonomous from built-in lithium batteries (with a resource of up to 5 years with a daily survey).

The output for controlling an external device 8 allows to reduce the load (for example, voltage) on external devices.

The operation of the pulse data acquisition device is carried out on the following grounds.

The device is focused on collecting information from current readings of energy metering devices (for example, electricity, thermal energy, hot and cold water, gas) installed on a controlled object, storing it in the archive and then transmitting it on a radio channel.

To transmit the received data from commercial metering devices, a wireless interface is used over the air, for example, at a frequency of 433 MHz.

Also, a pulsed data acquisition device can be used as a repeater for transmitting data received from other similar devices.

Data transmission to the radio channel can be carried out both in accordance with the established algorithm, and at the request of the data collection server from the radio channel. Changing the parameters of the device can be carried out remotely also through a radio channel.

The operating modes of the pulse data acquisition device are passive and active.

In the passive mode of operation, the radio controller 2 is in the off state, which reduces the power consumed by the device. At the same time, the real-time clock 5, the interface circuits, and the counter are in an active state.

The two-channel counter takes into account incoming pulses. The non-volatile memory block 3 of the controller 1 accumulates the readings of commercial meters. At the same time, hourly, daily and monthly archives are allocated.

In passive mode with a given frequency, the radio controller 2 is activated and switches to receive mode. If at this moment in the external network there is an activation radio signal, the pulse data acquisition device is put into active mode. In this mode, in addition to all the functions of the passive mode, the procedures for reading data, correcting or entering the readings of commercial meters, reading or adjusting the real-time clock are also performed 5. At the end of the data recording / reading procedures, the pulse data acquisition device is automatically switched to passive mode.

Also, the device allows the signals from the radio channel to change the load of external devices to control the supply of energy to the consumer.
