Description

The invention relates to electronics, in particular, for collecting and processing data from electric energy and power meters and can be used to transfer accumulated and calculated data via communication channels to a data collection center.

A device for collecting and transmitting data is known, consisting of an industrial building, inside of which there is a motherboard of a central processor with non-volatile memory installed on it (see. New solutions of USPD-RTU-325, g. Measurement. RU, No. 6, December 2002, p .21).

The disadvantage of this device is the complexity of installation and increased complexity when reconfiguring and changing the design of the ASKUE.

The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is the controller of data collection and transmission KSD-01-166, which is part of the hardware-software complex "Potok-1"; This controller is a single-board device and consists of a case inside which there is a processor board (see the “Potok 1” hardware-software complex. TU 4222-002-00104900-96. OAO NPK “Electric Technologies”. 355029, Stavropol, Mira St., 448).

The disadvantages of the selected prototype are poor maintainability, the complexity of diagnosing faults, the inability to use the functional expansion.

The technical result, which can be obtained using the proposed device for collecting and transmitting data, reduces universality, configuration flexibility, high maintainability with the advantages of single-board structures, manufacturability, low cost of production.

The technical result is achieved using a device for collecting and transmitting data, comprising a housing with a protective translucent cover and a separate cross compartment lid, while a measuring unit, a cross-board, replaceable modules and a secondary power supply module are installed inside the housing, while the device is equipped with additional input elements located in the lower part of the housing, and the measuring unit is installed in front of the device under a translucent cover on the swivel bracket, moreover, the unit made in the form of a complete functional unit installed in the housing, representing the measuring part of the device, inside which is located the motherboard of the central processor, and on the front side of the unit there is an LCD alphanumeric display, indicator lights of the input channels, IrDA interface, interface connectors and keyboard, and Under the cover of the cross-section compartment there are blocks of clamps for switching external circuits using cables and wires through cable sleeves.

The technical result is achieved by the original location of the measuring unit in the front of the device under a translucent cover on the swivel bracket, which allows quick access to replaceable modules and the module of the secondary power source.

Figure 1 shows a General view of a device for collecting and transmitting data (USPD), from the front side and side view.

Figure 2 shows the relative position of the measuring unit, replaceable modules, secondary power supply module, cross-board.

The device for collecting and transmitting data has a block-modular design, made in a single construct, designed for wall mounting, and consists of a housing 1 with a protective translucent cover 2 and a separate cover 3 of the cross compartment, under which there are clamp blocks 4 for connecting external circuits using cables and drives (not shown in Fig.) through cable sleeves 5, which provides the necessary level of protection against dust and moisture, in the lower part of the housing 1 are additional input ele cients 6, on which are arranged connectors 7 interface (RS 485) and interface connectors 8 (RS 232). Inside the housing 1, in the front part, a measuring unit 9 is installed in the form of a complete functional unit representing the measuring part of the device, fixed with a swivel bracket 10, the latter provides a possible rotation of the measuring unit 9 by 120 ° around the axis of the swivel bracket 10 and thereby provides authorized access with the purpose of repair, enhancement of functional capabilities or reconfiguration of the device depending on the connection scheme of an automated system (not shown), unit measuring 9 is made in the form of a complete functional unit installed in the case (not numbered), representing the measuring part of the device, inside which there is a central processor board (not shown), while the case provides protection against unauthorized access to the board of the measuring unit 9. On the front to the side of the housing of the measuring unit 9 is the keyboard 11, because the housing 1 is made with a protective translucent cover 2, then on the front side of the housing of the measuring unit 9, a liquid crystal alphanumeric display 12, indicator lights 13 of the input channels and interface elements 14 (IrDA) are visible. The measuring unit 9 by means of a flexible ribbon cable 15 is connected to the cross-board 16, on which are located the terminal blocks 4 for switching external circuits and connectors 17 for installing additional plug-in modules 18 for expanding the functionality and module 19 of the secondary power source.

A device for collecting and transmitting data works as follows.

Electrical impulses from electric energy meters through cables (not shown in Fig.) Through cable sleeves 5 and terminal blocks 4 are fed to cross-board 16, with which, through a flexible ribbon cable 15, the pulses go to the board of measuring unit 9, in which the received electrical impulses in consumed electrical energy and power. In addition to calculating the energy parameters, the measuring unit 9 accumulates and stores the calculated parameters at time intervals. Using the keyboard 11 and the liquid crystal alphanumeric display 12, the operator views the accumulated and calculated data. In addition to the liquid crystal alphanumeric display 12, the operator monitors the operation of the input channels using the light indicators 13 and collects the received information on a laptop computer (not shown) through interface 14 (IrDA) and then viewing it on a laptop computer or other computing devices. The power supply of the measuring unit 9 and additional modules is provided from the secondary power supply unit 19, the backup power supply (not shown) installed in the measuring unit 9 ensures the storage of operational data in the absence of main power from the secondary power supply unit 19. Monitoring and transmitting the collected information to other devices of the automated system (not shown) is carried out using interfaces 7 (RS 485) and 8 (RS 232), the connectors of which are located at the bottom of the additional input elements 6. The external arrangement of the connectors of the interfaces 7, 8 provides quick connecting and connecting the device to an automated system and thereby prompt collection and monitoring of consumed electric energy at various levels of service. The USPD design allows you to quickly increase functionality, so if you need to increase the connection of additional meters or the need to connect the USPD to the local network, additional plug-in modules 18 for expanding the functionality can be quickly installed.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- high maintainability due to its block-modular construction;

- universality;

- configuration flexibility;

- manufacturability;

- low cost of production;

- increasing the functionality or reconfiguration of the device depending on the connection scheme of the automated system.
