RU15528U1 - CONTROLLER OF INPUT-OUTPUT OF ANALOGUE AND DISCRETE SIGNALS - Google Patents

Description

I / O controller of analog and discrete signals.

The proposed utility model of the controller relates to the field of technology for the collection, transmission, processing and display of information necessary for operational centralized control of the processes of production and distribution of electricity. The proposed controller is included in the set of devices that form the control panels of industrial energy facilities, which are used to control objects that are remote from the control center over significant distances through communication channels.

The controller for inputting the output of analog and discrete signals is declared in the form of a functionally connected physical shell - the base, which serves to place on it a set of telemechanics elements assembled and integrated into a single unit for a given purpose.

Known devices for a similar purpose (see Prospectus from Siemens, catalog ST 50 1995. Simatic. Programmable controllers).

The known device consists of a rectangular hollow casing containing microcircuit modules and connectors.

The known device has the following disadvantages: it is enclosed in a rectangular box with a trellised top cover. The back cover has a horizontal longitudinal gutter, in which a plate bolt is installed with the possibility of horizontal movement, which serves to fix the device casing on a common horizontal busbar of the metal frame of the switchboard device. A disadvantage of the known device is a complex system of attachment to the frame, randomly, unsystematically located terminal leads and inputs.

The objective of this utility model is to eliminate the above drawbacks and create a structure in which the housing is best structurally linked to the groups of elements located in it.

This problem is solved in the proposed design of a useful model of an input controller for outputting analog and discrete signals, consisting of a plastic case with a base on which it is fastened in a common control panel, covers with holes for outputting contact and signal parts of the internal element base, as well as an internal printed circuit board with elements of a general circuit solution located on it, in which the rear wall of the base has a continuous longitudinal horizontal recess.

As one embodiment, the base is made longer, protruding below the front cover and does not close with it, moreover, this protruding part of the base on the left and right sides has vertically arranged rows of terminal connectors for connecting sensor networks, as well as corresponding rows of indicator lights. The indicated embodiment is intended for a large number of incoming and outgoing communication lines. In this case, it is advisable that the latch of the lower base be made in the form of a flat rectangular plate equipped with recessed stepped protrusions on the front and side sides, which serve to interact with the grooves of the lower base rib, in the center of the plate has a through window in which there are two figured spring protrusions with the right and left parts of the window, and, in the upper part of the window there is a spring locking protrusion, while these spring elements are designed to interact with the semicircular protrusion of the slot the lower edge of the base, and the latch plate has a hole in the bottom for finger grip.

The indicated expediency allows for easier installation, replacement and repair of the device, if necessary.

The utility model (see Fig. 1,2) consists of a plastic housing 1 with a base 2, on which are located the means of fastening it in a common control panel, from a cover 3 with holes for outputting the contact and signal parts of the internal element base. The rear wall of the base 2 (see FIG. 2) has a continuous longitudinal horizontal recess 4, moreover, its upper rib 5 is provided with horizontal protrusions 6, and the lower rib 7 bounding the recess 4 is provided with a latch 8 (fully shown in Fig. 4, as well as in Fig. 5 and 6), having the ability to move in the grooves 9 made in the lower rib 7. The latch 8 is made in the form of a flat rectangular plate having recessed step ledges 10 on the front and side sides that serve to interact with the grooves 9 of the lower ribs 7 base 2. In the center, the latch 8 has a through window 11 in which two curly spring protrusions 12 are located, protruding inwardly in the right and left parts of the window 11. In the upper part of the window 11 there is a spring locking protrusion 13, said spring protrusions 12 and 13 designed to interact with a semicircular protrusion of the slot of the lower edge of the base 7.

The latch plate 8 has an opening 14 in the lower part for finger grip of the hand, if necessary, to disconnect the base from the common busbar frame busbar 15 (see Figure 4).

The front cover 3 of the housing 2 in its upper part on the left has a terminal block 16 for supplying voltage. Then, to the middle of the cover 3, there is a protrusion 17 with an earth terminal and then on the cover 3 there is a connector 18, which serves to connect an external device and an indicator lamp 19 of the exchange mode .

The middle part of the cover 3 has a longitudinally horizontal, over the entire width, protrusion 20. The protrusion 20 has the form of a rounded roller of positive curvature. In the lower left corner of the protrusion there is a power indicator lamp 21. In the lower part of the cover 3 in its entire width is a horizontal row of terminal connectors 22, used to connect external sensors.

Located in the housing 1 on the base 2, the printed circuit board 23 has, in addition to the elements facing the cover 3, located on the main board 23 on the left side of the chip 24, connectors 25 for connecting additional, upright small printed circuit boards 26 capacitors.

Between the connectors 25 are two vertical rows of microcircuits 24.

The proposed utility model is installed in a common control room and is attached to the tires 15 using the latch 8 (see Fig. 8). For the case when there is a need to input and output a large number of cable connections, for example, discrete and analog sensors, a significant number of peripheral cables, a special embodiment of the device is provided (see Fig. 7), in which the base 2 is made longer, protruding below the front front cover 3, and does not close it. The protruding part of the base 27 on the left and right sides has vertically arranged rows of terminal connectors 28 for connecting sensor networks, as well as rows 29 of corresponding indicator lights.

The controller for inputting the output of analog and discrete signals collects, transfers and processes the information necessary for operational centralized control of the processes of production and distribution of electricity. The proposed controller is included in the set of devices that form the control panels of industrial energy facilities, which are used to control facilities that are remote from the control center over significant distances through communication channels.

In this application for a utility model, only the constructive arrangement of the elements and parts of the controller is claimed and its electrical circuit is not considered.

The utility model is intended for industrial production at the enterprise AOZT Yug-Sistema (Krasnodar). For the manufacture of the controller there are plots of plastic pressing, manufacturing of printed circuit boards, assembly and commissioning workshops, as well as teams of installers and adjusters.

The block body can be made of modern plastics, for example: copolymer, afilonitrile butadiene styrene (ABS), as well as polyethylene.
