Description

The utility model relates to the field of electrical engineering, and in particular, to control panels for drives of hoisting mast devices (PMU).

Currently, when designing specialized control panels, the practice of creating remote control panels is widely used, taking into account the convenience of the operator. When designing remote control panels, the used electronic radio products (ERI) are quite well known in the art. Therefore, the task of introducing such ERPs into the control panel, in a certain aggregate, is particularly relevant, which will significantly improve operational characteristics, namely:

- reliability of drive control equipment;

- automation of the folding / deployment process;

- safety of operations.

Most of the known analogues of remote control panels are made using the same technology. For example, a remote control panel [1]. It has a standard shape and consists of a housing, cable and controls. This analogue has the following disadvantages:

- lack of protection against erroneous operator actions;

- buttons do not have protection to prevent accidental pressing.

The closest known analogues serving as a prototype of the claimed control panel is a remote control panel for lifting devices [2], shown in FIG. 1. It consists of a casing, cable and pressure controls. The cable is rigidly connected to the console body and has a certain standard length.

The disadvantages of this prototype are the same as the above analogue [1].

In the claimed solution of the remote control panel drive PMU to grant a patent for a utility model, all the above disadvantages are taken into account. The objective of the proposed technical solution is to create a control panel with increased operational reliability, operator comfort and protection against unauthorized control.

The technical result achieved by the utility model is to provide protection against unauthorized control and erroneous actions of the remote control operator.

The specified technical result is achieved by the fact that in the known device, consisting of the main composite elements, such as the housing, cable and pressure controls, additionally introduced display elements, niches in the upper part of the housing and a microcontroller.

The original implementation of the software of the microcontroller, which is part of the remote control, provides mast control, functional control of the remote control, as well as protection from the so-called “human factor”.

In FIG. 2 shows a front panel view of the proposed remote control.

In FIG. 3 is a side view for explaining that the console body consists of an upper part of the housing 1 and a lower part of the housing 2.

Consider the composition and operation of this control panel drive PMU.

In FIG. 4 presents a General view of the proposed device, where indicated:

1 - the upper part of the body;

2 - the lower part of the body;

3 - toggle switch FOLD / DEPLOY;

4 - toggle switch TILT PMU;

5 - display organs;

6 - mount.

For simplicity, FIG. 2, 3, 4, only the control panel case itself is presented without a cable.

Structurally, the remote control panel of the PMU drive consists of the upper part of the housing 1 and the lower part of the housing 2 (Fig. 3, 4).

The upper part of the housing 1 is a panel with controls and displays. The control of the modes is provided with the help of two toggle switches 3 and 4 in three positions, with fixation in the middle position. The display authorities provide an indication of the horizontal position of the platform (VERTICAL 5 indicator), an indication of exceeding the maximum permissible values of longitudinal and transverse rolls (EXTENDED ROCK 5 indicator), indication of the platform extreme positions (EXTREME POSITION indicator 5), as well as an indication of the transport (TRANSPORT indicator 5) and the expanded position of the mast (PMU indicator UNLOCKED 5).

Remote control drive PMU works as follows.

Tilt angle sensors are installed on the platform and mast. Information from the sensors enters the control panel. Based on the signals received from the angle sensor located on the mast, the microcontroller receives information about the longitudinal and transverse roll of the carrier. A sensor mounted on the platform detects the position of the tilt angle.

If any of the rolls is exceeded, the EXPLANATION OF THE ROLL 5. Indicates that the mast cannot be deployed. To deploy the mast, in this case, the carrier needs to change the deployment location. The value of the limiting rolls are set at the stage of the technical specification and their change at the manufacturing stage is possible.

When holding the TURNER / DEPLOY switch 3 in the DEPLOY position, a command is issued to raise the PMP. The process continues as long as the toggle switch is held, or until the extreme position is reached, as indicated by the corresponding indicator (the PMA indicator is EXPANDED 5).

When the PMU reaches the required height, the next stage of the deployment of the antenna system begins. Holding the switch TILT PMU 4 in the UP position sets the upper platform in a horizontal position. When the platform reaches a horizontal position, the installation process stops and the VERTICAL 5 indicator lights up on the remote control. Further tilting of the platform is possible only by holding the toggle switch again. At the same time, the VERTICAL 5 indicator lights out and, when the end position is reached, the EXTREME POSITION 5 indicator lights up.

The PMU folding process begins when the COLLECTION / DEPLOY 3 switch is held in the DROP position. At the same time, the platform is first brought to its extreme position (the EXTREME POSITION 5 indicator lights up), then the mast is lowered to the transport position (the TRANSPORT 5 indicator is highlighted on the remote control). The COLLECTION / DEPLOY switch 3 in the DROP position is not released. Such a process is necessary for the rapid folding of PMU.

Perhaps phased folding PMU. To do this, first hold down the TILT PMU 4 toggle switch in the DOWN position (until the EXTREME POSITION 5 indicator lights up), then lower the mast to the transport position by holding the FOLD / EXPLOIT 3 switch in the FOLD position. This coagulation process is used when necessary to change the height of the lifting platform.

Holding the toggle switches in the appropriate position provides a “presence effect”, i.e. in any process, an operator is present.

Tumblers from unauthorized pressing are recessed into the niches of the upper part of the housing 1. The tumblers are fitted with sealed protective rubber caps that fit snugly against the housing, which eliminates the ingress of moisture and dirt into the console.

The lower part of the casing 2 is a rubber-lined rectangular cover that fits snugly and is screwed to the upper part of the casing 1 (Fig. 3, 4), which ensures splash protection of the remote control casing. The place for holding the remote control in the hand of the upper part of the housing 1 is covered with rubber, which serves to fix and minimize the sliding of the control panel in the hands of the operator.

The remote control allows the operator to work at ambient temperatures from minus 60 ° C to plus 85 ° C.

The program method provides protection from the “rattle” of tumblers, which excludes the possibility of the operator taking erroneous actions. Also, the remote control has a mutual locking of the toggle switches, i.e. while holding the TURNER / DEPLOY switch 3, pressing the switch TILT the PMU 4 does not change the angle of the mast platform in the horizontal plane and vice versa, which completely eliminates the possibility of unauthorized control.

In the event of a sudden power failure, the mast is locked at its current height. In this case, the operator will be able to continue working with the mast manually.

The proposed remote control provides:

- improvement of operational characteristics due to the selection of optimal control algorithms;

- protection against unauthorized management;

- the exception of the so-called “human factor”;

- the implementation of diagnostics during all operations with a stop of the device;

- the ability to work with increased requirements for climatic and mechanical stresses;

- the ability to change the operation algorithm without hardware correction.

This technical solution allows you to not depend on the dips of the primary power supply voltage (especially when working offline).

In this remote control panel, “hot” switching on and off of the remote control is possible, i.e. the operator has the ability to quickly connect / disconnect the remote control without removing the power supply voltage of the complex, which is especially true during active hostilities.

The mount 5, located on the remote control housing, allows you to suspend the remote control on some hook to locate the remote control at the operator's level of vision.

The technical advantages given are those of a remote control panel implemented in accordance with FIG. 2, 3, 4 are confirmed by tests in one of the development projects.

Thus, due to the fact that the known device, consisting of the main composite elements, such as the housing, cable and pressure controls, additionally introduced display elements, niches in the upper part of the housing, a microcontroller, protection against unauthorized control and erroneous actions is provided remote control operator.
