Description

The inventive utility model relates to the field of instrumentation and can be used when conducting surveys of electromechanical devices, for example, elevator equipment.

A device [1] is known for assessing the operational life of a mechanical running system, comprising a counter sensor, an AND logic element, a rectangular pulse shaper, a clock control trigger and an indicator, where the counter sensor is mounted on the driving wheel of the running system and is a watch with an indicator. With a constant rotation of the drive wheel of the moving structure to which the sensor is connected, a time count occurs, and when stopped, the counter starts the delay countdown. When the set value is reached, the counter resets the trigger for controlling the operation of the watch and the time does not count down, which makes it possible to estimate the running time of the running system.

However, the known device does not allow simultaneous recording of the operating time and the number of starts of the controlled electromechanical device, as well as determining the resource consumption of mechanical systems, supporting structures (beams, frames), switching devices (relays, contactors, starters) included in the controlled device , the wear of which depends on the number of inclusions (loads),

The proposed utility model of the meter simultaneously determines the actual total operating time of the electromechanical device and the number of its switching on for the entire period of connecting the electronic meter to it, which allows us to solve the problem of determining the actual resource consumption of all systems, components, parts and structures of the monitored device. The newly introduced set of parameters taken into account is not found in the well-known patent and scientific and technical literature, therefore, the utility model meets the criterion of "novelty."

To solve this problem, an electronic counter is proposed containing a pulse forming unit, a power supply unit, characterized in that a pulse counter, a pulse duration meter and an adder are inserted into it, the output of which is connected to an indicator, the second input of which is connected to the output of the pulse counter, and the adder input connected to the output of the pulse duration meter, the input of which together with the input of the pulse counter is connected to the output of the pulse forming unit, the input of which is the input of the electronic counter ika.

The technical result is a constructive solution of the proposed counter, which allows you to simultaneously determine two parameters (duration, number of starts) needed to take into account the resource consumption of the controlled device at the moment of "life", as well as the ability to control a variety of electromechanical devices with different input signals that differ in amplitude and duration.

The technical result is achieved by the presence in the counter of the pulse forming unit and additionally introduced into the counter of the pulse duration meter, the adder and the pulse counter, interconnected and working in parallel.

The block diagram of the meter is shown in the figure, where are indicated:

1 - block pulse formation,

2 - meter pulse duration,

3 - adder

4 - indicator,

5 - power supply,

6 - pulse counter.

The electronic meter is structurally a device with dimensions of 80 × 57 × 35 mm, in which blocks 1, 2, 3, 4, 5, 6 are arranged. At the same time, indicator 4 has two scales, on one of which the number of starts is recorded, and on the other - total operating time of the monitored device. The counter also provides for the possibility of working from an autonomous power supply in the form of two batteries of 1.5 V each.

In this case, the input of the pulse forming unit 1 is a common counter input. The output of the pulse forming unit 1 is connected to the input of the pulse counter 6 and the input of the pulse width meter 2. The output of the pulse duration meter 2 is connected to the input of the adder 3, the output of which is connected to the second input of the indicator 4. The output of the pulse counter 6 is connected to the input of the indicator 4. Power supply 5 is connected to all functional elements of the counter (not shown in the figure). The counter works as follows.

The input voltage from the motion relay of the controlled device is supplied to the input of the pulse forming unit 1, which converts the input voltage to direct current, restricts the voltage level to the value necessary for the counter to work, eliminates harmonic components and suppresses “chattering” of the input signal.

Thus, at the output of the pulse forming unit 1, pulses are formed, the number of which is equal to the number of inclusions of the controlled device, and their duration is the duration of each inclusion.

From the output of the pulse forming unit 1, the pulses are fed to the inputs of the pulse duration meter 2 and pulse counter 6. The pulse duration meter 2 measures the duration of the pulses and generates a digital signal containing information about their duration.

From the output of the duration meter 2, the signal is fed to the input of the adder 3, in which the pulse duration is added. From the output of the adder 3, the signal goes to the indicator 4, which displays information about the total duration of the pulses.

The pulse counter 6 calculates the number of pulses arriving at its input from the output of the pulse forming unit 1. From the output of the pulse counter 6, the signal goes to indicator 4, which displays information about the number of pulses.

Thus, the counter indicator simultaneously displays the number of starts of the monitored device and the total duration of its operation for the monitored period, which makes it possible to estimate the resource consumption of the electromechanical device.

The meter can be installed in the cabinet of a low-voltage complete device (control system), for example, elevators, on any of the free panels, does not require special fastening and can work in any position.
