Description

Encapsulated electronic assembly

Technical Field

The utility model relates to a machine-building field supplies to use in applicable rope segment is for preventing unauthorized entering and guaranteeing all trades of control of protected facility integrality as shutting unit to, it is applicable in executing and sealing transport means, carriage, container, garage, warehouse, etc..

Background

Clamping mechanisms for clamping lengths of rope are known in the state of the art, described in patent document [1], in which the rope is made with the ability to pass it through the ear of a locked facility. The first end of the string section is rigidly inserted into the housing, while the second end is clamped in a clamping unit in a clamping mechanism built into the housing. The known device is equipped with electronic means placed on the casing and made for the ability to transmit signals relating to the integrity of the rope. The rope is made of steel and is provided with current conductors constituting a circuit, which are placed therein and connected to the strands of the rope. The terminals of the external strands are connected, through associated contacts, to an electronic device constituted by a memory unit, a power supply and a transceiver system made for the ability to output information on the availability of the equipment to a remote control station. This known device provides remote control of the integrity of the rope portion, but has a constructive drawback that prevents this effect from being guaranteed. These drawbacks are due above all to the fact that the facilities described in the known plants provide the ability to monitor the integrity of the steel ropes not completely, nor in all cases. The reason for this is that the conductor insulation placed inside the rope and outside the casing can be damaged during its use, which can lead to a parasitic electrical connection of the conductor to the strands. And if in this case cutting of the rope occurs, i.e. a malicious, unauthorized act, the electronic device will not record this because the conductor will be present together with the rope.

There is also known a sealed electronic component described by patent document [2 ]. Which includes a housing and a cord made for having the ability to pass it through the ear of the protected installation. The first end of the string section is rigidly embedded in the housing and the second end of the loop formed through the ear of the protected structure is rigidly secured in a clamping mechanism built into the housing. The rope damage sensor is a low frequency toroidal core transformer placed in a housing and surrounding the rope. The primary winding of the transformer is wound on a toroidal core and connected to a device for generating a test signal, i.e. a self-contained alternator. And the rope penetrating through the annular iron core is used as a secondary coil of the transformer. There is also provided a device connected to the rope breakage sensor and emitting a signal about the breakage of the rope upon receiving the related signal sent by said sensor.

A disadvantage of this sealed electronic assembly is that the oscillation frequency of the self-contained alternator depends on the thermal stability of the elements for which VT1, C1, R1 are applied. This leads to either a narrow working range or, in the case of high-quality heat-resistant components, to an increase in structure.

The known device does not support the discovery of rope bridging and subsequent rope breakage, i.e. that a wrongdoer would connect the rope being monitored to each other at two points by, for example, the use of large pliers, and, in addition, cut it off in the middle of the contact point, in which case the electronic device would not find the rope breakage.

Self-contained alternators fitted with VT1, C1, R1, T elements incur costs for the purchase and installation of these elements, deteriorating the weight and size parameters.

The closest analog to the device in the patent application is the encapsulated electronic assembly described by patent document [3 ]. The device comprises a housing, a rope, an annular core as a rope damage sensor on which a coil is wound and which surrounds the rope, a device for generating a test signal, the output of which is connected to the input of the rope damage sensor in the form of a first end of said coil, and the output of the rope damage sensor in the form of a second end of said coil is connected to an electronic device for monitoring closure and receiving, processing, storing and recording by means of electromagnetic signals for its reception by an external receiving device, and the rope passing through the annular core is made with the ability to form a short circuit with the housing.

The drawback of the closest technical solution is that it makes it possible to repeat the rope by using parallel conductors, subsequent rope breakage, position variation of the assembly in space. In this case, the electronic device will not find a rope break.

Detailed Description

As shown in fig. 1 and 2, the sealing electronics assembly comprises a metal housing 1 for locking the sealing device, a rope 2 made for its ability to pass through the ear of a protected installation (not shown), a device for generating a test signal realized in the form of a rectangular pulse generator 5 as a toroidal core (not shown) on which a rope damage sensor 3 is wound around a coil 4 (see fig. 2) and surrounding the rope 2, the output of which is connected to the input of the rope 2 damage sensor 3. To the output of said rope damage sensor 3 is connected an analog-to-digital converter 6, the output of which is connected to the input of an information processing, storage and transmission device 7, which is equipped at its input with a comparison device and a storage device (not shown) for storing a standard value of the output signal. In addition, a current limiting resistor 8 for the output of the generator to prevent a fault due to overcurrent is connected to the output of the rope damage sensor 3.

The square pulse generator 5, the analog-digital converter 6 and the information processing, storage and transmission means 7 are in this case housed in a complementary casing (not shown) made for the conditions of reusability.

In order to achieve a new function, namely monitoring the environmental magnetic properties and forming an alarm signal in case of a change of said magnetic properties, in a first embodiment of the assembly it is equipped with an inductor 9 made with the ability to be placed around said rope 2 and, in this example, with terminals connected to said inductor 9 and made with a second electronic device 10 made with the ability to receive, monitor, contrast the change of inductance of said inductor caused by the effect of a change of the environmental magnetic properties by using calibration thresholds set when installing the sealed electronic assembly for processing, storing and recording by using electromagnetic signals to transmit information for it by an external receiving device.

In another embodiment, the second electronic device may not be provided. The electronic device 7 for monitoring the closing and receiving, processing, storing and recording by means of electromagnetic signals information for its reception by an external receiving device may be provided with a second input terminal connected to said inductance coil 9 and made with the ability to monitor and contrast the inductance variation of said inductance coil caused by the effect of the environmental magnetic properties variation by means of a calibration threshold set when the sealed electronic component is mounted.

The inductor coil 9 is placed in close proximity to the sensor 3 and other magnetic material surrounding the rope 2, such as the sealed ear, lock or bullet lock sealing device of the protected installation.

In order to achieve the new function of monitoring the magnetic properties of the environment and of forming an alarm signal in the event of a change in said magnetic properties, in a further embodiment of the assembly, it is provided with a permanent magnet 11 and a magnetic field sensor 12 for concealed placement in the protected installation and preferably in the sealed ear of the protected installation, and the electronic device 7 for monitoring closure and reception, processing, storage and recording thereof by means of electromagnetic signals from an external receiving device is provided with a second input 13 connected to said magnetic field sensor 12 and made with the ability to monitor the reading of said sensor 12.

The square pulse generator 5, the analog-to-digital converter 6, the information processing, storage and transmission means 7 and the second electronic means 10 can be implemented on the basis of one or two microcontrollers, which is the optimal solution that makes it possible to obtain the best weight-size specification.

The encapsulated electronic assembly of the patent application operates as follows.

The short circuit occurs by passing the string 2 through the ear (shown limited in fig. 3) of the lock 14 of the protected installation (not shown) and the sensor 3, so that the terminals of the string 2 are fixed in a certain detachable or inseparable manner in the metal casing 1 of the closure-applying device.

The square-wave signal is transmitted directly to the sensor 3 input by the square-pulse generator 5.

The signal output by the sensor 3 is read by using an analog-to-digital converter 6. In the closed circuit condition of the rope 2, the signal sent from the output of the sensor 3 approaches a saw-tooth form, the form of which and its rate of distortion to a square wave signal depend directly on the characteristics of the inductor coil 4.

In the case of an opened string 2 circuit, i.e. if or if the sealing electronics has not been installed, or if the integrity of the string 2 is destroyed, then the signal sent from the output of the sensor 3 will be very different from the signal sent from the output of the sensor 3 in the presence of a short circuit of the string 2.

The signal sent from the output of the sensor 3 is digitized by an analog-to-digital converter 6 and the information about the current signal is transmitted to an information processing, storage and transmission device 7.

The information processing, storage and transmission means 7 process the data received from the analog-to-digital converter 6, analyze them, compare them with the previously received information and make a decision as to whether the integrity of the rope 2 has been compromised. The information processing, storage and transmission device 7 is equipped with an electromagnetic signal transmitter (not shown) for transmitting an output signal as to whether the integrity of the rope 2 has been compromised to a mobile or stationary external receiving device.

In turn to the described procedure for monitoring the integrity of the rope 2, to receive and process the monitoring of the environmental magnetic properties of the output signal of the inductive coil 9 (in the first embodiment of the assembly in the patent application) or of the sensor 12 (in the second embodiment of the assembly in the patent application).

The output signal of the inductor coil 9 or the sensor 12 will be set to a certain level when the assembly of the patent application is installed, depending on the material through which the inductor coil is made into a rope and the proximity of other magnetic materials, i.e. a lock or a bullet lock sealing device.

When the rope material is changed, or when the assembly is moved away from the protected installation, there will be a change in either the inductance of the inductor 9 or the magnetic field strength of the permanent magnet 11 and the signal transmitted by the sensor 12, which will be registered by the 7, 10 device which forms and transmits the alarm signal.

Alternately applying the method of monitoring strand integrity and the complementary monitoring of inductance by the inductor coil would eliminate the possibility of bypassing the monitoring circuit by closing and subsequently opening the strand circuit by application of the conductor and removing the main strand from the way.

Also, the ability to monitor changes in the magnetic properties of the environment provides the ability to determine positional changes in the sealed electronic components, i.e., ion lock movement, or the ability to determine the presence or absence of a metal housing within the confines of the seal housing that latches the sealing device.
