Examples

In the embodiment shown in the drawing, the device according to the invention comprises a control module 1 and a detection module 2. The control module 1 is mechanically connected to the object to be inspected 3, for example by a mobile phone, luggage or the like. be the control module 1 an integrated part of the object to be inspected 3, for example a mobile phone. If the object to be inspected is a person, it may be attached to it, for example, by means of a bracelet mounted on a body portion, a variety of fasteners to his clothing, and the like.

The control module 1 comprises a first receiver 11 and a first transmitter 12, an operator 10 connected to the alarm device 14 and optionally a separate power supply 19. Alternatively, the control module may be connected to the power supply of the controlled device 3, if so equipped. The operator 10 comprises a control and evaluation unit 13 (RVJ13). which comprises a control signal and alarm signal generator and decoders of the activation and test signals and the detection signal and optionally the control signal. The alarm device 14 is provided with audible or optical signaling. In the embodiment shown, the control module also includes a delay switch 18 connected to the module 1 and the object to be inspected by a mechanical coupling 17. In the event of undesirable delay, the delay switch 18 breaks the safety loop of the RVU 3, which then generates the appropriate alarm signal.

The detection module is intended for the user or the device controlling the position of the object to be inspected 3, or the distance between the control module 1 and the detection module 2. The user may attach it to a garment such as a so-called Velcro who usually carries it, like a watch chain.

The detection module 2 comprises a second receiver 21 and a second transmitter 22, an operator 20, which is connected to a second receiver and a second transmitter, and an alarm device 24 connected to an operator 26. The operator 26 consists of a control and evaluation unit 23 (RVJ23). The RVT23 unit comprises a control signal and alarm signal decoder and an activation signal and test signal generator or a control signal generator, respectively. The detection module 2 is powered by an independent power supply 29.

The function of the device is based on measuring the intensity of the control signal transmitted by the control module 1 and received and measured by the detection module 2, which intensity is dependent on the distance between the two modules 1 and 2 or other factors limiting the propagation of the signal such as various obstacles etc. modules 1 and 2. 9 9 9 9 9 • · · · · · · · · · · · · · · · · · · · ·

9999 999 99 9 communication between module 1 and module 2 is provided by the first receiver 11 and the first transmitter 12 of the control module 1 and the second receiver 21 and the second transmitter 22 of the detection module 2.

The control edge distance between module 1 and module 2 is determined by adjusting the nominal value of the signal strength emitted by the first transmitter of module 1 and received by the second receiver of module 2. The control signal is an analogue or digital signal with carrier wavelength allowed for industrial communications technology according to the equipment is used and for which it is equipped with the appropriate certificate and homologation. The control signal is modulated by a special code set for the device in the RVJ13 unit and generated by the appropriate control signal generator. The RVJ23 is then equipped with the appropriate decoder of this control signal.

To control the nominal value of the control signal intensity corresponding to the determined control distance between module 1 and module 2, the controller 25 of the detection module 2 operator 20 is used to set the control circuit in the RVJ23. Activation of the device is effected by switching on the activator 26 of the detection module 2, in which its control and evaluation unit 23 sends an activation signal via the second transmitter 22 and the first receiver 11 to the module operator 1 or the activation signal decoder of the RVJ13 unit. the signal that is transmitted by the first transmitter 11. The control signal is received by the second receiver 22 and decoded by the control signal decoder of the RVJ23. If the intensity of the received control signal measured in the evaluation unit 23 falls below the nominal value set by the controller 25, or even approaches zero due to the control distance between the control module I and the detection module 2 being exceeded or the control module being deactivated inadvertently, The alarm device may have a different output, for example a sound, optical, optionally in the form of a vibrator, and the like.

For the purpose of sound or optical detection of the position of the module 1 and the object 3 controlled by it, another activator function 2 can be used, which is triggered by sending a correspondingly coded detection signal from the second transmitter 22 of the module 2 to the first receiver 11 of the module 1. signal and triggers the corresponding alarm module 14 of the control module. This function can also be performed automatically, for example simultaneously with the activation of the alarm device 24 of the module 2.

Alternatively, the triggering of the alarm device of module 1 by the second alarm signal of module 2 can be made dependent on crossing the longer distance between modules i and 2, respectively further decreasing the intensity of the control signal, without having to manually activate the second alarm signal. Its level corresponding to this distance is set again by the controller ··

25. so that the alarm device of module 1 is automatically triggered when the control signal intensity decreases again, i.e. when the distance between modules 1 and 2 is further increased.

In order to test the coordination of the functions of the two modules i and 2, the detection module 2 is equipped with a tester 27, after which the user generates a test signal by the RVJ23 generator and transmits it via transmitter 22 to module 1 where it is decoded by the test signal decoder. the control detection signal and sends it via the first transmitter 12 to the detection module 2, whose RVJ23 activates the alarm device 24. Simultaneously, according to another embodiment of the device, the alarm device 14 of the control module 1 can be activated in a similar manner. , for example, by activating the button for a certain amount of time, such as more than two seconds.

In order to save the power source used to operate the control signal transmitter 12, the module 1 may be provided with a stand-by function which is first activated by pressing the activator button 20 and transmitting the respective activation signal. However, in this mode, the transmitter 12 does not transmit any signal. Only after pressing the activator button 20 again during a predetermined period of time will the activation of the transmitter 12 of the module RVJ13 be triggered by the next activation signal. Its operation can again be limited to a certain amount of time required for the user to determine whether the set control distance has been exceeded or not.

In the described embodiment, the power of the first control transmitter 12 and the second control signal transmitter 22 is preset to the same value, with the regulator 25 adjusting the nominal value of the intensity of the received control signal. Of course, there is another alternative in which the control distance is set by controlling the power of the transmitter of the control module 1 at a set nominal nominal value of the intensity of the received control signal. In this case, the power of the first transmitter 12 of the module 1 must be adjusted by the controller 25 by generating another coded signal in the control and evaluation unit 26 and transmitting it by the second transmitter 22 via the first receiver 11 to the RVJ13 unit. which decodes the signal and adjusts the respective power of the first transmitter 12, and thus adjusts the controlled distance. The greater the power of the transmitter 22, the greater the controlled distance will be set at a constant minimum intensity of the received signal.

The device can also be equipped with floating coding calibration, or switching to master and slave master / slave mode.

The invention is not limited to the embodiment described. It is obvious to a routine expert that the detection module can control more than one object, or the control circuits of the control and evaluation unit of the detection module can be multiplied so that different conditions can be set for individual objects ·· ····. For more complicated or comfortable operation, the unit can be equipped with a corresponding display, etc.
