Description

The invention relates to the field of signaling that responds to undesirable conditions and, in particular, to devices that detect and signal the presence of the necessary documents from the driver of the car at the time of starting the car engine.

Known devices that allow you to determine the presence of an object in the room, designed to detect keys, control panels, personal items. When using such devices, an alarm unit is attached to a preselected item and subsequently, when an audible (clap, whistle) signal is supplied, the unit gives a response signal (Key Detection Device - http://white-slon.ru/product/36315; http: / /vesh.com.ua/index.php?productlD=1029).

The disadvantage of such tools is the initiation required by a person for a search, which does not guarantee that a person can forget to take this item with him.

The closest solution to the claimed one is the solution presented on the website http://www.ids.by/ids/ru/ids.nsf/ParseFrameSet?OpenAgent&FS=F08D7B018F9008D CC2257426003840E1 & Doc = AC2500C4754989FAC225742B004FBFBB and describing a lady who forgot her bag. At the bottom of such a bag is an integrated RFID receiver that reads signals from RFID tags, which are equipped with the most necessary things (for example, keys or a mobile phone). If the hostess forgot to put any of these things in her purse, the corresponding indicator immediately lights up on the Ladybag surface.

When using such a rather complex device, constant monitoring and searching of things on which RFID tags are fixed, which requires increased energy consumption, is carried out. Also, this device requires turning on for its use, which does not guarantee from the ability to forget the necessary things, as well as from the ability to forget the entire bag with all things.

The objective of the claimed utility model is the creation of a device for signaling and monitoring the presence of an object providing a technical result, which consists in simplifying the device and the ability at the right time without human intervention to control the presence of the object in a limited space.

The essence of the utility model lies in the fact that the device for signaling and monitoring the presence of an object in a limited space includes an RFID tag, a reception unit and an indication unit, an RFID tag is located in a means for storing automobile documents, and a reception unit and an indication unit are located in the passenger compartment vehicle, the RFID tag has a radio channel for communication with the receiving unit, the output of which is connected to the input of the display unit, and the input of the receiving unit is connected to the standard connector of the contact group of the vehicle’s ignition lock.

The display unit can be made in the form of a speaker or as an LED installed in the passenger compartment in the driver’s field of view or in the form of a projector to project information onto the windshield of the car.

The mark can be made in the form of a plastic card for placement in the standard compartment of the means for storing documents. Also, the label can be mounted in the stiffener of the means for storing documents, such as a purse.

The inventive device is characterized by economical energy consumption, since it implements the frequency of sending an active tag signal in 15-20 seconds, which allows to increase the life of batteries up to 5-7 years. This frequency is comfortable for the user, since it usually takes a specified period of time to prepare for movement and ensures that the device responds before the vehicle starts to move. The device works without the need to turn it on by a person, this provides a guarantee against “forgetting” automobile documents located in any storage medium with a mark located in it before the vehicle starts to move. The device is activated every time before the vehicle starts to move, thus eliminating repeated “forgetting” after the first warning, even in the case of repeated “forgetfulness”. At the same time, the operation of the device provides only the supply of sound, light or combined information to a person, does not affect the control circuit of the car and does not interfere with the movement. Therefore, the final decision on the continued operation of the vehicle after receiving information about the forgotten documents is made by the person.

The following drawing illustrates a utility model:

Figure 1 Block diagram of a device for signaling and monitoring the presence of an object in a limited space (with connection to the standard connector of the contact group of the ignition switch of the car).

The device contains an RFID tag 1, a receiving unit 2, an indication unit 3. An RFID tag 1 has a radio channel for communication with a receiving unit 2, the output of which is connected to the input of an indicating unit 3, and the input of a receiving unit 2 (when using the device) is connected to a standard connector 4 contact groups of the ignition lock of the car.

Tag unit 1, for example, contains batteries, a controller, a transceiver, and an antenna. To implement the block can be used:

CR2016-CR2430 format batteries;

ATmega48PA controller, PIC16C56;

CC2500 transceiver, nRF24L01;

ceramic antenna 2450AT45A100, on a printed circuit board.

The receiving unit 2 contains an antenna, a transceiver, a controller, a voltage stabilizer. To implement the block can be used:

ceramic antenna 2450AT45A100, on a printed circuit board;

CC2500 transceiver, nRF24L01;

ATmega 128 controller, PIC16C56;

voltage stabilizer AS2431A1D, KA431ACZ.

The display unit 3 contains a speaker and / or LED. To implement the block can be used:

speaker 35KS08, 40KS08;

LED housing LA 41B / G, LA 32B / I.

When using the device, a standard connector 4 of the contact group of the ignition switch of a car of any type can be used (see Fig. 1) (depends on the model of the car).

The mark can be made in the form of a separate element, for example, a plastic card for placement in the standard compartment of a means for storing documents, or in the form of a keychain, etc. It can also be a structural element of a means for storing documents (mounted in a stiffener), for example, a purse, card holder, briefcase, etc.

The receiving and indicating units can be made in the form of separate or built-in modules, for concealed or outdoor installation in the passenger compartment.

The display process can be sound or light, as well as a combined type. With the sound version, the internal speaker of the device or external car speakers can be used. The light version of the indication is performed in the form of a light device (in the driver's field of vision) or in the form of a "projector" for projecting information onto the windshield of a car, which are installed in the passenger compartment.

The device operates as follows.

The driver turns the key in the ignition switch (presses the START button) of the car, while the control signal is received at the input of the receiving unit, the device turns on and searches for the RFID tag. In the absence of an RFID tag in the passenger compartment of the vehicle, the display unit provides a warning signal.

After receiving information in the form of a sound and / or light signal indicating that the driver has forgotten, for example, a purse with car documents, the person either stops trying to start the car and returns for forgotten documents or decides to continue driving without documents, realizing that he violates traffic rules (SDA).

Thus, the claimed device allows at the right time without human intervention to control the presence of an object in a limited space.
