Description

Security Detector Receiver STS-106

The technical field to which the utility model relates.

The utility model addresses the technical means of burglar alarms, and can be used in perimeter and territory security systems to control the location and movement of people.

State of the art

A known security linear detector (RF patent for utility model No. 90244, publ. 12/27/2009) containing a sensitive element mounted on a fence connected to an electronic unit containing an amplification unit, the outputs of which are connected to the inputs of the low-frequency and high-frequency channels, the outputs of which are connected with the corresponding inputs of the ADC, the outputs of which are connected to the corresponding inputs of the alarm generating unit, into which the mode switch, the means for adjusting the low-frequency and high-frequency channels, while the ADC and the alarm generation unit are made on a microcontroller with a built-in memory of signal parameters corresponding to various designs of barriers and methods of influencing them, while the control circuits of the microcontroller and means for adjusting the low-frequency and high-frequency channels are made with PIN code protection, and the means adjustments of the low-frequency channel, means for adjusting the high-frequency channel, the mode switch is connected to the RS 485 port through which the parameters of the signal are entered the catch stored in the memory of the microcontroller.

A disadvantage of the known detector is the relatively low sensitivity of the detector.

Known detector, including a power input, a detector connected to a data processing device connected to an output signal generating device in the form of a switch (electromechanical or optoelectronic relay), included in the break of the alarm loop of the control panel. In the known device, the detector power input is connected to an external network power source via a separate line (four-wire connection), and the alarm of the control panel is transmitted via an alarm loop equipped with an end resistor by opening the alarm loop using relay contacts

(VV Volkhonsky. Security alarm devices. - St. Petersburg: Ecopolis and Culture, 2001, p. 95, 104-106).

The known device has the following disadvantages:

- a four-wire switching circuit, which increases the cost of installation compared to a two-wire circuit, and also requires the installation of additional network power supplies;

- high current consumption, due to the need to constantly maintain the relay in the on state to give an alarm when the detector is disturbed or malfunctions, as a result - limited length and large cross section of the power wires, high power network power supplies;

- lack of diagnostics of the alarm loop disarmed, since there is no way to distinguish between an open loop of an alarm and a detector.

The last drawback, however, is eliminated by the fact that the relay contacts of a known device are shunted by a resistor.

A security detector is known, including a power input and an output device connected in parallel, containing a series-connected limiting resistor and a switch, the control input of which is connected to the alarm output of the data processing device (V.V. Volkhonsky. Alarm devices. - St. Petersburg: Ecopolis and Culture, 2001, p. 95, 104-106). In this case, the detector power input is connected in parallel to the alarm loop, and the detector is powered from the alarm loop (two-wire connection). In the well-known security detector, the alarm of the control panel is transmitted via an alarm loop of the "current loop" type equipped with an end resistor, by reducing the internal resistance of the detector when the switch closes.

A disadvantage of the known device is the ability to work only with those control panels that support a loop signal type "current loop". Such a loop requires a more complex device of the control panel and leads to an increase in the cost of its design. A disadvantage of the known device is that when it fails, an alarm signal is not generated.

The closest in technical essence and the achieved result is a security detector (RF patent for the invention No. 2292084, publ. 20.01.2007), and the detector detector contains a data processing device that is connected to the output signal generating device in the form of a switch. The security detector contains an electronic key as a switch.

A disadvantage of the known security detector is relatively low

The detector structural elements (see FIG. 6) are designated as follows: sleeve 12, nut 13, housing 14 with housing cover 15, base 16 with base cover 17, screw 18, cable 19.

The movable platform 10 is designed to mount the receiver of the security detector, and provides the ability to control the installation of the detector in height and / or angle towards the transmitter. The rod 9 with the help of fasteners 11 is attached to the supporting support on the guarded object.

The detector detector of the security STS-106 contains a receiving antenna 1, the output of which is connected to the input of the detector 2 connected to the amplifier 3, the first input of which is connected to the comparator 4, and the second input is connected to the key 6, connected to the control unit 5, the comparator 4 is further connected with the decision node 7, the control element 8 is connected l by the control node 5 and the decision node 7, and the receiver is mounted on a movable platform 10 of the rod 9, attached to the supporting support, the movable platform 10 has the ability to move and / or rotation and subsequently th fixing on the bar 9.

The device operates as follows.

The receiver of the burglar detector works in conjunction with the transmitter (PRD). The transmitter (PRD) and detector receiver are located at opposite ends of the protected area. The transmitter (Rx) emits electromagnetic waves in the direction of the detector. The receiver (PRM) of the detector is pre-fixed on a movable rod platform attached to the support support at the guarded object. This design provides the ability to control the installation of the detector in height and / or angle in the direction of the transmitter (Rx).

The receiver (PFP) of the detector receives electromagnetic waves, converts them

four

into an electrical signal and analyzes this signal.

A controllable transmitter generator (Rx) produces a pulse sequence of a certain duty cycle. Under the influence of pulses from a controlled transmitter oscillator (Rx), the transmitter modulator (Rx) generates a sequence of microwave radio pulses that are transmitted to the transmitting antenna of the transmitter (Rx). The transmitting antenna emits microwave radio pulses in the direction of the receiving antenna 1 of the receiver (PFP) of the detector. The electromagnetic field formed between the transmitting antenna of the transmitter (Rx) and the receiving antenna 1 is a source of useful signals for detecting objects crossing this electromagnetic field.

A person crossing the detection zone causes modulation of the signal at the receiver input (PFP) of the detector. An exemplary view of the shape of the detection zone is shown in FIG.

3. The depth of modulation and the waveform depend on the height and weight of the person, the intersection of the site, the topography of the site, and the speed of movement.

If a person moves close to the antennas (closer than 15 ... 20 m), then the signal is a single negative surge of a large modulation depth.

If a person moves further than 15 ... 20 m from the antennas, the signal is a series of successively alternating positive and negative emissions of small depth of modulation, while the time interval between adjacent positive and negative emissions and their duration depend on the speed of the person.

From the output of the receiving antenna 1, the microwave pulses arrive at the input of the detector 2 and then to the amplifier 3. The amplitude of the amplified pulses contains information about the state of the electromagnetic field and, accordingly, about the presence of foreign objects in it. From the first output of the amplifier 3, the signal goes to the input of the comparator 4, which determines the presence of pulses at the output of the amplifier 3 and informs the control unit 5 about it, which opens the key 6 and allows the passage of pulses to the decision unit 7. The decision unit 7 determines the state (closed / open) of the output optical relay. The control element 8 sets the synchronization method of the controlled transmitter generator (Rx) using the control unit 5, which in turn determines the moments of opening the key 6. In turn, the decision making unit 7 sends data about the current state (alarm, malfunction, norm) via the interface RS-485 in software.

Weather station (MS) for monitoring weather conditions (wind strength, precipitation, temperature) constantly transmits current weather conditions to the collection and processing system

Information (SSOI). The SSIR using an adaptive algorithm compares the current sensitivity to changes in the electromagnetic field between the transmitter (Rx) and the receiver (Rx) with a table of sensitivities relative to weather conditions, and in case of difference, changes it to the corresponding one. An adaptive weather sensitivity algorithm is shown in FIG. four.

In the near zone of detector A (see Fig. 5), the fact of crossing the guarded border is detected in Doppler radar mode, in the far zone, the fact of crossing the border is detected by detector B, which works only in receiver mode.

Thus, the claimed receiver of the security detector provides an increase in the sensitivity of the security detector, due to the possibility of adjusting the signal reception zone directly at the guarded object.

A comparative analysis of the claimed utility model showed that the set of essential features of the claimed device is not known from the prior art and therefore corresponds to the patentability condition “Novelty”.

The above information confirms the possibility of using the declared detector detector for receiving electromagnetic waves, converting them into an electrical signal, and can be used in perimeter and territory security systems to control the location and movement of people, and therefore meets the patentability condition “Industrial Applicability”.
