Abstract
The utility model relates to an anti-theft alarm device, which effectively overcomes the false alarm of digital coding and the leakage alarm of wireless language and provides a multi-address, single cable, and language-positioning alarm device. The utility model is composed of a plurality of positioning units installed in a monitoring room, and an amplifier installed in a duty office, and the positioning units and the amplifier are connected by a cable. Each of the positioning units is composed of a sensing switch device (gate control, infrared, ultrasonic), a code switch device, an oscillator and an address language generator. When theft occurs, the sensing switch device works, and a language address is transmitted to the amplifier through the single cable to alarm. The utility model has the advantages of simple structure, convenient operation and installation and high cost performance, and can be used for anti-theft alarm.
Description
The utility model belongs to a kind of anti-theft alarming equipment.
What come out at present has polytype anti-theft alarming equipment (alarm, warning device, warning device), as break line type, microwave type, infrared type; Also have: (1) cabled digital coding is reported to the police, and (2) wireless sound is reported to the police.Though above-mentioned all kinds panalarm possesses some good points, also there is deficiency separately.Wherein, the cabled digital coding is reported to the police, since the existence of the bit error rate, unavoidable appearance wrong report; Wireless sound is reported to the police, because the barrier action of buildings, the dead angle of received signal often occurs and fails to report.
The purpose of this utility model is to overcome the wrong report of cabled digital coding and failing to report of wireless sound, and the burglar alarm of a kind of multiple access, single cable, language location is provided, and guarantees that warning function is accurate.
The purpose of this utility model is achieved in that to be that burglar alarm is made up of positioning unit, a sound amplifier and a power supply that is installed in the duty room that several are installed in each supervision room.Connect with a cable between positioning unit and the sound amplifier.
Each positioning unit is made up of sensitive switch device, cipher switch device, oscillator, address language generator.Sensitive switch device design has gate, various ways such as infrared, ultrasonic, select for use wherein one or more all can, it is many more to plant number, then function for monitoring is strong more; It is serially connected between address language generator and the sound amplifier with parallel form.When the robber enters certain room, as long as any sensitive switch device is in on-state, then sound amplifier reports that promptly the signal of feelings takes place to steal in this room.The cipher switch device is room owner design, and owner enters before the room behind the pressing password, has promptly cut off the path of address language generator to sound amplifier, avoids reporting by mistake because of the room owner enters.
Oscillator is a kind of oscillatory circuit commonly used of constantly exporting trigger pulse by required interval time.
The address language generator is a language integrated circuit, and by microphone, language is simulated signal import in this circuit and store, under oscillator triggers, OPADD speech signal synchronously.
Owing to adopt such scheme, can monitor simultaneously in duty room that numerous room and identification like clockwork steals feelings and use language alarm, can not occur reporting by mistake and failing to report.Apparatus structure is simple, and is easy to install, ratio of performance to price height.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the device block diagram, and Fig. 2 is the positioning unit schematic diagram, and Fig. 3 is oscillator and address language generator circuit figure.1-positioning unit wherein, 2-sound amplifier, the single cable of 3-, 4-power supply, 5-sensitive switch device, 6-cipher switch device, 7-gate controlled switch device, 8-infrared switch device, 9-ultrasonic switch device, 10-oscillator, 11-address language generator.The G-transistor, D-crystal diode, R-resistance, C-electric capacity, K-switch and sensor, M-cipher switch, J-relay, IC-integrated circuit, the A-oscillator output end, the playback of B-address language generator triggers input end, B '-address language output terminal, H-microphone.
As shown in Figure 1, this device is each positioning unit (1-1), (1-2), (1-3) that is placed in each room (i.e. the place that need monitor) by several ... (1-n) and be placed in the sound amplifier (2) of duty room, single cable (3) and power supply (4) four parts composition.Each positioning unit plays identification and steals feelings, and single cable plays transmission signals, and sound amplifier plays the warning effect, and power supply is the DC voltage-stabilizing power supply.For being connected in parallel, connect with single cable between positioning unit (room) and the sound amplifier (duty room) between each positioning unit.When arbitrary room (as rooms 323) occur stealing feelings, the positioning unit work in this room, the output language address signal, that is: " there are robber's feelings in rooms 323! ", transmit by single cable and to make the sound amplifier of duty room send that " there are robber's feelings in rooms 323! " sound, the operator on duty just can take corresponding measure to arrest the robber after hearing warning.
By Fig. 2, Fig. 3 as can be known, each positioning unit is made up of sensitive switch device (5), cipher switch device (6), oscillator (10), address language generator (11).Sensitive switch device, design have gate controlled switch device (7), red place derailing switch (8), ultrasonic switch device (9), for being connected in parallel.Each derailing switch all has the single-stage transistor amplifier, and its base input end inserts gate controlled switch (K respectively
7), infrared sensor (K
8), sonac (K
9), collector is succeeded electrical equipment winding (j respectively
7), (j
8), (j
9).Each relay contact (j
70), (j
80), (j
90) be normally open, be serially connected in after the parallel connection in single cable.When the robber opens door, gate controlled switch device (7) is because of gate controlled switch (K
7) disconnect relay winding (j
7) energising, contact (j
70) connect.After the robber enters the room, as a same reason, because infrared sensor (K
8), sonac (K
9) work, make contact (J
80), (J
90) also connect.Here three kinds of derailing switches enumerating all have the effect that feelings are stolen in identification, uses any, two kinds or all can, the kind number is many more, the function of supervision is strong more.
Oscillator (10) is an oscillatory circuit commonly used, produces the pulse triggering signal of certain intervals time incessantly, adjusts resistance R
101Can change its duration of oscillation at interval.Address language generator (11) is a language integrated circuit, inserts microphone (D) at the MIC place, and by microphone, making language simulate signal (" has robber's feelings as rooms 323! Store in ") typing language integrated circuit.Be connected because oscillator output end (A) triggers input end (B) with the playback of address language generator, under the trigger pulse effect, there are robber's feelings in address language the signal (" rooms 323 of address language generator! ") is from output terminal (B ') output synchronously.When not taking place to steal feelings, because the contact (J of sensitive switch device
70), (J
80), (J
90) be normally open, promptly single cable interrupts, so address language can't be transferred to sound amplifier, does not have alerting signal.Only when stealing feelings, because the contacting of sensor, address language promptly is transferred to sound amplifier, sends alerting signal.
Cipher switch device (6) has the single-stage transistor amplifier equally, its base input end access pin switch (M
6), collector connecting relay winding (j
6), relay contact (j
60) be normally off, the room owner advances before the room behind the pressing password, relay winding (j
6) energising, relay contact (j
60) disconnect, promptly cut off the interface channel of address language generator and sound amplifier.
