Abstract
The invention relates to an anti-theft induction device used for an open truck, comprising one or more ultrasonic distance measurement units on the back surface or side surface of the truck used for detecting the distance of peripheral articles, a host machine connected with the ultrasonic distance measurement units and used for processing the electronic signals transmitted by the ultrasonic units, calculating the distance between the article and the truck and judging whether the distance is a needed alarm distance, and an alarm unit which is connected with the host machine and emits the alarm prompts when the unknown article enters the alarm distance of the truck. The device can control the rear side and side surface of the truck; the alarm unit prompts the driver to take measures when the unknown article tries to approach to or be close to the rear part or the side surface of the truck, thus avoiding the goods in the running truck from being stolen.
Description
Technical field:
The present invention relates to a kind of antitheft induction installation at open lorry.
Background technology:
Traditional open lorry often has the stolen thing of goods to take place in transit.Particularly in the process of long-distance transport at night, the thief generally can be under the careless situation of chaufeur, from the automobile of tightly trailing from the rear of lorry or the side climb to lorry and get on, implement theft.In order to prevent the generation of this type of larceny, general way is to reinforce and add a cover protection cloth.But protection cloth but is easy to stolen one's share of expenses for a joint undertaking and scratches with cutter, can not play good anti-theft effect.Therefore, when goods vehicle driver was driven over a long distance at night, energy can not complete set on forwardly the road conditions, the situation that often will from back mirror, watch the rear.The attention of chaufeur can not be concentrated, and has increased the weight of driving fatigue, has more seriously caused the potential safety hazard in the driving process.
Summary of the invention:
Antitheft induction installation of the present invention can solve the anti-theft alarm problem of open lorry.Can deploy to ensure effective monitoring and control of illegal activities to lorry rear and side, as unknown object attempt near or during near the rear portion of lorry or side, alarm unit will point out chaufeur to take measures, so just avoided lorry goods stolen under steam.
In order to implement above-mentioned purpose, the present invention adopts following technical scheme:
Ultrasonic truck anti-theft device includes: be positioned at one or more ultrasonic ranging unit of lorry rear or side, be used to survey the distance of object on every side; With the main frame that the ultrasonic ranging unit links to each other, be used to handle the electronic signal that ultrasound unit transmits, calculate the distance of object and lorry, and judge whether to be the needs alarm distance; Alarm unit, described alarm unit links to each other with main frame, when unknown object enters the lorry alarm distance, sends alarm.
Alarm unit is made up of light-emitting diode and buzzer phone, can be installed in the operator's compartment, as unknown object attempt near or during near the rear portion of lorry or side, alarm unit will point out chaufeur to take measures; Alarm unit also can be placed in the rear portion or the side of lorry, as unknown object attempt near or during near lorry, directly give a warning for the vehicle of closely trailing, play theft-proof effect.
Because this device can play fine monitoring effect to all the not clear vehicle or individuals that attempt near lorry, can allow chaufeur understand the situation at lorry rear in time, so the present invention can solve the antitheft problem of open lorry.
Description of drawings:
Fig. 1 is a ultrasonic ranging cell position scheme of installation of the present invention.
Fig. 2 is a device block diagram of the present invention.
Fig. 3 is a device circuit principle schematic of the present invention.
The specific embodiment:
Below in conjunction with drawings and Examples, the present invention is described in further detail:
At first consult shown in Figure 1, ultrasonic ranging cell position scheme of installation of the present invention.Mainly ultrasonic ranging unit 11-14 is installed in the tailstock or the side of lorry, in the present embodiment, install one at the tailstock altogether, the both sides of car are installed three, amount to four range cells 11-14. and carry out the emphasis monitoring for four positions of a, b, c, d of lorry respectively.Certainly, also can only a range cells be installed, be used for monitoring at sensitive part.Lorry in the process of moving, if there have not clear vehicle to attempt from the back or the side of lorry to be stealthily close, when enter warning apart from the time, just warning device is excited, driver allows chaufeur take measures.Certainly, warning device also can be arranged on the side or the afterbody of lorry, directly gives a warning for the vehicle of closely trailing, and plays theft-proof effect.
Fig. 2 is a device block diagram of the present invention.Wherein, ultrasonic ranging unit 11-14 links to each other with main frame 20, and the power supply of ultrasonic ranging unit has main frame to provide, and also can power separately.Main frame sends the ultrasonic pulse signal of certain frequency, and the time difference of returning by detection of reflected is determined the distance of object.The signal that reflects back into the ultrasonic ranging unit is sent to that main frame amplifies again, detection, relatively wait processing.If detected distance is less than the warning value of setting, then main frame can send a warning by alarm unit.
Fig. 3 is a device circuit principle schematic of the present invention, wherein includes:
A plurality of ultrasonic rangings unit 11-14, its input end is connected to electronic switch 22 respectively;
Many group emission driving circuit 15-18, its mouth is connected with cooresponding ultrasonic ranging unit 11-14, and input end is connected with the treater of main frame by electronic switch 21,22;
Adjust the adjustment circuit 331-334 of sensitivity;
Power circuit 60.
The mode of operation of apparatus of the present invention is as described below in detail: mainly triggered in regular turn by electronic switch 22 by microprocessor and respectively organize driving circuit 15-18, making cooresponding ultrasonic ranging unit is that ultrasonic probe 11-14 launches in regular turn and receives super sonic, scan in regular turn by electronic switch 21 simultaneously and respectively organize the emission super sonic that ultrasonic probe 11-14 receives, and by institute's receiving element 30, produce a control signal through overdamping, amplification, sensivity control, detection and after relatively waiting a succession of signal conditioning step, and deliver to the microprocessor preservation of main frame.
After microprocessor is finished keeping in of four groups of reflected signals in regular turn, relatively four groups of signals are selected one group of nearest signal, and itself and inner setting value are compared, to determine whether object has entered in the fence coverage, in this way, then touch warning circuit 40 and produce sound and light alarm, the prompting chaufeur has object approaching, reminds chaufeur to take measures.
By above-mentioned explanation as can be seen, device of the present invention can play good strick precaution effect for attempting suspect vehicle stealthily approaching in the lorry traveling process by the method for ultrasonic ranging.Particularly in the process of long-distance transport, owing to work long hours during decreased attention, this device can play well auxiliary effect of taking precautions against when chaufeur.Because this device is simple in structure, easy for installation, low cost of manufacture has very high using value.
