Abstract
The invention relates to an anti-theft induction device aiming at an open type truck, which comprises one or more infrared distance measurement unit(s) that is/are positioned at the rear of or at the side of the truck and used for detecting the distance of surrounding objects, and an alarm unit connected with the infrared distance measurement unit(s); and the alarm unit gives an alarm for prompting when an unidentified object enters the alarm distance of the truck. The device can be used monitoring the rear and the side of the truck, and the driver can be prompted by the alarm unit to take action when the unidentified object attempts to come near or cling to the rear or the side of the truck, so that the goods in the truck can be avoided being stolen when in the driving process.
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:
The invention provides a kind of device that can solve the antitheft 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: anti-joyride device includes: be positioned at one or more infrared distance measurement unit of lorry rear or side, be used to survey the distance of object on every side; With the alarm unit that the infrared distance measurement unit links to each other, described alarm unit, when unknown object enters the lorry alarm distance, send alarm; There is the threshold setting knob infrared distance measurement unit, can adjust as required and set the warning distance of reporting to the police; System also comprises the power supply that links to each other with alarm unit with the infrared distance measurement unit.
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 an infrared distance measurement cell position scheme of installation of the present invention.
Fig. 2 is a device block diagram 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, infrared distance measurement cell position scheme of installation of the present invention.Mainly infrared distance measurement 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, infrared distance measurement unit 11-14 links to each other with power supply 20.The infrared distance measurement unit, the time difference of returning by detection of reflected is determined the distance of object.The remote reflective infrared switch of industrial practicality can directly be chosen in the infrared distance measurement unit, also can make range cells according to actual conditions, because the technology of infrared distance measurement is very ripe, belong to those skilled in the art technique known, no longer do too much explanation at this.
In the infrared distance measurement unit, be provided with the knob that to regulate threshold value, the threshold distance that can report to the police by the adjusting knob adjustment according to actual needs.The power supply of infrared distance measurement unit can be chosen the battery power of lorry with 24V or 12V direct supply, also can use battery that range cells is powered.Warning device adopts light-emitting diode and buzzer phone to form.
In actual applications, at the tailstock or side the infrared distance measurement unit is installed, in object enters fence coverage, is then touched 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 infrared distance measurement.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.
