Abstract
The utility model relates to a truck goods losing alarm circuit, which comprises a relay(J), a sound circuit(Y), a switch(K), two indicator lamps(LD and HD) and a signal line(L), one wire of the relay(J) is connected with a power cord wiring column of the vehicle ignition switch(K), the other signal line(L) passes through goods(H) to form a relay winding loop, a positive electrode is connected with a power supply, a negative electrode is earthed, and the two indicator lamps(LD and HD) are connected with the relay(J) and the sound circuit(Y) respectively; when the alarm circuit is electrified, a normally closed relay contact is disconnected, the sound circuit is disconnected, so that no alarm is sent out; and when goods fall down, the signal line is broken, the relay winding loop is disconnected, the relay contact is closed to switch on the sound circuit, and the alarm is sent out. The alarm circuit has the advantages of simple structure, convenient and reliable use, easy operation and low cost.
Description
Technical field
The utility model relates to a kind of warning circuit, and particularly the truck goods is lost warning circuit.
Background technology
Full-sized car in the process of moving, goods falls down to lose and happens occasionally.Trace it to its cause is that the driver is difficult for finding to the thing that takes place behind the car in pilothouse, for reducing the loss, driver's observations of in driving way, will constantly stopping, quite trouble is also failed thoroughly to solve goods and is lost the loss accident generation, for solving the generation of above-mentioned incident, the be everlasting different azimuth of vehicle body of driver installs visor additional, observing goods, but because vehicle body is longer, goods is different, poor effect; The high-tech means such as employing wireless launcher that also have have increased cost like this, and technical being difficult to accepted.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of truck goods to lose warning circuit, and is simple in structure, easy to use and reliable, with low cost.
The utility model is achieved through the following technical solutions: a kind of truck goods is lost warning circuit, it comprises relay J, acoustics circuit Y, K switch, two pilot lamp LD, HD and a signal wire L, the power lead that a lead of relay J is connected on automobile ignition switch K connects on the post, another root signal wire L constitutes the relay winding loop after passing goods H, positive pole connects power supply, negative pole is taken ground, and two pilot lamp LD, HD are connected to relay J and acoustics circuit Y respectively; The normally closed relay contact disconnects after energising, and acoustics circuit is obstructed, and alarm free when goods falls, is broken signal wire L, and the relay winding loop is cut off, and relay contact closure is connected acoustics circuit, produces to report to the police.
The beneficial effects of the utility model: simple in structure, easy to use and reliable, easy to operate, cost is low.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, a kind of truck goods is lost warning circuit, and it comprises a relay, an acoustics circuit, a switch, two pilot lamp LD, HD and a signal wire, indoor in car steering, with the 12v power supply on the automobile, the power lead that lead of relay is connected on automobile ignition switch connects on the post, and another root signal wire constitutes the relay winding loop after passing object, positive pole connects power supply, negative pole is taken ground, and normally closed relay contact, energising back disconnects, and acoustics circuit is obstructed, alarm free, when goods falls, break this line, the relay winding loop is cut off, relay contact closure, connect acoustics circuit, produce and report to the police, pilot lamp HD and acoustics circuit are parallel/serial, two pilot lamp LD, HD, when green light LD was bright, the junk warning when taking place in expression alarm operate as normal, red light HD is simultaneously bright, and two kinds of warning effects of acousto-optic are arranged.
