Abstract
The utility model discloses a kind of detectors that oily phenomenon is stolen based on piezoelectric transducer detection truck, and composition includes: active hydraulic cylinder, Slave cylinder, sensor, preamplifier, single-chip microcontroller, display instrument, alarm;By that must monitor to oil pressure in fuel tank, calculating of the single-chip microcontroller to fuel tank intermediate fuel oil depletion rate compares to monitor in real time and oily phenomenon steathily whether occurs with the numerical value set, reminds driver by warning device.
Description
Technical field
The utility model relates to a kind of sensors to detect instruction device, can especially identify whether the fuel tank of truck occurs
Oily situation steathily.
Background technique
Currently, the long-distance lorry for transporting cargo is more and more, at the same time, big in high speed due to the development of logistic industry
Lorry steals oily phenomenon and also grows in intensity, and especially in the case where night visibility is very low, becomes very stubborn problem,
Numerous drivers are allowed to feel very headache.It is some it is common prevent measures oily steathily include oil cap is changed into Thfet-proof cover of fuel tank or
Person using in reservoir port screening, above fuel tank plus by the way of baffle, but these modes are as taken totally ineffective measures, and it is basic not can solve
Problem.
Summary of the invention
The purpose of this utility model is to judge oily phenomenon steathily whether occur in time, by consuming in real time to truck fuel tank
Oil mass is detected, and notifies driver, to avoid property loss.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
The composition of the utility model include: active hydraulic cylinder, Slave cylinder, sensor, preamplifier, single-chip microcontroller,
Display instrument, alarm, the active hydraulic cylinder and Slave cylinder are closely coupled, and the sensor arrangement is from hydrodynamic pressure
The side end face of cylinder, and the overhanging piston of Slave cylinder passes through sensor and is pressed in the end face of sensor, the sensor with
Preamplifier is connected, and the amplifier is connected on the input terminal of single-chip microcontroller, and the output of the single-chip microcontroller is terminated with aobvious
Show that instrument and alarm, single-chip microcontroller are powered by automobile storage battery.
The utility model has the beneficial effects that depletion rate oily in truck oil tank can be monitored in real time, it is oily when occurring stealing
Situation can remind driver in time, and the energy for supporting this system to work can be ignored not compared with other electrical appliances in lorry
Meter, structure are simple.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing.
Fig. 1 is the mechanical device sectional view of the utility model.
Fig. 2 is the circuit module figure of detector.
Appended drawing reference: 1. active hydraulic cylinders, 2. Slave cylinders, 3. piezoelectric transducers, 4. preamplifiers, 5. monolithics
Machine, 6. display instruments, 7. alarms, 8. active rooms, 9. active hydraulic cylinder pistons, 10. slave operation rooms, 11. from hydrodynamic pressure
The cylinder piston.
Fig. 3 is the connection figure of the utility model mechanical device and circuit module.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model:
Active hydraulic cylinder is connected with Slave cylinder, is hydraulic oil in slave operation room, fixes in slave cylinder right end face
Have piezoelectric transducer, overhanging piston is passed through and is pressed on a sensor, and piezoelectric transducer is connected with preamplifier, amplifier with
Single-chip microcomputer input connection, output end then alarm and display.
As shown in Fig. 1 a kind of mechanical device for the detector that oil is stolen based on piezoelectric transducer detection truck, actively
Hydraulic cylinder (1) is connected to truck tank bottoms, enters the fuel oil in fuel tank in active room (8), by fuel tank
The pressure of intermediate fuel oil pushes active hydraulic cylinder piston (9) mobile towards Slave cylinder direction, when fuel tank intermediate fuel oil is to fill it up with shape
When state, Slave cylinder piston (11) is in the right side terminal point of slave cylinder, and the overhanging piston of Slave cylinder at this time is just
It touches piezoelectric transducer (3) and no pressure acts on;When the fuel in fuel tank is gradually consumed, active hydraulic cylinder piston
(9) reduced by the pressure from fuel tank, start the direction movement away from Slave cylinder, at this point, slave operation room
(10) pressure also accordingly reduces, and Slave cylinder piston (11) is mobile towards active hydraulic cylinder direction, and overhanging piston effect exists
Pressure on piezoelectric transducer is gradually increased, the output voltage of piezoelectric transducer also corresponding change.
In circuit module figure shown in Fig. 2, piezoelectric transducer (3) is connected with preamplifier (4), will come from sensor
Voltage signal amplification after input variable as single-chip microcontroller (5), the real-time change for the pressure that single-chip microcontroller calculating sensor transmits
Amount show that (numerical value set includes starting for the rate of fuel consumption by comparing with the numerical value that sets under different situations
The each gear stages of machine, if the fuel consumption rate in the case of full load conditions, idle conditions and parking).When single-chip microcontroller meter
To fuel consumption rate be much larger than the numerical value set when, it is known that engine occurs to steal oily phenomenon, at this time on display instrument (6)
The fuel consumption rate of display at this time, while alarm (7) is alarmed to remind driver, to reach the hair for preventing oily phenomenon steathily
It is raw.
