Description
Technical field
The present invention relates to a kind of Luggage Cart.
Background technology
Go-cart (Garden cart) is the carrying vehicle tried hard to recommend with people, draw, and it is the first ancestor of all vehicles.Although hand push
Car material handling technology development, but handbarrow is still used till today as indispensable handbarrow.Handbarrow is being given birth to
Produce and life obtain extensively application be because that it is cheap, safeguard be simple and convenient to operate, from heavy and light, can be at motor vehicles
The local work that inconvenience uses, very convenient when the article that short-haul operation is lighter.
And Luggage Cart includes several containing structures, containing structure is placed luggage, the most just can play and conveniently remove
Fortune effect, relatively conventional when waiting, and if user one-man, then if it needs just to leave Luggage Cart
Can more bother, and if by Left baggage equally can more inconvenience, but if directly off go-cart certain distance, may
The situation that luggage is stolen occurs.
Summary of the invention
In view of this, it is an object of the present invention to provide the Luggage Cart of a kind of automatic detection warning.
In order to solve above-mentioned technical problem, the technical scheme is that
A kind of Luggage Cart is provided,

Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in further detail, so that technical solution of the present invention is more
Should be readily appreciated that and grasp.
A kind of Luggage Cart 100, includes radio-frequency (RF) device 210, pressure transducer 231, and described radio-frequency (RF) device 210 adaptive is corresponding
The first radio-frequency coil 310, described first radio-frequency coil 310 and radio-frequency (RF) device 210 wireless connections, described radio-frequency (RF) device 210 is coupled with
One delay circuit 220, described pressure transducer 231 is coupled to a decision circuitry 230, and described decision circuitry 230 is coupled to an announcement
Alert device 240, when described radio-frequency (RF) device 210 is not detected by the first radio-frequency coil 310, the work of described delay circuit 220 timing, institute
Stating delay circuit 220 when working more than the first Preset Time, described decision circuitry 230 works and receives current pressure sensor
231 output voltages are as reference voltage, and when the output voltage of pressure transducer 231 changes, described decision circuitry 230 controls to accuse
Alert device 240 works.It is internal that first radio-frequency coil is arranged at a bracelet 300.One lock circuit, described lock circuit includes a setting
A sensor 250 at the wheel of described Luggage Cart 100, when described radio-frequency (RF) device 210 is not detected by the first radio-frequency coil,
Whether described sensor 250 works, rotate, such as vehicle wheel rotation, described biography with detection wheel under described sensor 250 duty
Sensor 250 sends signal control warner 240 and works.Communication module 260, when warner 240 works, described communication module
260 wireless transmission one warning signals.Every the second Preset Time, described radio-frequency (RF) device 210 detects whether first radio-frequency coil is deposited
Near being.
Making explanations firstly for mechanical structure portion, the structural requirement firstly for Luggage Cart 100 body has following
Part, if luggage truck ontological existence multiple use state, as a example by its normal condition, pressure transducer 231 should be placed
In the underface of its normal condition, and embedding setting, have two kinds of set-up modes, one is to arrange a total test point, and detection pushes away
The gross weight that car bears, two is that each storage space 110 is respectively provided with pressure transducer 231, and corresponding needs set
Put multiple decision logic to detect, when a storage space 110 occurs abnormal, it is judged that logic will outputting alarm signal,
Bracelet 300 can be to use the material that penetration loss is less to make, it is ensured that the electromagnetic induction of coil can receive interference, and
Warner 240 is preferably provided to buzzer.
Circuit hardware part makes detailed description, is first the setting of pressure transducer 231, and pressure transducer 231 can be selected
Electric current output and voltage export, for convenience of explanation, the present invention by voltage export as a example by, explain, and decision circuitry 230 to
Include a comparator and a depositor less, and the end that triggers of depositor is coupled at corresponding radio-frequency (RF) device 210 or delay circuit 220
On, when can't detect the first radio-frequency coil (or when delay circuit 220 counting overflows), send a pulse signal, such depositor
Respond this porch and remove to obtain the number of degrees of a pressure transducer 231, it is noted that these number of degrees, as the benchmark number of degrees, are used for
Follow-up comparison, namely when people leaves, records the weight of current luggage automatically, and if weight changes, then in time
Prompting user notes, and the comparison of weight is realized by comparator, comparator can be digital comparator can also be simulation
Comparator, is converted the conversion realizing between comparator, compares by digital-to-analogue, it should be noted that preferred version is to arrange
One reference range, such as benchmark data are 50KG, then can be that 49.5KG-50.5KG is stolen all without can be regarded as luggage, this
Sample is arranged, and prevents because circuit error causes the situation of false alarm, and radio-frequency (RF) device 210 includes a transmitting coil and a receiving coil,
Two coils work simultaneously, and transmitting coil launches the magnetic field of corresponding frequency band, and this magnetic field is for sensing the first radio-frequency antenna, and passes through
The current signal that receiving coil receives judges, so, it is possible to realize the detection of corresponding frequency band, and delay circuit
The setting of 220, can be that enumerator couples radio-frequency (RF) device 210 by the Enable Pin of enumerator, it is possible to realize radio-frequency (RF) device 210
Data acquisition；Regulation enumerator connects the value of depositor, it is possible to configuration delay time, for detecting the sensor of vehicle wheel rotation
250 could be arranged to any one in orthogonal encoder, damper switch, displacement transducer 250, as long as go-cart can be detected are
No rotate, the power end of sensor 250 is accessed the outfan of radio-frequency (RF) device 210, when radio-frequency (RF) device 210 is not detected by coil
Time, export the state of a control signal locking moment sensor 250, then, if the state of sensor 250 changes, that
All can be judged as exception, with regard to outputting alarm signal, and the setting of communication module 260, can be the nothing such as ZIGBEE, bluetooth
Line communication modes, is connected directly to service centre, reminds airdrome control personnel to notice that lost article is pursued in cooperation.
Certainly, being more than the representative instance of the present invention, in addition, the present invention can also have other multiple to be embodied as
The technical scheme that mode, all employing equivalents or equivalent transformation are formed, within all falling within the scope of protection of present invention.
