Abstract
The utility model discloses a kind of automatic vending machine shipment detection means, it is characterised in that described shipment detection means includes two groups of infrared emission reception pipes, respectively with corresponding MCU connections；The signal that described MCU is sent by being transmitted after modulation /demodulation to another MCU, meanwhile, the signal on both sides directly passes through order wire and carries out bi-directional synchronization and transmission；The signal that two groups of described MCU are sent is the signal of two groups of different frequencies, this programme passes through the modulating and demodulating signal to two groups of different frequencies, interference can largely be reduced, in addition, two groups of signals launch reception simultaneously, and signal can be covered preferably, reduce scan blind spot, the smaller shipment commodity of volume can be more accurately detected, while sweep speed can also be greatly improved.
Description
Technical field
The utility model belongs to detection of electrons and technical field of automation, is related to a kind of automatic vending machine shipment detection dress
Put.
Background technology
At present, disclosed automatic vending machine is typically without shipment detection means, and automatic vending machine is after the completion of shipment action
Bales catch if shipment is unsuccessful, easily triggers customer complaint except the purchase amount of money, be unfavorable for the development of automatic vending machine with it is general
And.Minority possesses the vending machine of shipment detection, and detection sensitivity is low, poor reliability, reports testing result by mistake, and same easily trigger is used
Complain at family.
Utility model content
The technical problems to be solved in the utility model, which is to provide, a kind of has that detection speed is fast, strong interference immunity, reliability
Device high, for automatic vending machine shipment detection.
In order to solve the above-mentioned technical problem, the utility model provides a kind of automatic vending machine shipment detection means, its
It is characterised by, described shipment detection means includes two groups of infrared emission reception pipes, respectively with corresponding MCU connections；Described
The signal that MCU is sent by being transmitted after modulation /demodulation to another MCU, meanwhile, the signal on both sides directly pass through order wire carry out it is double
To synchronous and transmission；The signal that two groups of described MCU are sent is the signal of two groups of different frequencies.
Further, two groups of described MCU signals are launched and received simultaneously.
Further, the line synchro between two groups of described MCU and order wire share.
Shipment detection means of the present utility model is located at the both ends for the position for needing to detect commodity shipment, automatic for detecting
Whether article delivery mechanism for vending machine accurate judgement after the shipment instruction that automatic vending machine main control unit sends is received has commodity to go out
Goods, and testing result is fed back into automatic vending machine main control unit, the present apparatus passes through the signal modulation solution to two groups of different frequencies
Adjust, can largely reduce interference, in addition, two groups of signals launch reception simultaneously, signal can be covered preferably, and it is blind to reduce scanning
Area, the smaller shipment commodity of volume can be more accurately detected, while sweep speed can also be greatly improved.
Brief description of the drawings
Fig. 1 is schematic block circuit diagram of the present utility model.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be with
More fully understand the present invention and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
The embodiment of the utility model one provides a kind of automatic vending machine shipment detection means, referring to Fig. 1, MCU1 is sent
A frequency signal by launching after multiway analog switch through infrared transmitting tube, after infrared receiving tube receives, through multi-channel analog
MCU2 is sent to after switch modulation demodulation, meanwhile, the signal that MCU1 is sent passes through order wire synchronizing signal to MCU2；Equally,
After the signal for another frequency that MCU2 is sent after multiway analog switch by launching through infrared transmitting tube, infrared receiving tube receives,
MCU1 is sent to after multiway analog switch modulation /demodulation, meanwhile, the signal that MCU2 is sent by order wire synchronizing signal extremely
MCU1, the signal that described MCU1 and MCU2 are sent are the signal of different frequency.
This programme is transmitted by way of modulation /demodulation using the signal of two kinds of different frequencies, is greatly reduced outer bound pair
The possibility of detection signal interference, reduce the rate of false alarm of detection, reliable detection hand is provided for the shipment of automatic vending machine
Section.
In addition, this programme uses two set detecting devices, while transmitting and reception signal, signal can be covered preferably, be reduced
Scan blind spot, the smaller shipment commodity of volume can be more accurately detected, while sweep speed can also be greatly improved.
