Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
The present invention includes the paper money device fault monitor module of automatic vending generator terminal, shipment device monitoring module, the monitoring of card goods
Module, small change fault monitor module, small change storage fault monitor module, motor operating state monitoring modular, main board failure monitoring
Module, host-processor and LoRa module further include LoRa gateway, local area network and the Vending Machine at background monitoring end

Small change storage fault monitor module, motor operating state monitoring modular and main board failure monitoring modular are all connected to host process
Device, host-processor pass through LoRa module again and are wirelessly connected LoRa gateway, and LoRa gateway is connected by local area network automatic again
Vending machine monitoring center.
The paper money device fault monitor module includes that bank note import detection device for foreign matter and cash box are put in place detection dress
It sets, for detecting bank note import foreign matters from being blocked situation, cash box is put in place detection device and is used for bank note import detection device for foreign matter
Detection cash box is installed in place situation.The lamp of paper money device mouth do not work or it is suddenly bright neglect it is dark；It is put into bank note, machine does not inhale money inward.
Paper money device failure cause: there is foreign matter in 1. paper money devices.2. iron cash box is fitted without under paper money device.So this
Invention, bank note import detection device for foreign matter carry out the alarm on backstage, solution party for detecting bank note import foreign matters from being blocked situation
Method is that the person of sending someone opens paper money device, is shut down after removing foreign matter, then be switched on.Cash box is recycled to be put in place detection device for examining
That surveys cash box is installed in place situation, alarm to backstage, service personnel by closing machine power supply, reinstall iron cash box with
It solves the problems, such as.
The shipment device monitoring module uses goods control jogging switches measurement device, connects for detecting goods control microswitch
Touch situation.Shipment failure, which refers in refrigerating box, cargo but machine thinks out of stock, passes through shipment device monitoring module, detection
Whether goods control microswitch is seen in poor contact or failure.
The card goods monitoring modular includes that shipment spring starting point is examined to level detecting apparatus and cargo effluent specification position
Device is surveyed, shipment spring starting point to level detecting apparatus is for detecting shipment spring starting point situation in place, i.e. shipment spring shape
Whether normal become；Cargo effluent specification position detecting device is used to detect the cargo of neat situation and placement that cargo discharges
Whether size meets specification of getting in stocks.Commodity block, can not normal shipment.
Card goods failure cause: using spring spiral cargo path, in machine shipment, spring rotation commodity can be generated it is positive or
Slanting extruding force.Under the action of forward extrusion power commodity be easy it is askew fall, even fall down, will lead to commodity card in this way and exist
Below cargo path (below spring).It will increase the frictional force between commodity and cargo path two sides backplate under the action of oblique compression power,
Will lead to commodity when frictional force is larger cannot normal shipment.So by shipment spring starting point to level detecting apparatus and
Cargo effluent specification position detecting device is detected, is alarmed.Solution: the commodity blocked are taken out, automatic vending is entered back into
Machine administration page removes card goods failure.Corresponding change is made to putting for commodity in later operation, the size of commodity will be use up
May be consistent with cargo path size, too small it can not be greater than cargo path spring sizes and fill in firmly.
The small change fault monitor module includes change storage amount detecting device, small change device blockage detector and coin
Identifier cleannes detection device, change storage amount detecting device is used to detect the current surplus of change in small change device, when surplus
When surplus is lower than setting value, alarm signal is sent；Small change device blockage detector is examined for detecting foreign matter situation in small change device
It whether surveys by foreign matters from being blocked；Whether Coin validator cleannes detection device is clean for detecting Coin validator, if not doing
Only, the recognition performance failure of Coin validator.After shipment, small change but not small change are needed.
Small change failure cause: without change in 1. small change devices.2. have change in small change device, can default change number be in system
Zero.3. small change device card coin.4. Coin validator dust is too serious.So it is stifled to store amount detecting device, small change device by change
Plug detection device and Coin validator cleannes detection device are detected in real time, are alarmed, and solution: 1. supply change.
2. entering the system administration page, check whether last time has mended after change without record (after the automatic vending machine having has mended change
Need to be manually entered and fill into change number), if quantity is 0, please modify.3. dismantling coin device takes out the coin blocked.4. using
Gauze cleans up the dust in Coin validator channel, monthly clears up more than once.
The small change storage fault monitor module is for detecting paper money device operating time, if being more than setting operating time,
Then automatically reset.The change of investment does not enter in small change device, deposits into collect money in area instead.
Small change stores failure cause: paper money device fails shutdown rest for a long time, leads to paper money device system mistake.So this
Invention small change stores fault monitor module and detects paper money device operating time, if being more than setting operating time, automatically resets.Solution
Certainly method: after shutdown, enter the system administration page after booting three minutes, carried out with the reset key that a small rod gos deep into paper money device
(be inserted into after small rod pins reset key, can see after the lamp of paper money device mouth is first bright and go out, last and bright just loose one's grip) is resetted, is waited several
It shuts down, is turned back on again substantially with regard to solving the problems, such as after minute.
The motor operating state monitoring modular then needs to examine for prompting the cargo name invalid when detecting normal shopping
Survey corresponding motor assembly whether failure or the contact of relevant connecting line it is whether good.Corresponding motor assembly failure or relevant
Connecting line poor contact, solution: replacement motor assembly checks relevant connecting line.
The main board failure monitoring modular for flood pallet prompt cargo name when detecting normal shopping in vain or just
Often multiple layer tray prompt cargo name is invalid when shopping.The small pinboard connecting line of mainboard drive part failure or pallet contacts not
It is good, method: check relevant connecting line and mainboard drive part.The pinboard linkage fault of main board failure or mainboard, method:
Check the connecting line of main board failure and mainboard to pinboard.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or carries out to part of technical characteristic
Equivalent replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should all include
Within protection scope of the present invention.
