Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and embodiments.
The main body of the present invention is the method for a set of dot matrix material detection realized based on CPLD and feeding instruction of design
And intelligent apparatus.CPLD is working centre, and realization communicates with radio node, material detects, feeding instruction three parts function.With nothing
The communication of line node can use serial ports, be simple and efficient；Material detects and feeding instruction is two sets of standalone features, and it is different to occupy CPLD
Controlling switch.Material detection unit is a set of lattice structure made according to material frame actual size with cable, each ranks
There are one detection device on crosspoint, for detecting the material stock of each position on material frame.Feeding indicates single with material detection
Meta structure is similar and one applies mechanically the lattice structure that cable is made, and there are one indicator lights on each ranks crosspoint.Dot matrix object
The structure diagram of material detection and feeding indicating intelligent device is as shown in Figure 1.
The present invention using one piece of CPLD chip (take into account cost according to actual needs, can also use microcontroller or other
The CPU of low cost), realize that the detection of dot matrix material and feeding indicate two kinds of functions.The principle of CPLD type selectings is：Common pin number
Amount is more than 2 times of material frame ranks sum, and the internal logic resources such as register, macroelement meet design requirement, can correctly compile
It translates, integrate, download.
Function is described in detail by specific example of 4 × 4 array material frames below.
CPLD occupies one group of pin, respectively as row, column two parts (ranks can random quantity, be not necessarily intended to equal),
Part pin is arranged as output, controls the break-make of one group of triode (metal-oxide-semiconductor or relay can also be selected according to actual needs)；
The collector of triode is uniformly connected on power supply.Row part pin is sent into CPLD, the intersection of each ranks as input signal
Point connects a detection device, the detection sensor as position each on material frame.Detecting device can be according to detected material
State and flexibly select.If scattered gadget part, pressure-strain piece can be selected, judge that material remains according to weight
It is remaining, while an adjustable resistance is concatenated on each detection row, alarming threshold can be adjusted flexibly；If big part material, then
It can be selected close to switch, judge whether each position has material.
Dot matrix material testing principle is：CPLD controls output pin, only opens the triode of a row every time, and simultaneously
Scan the state of each row.For using pressure-strain piece as detection device, when corresponding position material is enough on material frame,
Weight is bigger, and foil gauge resistance is smaller, and the row pin is equivalent at this time is pulled upward to power supply by a low resistance, and CPLD draws
Foot reads high level, and the state of each row is completely independent, and the material of the upper all positions of a row can be perceived by single pass
Situation；If some position material surplus is smaller, weight, then sheet resistance is strained at this time to become larger, the work of pull-up
With dying down, the effect of adjustable resistance drop-down becomes strong, and judgement threshold can be adjusted by adjusting variable resistance.When the surplus of material becomes
It is small to cause to strain sheet resistance reach judgement threshold when, CPLD pins will read low level, and CPLD perceives corresponding position and lacks
Material generates and alerts and be sent to radio node.On radio node is then uploaded onto the server alarm by wireless sensor network
Display.
The principle of dot matrix feeding indicating means is：CPLD occupies one group of row pin and one group of row pin respectively, all
It is used as output signal.Each output pin controls a triode (can also select metal-oxide-semiconductor or relay according to actual needs
Device) break-make, the collector of row pin control triode connects power supply, the emitter ground connection of row pin control triode.Work as needs
When the indicator light of some position is lighted on material frame, it is only necessary to two triodes of row/column corresponding position open simultaneously,
Pilot lamp power and ground form access and can light at this time.
In addition, a master pilot lamp and a charactron are also attached on radio node.When the quantity of material frame in storehouse
When comparing more, the master pilot lamp of material frame is chosen to light, neck material people is prompted first to find material frame, looks for certain on material frame again later
One position.Neck material quantity is shown on charactron.When once needing to get various materials, poll shows the position that need to get material
It puts and quantity.Specific work process is：Operating personnel choose the title and quantity of material to be got, neck material order on the server
Counterpart rack is issued to by wireless network, radio node control master pilot lamp is lighted on material frame, at this time material frame first
Kind material position indicator is lighted and is flickered, the first quantity that get material is shown on charactron.Neck material people by quantity and
After position indicating neck material, button on radio node is clicked, then the first material indicator light extinguishes, second of material position
Indicator light is lighted and is flickered, while shows that second of material gets quantity on charactron.This process poll, until all materials are all
After neck material, indicator light and charactron all extinguish.
Communication data message is subject to simple, reliable between CPLD and radio node.The hardware configuration of apparatus of the present invention can
Using the message length for considering to communicate every time as a byte.Wherein, first 4 represent row data, and latter 4 represent column data, each
Position full 0/complete 1, which is stayed, does debugging use.The structure of communication message is shown in attached drawing 2.4 binary row/column address in one byte, remove
Full 0/complete 1 retains debugging and uses, and position ranks are up to 1110, can at most represent 14 × 14 times since 0001 on material frame
Row material frame can meet the actual demand of most model material frames substantially.If CPLD is to radio node transmission data
0x11 represents material detection unit and detects that the first row first row generates alarm on material frame, and the position material surplus is insufficient.Such as
Fruit radio node is to CPLD transmission data 0x11, then representing needs to light the first row first row position indicator, if wireless section
Point then lights whole indicator lights to CPLD transmission data 0xFF.If radio node extinguishes complete to CPLD transmission data 0x00
Portion's indicator light.
The property rack of same storehouse connects into a wireless sensor network by radio node.Applied to storehouse object
The networking of the wireless sensor network of rack is as shown in figure 3, by a radio network gateway (if apart from far blocking and can also increase
AP ensures reliable data transmission) convergence data, server is sent to by cable.Server can be positioned over Office Area, and realization is done
