Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The main body of the present invention is a set of method based on the CPLD dot matrix material realized detection and feeding instruction and the intelligent apparatus of design.CPLD is working centre, it is achieved indicate three partial functions with radio node communication, material detection, feeding.Serial ports can be used, simply efficiently with radio node communication；Material detection and feeding instruction are two set standalone features, take control pins different for CPLD.Material detection unit is a set of lattice structure made according to material frame actual size cable, each ranks cross point has a detection device, for detecting the material stock of each position on material frame.It is similar that feeding instruction detects cellular construction with material, is also apply mechanically the lattice structure that cable is made, each ranks cross point has a display lamp.The structural representation of the detection of dot matrix material and feeding indicating intelligent device is as shown in Figure 1.
The present invention adopts one piece of CPLD chip (taking into account cost according to actual needs, it would however also be possible to employ the CPU of single-chip microcomputer or other low costs), it is achieved the detection of dot matrix material and feeding two kinds of functions of instruction.The principle of CPLD type selecting is: common pin quantity is more than 2 times of material frame ranks sum, and the internal logic resource such as depositor, macroelement meets design requirement, it is possible to correct compiling, comprehensive, download.
Function is described in detail for instantiation below with 4 × 4 array material frames.
CPLD takies one group of pin, respectively as row, column two parts, (ranks can random quantity, it is not necessarily intended to equal), row part pin, as output, controls the break-make of one group of audion (can also select metal-oxide-semiconductor or relay according to actual needs)；The colelctor electrode of audion is unified to be connected on power supply.Row part pin sends into CPLD as input signal, and the cross point of each ranks connects a detection device, as the detection sensor of position each on material frame.Detection device can select flexibly according to the state of detected material.If scattered gadget part, can be selected for pressure-strain sheet, judge that material remains according to weight, simultaneously each detection row one adjustable resistance of upper concatenation, it is possible to adjust alarming threshold flexibly；If big part material, then can be selected for proximity switch, it is judged that whether each position has material.
Dot matrix material Cleaning Principle is: CPLD controls output pin, only opens the audion of row every time, and scans the state of each row simultaneously.For pressure-strain sheet as detecting device, when on material frame, correspondence position material is abundant, weight is relatively larger, foil gauge resistance is smaller, now this row pin is equivalent to be pulled upward to power supply by a small resistor, CPLD pin reads high level, and the state of each row is completely independent, and perception one can arrange the material situation going up all positions by single pass；If some position material surplus is smaller, then weight, then now foil gauge resistance becomes big, and the effect of pull-up dies down, the drop-down effect of adjustable resistance becomes strong, can adjust judgement threshold by adjusting variable resistance.When the surplus of material be varied down to cause that foil gauge resistance reaches judgement threshold time, CPLD pin will read low level, and CPLD perception correspondence position lacks material, produces alarm and is also sent to radio node.Alarm is then uploaded onto the server upper display by radio node by wireless sensor network.
The principle of dot matrix feeding indicating means is: CPLD takies one group of row pin and one group of row pin respectively, all uses as output signal.Each output pin controls the break-make of an audion (can also select metal-oxide-semiconductor or relay according to actual needs), and row pin controls the colelctor electrode of audion and connects power supply, and row pin controls the grounded emitter of audion.When needing that on material frame, the display lamp of some position is lighted, it is only necessary to two audions of row/column correspondence position are opened simultaneously, now pilot lamp power and ground form path and can light.
Additionally, radio node has also attached a master pilot lamp and a charactron.When the quantity of material frame is more in storehouse, choosing the master pilot lamp of material frame to light, prompting neck material people first finds material frame, looks for some position on material frame afterwards again.Charactron shows neck material quantity.When once needing to get various materials, poll shows the position and quantity that need to get material.Specific works process is: operator choose the title and quantity that to get material on the server, neck material order is issued to homologue bin by wireless network, on material frame, radio node control master pilot lamp is lighted, now the first material position indicator of material frame is lighted and glimmers, and charactron shows the first to get the quantity of material.Neck material people, by after quantity and position indicating neck material, clicks button on radio node, then the first material display lamp extinguishes, and the second material position indicator is lighted and glimmers, and shows that quantity got by the second material on charactron simultaneously.This process poll, until all materials are all led after material, display lamp and charactron all extinguish.
Between CPLD and radio node communication data message with simple, be reliably as the criterion.The hardware configuration of apparatus of the present invention can consider that the message length of communication every time is a byte.Wherein, first 4 represent row data, and latter 4 represent column data, and each full 0/complete 1 is stayed and done debugging use.The structure of communication message is shown in accompanying drawing 2.4 binary row/column address in one byte, removing full 0/complete 1 and retain debugging use, on material frame, position ranks are from 0001, are up to 1110,14 × 14 array material frames can be represented at most, substantially can meet the actual demand of most model material frame.If CPLD sends data 0x11 to radio node, representing material detection unit and detect that on material frame, the first row first row produces alarm, this position material surplus is not enough.If radio node sends data 0x11 to CPLD, then represent and need to light the first row first row position indicator, if radio node sends data 0xFF to CPLD, then light whole display lamp.If radio node sends data 0x00 to CPLD, then extinguish whole display lamp.
The property bin of same storehouse connects into a wireless sensor network by radio node.It is applied to the networking of the wireless sensor network of storehouse material frame as it is shown on figure 3, converged data by a radio network gateway (if distance is far blocked can also increase AP guarantee reliable data transmission), delivers to server by cable.Server can be positioned over Office Area, it is achieved the physical isolation in Office Area and storage region, is beneficial to management.
Top service device interface adopts VC or VB programming tool to complete.As long as there being material position to input, neck material operates button and basic debugging function, it is proposed that the design interface pattern of reference is as shown in Figure 4.Input name of material and position (form is pressed in the input of material position: material frame number: line number: row form, such as 1:1:1), click " input of material position ", be saved on the hard disk of server by this data content.Every kind of material has only to once input, it is possible to continuously perform the operation of material position input.Neck material operation only need to provide name of material and quantity, clicks " neck material ".Neck material order can be issued to material frame correspondence position, it is possible to continuously performs neck material operation, it is achieved once multiple neck material.Lead name of material when expecting can click drop-down menu to choose, it is also possible to manually enter.Manually enter support fuzzy search, namely simply enter that a character satisfies condition all displayed below, quantity can arbitrarily be filled in.It is alarm display window below interface, it is possible to show a plurality of simultaneously.If a screen shows not open, next alarm replaces a upper alarm automatically.Additionally, interface arranges several attached button, use for commissioning device.
