Fig. 2 illustrates the workflow of card reader, and as shown in the figure, flow process is as follows:
S201: hardware initialization;
S202: judge whether to produce and interrupt, no, then continue to judge, be then perform S203, S209 and S221 simultaneously;
S203: radio frequency disruption;
S204: resolution reply message;
S205: inquire about all tag commands;
S206: structure radio-frequency command makes single label mourn in silence;
S207: turnover label information;
S208: be uploaded to backstage, returns S202 afterwards and continues to judge whether to produce to interrupt;
S209: serial ports interrupts;
S210: resolve serial port command;
S211: whether sound and light alarm order occurs, is, then jump to S224 and perform and send alerting signal, and return S202 and continue to judge whether to produce and interrupt;
S212: whether inquire about all tag commands, be, then jump to S214 and perform that to arrange emitting times be 3, no, then continue to perform S213;
S213: arranging emitting times is 1;
S215: structure radio-frequency command;
S216: setting time-out time;
S217: send order;
S218: emitting times is for subtracting 1;
S219: judge that whether timer is overtime, no, then continuing to return S219 and judge, is then jump to S220;
S220: judge whether transmission times is greater than 0, is, then return and continue to perform S215, no, then return S202 and continue to judge whether to produce to interrupt;
S221: infrared sensor interrupts;
S222: judge turnover direction;
S223: label near the inquiry of structure radio-frequency command, returns S202 and continues to judge whether to produce to interrupt.
In order to the site requirements making this system can adapt to different area size, the emissive power of label can regulate, meet the needs of different distance, the emissive power of the label in native system has four grades that can regulate, and is respectively 10dBm, 0dBm ,-6dBm ,-12dBm.
The concrete function that system can realize:
(1) the automatic collection of material information and inquiry
A label is distributed to each equipment, and label is pasted onto equipment surface, the simultaneously relevant information of the equipment corresponding to ID of this label of typing in background data base, as: device name, unit type, equipment purchase producer, equipment correlation parameter etc., and set a safe working temperature scope in background system each equipment, by inquiring about the ID of this equipment institute tape label at background monitoring center, the relevant information of equipment can be grasped comprehensively; When the information (positions as goods and materials) of goods and materials changes to some extent, the details collection of goods and materials can be come up by being installed on on-the-spot card reader.
(2) material equipment running temperature monitoring
Label is connected with temperature sensor, this temperature sensor is close to equipment surface, when the apparatus is in operation, the temperature information that temperature sensor collects by label passes to card reader, card reader borrows group and communication module that the temperature of equipment is passed to background monitoring system by zigbee network again, background monitoring system stores the device temperature value gathered and analyzes, apparatus for establishing Temperature Distribution and change procedure model, thus the running status of analysis and monitoring electrical equipment, when discovering device temperature anomaly (exceed setting mxm. or lower than setting minimum time), then start the audible-visual annunciator warning that card reader connects.
(3) goods and materials illegally take monitoring out of
In the porch in regulation region, in sequence two pairs of infrared emission devices are installed, specifically as shown in Figure 3.When goods and materials are as taken out from the region of regulation, need and keeper's contact, this equipment is set as outbound state by keeper, sends dependent instruction to the card reader at this area entry place (this instruction should include No. ID of label), after card reader receives this instruction simultaneously, even if when recognizing this equipment for taking out of, also do not restart warning system, meanwhile, background management system will record the borrower of this equipment, borrowing time etc., and form related statements.If just equipment not to be taken out of the region of regulation through the agreement of keeper, then background management system is by judging the signal that the infrared emission device being installed on on-the-spot porch is sent, think that this equipment is illegally taken out of, then start the audible and visual alarm system of the card reader connection being installed on porch.
(4) goods and materials navigate to room
In the present system, each card reader also has self a numbering, card reader is while Transport label information, also the numbering of self can be passed to background management system, therefore, when system is installed at the beginning, record room number corresponding to each fixed reader or region in systems in which, background management system can determine room residing for the goods and materials that label is pasted or concrete belonging positions according to the numbering of card reader sending this label information.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that performing creative labour can make still within protection domain of the present utility model.
