Fig. 1 forms structural representation for the utility model;
Fig. 2 is a classification container structural representation of the present utility model;
Fig. 3 has the funnel synoptic diagram of infrared receiving/transmission to pipe for the utility model;
Fig. 4 is the circuit theory diagrams of the utility model signal processing circuit board.
Embodiment
Fig. 1 is the composition structural representation of the utility model sealed seed source activity differential count equipment, and as shown in Figure 1, this equipment includes classification container 1, signal processing circuit board 2, counter 3 and computing machine 4.
Fig. 2 is the classification container structural representation, and as shown in Figure 2, described classification container is special classification container that can the source electromagnetic radiation of shield gasket seed, comprises upper strata container 5 and lower floor's container 6 with uniformly-spaced.In lower floor's container 6, Fen Lei categorical measure as required, lower floor's container 6 is isolated into equally spaced several little storehouses, can place the cillin bottle 8 that stores sealed seed source in these little storehouses, and classification described here is meant selected in advance as required range-of-motion.Upper strata container 5 comprise with the little storehouse compartment corresponding, equivalent amount of lower floor container 6 every, but funnel channel 7 is made in each upper end at interval, tubular conduit is made in the lower end, and upper and lower end constitutes the passage of a connection jointly, and tubular conduit is directly inserted in the cillin bottle 8.Each sealed seed source of test through activity meter can be poured directly in the funnel channel 7 of upper strata container 5 of corresponding range-of-motion, so that sealing seed source waltzs through upper strata container 5, in the cillin bottle 8 of arrival lower floor container 6.
Fig. 3 has the funnel synoptic diagram of infrared receiving/transmission to pipe, as shown in Figure 3, tubular conduit at upper strata container 5, two apertures that are provided with along radial symmetry, so that place by infraluminescence pipe and infrared receiving tube forms to pipe, be used for detecting sealed seed source whether by and which organizes funnel channel by.
Fig. 4 is the circuit theory diagrams of a paths of signal processing circuit board, the little storehouse of each of corresponding classification container, and the circuit of every paths is identical.As shown in Figure 4, described signal processing circuit board includes electric signal and produces circuit and electric signal shaping circuit; This electric signal produce that circuit includes that outer luminotron LED1 and infrared receiving tube PHOTO1 constitute to manage, triode TR1 and resistance etc.; The above-said current signal shaping circuit comprises Schmidt trigger, and this Schmidt trigger is made of jointly three inverter ic 1A, IC1B, IC1C and resistance R 4, capacitor C 2.Wherein, capacitor C 2 is used for the counter-rotating of acceleration pulse, and resistance R 4 is the triggering feedback resistance of Schmidt trigger.The infrared tube that infraluminescence pipe LED1 and infrared receiving tube PHOTO1 constitute among Fig. 4, be used for detecting sealed seed source and whether pass through and pass through any group funnel channel, resistance R 1 is the biasing resistor of infrared transmitting tube among Fig. 4, and resistance R 2 is the biasing resistor of infrared receiving tube.
Under normal circumstances, when not having sealed seed source to pass through this funnel channel 7, infrared receiving tube PHOTO1 conducting, thus make triode TR1 base stage and emitter be in high level state, this moment socket P2 output low level, the digital counter at rear is not counted.And when sealed seed source during by described funnel channel 7, the sealed seed source that the infrared light that infraluminescence pipe LED1 sends was passed through by moment stops and cuts off, thereby infrared receiving tube PHOTO1 is ended, and produce the electric pulse of a negative sense in the base stage of triode TR1, because speed and the influence such as position of sealed seed source by funnel channel 7 lower ends, the width of this electric signal and amplitude are very irregular, can not be directly used in actuation counter.Because the effect of this negative pulse makes triode TR1 end, at this moment, emitter capacity C1 at triode TR1 discharges by resistance R 3, thereby the emitter at triode TR1 has also formed a negative pulse, the pulsewidth of this negative pulse is determined by time constant (R3*C1), above-mentioned negative pulse is sent to Schmidt trigger and carries out the shaping processing, formation can be discerned by the digicounter at rear, the positive pulse electric signal that pulse width and the input of amplitude coincide counter require, this positive pulse electric signal is sent into the digicounter at rear by socket P2, and this counter writes down and adds up according to the sealed seed source of the positive pulse signal of receiving to corresponding activity.
The quantity of above-mentioned digicounter class categories as required, set several input ports, the corresponding one group of container that need classify of each input end, so that to each class is that the sealed seed source quantity of each range-of-motion is counted, this counter is added up the data of classification according to classification after receiving above-mentioned counting automatically, and on the screen of counter front, directly show, what the screen left of counter showed is class code, right-hand demonstration be such other quantity statistics, meanwhile, the statistic of classification result of counter is imported in the computing machine at rear by communication port.
The digicounter recorded data, import the computing machine that the exclusive data library software that is used for the statistic of classification record is installed into by communication port, this software is after the data that receive the digital counter input, data are analyzed according to the different range-of-motion of setting, ordering, be kept in the sealed seed source taxonomy database, with distinctive file layout the classification of sealed seed source classification, the quantity of a certain classification sealed seed source, total quantity, and measure date etc. and have related parameter to be presented on the screen, preserve computing machine, and can call at any time according to user's needs, print this record.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
