Embodiment
As shown in Figure 1, a kind of greenhouse corps stem stalk, fruit size measurement wireless acquisition system have a folding baffle 9 and pedestal 3, the top of pedestal 3 is connected by rotating shaft 8 with one end of folding baffle 9, in pedestal 3, an expansion link 7 is installed, a laser head 10 is installed on the top of expansion link 7, expansion link 10 moves up and down along the inside of pedestal, and the top of pedestal 3 is provided with the groove 1 matched with laser head 10, for the protection of laser head; Laser head 10 connects a controller, controller connects liquid crystal display 5 and a wireless communication module, pedestal is provided with level meter 4 and sends button 6, send button 6 to be connected with controller, be sent to computing machine by wireless communication module after the data processing that laser head 10 collects by controller, described controller, liquid crystal display and wireless communication module are arranged on pedestal 3.
Pedestal 3 is provided with LED 2, ensures that level meter still can use in the environment of illumination condition difference by LED 2.
The cross section of expansion link is rectangle or square, ensures when measuring, contact site level.
Laser head in the present embodiment is for adopting phase type principle of work, range ability 0.15-30m, precision ± 2mm, minimum indicating range 0.1mm, laser levels: class2,635nm, <1mW, operating voltage 12-15V, data-interface: RS232/RS485/ electric current loop.
Controller adopts single-chip microcomputer, and the distance measuring sensor in laser head is connected with single-chip microcomputer by RS232 data-interface, and laser head measuring distance, to the corresponding connection pin of single-chip microcomputer, is passed to single-chip microcomputer by laser head output switch amount or level signal.Liquid crystal display adopts LCD liquid crystal display, reduces LED and shows high energy consumption problem, and single-chip microcomputer is by each pin of signal wiring LCD liquid crystal display, and single-chip microcomputer is presented on LCD liquid crystal display by needing the distance of display, and wherein LCD liquid crystal display is arranged on laser head.
The course of work: as shown in Figure 2, opens folding baffle, and object under test at right angles, is put on folding baffle by folding baffle and contact portion, and folding baffle blocks object being measured one side, and contact portion blocks object being measured.Level meter judgment means is utilized to keep horizontality.By slowly moving telescopic pipe, laser ranging part is opened gradually, and opening speed is lower than 10m/s, and people's stretch laser ranging unit speed is far below 10m/s.First to be aimed at the mark Emission Lasers pulse by the laser diode in laser head, after target reflection, laser is to all directions scattering, some scattered light turns back to the transducer receivers of laser head, to be imaged onto in laser head on distance measuring sensor after being received by optical system, distance measuring sensor can with 0.1s response time read data, single-chip microcomputer can adopt differential analysis algorithm display measurement distance according to laser range sensor forward data, differential analysis algorithm is as follows: set the distance of reading at present as S, the distance of reading in before 0.1s is s, as (S-s) >s, the value of display s, otherwise do not show.
Distance measuring sensor adopts on avalanche photodide, avalanche photodide is a kind of optical sensor with enlarging function, it can detect extremely faint light signal, records and process to be issued to from light pulse to return received the experienced time, thus can measure target range.
Differential analysis algorithm principle, according to crops stem stalk diameter and blade face length feature symmetrically, as shown in Figure 3, laser head distance measuring sensor from bottom to top one-time detection distance is S1, S2, S3.Clearly find out S1, S2 is the distance measuring object being measured, and S3 is the distance measuring non-object being measured.Computing machine judges object being measured last length by difference comparsion, i.e. object being measured radius.Namely (S2-S1) <S1, gives up, does not show, (S3-S2) >S2, retains, display S2 measuring distance.
Pedestal is provided with transmission button, send button to be connected with single-chip microcomputer, after Send button, single-chip microcomputer sends to far-end radio receiver by wireless communication module measuring distance, and shown on computers by RS-232 and preserve, can according to the concrete length sequence of time-sequencing by record.Wireless communication module adopts nRFID or wireless sense network or WIFI module or GPRS module or CDMA20001X or WCDMA or TD-SCDMA or TD-LTE, FDD-LTE or 5G.
