Summary of the invention
The present invention seeks to provides a kind of digital display type fish body biology analyzer to the defective of prior art.
The present invention adopts following technical scheme for realizing above-mentioned purpose:
Digital display type fish body biology analyzer is characterized in that: comprise linear measure longimetry unit, weight weighing unit, LCDs, function key, single-chip microcomputer and data-interface, wherein:
LCDs is used to show various measurement data and operating procedure;
Function key is used for functions such as length of handover measurement, weight weighing, storage data;
Single-chip microcomputer is used to handle keyboard instruction, and accomplishes the instruction by Keyboard Control;
Data-interface is used for carrying out the exchanges data transmission with external equipment.
Said digital display type fish body biology analyzer is divided into two-layer up and down, and the upper strata is the linear measure longimetry unit, and it is whole simultaneously as the tray portion of weight weighing unit, and lower floor is the miscellaneous part of weight weighing unit.
Said linear measure longimetry unit comprises capacitor grid transducer, scale, slip chi, pointer, and an end of said pointer is fixed in an end of said slip chi, and can on the plane perpendicular to the slip chi, do 180
oRotation.
Said function key comprises length storage key, weight storage key, zero setting key, peeling key, property key, completion key, switch key, clear key.
Said data-interface is a USB interface.
The present invention has advantage:
1, in fish body biology measuring process, only needs one man operation, do not need recorder and data entry operator, save manpower.
But 2, the rotatable pointer assist location of slip chi one end, thereby reduce the terminal formed error that human eye is judged measurement target.
3, can avoid human errors such as slip of the tongue, survey measurements error, misregistration or typing mistake, improve the accuracy of data.
Embodiment
A kind of as shown in Figure 1 digital display type fish body biology analyzer is characterized in that: comprise linear measure longimetry unit 1, weight weighing unit 2, LCDs 3, function key 4, single-chip microcomputer and data-interface, wherein:
LCDs 3 is used to show various measurement data and operating procedure;
Function key 4 is used for functions such as length of handover measurement, weight weighing, storage data;
Single-chip microcomputer is used to handle keyboard instruction, and accomplishes the instruction by Keyboard Control;
Data-interface is used for carrying out the exchanges data transmission with external equipment.
Said digital display type fish body biology analyzer is divided into two-layer up and down, and the upper strata is linear measure longimetry unit 1, and it is whole simultaneously as the tray portion of weight weighing unit 2, and lower floor is the miscellaneous part of weight weighing unit 2.
Said linear measure longimetry unit comprises capacitor grid transducer, scale, slip chi 5, pointer 6, and an end of said pointer 6 is fixed in an end of said slip chi 5, and can on the plane perpendicular to slip chi 5, do 180
oRotation.
Said function key 4 comprises length storage key, weight storage key, zero setting key, peeling key, property key, completion key, switch key, clear key.
Said data-interface is a USB interface.
Single-chip microcomputer to sex, the fish body weight of fish, go weight behind the internal organs, fish body body length, height, the thick measurement data of body to encode successively, on LCDs 3, show.Can measure various data successively and be stored to single-chip microcomputer according to showing on the LCDs 3 during measurement, also can select corresponding measurement data to store separately or revise.
Before the weighing fish body, press the zero setting key, realize zero setting, during weighing, set level the fish body, when treating that LCDs 3 weight readings are stablized, press the weight storage key and accomplish the storage of fish body weight; After measuring removal fish body internal organs, set level the fish body, accomplish heavily weighing of ghost, press the weight storage key and accomplish the storage of another time weight; When carrying out weight measurement continuously, after accomplishing a weighing, press the peeling key, carry out weighing again.
When measuring the fish body, with the kiss section of the fish initiating terminal near measuring unit, and make fish head-be parallel to dip stick to the axis of fish tail, it is terminal to move slip chi to caudal peduncle, accomplishes that fish body body is long to be measured, and presses the length storage key and accomplishes storage; Moving hand is accomplished fish body total length and is measured to tail end, presses the storage that the length storage key is accomplished another length data once more; With the fish body plane revolve turn 90 degrees after, make the initiating terminal of the adjacent measuring unit of belly one side, the highest position, moving hand to fish body back is accomplished fish body height and is measured, and presses the length storage key and accomplishes storage; Fish is erected, make fish left side (or right side) only depend on the measuring unit initiating terminal, the thick measurement of fish body body is accomplished in thickness, moving hand to fish body right side (or left side), presses the length storage key and accomplishes storage.
If fish is a milter, then click property key; If raun was then pressed twice property key continuously in 1 second; If can not divide, then not according to.After all determination datas are accomplished,, finish the mensuration work of this fish, get into next record by accomplishing key; Measure wrongly if find a last attribute when measuring, then press switch key, switch to the record that needs change, the short clear key removal record of press, remeasure (weighing) after, completion is stored; If want to delete all records of this fish, then length was pressed clear key 3 seconds, removed all records.
Each button, behind the completion appointed function, indicator lamp is all green by red stain, gets back to redness more rapidly.
All data are pressed the key entry time of accomplishing key in single-chip microcomputer, date of formation, time, numbering, and with machine-readable stored in form.And can directly import other-end (notebook, PDA etc.) through USB interface.
