Embodiment
The schematically illustrated digital tape measure 2 with plastic casing 1 of Fig. 1 to 4.Steel ruler band 3 is arranged on a spring-loaded spinning reel 31.The upper surface of steel ruler band 3 is printed on common dimension mark.These dimension marks can be metric system and/or English system.The locking and unlocking structure 51, printed circuit board (PCB) (PCB) assembly 21, liquid crystal display (LCD) unit 6, battery case 7, bond switching 8 are also set in addition, 9,10, USB (universal serial bus) (USB) data sink 11 and notebook robot calculator or the upper robot calculator 12 of table.
The edge of one of them circular wall 32 of spool 31 offers multiple tiny perforates 33 fifty-fifty, its be positioned at printed circuit board (PCB) 21 every neighbour.Optical sensor comprises that the receiver 22a of a side that is positioned at wall 32 and one are positioned at the light source 22b (will be referred to as hereinafter " optical sensor 22 ") of the opposite side of wall 32.Optical sensor 22 is arranged on printed circuit board (PCB) 21.When chi band 3 extends from housing, spool 31 will rotate, will be along a direction through optical sensor 22 every adjacent perforate 33 and be positioned at wall 32 edges.The movement of perforate 33 will be detected by optical sensor 22.For calculating the minimizing of the diameter that is wound on the chi band on spool in the time that tape measure extends, central processing unit by carry out a kind of algorithm routine convert the digital data signal of being detected by optical sensor 22 to linear dimension, linear dimension and after in liquid crystal display 6 show.
In the time that the pulling action of tape measure stops, spring-loaded latch-up structure 51 will automatically lock tape measure 3.
In the time pressing release-push 5, chi band 3 is retracted the spool being spring loaded 31.The direction along contrary is again passed through optical sensor 22 by perforate 33 on spool wall.This moving direction and distance will be detected by optical sensor 22.Signal will be converted into data again, and be calculated and shown in liquid crystal display 6 by central processing unit.
Bond switching 8 switches the measurement size of demonstration between metric system and English system.
In the time that chi band 3 is retracted completely, the shown size of liquid crystal display 6 should be zero.If there is any residue numerical value to be presented in liquid crystal display 6, as long as press bond switching 9, the shown any numerical value of liquid crystal display 6 will be set to zero.
System of the present invention comprises that a ready-made clothes that is arranged on notebook robot calculator or the upper robot calculator of table detects data recording, analysis and reporting software system.
In the time that ready-made clothes size is measured and be presented at liquid crystal display 6, pressing bond switching 10 will make this size be transferred to the general serial bus receiver 11 that is connected to notebook robot calculator or the upper robot calculator 12 of table by the radio frequency transmitter on printed circuit board (PCB) 21.In normal situation, for example, under SDTP agreement (the digital transceiver protocol of short distance) or SFP agreement (rest frequency to), radio frequency is by 2.4 to 2.4835GHz scope.
On the upper robot calculator 12 of notebook robot calculator or table, a software program is installed.Described program can be carried out in form or other operating system.Described program can independently be used or use in network environment.Described program can be supported different language, and it includes but not limited to English and Chinese.
User can create a user's name and an exclusive password goes to login described program.User can be divided into different groups, with the information of access different aspects from program, to carry out different functions; Also predeterminable detection model and control chart.
User can retrieve default detection model in program.The user who authorizes can create and add new model in program.The user who authorizes can input on model, change and editing data.Program can be by wired or wireless interface from digital measurement mechanism detecting, reception and reading numerical values data.By using digital measurement mechanism, user can obtain and storing measurement data in program.On the display of robot calculator, the position of a visual signal with the reception of reminder-data on model will be shown.A sound signal will be produced to confirm received and storage of data.Data will receive and store by preset order, and user can use computer keyboard or fixed-point apparatus to replace when needed and change described order.
Receiving data can be analyzed.For example: it can with default standard and tolerance level comparison.Exceed tolerance level if receive data, will show a visual signal.Data can for example, in the upper plotting of default control chart (trend map).Completed detection record can be stored, classifies and retrieve (for example: by date, by detection person's identification code, custom IC etc.).The data that receive can be deleted before record is identified and stores.If needed, user can select to utilize computer keyboard on model, to input data, and does not transmit by digital measurement mechanism.The user who authorizes can retrieve, consults, arranges, deletes, copies and print store recording.
Bright a kind of single-point noncontact detecting and the measuring system of providing of this Hair is provided.Chi band is without being provided with coded markings or punching.Wireless Data Transmission can reach the highest convenience and efficiency.Multiple-user network software program allows storage, analysis and the management of testing result.
It being understood that to those skilled in the art that significantly modifications and changes are not regarded as exceeds the scope of the invention.For example, except the form with perforate 33 arranges mark on spool 31, and except the both sides of spool wall 32 arrange optical sensor parts 22a and 22b, also can on the single side of wall, arrange reflection and/or non-reflective typographic(al) mark, and and after two opticses are set on same side.In addition,, except optical devices, the physical unit of convex and/or spill can be equipped with a for example physical switch.Similarly, magnetic means can be set to reach same object.
