Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a length measurement data management system.

(Prior Art) In recent years, advances in semiconductor technology have enabled the miniaturization and high integration of various electronic circuit components, and as a result, such electronic circuit components have come to be incorporated into various products. ing. For example, electronic tape measures have been proposed that have conventionally been used only to measure length, but are equipped with electronic circuit components to add various functions.

As one such electronic tape measure, one having the configuration shown in FIG. 9, for example, has been proposed (Japanese Unexamined Patent Publication No. 182307/1983).

This electronic tape measure converts the amount of movement of a tape-like object 91 that can be freely pulled out from a case opening 94 into the amount of rotation by a measuring roller 92 that rotates as the tape-like object 91 moves. The amount of rotation is pulsed by a rotary encoder 93 connected to the rotating shaft of this measuring roller 92, and the output of this rotary encoder 93 is measured by a counter (not shown). It is configured to calculate the withdrawal amount of.

(Problem to be Solved by the Invention) For example, in a clothing store, when a custom-made customer comes to the store, conventionally a human clerk measures each part of the customer's body, and another clerk writes the measurements. Previously, measurements had to be filled in by hand, but by using the electronic tape measure mentioned above, it becomes possible for a single clerk to do this work, and it also prevents errors in filling in the information. Recently, electronic tape measures have come to be used in industries that require various measurements.

However, at present, the values measured using an electronic tape measure are recorded in the customer ledger, and a more advanced system for managing each customer using a computer has not been developed. Therefore, such a comprehensive customer management system has become an important theme.

The present invention was made in view of the above circumstances, and its purpose is to measure each customer using an electronic tape measure, and to comprehensively analyze the length measurement data for each customer stored in the electronic tape measure using a computer or the like. The object of the present invention is to provide a length measurement data management system that can manage the length measurement data.

(Means for Solving the Problems) In order to solve the above problems, the length measurement data management system of the present invention includes an electronic tape measure that stores length measurement data at multiple locations on an object to be measured; a communication unit that sends out a group of measured length data; a data processing unit that processes the set of measured length data sent out by the communication unit in correspondence with the object to be measured; A storage unit that stores a length measurement data group in a predetermined storage area in correspondence with a corresponding object to be measured, and one of the plurality of length measurement data groups corresponding to the plurality of objects to be measured stored in this storage unit. a display section that reads a group of length measurement data corresponding to one object to be measured by the data processing section, performs appropriate data processing and displays the data; The configuration includes a communication line for sending a length measurement data group corresponding to one object to be measured out of the length measurement data group of Jj failure to another data processing section. The electronic tape measure also includes a rotary encoder whose support shaft is integrally and rotatably fixed to the rotating shaft of a rotating body provided in a case body around which a tape-like object is wound, and an output pulse of the rotary encoder. a first storage unit that stores the converted data by associating the counted number of the counter with the actual amount of the tape-like object pulled out from the case body; an arithmetic unit that calculates the amount of the tape-shaped object to be pulled out from the pulse count counted by the counter based on the conversion data stored in the first storage unit; and a calculation result of the arithmetic unit that stores the calculation result of the arithmetic unit. and a display section that displays the calculation results of the calculation section.

(Function) The electronic tape measure stores length measurement data at multiple locations on the object to be measured, and this length measurement data group is transmitted to the store through an optical transmitter provided on the electronic tape measure and an R3232C communication line, for example. The light is sent to the installed microcomputer through an optical receiver provided in an interface box connected to the installed microcomputer. and,
The data processing unit, which is a component within the microcomputer, processes the length measurement data group sent from the electronic tape measure in correspondence with the object to be measured, and also processes this processed data corresponding to the length measurement data group. The information is stored in a predetermined storage area of the storage unit in a form that corresponds to the object to be measured. Furthermore, the microcomputer is equipped with a display unit such as a CRT, and the microcomputer also includes a length measurement data group corresponding to one measured object among a plurality of length measurement data groups corresponding to a plurality of measured objects stored in the storage unit. The data processing unit reads out the data, performs appropriate data processing, and displays the data on the display unit. In other words, in terms of display methods, only numerical values are displayed in a list corresponding to the name of the measurement point (for example, shoulder width, sleeve length, etc.), or the shape of the garment is displayed based on the length measurement data. It is possible to display the information graphically so that it can be confirmed visually. In addition, the length measurement data displayed on the display unit can be transferred via a communication line to a data processing unit in a computer installed in a sewing factory, for example, and can be immediately turned into a product at that sewing factory. The structure is as follows.

Further, the electronic tape measure has a support shaft of a rotary encoder integrally and rotatably fixed to the rotating shaft of a rotating body around which a tape-like object is wound, and is equipped with a counter that counts output pulses of the rotary encoder. The first storage section stores conversion data for converting the pulse count number into the amount of withdrawal by associating the count number of the counter with the actual amount of withdrawal of the tape-like object from the case body. Since the rotary encoder is fixed to the rotating shaft of the rotating body, it is possible to accurately detect the rotational state of the rotating body, and detection errors do not occur. In addition, the outer diameter of a tape-shaped object wrapped around a rotating body is different from the outer diameter when it is completely wrapped around the rotating body and when it is pulled out to a certain extent, and the change in diameter is also not linear. Since it is curved, it is difficult to express the change mathematically, and even if it were expressed by an approximate expression, an error would occur in the amount of tape-shaped object pulled out by that expression. Therefore, in the electronic tape measure according to the present invention, the relationship between the count number of the counter and the actual amount of the tape-like object pulled out from the case body is determined in advance, and the pulse count number is converted into the amount of withdrawal from the relationship. It is stored as conversion data for When the tape-shaped object is pulled out from the case body, the amount of the tape-shaped object pulled out is determined from the pulse count counted by the counter based on the conversion data stored in the first storage section, and the value is calculated. The information is stored in the second storage section and digitally displayed on the display section. This allows accurate length measurement at all times. Note that the second storage unit is configured to be able to store a plurality of types of length measurement values.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the electrical configuration of the length measurement data management system of the present invention.

In the figure, the output of an electronic tape measure 51 in which length measurement data of each part of the object to be measured is stored is led to a transmitter 52 that converts the length measurement data into an optical signal and sends it out.
An optical signal indicating the length measurement data sent from the optical sensor 2 is received by a receiving section 53 capable of receiving the optical signal. That is, in the digital optical communication performed between the transmitter 52 and the receiver 53, the transmitter 52 includes a high-output infrared LED, and the receiver (interface box) 53 includes a high-sensitivity photodiode. is configured. Further, the output of the receiving section 53 is guided to a data processing section 54, which constitutes a CPU and is surrounded by a broken line. The data processing unit 54 is supplied with the output of an input unit 55 consisting of a keyboard with a numeric keypad, etc., and also stores the derived length measurement data in a predetermined storage area in correspondence with the corresponding object to be measured. The sections 56 are bidirectionally connected. When length measurement data is input from the reception section 53 to the data processing section 54, the input section 55 inputs a code unique to the object to be measured corresponding to the length measurement data. The code specific to the object to be measured from the input section 55 and the length measurement data from the receiving section 53 are stored in a predetermined storage area of the storage section 56 in correspondence with each other.

Further, the output of the data processing section 54 is guided to a display section 57 and also to a data processing section 58 of a computer installed at another location via a communication line 62. In the read mode, when a code unique to an arbitrary object to be measured is input from the input section 55, the display section 57 reads out the length measurement data corresponding to the code from the storage section 56 and displays it. The display format at that time is
For example, if you are a clothing store, you may want to display only numerical values in a list corresponding to the name of the measurement point (for example, shoulder width, sleeve length, etc.), or you can see what kind of shape the garment will be based on the length measurement data. It is possible to display the information graphically so that it can be confirmed visually.

FIG. 2(a) and (bl) show the schematic structure of the electronic tape measure 51.

In the same figure, a rotating body 3 around which a tape-shaped object 2 made of fiber, for example, is wound is built into the case body 1, and one end of the rotating shaft 3a of this rotating body 3 is attached to the case body 1. It is rotatably supported by being inserted into a support hole 1b formed in one side wall 1a. In addition, the rotating shaft 3a
An insertion hole 3b is formed along the axial direction of the rotary encoder 4, and the support shaft 4a of the rotary encoder 4 is inserted through the inner wall 1c of the case body 1 and inserted from the other end of the rotary shaft 3a. It is inserted into hole 3b. The support shaft 4a is fixed so as to rotate integrally with the rotation shaft 3a. Further, one end (inner end of the spiral) of a spring body 6 formed in a spiral shape is fixed to the rotating shaft 3a, and the other end (outer end of the spiral) of the spring body 6 is fixed to the inner wall. It is fixed to a locking protrusion 1d protrudingly provided at a proper position of 1c. Further, an annular tape-shaped object winding frame (hereinafter simply referred to as a winding frame) 7 is formed in an example part of the rotating body 3 so as to enclose the spring body 6, and this winding frame The proximal end portion is attached to 7 and the tape-like object 2 is wrapped around it. The tape-like object 2 is always biased by the action of the spring body 6 so that it is completely wound up on the winding frame 7.

The tip of the tape-like object 2 is pulled out from the drawer 01e of the case body 1, and the locking fitting 8 attached to the tip restricts the tape-like object 2 from being pulled into the case body 1 by the biasing force of the spring body 6. It looks like this. In addition, the other side wall 1f of the case body 1 has an opening 1 through which light can pass.
A transmitting section 52 for transmitting an optical signal is provided inside the case main body l in opposition to this opening 1g.

FIG. 3 shows the electrical configuration of an electronic tape measure 51 according to the present invention.

In the figure, the rotary encoder 4 sends out two types of signals, the A-phase signal and the B-phase signal shown in FIG. It is introduced into the CPU 12 via a certain interface. The CPU 12
The CPU 12 is bidirectionally connected to a ROM 13 that stores 12 operating programs and conversion data to be described later.
R for counting to store data necessary for calculation processing in
It is bidirectionally connected to the AM 14 and the data storage RAM 15 that stores the calculation results of the CPU 12, respectively.

Further, the output of the CPU 12 is guided via an interface 16 to a data display section 17 and a printer 18 for outputting the data, and also to a transmitting section 52 that converts it into an optical signal and sends it out. Further, the output of the memory switch 19 for storing the calculation result of the CPUI 2 in the data storage RAM 15 and the output of the power supply switch 20 that supplies power to each part of the microcomputer 10 are connected to the CPUI via the interface 16. It is given to 2.

FIG. 4 shows two types of output waveforms from the rotary encoder 4. Here, the same figure (al, (bl) shows the re-output relationship of the low re-encoder 4 when the tape-like object 2 is pulled out from the case body 1, the same figure fc),
(d) shows the tape-like object 2 pulled out from the case body 1.
The relationship between the re-output of the rotary encoder 4 in the case of winding inward is shown.

Based on these signals, the CPU 12 determines whether the tape-like object 2 is being pulled out from the case body 1 or drawn into the case body 1. In other words, as shown in FIG. 4(al), (b), if the B-phase signal is at the rLJ level when the A-phase signal rises, and the B-phase signal is at the rHJ level when the A-phase signal falls, then the tape It is determined that the shaped object 2 is being pulled out from the case body 1, and in this case, when the A-phase signal rises and falls, the counting RAM is
Add 1 to the contents of 14. In addition, as shown in Fig. 4 (C1, (di), when the A-phase signal rises, the B-phase signal goes to rH.
J level, and if the B-phase signal is at rLJ level when the A-phase signal falls, it is determined that the tape-shaped object 2 is being drawn into the case body 1, and in this case, the A-phase signal is at the rLJ level. The contents of the counting RAM 14 are decremented by 1 when the phase signal rises and falls, respectively.

Furthermore, in addition to storing the operating program of the CPU 2, the ROM 13 also stores the conversion data described above. This conversion data is data showing the relationship between the number of output pulses of the rotary encoder 4 and the amount of the tape-shaped object 2 pulled out from inside the case body 1, and is a change curve shown in FIG. That is, the tape-like object 2 wound around the rotating body 3 has an outer diameter L0 when the entire tape-like object 2 is wound around the winding frame 7 of the rotating body 3;
The outer diameter L4 (i is an arbitrary integer) when pulled out to a certain extent is different, and the change in diameter (in this case, the change in diameter from Lo to Lo) is a straight line as shown in Figure 5. Since it is difficult to express the change mathematically, the number of output pulses of the low-return encoder 4 (the number of counts stored in the counting RAM 14) and the actual output from the case body 1 of the tape-shaped object 2 are The relationship with the withdrawal amount is determined in advance as an actual value, and the relationship is stored as conversion data. An example of this conversion data is shown in the table of FIG. That is, when the count value is 10, the withdrawal amount is 1 (em), when the count value is 20, the withdrawal amount is 2 (cll), when the count value is 35, the withdrawal amount is 3 (elm), and the count value is 57. Withdrawal amount is 4
(ell) etc.

If this count value (output pulse number) is plotted on the horizontal axis and the extraction amount (length) is plotted on the vertical axis, a curved graph shown in FIG. 5 is obtained.

In this case, if the withdrawal amount of the tape-like object 2 is displayed in 1 unit, when the count value is 14, the withdrawal amount is displayed as 1 (am), and when the count value is 15, the withdrawal amount is displayed as 1 (am). is configured so that it is displayed as 2 (cm). In other words, the count value in the middle between the count value Xn-1 corresponding to an arbitrary withdrawal amount (am) and the count value Xn corresponding to the next withdrawal amount (C11), (X11-1 10Xn) / 2, is 1. This value is used as a criterion for changing the display. However, 0.
When displaying in units of 5C11, one display is further determined based on half of the value.

Next, the operation of the electronic tape measure 51 having the above configuration will be explained with reference to the flowcharts of FIGS. 7 and 8.

When using this electronic tape measure 51, first turn on the power switch 20 to supply power to each part. At this time, the display on the data display section 17 is cleared to 0 or 0.0, and the count RAM 14 is also cleared to O.

In this state, the locking fitting 8 that was locked to the outlet 1e of the case body 1 is pressed against the object to be measured, and the zero scale position of the tape-shaped object 2 is made to match the measurement reference position of the object to be measured. The tape-shaped object 2 is pulled out to the other end position of the object to be measured. At this time, the two types of output from the rotary encoder 4 are as shown in FIGS. 4(a) and 4(b): the B-phase signal becomes rLJ level at the rise of the human phase signal (step Sll, 512), and Since the B-phase signal becomes rE (J level) when the A-phase signal falls (step S21. 522), the tape-shaped object 2 is pulled out from the case body 1 in the CPU 12 to which such a signal is input. In this case, each time the A-phase signal rises, the count value of the counting RAM 14 is incremented by 1 (step 313), and each time the A-phase signal falls, the count value of the counting RAM 14 is incremented by 1.
The count value of AM14 is incremented by 1 (step 523).

Thereafter, the tape-shaped object 2 is pulled out to the other end of the object to be measured, and when the length measurement is completed, the memory switch 19 is turned on (specifically, the memory switch 19 is turned on twice in a row in one second). operation), the CPU 12 reads out the count value stored in the count RAM 14 at that time, reads out the conversion data from the ROM 13, and stores the amount of conversion data corresponding to the count value as a length measurement value. The data is stored in a predetermined storage area of the storage RAM 15. In addition, this length measurement data is
6 on the data display section 17, and can be printed out on the printer 18 by turning on a printout switch (not shown).

Thereafter, the tape-shaped object 2 that has been pulled out is pulled into the case body 1 by the biasing force of the spring body 6.

At this time, the two types of output from the rotary encoder 4 are as shown in FIG. Since the B-phase signal becomes the "L" level when the signal falls (Jl) (step S
2L 522), CP to which such a signal is input
In the UI 2, it is determined that the tape-like object 2 is being drawn into the case body 1.

In this case, the count value of the count RAM 14 is decremented by 1 each time the A-phase signal rises (step 514), and the count value of the count RAM 14 is decremented by 1 each time the A-phase signal falls (step 514). 524)
. As a result, when the tape-like object 2 is completely drawn into the case body 1, the count value in the counting RAM 14 is O.

By repeating the above operations, all the necessary measurement points of the object to be measured are measured, and all the measurement results are stored in the data storage RAM 15. The data storage RAM 15 can store, for example, 16 or 32 pieces of such data (however, the number is not limited to this number).

In this way, when the length measurement of one object to be measured is completed,
The opening 1g formed on the other side surface 1f of the case body 1 of the electronic tape measure 51 is opposed to the receiving section 53 constituting the interface box, and the transfer switch (not shown) provided on the electronic tape measure 51 is turned on. By doing so, the length measurement data stored in the data storage RAM 15 is sent to the receiving section 53 by digital optical communication, and the data processing section 54
Enter within. At this time, the CPU is in the write mode, and by inputting a code specific to the object to be measured corresponding to the derived length measurement data from the input section 55, the memory section 56 stores the code corresponding to the code. The length measurement data input from the receiving section is stored in a predetermined storage area. By performing such an operation for each object to be measured, length measurement data corresponding to each object to be measured is sequentially stored in the storage section 56.

When reading the data stored in the storage section 56 in this manner, the CPU is set to the read mode, and the code of the object to be read is inputted from the input section 55. Thereby, the data processing section 54 reads the length measurement data of the corresponding code from the storage section 56, and displays the read length measurement data on the display section 57 as necessary. That is, as mentioned above, the display format at that time is
For example, in a clothing store, the object to be measured is the customer, so it may be possible to display only the measurements of the customer's shoulder width, sleeve length, etc. in a list, or to display various measurements based on the measurement data. It is designed to display a graphic so that you can visually check whether the garment will fit the shape.

Furthermore, since the length measurement data read from the storage section 56 can be sent to the data processing section 58 of a computer installed at another location via the communication line 62, this data processing section 58 can be installed in a sewing factory, for example. By doing so, it is possible to immediately equip the customer's clothes based on the given length measurement data, which has the advantage of shortening the time from order to delivery.

In the above embodiments, the communication method between the transmitting section and the receiving section is described as digital optical communication, but other communication methods such as ultrasonic waves, magnetic waves, etc. are also possible. Further, in the above embodiment, the CPU 12 directly counts the output pulses of the rotary encoder 4 of the electronic tape measure 51 and uses the counting RA.
The count value in M14 is configured to be a count amplifier or count down, but the rotary encoder 4
It is possible to configure the microcomputer 10 to count the output pulses by an external counter and transfer the count results to the counting RAM 14 in the microcomputer 10. Further, although a fiber tape is used as the tape-like object 2, it is also possible to use a resin tape, a metal tape, or the like.

(Effects of the Invention) The length and decline data management system of the present invention is capable of introducing the length measurement data measured by an electronic tape measure and stored into the data processing unit via the communication unit, and processing the data as appropriate in the data processing unit. Therefore, the length measurement data can be stored in the storage section in correspondence with the code unique to the object to be measured, and can also be read out and sent to the display section or other data processing section as needed. Since the length measurement data for each measurement object is stored in the storage section, it is possible to comprehensively manage the length measurement data of a plurality of objects to be measured.
