Description

  The present invention relates to a measuring apparatus used for measuring, recording and managing physical quantities such as the temperature of articles.

  In a distribution system that delivers chilled foods, fresh foods, frozen foods, dairy products, etc. from warehouses to stores and customers, products are managed to manage quality and hygiene until they are delivered to customers. It is desired to be placed under proper temperature control.

  Therefore, it is desired that a carrier such as a truck driver measures and manages the temperature of each commodity being transported at an appropriate timing during distribution including acceptance and delivery. Japanese Patent Application Laid-Open No. 2000-76504 discloses a time stamp with a temperature measurement function for managing the temperature of goods in the distribution process from the time of shipment and receipt to the storage of goods. This time stamp includes a non-contact measuring means (non-contact thermometer) that measures the surface temperature of the object in a non-contact manner, a temperature recording means that records the measured temperature and its measurement time together, and the surface temperature and the measurement time. With the printing means for printing, temperature control and hygiene management in the distribution process can be thoroughly performed with a single device (time stamp).

  In the distribution process, time information alone is not enough to perform temperature management of products with higher accuracy, and information that identifies each item for which temperature management is being performed, such as items and serial numbers, is recorded. It is desirable. The identification information of the measurement object can be manually input at the time of measurement with reference to a product label or a tag. Alternatively, if there is a list created in advance, it is also possible to input it by referring to it. However, it takes time to input identification information, and an input error may occur. Even if identification information is input while referring to the list, there is no guarantee that the temperature of the product is actually measured.

  A non-contact type thermometer is convenient because it can be measured away from the product. However, if identification information is acquired from a label or a slip attached to the product, it is necessary to approach the product. Further, while the temperature can be measured away from the product, it is not possible to specify which product's temperature has been measured only with the time information.

  Therefore, in the present invention, there is provided a measuring device for measuring the temperature or the like that can easily measure the temperature of a measurement object such as a product or other physical quantity, and can reliably record which product has been measured. The purpose is to do.

  In the present invention, a detection unit that measures a physical quantity such as temperature is acquired while having a physical relationship in which a distance such as contact, immersion, insertion, or connection of a sensing unit with a measurement object is limited, and wireless information is acquired. By making the wireless unit of the non-contact type movable as a unit, and limiting or narrowing the receivable range of the wireless unit to the same extent as the measurement distance of the temperature detection unit, the physical quantity and identification information of the measurement object are simultaneously and The information is acquired without being confused with information on other measurement objects. Further, these pieces of information are output in association with each other so that they can be recorded on a built-in recording medium or an external recording device. In other words, the measuring device of the present invention has a detection unit that measures the physical quantity of the measurement object in a state in which the distance to the measurement object is limited, and moves together with the detection unit to detect A wireless unit whose range is about the measurement distance of the unit is the range or limit for receiving the identification information wirelessly output from the transmission source, and the measurement value of the detection unit is output in association with the identification information obtained by the wireless unit. Output unit.

  In this specification, one of the physical relationships in which the distance to the measurement object is limited is that the sensor itself or a sensing unit that is a part of the sensor is in contact with the measurement object and senses a physical quantity. This includes a state in which the portion to be touched on the surface of the object to be measured, dipped in, or inserted into the object. In this specification, the sensor mainly indicates a portion for detecting a physical quantity. Furthermore, in the case of measuring physical quantities such as radiation and current, the state in which the sensor is brought close to the radiation source or wiring is also included in the physical relationship in which the distance from the measurement object is limited. Therefore, the measurement apparatus of the present invention includes a sensor that is brought into contact with or close to the measurement object, a detection unit that is physically connected to the sensor and that measures a physical quantity of the measurement object based on a signal from the sensor, and the sensor and the detection unit. And a unit that receives the identification information wirelessly output from the transmission source, and an output unit that outputs the measurement value of the detection unit in association with the identification information obtained by the wireless unit. And have.

The measuring device has a rod having a sensor at the tip as means for maintaining or limiting the distance between the sensor and the detection unit. With only the wiring connecting the sensor and the detection unit, it is necessary for the user to hold the sensor with his hand to make contact with or close to the measurement object. If the sensor and the detection unit are connected with a rod, the position of the sensor can be remotely controlled. Furthermore, the measuring device, the measured value of the detection unit, and a display panel for displaying a plurality of identification information obtained to the wireless unit from the plurality of sources at a distance of about the length of the rod, displayed on the display panel The output unit has a function of selecting desired identification information from the plurality of identification information and a recording switch. When the recording switch is operated, the output unit is displayed on the display panel at the timing when the recording switch is operated. The identification value selected by the measurement value of the detection unit and the function to be selected is output in association with each other.

  One of the most useful contact type detection units is a temperature detection unit that contacts a measurement object and measures its temperature. In the case of a measuring apparatus including a rod having a sensor at the tip, it is desirable that the wireless unit can set a distance about the length of the rod as a receivable range. The output destination of the output unit is a recording medium such as a built-in or detachable RAM or disk, and an external recording device such as a personal computer or a server. In particular, if the output unit has a wireless interface, data can be output to the outside via radio waves or light. If the output unit has a built-in wireless LAN interface, the temperature measurement device directly passes through the Internet. Thus, data can be output to a storage medium such as a server. It is also possible to output data by e-mail.

  In the recording method of the present invention, the physical quantity such as the temperature of the measurement object is measured by a detection unit that measures the physical quantity of the measurement object in a state in which the distance to the measurement object is limited. At the same time, an acquisition step of acquiring identification information by a wireless unit in which the range of about the measurement distance of the detection unit is a range that can be received wirelessly from the transmission source, and the measurement value and the identification information are output in association with each other. An output step. The detection range (receivable range) of a wireless unit is an area where information from a transmission source within that range can be acquired and information from a transmission source outside the range cannot be acquired. It is not necessary to determine, and information from a transmission source located at a position that is twice or several times away from the detection range cannot be acquired, and information from a transmission source in the vicinity of the detection range may be acquired.

  In a detection unit in which a physical quantity cannot be detected unless the sensor has a physical relationship with the measurement object, such as touching, gripping, or inserting the sensor, the measurement object is uniquely determined. When detecting physical quantities such as temperature, humidity, illuminance, concentration, current, voltage, etc. for each measurement object in scenes such as distribution processes, periodic inspections, and patrol inspections, the physical unit between the detection unit and the measurement object In order to generate a general relationship, the distance between the detection unit and the measurement object, that is, the measurement distance is determined or limited. In the case of a contact-type temperature detection unit, the temperature detection unit itself is brought into contact with the measurement object, or the physical quantity is measured at a position separated from the rod object by contacting the tip of the rod with the measurement object. The rod for temperature measurement has a built-in or attached suitable temperature sensor such as a thermocouple or thermistor at the tip. Therefore, the measurement distance between the temperature detection unit and the measurement object is about several centimeters to several tens of centimeters, which is sufficiently smaller than the size of most measurement objects. Therefore, if the measurement distance is the detection distance, the wireless unit does not confuse and acquire information from the transmission source of the measurement object and information from the transmission source of the adjacent measurement object.

  For this reason, the detection unit and the wireless unit are moved together, and the physical quantity is measured by acquiring both the physical quantity and identification information of the measurement object at the same time or when the detection unit is in a state of measuring the physical quantity. The identification information of the measured object can be acquired easily and reliably. For this reason, by associating the measurement value with the identification information, the measured object to be measured can be uniquely defined, and the measurement can be recorded without fail.

  It is desirable that the measurement object has a built-in non-contact transmission source with a small wireless output or is attached to the surface. In recent years, a proximity type IC tag that outputs identification information wirelessly, particularly with radio waves ( Wireless tags, IC chips, etc.) can be used. IC tags are considered to be compact and low-cost, and more disposable. For this reason, when packing, it can put in a measuring object, or can be affixed on the surface of a measuring object with a product label or a slip. If you adjust the wireless output of the IC tag and the sensitivity of the wireless unit, or if the wireless output of the IC tag cannot be adjusted, set the sensitivity of the wireless unit so that an appropriate receivable range is obtained. At the same time as measuring a physical quantity such as temperature while touching, only the identification information of the object to be measured can be acquired in a limited manner by radio, and these can be correlated.

  Furthermore, it has a time measuring unit, and an output unit can record them by associating and outputting the measurement time and the identification information. Therefore, it is possible to easily record and manage the measurement object temperature accurately and accurately including the progress. The clocking unit can also use the CPU clock.

  If the size of the measurement object is small, the wireless unit may receive a plurality of pieces of identification information. However, even in such a case, since the receivable range of the identification information is narrow, a large number of identification information is not read so as to confuse the user, and an appropriate one is selected from several pieces of identification information and recorded together with the measured value. Can do. It is also possible to provide a selection switch so as to cope with a situation where a plurality of pieces of identification information can be selected. Furthermore, when there are multiple choices of identification information, a distance for measuring physical quantities, such as providing a sensitivity adjustment circuit that reduces the sensitivity of the wireless unit until it is reduced to one, or adjusting the length of the rod By providing means that can adjust the information, it is possible to save the user from selecting identification information.

  Furthermore, when the user recognizes that the measurement value and identification information of the measurement object whose physical quantity is being measured are obtained, the measurement value and identification information are output from the output unit so that the measurement value and identification information can be output in association with each other. It is effective to provide a recording switch for instructing the timing for outputting information. With one push, you can easily and reliably record the items, measurement values and identification information necessary for temperature management, etc., and also record the values when the temperature being measured is stable as measurement values This recording switch is available. These data can be acquired by one push and sent to an external recording device via a wireless interface of the output unit.

  By using the temperature measuring device of the present invention, if a proximity type wireless tag having identification information is attached and shipped to an object to be transported in advance, the temperature measuring device of the present invention can be used to control the temperature of the object in circulation. The measurement value of the measurement object and the identification information can be associated and recorded simply by measuring. Therefore, the temperature of each product (article) can be accurately and easily managed in all the processes from when the measurement object is shipped to when it is received, transported, and delivered to the user by the distributor. You can leave the history.

Fig.1 (a) and FIG.1 (b) show the example which uses the temperature measuring apparatus of this invention in a distribution | circulation process. FIG. 2 is a perspective view showing an overview of the temperature measuring device. FIG. 3 is a block diagram showing a schematic configuration of the temperature measuring device. FIG. 4 is a flowchart showing the operation of measuring and recording the temperature in the temperature measuring device.

  Embodiments of the present invention will be further described below with reference to the drawings. FIG. 1 shows a state in which the temperature in an article distribution process is managed using a temperature measuring device 10 according to the present invention. An IC tag 70 having identification information φ2 for identifying each object is attached to each object (package or container) 80 shipped from a manufacturing factory or the like. An IC tag is called a wireless tag or RFID (Radio Frequency IDentification) tag, and consists of an IC chip and an antenna attached to an object. Various shapes such as "label type", "card type", and "stick type" There are things. Therefore, the IC tag 70 may be attached to the surface of the object 80 together with a label as shown in the figure, or may be placed inside the object 80.

  The data in the IC chip of the IC tag 70 can be accessed in a non-contact manner by external radio waves. The IC tag, which is a non-contact type information output device, can include identification information φ2 including a product code that has been marked by using a bar code or a label, a manufacturing number unique to the individual, It can be read without contact. Further, unlike the barcode, the IC tag 70 can be read in any direction as long as the radio wave reaches, so that the identification information φ2 can be read even if the IC tag 70 is not visually visible. On the contrary, the identification information φ2 cannot be acquired unless it is within the reach of the radio wave, and the reach of the radio wave is determined by the output of the IC tag 70 and the sensitivity of the wireless unit that receives the output radio wave. .

  FIG. 2 is a perspective view showing an outline of the temperature measuring device 10. FIG. 3 is a block diagram showing a schematic configuration of the temperature measuring device 10. The temperature measuring device 10 of this example is a small handy type and has a substantially rectangular housing 11. A rod 12 having a length of about 10 cm and a thin stainless steel tip 12 a is attached to the end 11 a of the housing 11. A temperature sensor 21, for example, a thermocouple is attached to the tip 12 a of the rod 12, and the temperature of the object 80 can be measured by bringing the tip 12 a into contact with the object 80. The rod 12 may have a constant length, or may include a slide mechanism or the like that can adjust the length. An LCD 13 serving as a display panel is installed on the upper surface 11b of the housing 11, and displays a measured value φ1 converted from a value detected by the temperature sensor 21 to a temperature, received identification information φ2, and the like. In addition, a recording switch 14, a power switch 15, and the like are disposed on the operation unit 16 on the upper surface 11 b of the housing 11.

  As shown in FIG. 3, the measuring device 10 converts the data obtained by the sensor 21 attached to the tip 12a of the rod 12 into a temperature measurement value φ1, and obtains it as a temperature measurement value. 20 and a wireless unit 30 for receiving the identification information φ2 transmitted from the IC tag 70 by radio. The wireless unit 30 includes an antenna 31 that receives a radio wave from the IC tag 70, a transmission / reception unit 32 that acquires information from the radio wave by the antenna 31, and an ID reader 33 that decodes the identification information φ2 from the information obtained by the transmission / reception unit 32. And. The transmission / reception unit 32 can adjust sensitivity, and can set a range in which information from the IC tag 70 that is a transmission source can be received (receivable limit). In this example, a receivable range is set so that information is acquired from the IC tag 70 in the range of the length of the rod 12 and information is not acquired from the IC tag 70 in a longer distance.

  When the IC tag 70 is incorporated in the label 75 of the object 80 and the objects 80 are stacked so that the labels of the different objects 80 are in contact with each other, the plurality of IC tags 70 that are transmission sources are the same. May exist at a distance. In that case, information from the plurality of IC tags 70 cannot be separated by setting the receivable range of the wireless unit. Therefore, the ID reader 33 displays a plurality of pieces of identification information on the LCD 13 and the user is required to select an operation from among them. If the measurement apparatus 10 cannot separate the pieces of identification information, the ID reader 33 displays them on the LCD 13. A function to be selected by the user is provided. However, in many cases, the label 75 including the IC tag 70 is stacked so as to be visible from the outside so that the loaded object 80 can be confirmed from the outside. Therefore, the plurality of IC tags 70 are unlikely to face each other, and there are few cases where identification information cannot be selected. Furthermore, it is not difficult to stack the labels 75 so that they do not face each other, and this problem can be solved by adopting an appropriate stacking method.

  When the IC tag 70 is placed in the object 80, it can be obtained from the plurality of objects 80 as long as the characteristic length of the object 80 is several times the length of the rod 12. The identification information can be differentiated sufficiently. While the length of the rod 12 is about 10 cm, the length of one side of many objects to be transported as luggage is several tens of cm or more, and the information from the built-in IC tag 70 is sufficiently divided into individual pieces. Can be identified. Further, as can be seen from this, the receivable range of the transmission / reception unit 32 does not have to be clearly or digitally the same as the length of the rod 12, and is several tens of centimeters which is a characteristic length of the object 80 or A range close to the length of the rod 12 with respect to 1 m may be used.

  Further, the wireless unit 30 of this example has not only a function as a receiving unit but also a function of writing information to the IC tag 70 of the object 80. Therefore, it is possible to write the content measured by the measuring device 10 on the IC tag 70 and use the IC tag 70 as a recording medium, and it is possible to store the entire history of the package 80 in the IC tag 70. It is. When the IC tag 70 does not have such a large storage capacity, the identification information φ9 of the measuring device 10 set in the measuring device 10 is written in the IC tag 70, and information on the workers involved in the distribution of the product 80 is distributed in the distribution process. It is possible to leave.

  The measuring apparatus 10 includes a CPU 40 that controls all of its functions. One function realized by the CPU 40 is a function as an output unit that associates and outputs the measured value φ1 output from the temperature detection unit 20 and the identification information φ2 obtained by the wireless unit 30. Therefore, the CPU 40 associates the measured value φ1 output from the temperature detection unit 20 when the recording switch 14 is operated with the identification information φ2 obtained from the wireless unit 30 and outputs the correlation to the data recording memory 51. Then, the measured value φ1 and the identification information φ2 are recorded using the memory 51 as a history file. The output destination of the measured value φ1 and the identification information φ2 is not limited to the built-in memory 51 such as RAM or ROM, and can be written and recorded in the IC tag 70 as described above. The external communication interface 48 can output and record the measured value φ1 and the identification information φ2 to a personal computer or a server on the Internet using communication means such as wireless or LAN.

  The measuring apparatus 10 further includes a time measuring unit (RTC) 45. For this reason, the CPU 40 also outputs time information φ3 obtained from the timing unit 45 in association with the measured value φ1 and the identification information φ2. The time information counted by the CPU 40 may be associated and recorded instead of the time information φ3. In any case, by adding the time information φ3, the time when the measured value φ1 was obtained is clarified, and the data at which point in the distribution process is clarified. For this reason, the temperature management information of the article 80 at each stage of the distribution process can be automatically generated and recorded.

  The measuring apparatus 10 includes a ROM 52 in which a program of the CPU 40 is recorded. The ROM 52 also stores identification information φ9 of the measuring apparatus 10. The identification information φ9 can be information that directly or indirectly identifies a staff member, a driver, or the like who operates the measuring apparatus 10. Therefore, as described above, the information on the staff involved in each stage of the distribution process can be recorded in the IC tag 70. Further, as information output from the measuring device 10, it is possible to add the identification information φ9 of the measuring device 10 to the measured value φ1, the identification information φ2 of the baggage 80, and the time information φ3. Makes it easier to manage.

  The temperature measuring apparatus 10 of this example includes a function such as a serial interface such as a USB, a LAN interface, a wireless interface, or a wireless LAN interface, or an interface external communication interface 48 having a plurality of these functions. Controlled to function as an output unit. Therefore, it communicates with an external information processing apparatus such as a server or a host computer 59 via the Internet or the like, and outputs information obtained from the object 80 on time, for example, when the recording switch 14 is pushed once. Or information stored in the recording unit 51 of the measuring apparatus 10 can be output. For this reason, on the side of the external terminal 59 such as a personal computer, the data recorded and accumulated in the delivery process is downloaded, and based on that data, a list of management data including temperature, product name, and measurement time is prepared. Easy to create.

  In the temperature measurement device 10 of this example having the contact-type temperature detection unit 20 and the non-contact-type ID reader (wireless unit) 30, the detection range of the ID reader 30 is set as the contact of the contact-type temperature detection unit 20. By setting the distance, that is, the length of the rod 12, the identification information φ <b> 2 of the temperature measurement object 80 can be obtained at the same time by one action of measuring the temperature. And if the contact distance of the contact-type temperature detection unit 20 is small enough to distinguish the wireless unit 30 when compared with the size of the object 80, it is configured to move together with the temperature detection unit 20. Thus, the identification information φ2 of the target object 80 can be obtained separately from the information of the other target object 80 only by the operation of measuring the temperature of the target object 80 even under the condition where a plurality of target objects 80 are loaded. Can do. For this reason, the measured value φ1 can be recorded in one push together with the identification information φ2 of the object 80 obtained. Therefore, the temperature measuring device 10 of the present invention can be used at various stages of the distribution process.

  Returning to FIG. 1 (a), at the factory or package collection site 99 of the package 80, the worker 91 who has received the package 80 for shipment uses the measuring device 10 as shown in FIG. 1 (b). By measuring the temperature of each package 80, the package 80 to be shipped can be confirmed by the identification information φ2. At the same time, the shipment status of each package can be recorded by associating and recording the temperature φ1 of each package and the identification information φ2 of the package 80.

  In the middle of being transported by the truck 96, when the driver 91 loads the truck 80 on the truck 96, the temperature of the plurality of luggage 80 is set using the measuring device 10 at an appropriate timing such as during transportation. By measuring, the measured temperature φ1 of each load 80 and the identification information φ2 of each load 80 can be recorded together with the time information φ3.

  Further, at the delivery destination (delivery destination) 98 that receives the parcel 80, the worker (user) 91 who has received the parcel 80 measures the temperature of each parcel 80 by the measuring device 10 as shown in FIG. Thus, while confirming and recording each package received by the identification information φ2, the state when each package 80 is received can be recorded by the temperature measurement value.

  FIG. 4 is a flowchart showing the temperature measurement operation of the temperature measurement apparatus 10 of this example. In this measuring apparatus 10, a process of constantly measuring the temperature φ1 by the contact-type temperature detection unit 20 (step 61), and a process of acquiring the identification information φ2 by the non-contact type radio unit 30 before, after or simultaneously (step 61). Step 62) is performed together. The data acquired in this acquisition step (step 60) is displayed on the LCD 13, and if the displayed data is desired, the data is selected by pressing the recording switch 14 in step 63. Further, in step 64, the data φ1 and φ2 are associated with each other, and are output as one record and recorded in the memory 51, for example. If a plurality of pieces of identification information φ2 are displayed, the measuring device 10 is moved to select a position where one piece of identification information φ2 is displayed, or the package 80 is selected from the plurality of pieces of identification information φ2 displayed. Appropriate identification information φ2 may be selected by looking at the label or the like.

  As described above, the temperature measuring apparatus 10 of this example can obtain identification information only by measuring the temperature with a contact-type thermometer. There is no need to check and write identification information. Therefore, the user can easily record the package identification information and the measurement value in association with each other. For this reason, in any scene of the distribution process, the operator can obtain the identification information simply by measuring the temperature, and then distribute the measurement temperature and identification information at that time, and also add the time information. Data can be created to manage the status of packages or goods. For this reason, there is no need to read the label attached to the package directly and write the information. Therefore, it is possible to acquire highly accurate information without taking time and effort, improve the quality control capability, and improve the service to customers.

  The temperature measuring device according to the present invention may be any device as long as the temperature detection unit and the wireless unit can move together, and need not include the memory and other mechanisms. However, if they are portable and can be moved together, they are easy to use and can be integrated at a low cost.

  Moreover, the temperature measuring device according to the present invention can be used not only for measuring the temperature of an article in the distribution process but also for all uses or processes where temperature management is required or desirable. In particular, IC tags suitable as means for outputting identification information have recently been reduced in size and cost, can be attached to various places or products, and can be disposable. Therefore, there are a wide variety of applications in which the temperature measuring device according to the present invention can be used in combination with an IC tag. For example, in the case of cooking food, it is not only used to monitor the storage state of frozen or refrigerated foods, but it also measures the temperature of food after cooking and obtains it from an IC tag attached to a package. By recording it together with the identification information, it can be used for preventing the occurrence of food poisoning or for investigating the cause when such trouble occurs.

  In the above description, the present invention is described using a temperature measuring device that measures temperature as a physical quantity. However, the physical quantity to be measured is not limited to temperature. The present invention can also be applied when measuring humidity, pH, and the concentration of a specific component instead of temperature. Also, in the clamp-type ammeter, if an IC tag is attached to the device to be measured, the current to be measured can be measured when performing a cyclic inspection while measuring the current by bringing the clamp sensor close to the wire to be measured. And identification information can be associated and captured. The clamp sensor may be attached to the rod, or may be connected to the detection unit by a cord having an appropriate length. Further, when the distance between the measurement objects is long, the present invention can be applied not only to the contact type sensor. For example, the present invention can be applied to an inspection of a lighting apparatus that measures illuminance at a certain distance, and an inspection sensor for preventing a disaster or a fire.

  As described above, the temperature measuring device of the present invention is configured to be able to move integrally by combining a contact-type temperature detection unit and a non-contact type wireless unit that reads identification information. Since the detection unit is brought into contact with the measurement object, the distance between the object and the wireless unit is limited, and the identification information of the measurement object in contact is read by reading the identification information with the wireless unit that makes the distance receivable. It is possible to determine automatically. If the range in which the identification information can be obtained wirelessly is sufficiently small compared to the size of the object, the identification information can be easily distinguished, and the identification information can be automatically limited to that of the measurement object. For this reason, in the measuring apparatus of the present invention, the measured value (temperature) and the identification information obtained at the time of measurement are correlated and output and recorded, so that the operator performs one-push temperature measurement. As a result, it is not necessary to input or select information on the measurement object each time, and a history of temperature measurement for each product can be easily and reliably left.
