Description

  The present invention relates to a system for monitoring material properties using a measuring instrument, and more particularly to a system for monitoring and recording the material properties of foodstuffs while managing the location of the foodstuffs in the field of food processing or distribution.

In food processing or distribution, in order to perform hygiene management checks at processing / manufacturing sites and distribution sites from raw materials to final products, measuring instruments for material properties such as temperature, pressure, pH, etc. are introduced at each site process. ing. Here, it is necessary to specify the timing, location, and ingredients that are measured using these measuring instruments.

One solution is to provide a communication function for measuring instruments used in the field, provide a management server, etc., and adopt a method to transmit and record the location, time, measurement target, etc. related to measurement each time measurement is performed. However, it is difficult to provide a measuring instrument with a communication function to a management server or the like because of restrictions on the configuration of the measuring instrument and problems of securing operating power.
In the sensor network system in which the data measured by the communication function is directly sent to the upper layer such as a data recording server, a large amount of unnecessary data is transmitted in addition to the measurement value measured at the timing desired by the monitoring operator. As a result, efficient management is returned and hindered.
For example, when managing the core temperature of ingredients to be heat-processed, the measured value of the timing when the probe of the core thermometer is inserted in an appropriate place should be sent to the upper layer, but simply providing a communication function, the measured value In this method, unnecessary measurement values are transmitted, and complicated data operations are required for management such as separately requiring data for extracting only necessary measurement values.

Against this background, material properties that can be easily adopted within the scope of the configuration of the measuring instrument, have no burden on site workers, and can acquire data necessary for hygiene management etc. at the timing desired by the workers There seems to be a need for other monitoring systems.
Here, the term material physical properties is interpreted more widely than usual, and the temperature, refractive index, sugar content, saltiness, water activity, water content, hardness, viscosity, transparency, color, acidity, amino acid content, weight The material properties include pH, conductivity, elapsed time from a given treatment, speed of running water used in a given treatment, volume, surface area, pressure, CO2 concentration, nitrite concentration, nitrate concentration, presence or absence of metal contamination, etc. Include.
For example, it is widely interpreted as including a medium that supports foodstuffs such as running water in the thawing of frozen tuna and the air in the room that is the site.

In Patent Document 1, video and still image capturing devices including a WEB camera are appropriately controlled, the work to be captured is captured without omission, and images related to a case of a flaw or accident are quickly searched. However, an image monitoring system that realizes high traceability has been proposed.
In the system of Patent Document 1, high traceability is realized by controlling video and still image shooting devices including web cameras with the RFID function, but the monitoring targets acquired by sensors other than video and still image shooting devices It was not a system that realized traceability including information on physical properties of

In the case of a monitoring target such as the fruit shown here, it is necessary to set the monitoring target to the monitoring position instead of setting the probe of the measuring instrument to the target position, but the operator temporarily stores the desired monitoring data In the point which can be performed, it is the same as that of Example 1 and Example 2.

(Slip)
The configuration of the slip 19006 is the same as that of the second embodiment except for the description items and the type of stored data. It consists of a description column in which the product name, shipping number, shipping date and work instruction are written, and a paper type RFID tag. The paper type RFID tag memory stores product data including product name, shipping number, and shipping date.

(Reader) The configuration of the reader 19010 is the same as that of the second embodiment, analyzes the radio waves received by the RFID antenna and the RFID function, reads the stored data, and transmits the read data to the data recording server 19013. It is a structure called a transmission part.

The leader 19011 provided at the second site 19002 also employs the same configuration as the leader provided at the first site.

(Operation flowchart at the first site)
FIG. 21 is a flowchart in the first site.
In a time elapse step 21001, the elapse of time is awaited from the arrival or the previous measurement.
In a measurement step 21002, an operator performs color measurement using the measuring instrument 19003. Color data measured at the timing when an operator puts an appropriate fruit as a sample at a desired appropriate position is temporarily stored.
In the measuring instrument setting step 21003, the worker brings the data conversion storage unit 19003 of the measuring instrument 12003 close to the reader 19010 and starts the reading operation of the reader.
In the temporary storage data reading step 21004, the reader 19010 reads the temporary storage data stored in the data conversion storage unit 19003.
In a measurement data transmission step 21005, the reader 19010 generates measurement data including a site ID that is site identification information for identifying the first site according to a preset measurement data generation method, and transmits the measurement data to the data recording server 19013.

(Temporarily stored color data)
FIG. 22 is a block diagram showing the data structure of temporarily stored data. This is a data structure of measuring instrument ID 22001 and color plot coordinates 22002 indicating colors.

(measurement data)
FIG. 23 is a block diagram showing the data structure of measurement data. The data structure includes an acquisition time 23001, a site ID 23002, a measuring instrument ID 23003, and a color plot coordinate 23004 acquired by a timer (not shown) provided in the reader 19010.

Returning to the operation flowchart of FIG.
In the measurement data acquisition step 21006, the data recording server 19013 acquires the measurement data and temporarily stores it for the data recording 21011 described later.
In the slip setting step 21007, the worker causes the reader 19010 to season the frozen salmon slip 19006 and starts the reading operation of the reader.
In the merchandise data reading step 21008, the reader 19010 executes reading of the merchandise data stored in the paper type RFID tag provided in the slip 19006.
In the product data transmission step 21209, the reader 19010 transmits product data including the shipping time, shipping number, and the like to the data recording server 19013.
In the product data acquisition step 21010, the data recording server 19013 acquires product data and temporarily stores it for data recording 21011 described later.
In the data recording step 21011, the data recording server 19013 records the temporarily stored measurement data and product data in association with each other from the acquisition time, site ID, shipping time, shipping number, etc. as required for traceability. Build a database that provides traceability.
In the set processing time elapsed determination step 21012, the worker determines whether or not the set elapsed time has elapsed. If it is determined that the time has passed, it becomes a carry-out step 21013, and the worker carries out the fruit together with the slip to another predetermined site.
If it is determined that the time has not elapsed, the process returns to the time elapsed step 21001.

(Operations that can be placed at the second site)
The operation at the second site is the same as the operation described for the first site.
Here, the measuring instrument used by the worker for the color measurement of the fruit shares the measuring instrument 19003 used in the first site, but the reader for reading the measured value uses the reader 19011 provided in the second site. Therefore, the traceability about which frozen salmon is measured at which site is ensured.
