  In addition, this portable terminal device has a communication unit that communicates with an IC tag capable of storing measurement information. Therefore, measurement information that is a value obtained by measuring a measurement target can be easily transferred from the portable terminal device to the IC tag. It becomes possible to memorize.

  As described above, the position of the measurement target is placed on the map on the portable terminal device that can write the measurement information or read the measurement information to the IC tag attached to the measurement target such as a flow meter. By displaying in correspondence, the position of the measurement target can be easily grasped visually, so that the workability of the measurer can be greatly improved.

  Further, the measurement information storage unit further stores the measurement information, and based on the measurement information, displays the measurement state of the measurement target on the map displayed on the display unit in an identifiable manner. It becomes easy to grasp the measurement state of the measurement object, that is, measurement completed or unmeasured, and it becomes easy to determine the route for measuring the measurement target that has not been measured.

  Further, the mobile terminal device determines the measurement target to be measured based on the measurement information and the measurement target information, and determines the order to be measured when there are a plurality of measurement targets to be measured, and the display unit Since the order to be measured is displayed on the map displayed in an identifiable manner, the measurer can easily perform the measurement by following the instructions displayed on the display unit.

  Further, since the usage amount is calculated by calculating the difference between the measurement information read by the IC tag information reading unit and the measurement information input by the input unit, the usage amount can be easily calculated.

  Further, since it is determined whether the measurement information read by the IC tag information reading means is information measured within a predetermined period, even though an object to be measured has already been measured, Further, the measurer can be notified of the possibility of measurement.

  In addition, since it is determined whether or not the calculated usage amount is included in the measurement prediction range of the measurement target calculated based on the past measurement information of the measurement target, this avoids an input error. Is possible.

  The IC tag information writing means reads the identification ID of the IC tag when writing the measurement information of the measurement target to the IC tag, and whether the IC tag of the identification ID is an IC tag attached to the measurement target. Therefore, it is possible to avoid erroneously writing measurement information to IC tags attached to different objects to be measured.

  A measurement system according to an embodiment of the present invention is attached to a plurality of objects to be measured or in the vicinity thereof, an IC tag capable of storing measurement information, and a portable terminal capable of transmitting and receiving data by a communication unit communicating with the IC tag Device.

  As a result, the measurer can write measurement information or read measurement information to an IC tag attached to the measurement target such as a flow meter using the portable terminal device. As a result, measurement information can be written to the IC tag each time measurement is performed, so that the previous measurement value need not be stored in the mobile terminal device in advance. Therefore, in the case of a portable terminal device that can write measurement information to or read measurement information from an IC tag, the past measurement information stored in the IC tag and the measurement value measured this time are used to determine the measurement target. The amount used can be measured.

  In addition, the mobile terminal device stores a display unit that displays information, a measurement information storage unit that stores measurement target information including position information of the measurement target, and map information for displaying a map on the display unit. A map information storage unit and display control means for displaying the measurement target on the map displayed on the display unit in a distinguishable manner based on the measurement target information.

  As a result, the measurer can easily grasp the position of the measurement target visually based on the position of the measurement target displayed in correspondence with the map on the display unit of the mobile terminal device. The workability of the worker can be greatly improved.

  Therefore, it is not necessary to know where the measurement target is to be measured, and the measurement workability of the measurer can be improved.

  Here, the measurement target includes a flow meter such as a water meter, an electric meter, or a gas meter. An IC tag is a chip-type device, also called a wireless tag, RF tag, RFID, etc., which operates by generating power from radio waves received by an antenna and storing data received via an antenna. The stored data is transmitted through the antenna.

  Further, the IC tag stores an identification ID and position information as information to be measured. By reading the identification ID or position information, the position of the IC tag is displayed on the map displayed on the display unit. It can also be.

  That is, the control unit of the portable terminal device functions as an IC tag position detection unit, and the IC tag position detection unit receives the identification ID and the position information stored in the IC tag, and also determines the position on the map from the received information. The position of the IC tag currently communicating or the information of the current position can be displayed on the map that is detected and displayed on the display unit.

  Therefore, the IC tag currently measured can be displayed on the map, and as a result, it becomes easy to grasp the current position. The IC tag currently measured may be displayed as the current position instead of being displayed on the map.

  Here, the identification ID means a serial number unique to each IC tag, and may be in any format as long as it can identify each IC tag and can be stored in the IC tag.

  In addition, the IC tag stores information on the owner or contractor as the measurement target information, and the conventional information is obtained by reading and displaying the owner information or contractor information by the mobile terminal device. Therefore, it becomes possible to easily grasp the owner or contractor of the measurement target that has been difficult to measure. In addition, since the measurement target owner and the measurement information are associated with each other and stored in the IC tag or the portable terminal device, the measurement person performs measurement without being particularly aware of the measurement target owner or the like. It becomes possible.

  Further, by storing the measurement information in the measurement information storage unit, it becomes easy to grasp the measurement state of the measurement target, which has been difficult in the past, i.e., already measured or unmeasured. It becomes easy to determine the path to be measured.

  That is, the control unit of the mobile terminal device measures whether the measurement target has been measured or not measured on the map displayed on the display unit, based on measurement information including measured and unmeasured information for each measurement target. It functions as a display control means for displaying the state in an identifiable manner.

  In addition, the control unit of the mobile terminal device includes non-measurement target determination means for determining a measurement target to be measured based on measurement information including measured and unmeasured information and measurement target information, and a target to be measured. When there are a plurality of measurement objects, it has route determination means for determining the order of measurement, and functions as display control means for displaying the order of measurement on the map displayed on the display section in an identifiable manner.

  Here, the display of the order to be measured can be performed by sequentially displaying the position of the measurement target to be measured next in an identifiable manner on the map, or by displaying the number of the order to be measured on the map. It becomes possible.

  Then, in order to make it possible to identify the measurement target, its measurement state, or the order to be measured on the map, the color of the measurement target can be made different from another or blinked. Further, the measurement target may be displayed on the map by arranging a predetermined figure on the map.

  In addition, when the position of the measurement target is on the farmland, the planting information of the farmland where the measurement target is located is added as the measurement target information, and the planting information is displayed on the map. The person can identify the planting state of the measurement area, and the measurement work becomes easy.

  Here, planting information includes cigarettes, sugar cane, onions, peppers, pineapples, etc., and it is difficult to find the current position and measurement target because there are many measurement targets on a vast farmland Even so, such difficulty can be greatly reduced by displaying the planting information of the farmland where the measurement target is located on the map together with the measurement target.

  In addition, the mobile terminal device includes an IC tag information reading unit that reads the identification ID and measurement information stored in the IC tag via the communication unit, an input unit that inputs a value obtained by measuring the measurement target, and an input IC tag information writing means for writing the measurement information input by the means to the IC tag via the communication unit.

  Therefore, the measured information can be stored in the IC tag, and the meter value, which is the previously measured value, can be obtained by reading the measurement information stored in the IC tag. Therefore, the usage amount (difference between the value measured last time and the value measured this time) can be easily calculated by measuring the measurement value of the measurement target.

  In particular, since it has a calculation means for calculating the amount of use by calculating the difference between the measurement information read by the IC tag information reading means and the measurement information input by the input means, the calculation is facilitated. .

  Further, by storing information such as the usage amount, measurement date and time, and the measurer in addition to the measurement value, the IC tag can be provided with a more convenient measurement system.

  For example, by storing information on the measurement date and time in the IC tag 4, for example, the following control is possible.

  In other words, the portable terminal device has a duplicate measurement determination unit that determines whether or not the measurement information read by the IC tag information reading unit is information measured within a predetermined period (for example, within one week). The determination result by the duplicate measurement determination means is displayed on the display unit.

  By configuring in this way, it is possible to notify the measurer of the possibility of further measurement even though an object to be measured is already measured. In particular, when the mobile terminal device is lost, it is effective when the measurement is performed with another mobile terminal device.

  Then, by canceling the storage operation of the measured value or the like to the IC tag in accordance with the judgment of the measurer, an erroneous input by the measurer can be avoided.

  Further, the mobile terminal device has measurer determination means for acquiring measurer information stored in the IC tag and determining whether the measurer information acquired in this way is different from the measurer. The determination result by the person determination means is displayed on the display unit.

  By comprising in this way, it becomes possible to avoid measuring by the measurer who should not measure. Furthermore, it is more reliable if a measurer who should not perform measurement does not store the measurement value in the IC tag.

  In addition, the mobile terminal device includes an input error determination unit that determines whether or not the difference calculated by the calculation unit is included in the measurement prediction range of the measurement target calculated based on the past measurement information of the measurement target. Have.

  The control unit functions as a display control unit that displays the determination result by the input error determination unit on the display unit, thereby making it possible to avoid an input error.

  In addition, the measurement system according to the present embodiment includes a computer device that manages measurement target information and measurement information, and transmits and receives measurement target information and measurement information to and from the portable terminal device. The entire measurement system can be managed by the device.

  And the portable terminal device can receive measurement object information from this computer apparatus, and can transmit the measurement information which is a result measured based on the measurement object information to the computer apparatus.

  Further, the storage unit 26 stores a storage area as a measurement information storage unit that stores measurement target information including the identification ID and position information of the flow meter 3, and map information for displaying a map on the display unit 24. It has a storage area as a map information storage section and a storage area as a measurement information storage section for storing measurement information related to each flow meter 3, and is composed of a nonvolatile rewritable hard disk or the like.

  As information to be measured, in addition to the identification ID and the position information of the flow meter 3, there are a user and an owner of a house or land provided with the flow meter 3. In addition, when the land provided with the flow meter 3 is farmland, there is cropping information (cigarette, corn, etc.) indicating how the farmland is planted.

  The measurement information includes measurement date / time, measurement value, usage amount, and information on the measurer, and receives past measurement information from the computer device 1 before measurement, or from the input unit 23 of the portable terminal device 2. The data is stored in the storage unit 26 by input.

  The control unit 27 includes a CPU, a RAM, a ROM, and the like. When the CPU reads out and executes a program stored in the ROM, the above-described display control unit, unmeasured object determination unit, route determination unit, IC It functions as various means such as tag information reading means, computing means, IC tag information writing means, duplication measurement judging means, input error judging means and the like.

  Note that a general-purpose PDA (Personal Digital Assistant) or a mobile personal computer can be used as the mobile terminal device 2 by installing a dedicated program and attaching a wireless card for communication with the IC tag 4. The IC tag read writer may be used.

  Next, the functional configuration of the computer apparatus 1 will be specifically described with reference to FIG. FIG. 3 is a functional configuration diagram of the computer apparatus 1 in the present embodiment.

  As shown in FIG. 3, the computer device 1 includes a first communication unit 11 as a communication unit for wirelessly communicating with the IC tag 4, a second communication unit 12 for communicating with the mobile terminal device 2, and a mobile terminal For data transmission / reception with the device 2 and the IC tag 4, an input unit 13 as an input means for inputting and selecting information, a display unit 14 for displaying various information, and a warning sound are output. For example, a database 16 for storing measurement target information, measurement information, and map information, and a control unit 17 for controlling the entire computer device 1.

  As described above, the computer device 1 stores in the database 16 information to be measured, that is, the identification ID of the flow meter 3, the position thereof, or the information of the contractor (the user of the flow meter, the owner of the land, the house, etc.). At the same time, the measurement value of each flow meter 3, the amount used, the measurement date and time, and the measurement information such as the measurer are also stored and managed in the database 16. Further, map information of an area where the flow meter 3 to be measured exists is also stored in the database 16.

  The database 16 also stores measurer measurement information associated with the flow meter 3 to be measured for each measurer. Therefore, the measurer connects the computer device 1 and the portable terminal device 2 via the second communication units 12 and 22, and inputs the measurer's ID and password from the portable terminal device 2. Measurement target information for performing measurement work, measurement information, a map of a region to be measured, and the like can be downloaded from the apparatus 1.

  Further, the measurer can upload the measurement information stored in the mobile terminal device 2 to the database 16 of the computer device 1 via the second communication units 12 and 22.

  Further, the computer device 1 can store information to be measured such as an identification ID in the IC tag 4 to be attached to the new flow meter 3 through the first communication unit 11 by operating the input unit 13. .

  Thus, the computer device 1 functions as a main system in the measurement system S, and the measurer exchanges various data for measurement between the portable terminal device 2 and the computer device 1. The workability of measurement can be improved.

  Next, the functional configuration of the IC tag 4 will be specifically described with reference to FIG. FIG. 4 is a functional configuration diagram of the IC tag 4 in the present embodiment.

  As shown in FIG. 4, the antenna 40, the communication unit 41 for communicating with the computer device 1 or the portable terminal device 2 via the antenna 40, and the operation of the IC tag 4 by electrically converting the radio wave received by the antenna 40. It has a power supply unit 42 that generates electric power, a storage unit 43 that can store measurement target information and measurement information, and a control unit 44 that controls the entire IC tag 4.

  The communication range by the communication unit 41 is set to a minimum so as not to overlap with the communication ranges of other IC tags 4 as much as possible when a plurality of flow meters 3 are close to each other. In the present embodiment, the communication range (maximum communication range) is 50 cm around the antenna 40.

  Note that the communication unit 41 can be configured to be able to variably control the communication range under the control of the control unit 44.

  That is, the communication range is increased when transmitting the measurement target information stored in the storage unit 43, and the communication range is decreased for a predetermined period when transmitting / receiving the measurement information stored in the storage unit 43.

  By controlling the communication range in this way, the IC tag 4 can inform the portable terminal device 2 of its presence over a wide range, and once data is written from the portable terminal device 2 to the IC tag 4 or IC When there is a request for reading data from the tag 4, the communication range is reduced for a predetermined period, so that erroneous measurement can be avoided even when the flow meter 3 is close.

  In the storage unit 43, information such as identification ID, position information, owner, user, etc. is stored in the predetermined area as information to be measured, so that information leaks even if the information is read out. It is possible to greatly reduce the risk of Note that the storage area can be configured so that the measurement target information cannot be rewritten, thereby preventing the measurement information from being rewritten by a malicious third party.

  The storage unit 43 stores, as measurement information, information related to the measurement date and time, the measurement value, the amount used, and the measurement person, in response to a write request from the mobile terminal device 2.

  Thus, since the IC tag 4 is configured to store the measurement target information such as the identification ID and the measurement information such as the measurement value, it is easy to identify the flow meter 3 that is the measurement target. The work burden on the measurer can be reduced.

  The IC tag 4 is provided with a display means such as an LED and a sound wave output means such as a pressure sound body, so that when the radio wave is received from the portable terminal device 2, light or sound is output from such a notification means. May be. In this way, it becomes easy for the measurer to find the flow meter 3. In addition, when the radio wave from the mobile terminal device 2 cannot be received, the power generation unit 42 cannot generate power and there is no output from the notification means, so that the IC tag 4 is rarely found by a third party and mischievous. In particular, if the notification means can output only when a predetermined code is transmitted from the mobile terminal device 2, the possibility of such mischief can be reduced as much as possible.

  Regarding the measurement system S configured as described above, a specific operation of the mobile terminal device 2 which is a characteristic part in the present embodiment will be described with reference to the drawings. 5 to 22 are diagrams showing display examples on the display unit of the mobile terminal device 2 in the present embodiment, and FIGS. 23 to 30 are operation flowcharts of the mobile terminal device 2 in the present embodiment.

  As shown in FIG. 23, when the mobile terminal device 2 is first turned on, the control unit 27 displays an ID / password input screen on the display unit 24 as shown in FIG. 5 (step S1).

  Thereafter, the control unit 27 determines whether or not the measurer has operated the input unit 23 to input the ID and password (step S2).

  If it determines with having input ID and a password (step S2: Yes), the control part 27 will collate input ID and password (step S3). If it is determined that the correct ID and password have not been input (step S3: No), a verification NG screen is displayed (step S4).

  On the other hand, when it is determined that the measurer has input the correct ID and password (step S3: Yes), the control unit 27 displays a menu selection screen on the display unit 24 as shown in FIG. 6 (step S5).

  In this menu selection screen, any of a measurement operation, a measurement position search operation, a new registration operation, and a data transmission / reception operation can be selected by operating the input unit 23. The control unit 27 can be selected by operating the input unit 23. It is determined whether or not a selection has been made (steps S6, S8, S10, and S12).

  If it is determined that the measurement operation is selected (step S6: Yes), the measurement process is executed by the control unit 27 (step S7). If it is determined that the measurement position search operation is selected (step S8: Yes), the measurement position is determined. When the search process is executed (step S9) and it is determined that the new registration operation is selected (step S10: Yes), the new registration process is executed (step S11) and when it is determined that the data transmission / reception operation is selected (step S12: Yes), data transmission / reception processing is executed (step S13).

  As shown in FIG. 24, the measurement operation in step S7 is performed by first measuring the position of the flow meter 3 on the map displayed on the display unit 24 based on the measurement target information and measurement information stored in the storage unit 26 by the control unit 27. And the measurement state are displayed in an identifiable manner (step S20).

  A display example of the screen displayed on the display unit 24 by the control unit 27 is shown in FIG. In this display example, a map of five blocks A to C, F, and G is displayed, and each block is color-coded according to the measurement state of each block.

  In the present embodiment, six measurement states are described as examples of the measurement state, measured, during measurement, next measurement, re-measurement, unmeasured, and out of target, but are not limited thereto. This measurement state is determined by the control unit 27 based on the measurement target information and measurement information stored in the storage unit 26. The detailed operation of the measurement area display process will be described later with reference to FIG.

  As described above, since the position and measurement state of the flow meter 3 can be identified on the map, the measurer can easily determine the position and measurement state of the flow meter 3 to be measured using the mobile terminal device 2. I can grasp it.

  When the measurement process is started, the control unit 27 displays the position and state of the flow meter 3 on a wide range map in units of blocks (for example, in units of blocks) as shown in FIG. An area including a plurality of blocks is displayed on the display unit. FIG. 7 shows that only the area of the A block is a measurement target and is being measured, and the other B block, C block, F block, and G block are not measurement targets.

  Next, the control unit 27 determines whether or not a display area change request has been made by an operation on the input unit 23 by the measurer (step S21).

  The display area change request includes a map enlargement display request and a map reduction display request. In the case of a map enlargement display request, an area that requires detailed display in the map displayed on the display unit 24 is designated by an operation of the input unit. (Step S21: Yes). For example, when displayed as shown in FIG. 7, by selecting the A block, an enlarged view of the A block shown in FIG. 7 is displayed as shown in FIG. Furthermore, by selecting the property E in such a display state, as shown in FIG. 9, an enlarged view of the property E shown in FIG. 8 is displayed.

  7 to 9 show examples of display when the flow meter 3 attached to the house is measured. In the case of land, the display is as shown in FIGS. In this case, the display is as shown in FIGS.

  That is, when the flow meter 3 is attached to the land, a wide range display is displayed as shown in FIG. 10, and a narrow range display is displayed as shown in FIG. In this narrow range display, the display control means displays where the flow meter 3 is located on the land of each lot number in a predetermined figure (here, circular), so that the measurer can change the flow rate. The time for searching for the meter 3 can be greatly reduced. Further, the control unit 27 changes the color of the predetermined figure depending on whether the flow meter 3 has been measured or not. Therefore, even if there are a plurality of the same lot number, the measurer can easily grasp the measurement state, and therefore, it is possible to prevent the measurement omission.

  Further, when the flow meter 3 is attached to the farmland, a wide range display is displayed as shown in FIG. 12, and a narrow range display is displayed as shown in FIG. In this narrow range display, the display control means displays where the flow meter 3 is located in the land of each lot number in the same manner as in the case of the above land. Display or color display is possible. As a result, the time required for the measurer to look for the flow meter 3 can be greatly reduced.

  Subsequently, the control unit 27 determines whether or not there is a measurement request (step S22). Then, when the display state is in a narrow range as shown in FIG. 9, FIG. 11, FIG. 13, etc., the measurer operates the area of the individual flow meter 3 by operating the input means (for example, each house area in FIG. 11 or each place number in FIG. 13 is designated, a screen for selecting whether to start reading the IC tag 4 is displayed on the display unit 24 as shown in FIG. When the reading start of the IC tag 4 is selected by the input unit 23, the control unit 27 determines that there is a measurement request (step S22: Yes), and starts the IC tag reading process (step S23). A specific operation of the IC tag reading process will be described later with reference to FIG.

  In the IC tag reading process, the control unit 27 reads information stored in the IC tag 4 via the first communication unit 21 and displays the read information and the like on the display unit 24 as shown in FIG.

  Then, when a measurement input request is made by an operation of the input unit 23 by the measurer, the measurement result registration process is executed by the control unit 27 (step S24). This measurement input request is made, for example, by selecting by clicking the [current measurement input] button in FIG. 15 when the display unit 24 has a display as shown in FIG. A specific operation of the measurement result registration process will be described later with reference to FIG.

  Here, the specific operation of the measurement region display process in step S20 will be described with reference to FIG.

  In the measurement region display process, first, the control unit 27 determines the measurement state of each flow meter 3 based on the measurement information read from the storage unit 26, and detects the unmeasured flow meter 3 (step S30). The control unit 27 can also detect an unmeasured object based on the measurement date and time of each flow meter 3 stored in the storage unit 26, and whether or not each flow meter 3 has been measured in the storage unit 26. Information may be stored and an unmeasured object may be detected by detecting this information. When an unmeasured object is detected based on the measurement date and time of the flow meter 3, a flow meter 3 for which measurement information up to a predetermined period (for example, one week ago) is not stored in the storage unit 26 is detected as an unmeasured object. It is desirable to do.

  Next, the control unit 27 determines a display area (step S31). In this determination, the display area is determined based on whether the next display should be a wide range display or a narrow range display. For example, the property E is selected in the display state of FIG. In this case, a narrow range display as shown in FIG. 9 is determined as the display area.

  And the control part 27 reads the map information of the display area determined by step S31 from the memory | storage part 26 (step S32).

  In addition, the control unit 27 reads the position and measurement state of the flow meter 3 included in the display area determined in step S31 from the storage unit 26 (step S33).

  Furthermore, the control part 27 determines the order which should be measured, when there exist two or more flow meters 3 located in the display area determined by step S31 (step S34). In principle, the control unit 27 calculates a route through which the measurer can move at the shortest distance in order to measure the unmeasured flow meter 3, and in the case of a property such as a building, the control unit 27 moves for each floor. Calculate the possible routes and determine the order to be measured. In addition, although it is possible to measure the flow meter 3 arranged in a house such as a building even when the sun goes down, it becomes difficult to measure the flow meter 3 installed in a place such as farmland when the sun goes down. Therefore, the control unit 27 may perform calculation of a measurement route that prioritizes daytime.

  And the control part 27 reads the map information which should be displayed from the memory | storage part 26, and while producing | generating a map layer, in order to display information on this map layer, the to-be-measured object which shows the position and usage condition of the flow meter 3 A layer is produced | generated (step S35) and each display layer is displayed on the display part 24 (step S36).

  In addition, as the measurement state, six states that are already measured, during measurement, next measurement, remeasurement, unmeasured, and out of target are displayed in color, and “measured” exists as the measurement target information, It indicates that measurement information of the measurement date and time up to a predetermined period is stored in the storage unit 26, and “under measurement” exists as measurement target information and is currently being measured or is currently the first by the route determination means. The next measurement is shown, and “next measurement” indicates the next measurement by the route determination means. “Unmeasured” indicates what should be measured after the next measurement by the route determination means, and “re-measurement” indicates that the re-measurement is necessary because the measurement operation is completed during the measurement. “Non-target” indicates that the information to be measured does not exist.

  Next, a specific operation of the IC tag reading process in step S23 will be described with reference to FIG.

  As shown in FIG. 26, when the IC tag reading process is started, the control unit 27 sends a request for reading the identification ID and measurement information stored in the IC tag 4 via the first communication unit 21 to the IC tag. 4 (step S40).

  Then, the control unit 27 determines whether or not the identification ID can be read (step S41). That is, it is determined whether or not communication with the IC tag 4 is possible, or communication is possible but identification ID cannot be received, and it is determined that communication with the IC tag 4 cannot be performed or identification ID cannot be received (step S41: No). Then, a communication disabled display with the IC tag 4 or an IC tag recognition disabled display is performed (step S42).

  On the other hand, if it is determined in step S41 that the IC tag 4 can be communicated and the identification ID can be received (step S41: Yes), the control unit 27 can read the measurement information from the IC tag 4. Is determined (step S43).

  If it is determined that the measurement information cannot be read from the IC tag 4 (step S43: No), the control unit 27 displays that the measurement information cannot be read from the IC tag 4 (step S44).

  On the other hand, when it is determined in step S43 that the measurement information can be read from the IC tag 4 (step S43: Yes), the control unit 27 further includes a predetermined period (for example, 3 days) of the measurement information acquired from the IC tag 4. It is determined whether there is previous measurement information (step S45).

  Then, when the control unit 27 determines that the measurement information read from the IC tag 4 includes measurement information within a predetermined period (step S45: Yes), the control unit 27 has a possibility of duplicate registration. A warning screen to that effect is displayed on the display unit 24 (step S46), and further, whether or not to continue the measurement is displayed, and the measurer determines whether or not to continue the measurement (step S47).

  When the selection to continue measurement in step S47, that is, when new measurement information registration is performed by the input unit 23 (step S47: Yes), the measurement information read from the IC tag 4 in step S45 includes measurement information within a predetermined period. If it is determined that the information has not been received (step S45: No), the control unit 27 compares the information stored in the storage unit 26 with the information received from the IC tag 4 in step S40. It is determined whether or not (step S48). This comparison is performed by comparing the latest measurement date and time measurement information related to the IC tag 4 stored in the storage unit 26 with the latest measurement date and time measurement information read from the IC tag 4. In this way, the comparison processing speed is improved.

  In step S48, when the control unit 27 determines that the measurement information stored in the storage unit 26 and the measurement information read from the IC tag 4 do not match (step S48: No), that fact, that is, in the storage unit 26. A display indicating that the stored measurement information does not match the measurement information read from the IC tag 4 (measurement information mismatch display) is performed (step S49). Further, the control unit 27 displays on the display unit 24 a selection screen as to whether or not to cancel such a mismatch state, thereby allowing the measurer to determine whether or not to cancel such a mismatch ( Step S50).

  When the measurer operates the input means to make a request for eliminating such inconsistency (step S50: Yes), the control unit 27, when there is new measurement information in the IC tag 4, The measurement information is additionally stored in the storage unit 26. Conversely, if the measurement information stored in the storage unit 26 is new, the information is written to the IC tag 4 (step S51).

  As described above, when there is new measurement information in the IC tag 4, the measurement information of the IC tag 4 can be stored in the storage unit 26 of the portable terminal device 2. For example, the measurement information is written in the IC tag 4. Even if the portable terminal device 2 is lost before uploading the measurement information to the computer apparatus 1 later, the portable terminal device 2 can read the measurement information of the IC tag 4 to recover the data. . For example, when the measurement information of “measurement date: xx May 20th, measurement value: 100” is stored in the IC tag 4, the mobile terminal device 2 reads the measurement information, thereby measuring the storage unit 26. As information, “measurement date: xx May 20, year measurement value: 100” can be stored. That is, even if the date of communication with the IC tag 4 is June 20, xx, measurement information measured on May 20, xx can be stored in the storage unit 26 of the mobile terminal device 2.

  In step S48, when it is determined that the measurement information stored in the storage unit 26 matches the measurement information read from the IC tag 4 (step S48), the measurer does not make a request for eliminating such a mismatch (step S48). S50: No) or when the data mismatch is resolved in step S51, the control unit 27 relates to the IC tag 4 based on the identification ID of the IC tag 4 communicated in step S40 as shown in FIG. A map and information to be measured are displayed (step S52). Note that the screen shown in FIG. 21 may be displayed before the screen shown in FIG. Moreover, when the arrangement of the flow meter 3 is land, a display as shown in FIG. 22 can be made.

  Further, in the state displayed on the display unit 24 as shown in FIG. 15, when the measurer selects the [current measurement input] button in FIG. A measurement value input screen is displayed on the display unit 24. The previous measurement value and the previous measurement date are displayed based on the measurement information acquired from the IC tag 4 in step S40, but such display is performed based on the measurement information stored in the storage unit 26. You may make it perform.

  Next, a specific operation of the measurement result registration process in step S24 will be described with reference to FIG.

  As shown in FIG. 27, when the measurement result registration process is started, the control unit 27 determines whether or not the measurer inputs the measurement result from the input unit 23 on the measurement input display screen as shown in FIG. Determination is made (step S53).

  When it is determined that the measurement result, that is, the measurement value of the flow meter 3 has been input (step S53: Yes), the control unit 27 reads the previous time from the IC tag 4 (or retrieves it from the storage unit 26). The usage amount is calculated by calculating the difference between the measurement value and the input measurement value (step S54).

  Next, the control unit 27 extracts past measurement information for the IC tag 4 being measured from a storage area as a measurement information storage unit of the storage unit 26, and calculates a measurement prediction range, that is, a use amount prediction range. Further, the control unit 27 determines whether or not the usage amount calculated in step S54 is included in the prediction range (step S55). The prediction range is not calculated by the mobile terminal device 2, but is calculated by the computer device 1 and stored in the storage unit 26 of the mobile terminal device 2, and the prediction stored in this way in step S55. A range may be used.

  When it is determined that the usage amount is not within the predicted range (step S55: No), the control unit 27 displays on the display unit 24 that the measurement value input in step S53 indicates the possibility of an input error (step S55). S56) When it is determined that the usage amount is within the prediction range (step S55: Yes), it is selected whether or not to store the measurement information including the measurement value input in step S53 on the display unit 24 in the storage unit 26. A registration availability display screen is displayed (step S57). In addition, after the process of step S56 is completed, the process of step S57 is executed by a predetermined operation on the input unit by the measurer.

  Next, the control unit 27 determines whether or not the measurer has operated the input unit 23 and has selected to store the measurement information including the measurement value input in step S53 in the storage unit 26 (step S58). ).

  In step S58, when the measurement information is not selected to be stored in the storage unit 26 and the IC tag 4 (step S58: No), the process returns to the process of step S53. On the other hand, when such selection is performed (step S58). S58: Yes), the control unit 27 communicates with the IC tag 4 and determines whether or not the identification ID transmitted from the IC tag 4 matches the identification ID of the IC tag 4 attached to the measurement target being measured. Determination is made (step S59).

  If it is determined in step S59 that the identification ID of the IC tag 4 does not match the identification ID of the IC tag 4 attached to the measurement target being measured (step S59: No), the control unit 27 registers the registration target (write target). ) Error display and an alert sound is output from the speaker 25. The registration target error is displayed by blinking the position of the measurement target being measured on the map displayed on the display unit 24, the land where the measurement target is provided, and the like from the IC tag 4 in step S59. This can be done by blinking and displaying the position of the measurement target corresponding to the transmitted identification ID and the land where the measurement target is provided. Although not shown, if the control unit 27 determines in step S59 that communication with the IC tag 4 is not possible, a communication disabled display is displayed on the display unit 24.

  Thus, if the portable terminal device 2 determines that the identification ID of the IC tag 4 does not match the identification ID of the IC tag 4 attached to the measurement target being measured, the portable terminal device 2 does not write the measurement information to the IC tag. Therefore, it is possible to prevent the measurement information from being written to the IC tag 4 that is not related to the measurement information. In addition, when it does not match the identification ID of the IC tag 4, a message to that effect is displayed to alert the measurer, so that the measurer can easily grasp that fact. Further, since the position of the measurement target corresponding to the identification ID transmitted from the IC tag 4 is displayed in such a case, the measurer communicates with the IC tag 4 attached to which measurement target. You can easily grasp what is happening.

  On the other hand, when it is determined in step S59 that the identification ID of the IC tag 4 matches the identification ID of the IC tag 4 attached to the measurement target being measured (step S59: Yes), the control unit 27 further controls the IC tag 4. It is determined whether there is a margin for writing measurement information (step S61). If it is determined that there is no margin (step S61: No), a control signal is transmitted from the first communication unit 21 to the IC tag 4 and the oldest is transmitted. The measurement data is deleted from the storage unit 43 (step S62).

  Thereafter, when there is room to write measurement information to the IC tag 4 (step S61: Yes) or when the process of step S62 is completed, the control unit 27 writes the measurement value input in step S53 to the IC tag 4 and registers it. In step S63, the usage amount, the measurement date and time, and the measurer are written and registered in the storage unit 26 (step S64).

  Next, a specific operation of the measurement position search process in step S9 will be described with reference to FIG.

  As shown in FIG. 28, when the measurement position search process is started, the control unit 27 displays a search screen as shown in FIG. 17 (step S70).

  Then, the control unit 27 waits for the [Search] button as shown in FIG. 17 to be operated after the address for search or the like is input from the input unit 23 (step S71).

  When the [Search] button is operated in step S71, the control unit 27 determines whether or not an address that matches the input address exists in the measurement target information stored in the storage unit 26 (step S71). S72).

  If it is determined that there is no matching address (step S72: No), the address group in the area close to the address input in step S71 is displayed (step S73), and one address is selected from the address group. (Step S74).

  If it is determined in step S72 that there is a matching address (step S72: Yes), or if it is determined in step S74 that one address is specified (step S74: Yes), as shown in FIG. Information on the selected address (such as a measurement number, an address, a building name, a room number, and a contractor name serving as an identification ID) is displayed (step S75). When the flow meter 3 is on farmland, a measurement target screen as shown in FIG. 19 is displayed. Further, in the state where the screen to be measured shown in FIG. 19 is displayed, by operating the [Add] button, a cropping addition screen as shown in FIG. 20 is displayed and cropping information (cropping content) is added. Can do.

  Thereafter, the control unit 27 determines whether or not to select measurement result input (step S76). The selection of the measurement result input is performed, for example, by clicking a [current measurement input] button in FIG.

  When the measurement result input is selected (step S76: Yes), the process proceeds to step S60. When such a selection is not made (step S76: No), the measurement position search process ends.

  Next, the specific operation of the new registration process in step S11 will be described with reference to FIG.

  As shown in FIG. 29, when the new registration process is started, the control unit 27 displays a new registration screen for the IC tag 4 (step S80), and includes identification ID, position information, and user as measurement target information. Then, it waits for registration information such as the owner to be input (step S81).

  When the input of the measurement target information is completed (step S81: Yes), the control unit 27 performs a process of writing the measurement target information input in step S81 via the first communication unit 21 to the IC tag 4 ( Step S82).

  Then, the control unit 27 determines whether or not communication with the IC tag 4 is possible (step S83), and when communication is not possible (step S83: No), the display unit 24 displays an unregistration display on the IC tag 4. (Step S84).

  If the control unit 27 determines that the IC tag 4 is communicable (step S85: Yes), the control unit 27 further determines whether the measurement target information is already registered in the IC tag 4 (step S85).

  If it is determined in step S85 that the measurement target information has already been registered in the IC tag 4 (step S85: Yes), the control unit 27 overwrites the measurement target information in the IC tag 4, that is, re-registers. It is determined whether an operation has been performed or whether an unregistered operation has been performed (step S86).

  And if it determines with re-registration operation having been performed in step S86 (step S86: Yes), the to-be-measured object information input by step S81 will be memorize | stored in the memory | storage part 43 of IC tag 4 (step S87).

  Thus, since the measurement target information can be stored in the IC tag 4 by the portable terminal device 2, the measurer can easily attach the IC tag 4 to the measurement target.

  Further, the control unit 27 of the mobile terminal device 2 can extract the measurement target information and past measurement information from the storage unit 26 and write the information on the IC tag 4. As described above, since the measurement target information and past measurement information can be written to the IC tag 4, even if the IC tag 4 is removed from the measurement target by a third party, the information is removed. The IC tag 4 storing the same information as the IC tag 4 can be generated, and the IC tag 4 can be reissued. As a result, since the IC tag 4 can be easily reissued at the measurement site without reissuing the IC tag 4 by the computer device 1 as a host, the IC tag 4 is removed or breaks down in an emergency. Even if it exists, the correspondence becomes easy.

  Next, a specific operation of the data transmission / reception process in step S13 will be described with reference to FIG.

  As shown in FIG. 30, when the data transmission / reception process is started, the control unit 27 displays a data transmission / reception selection screen (step S90) and waits for the measurer to select data transmission or data reception (step S91, S92).

  When the control unit 27 determines that data reception is selected by operating the input unit 23 (step S92: Yes), the control unit 27 requests the computer device 1 that is a host to perform a data transmission operation, and the computer device 1 in response to this request. Wait for a response from (step S93).

  When the reception data selection screen information is transmitted from the computer device 1 (step S93: Yes), the control unit 27 displays the reception data selection screen on the display unit 24 (step S94), and the measurement unit input unit 23 displays the reception data selection screen information. Waiting for selection of received data by operation (step S95).

  Thereafter, selection of received data (for example, selection of measurement target information and measurement information to be measured on the next day) is performed by an operation of the input unit 23 of the measurer (step S95: Yes), and the selected received data is selected. Is sent to the computer apparatus 1 (step S96), and data reception from the computer apparatus 1 is waited for this request (step S97).

  When data is received from the computer apparatus 1 in step S97, the received data is stored in the storage unit 26 (step S98).

  In step S91, when the control unit 27 determines that data transmission is selected by operating the input unit 23 (step S91: Yes), the control unit 27 displays a transmission data selection screen on the display unit 24 (step S99). Then, it waits for selection of data to be transmitted on the transmission data selection screen (step S100). When data to be transmitted is selected (step S100: Yes), the control unit 27 transmits the selected data to the computer device 1 that is a host (step S101).

  In this data transmission / reception processing, the mobile terminal device 2 and the computer device 1 are connected by connecting the second communication unit 22 of the mobile terminal device 2 and the second communication unit 12 of the computer device 1 with a wired cable such as a USB cable. As shown in FIG. 32, the second communication unit 22 of the mobile terminal device 2 and the second communication unit 12 of the computer device 1 are respectively connected to the communication network 5 as shown in FIG. May be. The communication network includes a wireless communication device 6, and the mobile terminal device 2 can communicate with the computer device 1 via the wireless communication device 6.

  Steps S1, S4, S5, S21, S22, S30 to S33, S34, S35, S42, S44, S46, S49, S50, S52, S53, S56, S60, S62, S70, S73, S75, S80, S84. , S90, S94, S99, etc. are controlled as display control means of the control unit 27, steps S2, S3 are control as authentication means of the control unit 27, and steps S6, S8, S10, S12 are control units. Step S30 is a control as a menu selection detection unit, step S30 is a control as a non-measurement target determination unit of the control unit 27, steps S71, S72, and S74 are a control as a measurement position search unit of the control unit 27. Is the control as the calculation means of the control unit 27, and step S62 is the usage amount prediction range determination means and the input error of the control unit 27. Steps S65, S66, S67, and S82 are controls as IC tag information writing means of the control unit 27, Step S48 is control as data mismatch resolution means of the control unit 27, and Step S45 is Step S34 corresponds to the control of the control unit 27 as the duplicate measurement determination unit, step S34 corresponds to the control of the control unit 27 as the route determination unit, and steps S40, S41, and S43 correspond to the control of the control unit 27 as the IC tag information reading unit. To do.

  Here, the operation of the IC tag 4 will be described more specifically with reference to the drawings. FIG. 31 is an operation flowchart of the IC tag 4.

  As shown in FIG. 31, when the IC tag 4 receives a radio signal having a predetermined frequency from the computer device 1 or the portable terminal device 2, the power of the radio wave received by the antenna 40 is electrically converted by the power supply unit 42. Generate operating power. And the communication part 41, the memory | storage part 43, and the control part 44 are started by the operating electric power produced | generated in this way.

  Thereafter, the control unit 44 waits to receive an information reading request and an information writing request from the computer device 1 or the portable terminal device 2 via the communication unit 41 (steps S200 and S202).

  When the control unit 44 receives the information reading request, the computer unit 1 that has transmitted the information reading request transmits information corresponding to the content of the information reading request among the measurement target information and the measurement information stored in the storage unit 43. It transmits to the portable terminal device 2 (step S201).

  Further, when receiving the information write request, the control unit 44 stores information included in the information write request in the measurement target information area or the measurement information area of the storage unit 43 (step S203).

  If a wireless signal having a predetermined frequency is not transmitted from the computer device 1 or the mobile terminal device 2, the power supply unit 42 cannot generate operating power, and the power is turned off (step S204: Yes). The unit 41, the storage unit 43, the control unit 44, etc. stop their operations.

  Here, the operation of the computer device 1 has the above-mentioned functions similar to those of the mobile terminal device 2 in addition to database management and data exchange with the mobile terminal device 2 as described above. Since it is the same as that of the portable terminal device 2, description is abbreviate | omitted.

  Moreover, as shown in FIG. 33, it is also possible to perform measurement using a portable terminal device 2 ′ that can receive positioning information from GPS.

  That is, as shown in FIG. 34, the mobile terminal device 2 ′ is provided with a GPS unit 28 that can receive positioning information from GPS, and the control unit 27 ′ is based on the positioning information sent from the GPS unit 28. Perform various functions. In addition, the same code | symbol is provided to the same function part as the portable terminal device 2, and the description is abbreviate | omitted.

  For example, the control unit 27 ′ can specify the current position based on the positioning information sent from the GPS unit 28 and perform the measurement area display process (step S 20). More specifically, the map information included in the positioning information is extracted from the storage unit 26 and displayed on the display unit 24, and the measurement target information and measurement information within the range of the map information thus extracted are also stored from the storage unit 26. The position of the measurement target, the measurement status, and the like are displayed on the map taken out and displayed on the display unit 24. By doing so, it becomes easy for the measurer to grasp the measurement position, and the burden on the measurer can be reduced.

  In addition, when the IC tag 4 is newly registered, the control unit 27 ′ can store the information in the IC tag 4 using the positioning information from the GPS as position information. By doing so, the position information of the IC tag 4 can be correctly written to the IC tag 4.
