Returning to FIG. 2, the device specifying unit 104 acquires position information from the portable information terminal 300, searches the device definition information database 102, and specifies a device 200 that has a predetermined positional relationship with the portable information terminal 300. It is. Specifically, when the device 200 located in a predetermined vicinity region is found with respect to the portable information terminal 300, the device 200 is specified as being “in the vicinity”. For example, when the vicinity region is set to be within the determination distance Δd from the portable information terminal 300, if a certain device 200 is within the determination distance Δd, the device 200 is determined to be “in the vicinity”. Instead of the determination distance, a range surrounded by a plurality of coordinate points composed of latitude and longitude centering on the portable information terminal 300 may be set as the “neighboring region”. In addition, when the mobile information terminal 300 is “near” the device 200 and the device 200 exists in the direction in which the front of the mobile information terminal 300 faces, the device specifying unit 104 has the device 200 in the “front”. The device 200 is specified. For example, the position information transmitted from the portable information terminal 300 is (north latitude, east longitude, direction) = (N3 ′, E3 ′, D3), and the position (N3, E3) and the position (N3 ′, E3 ′) Is equal to or less than the determination distance Δd (d ≦ Δd), the device specifying unit 104 specifies that the temperature sensor with the device ID “1003” is the device 200 existing “near”. When the temperature sensor is located in the direction D3 from the position (N3 ′, E3 ′) of the portable information terminal 300, the device specifying unit 104 has the temperature sensor with the device ID “1003” in “front”. The device 200 is specified. If the portable information terminal 300 is configured to be able to detect the elevation angle, the elevation angle may be added to the position information in addition to the direction. For example, the horizontal direction is 0 °, the upward elevation angle is a positive angle, and the downward elevation angle is a negative angle, which can be used for device identification.

  In the present embodiment, when the device 200 to be monitored is “near” and exists in the direction in which the portable information terminal 300 faces, it is determined as “front”, but this is not a limitation. For example, regardless of the distance between the device 200 to be monitored and the portable information terminal 300, it may be determined as “front” based only on the direction in which the portable information terminal 300 is facing. If portable information terminal 300 (user) is facing the front, the user knows which device 200 he / she is paying attention to, so the user recognizes that device 200 is located at a relatively long distance. Because it can. Further, the distance d2 between the device 200 and the portable information terminal 300 that is a condition for determining “front” may be set to a distance different from the distance d that is determined to be “near”. For example, it is appropriate to set the distance d2 determined to be “front” to be larger than the distance d determined to be “near”. As described above, if the device 200 is facing the front, the user can recognize that the device 200 is disposed at a relatively long distance, but if the device 200 is not facing the front, the device 200 is disposed at a relatively short distance. If not, the user cannot recognize which device 200 is the monitoring target.

As shown in FIG. 6, the monitoring information database 108 exemplarily includes fields of “device ID”, “type”, “measurement control target”, “measurement value”, and “status”. “Device ID”, “Type”, and “Measurement Control Object” are the same information as the fields of the same name in the device definition information database 102, respectively. “Measured value” is information indicating the measured value in the case of a measuring device, and the control amount in the case of a controlling device. “Status” is information indicating a status such as whether the operating state of the device is normal or abnormal. In FIG. 6, as an example, “OK” (normal) or “NG” (abnormal) is stored as the status. In the “status” field, the operation state grasped by the controller 500 (see FIG. 1) through communication with each device 200 is reflected. For example, “Status” is “OK” when the device 200 returns a measurement value within the “appropriate range” of the device definition information database 102, and a measurement value outside the “appropriate range” is returned. It is set to “NG” when it is controlled with a drive amount outside the “appropriate range”. The “status” is “OK” when the operation state of the device 200 is determined to be normal, and is “NG” when it is determined to be abnormal. In FIG. 6, since the temperature sensor with the device ID “1003” is the measurement value within the “appropriate range”, the “status” is “OK”, and the temperature sensor with the device ID “1002” is outside the “appropriate range”. “Status” is “NG” because it is a value, and “NG” because the fan with the device ID “1006” is a measured value (driving amount) that is outside the “appropriate range”. In addition, the flow control valve of the device ID “1004” is controlled within the “appropriate range”, but since the information indicating abnormality is returned, the “status” is set to “NG”.

(Information extraction unit 105)
Returning to FIG. 2, the information extraction unit 105 is a functional block that searches the monitoring information database 108 and extracts monitoring information to be provided for the specified device 200 based on the acquired user definition information. Specifically, the information extraction unit 105 searches the monitoring information database 108 using the device ID as an index for the device 200 determined by the device specifying unit 104 to be “near” or “front”, and displays “ "Measured value" and "status" are extracted and output. For example, when the device 200 determined to be located in “near” is a temperature sensor with the device ID “1003”, the information extraction unit 105 extracts the measurement value “26” and the status “OK” from the monitoring information database 108. To do. When the device 200 determined to be located in the “front” is a fan with the device ID “1006”, the information extraction unit 105 obtains the measurement value (drive amount) “320” and the status “NG” from the monitoring information database 108. Extract.

FIG. 13 is a flowchart for explaining the operation according to the second embodiment. In FIG. 13, steps S121 to S127 are steps executed in the plant monitoring server 100b, steps S321 to S326 are steps executed in the portable information terminal 300b, and steps S201 to S202 are executed in the device 200b. Is a step to be performed. A series of the processes of the flowchart is repeatedly executed at regular intervals or at an arbitrary timing designated by the user. In addition, the processing content of each following step is an illustration, and even if the order of steps is changed, a plurality of steps are processed as one step, or a single step is separated into a plurality of steps. Good.

  In FIG. 13, the user who operates the portable information terminal 300 inputs his / her user identification information from the operation unit 333 after turning on or resetting the power of the terminal. This user identification information is stored in the memory 310 and transmitted to the plant monitoring server 100b at an appropriate timing prior to the monitoring work.

  In step S121, the plant monitoring server 100b determines whether or not user identification information has been acquired. If acquired (step S121: YES), the plant monitoring server 100b moves to step S122, and the user definition information acquisition unit 103 determines that the user definition information has been acquired. User definition information is acquired with reference to the definition information database 101.

  Now, the user wearing the portable information terminal 300b moves in the plant. When the user moves, the mobile information terminal 300b acquires a new current position. That is, in the portable information terminal 300b, in step S321, it is determined whether the position information acquisition unit 308 has acquired new position information. When new position information is acquired (step S321: YES), the process proceeds to step S322, and the newly acquired position information (latitude N, longitude E, direction D) is transmitted to the plant monitoring server 100b. .

  In step S123, the plant monitoring server 100b determines whether or not new position information is acquired from the portable information terminal 300b. If acquired (step S123: YES), the plant monitoring server 100b proceeds to step S124. In step S124, the device specifying unit 104 refers to the device definition information database 102 and specifies the current position and the predetermined position of the portable information terminal 300b specified by the acquired position information (latitude N, longitude E, direction D). The related device 200b is searched. As the device 200b having the predetermined positional relationship, for example, the device 200b located in the “near” or “front” of the current position is searched.

  In step S125, it is determined whether or not there is a device 200b having a predetermined positional relationship with the current position of the portable information terminal 300b. If there is a device 200b having a predetermined positional relationship (step S125: YES), the process proceeds to step S126. In step S126, the information extraction unit 105b searches the device definition information database 102 and extracts “device ID” that is device identification information of the device 200b having a predetermined positional relationship. In addition, “affiliation”, “responsibility”, and “preference” (see FIG. 4) of the record associated with the “user ID” of the user are transferred as user definition information acquired by the user definition information acquisition unit 103. The extracted device identification information and user-defined information are transmitted from the transmission unit 114 to the portable information terminal 300b in step S127.

  In addition, the plant monitoring server 100b complete | finishes the said process routine, when new position information is not acquired in step S123 (step S123: NO). In step S125, when there is no device 200b having a predetermined positional relationship (step S125: NO), the processing routine is terminated.

  In step S323, the portable information terminal 300b determines whether the device identification information and the user definition information are transmitted from the plant monitoring server 100b. If it has been transmitted (step S323: YES), the process proceeds to step S324, and the device communication unit 311 refers to the user definition information to determine whether or not the device 200b specified by the device identification information is the monitoring target. Determine whether. For example, with reference to “Preference” in the user definition information, it is determined whether or not the device 200b having a predetermined positional relationship is registered in “Preference” as a monitoring target of interest to the user. When it is the device 200b to be monitored (step S324: YES), the process proceeds to step S325, and the device communication unit 311 transmits, for example, a device ID as device identification information of the target device. The transmission of the device identification information is for communication preparation on the device 200b side, and is not essential information. For example, instead of the device identification information, communication establishment information indicating that the portable information terminal 300b desires direct communication may be transmitted and received. Alternatively, the process may proceed to a direct monitoring information request step (S326).

  When the device identification information is received in step S201, the device 200b knows that it is a monitoring target and prepares for transmitting the monitoring information.

  In the portable information terminal 300b, the process proceeds to step S326, and the device communication unit 311 transmits a command requesting monitoring information to the device 200b. When receiving the command for requesting the monitoring information, the device 200b transmits its own monitoring information to the portable information terminal 300b in step S202. For example, if the monitored device 200b is a measuring device, the latest measured value is transmitted. If the monitored device 200b is a control device, the current operation status is transmitted as a status.

  In the portable information terminal 300b, when the monitoring information is received, in step S327, the voice synthesis unit 303 generates voice information for notifying the user of the monitoring information by voice synthesis. The voice information generated by the voice synthesis is supplied to the speaker 321 of the headset 320 and provided to the user as a voice for notifying the monitoring information.

  Note that the monitoring information provided as audio information may be configured to be generated as image information by the image generation unit 305 and output to the display 322 of the headset 320 for display. By providing monitoring information with the same content as audio information in the form of an image, it is possible to notify the user of the content of the monitoring information by means of an image even if the user has missed the audio that notifies the monitoring information due to ambient noise or the like. Yes, it is possible to ensure a reliable notification of monitoring information.

  The voice information generated by voice synthesis may be, for example, simple reading of the measurement value or status that is monitoring information transmitted from the device 200b, or the voice information generation in the plant monitoring server 100 of the first embodiment. The complicated thing which the part 106 performed may be sufficient. In the case of such a configuration, the speech synthesizer 303b further includes a sentence template database. Moreover, you may comprise so that the change of the audio | voice aspect according to the importance applied in the said Embodiment 1 may be performed. In the case of such a configuration, an importance level definition database and an audio mode database are further provided.

  In step S328, when the user operates the operation unit 333 to instruct the provision of further monitoring information (step S328: NO), the portable information terminal 300b continues the processing of steps S326 to S327 again, and the device 200b responds accordingly. Then, the monitoring information is further returned (step S202). When the monitoring for the device 200b is ended (step S328: YES), the processing is ended.

  In the portable information terminal 300b, when the device identification information and the user-defined information are not transmitted (step S323: NO) and when it is determined from the user-defined information that the device is not the monitoring target device 200b (step S324: NO), The process is temporarily terminated.
