  In order to accurately grasp the state of damage to a structure, for example, it is necessary to install a plurality of sensors at different locations on the structure. Then, for example, when a large earthquake occurs, it is necessary to collect data detected by each of the plurality of sensors.

  Here, for example, an observation system in which a plurality of sensors are connected to a control device via a network can be considered. However, when power is lost or the network is disconnected due to an earthquake, it is assumed that the control device cannot collect data acquired by the sensor via the network. Therefore, such a method has a problem that the reliability of data collection is poor.

  Further, in the above-described prior art of Patent Document 1, an emergency risk degree judge has a portable terminal device, approaches an acceleration detection device (sensor) attached to a structure, and performs wireless communication to acquire data. .

  Hereinafter, the present embodiment will be described. The present embodiment described below does not unduly limit the content of the present invention described in the claims. In addition, all of the configurations described in the present embodiment are not necessarily essential components of the invention.

1. Observation System As described above, when a disaster such as an earthquake occurs, it is required to quantitatively and as quickly as possible understand the damage status of structures such as buildings. For example, if a sensor is attached to a structure, it is possible to quantitatively determine the damage state of the structure by detecting the sensing data with the sensor and analyzing the sensing data by an operator. However, when a disaster occurs, the power supply for supplying power to the sensor may be lost, or the network connecting the sensor and the data collection device may be disconnected. In this case, useful sensing data at the time of disaster occurrence may not be detected, or even if sensing data at the time of disaster occurrence may be detected, sensing data may not be obtained from the sensor. Further, even if sensing data can be obtained, it sometimes takes time to obtain the data.

  Therefore, the observation system of the present embodiment improves reliability and efficiency in collecting sensing data when an abnormal state of a structure is detected.

  Specifically, FIG. 1 shows a system configuration example of the observation system of the present embodiment. As shown in FIG. 1, the observation system 100 according to the present embodiment includes a sensor unit 110, a storage unit 120, a processing unit 130, and a battery 150 (secondary battery). The observation system 100 may further include a display unit 140 and an evacuation storage unit 160.

  The sensor unit 110 detects the state of the structure and acquires sensing data. The storage unit 120 stores at least sensing data when an abnormal state of the structure is detected. The processing unit 130 performs a transfer process of transferring monitoring information of the state of the structure obtained based on the sensing data as display information of the display unit 140. The transfer destination in the monitoring information transfer process may be the display unit 140, the evacuation storage unit 160, or both as described later. In addition, the observation system 100 is not limited to the configuration of FIG. 1 and various modifications such as omitting some of these components or adding other components are possible.

  Here, the structure refers to a building (building) such as a building or a house, or an artificial structure such as a bridge, a highway, a tower, a power pole, or a dam. Further, the structure may be a natural structure such as a mountain, a rock, a river, a tree, a river, or a cliff. Then, it is assumed that the structure is in an abnormal state when vibration or acceleration that cannot normally occur in the structure occurs. For example, the inclination of a building hardly changes throughout the day unless an abnormal condition such as an earthquake occurs. However, if an abnormal condition such as a large earthquake occurs, a building can be used for several days or months within a few hours. The inclination may change more than the inclination change. In such a case, it can be said that the structure is abnormal or the structure is in an abnormal state. Whether or not the structure is in an abnormal state can be determined based on, for example, whether or not the value indicated by the sensing data has exceeded a given threshold. More specifically, when the magnitude of the acceleration, velocity, displacement, pressure, temperature, or the like indicated by the sensing data exceeds a given threshold corresponding to each, it is determined that the structure is in an abnormal state, If these values are less than or equal to the corresponding given threshold, it is determined that the structure is not abnormal. This determination may be made by the sensor unit 110 or by the processing unit 130. Further, a system external to the observation system 100 may perform the processing.

  The sensing data is measurement data detected by the sensor unit 110. For example, when the sensor unit 110 is realized by an acceleration sensor, the sensing data is acceleration data. When the sensor unit 110 is realized by a three-axis acceleration sensor and a three-axis gyro sensor, the sensing data includes acceleration data for each of the three axes, and acceleration data for each of the three axes. This is data constituted by angular velocity data representing angular velocity. And the sensing data when the abnormal state of the structure is detected may be, for example, sensing data measured in a given period before and after the timing at which the abnormal state of the structure is detected, It may be sensing data measured in a given period after the timing when the abnormal state of the structure is detected.

  The monitoring information is generated based on the sensing data, and is information for indicating the degree of the abnormal state of the structure by a numerical value, a level, an image, a text, or the like. For example, as shown in the example of FIG. 8 described later, the monitoring information includes date and time information when a power failure occurs, date and time information when a structure is in an abnormal state, recording time information of sensing data, seismic intensity information, and structure information. The information includes amplitude information, installation location information of the sensor unit 110 (observation device MS in FIG. 2 described later), building risk information, transfer state information indicating whether or not monitoring information has been transmitted. The monitoring information may be, for example, the sensing data itself or a part of the sensing data. For example, the monitoring information is read from the storage unit 120 by the processing unit 130 and output to the display unit 140. Alternatively, after the processing unit 130 reads the monitoring information from the storage unit 120 and writes the monitoring information to the evacuation storage unit 160, the processing unit 130 reads the monitoring information from the evacuation storage unit 160 again, and May be output.

  The display information is information to be displayed on the display unit 140. The facial expression information is, for example, monitoring information output from the processing unit 130. However, the display information may be a part (or all) of the sensing data described above.

  Here, a specific example will be described with reference to FIGS. For example, in the example shown in FIG. 2, the observation system 100 of the present embodiment is realized by one observation device MS. The observation device MS houses the storage unit 120, the processing unit 130, the battery 150, and the evacuation storage unit 160 in the housing BX. The sensor unit 110 may be arranged inside the housing BX or may be attached outside the housing. Further, the display unit 140 is disposed so that the display surface can be visually recognized from outside the housing BX, that is, from the outside. For example, in the example shown in FIG. 2, the display unit 140 is an electronic paper EPP.

  In the example of FIG. 3, one observation device (MS1 to MS5) as shown in FIG. 2 is installed on each floor of the five-story building BL in order to analyze the shaking of each floor. Then, when an abnormality such as an earthquake occurs, the sensor unit 110 of each observation device (MS1 to MS5) detects sensing data at each installation location. The processing unit 130 selects sensing data for a given period before and after the timing of occurrence of abnormality as monitoring information, and causes the display unit 140 to display the monitoring information as display information. Further, the processing unit 130 causes the save storage unit 160 to store the monitoring information. After that, the worker OP goes around each of the observation devices (MS1 to MS5) and checks the display information displayed on the display unit 140. At this time, the worker reads the monitoring information stored in the evacuation storage unit 160 using the portable terminal device IT carried by the worker.

  As described above, since the display information is displayed on the display unit 140, the worker OP can quantitatively judge at a glance the damage situation at the installation location of the sensor unit 110 (observation devices MS1 to MS5). . Further, as described above, for example, by displaying the transfer state information of the monitoring information on the display unit 140, the operator can quickly distinguish the observation device to which the data has been transferred from the observation device to which the data has not been transferred. As a result, the efficiency of data collection can be improved.

  Further, in the present embodiment, it is possible to obtain monitoring information even when the network is disconnected. For example, since the monitoring information (sensing data) is stored in the evacuation storage unit 160, the reliability of data acquisition can be improved.

  Therefore, it is possible to improve reliability and efficiency in collecting sensing data when an abnormal state of a structure is detected.

  Further, as described above, when power supply to the sensor unit 110 and the processing unit 130 is stopped due to a disaster such as an earthquake, the sensor unit 110 cannot detect sensing data, and the processing unit 130 Information cannot be transferred to the save storage unit 160.

  Therefore, the observation system 100 illustrated in FIG. 1 includes the battery 150, and the processing unit 130 operates based on the power from the battery 150. Accordingly, even when the supply of power from the outside is stopped due to the occurrence of an earthquake or the like, the processing unit 130 can be operated until the remaining power of the battery 150 is exhausted. The same applies to the sensor unit 110.

  The processing unit 130 performs at least one of a process of transferring the monitoring information to the display unit 140 and a process of transferring the monitoring information to the evacuation storage unit 160 as the above-described transfer process. For example, when the supply of power is stopped, if such a monitoring information transfer process is performed before the remaining power of the battery 150 runs out, the monitoring information can be transmitted even after the remaining power of the battery 150 runs out. Can be read out from the evacuation storage unit 160 or confirmed by the display on the display unit 140. That is, for example, even when the supply of power from the power supply is stopped, for example, when the power supply is lost, it is possible to reliably and efficiently collect the sensing data when the abnormal state of the structure is detected.

2. Detailed Configuration Example of Observation System Next, FIG. 4 shows a detailed configuration example of the observation system 100 (monitoring system) of the present embodiment. As shown in FIG. 4, the observation system 100 of the present embodiment includes a sensor unit 110, a storage unit 120 (volatile memory), a processing unit 130 (processor), a display unit 140, and a battery 150 (secondary battery). ), A power supply circuit 170, and an IC tag chip 190. The IC tag chip 190 includes a save storage unit 160 (non-volatile memory). Observation system 100 is not limited to the configuration shown in FIG. 4, and various modifications can be made such as omitting some of these components or adding other components.

  Next, each unit of the observation system 100 will be described.

  The sensor unit 110 detects the state of the structure and acquires sensing data. The sensor unit 110 is realized by, for example, a six-axis sensor including a three-axis acceleration sensor and a three-axis gyro sensor, as described above. However, the present embodiment is not limited thereto, and the sensor unit 110 may be an acceleration sensor or a gyro sensor. In addition, the sensor unit 110 may be an inclination sensor that detects the inclination of the structure, a vibration sensor that detects the vibration of the structure, a temperature sensor that detects a temperature change of the structure, or the like.

  The storage unit 120 stores at least sensing data when an abnormal state of the structure is detected. The storage unit 120 is implemented by a volatile memory such as a RAM (Random Access Memory) to which data can be electrically written, and is used as a work area in the processing unit 130.

  The processing unit 130 performs a transfer process of transferring monitoring information of the state of the structure obtained based on the sensing data as display information of the display unit 140. The transfer process may be a process of outputting the monitoring information to the display unit 140 or the evacuation storage unit 160, or a process of transmitting the monitoring information to the display unit 140 or the evacuation storage unit 160 via a network. Is also good. The function of the processing unit 130 is realized by a processor such as a CPU (Central Processing Unit). The processor is not limited to the CPU, and various processors such as a GPU (Graphics Processing Unit) or a DSP (Digital Signal Processor) can be used. Further, the processor may be a hardware circuit based on an ASIC (Application Specific Integrated Circuit).

  The display unit 140 is a display unit that can display display information even when power is not supplied. Strictly speaking, the display unit 140 is a display unit that can continuously display display information even during a period in which power is not supplied. For example, the display unit 140 is realized by an electrophoretic display such as electronic paper. Electronic paper has a feature in that power is consumed when information is rewritten, but power is not consumed or power consumption is minimal when information is displayed. Another feature is that power consumption at the time of rewriting display information is small. Therefore, the electronic paper is particularly useful in a case where there is a high possibility that the power is not supplied when the need to confirm the display information is high, as in the case of using the observation system of the present application. Note that an electrophoretic display is a display portion that employs an electrophoretic method. In the electrophoresis method, for example, white and black are displayed by moving particles by an electric field in a microcapsule containing a fluid of white and black particles.

  This makes it possible to continuously display display information without consuming power or greatly reducing power consumption. For example, even when the supply of power from the power supply 300 is stopped due to the occurrence of a disaster or the like, it is possible to suppress the power consumption and continue to display the display information. Therefore, even after a long time elapses after the power supply from the power supply 300 is stopped, it is possible for the worker to check the display information and the like. However, the display unit 140 of the present embodiment is not limited to the above example. For example, the display unit 140 may be a display panel on which characters or symbols are physically described or a picture is drawn. good. In this case, for example, the processing unit 130 performs control to move a display panel having contents corresponding to the damage state of the structure to a position that can be visually observed from the outside, and notifies the worker of the damage state of the structure.

  When the IC tag chip 190 (RF tag) receives a data read command transmitted from the external portable terminal device 500 by short-range wireless communication, the IC tag chip 190 (RF tag) transmits the monitoring information stored in the evacuation storage unit 160 to the external portable terminal. The information is transmitted to the device 500 or the like. The IC tag chip 190 is realized by, for example, a passive type IC tag chip that operates by receiving power from a radio signal transmitted from the external portable terminal device 500. The IC tag chip 190 is a so-called RFID (Radio Frequency IDentifier), and includes, for example, an evacuation storage unit 160, a transmission / reception unit (antenna unit) not shown, and a control unit not shown. As a communication standard for short-range wireless communication, Bluetooth (registered trademark) or the like can be used, but the present embodiment is not limited to this.

  The evacuation storage unit 160 is a nonvolatile memory in which data can be electrically written, and stores monitoring information and the like output from the processing unit 130. For example, the save storage unit 160 is realized by an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), a flash memory, or the like.

  The battery 150 (secondary battery) supplies power to the processing unit 130 and the like via the power supply circuit 170. The battery 150 is charged via the power supply circuit 170 based on the power supplied from the power supply 300.

  For example, when power is supplied from the power supply 300, the power supply circuit 170 performs at least a power supply operation to the sensor unit 110 and the processing unit 130 and a power supply operation to the battery 150 based on the supplied power. Do one. When power is supplied from the power supply circuit 170 to the battery 150, the battery 150 is charged. In addition, the power supply circuit 170 may perform an operation of switching between an operation of supplying power to the sensor unit 110 and the processing unit 130 and an operation of supplying power to the battery 150. Then, for example, when the supply of power from the power supply 300 is stopped, the power supply circuit 170 performs a discharging operation of the battery 150 and supplies the power discharged from the battery 150 to the sensor unit 110, the processing unit 130, and the like. When the power from the power supply 300 is not directly supplied to the sensor unit 110, the processing unit 130, and the like, the power supply circuit 170 supplies the power from the power supply 300 to the battery 150 once, and then stores the power in the battery 150. The power is discharged to supply power to the sensor unit 110, the processing unit 130, and the like. The power supply 300 is, for example, an AC power supply.

3. Next, the details of the processing of this embodiment will be described with reference to the flowchart of FIG.

  First, the processing unit 130 has a timer, and performs an intermittent operation using the timer (S101). The processing unit 130 determines whether or not it is an operation timing using a timer (S101). Is determined (S102). When determining that the power supply from the main power supply has not been stopped, the processing unit 130 continuously determines whether the remaining power of the battery 150 is equal to or less than a given set value (S103). Then, when the processing unit 130 determines that the remaining power of the battery 150 is larger than the given set value, the processing unit 130 acquires sensing data from the sensor (the sensor unit 110) (S104). Note that the sensor unit 110 is assumed to be operating at all times while power is being supplied from the power supply 300 or the battery 150. Then, the processing unit 130 performs a process of storing the acquired sensing data in the main body memory (the storage unit 120) (S105), and returns to step S101. Note that the storage unit 120 overwrites newly acquired data with the most recently acquired data.

  On the other hand, when the processing unit 130 determines that the supply of power from the main power supply is stopped (S102), or when the supply of power from the main power supply is not stopped, the remaining power of the battery 150 is low. If it is determined that the given value is equal to or less than the set value, power may not be supplied to the processing unit 130, and the acquired data may not be transferred to the evacuation storage unit 160 or the display unit 140. Therefore, in this case, the processing unit 130 generates monitoring information based on the sensing data stored in the main body memory (the storage unit 120) (S106), and transfers the generated monitoring information to the evacuation storage unit 160. Processing is performed (S107). Further, the processing unit 130 also transfers the monitoring information to the display unit 140 as display information, and displays the display information acquired by the display unit 140 (S107).

  As described above, when the processing unit 130 determines that the remaining power of the battery 150 is equal to or less than the given set value, the processing unit 130 transfers the monitoring information to the display unit 140 and sends the monitoring information to the save storage unit 160. At least one of the transfer processes.

  This makes it possible to transfer monitoring information to at least one of the display unit 140 and the evacuation storage unit 160 before the remaining power of the battery 150 is exhausted. Therefore, even after the remaining power of the battery 150 is exhausted, for example, the worker can read the monitoring information from the evacuation storage unit 160 using the portable terminal device 500 or display the display information on the display unit 140 that is an electronic paper. It is possible to grasp the damage state of the structure by confirming the condition.

  In steps S106 to S107 in FIG. 5, the processing unit 130 performs a transfer process of transferring selected sensing data selected from the sensing data stored in the storage unit 120 as monitoring information.

  A specific processing flow in this case will be described with reference to FIG. The processing in steps S201 to S205 in FIG. 6 corresponds to the processing in steps S106 to S107 in FIG.

  For example, the processing unit 130 checks the remaining memory capacity of the evacuation storage unit 160 (S201). The remaining memory capacity of the evacuation storage unit 160 refers to the usable storage capacity of the evacuation storage unit 160, for example, the amount of data that can be newly stored in the evacuation storage unit 160. Then, the processing unit 130 determines whether or not the data amount of the sensing data stored in the main body memory (the storage unit 120) is larger than the remaining memory of the evacuation storage unit 160 (S202).

  Next, when the processing unit 130 determines that the data amount of the sensing data stored in the main body memory (the storage unit 120) is larger than the remaining memory capacity of the evacuation storage unit 160, the processing unit 130 Then, a range (hereinafter, referred to as a selection range) of the sensing data to be transferred is specified (S203). Then, the processing unit 130 generates sensing data corresponding to the selected range (hereinafter, referred to as selected sensing data) as monitoring information (S204), and transfers the generated monitoring information to the evacuation storage unit 160 (S205). .

  More specifically, if the data amount of the sensing data stored in the storage unit 120 is larger than the available storage capacity of the evacuation storage unit 160, the processing unit 130 From among them, the selected sensing data having a given data amount equal to or less than the available storage capacity is specified, and the specified selected sensing data is transferred.

  For example, at this time, the processing unit 130 specifies, as the selected sensing data, the sensing data acquired during a predetermined period before and after the timing at which the structure enters the abnormal state, for example, and transfers the selected sensing data. Thus, for example, the worker can read the sensing data itself during the period that the worker most wants to check, such as the timing when the structure becomes abnormal, using the portable terminal device 500 or the like.

  On the other hand, when the processing unit 130 determines that the data amount of the sensing data stored in the main body memory is equal to or less than the remaining memory amount of the evacuation storage unit 160, the processing unit 130 stores all the data stored in the evacuation storage unit 160. The sensing data is transferred to the evacuation storage unit 160 as monitoring information (S205). In this case, the worker can check not only the timing at which the structure has become abnormal, but also the sensing data at other timings, for example.

  That is, the processing unit 130 determines the selection range of the selected sensing data, which is the monitoring information, based on the available storage capacity of the evacuation storage unit 160, and transfers the selected selection sensing data to the evacuation storage unit 160. Perform transfer processing. Specifically, as described above, if all of the sensing data stored in the main body memory can be stored in the evacuation storage unit 160 due to the storage capacity of the evacuation storage unit 160, The sensing data is transferred from the main body memory to the evacuation storage unit 160; otherwise, only a part of the sensing data stored in the main body memory is transferred to the evacuation storage unit 160.

  This makes it possible to transfer the sensing data of the amount of data that can be stored in the evacuation storage unit 160 from the storage unit 120 to the evacuation storage unit 160. As a result, an operator can confirm a sufficient amount of sensing data in order to analyze the damage state of the structure.

  Further, in addition to the example of FIG. 6 described above, the processing unit 130 includes an operable time of the processing unit 130 based on the power of the battery 150 and a time required to transfer the sensing data to the display unit 140 or the evacuation storage unit 160. The selection range of the selected sensing data may be determined based on at least one of the above.

  In this case, the processing unit 130 specifies the selection range corresponding to the data amount in which the required transfer time is shorter than the operable time, and performs the transfer processing of the selected sensing data corresponding to the specified selection range.

  FIG. 7 shows a specific processing flow in this case. In the example of FIG. 7, steps S301 to S304 are the same as steps S101 to S105 of FIG.

  When detecting the stop of the power supply from the main power supply, or when determining that the remaining power of the battery 150 is equal to or less than the given set value even when the power supply is not stopped, 6, the remaining amount of memory in the evacuation storage unit 160 is confirmed (S306). Then, similarly to steps S202 to S204 in FIG. 6, the processing unit 130 determines the selection range and specifies the selected sensing data (S307). That is, the processing unit 130 specifies the selected sensing data from the sensing data stored in the storage unit 120 based on the available storage capacity of the evacuation storage unit 160.

  Next, the processing unit 130 specifies the operable time of the processing unit 130 based on the remaining power of the battery 150 (S308), and displays the sensing data display unit 140 based on the selected sensing data specified in step S307. Alternatively, the time required for transfer to the save storage unit 160 is specified (S308).

  Then, the processing unit 130 determines whether or not the required transfer time is longer than the operable time (S310). If it determines that the required transfer time is longer than the operable time, the processing unit 130 changes the selection range of the sensing data. Reduction is performed (S311), and the selected sensing data corresponding to the reduced selection range is specified (S312). For example, when it is determined that the operable time of the processing unit 130 calculated from the remaining power of the battery 150 is 2 minutes and the transfer time of the selected sensing data specified in step S307 is 4 minutes, the selected sensing is performed. The data is reduced to a size that can be transmitted within two minutes. Next, the processing unit 130 transfers the reduced selected sensing data specified in step S312 from the main body memory (storage unit 120) to the evacuation storage unit 160 as monitoring information (S313). Further, the processing unit 130 transfers the monitoring information as the display information to the display unit 140, and the display unit 140 displays the display information (S314).

  On the other hand, if the processing unit 130 determines that the required transfer time is equal to or longer than the operable time, the processing unit 130 transmits the selected sensing data corresponding to the selection range determined in step S307 from the main memory to the evacuation storage unit 160 and the display unit. The data is transferred to the display unit 140 (S313) and displayed on the display unit 140 (S314).

  This makes it possible to specify the selected sensing data having a data amount suitable for the operable time of the processing unit 130 or the data transfer required time.

  This makes it possible to transfer all of the selected sensing data, which is monitoring information, from the storage unit 120 to at least one of the evacuation storage unit 160 and the display unit 140 before the remaining power of the battery 150 is exhausted. Become. Therefore, even if the sensor unit 110 detects the sensing data when the structure is in the abnormal state, the case where the sensing data at that time is not stored in the evacuation storage unit 160 or the like is prevented. be able to. Therefore, the worker can more surely check the monitoring information when the structure is in the abnormal state.

  Further, the monitoring information is not limited to only the selected sensing data described above, and is obtained based on, for example, acquisition status information of the sensing data, state determination information of the structure obtained based on the sensing data, and the sensing data. It may include at least one of disaster status information and transfer status information of sensing data.

  The acquisition status information of the sensing data is information indicating the acquisition status of the sensing data. For example, the acquisition status information includes information indicating whether or not sensing data has been acquired in a given period before and after the timing when the structure enters an abnormal state, and information before and after the timing when power supply from the power supply 300 is stopped. Is information indicating whether sensing data has been acquired in a given period of time. Then, for example, the processing unit 130 specifies information such as images and characters indicating the success or failure of sensing data acquisition, screen color (color), light emission pattern, sound output pattern, and the like as acquisition status information. For example, in the display example DI1 of the display unit 140 illustrated in FIG. 8, when the acquisition status information is character information, the processing unit 130 determines the date and time of acquisition of the sensing data (in D1 of FIG. 10:00 ”) and the recording period of the sensing data (“ 5 minutes ”in D1 of FIG. 8) are specified as acquisition status information and displayed on the display unit 140. Further, in the example of FIG. 2 described above, the processing unit 130 obtains, as the acquisition status information, character information “storage data: available” and “data storage period: 2015/01/01 0:00:00 to 2015/01/01”. The character information “02 1:00” is specified and displayed on the display unit 140.

  In addition, when the observation system 100 further includes a light emitting unit (not shown), if sensing data in a given period can be normally acquired, the light emitting unit emits light in green, for example, and the given period In the case where the sensing data in has not been acquired normally, the light emitting unit may emit red light, for example. In this case, the acquisition status information is instruction information (light emission pattern information) as to whether the light emitting unit emits green light or red light. In addition, as shown in a display example DI2, information indicating a place where the sensor unit 110 is installed (in the display example DI2, “20 floors of building” is specified as acquisition status information of sensing data, It may be displayed.

  Next, the structure state determination information is, for example, information indicating the state of the structure specified based on the sensing data. For example, the state determination information is information indicating how much the structure has been damaged as a result of the structure being in an abnormal state, or information indicating whether there is a risk of damage. For example, in the display example DI3 of FIG. 8, character information indicating that the building risk is high is displayed on the display unit 140 as the state determination information.

  In the display examples DI4 and DI5 in FIG. 8, the degree of collapse risk of the structure is represented by the color of the screen. For example, in the display example DI4, the display screen of the display unit 140 emits light in yellow (indicated by oblique lines in FIG. 8) to notify the worker of a medium danger. Further, in the display example DI5, the display screen of the display unit 140 emits red light (shown in gray in FIG. 8) to notify the worker that the risk is high. In this case, the state determination information is the color information of the display screen, the processing unit 130 transmits the color information of the display screen to the display unit 140, and changes the color of the display screen according to the color information acquired by the display unit 140. .

  The disaster status information is information indicating the status of a disaster presumed to have occurred when the structure was in an abnormal state. For example, when the structure shakes more than usual and becomes abnormal, it is estimated that an earthquake has occurred. In this case, the processing unit 130, for example, as shown in display examples DI2 and DI3 in FIG. 8, the seismic intensity of the earthquake (“lower 5” in display example DI2) and the maximum amplitude (“1 m” in display example DI2). ), The maximum acceleration (“xxx (cm / s ＾ 2)” in the display example DI3), the maximum speed (“xxx (cm / s)” in the display example DI3), the presence or absence of a long-period ground motion, and the like. The information is displayed on the display unit 140.

  Further, the transfer state information includes, for example, characters and images indicating that monitoring information has been transferred from the observation system 100 to the portable terminal device 500 held by the worker, screen colors (colors), light emission patterns, and sound output patterns. , Vibration patterns and the like. For example, in the display example DI6 of FIG. 8, the transfer state information is character information of “sent stored data”. In addition, when the transfer status information is information relating to the screen color and the monitoring information has not been transferred, the processing unit 130 changes the display screen of the display unit 140 to a green screen and changes the monitoring information. When the transfer is completed, the display screen of the display unit 140 may be changed to a monochrome screen. In this case, after the transfer of the monitoring information, the processing unit 130 changes the transfer state information from the information indicating the untransferred state to the information indicating the transferred state. For example, in the example described above, the information indicating the untransferred state is information instructing that the display screen of the display unit 140 be changed to a green screen, and the information indicating the transferred state is changed to a monochrome screen. This is the information to be instructed. In other words, it can be said that the processing unit 130 changes the display mode of the display screen of the display unit 140 after the transfer of the monitoring information.

  Thereby, the processing unit 130 transfers at least one of the acquisition status information of the sensing data, the state determination information of the structure, the disaster status information, and the transfer status information to the evacuation storage unit 160, the display unit 140 And so on. Then, the worker can read these pieces of information from the evacuation storage unit 160 using the portable terminal device 500, and the worker can check these pieces of information displayed on the display unit 140. In addition, if such information is displayed on the display unit 140, even if the worker does not carry the portable terminal device 500 capable of reading data, the worker can be given an overview of the damage status of the structure. Can tell.

  In addition, if the transfer state information of the monitoring information is displayed on the display unit 140 among the above information, it is quickly determined from which observation system 100 the operator has read the monitoring information using the portable terminal device 500. And so on. Therefore, it is possible to prevent a worker from losing sight of which observation system 100 has read the monitoring information, and to reduce the trouble of reading the monitoring information again from the observation system 100 after reading the monitoring information. As a result, the efficiency of collecting monitoring information from the plurality of observation systems 100 can be improved.

  In addition, among the above information, the acquisition status information, the status determination information, and the disaster status information are not displayed on the display unit 140 of the observation system 100, but can be transmitted from the worker's portable terminal device 500 or the portable terminal device 500. Can be confirmed and analyzed by a PC or the like to which the data has been transferred. Such information does not necessarily need to be confirmed on site. Rather, if too much information is displayed on the display unit 140 of the observation system 100, there is a problem that the screen becomes hard to see. On the other hand, among the above information, the transfer state information of the monitoring information is significant for the worker to confirm on site for the above-described reason.

  Therefore, the processing unit 130 may hide the acquisition status information, the status determination information, the disaster status information, and the transfer status information on the display unit 140 and display the transfer status information of the monitoring information.

  This makes it possible to easily display the transfer state information of the monitoring information on the display screen of the display unit 140.

4. Modification Example Next, a first modification example of the present embodiment will be described. In the first modified example, as shown in FIG. 9, the observation system 100 includes a sensor unit 110, a storage unit 120 (nonvolatile memory), a processing unit 130 (processor), and a display unit 140 (electronic paper). , A battery 150 (secondary battery), a power supply circuit 170, and an IF unit 90. 4 in that the IC tag chip 190 is not included and the IF unit 90 is included.

  Further, unlike the example of FIG. 4, the storage unit 120 in the example of FIG. 9 is a nonvolatile memory to which data can be electrically written. In this case, the storage unit 120 plays the role of the evacuation storage unit 160 in FIG. 4, and there is no need to provide the evacuation storage unit 160 separately. That is, the storage unit 120 stores sensing data obtained from the sensor unit 110 and monitoring information obtained from the processing unit 130.

  The IF unit 90 (interface unit) is, for example, a USB port or a USB terminal.

  In this modification, the portable terminal device 500 of the worker is connected to the observation system 100 via the IF 90 for communication, and the processing unit 130 transmits monitoring information and the like stored in the storage unit 120 to the portable terminal device 500. Send.

  Accordingly, even if the observation system 100 does not have the IC tag chip 190, the worker can read the monitoring information using the portable terminal device 500, and the like. Note that the other points are the same as those in the example of FIG.

  Next, a second modification of the present embodiment will be described. In the second modified example, as shown in FIG. 10, the observation system 100 includes a sensor unit 110, a storage unit 120 (volatile memory), a processing unit 130 (processor), and a display unit 140 (electronic paper). , A battery 150 (secondary battery), a power supply circuit 170, an IC tag chip 190, and a wireless power receiving unit 210. 4 in that the wireless power receiving unit 210 is included. Other points are the same as those in the example of FIG.

  In the example of FIG. 4 described above, the power transmitted from the AC power supply 300 is supplied to the processing unit 130 and the like via the power supply circuit 170, and the processing unit 130 operates based on the power from the AC power supply 300. Was.

  On the other hand, in the present modified example, the wireless power receiving unit 210 receives power transmitted from the external wireless power transmitting unit 220 by contactless power transmission. Then, the wireless power receiving unit 210 supplies the received power to the power supply circuit 170, and the power supply circuit 170 supplies power to the sensor unit 110, the processing unit 130, and the like. The processing unit 130 operates with electric power by non-contact power transmission, and performs a transfer process of transferring monitoring information of the state of the structure obtained based on the sensing data.

  The power transmission from the wireless power transmission unit 220 to the wireless power reception unit 210 electromagnetically couples a primary coil (power transmission coil) L1 of the wireless power transmission unit 220 and a secondary coil (power reception coil) L2 of the wireless power reception unit 210. This is realized by forming a power transmission transformer.

  The wireless power transmission unit 220 includes a primary coil L1 (not shown), a first power transmission driver DR1 driving one end of the primary coil, a second power transmission driver DR2 driving the other end of the primary coil L1, It includes a power supply voltage control unit that controls the power supply voltage VDRV of the drivers DR1 and DR2, and a driver control circuit. Each of the power transmission drivers DR1 and DR2 is realized by, for example, an inverter circuit (buffer circuit) including a power MOS transistor. Then, for example, the driver control circuit outputs a control signal (drive signal) to the gates of the transistors constituting the power transmission drivers DR1 and DR2, and drives the primary coil L1 by the power transmission drivers DR1 and DR2.

  The wireless power receiving unit 210 includes, for example, a secondary coil L2 (not shown) and a rectifier circuit. The rectifier circuit includes a plurality of transistors and diodes, and converts an AC induced voltage of the secondary coil L2 into a DC rectified voltage VCC and outputs the DC rectified voltage to the power supply circuit 170.

  This enables non-contact power transmission. Various methods such as an electromagnetic induction method or a magnetic field resonance method can be adopted as a method of non-contact power transmission.

  Further, in the example of FIG. 4 described above, the power cable or the like connecting the AC power supply 300 and the power supply circuit 170 may be disconnected due to the occurrence of a disaster or the like. When power is received by power transmission, power supply does not stop due to disconnection of a power cable.

  This makes it possible to reduce the possibility that the power supply to the observation system 100 is stopped even if a disaster or the like occurs. That is, even if a disaster or the like occurs, it is possible to more stably receive power supply and the like. As a result, it becomes possible to acquire sensing data for a long period of time when the structure becomes abnormal due to a disaster, etc., and it is possible to further improve the analysis accuracy of the damage situation of the structure, etc. Will be possible.

  Further, the wireless power receiving unit 210 can include a load modulation unit (not shown) that performs communication with the wireless power transmitting unit 220 by load modulation. In this case, the load modulation unit can perform load modulation and transmit monitoring information to the wireless power transmission unit 220. In this case, the IC tag chip 190 does not necessarily need to be provided, and for example, a nonvolatile memory may be used for the storage unit 120 as in the example of FIG. 9 described above.

  Next, a third modification of the present embodiment will be described. In the third modification, as shown in FIG. 11, the observation system 100 (control device) includes a storage unit 120 (volatile memory), a processing unit 130 (processor), a display unit 140 (monitor), and a battery. 150 (secondary battery), an evacuation storage unit 160 (nonvolatile memory), and a power supply circuit 170. In this modification, n sensor units (110-1 to 110-n) (n is an integer of 2 or more) are connected to the processing unit 130, and the power supply circuit 170 is connected to the n sensor units. (110-1 to 110-n).

  Then, the processing unit 130 performs a process of detecting the state of the structure and receiving the sensing data from the sensor units (110-1 to 110-n) that acquire the sensing data.

  That is, in the third modification, as in the example shown in FIG. 12, the control device MS that is the observation system 100 is connected to the plurality of sensor units (SE1 to SE5), and the plurality of sensor units (SE1 to SE5). The control device MS collectively manages the sensing data acquired in SE5). For example, in the example of FIG. 12, as in the example of FIG. 3 described above, one sensor unit is installed on each floor of a five-story building, and one control device MS is installed outside the building. Have been. The plurality of sensor units (SE1 to SE5) and the control device MS are connected by a network. Further, the power supply circuit 170 and each of the plurality of sensor units (SE1 to SE5) are connected by a power cord or the like.

  In this case, the display unit 140 is realized by, for example, a liquid crystal display instead of electronic paper, and the evacuation storage unit 160 is realized by a hard disk drive or the like.

  This eliminates the need for the worker to go around the installation location of each sensor unit and acquire monitoring information. That is, according to the present modification, all the monitoring information that is connected to the control device having the evacuation storage unit, is normally detected, and is normally transferred can be acquired from the control device. As a result, the collection efficiency of the monitoring information can be improved.

  Note that the observation system or the like of the present embodiment may implement a part or most of the processing by a program. In this case, the processor such as the CPU executes the program, thereby realizing the observation system and the like of the present embodiment. Specifically, a program stored in the non-temporary information storage device is read, and a processor such as a CPU executes the read program.

(Memory, ROM, etc.). Then, a processor such as a CPU performs various processes of the present embodiment based on a program (data) stored in the information storage device. That is, the information storage device has a program for causing a computer (a device including an operation unit, a processing unit, a storage unit, and an output unit) to function as each unit of the present embodiment (a program for causing a computer to execute processing of each unit) Is stored.

  Further, the observation system or the like of the present embodiment may include a processor and a memory. The processor here may be, for example, a CPU (Central Processing Unit). However, the processor is not limited to the CPU, and various processors such as a GPU (Graphics Processing Unit) or a DSP (Digital Signal Processor) can be used.
