Japanese Patent No. 4824277

  The technique described in Patent Literature 1 is based on the premise that a series of processes for transmitting a transmission telegram can be completed using energy stored in the energy storage unit. It is desirable to execute appropriate processing considering the stored energy beyond the technique described in Patent Document 1.

  This invention was made in order to solve the above-mentioned subject, and the object is a sensor which can perform suitable processing in consideration of stored energy in the composition which operates using the electric power from an electrical storage part. An information transmission device, a sensor information transmission system, and a sensor information reception device are provided.

  (1) In order to solve the above-described problem, a sensor information transmission device according to an aspect of the present invention operates using electric power from a power storage unit, and processes a sensor information acquired from the sensor. A transmitter that operates using electric power from the power storage unit and transmits the sensor information processed by the sensor information processing unit to another device, and the sensor information processing unit performs processing of the sensor information. In the state of being performed, if the interruption condition is satisfied, the processing of the sensor information is interrupted, and the interruption information is the sensor information processing unit at the timing at which the interruption condition is satisfied and the processing of the sensor information is interrupted. Is set so that the power storage unit has a remaining amount of power that can continue the processing of the sensor information.

  In this way, the energy storage unit is configured not to continuously use the stored energy of the power storage unit until the processing of the sensor information is completed, but to interrupt the processing of the sensor information while leaving the stored energy of the power storage unit to some extent. The time until the next charging is completed can be shortened, and the start or restart of the processing of the sensor information can be accelerated. Thereby, it is possible to shorten the waiting time from the completion of processing of certain sensor information to the start of processing of new sensor information. Specifically, for example, the overall processing speed of each piece of sensor information acquired sequentially can be improved, so that the sensor sample interval can be shortened, and the accuracy of measurement using the sensor can be improved. Can do. Furthermore, it is possible to reduce the processing time of sensor information such that the processing is not completed with one power storage amount in the power storage unit. Therefore, in a configuration that operates using power from the power storage unit, it is possible to execute appropriate processing in consideration of stored energy.

Accordingly, it is possible to appropriately select whether or not to suspend and resume sensor information processing.

When the predetermined restart condition is satisfied, the processing of the sensor information is restarted.

  In this way, by setting the restart condition, the sensor information processing in the sensor information processing unit can be restarted when sufficient power is prepared.

  (5) More preferably, the sensor information processing unit adjusts the restart condition according to the remaining amount of processing of the interrupted sensor information.

  With this configuration, in addition to shortening the waiting time from the completion of processing of certain sensor information to the start of processing of new sensor information, when the remaining amount of processing of interrupted sensor information is small It is possible to accelerate the resumption of the processing of the sensor information and shorten the time until the processing of the sensor information is completed.

  (6) Preferably, the sensor information processing unit satisfies the interruption condition when a remaining power storage amount of the power storage unit is less than a predetermined threshold value or an output voltage of the power storage unit is lower than a predetermined threshold value. Judge that

  With such a configuration, the interruption process of the sensor information can be performed at an appropriate timing according to the state of the power storage unit. That is, the sensor information processing can be interrupted at an appropriate timing reflecting the remaining amount of power stored in the power storage unit or the output voltage.

  (7) Preferably, the sensor information processing unit determines that the interruption condition is satisfied when a predetermined time elapses after the processing of the sensor information is started.

  Thus, with a simple configuration for measuring the predetermined time, it is possible to set the timing for interrupting the sensor information and to interrupt the processing of the sensor information at a timing desired by the user, for example.

  (8) Preferably, the sensor information processing unit includes a processor, and the sensor information processing unit counts the number of processing cycles executed by the processor after the processing of the sensor information is started. When the value reaches a predetermined value, it is determined that the interruption condition is satisfied.

  With such a configuration, it is possible to interrupt the processing of the sensor information at an appropriate timing according to the processing time of the processor in the sensor information processing unit.

  (9) Preferably, the sensor information processing unit interrupts processing of the sensor information based on the interrupt condition according to the type of the acquired sensor information or the type of the sensor corresponding to the acquired sensor information. , Whether or not to perform.

  With such a configuration, it is possible to appropriately select whether to suspend and resume sensor information processing according to the type of sensor information or the type of sensor. The time until sensor information processing is completed can be shortened.

  The sensor information processing unit 14 includes, for example, a processor such as a CPU (Central Processing Unit) or an MPU (Micro-Processing Unit), and performs various arithmetic processes. Here, the processor includes an arithmetic unit, registers for storing various information such as instructions and addresses, and peripheral circuits.

  More specifically, the sensor information processing unit 14 operates using the electric power from the power storage unit 12, and performs various calculations and format conversion processes (hereinafter collectively referred to as calculation processes) on the sensor information acquired from the sensor 151. Also referred to as). Then, the sensor information processing unit 14 performs output processing for outputting the processed sensor information to the wireless transmission unit 18.

  The sensor information processing unit 14 may be configured to perform only the output process, that is, the process of outputting the sensor information as it is to the wireless transmission unit 18 without performing the calculation process on the sensor information. The data length of the sensor information output from the sensor information processing unit 14 to the wireless transmission unit 18 may be a fixed length or a variable length.

  In addition, the sensor information processing unit 14 reads data and the like used for arithmetic processing from the main memory 17 and writes data and the like indicating the result of the arithmetic processing in the main memory 17. The sensor information processing unit 14 may incorporate the main memory 17. The sensor information processing unit 14 may incorporate a cache memory and use the cache memory in addition to the main memory 17 for arithmetic processing.

  The sensor information processing unit 14 can use the timer 15 and sets a value in the timer 15. The timer 15 operates according to the set value of the sensor information processing unit 14 and notifies the sensor information processing unit 14 when it expires. The timer 15 may be a software timer such as a system timer provided in an OS (Operating System) used by the processor of the sensor information processing unit 14, or a hardware timer using a crystal resonator or the like. Also good.

  The nonvolatile memory 16 is, for example, a flash memory, and stores data written by the sensor information processing unit 14 in a nonvolatile manner. Note that the nonvolatile memory 16 may be built in a processor in the sensor information processing unit 14.

  The wireless transmission unit 18 operates using the power from the power storage unit 12 and transmits the sensor information processed by the sensor information processing unit 14 to another device. More specifically, the wireless transmission unit 18 converts the sensor information received from the sensor information processing unit 14 into an analog signal, converts it into a wireless signal, and transmits it to the sensor information reception device 201 via the antenna 19. The sensor information transmission apparatus 101 may be configured to include a wired transmission unit that transmits sensor information to the sensor information reception apparatus 201 by wire instead of the wireless transmission unit 18.

  FIG. 3 is a diagram showing a configuration of a sensor information receiving apparatus in the sensor information transmission system according to the embodiment of the present invention.

  With reference to FIG. 3, the sensor information receiving apparatus 201 includes an antenna 21, a wireless receiving unit 22, a sensor information processing unit 23, and a storage unit 24.

  The wireless reception unit 22 receives the wireless signal transmitted from the sensor information transmission apparatus 101 via the antenna 21, converts it into a digital signal, and outputs it to the sensor information processing unit 23.

The sensor information processing unit 23 may display the processing result on a display unit (not shown).

  FIG. 4 is a diagram showing a comparative example of a change in the remaining amount of electricity stored in the sensor information transmission device according to the embodiment of the present invention.

  Referring to FIG. 4, in this comparative example, first, charging of power storage unit 12 is started (timing t0), and the remaining power storage of power storage unit 12 rises from P11 by the power generation operation of power generation unit 11, Reach P1. Here, P1 is an amount necessary to complete, for example, the calculation processing and output processing of one sensor information. P11 is a value close to zero, for example. And the sensor information processing part 14 starts the calculation process and output process of sensor information (timing t1).

  Then, the remaining amount of power stored in the power storage unit 12 decreases with the execution of the sensor information calculation process and output process, and the sensor information calculation process and output process is completed. P11 is reached (timing t2).

  Then, the remaining amount of power stored in the power storage unit 12 rises again from P11 due to the power generation operation of the power generation unit 11, and when it reaches P1 again, the sensor information processing unit 14 performs a new sensor information calculation process and output process. Start (timing t3).

  In this comparative example, all the energy stored in the power storage unit 12 is used in one process of sensor information, and the amount of energy to be recharged increases. For this reason, the waiting time from the completion of processing of certain sensor information to the start of processing of new sensor information, specifically, the time from timing t2 to t3, becomes long.

  Therefore, the sensor information transmission apparatus according to the embodiment of the present invention solves the above problems by executing appropriate processing in consideration of the stored energy of the power storage unit 12 with the following configuration and operation.

[Operation]
Next, the operation when the sensor information transmission apparatus according to the embodiment of the present invention transmits sensor information will be described with reference to the drawings.

  FIG. 5 is a diagram showing an overview of the interruption process and the resumption process in the sensor information transmission apparatus according to the embodiment of the present invention.

  Referring to FIG. 5, if the sensor information processing unit 14 satisfies the interruption condition in the state of processing the sensor information, the sensor information processing unit 14 stores the processing information being used in the processing of the sensor information in the nonvolatile memory 16. Suspend sensor information processing. This interruption condition is a predetermined condition in consideration of, for example, the remaining amount of electricity stored in the power storage unit 12 or the amount of energy stored in the power storage unit 12. In addition, the interruption condition is such that the storage unit 12 has a remaining amount of electricity that allows the sensor information processing unit 14 to continue the processing of the sensor information at the timing when the processing of the sensor information is interrupted when the interruption condition is satisfied. Is set to In other words, the interruption condition is an amount by which the remaining amount of electricity stored in the electricity storage unit 12 can continue the sensor information processing by the sensor information processing unit 14 at the timing when the interruption information is satisfied and the processing of the sensor information is interrupted. Is set to be.

  Then, when the restart condition is satisfied, the sensor information processing unit 14 acquires the processing information stored in the nonvolatile memory 16 and restarts the processing of the sensor information. The restart condition is a condition determined in consideration of, for example, the remaining amount of electricity stored in the electricity storage unit 12 or the planned consumption amount of energy stored in the electricity storage unit 12.

  That is, in the sensor information transmission apparatus 101, the nonvolatile memory 16 is provided in the processor or as a peripheral circuit of the processor. When the sensor information processing unit 14 satisfies the interruption condition during the processing of the sensor information, the sensor information processing unit 14 saves the processing content of the processor in the nonvolatile memory 16 and stops the processing of the processor.

  In addition, when the resumption condition is satisfied, the sensor information processing unit 14 restarts the processor and restores the processing content saved in the nonvolatile memory 16, and the processor executes sensor information processing from the interrupted location.

  With such a configuration, for example, it is possible to execute a long-time process in which the process is not completed with one power storage amount in the power storage unit 12.

  Here, the processing information saved in the nonvolatile memory 16 includes data stored in a register used by the processor in the sensor information processing unit 14 in processing sensor information.

  Alternatively, the processing information may include an address of an instruction to be executed or executed next by the processor, or may include sensor information itself.

  Further, the processing information may include data stored in the main memory 17 or data stored in the cache memory in the sensor information processing unit 14. Note that at least one of these memories is a non-volatile memory, so that saving of stored data to the non-volatile memory 16 can be eliminated.

  When the sensor information processing unit 14 receives an interruption or notification indicating that the interruption condition is satisfied, or determines that the interruption condition is satisfied, the sensor information processing unit 14 saves the processing information as described above. In addition, when the sensor information processing unit 14 receives an interrupt or notification indicating that the resumption condition is satisfied or determines that the resumption condition is satisfied, the sensor information processing unit 14 restores the processing information as described above.

  Various conditions such as the following are conceivable as conditions for interrupting the processing of sensor information. The sensor information processing unit 14 can also use a combination of the following conditions.

  That is, the sensor information processing unit 14 determines whether or not the interruption condition is satisfied based on the measurement result of the power storage monitoring unit 13. In this case, the interruption condition corresponds to a condition determined in consideration of the remaining amount of electricity stored in the electricity storage unit 12.

  For example, the sensor information processing unit 14 determines that the interruption condition is satisfied when the remaining amount of power stored in the power storage unit 12 is less than a predetermined threshold or the magnitude of the output voltage of the power storage unit 12 is less than a predetermined threshold.

  Specifically, for example, when the power storage unit 12 includes a switch and a plurality of capacitors, and a capacitor that supplies power is sequentially selected, the power storage monitoring unit 13 determines the number of undischarged or discharged capacitors. Based on the above, the remaining amount of electricity stored in the electricity storage unit 12 is determined.

  Alternatively, the sensor information processing unit 14 starts processing the sensor information, specifically, starts processing the sensor information newly received from the sensor 151, or satisfies the restart condition, After resuming processing, the number of processing cycles executed by the processor is counted. Then, the sensor information processing unit 14 counts the number of processing cycles executed by the processor, and determines that the interruption condition is satisfied when the count value reaches a predetermined value. In this case, the interruption condition corresponds to a condition determined in consideration of the consumption amount of energy stored in the power storage unit 12.

  As the threshold value of the number of processing cycles, that is, the predetermined value, for example, a value corresponding to a timing at which a predetermined ratio of power in the power storage unit 12, for example, 50% is consumed, is set.

  Alternatively, the sensor information processing unit 14 determines that the interruption condition is satisfied when a predetermined time has elapsed since the sensor information processing was started. In this case, the interruption condition corresponds to a condition determined in consideration of the consumption amount of energy stored in the power storage unit 12.

  Specifically, the sensor information processing unit 14 sets a value as the interruption condition in the timer 15 and determines that the interruption condition is satisfied when the timer 15 expires.

  In addition, as conditions for restarting the processing of sensor information, the following various conditions can be considered. The sensor information processing unit 14 can also use a combination of the following conditions.

  That is, the sensor information processing unit 14 determines whether or not the restart condition is satisfied based on the measurement result of the power storage monitoring unit 13.

  Specifically, the sensor information processing unit 14 determines that the resumption condition is satisfied when the remaining amount of power stored in the power storage unit 12 is equal to or greater than a predetermined threshold value or the magnitude of the output voltage of the power storage unit 12 is equal to or greater than the predetermined threshold value. . For example, sensor information processing unit 14 determines that the resumption condition is satisfied when charging of power storage unit 12 is completed. In this case, the restart condition corresponds to a condition determined in consideration of the remaining amount of power stored in the power storage unit 12.

  Alternatively, the sensor information processing unit 14 determines that the resumption condition is satisfied when a predetermined time has elapsed after the processing of the sensor information is interrupted. In this case, the restart condition corresponds to a condition determined in consideration of the remaining amount of power stored in the power storage unit 12.

  Specifically, the sensor information processing unit 14 sets a value as a restart condition in the timer 15, and determines that the restart condition is satisfied when the timer 15 expires. However, since the processor is in a dormant state, a hardware timer is used.

  FIG. 6 is a diagram showing a change in the remaining amount of power stored by the interruption process and the restart process in the sensor information transmission apparatus according to the embodiment of the present invention.

  Referring to FIG. 6, first, charging of power storage unit 12 is started (timing t10), and the remaining amount of power stored in power storage unit 12 increases from zero by the power generation operation of power generation unit 11 and reaches P1. And the sensor information processing part 14 starts the calculation process and output process of sensor information (timing t11). And the electrical storage residual amount of the electrical storage part 12 falls with execution of the calculation process and output process of sensor information.

  Next, when the interruption condition is satisfied, the sensor information processing unit 14 writes the processing information being used in the calculation processing and output processing of the sensor information to the nonvolatile memory 16 and saves it, and performs the calculation processing and output processing of the sensor information. The operation is interrupted (timing t12). At this time, the remaining amount of electricity stored in the electricity storage unit 12 decreases and reaches P2. Then, the remaining amount of power stored in the power storage unit 12 rises again from P <b> 1 due to the power generation operation of the power generation unit 11.

  Here, P2 is a value larger than P11, for example, a value larger than the minimum remaining amount of power necessary for saving the processing information as described above.

  Next, when the resumption condition is satisfied, the sensor information processing unit 14 reads out and restores the processing information saved in the nonvolatile memory 16, and resumes the sensor information calculation processing and output processing (timing t13). At this time, the remaining amount of electricity stored in the electricity storage unit 12 has increased to reach P1. And the electrical storage residual amount of the electrical storage part 12 falls again from P1 with execution of the calculation process and output process of sensor information.

  Next, when the interruption condition is satisfied, the sensor information processing unit 14 writes the processing information being used in the calculation processing and output processing of the sensor information to the nonvolatile memory 16 and saves it, and performs the calculation processing and output processing of the sensor information. The operation is interrupted (timing t14). At this time, the remaining amount of electricity stored in the electricity storage unit 12 decreases and reaches P2. Then, the remaining amount of power stored in the power storage unit 12 rises again from P <b> 1 due to the power generation operation of the power generation unit 11.

  Next, when the resumption condition is satisfied, the sensor information processing unit 14 reads out and restores the processing information saved in the nonvolatile memory 16, and resumes the sensor information calculation processing and output processing (timing t15). At this time, the remaining amount of electricity stored in the electricity storage unit 12 has increased to reach P1. And the electrical storage residual amount of the electrical storage part 12 falls again from P1 with execution of the calculation process and output process of sensor information.

  Thereafter, the sensor information processing unit 14 repeats the interruption and resumption of the sensor information processing based on the interruption condition and the resumption condition until the sensor information calculation process and the output process are completed.

  As described above, by setting the interruption condition, the process of the sensor information processing unit 14 is interrupted at the timings t12 and t14 when the interruption condition is satisfied, and thus the remaining amount of electricity stored in the electricity storage unit 12 does not fall below P2. In addition, by setting the resumption condition, the processing of the sensor information processing unit 14 is resumed at timings t13 and t15 when the resumption condition is satisfied, that is, after the remaining power storage amount of the power storage unit 12 reaches P1.

  That is, the sensor information processing unit 14 does not continue to use the energy stored in the power storage unit 12 until the sensor information calculation process and the output process are completed. Instead of using up the energy stored in the power storage unit 12 to complete the output process, the sensor information processing is stopped and the processing information is saved while a predetermined amount of energy stored in the power storage unit 12 remains.

  With such a configuration, the time until the next charging of the power storage unit 12 is completed can be shortened, and the return of the processing information and the restart of the processing of the sensor information can be accelerated, so that the processing of certain sensor information is completed. The waiting time from the start to the processing of new sensor information can be shortened. For example, the overall processing speed of each sensor information acquired sequentially can be improved. Furthermore, it is possible to shorten the sensor information processing time such that the processing is not completed with one power storage amount in the power storage unit 12.

  Here, the sensor information processing unit 14 may be configured to adjust the restart condition according to the remaining amount of processing of the interrupted sensor information.

  Specifically, the sensor information processing unit 14 maintains the current value of P1 when the remaining amount of processing of the suspended sensor information is large, and P1 when the remaining amount of processing of the suspended sensor information is small. Change to a smaller value. The remaining amount of this process is, for example, the remaining time, the number of cycles, or the number of instructions and the number of cycles necessary for executing each instruction until the processing of the interrupted sensor information is completed.

  As a result, in addition to shortening the waiting time until the processing of new sensor information is started after the processing of certain sensor information is completed, the remaining amount of processing of the interrupted sensor information is small. It is possible to accelerate the resumption of processing and shorten the time until the processing of the sensor information is completed.

  As a usage form of the sensor information transmission system 301, it is conceivable that the sensor information transmission system 301 is used as a system in which the interruption of the process and the resumption of the process as shown in FIG.

  Moreover, the use as a system in which the interruption and resumption of the process as shown in FIG. 4 are repeated at relatively long intervals, for example, the process is not interrupted during the daytime when the amount of power generated by the solar cell is large. It is also possible to use the sensor information transmission system 301 in such a form that the interruption occurs.

  FIG. 7 is a flowchart defining an operation procedure when the sensor information transmission apparatus according to the embodiment of the present invention performs sensor information calculation processing and output processing.

  Referring to FIG. 7, first, when sensor information is received from sensor 151 (YES in step S11), sensor information processing unit 14 starts sensor information calculation processing and output processing (step S12).

  Next, the sensor information processing unit 14 determines whether or not the interruption condition is satisfied (step S13). If the interruption condition is not satisfied (NO in step S13), the sensor information processing unit 14 continues the sensor information calculation process and output process (step S14). The sensor information processing unit 14 determines whether or not the interruption condition is satisfied regularly or irregularly until the calculation process and the output process of the sensor information are completed (NO in step S15) (step S15). S13).

  On the other hand, if the interruption condition is satisfied (YES in step S13), the sensor information processing unit 14 writes the processing information in the nonvolatile memory 16 and saves it, and interrupts the sensor information calculation process and output process (step S16). ).

  Next, the sensor information processing unit 14 determines whether or not the restart condition is satisfied in a state where the calculation process and the output process of the sensor information are suspended (step S17). If the restart condition is not satisfied (NO in step S17), the sensor information processing unit 14 continues to interrupt the sensor information calculation process and the output process.

  On the other hand, when the resumption condition is satisfied (YES in step S17), the sensor information processing unit 14 reads out and restores the processing information saved in the nonvolatile memory 16, and resumes the sensor information calculation processing and output processing ( Step S18).

  Here, the processing of sensor information in the sensor information transmission apparatus 101 is often not a complicated processing, and often the same processing is performed each time between sequentially acquired sensor information. In such a case, the processing amount of the processor in the sensor information processing unit 14, the sensor 151, and the like does not vary greatly between the pieces of sensor information, and therefore the consumption schedule of energy stored in the power storage unit 12, for example, the power storage unit 12 It is also possible to suspend and resume the processing of sensor information in consideration of the time until the remaining amount of power storage falls to a predetermined value. In this case, there is a possibility that the amount of power consumption varies between pieces of sensor information.

  Specifically, the sensor information processing unit 14 is not limited to the configuration in which the processing of sensor information based on the remaining amount of power stored in the power storage unit 12 is simply interrupted and restarted. For example, such an operation is performed according to the transmission data length. The structure which determines whether to perform itself may be sufficient.

  FIG. 8 is a flowchart that defines an operation procedure when the sensor information transmission apparatus according to the embodiment of the present invention suspends and resumes the processing of sensor information based on the suspend condition and the resume condition according to the transmission data length. .

  Referring to FIG. 8, first, when sensor information is received from sensor 151 (YES in step S21), sensor information processing unit 14 performs sensor information calculation processing (step S22). In addition, the sensor information processing part 14 does not need to perform the said calculation process, when transmitting the sensor information received from the sensor 151 to the sensor information receiver 201 as it is.

  Next, the sensor information processing unit 14 starts output processing of sensor information received from the sensor 151 or sensor information after processing such as format conversion, and confirms the data length of the sensor information (step) S23).

  If the data length of the sensor information is greater than or equal to the predetermined value (YES in step S23), the sensor information processing unit 14 determines whether the interruption condition is satisfied (step S24). If the interruption condition is not satisfied (NO in step S24), the sensor information processing unit 14 continues the sensor information output process (step S25). The sensor information processing unit 14 determines whether or not the interruption condition is satisfied regularly or irregularly until the sensor information output process is completed (NO in step S26) (step S24).

  On the other hand, if the interruption condition is satisfied (YES in step S24), the sensor information processing unit 14 writes the processing information in the nonvolatile memory 16 and saves it, and interrupts the output process of the sensor information (step S27).

  Next, the sensor information processing unit 14 determines whether or not the restart condition is satisfied in a state where the output process of the sensor information is interrupted (step S28). If the restart condition is not satisfied (NO in step S28), the sensor information processing unit 14 continues to interrupt the sensor information output process.

  On the other hand, when the resumption condition is satisfied (YES in step S28), the sensor information processing unit 14 reads out and restores the processing information saved in the nonvolatile memory 16, and resumes the output process of the sensor information (step S29). .

  In addition, when the data length of the sensor information is less than the predetermined value (NO in step S23), the sensor information processing unit 14 does not interrupt the processing of the sensor information based on the interruption condition, and performs the sensor information output process. The process is executed until completion (step S30).

  As described above, in the sensor information transmission device 101, the sensor information processing unit 14 transmits the sensor information to the wireless transmission unit 18 when the data length of the sensor information to be transmitted to the sensor information reception device 201 is less than the predetermined threshold. Even if the interruption condition is satisfied in the state where the output process to output to is performed, the output process is not interrupted.

  On the other hand, when the data length of the sensor information to be transmitted to the sensor information receiving device 201 is equal to or greater than a predetermined threshold, the sensor information processing unit 14 performs an output process for outputting the sensor information to the wireless transmission unit 18. If the interruption condition is satisfied in the state, the output process is interrupted.

  Specifically, when the transmission data length is short, the sensor information processing unit 14 outputs the sensor information without being aware of the remaining amount of power stored in the power storage unit 12 or the planned amount of energy stored in the power storage unit 12. To complete. On the other hand, when the transmission data length is long, the sensor information processing unit 14 suspends and resumes the processing of the sensor information while paying attention to the remaining amount of power stored in the power storage unit 12 or the planned energy consumption amount stored in the power storage unit 12. Do.

  Further, the sensor information processing unit 14 is not limited to the configuration in which the processing of sensor information based on the remaining amount of power stored in the power storage unit 12 is simply interrupted and restarted, and such an operation is performed depending on the type of sensor information or the type of sensor. The structure which determines whether to perform itself may be sufficient.

  Specifically, for a specific sensor information or a specific sensor, when the number of cycles of the arithmetic processing and the data length of the sensor information are known, it is appropriate to suspend and restart the sensor information processing. It is possible to determine in advance whether it is appropriate to complete the arithmetic processing and output processing without interrupting and resuming the processing of sensor information.

  FIG. 9 defines an operation procedure when the sensor information transmission apparatus according to the embodiment of the present invention suspends and resumes the processing of sensor information based on the suspend condition and the resume condition according to the sensor information or the type of sensor. It is a flowchart.

  Referring to FIG. 9, first, when sensor information is received from sensor 151 (YES in step S41), sensor information processing unit 14 confirms the type of received sensor information or the type of corresponding sensor 151 (step S42). ).

  If the sensor information is not of a specific type and the corresponding sensor 151 is not of a specific type (NO in step S42), the sensor information processing unit 14 starts sensor information calculation processing and output processing (step S42). S43), it is determined whether or not the interruption condition is satisfied (step S44). If the interruption condition is not satisfied (NO in step S44), the sensor information processing unit 14 continues the sensor information calculation process and output process (step S45). Then, the sensor information processing unit 14 determines whether or not the interruption condition is satisfied regularly or irregularly until the calculation process and the output process of the sensor information are completed (NO in Step S46) (Step S46). S44).

  On the other hand, if the interruption condition is satisfied (YES in step S44), the sensor information processing unit 14 writes the processing information in the nonvolatile memory 16 and saves it, and interrupts the sensor information calculation process and output process (step S47). ).

  Next, the sensor information processing unit 14 determines whether or not the restart condition is satisfied in a state where the calculation process and the output process of the sensor information are interrupted (step S48). If the restart condition is not satisfied (NO in step S48), the sensor information processing unit 14 continues to interrupt the sensor information calculation process and the output process.

  On the other hand, when the resumption condition is satisfied (YES in step S48), the sensor information processing unit 14 reads out and restores the processing information saved in the nonvolatile memory 16, and resumes the sensor information calculation processing and output processing ( Step S49).

  In addition, when the sensor information is of a specific type or the corresponding sensor 151 is of a specific type (YES in step S42), the sensor information processing unit 14 interrupts the processing of the sensor information based on the interrupt condition. The sensor information calculation process and output process are executed until completion (step S50).

  As described above, in the sensor information transmission apparatus 101, the sensor information processing unit 14 performs processing of the sensor information based on the interruption condition according to the type of the acquired sensor information or the type of the sensor corresponding to the acquired sensor information. Decide whether to interrupt.

  Specifically, the sensor information processing unit 14 does not recognize the remaining amount of power stored in the power storage unit 12 when the calculation amount of sensor information is small or the transmission data length of the sensor information is short. The calculation processing and output processing are executed until completion. On the other hand, when there is a large amount of calculation processing of sensor information or when the transmission data length of sensor information is long, the sensor information processing unit 14 consumes the remaining amount of power stored in the power storage unit 12 or the energy stored in the power storage unit 12. Suspending and resuming the processing of sensor information in consideration of the planned amount.

  The sensor information processing unit 14 can also use a combination of the transmission data length and the sensor information or the type of sensor in determining whether or not to interrupt the processing of the sensor information based on the interruption condition.

  By the way, in the technique described in Patent Document 1, it is assumed that a series of processes for transmitting a transmission telegram can be completed using energy stored in the energy storage unit. It is desirable to execute appropriate processing considering the stored energy beyond the technique described in Patent Document 1.

  On the other hand, in the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 interrupts the processing of the sensor information when the interruption condition is satisfied in the state of processing the sensor information. To do. The interruption condition is set so that the electricity storage unit 12 has a remaining amount of electricity that allows the sensor information processing unit 14 to continue the processing of the sensor information at the timing when the interruption information is satisfied and the processing of the sensor information is interrupted. Has been.

  In this way, by not using the stored energy of the power storage unit 12 continuously until the processing of the sensor information is completed, but by interrupting the processing of the sensor information while leaving the stored energy of the power storage unit 12 to some extent, The time until the next charging of the power storage unit 12 is completed can be shortened, and the start or restart of the processing of the sensor information can be accelerated. Thereby, it is possible to shorten the waiting time from the completion of processing of certain sensor information to the start of processing of new sensor information. Specifically, for example, the overall processing speed of each piece of sensor information acquired sequentially can be improved, so that the sensor sample interval can be shortened, and the accuracy of measurement using the sensor can be improved. Can do. Furthermore, it is possible to shorten the sensor information processing time such that the processing is not completed with one power storage amount in the power storage unit 12.

  Therefore, in the sensor information transmission device according to the embodiment of the present invention, it is possible to execute appropriate processing in consideration of stored energy in a configuration that operates using power from the power storage unit.

  Further, in the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 detects the sensor information when the data length of the sensor information to be transmitted to the sensor information receiving device 201 is less than a predetermined threshold. Even when the interruption condition is satisfied in the state where the output process for outputting the signal to the wireless transmission unit 18 is performed, the output process is not interrupted.

  As described above, when the transmission data length is short, the transmission of the sensor information is completed without being aware of the remaining amount of power stored in the power storage unit 12 or the planned energy consumption amount stored in the power storage unit 12. Depending on the data length, it is possible to appropriately select whether or not to suspend and resume sensor information processing. Accordingly, it is possible to flexibly optimize the power consumption by the sensor information processing according to the data length of the sensor information, and to shorten the time until the sensor information processing is completed.

  In addition, the possibility that the sensor information receiving apparatus 201 that is the apparatus on the sensor information receiving side can receive the sensor information at a time is increased, and the sensor information receiving apparatus 201 can perform processing using the sensor information better. . Specifically, for example, in the sensor information receiving device 201, when the processing using the sensor information from the sensor information transmission device 101 requires quickness, or the processing using the sensor information from the sensor information transmission device 101 It is more effective when it is not preferable to interrupt the operation.

  Further, in the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 determines that the sensor information when the data length of the sensor information to be transmitted to the sensor information receiving device 201 is equal to or greater than a predetermined threshold. In the state in which the output process for outputting to the wireless transmission unit 18 is being performed, the output process is interrupted if the interrupt condition is satisfied.

  As described above, when the transmission data length is long, the transmission of the sensor information is interrupted and resumed in consideration of the remaining amount of power stored in the power storage unit 12 or the planned consumption amount of stored energy in the power storage unit 12. Depending on the data length, it is possible to appropriately select whether or not to suspend and resume sensor information processing. Thereby, the power consumption by the sensor information processing can be flexibly optimized according to the data length of the sensor information, and the time until the sensor information processing is completed can be shortened.

  Further, in the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 is stored in the remaining amount of power stored in the power storage unit 12 or stored in the power storage unit 12 in a state where processing of sensor information is suspended. When the restart condition determined in consideration of the planned energy consumption amount is satisfied, the processing of the sensor information is restarted.

  In this way, by setting the restart condition, the sensor information processing in the sensor information processing unit 14 can be restarted when sufficient power is prepared.

  Further, in the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 adjusts the restart condition according to the remaining amount of processing of the interrupted sensor information.

  With this configuration, in addition to shortening the waiting time from the completion of processing of certain sensor information to the start of processing of new sensor information, when the remaining amount of processing of interrupted sensor information is small It is possible to accelerate the resumption of the processing of the sensor information and shorten the time until the processing of the sensor information is completed.

  In the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 is configured such that the remaining amount of power stored in the power storage unit 12 is less than a predetermined threshold value or the magnitude of the output voltage of the power storage unit 12 is a predetermined threshold value. If it is less than that, it is determined that the interruption condition is satisfied.

  With such a configuration, the sensor information interruption process can be performed at an appropriate timing according to the state of the power storage unit 12. In other words, the sensor information process can be interrupted at an appropriate timing reflecting the remaining amount of power stored in the power storage unit 12 or the output voltage.

  Further, in the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 determines that the interruption condition is satisfied when a predetermined time has elapsed since the sensor information processing was started.

  Thus, with a simple configuration for measuring the predetermined time, it is possible to set the timing for interrupting the sensor information and to interrupt the processing of the sensor information at a timing desired by the user, for example.

  In the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 includes a processor. The sensor information processing unit 14 counts the number of processing cycles executed by the processor after starting the processing of the sensor information, and determines that the interruption condition is satisfied when the count value reaches a predetermined value.

  With such a configuration, the sensor information processing can be interrupted at an appropriate timing according to the processing time of the processor in the sensor information processing unit 14.

  Further, in the sensor information transmission device according to the embodiment of the present invention, the sensor information processing unit 14 is configured to perform the processing based on the interruption condition according to the type of acquired sensor information or the type of sensor corresponding to the acquired sensor information. It is determined whether or not to interrupt the processing of sensor information.

  With such a configuration, it is possible to appropriately select whether to suspend and resume sensor information processing according to the type of sensor information or the type of sensor. The time until sensor information processing is completed can be shortened.

  Also, in the case of sensor information with a small amount of calculation processing or sensor information with a short transmission data length, sensor information processing and output processing are completed without interrupting and resuming sensor information processing. The sensor information receiving device 201 that is the device on the sensor information receiving side is more likely to receive the sensor information at a time, and the sensor information receiving device 201 executes the process using the sensor information better. can do. Specifically, for example, in the sensor information receiving device 201, when the processing using the sensor information from the sensor information transmission device 101 requires quickness, or the processing using the sensor information from the sensor information transmission device 101 It is more effective when it is not preferable to interrupt the operation.

  Further, in the sensor information transmission device according to the embodiment of the present invention, when the sensor information processing unit 14 satisfies the interruption condition in the state of processing the sensor information, the processing being used in the processing of the sensor information The information is stored in the nonvolatile memory 16 and the processing of the sensor information is interrupted.

  With such a configuration, the processing of the interrupted sensor information can be performed satisfactorily after restarting.

  In the sensor information receiving device according to the embodiment of the present invention, the wireless receiving unit 22 receives sensor information from the sensor information transmitting device 101. Then, the sensor information processing unit 23 processes the sensor information received by the wireless reception unit 22.
