  An object of the present invention is to reduce unnecessary power consumption in a gas meter radio.

  The present inventors have intensively studied to reduce unnecessary power consumption in a gas meter radio. As a result, the following knowledge was obtained.

  The gas meter radio is attached to the gas meter and transmits the amount of gas used by wireless communication. In the gas meter radio, a phenomenon was observed in which the battery was already consumed after it was manufactured at the factory and before it was installed at the final installation site. This was thought to be due to the switch being turned on during transportation and unnecessary power consumption.

  Gas meter radios are often installed outdoors and are generally waterproofed. It is usually difficult to supply power from the outside to a gas meter radio that is in use, for example, because of waterproofing and the absence of an available commercial power source. For this reason, in general, a gas meter radio includes a battery (dry battery or the like) as a power source inside a waterproof and sealed casing. The battery is disposed and sealed inside the housing during manufacture at the factory.

  On the other hand, in a waterproof gas meter radio device, switches are not provided outside the casing in order to ensure the reliability and stability of sealing. A power switch using magnetic force (a switch that turns on or off the power supply from the battery to the main circuit) in order to prevent the battery from being consumed until it is installed and used after it is manufactured at the factory. Is generally provided.

  A specific example of a power switch using magnetic force is a reed switch. When starting to use the gas meter, for example, an installer (engineer) brings magnetic field generation means such as a magnet closer to the vicinity of the reed switch from the outside of the housing. As a result, the reed switch is turned on, energization from the battery to the main circuit is started, and the gas meter radio starts to start.

  Since the power switch is in the OFF state during transportation, in principle, energization from the battery to the main circuit is prohibited until the start of use, and in principle, the battery is prevented from being consumed. However, as a result of investigations by the present inventors, it has been found that the lead inside the reed switch may be brought into contact by vibration during transportation and an ON state may occur. When energization from the battery to the main circuit is started in response to such an ON state and the gas meter radio starts to start up, the battery is consumed until it is shipped from the factory and used. Will occur.

  Based on this knowledge, the present inventors do not start activation only by the occurrence of the ON state of the reed switch, but start the activation only when the temporal pattern of the ON state and OFF state of the reed switch satisfies a predetermined condition. The idea was that if it was started, the occurrence of such problems would be suppressed. In other words, for example, it is unintentionally generated due to vibration during transportation by determining whether to start the operation using not only the change to the ON state but also the change to the OFF state thereafter. It is possible to prevent erroneous start due to the ON state.

  That is, the gas meter radio of the present invention includes a housing, a reed switch disposed inside the housing, and a temporal pattern of ON and OFF states of the reed switch disposed in the housing. An ON-OFF detector that outputs a start signal when a predetermined condition is satisfied, an RF controller that is disposed inside the housing and controls transmission / reception of signals to / from the outside of the housing, In the standby state, the power supply to the RF controller is not performed, and the start operation including the start of power supply to the RF controller is performed based on the start signal output from the ON-OFF detector. A start-up operation controller to be started, and a battery that is disposed inside the casing and supplies power to the reed switch, the ON-OFF detector, the RF controller, and the start-up operation controller.

  With such a configuration, it is possible to reduce unnecessary power consumption during transportation before starting use.

  In the gas meter radio, the predetermined condition may include that the reed switch is continuously on for a predetermined time.

  Further, in the gas meter radio, the predetermined condition is that the time-lapse pattern includes at least two times and one time each of the ON state and OFF state of the reed switch, and the duration of each ON state and OFF state is specified. It may be a predetermined pattern.

  In the gas meter radio, the start-up operation controller supplies power to the RF controller when the start-up operation is started and the RF controller does not receive a signal for instructing the initial setting for a predetermined time. You may be comprised so that it may cut | disconnect and may transfer to a standby state.

  According to the gas meter radio of the present invention, it is possible to reduce unnecessary power consumption during transportation before the start of use.

(First embodiment)
[Device configuration]
FIG. 1 is a block diagram illustrating an example of a schematic configuration of a gas meter radio according to the first embodiment.

  The gas meter radio device 100 according to the present embodiment includes a housing 10, a reed switch 11 disposed in the housing 10, a reed switch 11 disposed in the housing 10, and an ON state of the reed switch 11 in a standby state. And an ON-OFF detector 12 that outputs a start signal when an OFF-state time pattern satisfies a predetermined condition, and control of signal transmission / reception to / from the outside of the housing 10. The RF controller 13 that is disposed inside the housing 10 and does not supply power to the RF controller 13 in the standby state, and is based on the start-up signal output from the ON-OFF detector 12. A start-up operation controller 14 that starts a start-up operation including the start of power supply to the controller 13, a reed switch 11, an ON-OFF detector 12, and an RF controller 13 that are disposed inside the housing 10. The preliminary activation motion controller 14 and a battery 15 for supplying power.

  The housing 10 may be a plastic box, for example. The material of the housing 10 may be any material as long as it can transmit a magnetic field to such an extent that the magnetism generating means can act on the reed switch 11. The housing 10 is preferably sealed after being waterproofed so that rainwater or the like does not enter the interior even when installed outside.

  Specifically, the reed switch 11 has a structure in which, for example, leads made of two ferromagnetic materials face each other with a predetermined contact interval and are enclosed in a glass tube. When a magnetic field is applied from the outside in the axial direction of the lead, the lead is magnetized, and an attractive force is generated between the opposing free ends. Further, if the magnetic field is erased, it is turned off by the elasticity of the lead. That is, in a normal state where the magnetic field is weak, at least one of the leads is biased in a direction away from the other lead, and the contact is brought into contact by the action of a magnetic force opposite to the biasing force when the lead is magnetized by the magnetic field. .

  Specifically, the ON-OFF detector 12 includes, for example, a microcontroller, an MPU, a PLC (Programmable Logic Computer), a logic circuit, and storage means such as a memory in which a program, determination conditions, and the like are stored. And a timer (such as a timer circuit). The ON-OFF detector 12 is preferably electrically connected to the reed switch 11 so that the ON state and the OFF state of the reed switch 11 can be detected.

  Specifically, the RF controller 13 can include, for example, an antenna, an amplifier, an oscillator, and the like.

  Specifically, the activation operation controller 14 can be configured by, for example, a microcontroller, an MPU, a PLC (Programmable Logic Computer), a logic circuit, and the like, and a storage unit such as a memory in which a program is stored. The activation operation controller 14 may be configured by a single controller that performs centralized control, or may be configured by a plurality of controllers that perform distributed control in cooperation with each other. The activation operation controller 14 is preferably connected to the ON-OFF detector 12 so as to be able to receive an activation start signal from the ON-OFF detector 12. The activation operation controller 14 is preferably connected to the RF controller 13 so as to be able to control the RF controller 13. The start-up operation controller 14 may have a function of a controller that controls the operation of the gas meter radio 100 during normal operation. Or the controller which controls operation | movement of the radio | wireless machine 100 for gas meters at the normal time may be provided separately from the starting operation controller 14.

  Specifically, the battery 15 can be constituted by, for example, a dry battery, a storage battery, or the like. The connection relationship between the battery 15 and other components is arbitrary. For example, it can be configured to be connected to the ON-OFF detector 12 and the activation operation controller 14, and to supply power from the battery 15 to the RF controller 13 via the activation operation controller 14. Alternatively, the battery 15 may be connected only to the ON-OFF detector 12, and power may be supplied from the battery 15 to the activation operation controller 14 and the RF controller 13 via the ON-OFF detector 12.

  As the battery 15, a common battery that supplies power to each component including the reed switch 11, the ON-OFF detector 12, the RF controller 13, and the activation operation controller 14 may be provided. A plurality of batteries may be separately provided to supply power to each of the components. Alternatively, a single battery or a plurality of batteries may be provided separately for each arbitrary combination of components.

  The ON-OFF detector 12, the RF controller 13, and the start-up operation controller 14 may each be configured with a single component (chip or the like), or may be configured with a plurality of components. . Alternatively, the ON-OFF detector 12, the RF controller 13, and the activation operation controller 14 may be configured as an integral part in any combination.

  The “ON-time and OFF-state temporal pattern” is a pattern defined by how the reed switch ON state and OFF state appear along the time axis. The temporal pattern may include at least one change from the OFF state to the ON state (hereinafter referred to as ON change) and the subsequent change from the ON state to the OFF state (hereinafter referred to as OFF change). In the case where the temporal pattern includes one ON change and one OFF change thereafter, for example, it can be specified by the duration of one ON state (hereinafter, ON state duration). In the case of an ON change, a subsequent OFF change, and a subsequent ON change, for example, it can be specified by one ON state duration and one OFF state duration (hereinafter referred to as OFF state duration). .

  “When a predetermined condition is satisfied” refers to a case where the temporal pattern satisfies a certain condition. For example, when the duration from a certain ON change to the next OFF change exceeds a predetermined time, or when the duration exceeds a predetermined time, a plurality of ON changes and a plurality of OFFs are determined for a predetermined time. This includes cases that occur at intervals.

  “Based on the activation start signal” means that the activation start signal is directly input from the ON-OFF detector 12 to the normal operation controller 14 and the normal operation controller 14 starts activation, and the activation start signal is ON. -It includes both of cases where the normal operation controller 14 starts to be activated when a predetermined signal or the like is inputted from the component to the other operation elements to the normal operation controller 14.

[Operation]
FIG. 2 is a flowchart illustrating an example of a schematic operation of the gas meter radio according to the first embodiment. When the manufacture of the gas meter radio device 100 is completed in a factory or the like, the gas meter radio device 100 is set in a standby state (start). The standby state is a so-called sleep mode for minimizing the power consumption after the manufacture until the start of use. In the standby state, power supply from the battery 15 to the RF controller 13 is cut off. In the standby state, the power supply to not only the RF controller 13 but also the normal operation controller 14 may be cut off. In the standby state, power supply to all components other than the reed switch 11 and the ON-OFF detector 12 may be cut off.

  The ON-OFF detector 12 acquires the temporal pattern of the ON state and OFF state of the reed switch 11 (step S101). The acquisition may be performed by any method, for example, may be acquired at any time so as to be updated every 10 seconds, and the ON state duration is specified for the ON state every time the ON state occurs. It is good to do.

  Thereafter, the ON-OFF detector 12 determines whether or not the temporal pattern satisfies a predetermined condition (step S102). If the determination result is NO, the process returns to step S101 again.

  If the determination result in step S <b> 102 is YES, the ON-OFF detector 12 outputs a start signal to the start operation controller 14. Upon receiving the activation start signal from the ON-OFF detector 12, the activation operation controller 14 starts an activation operation including the start of power supply to the RF controller 13 (step S103), and the standby state ends (end). ). With this operation, use of the gas meter radio 100 is started.

  After the start of use, the gas meter radio 100 uses a reading unit (not shown) (for example, a reading reed switch for reading out a measurement result from the gas meter, which is the same component as the reed switch 11 or a separate component). Read the measurement result. The gas meter radio 100 transmits the measurement result via the RF controller 13 after accumulating in a storage unit or the like as necessary. Since means and method for reading out the measurement result from the gas meter and means and method for accumulating or transmitting the measurement result can be used, a description thereof is omitted.

  There are various methods for generating a desired magnetic field around the reed switch 11 in a desired pattern so that the time-lapse pattern of the ON state and the OFF state of the reed switch 11 satisfies a predetermined condition.

  For example, the installer may bring magnetism generating means such as a bar magnet close to the reed switch 11 from the outside of the housing, and generate the ON state and OFF state of the reed switch 11 so as to satisfy the “predetermined condition”.

  The magnetism generating means does not necessarily have to be a bar magnet, and any configuration can be used as long as it can generate the ON state and the OFF state of the reed switch 11 so as to satisfy the “predetermined condition”. Also good. A magnetic field having a predetermined pattern may be automatically generated by a computer-controlled electromagnet or the like. When a human generates a magnetic field with a bar magnet, it is difficult to perform strict control. Therefore, it is preferable to make a determination with an allowable range (margin) as appropriate.

  According to the configuration of the present embodiment, it is possible to reduce unnecessary power consumption during transportation before starting use.

[Example 1]
FIG. 3 is a diagram illustrating an example of a temporal pattern of an ON state and an OFF state of a reed switch in the gas meter radio according to the first embodiment. FIG. 3A illustrates an example of a temporal pattern generated by vibration during transportation. FIG. 3B is a diagram showing an example of a temporal pattern when the installer starts the gas meter.

In this embodiment, the predetermined condition includes that the ON state of the reed switch continues for a predetermined time. That is, in the example of FIG. 3, the temporal pattern is specified by one ON state duration (t _ON ). The “predetermined condition” is that the ON state duration time is equal to or greater than T, which is a predetermined time.

  The ON-state duration is measured, for example, when the ON-OFF detector 12 starts counting the timer circuit when changing from the OFF state to the ON state, and finishes counting the timer circuit when changing from the ON state to the OFF state. Can be done.

  As illustrated in FIG. 3A, in the vibration during transportation, the time for which the reed switch 11 is in the ON state is almost short (for example, less than 0.5 seconds). Therefore, for example, T = 1 second, and the ON-OFF detector 12 determines whether the ON state duration is 1 second or longer. In the example of FIG. 3A, the ON state is generated three times by vibration during transportation, but the ON state duration is shorter than 1 second in any case. Therefore, the ON-OFF detector 12 does not transmit an activation start signal to the activation operation controller 14 and can prevent unintended activation.

As illustrated in FIG. 3B, when the installer keeps the bar magnet close to the reed switch 11, t _ON ≧ T. The ON-OFF detector 12 determines that the time-lapse pattern specified by one ON state duration (t _ON ) satisfies a predetermined condition, and transmits an activation start signal to the activation operation controller 14. With this operation, activation can be started according to the intention of the installer.

[Example 2]
FIG. 4 is a diagram illustrating an example of a temporal pattern of an ON state and an OFF state of a reed switch in the gas meter radio according to the second embodiment. FIG. 4A illustrates an example of a temporal pattern generated by vibration during transportation. FIG. 4B is a diagram illustrating an example of a temporal pattern when the installer starts activation of the gas meter.

In the present embodiment, the predetermined condition is that the temporal pattern includes at least two times and one or more times each of the ON state and OFF state of the reed switch, and the duration of each ON state and OFF state is specified. It is to be a predetermined pattern. In the example of FIG. 4, the time-lapse pattern is specified by the durations (t _ON and t _OFF ) of the ON state and the OFF state that occur during TR, which is a predetermined time. More specifically, the duration of the first ON state (t _ON1 ) and the duration of the first OFF state that occurs next (t _OFF1 ) in 10 seconds (TR) after the occurrence of the ON state. and, the duration of the second time of the oN state occurring in the next and _{(t ON2),} the duration of the second time of the OFF state occurring in the next and _{(t OFF2),} the duration of the third oN state that occurs in the next (T _ON3 ). "Predetermined condition" is, for _{example, t ON1} and _{t ON3} and _{t OFF1} and _{t OFF2} and is by 1 _{second, t ON2} can be two seconds. When the installer operates with a magnet, a predetermined margin is taken, for example, 0.7 seconds ≦ t _ON1 ≦ 1.3 seconds, 0.7 seconds ≦ t _OFF1 ≦ 1.3 seconds, 1.5 seconds ≦ t _ON2 ≦ 2.5 seconds, 0.7 seconds ≦ _{t OFF2} ≦ 1.3 seconds, may be the fact that none of the 0.7 seconds ≦ _{t ON3} ≦ 1.3 seconds is satisfied.

  The OFF-state duration is measured, for example, when the ON-OFF detector 12 starts counting the timer circuit when the ON state changes to the OFF state, and when the ON-OFF detector 12 changes from the OFF state to the ON state. 12 can be performed by finishing the count of the timer circuit.

In this embodiment, after the first ON state occurs, the timer circuit starts counting, and then the first OFF change, the second ON change, the second OFF change, the third ON change, the third time The time when each of the OFF changes occurs is acquired as the count value of the timer circuit. When the count value of the timer circuit reaches 10 seconds, the timer circuit stops counting. Therefore, there is a case where the third OFF change does not necessarily occur in 10 seconds. In this case, the corresponding t _ON and t _OFF are zero.

In the example of FIG. 4 (a), the vibration during _{transportation,} t ON1 = 0.4 _{sec, t OFF1} = 2 _seconds, t ON2 = 0.7 _{sec, t} OFF2 = 1.8 _{sec, t} ON3 = 0. It is 4 seconds. _the above condition is satisfied for t _ON2, does not satisfy the above conditions for _{t ON1, t OFF1, t OFF2} , t ON3. Therefore, the ON-OFF detector 12 does not transmit an activation start signal to the activation operation controller 14 and can prevent unintended activation. In particular, in this embodiment, the second ON state continues for a long time of 0.7 seconds, but appropriate control is possible even when such an abnormality occurs.

At the beginning of use, the installer brings the bar magnet close to the reed switch 11 for about 1 second, then releases it for about 1 second, then closes for about 2 seconds, then releases it for about 1 second, and then only for about 1 second. Move closer and away. In _the example of FIG. _{4 (b), t ON1 =} 0.8 _seconds, and _{t OFF1} = 1 _second, t ON2 = 2.4 _{sec, t OFF2} = 1 _second, t ON2 = 0.8 seconds and the like. _{t ON1, t OFF1, t ON2} , t OFF2, the above conditions are satisfied for _{t ON3.} ON-OFF detector 12 has three ON state duration _{(t ON1, t ON2, t} ON3) and two OFF state duration _{(t OFF1,} t _OFF2) aging pattern is predetermined specified by condition Is satisfied, and a start signal is transmitted to the start operation controller 14. With this operation, activation can be started according to the intention of the installer.

[Modification]
FIG. 5 is a flowchart illustrating an example of an outline of the operation of the gas meter radio according to the modification of the first embodiment. The apparatus configuration of the gas meter radio of this modification can be the same as that of the gas meter radio 100 of FIG.

  When the manufacture of the gas meter radio is completed in a factory or the like, the gas meter radio is set to a standby state (start). The standby state is a so-called sleep mode for minimizing the power consumption after the manufacture until the start of use. In the standby state, power supply from the battery to the RF controller is cut off.

  The ON-OFF detector determines whether an ON state is detected (step S201), and repeatedly executes step S201 while the determination result is NO. When the determination result is YES, a temporal pattern of the ON state and OFF state of the reed switch is acquired (step S202).

  Thereafter, the ON-OFF detector determines whether or not the temporal pattern satisfies a predetermined condition (step S203). If the determination result is NO, the process returns to step S201 again.

  When the determination result of step S203 is YES, the ON-OFF detector outputs a start start signal to the start operation controller. When receiving the activation start signal from the ON-OFF detector, the activation operation controller starts the activation operation including the start of power supply to the RF controller (step S204) and ends the standby state (end). With this operation, use of the gas meter radio is started.

  Since operations other than those described above can be the same as those described above in the first embodiment, description thereof will be omitted.

  Even in this modification, it is possible to reduce unnecessary power consumption during transportation before starting use. Moreover, since the acquisition of the time-lapse pattern is also waited until the ON state is detected, the power consumption can be further reduced.

(Second Embodiment)
Since the apparatus configuration of the gas meter radio device of the second embodiment can be the same as that of the gas meter radio device 100 of the first embodiment, the description thereof will be omitted.

  In the second embodiment, the activation operation controller cuts off the power supply to the RF controller when the activation signal is not received for a predetermined time after the activation operation is started. To enter the standby state.

  FIG. 6 is a flowchart illustrating an example of an outline of the operation of the gas meter radio according to the second embodiment.

  When the manufacture of the gas meter radio is completed in a factory or the like, the gas meter radio is set to a standby state (start). The standby state is a so-called sleep mode for minimizing the power consumption after the manufacture until the start of use. In the standby state, power supply from the battery to the RF controller is cut off.

  The ON-OFF detector determines whether or not an ON state is detected (step S301), and repeatedly executes step S301 while the determination result is NO. If the determination result is YES, a temporal pattern of the ON state and OFF state of the reed switch is acquired (step S302).

  Thereafter, the ON-OFF detector determines whether or not the temporal pattern satisfies a predetermined condition (step S303). If the determination result is NO, the process returns to step S301 again.

  When the determination result of step S203 is YES, the ON-OFF detector outputs a start start signal to the start operation controller. When receiving the activation start signal from the ON-OFF detector, the activation operation controller starts the activation operation including the start of power supply to the RF controller (step S304).

  Thereafter, the activation operation controller determines whether or not the RF controller receives a signal for instructing the initial setting within a predetermined time after the activation operation is started (step S305). If the determination result is NO, the power supply to the RF controller is stopped and the process again enters a standby state (step S306), and the process returns to step S301. The signal for instructing the initial setting may be transmitted by the installer through a handy terminal (not shown).

  If the decision result in the step S305 is YES, the activation operation controller maintains the power supply to the RF controller and ends the standby state (end). With this operation, use of the gas meter radio is started.

  Since operations other than those described above can be the same as those described above in the first embodiment, description thereof will be omitted.

  Also in this embodiment, it is possible to reduce unnecessary power consumption during transportation before starting use. Moreover, since the acquisition of the time-lapse pattern is also waited until the ON state is detected, the power consumption can be further reduced. In addition, even after the start-up operation starts, if the initial setting is not performed, it is possible to shift to the standby state again, so even if a correct time-lapse pattern occurs accidentally at an unintended timing, the transition to the standby state occurs again. By minimizing the power supply to the RF controller, power consumption can be further reduced.

  In the present embodiment, step S301 may be omitted. In this case, step S302 can be the same operation as step S101. In other words, the temporal pattern may be acquired by any method, for example, may be acquired at any time so as to be updated every 10 seconds, or the ON state is continued for the ON state every time the ON state occurs. It is good also as specifying time.

  From the foregoing description, many modifications and other embodiments of the present invention are obvious to one skilled in the art. Accordingly, the foregoing description should be construed as illustrative only and is provided for the purpose of teaching those skilled in the art the best mode of carrying out the invention. The details of the structure and / or function may be substantially changed without departing from the spirit of the invention.

  The gas meter radio of the present invention is useful as a gas meter radio capable of reducing unnecessary power consumption during transportation before the start of use.
