[0055] next, be incorporated in being used among the control circuit 10a and measure gas flow, carry out the predetermined processing and the flow measurement processing unit of delivery rate information briefly discussing.As shown in Figure 5 and Figure 6, gas meter, flow meter 2 has fuel gas inlet 2a and gas outlet 2b, and be provided with the gas cutting-off valve 2c that is used for cutting off combustion gas at abnormal time, and a pair of ultrasonic sensor 17 that is used for measuring the gas flow in the fuel gas flow path between entrance and exit, and have pressure transducer 2d, be used to detect the gaseous-pressure that places from the downstream of ultrasonic sensor.Be used for based on the signal from ultrasonic sensor 17 calculate gas flow installation the control circuit board 10 of control circuit 10a be placed as and make LCD 10e towards the display part 2e of gas meter, flow meter 2, recover button 2g and be changed to the device that is used for artificial execution recovery operation after gas cutting-off valve 2c operation.
[0056] is used to measure that the control circuit 10a of gas flow and flow measurement portion 17 can measure that response flow is crossed the flow in fuel gas flow path and travel-time of changing, in the fuel gas flow path, arrange a pair of ultrasonic sensor, measure flow thus, for example, as shown in figure 10.Structure will be discussed hereinafter: be used for transmitting or receive hyperacoustic first transceiver 17A and be used to receive or the second transceiver 17B that transmits is disposed in flow direction, and between can and receiving in transmission, the measurement control part 18 with switch unit switches, described switch unit forms the part of control circuit 10a, and the flow state of the fluid of combustion gas etc. is detected.The signal of the first transceiver 17A and the second transceiver 17B is processed, and flow is measured.Particularly, at first, drive the first transceiver 17A by measuring control part 18, and ultrasound wave is transmitted towards the second transceiver 17B, that is, transmit downstream from the upstream.The signal that receives by the second transceiver 17B is amplified by the amplifying unit that is provided with in measuring control part 18, and compare with reference signal, and after the signal that detects greater than reference signal, by being arranged on the repetitive of measuring in the control part 18, repeat above-mentioned transmission and receive predetermined times, and come the Measuring Time value such as the such timing unit of timer in the control part 18 by being arranged on to measure.
[0057] next, the transmission of the first transceiver 17A and the second transceiver 17B and reception are switched by the measurement control part 18 with switch unit, ultrasonic signal is transferred to the first transceiver 17A from the second transceiver 17B, promptly upstream transmit from the downstream, repeat this transmission as mentioned above, and measure described time value.Poor from the ultrasonic propagation time between the first transceiver 17A and the second transceiver 17B, consider the size of flow path 16 and the flow state of fluid, signal processing unit 19 obtains flow value.Resulting flow value data are accumulated among the information memory cell 10b, and at each predetermined amount of time it are stored as the data of accumulation.
[0058] is used for being set at the flow path 16 that is placed with flow measurement portion 17 at the cutting-off valve 2c that flows of abnormal time cut-out combustion gas, if and the flow value that obtains by signal processing unit 19 is a lot of unusually, perhaps be detected as and surpass the service time of considering usually, then determine unusual the generation, and operation cutting-off valve 2c is used to cut off fuel gas flow path 16.
[0059] if, perhaps import the signal of unusual gaseous-pressure, then, be used to cut off fuel gas flow path 16 by control circuit 10a operation cutting-off valve 2c from pressure transducer 2d from testing shake instrument input shake ground or impact signal, and the notice center.
[0060] next, will example that use the information transmission that is incorporated in the wireless module 11 in the gas meter, flow meter 2 be discussed.At first, if by base station 14, from gas company 15 transmission instrument reading orders, the wide-area communication wireless module 11a that then is incorporated in the gas meter, flow meter receives order, and instrument reading order information is sent to the control circuit 10a that is installed on the same plate in wide-area communication frequency band (200MHz).In each preset time section, the data on flows of measuring in the flow measurement unit is accumulated in control circuit 10a, and the cost data that cumulative data or cumulative data were converted to is stored among the information memory cell 10b.When the instrument reading order information from gas company 15 is transfused to, by communication switch unit 10c, control circuit 10a is sent in the cost data information that flow accumulation data or cumulative data among the information memory cell 10b are converted to area communication wireless module 11b and wide-area communication wireless module 11a, and wide-area communication wireless module 11a transmits to base station 14 with wide-area communication frequency band (200MHz), and uses from the base station 14 dedicated lines to gas company 15 that instrument is read information to transmit.Area communication wireless module 11b transmits to the wireless module 11c that integrally is attached to such as on the particular terminal 12 of TV 12a with specific low power wireless communication frequency band (429MHz), and on screen, show cost information and use amount, for example, shown in Fig. 9 (a).Finish after the transmission of particular terminal 12, notice is finished signal and is transferred to gas company 15, is used to notify gas company, finishes to consumer's information transmission, as mentioned above.
[0061] if in the situation that causes cutting-off valve 2c operation owing to earthquake, impact etc., diagnoses out reason, and the recovery order from gas company 15 is transmitted with wide-area communication frequency band (200MHz) by base station 14, the wide-area communication wireless module 11a that then is incorporated in the gas meter, flow meter 2 receives order, and sends the recovery command information to the control circuit 10a that is installed on the same plate.When input recovers command information, control circuit 10a by communication switch unit 10c to area communication wireless module 11b send be stored among the information memory cell 10b with the relevant information of resuming work, area communication wireless module 11b transmits information with specific low power wireless communication frequency band (429MHz) to the wireless module 11c that integrally is attached on the display terminal 12 such such as TV 12a then, and for example showing the program of resuming work on the screen, shown in Fig. 9 (b).Finish after display terminal 12 transmission, notice is finished signal and is transferred to gas company 15, is used to notify gas company to finish to consumer's information transmission, as mentioned above.
[0062] as mentioned above, control circuit 10a has communication switch unit 10c, is used in response to information waiting for transmission, is chosen in and the different wireless module in the corresponding communication band of communication party aspect; For example, for instrument reading order from gas company 15, according to the information that in wide-area communication wireless module 11a, receives, the informational needs that is stored among the information memory cell 10b is transferred to gas company 15 and particular terminal 12, in this case, for example, has the wide-area communication wireless module 11a of 200MHz communication band, for example, it is selected to have an area communication wireless module 11b of the specific low power wireless communication frequency band of 429MHz; And for recovery order from gas company 15, the information that is stored among the information memory cell 11b only needs to be transferred to particular terminal 12, under this kind situation, for example, the area communication wireless module 11b with the specific low power wireless communication frequency band of 429MHz can be selected.
[0063] wide-area communication wireless module 11a and area communication wireless module 11b can be provided with separatedly, perhaps can be made as general wireless module, and communication band can be switched between wide-area communication frequency band and specific low power wireless communication frequency band.In the former, communication switch unit 10c need select wide-area communication wireless module 11a and area communication wireless module 11b; Though Tong Xin advantage exists simultaneously, the shortcoming that it exists this big installing space and cost to increase.In the latter, communication switch unit 10c need switch communication band accordingly with the communication party; Though the advantage that exists little installing space and cost to reduce, the shortcoming that exists are can not communicate by letter simultaneously, but use over-over communication.
[0064] next, the security monitoring of the Gas appliance in the gas meter, flow meter with communication function as mentioned above will be talked about.Usually, be used for the device that is set continuous service time and when continuous service time is over and done with, cuts off combustion gas in response to flow as being used to limit the device of continuous service time, being known that to prevent to close the accident that Gas appliance etc. causes owing to forgetting.
[0065] yet, in aforesaid general utensil security monitoring, in response to gas flow is set continuous service time equably, and do not consider the type of Gas appliance, and corresponding service time of unique use with each Gas appliance is not set; For example, for the up-to-date Gas appliance with overall safety function and have relatively poor security function experience the Gas appliance in 20 years, though they all are Gas appliances, it is restricted to identical service time if flow range is identical.Limit service time if utilize up-to-date Gas appliance to be used as benchmark, forget that then the time that prevents of closing the Gas appliance that has experienced 20 years is elongated, and risk increases.On the contrary, limit service time if utilize the Gas appliance that has experienced 20 years to be used as benchmark, then take place closing phenomenon the morning of up-to-date combustion gas device, this is a problem.
[0066] the present invention is intended to address the above problem, and provide the monitor units that use difference to settle the standard by as described below, promptly, except monitoring by flow range the method for continuous service time, by obtain individually with have insufficient security function and because they are different with up-to-date Gas appliance the relevant device information of old-fashioned Gas appliance that need be monitored, change continuous service time as required based on instrument information, and monitor Gas appliance.
[0067] then, at first, will be discussed below the acquiring unit of the instrument information of described Gas appliance, that is, because described Gas appliance is distinguished especially with other Gas appliances of installing in the family, so need be monitored.
[0068] as disclosed in patent documentation 1 or 2, utensil is determined the traditional acquiring unit use traffic information or the acoustic information of information, and its determinacy is lower, and needs complex devices.In the present embodiment, solved traditional problem, and provide and have simple structure and high deterministic instrument information acquiring unit.
[0069] particularly, as shown in Figure 3, instrument information transmitter 26 comprises: utensil wireless module 11d, its have be incorporated in gas meter, flow meter 2 in the identical communication band of area communication wireless module 11b; Utensil detecting unit 22, be used for detecting generation with the discharge noise that accompanies at the high-voltage discharge of ignition operation lighter, the discharge noise is converted to the operation commencing signal of utensil, and be used for exporting this signal to utensil wireless module 11d, wherein, described ignition operation is always carried out in the operation start time of Gas appliance; And drive battery supply 23, wherein, described utensil wireless module 11d and utensil detecting unit 22 are placed among on the utensil wireless module plate 24 one, and are installed in the shell 25, to form instrument information transmitter 26.
[0070] instrument information transmitter 26 is installed in the Gas appliance, perhaps is attached to the correct position of outer cover.At this moment, become and the instrument information transmitter to be set detected position at the discharge noise of lighter.For example, as shown in Figure 2, for gas warm-air machine 9, simply by instrument information transmitter 26 being attached to the inside of utensil or the appropriate location on outer cover surface, discharge noise that can check point firearm 4a, and the operation that can detect gas warm-air machine 9 under the situation of the controller that is free of attachment to the gas warm-air machine 9 that is used for received signal begins.Only this means that by instrument information transmitter 26 being placed on the position of the discharge The noise that is subjected to lighter 4a operation that just can appliance begins.Therefore, the instrument information transmitter can be set at the position of any needs, and can install discretely, and can never need the Gas appliance of the transmission of instrument information to separate thus, and can easily replace and be provided with etc.
[0071] no matter because the utensil type, the firing system of Gas appliance nearly all is the high-voltage discharge type, begins so be used to detect the operation such as the so old-fashioned Gas appliance of fast water heater or gas cooking appliance that the utensil detecting unit 22 of discharge noise can detect except gas warm-air machine 9.
[0072] method that begins as a kind of operation of appliance, except detecting above-mentioned discharge noise, also detect the temperature variation that the burn operation with utensil takes place, for example, delivery temperature, warm braw temperature or warm water temperature degree, not under the situation of utensil controller received signal, the operation that can detect Gas appliance begins thus.In order to form the instrument information transmitter in the temperature variation detection method, temperature sensor need be attached to the detection position, and is connected with transmission unit.
[0073] in this embodiment, the control block diagram that utilizes Fig. 4 is gone through the method that detects the discharge noise.
[0074] when gas warm-air machine 9 beginning ignition operations, the lighter operation begins discharge between the electrode that is connected to the high voltage outgoing side, and the combustion gas that provides is lighted, and takes fire.At this moment, and between the electrode electric discharge phenomena together, the discharge noise radiation to around locate.22a detects the discharge noise by the discharge noise detection unit, if and detect the discharge noise, then operate commencing signal converting unit 22b and be converted into predetermined operation commencing signal, and this signal is input to the operation commencing signal determining unit 11e of utensil wireless module 11d, is used for determining whether signal is to operate commencing signal normally.If determine that the result is normal, then this signal is sent to instrument information transmission unit 11f, and unique recognition coding of the gas warm-air machine 9 that is provided with in recognition coding change unit 27 is given, and be transferred to the area communication wireless module 11b of gas meter, flow meter 2, be used as instrument information.According to sequence of operation, under the situation that does not have to receive from the signal of the controller of utensil, operation that can appliance begins, and this signal can be transferred to gas meter, flow meter 2.If discharge noise detection unit 22a detects the discharge noise more than once at short notice, determine then that because the igniting error ignition operation is performed more than once, and the data on flows of this moment also is considered for suppressing to operate the output of commencing signal.
[0075] though by describing present embodiment as an example with gas warm-air machine 9, self-evident is also can carry out similar detection in any other Gas appliance.
[0076] uses the instrument information that so obtains and the instant flow measurement function by the ultrasonic sensing device, for specific Gas appliance provides that difference settles the standard and the security monitoring that specific Gas appliance and other Gas appliances make a distinction can be implemented.
[0077] next, will utilize Figure 11 that whole security monitoring is discussed.
[0078] at first, in common utensil security monitoring, when using Gas appliance, the instant flow that is obtained by flow measurement unit 17 is sent to flow range detecting unit 40, and it detects flow range any that instant flow falls into prior classification then.Measured by running time measuring unit 41 the continuous service time of the Gas appliance in the flow range that detects, and be stored in the running time storage unit 42 according to flow range.Next, when detecting corresponding Gas appliance, uses when stopping flow range detecting unit 40, the running time of storage is confirmed as continuous service time in according to the running time storage unit 42 of flow range, and is stored in the running time determining unit 43 according to flow range.Be formed for monitoring continuous service time of the monitor unit 44 of continuous service time thus according to the flow range that changes according to the Gas appliance type.
[0079] storage list service time according to flow range of in advance storing continuous pot life according to flow range 45 is provided, and comparing unit 46 relatively is stored in according to the value that whether has surpassed storage list continuous service time in the running time determining unit 43 of flow range, and carries out predetermined processing in response to comparative result.Therefore, be scheduled to continuous pot life, and the storage unit 47 service time according to flow range of this time of storage is set by the flow range that the type according to Gas appliance changes.
[0080] in comparing unit 46, if surpass predetermined the allowed time continuously service time, then determine such as forgetting that closing the so unusual use of Gas appliance takes place, and shutoff signal is sent to cutting-off valve driving circuit 48, is used to carry out the rupturing operation of cutting-off valve 2c.Also signal is sent to wide-area communication wireless module 11a and area communication wireless module 11b, and be transferred to base station 14 and particular terminal 12 through information continuous service time.
[0081] therefore, under situation about will use for a long time as benchmark, by continuous service time of function for monitoring, can be implemented in to use easily and between the safety and have well balanced security monitoring, for example forget and close nearest Gas appliance with security function completely etc.
[0082] yet, if having used the security monitoring of long old-fashioned Gas appliance carries out based on described benchmark, then in the allowed time of continuous pot life, the possibility height that unusual superheated or unusual burning occur, and security function is incomplete in some cases, in this case, abnormal occurrence continues.
[0083] then, in the present embodiment, instrument information transmitter 26 is attached in the old-fashioned Gas appliance to be needed on the monitored utensil especially, the instrument information that use sends from instrument information transmitter 26, monitor the power lifetime to specific Gas appliance, based on at the different determined value of value according to the service time of storage in the storage unit 47 of flow range, determine, for example, according to definite allowed time such as the usage time interval of particular appliance and type or user's family structure, and the supervision level can strictly be formulated.
[0084] particularly, when area communication wireless module 11b receives instrument information from the instrument information transmission unit 11f transmission of instrument information transmitter 26, the particular appliance monitor unit 10f of control circuit 10a determines which Gas appliance to have transmitted the operation commencing signal from by particular appliance determining unit 33, is the time point that reduces side from fluctuations in discharge to fluctuations in discharge for the time point that increases side, by fluctuations in discharge detecting unit 34, detect from the instant flow value of measuring by flow measurement unit 17 at that time; By running time measuring unit 35 Measuring Time; And send the result to particular appliance running time storage unit 36.For example, from the flow value of being measured by flow measurement unit 17, particular appliance running time storage unit 36 obtains the average flow value, determines that it is the running time of particular appliance, and sends it to particular appliance running time determining unit 37.
[0085] comparing unit 39 relatively should the time and by the continuous service time of particular appliance in particular appliance continuous service time of the storage list 38 that is stored in particular appliance storage unit service time 10g in advance, and surpass continuous service time during storing value when particular appliance power lifetime, send shutoff signal to cutting-off valve driving circuit 48, be used to carry out the rupturing operation of cutting-off valve 2c, and signal sent to wide-area communication wireless module 11a and area communication wireless module 11b, and be transferred to base station 14 and particular terminal 12 through information service time continuously.
[0086] therefore, based on the specific Gas appliance information of obtaining, follow to be monitored the power lifetime of Actual combustion, and should compare the time with the determined value that is higher than default supervision level, thus, need to be determined the suitable continuous service time of the careful old-fashioned Gas appliance that uses, and definite result can report to necessity side such as the base station, make with by forgetting that the precarious position that the long-time unusual operating position of closing Gas appliance etc. and causing accompanies can be stoped reliably.
[0087] Figure 12 and Figure 13 show the different embodiment of security monitoring.Parts identical in the embodiment of Figure 10 and Figure 11 will no longer be discussed.
[0088] in the present embodiment, similar to the embodiment of Figure 10 and Figure 11, instrument information transmitter 26 is attached on the utensil that needs special surveillance in old-fashioned Gas appliance, the instrument information that use sends from instrument information transmitter 26, to according to flow range service time storage unit 47 storage list service time according to flow range 45 change, after changing storage list, monitor the power lifetime to all Gas appliances of comprising specific Gas appliance, determine based on the different determined value of storing value of service time in the storage unit 47 when common according to flow range, for example, according to definite allowed time such as the usage time interval of particular appliance and type or user's family structure, and the supervision level can strictly be formulated.
[0089] particularly, when area communication wireless module 11b receives instrument information from the instrument information transmission unit 11f of instrument information transmitter 26 transmission, the horizontal change unit 49 of the supervision of control circuit 10a determines which Gas appliance to have transmitted the operation commencing signal from by particular appliance determining unit 33; Being the time point that reduce side for the time point that increases side to fluctuations in discharge from fluctuations in discharge, by fluctuations in discharge detecting unit 34, the instant flow value of being measured by flow measurement unit 17 from this time detects; And to storage unit 47 transmission detection signals service time according to flow range.When flow increases signal by when fluctuations in discharge detecting unit 34 sends, 47 determine that the use of particular appliance begins according to storage unit service time of flow range; Storage list is changed to and the corresponding storage list of instrument information; When flow reduces information from 34 transmissions of fluctuations in discharge detecting unit, determine that the use of particular appliance stops; And storage list is reverted in the common storage list.
[0090] therefore, can be monitored the power lifetime based on the Gas appliance of the specific Gas appliance information that obtains, and should compare the time with the determined value that is higher than default supervision level, thus, based on suitable continuous service time, interior utensil monitored and can be determined the time period that needs the careful old-fashioned Gas appliance that uses to be used betwixt, and definite result can report to necessity side such as the base station, make with by forgetting that the precarious position that the long-time unusual operating position of closing Gas appliance etc. and causing accompanies can be prevented reliably.
[0091] in the above-described embodiment, wireless module 11 is based upon in the control circuit board 10 with being integrated, and this control circuit board 10 forms the controller that is incorporated in gas meter, flow meter 2.That is, wireless module 11 is incorporated in the gas meter, flow meter 2.Yet wireless module 11 does not need always to be incorporated in the gas meter, flow meter 2, and can be the type that is attached to gas meter, flow meter 2 subsequently.
