Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention is a residential information system that transmits data regarding usage of gas, electricity, water, etc. to a management center via a telephone line. Regarding transmission 1G device.

[Prior Art] Conventionally, this type of device inputs information such as meter reading information that detects gas usage periods, security information of gas leak sensors, supporting equipment, etc., and automatically transmits the information to a management center.

They also rectified and smoothed the 100-volt commercial alternating current that was distributed to homes, or used primary batteries to operate electrical circuits in residential information transmitting devices.

[Problems to be Solved by the Invention] However, for example, when this residential information transmitting device is used for central meter reading at a management center of a restaurant, etc. Bu[
When one pan gas cylinder is replaced, it is necessary to reset the negative count information, and this reset usually requires an information reset means manually operated by a worker. Further, when this residential information transmitting device is used for centralized city gas meter reading, such a reset operation is not necessary, but it is convenient to have a manual operation switch that can notify the management center of emergencies. Furthermore, a residential information transmitter that uses 100 volt commercial AC current as a power source requires a DC circuit to convert AC to DC, a filter to smooth pulse components, and a regulator to stabilize the voltage. In addition, since an outlet, a cord, a fuse, etc. are required to connect the residential information transmitting device to a commercial AC power source, there is a problem in that the manufacturing cost increases.

In addition, for residential information transmitting devices that use primary batteries as a power source, if the widely used manganese batteries are used as primary batteries, the usable period of the manganese batteries is short, so they must be replaced frequently. However, if a long-life lithium battery is used as the primary battery, lithium batteries are expensive, so if a lithium battery is used to obtain the operating voltage of the device, the primary battery will be very expensive. I was at 1.

The present invention has been made in view of the above circumstances, and its purpose is to provide a residential information transmitting device with a manual operation input port that can be used for multiple purposes, such as resetting meter reading information including charge and negative counts. The purpose of the present invention is to provide a residential information transmitting device that can keep the cost of power supply low.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an electric circuit that detects the usage of gas, electricity, water, etc., and transmits the usage information to a management center via a telephone line. In the residential information transmitting device, the electrical circuit includes at least one manual operation input port, and a power supply unit including a secondary battery charged by electricity supplied from the telephone line; The technical means is to operate the electric circuit using electricity charged in the secondary battery.

[Operations and Effects of the Invention] The present invention having the above configuration is equipped with an FA operation input boat, so when this system is used for meter reading of propane gas, a cylinder reset switch can be connected, and this reset switch can be used to perform treeline negative counting. The meter reading information of old gas cylinders can be reset, and when used for city gas meter reading, the manually operated boat can be used as a service boat for emergency contact to the management center. This allows the same system to be used in both propane gas and city gas use areas, and has the advantage that if a propane gas use area is converted to city gas, the system can be used as is. Furthermore, the secondary battery is charged with the electricity supplied from the telephone line, and the electricity charged in the secondary battery is used to operate the electric circuit. The price of the power source can be kept low compared to when using secondary batteries.

Furthermore, since the secondary battery is charged and used, there is no need to replace the secondary battery over a long period of time, making maintenance easy.

[Example] Next, a residential information transmitting device of the present invention will be described based on an example shown in the drawings.

The pulse generating meter N1, for example, places a saltpeter f1 on the rotating body of a gas δ1 suspension meter (not shown) that rotates in proportion to the gas flow rate, and generates a pulse by touching a reed switch with the magnetic force of the corner stone. It is something.

The reset switch N2 is, for example, a push button switch, and is operated by a person replacing the gas cylinder when replacing the gas cylinder. Through this operation, the meter reading information between the gas usage periods for the old cylinder, which was counted as a product/negative, is discarded, and the product/negative count for the new cylinder is set.

The voltage of the dial signal generation circuit 7 to be used, the microphone processor (CPLJ) 8, the power supply section 9 of these, the primary battery 10 as a backup power supply, and the power supply section 9 is set to the first set voltage ( Primary battery control circuit 1 that supplies power from the primary battery 10 to the electric circuit 1 when the voltage drops below 3 volts (for example, 3 volts)
1 and the voltage of the primary battery 1o is set to the second set voltage (for example, 2
．． 6 volts).

The circuit switching relay 5 has relay contacts 5a and 5b, and switches the telephone line network between the telephone T and the electric circuit 1.

The dial signal generating circuit 7 is a device that generates a signal for selecting a called name (management center) to an automatic exchange in the telephone line network, and also generates a signal for transmitting information to the computer C. , a button signal is generated by combining one frequency each from two frequency groups, high group and low group, within the audio band.

The microprocessor 8 inputs the overall system control procedure, the Coser code, the date and time of automatic meter reading, and the call signal of the gas supply company's Combita C connected to the telephone line (
the telephone number of the telephone connected to computer C), the set value of the gas outflow rate (for example, a value that corresponds to 70% of the amount of gas used in a gas cylinder, and a value that corresponds to 85% of the amount of gas used between gas cylinders), etc. It performs functions such as storing and counting the number of pulses sent from the pulse transmitting meter N1, and is equipped with an internal timer.

The settings of the automatic meter reading start date and time, knee day code, call signal of computer C, gas out flow rate setting value, and initial value of the gas meter specialized for masonry, which are stored in this microb [l sensor 8], are stored in this house. This is set by a worker or the like when the information transmitting device A is installed at home.

Telephone line m1 currently used in Japan. From, 1
By interposing a resistor with a mega ohm or more, 48
Volt, 48 microphones [capable of obtaining 1 amp of power. However, it is difficult to operate the electric circuit 1 with this electric power.

For this reason, the power supply unit 9 of the present invention includes a secondary battery 9b that is always connected to the telephone line network through a paper core 9a of 1.1 megaohm, and the electric current supplied by the telephone line network is provided. For example, it is provided to charge a secondary battery 9b having a rated voltage of 3.6 volts. These two power transmission i
T! ! As the battery 9b, a nickel cadmium battery, an alkaline battery, a sodium sulfur battery, an alkaline manganese battery, etc. are used. Power is supplied to the circuit switching relay 5, the center signal detection circuit 6, the dial signal generation circuit 7, and the microprocessor 8 in the electric circuit 1 using the charged power stored in the secondary battery 9b.

Further, the primary battery 10 is connected in parallel with the secondary battery 9b of the power supply unit 9. This primary battery 10 has a rated voltage of, for example, 3.
It is set to 0 volts, and when the voltage of the secondary battery 9b drops to 3 volts or less, the primary battery control circuit 11 is activated to supply power to the electric circuit 1. In this embodiment, a lithium battery with a long life and easy maintenance is used as the primary battery 10.

The battery depletion detection circuit 12 detects when the voltage of the primary battery 10 drops below a second set voltage of 2.6 volts (set by the voltage of the IL-sensor 8). This is what generates the old appearance.

FIG. 3 shows a block diagram of the functions of the microprocessor 8 to detect when it is time to replace a gas cylinder, the automatic meter reading function, the function to detect when the primary battery 10 is dead, and the function to report a gas leak.

The automatic side function includes a gas usage area calculation process 811 that counts the number of pulses output by the pulse transmitting meter N1 and determines when to use the gas based on the counted number. The total amount of gas used during gas usage calculated by the gas usage data fraud process 811 is accumulated in a total accumulation process 812. On the other hand, the date and time set in the meter reading date and time setting section 813 and the date and time counted by the timer 814 are compared in a meter reading date and time detection process 815, and the date and time when the timer 814 clicks 1 is set in the meter reading date and time setting section 813. When it reaches
The accumulated numerical value in the total accumulation process 812 is encoded in the gas usage encoding process 816, and is reported to the computer C of the gas supply company in the transmission process 800.

The gas cylinder replacement timing detection function calculates the cumulative time t1 between gas uses after reset by trip cumulative processing 821, which is set (reset) to the initial If value by the rising trigger when the reset switch N2 is turned on. The numerical value accumulated in this trip accumulation 1 processing 821 is compared with the numerical value corresponding to 70% usage of gas stored in the first gas out setting section 822, and as a result, the accumulated value in the trip accumulation processing 821 is The value h is the first gas out setting section 82.
If it is determined that the value is 6 larger than the stored value of 2, the first comparison process 823 generates a first 'P1 information signal. Further, the cumulative value in the trip cumulative processing 821 is compared with the corresponding numerical value of 1 during the 85% usage of gas stored in the second gas out setting section 824, and as a result, the cumulative value in the trip cumulative processing 821 is The value below 31 is the second gas out setting part 8.
If it is determined that the number is larger than the number stored in 24, the second
The comparison process 825 generates a second alarm signal.

If the first comparison process 823 generates a first alarm signal,
A first gas out encoding process 826 encodes that the remaining amount in the gas cylinder is 30%, and a transmission process 800 reports this to the viewer C of the gas supply association. Further, if the second comparison process 825 generates a second alarm signal, the second gas out encoding process I! i! In step 827, the date when the remaining amount in the gas cylinder is 15% is encoded, and the transmission processing is performed in step 800.
This notification is sent to computer C of the gas supply company.

The battery depletion detection function of the primary battery IQa is
When the voltage of a drops below the dead battery voltage value (2,5pol 1-), the dead battery detection circuit 12 outputs the old signal to the microprocessor 8, and the dead battery encoding process 831 detects the voltage of the primary battery 10a. It encodes that the voltage has dropped below 1.5 volts and transmits it to the transmitter 1! I! 800 to notify computer C of the gas supply trial.

The gas leak reporting function is such that when the gas leak sensor N3 detects a gas leak, a gas leak encoding process 841 encodes the fact that a gas leak has been detected, and a transmission process 800 notifies the computer C of the gas supply manager.゜Next, during automatic meter reading, when reporting the time to replace the gas cylinder, 1
Transmission processing 8 in the Micro 10 Resosa 8 when reporting that the primary battery 10a has run out and when reporting a gas leak
The operation of 00 will be explained based on the flowchart shown in FIG.

First, the line use detection circuit 3 determines whether or not the lower part of the telephone is in a call (Sl), and if the phone is in a call, repeats (Sl). Also, when the call is not in progress, the call & detection circuit 4 determines whether or not the @ call is in progress (S2).
, while calling, repeats from (Sl). Also, in the old model when the call is not in progress, the circuit switching relay 5 disconnects the telephone from the telephone line network, and connects the telephone line to the microphone [1 and the processor 8 (circuit closing).
(83).

Next, it is determined whether 3 seconds have elapsed since the circuit was closed (S4), and if 3 seconds have not elapsed, the process (S4) is repeated. When 3 seconds have elapsed since the circuit was closed, the dial signal generating circuit 7 activates the gas supply connection computer C.
t, = automatic dialing (S5), and it is determined whether a response signal from the destination side has been received by the center signal detection circuit 6 (S6). 11'i, which received the response signal, transmits r-C information according to each regulation of transmission control (S7),
It is determined whether the center communication detection circuit 6 has received a retransmission request signal from the destination side (S8). If a retransmission request signal is not received, it is determined whether 3 seconds have passed since the end of information transmission (S9), and if no retransmission request signal has been received (
Return to Ma (S8). If 3 seconds have passed after the transmission ends,
The circuit switching relay 5 connects the telephone IT and the telephone line network, and the telephone line network and the Micro 10 Retuna 8 are disconnected (810), and the process ends.

If no response signal is received from the destination side in (S6),
It is determined whether 15 seconds have elapsed since the automatic dialing of the destination (S11), and if 15 seconds have not elapsed, the process returns to (S6). In addition, when 15 seconds have elapsed since automatic dialing was performed, or when a retransmission request signal is received in step S8), the line is released (812), and then it is determined whether or not automatic dialing has been performed three or more times. (S13).

If the number of calls is less than 3, it is determined whether 5 seconds have passed since the line was opened (814), and if 5 seconds have not passed, repeat (814), and if 5 seconds have passed, then returns to (Sl) again.

If it is determined in (S13) that the automatic dialing has been made 3 or more times, it is determined whether or not the automatic dialing has been made 9 times (815), and if the automatic dialing has been made 9 times, the process ends. However, if the number of times is less than 9, it is determined whether 5 minutes have passed since the line was released (816
), if 5 minutes have not passed, repeat (816),
If 5 minutes have passed, return to (Sl) again.

During automatic meter reading as described above, when reporting that it is time to replace a gas cylinder, when reporting that the primary battery 10 is dead, and when reporting a gas leak, the circuit switching relay 5 in the electric circuit 1, the center signal detection circuit 6, the die Since the 8 full signal generation circuit 7 and the microb [l series 8 operate 4 times, the secondary of the power supply section 9 is connected to the pond 9.
The power charged in b is consumed.

However, automatic meter reading is performed only once a month, and notifications of gas cylinder replacement time, notifications of dead primary battery 10, and notifications of gas leaks are not performed many times a month. Therefore, the secondary battery 9b of the power supply section 9 is constantly charged by the telephone network and maintained at 3.6 volts.

Furthermore, even when the microprocessor 8 is not transmitting information to the computer C of the gas supply company, it counts the number of pulses of the timer and the meter N1 with pulse transmission, but the current consumption of the timer is 1 microampere or less, and the number of pulses is The current consumption when counting is 2 to 3 microphones [
1 ampere, the secondary battery 9b of the power supply unit 9 has y of the power supplied by the telephone network rather than the power consumed.
) is charged significantly.

As described above, the present invention charges the secondary battery 9b of the power supply unit 9 with the power supplied from the telephone line network, and operates the electric circuit 1 using the power charged in the secondary battery 9b. Therefore, the cost of the power source can be kept low compared to when a conventional commercial AC power source is used as the power source or when a primary battery is used as the main power source. In addition, the secondary battery 9
In order to charge and use the power supply unit 9 for a long period of time,
Maintenance is easy because there is no need to replace the secondary battery 9b.

On the other hand, information is transmitted to the computer C of the gas supply company many times, and the power of the second snowstorm 11jj9b of the power supply section 9 cannot keep up with charging, and the voltage of the secondary battery 9b is lower than the first set voltage (
For example, when the voltage drops below 3 volts), when the power supply section 9 breaks down, or when the telephone line network is disconnected for a long period of time and the secondary battery 9b of the power supply section 9 is not charged. Also, since the electric circuit 1 receives power from the primary battery 10, the system can be operated and the data stored in the Micro 10 Retsusa 8 can be retained for a long period of time. , it is possible to eliminate various confusions caused by erasing data.

Further, the primary battery 10 is such that the secondary battery 9b of the power supply section 9 is the first battery.
The primary battery 10 is not used until it drops below the set voltage, and even if it is used, the voltage of the secondary battery is charged again by the telephone line 1 and becomes the voltage, so the frequency of use of the primary battery 10 is very low.
The life of the primary battery 10 can be significantly extended. By using a lithium battery as the primary battery 10, the life of the single blow mold piece 10 can be further extended1.Furthermore, since the voltage of the primary battery 10 may be lower than the voltage of the power supply unit 9, Even if an expensive lithium battery is used as the primary battery 10, the damage caused by tJ manufacturing can be kept low compared to conventional power supplies that use lithium batteries.

(Modified example) In this embodiment, a reset switch for the load/minus count information of used items of old gas cylinders is connected to the manual operation input port, but instead of this, for example, if this system is used for city gas meter reading, Since the reset itself is not necessary, by attaching a manual switch to this input port, it can be used as it is as a boat for emergency communication to the management center.
