[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to meter reading information of a meter (microcomputer meter) for measuring the amount of electric power, gas, water, etc. used in each household or the like, by using wireless communication at a remote location (supply side, etc.). The present invention relates to an automatic meter reading and notifying device for notifying a user.

2. Description of the Related Art Conventional techniques of this kind include, for example,
Japanese Patent Application Laid-Open No. Hei 11-22 / 2888097
There is a device described in Japanese Patent No. 5215, and in these conventional devices, a solar cell is used as a power supply of the device. In other words, using a solar cell as a power supply for the device saves energy compared to using a commercial power supply, and has the advantage that the device can be installed in a position where it is difficult to pull the wiring from the commercial power supply. It can contribute to the spread of the device.

[0003]

The advantages of providing a self-generating function such as a solar cell in the automatic meter reading and notifying device are as described above, but, on the other hand, the automatic meter reading and notifying device is compared with the case of using a commercial power supply. After the device is installed, its self-power generation function may not work properly, which may hinder the automatic meter reading notification process.
For example, when using a solar cell as a self-power generation function,
The sun was not clear when the automatic meter reading device was installed, so it was not possible to confirm the exact sunshine condition. In fact, the installation location was unfavorable for power generation by solar cells, or the However, it is possible that the sun was getting worse because a building stood in the vicinity after that. Therefore, after installation, go to the site again to check the sunshine condition, or after it is found that meter reading information is not correctly reported,
It is necessary to go to the site again to change the installation position of the automatic meter reading and notifying device.

Further, in an automatic meter reading and notifying device having a self-power generation function, the power generation function of the power generation means does not recover if the voltage of the secondary battery drops because the self-power generation function did not work well. As long as the voltage of the secondary battery remains low, there is a problem that the automatic meter reading notification process cannot be performed. The present invention has been made in view of the problem to be solved by such a conventional technology, and is an automatic meter reading and notifying device capable of confirming the power generation state of the power generation means without going to the site. It is an object of the present invention to provide an automatic meter reading notification system and an automatic meter reading notification system and an automatic meter reading notification system that can easily recover the voltage of a secondary battery whose voltage has once dropped.

[0005]

Means for Solving the Problems To achieve the above object, the invention according to claim 1 is an automatic meter reading and notifying device for reporting meter reading information of a meter to a remote place using wireless communication. An electronic circuit for performing a meter reading notification process, a secondary battery that supplies power to the electronic circuit, and a power generation unit that supplies a charging current to the secondary battery, and a power generation state of the power generation unit is reported. Power generation status reporting means.

According to a second aspect of the present invention, in the automatic meter reading and notifying device according to the first aspect of the present invention, a storage means capable of storing the power generation state a plurality of times is provided, and the power generation state notification means comprises: A plurality of times of the power generation state stored in the storage means are reported. According to a third aspect of the present invention, in the automatic meter reading and notifying device according to the first or second aspect, a plurality of supply paths capable of supplying a charging current to the secondary battery are provided, and one of the supply paths is changed to one of the supply paths. Connected to the power generation means, a connector is provided at the other end of the supply path, so that a charging current can be supplied to the secondary battery from a device different from the power generation means via the connector. did.

According to a fourth aspect of the present invention, there is provided an automatic meter reading and notifying device for reporting meter reading information of a meter to a remote place using wireless communication in order to achieve the above object. An electronic circuit for performing the operation, a secondary battery that supplies power to the electronic circuit, and a power generation unit that supplies a charging current to the secondary battery, and a supply path that can supply a charging current to the secondary battery. Are provided, one of the supply paths is connected to the power generation means, a connector is provided at the other end of the supply path, and another device different from the power generation means is provided through the connector. , A charging current can be supplied to the secondary battery.

An automatic meter reading and notifying system according to a fifth aspect of the present invention includes the automatic meter reading and notifying device according to any one of claims 1 to 3, and a host computer for collecting the meter reading information. At the same time, the host computer also receives the power generation state notified by the automatic meter reading notification device. Here, in the invention according to claim 1, since the power generation state notifying means is provided, it is possible to recognize the power generation state of the power generation means without going to the installation location of the present apparatus. As specific data of the power generation state reported by the power generation state reporting means, the value of the charging current supplied from the power generation means to the secondary battery is preferable. The value may be reported.

Further, as a power generation means applicable to the present invention, a power generation device using a solar cell, a power generation device using wind power, a power generation device using geothermal power, and the like can be considered. The timing at which the power generation state reporting means reports the power generation state may be such that the power generation state is reported immediately or at the requested time in response to a report request from the device receiving the power generation state, or may be determined in a predetermined manner. The power generation state reporting means may automatically report the power generation state when the time comes or at predetermined time intervals.

On the other hand, in the invention according to claim 2, since the storage means is provided, it is possible to report not only the instantaneous power generation state of the power generation means but also the past power generation state. For example, it is also possible to measure the power generation state of a certain day every two hours and store it in the storage means, and report data on the stored power generation state for one day (12). . Then, since the change in the power generation state per day and the maximum and minimum values of the power generation state are known, it can be more accurately determined whether or not the charging by the power generation means is performed without any problem.

Since the secondary battery can be charged via the connector, the power generation state of the power generation means is poor, and if the charging voltage of the secondary battery is lowered as it is, there is a possibility that the processing may be hindered. I can deal with it. For example, in the case where the power generation state of the power generation means is bad for a period of time (such as during the rainy season when using a solar cell), changing the arrangement position of the device does not necessarily improve the power generation state. However, it is not advisable to increase the cost of performing wiring work to supply power from a commercial power supply, so bring a portable generator or battery near the device and connect its output terminal to the connector of the device. And charging the secondary battery by the necessary power until the power generation state of the power generation means becomes favorable.

In addition, for example, when the charging current obtained by the power generation means is about half of the required value, and it is clear that sufficient charging current cannot be secured simply by changing the installation position of the power generation means, A relatively simple method of installing another power generation means to obtain half the charging current and connecting the output terminal of the other power generation means to the connector of the device so that a sufficient charging current can be obtained. Can be dealt with in a way.

[0013] Even in the invention according to claim 4, since the secondary battery can be charged via the connector, there is a possibility that the charging voltage of the secondary battery is reduced and the processing may be hindered. Can be easily dealt with. In the invention according to claim 5, the host computer can acquire both the meter reading information and the power generation state, and based on the acquired data on the power generation state,
For example, a process of notifying an operator of the power generation status of each automatic meter reading and notifying device, a process of determining an automatic meter reading and notifying device whose power generation status is defective, and a process of notifying the operator of the process, and a process of notifying the automatic meter reading and reporting device of a poor power generation status Then, it is also possible to execute processing for informing the operator of a coping method according to the degree of the defect, and the like.

More specifically, the CPU 11 recognizes meter reading information sent from the microcomputer meter 50, and the CPU 11 recognizes the meter reading information. Using the communication circuit 40, the read meter reading information is transmitted to the host computer 60 via a PHS base station on the communication circuit 41 in response to a predetermined date and time or a report request sent through the communication circuit unit 40. It is to report.

On the other hand, this automatic meter reading and notifying device 1
A power generation state notification process for notifying the host computer 60 of the power generation state of the solar cell 30 is also executed. In the power generation state notification process, the CPU 11 reads a program stored in the nonvolatile memory 11a in response to a request command transmitted from the host computer 60 via the communication line 41 and the communication circuit 40, and executes the program in the CPU 11 according to the program. In this embodiment, two types of power generation state notification processing, namely, first and second power generation state notification processing, are set.

The first power generation state notification process is a process of transmitting the charging current value and the charging voltage value at the time when the request command is transmitted to the host computer 60. That is, when the request command transmitted from the host computer 60 corresponds to the first power generation state notification process, the CPU 11

It is also possible to store in the main memory 11d in association with the current value and the charging voltage value.

FIG. 2 is a flowchart showing the outline of the power generation status notification process executed in the automatic meter reading notification device 1. Hereinafter, the operation during the execution of the power generation status notification process will be described with reference to the flowchart. That is, the power generation state notification process is executed as an interrupt process at predetermined time intervals. First, in step 101, it is determined whether a request command is input from the host computer 60, and the input of the request command is confirmed. Step 10 until done
Wait at 1. Then, when the input of the request command is confirmed, the process proceeds to step 102, and whether the content of the request command indicates the first power generation state notification process,
Judge whether it refers to the second power generation status notification processing,
When it is determined that the process refers to the first power generation state notification process, the process proceeds to step 103, where the charging current value supplied from the charging current reading circuit 17 and the charging voltage value supplied from the charging voltage reading circuit 18 are determined. Read. And step 1
In step 04, the latest charging current value and charging voltage value read in step 103 are transmitted to the host computer 60, and the processing in FIG.

On the other hand, if it is determined in the process of step 102 that the second power generation status notification process is indicated, the process proceeds to step 105 and the counter i is set to 1. Then, the process proceeds to step 106, where the charging current value supplied from the charging current reading circuit 17 and the charging voltage value supplied from the charging voltage reading circuit 18 are read, and these are stored in the charging current value storage area 11e and the charging voltage value storage area. Save to 11f.

Next, the routine proceeds to step 107, where it is determined whether or not the counter i has reached 12, and if not, the routine proceeds to step 108, where the timer is cleared and started. Then, in step 109, it is determined whether or not the elapsed time of the timer has reached 2 hours, and the process waits until the elapsed time. If the determination in step 109 becomes "YES", the process proceeds to step 110 to increment the counter i. Then, the process returns to step 106.

Then, the determination in step 107 is "YE
When "S" is reached, it is determined that 12 power generation states have been stored, and the routine proceeds to step 111. In step 111,
The process waits until an acquisition command is input from the host computer 60, and when the input of the acquisition command is confirmed, the process proceeds to step 112 and the past 24 stored in the charging current value storage area 11e and the charging voltage value storage area 11f. The charging current value and the charging voltage value over a period of time (12 times at 2 hour intervals) are transmitted to the host computer 60, and the processing of FIG.

FIG. 3 is a flowchart showing an outline of the processing in the host computer 60 which has received the charging current value and the charging voltage value as the power generation state. Hereinafter, the operation on the host computer 60 side after receiving the power generation state will be described. explain. The processing in the host computer 60 is also executed as an interrupt processing at predetermined time intervals,
First, in step 201, it is determined whether or not the power generation state has been reported from the automatic meter reading and notifying device 1, and the process stands by until the power generation state is reported. When the power generation state is notified, the process proceeds to step 202, and whether the notified power generation state is the instantaneous charging current value and charging voltage value by the first power generation state notification process, or
It is determined whether the charging current value and the charging voltage value over a 24-hour period by the power generation state notification processing described above.

If it is determined in step 202 that the charging current value and the charging voltage value are the instantaneous charging current value and charging voltage value by the first power generation state notification process, the process proceeds to step 203, where the received charging current value and charging voltage value are converted. Display on computer screen. Then, the process proceeds to step 204, where it is determined whether or not the power generation state of the solar cell 30 is extremely bad based on the charging current value and the charging voltage value. For example, an alarm such as "confirmation required" is displayed on the computer screen.

On the other hand, if it is determined in step 202 that the charge current value and the charge voltage value are obtained by the second power generation state notification process, the process proceeds to step 206, where the charge current value and the charge voltage value for 12 times are calculated. , The horizontal axis represents time, and the vertical axis represents charging current value and charging voltage value in a graph. Next, the process proceeds to step 207, where the total generated power, the instantaneous maximum and minimum values of the generated power, the average generated power, and the like are obtained from the change of the charging current value every two hours. Then, the values obtained in step 207 are displayed on the computer screen.

Further, the process proceeds to step 209, where a diagnosis on the power generation state is performed based on the values obtained in step 207, and the diagnosis result is displayed on a computer screen in step 210. As the diagnosis in step 209, first, whether or not the power generation in the solar cell 30 is performed normally is performed. If the power generation is performed normally, the diagnosis that the power is normal is immediately performed. If it is determined that there is, it is determined how much abnormality it is. Here, the determination in the case of abnormality is, for example,
"The total generated power is slightly lower than the appropriate value, but the charging voltage is sufficient, so that the processing in the automatic meter reading and notifying device 1 does not become immediately impossible", "The total generated power is significantly lower than the appropriate value." Therefore, the processing in the automatic meter reading and notifying device 1 may not be possible in a few days. " There is a possibility that it will be impossible soon. "

Then, the operator determines a countermeasure for each automatic meter reading and notifying device 1 with reference to the diagnosis result displayed on the computer screen. It is necessary to take particular measures when the power generation in the solar cell 30 is performed normally, or when the processing in the automatic meter reading notification device 1 does not immediately become impossible even if some abnormality is recognized. However, for example, when the processing in the automatic meter reading notification device 1 becomes impossible several days later or immediately, the special charging is performed in the following procedure.

This is an effective countermeasure in a case where the power generation state of the solar cell 30 is poor, but after a while, the rainy season starts and the power generation state of the solar cell 30 is recovered. On the other hand, the installation position of the solar cell 30 is often shade in the first place, and is charged by the generator 35 and temporarily stored in the secondary battery 20.
If it is clear that recharging is necessary even if the charging voltage is increased, first consider moving the solar cell 30 in the sun, and if this is possible, move the solar cell 30 Do. If it is not advisable to move the solar cell 30, another solar cell is prepared, and the power output terminal of the prepared solar cell is connected to the power control circuit 15 of the automatic meter reading and notifying device 1.
