Noh. The lamp 21 is usually easy to see from the driver's seat.
Due to lack of battery capacity because it is installed in a place
Malfunctions can be prevented beforehand. Next, the battery capacity detecting means 3 and the transmission
The method will be described with reference to FIGS. battery
The residual capacity corresponds to the normal usage time as shown in FIG.
Decrease. For example, if the battery capacity detecting means 3
When the current is detected as A, the remote control
6 inputs this A, finds the difference to the alarm level C,
One switch operation and signal
Operable by dividing by the power used for signal transmission
Convert to time or count. For example, calculate the number of operable times
Suppose that the result is 5000. Following this, following the switch operation information signal,
The remaining battery capacity information is output to the transmission circuit. An example
For example, both information is 9 bits with 1 start bit
Assuming that the data has a data structure, the transmission signal as shown in FIG.
Become. When the display / alarm 21 is a digital display device,
It can be configured as the signal a. The first 9 bits of the signal are
This includes the key identification code in the switch operation information.
And On the other hand, the remaining battery capacity information is the last 9 bits
It is represented by The remaining battery capacity of A is 5000
First, divide by 32 to shorten the data length
156, which is then converted to hexadecimal to obtain 9C.
End data. Therefore, 2, 5, 6, 7 bits are
It becomes "1" (H) level. The first bit starts
Is a bit that indicates Here, when the display / alarm 21 is a lamp
First divides the display into ranges every 3000 times,
0 or more, 6000 to 9000, 3000 to 6000, 3
Divide into 4 blocks of less than 000. Next, the calculation result 500
From 0, this A becomes the third block, for example, 4 bits
Is set to “1”, a configuration like the signal b can be performed. Also figure
When B of 2 is detected, the result 1000
Let's say When the transmission signal has the same configuration as the signal b,
In this case, 5 bits per block becomes "1" in the fourth block.
Signal c. In addition, if C in FIG.
3 and 6 of the signal d in FIG.
I do. Transmission is performed in the format described above.
When the in-vehicle device 10 receives the message, the display / alarm unit 21
Activated the lamp according to a predetermined pattern
For vehicles with a display device, the information is displayed graphically or
The digital display allows the user to
Can be notified of the available remaining capacity of the tree. A in FIG.
In this regard, when the signal b in FIG. 3 is input to the in-vehicle device 10,
The in-vehicle device control unit 13 receives the switch operation information from the received signal b.
Information and battery capacity information are separated and then
Read the remaining battery capacity information except the start bit
To recognize that the third bit is 1. After receiving this
Display on the lamp 21 with the lighting time longer than the light-off time.
Output to the second I / F circuit. Also at point B
Lighting time shorter than point A is displayed and displayed to the user.
The remaining battery level of the
I can make them understand more. When the transmission signal reaches point C in FIG.
When the signal d in FIG. 3 is received, the control of the lamp is changed,
Early control allows users to better understand
Enhance. When the remote control operation limit of point D is reached,
Change control to light mode. Thus, the usable range
Change the display method to notify the user
It is possible to help the knowledge and notice of low battery capacity
Knowledge can be assured. Here, point C in FIG.
Information level, and the remaining battery capacity is below a predetermined value.
And the remote control device 1 determines that
Is recognized and the display or alarm method is changed. The figure
Either the remote controller 1 or the on-vehicle device 10 below the point C of 2
The determination may be made easily. Display and alarm
21 is output for a predetermined time continuously.
Or by periodically outputting at predetermined intervals,
