Abstract

PURPOSE:To surely make an angler recognize a run away state of microprocessor in the case of run way of microprocessor by detecting the run way by a reset circuit at the outside of the microprocessor and resetting. CONSTITUTION:A fishing reel is provided with a microprocessor 15 to output length of fishing line drawn out from a spool on a display device. Further, a pulse generating means to output an intermittent pulse signal every time treatment of a loop of control program set in the microprocessor 15 is carried out is laid in the loop. Consequently, when the microprocessor 15 runs away, since treatment separated from the control program is done, the intermittent pulse signal by the pulse generating means is not outputted. A reset circuit R detects the phenomenon, outputs a reset signal in a reset terminal 33 so that control action of the microprocessor 15 is stopped and signal of showing the resetting is outputted to the display device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fishing reel comprising a microprocessor that outputs the length of fishing line reeled out from a spool to a display device.

[Conventional technology]

Conventionally, reels configured as described above include so-called electric reels in which the fishing line is wound by the power of an electric motor, and reels in which the fishing line is wound manually. This type of reel is also equipped with a microprocessor that processes measurement signals from a sensor that measures the amount of rotation of the spool, etc., and outputs the amount of fishing line reeled out in digital numbers on a display device such as a liquid crystal display device.

[Invention or problem to be solved]

Considering the operation of a microprocessor, this type of microprocessor operates with a low control voltage of several volts, so if static electricity is applied from the outside during operation, the microprocessor's registers may Runaway operations may occur due to phenomena such as data garbled changes in data values.

Also, when the microprocessor goes out of control, it is almost impossible to tell whether it is going out of control or not just by looking at the LCD display. If this happens, the display value may show the remaining amount of fishing line even if the fishing line has been completely reeled in. In such an uncontrolled situation, as a result of continuing reeling, the tip of the fishing rod may break off. There is room for improvement.

An object of the present invention is to rationally configure a reel that can reliably make an angler aware of the runaway state even if the microprocessor runs out of control.

[Means to solve the problem]

As mentioned at the beginning, the features of the present invention include a fishing reel equipped with a display device and a microprocessor.
Stopping the control operation by inputting a reset signal to a reset terminal of the microprocessor, and
A pulse that sets the operation of the microprocessor to output a predetermined state to the display device, and outputs an intermittent pulse signal in a loop of a control program set in the microprocessor each time the processing of this loop is performed. The method further comprises a reset circuit which is provided with a generating means and which senses that the output of the intermittent pulse signal from the pulse generating means has stopped and outputs a reset signal to the reset terminal, Its action and effects are as follows.

[For production]

When the features of the present invention are configured as shown in FIGS. 1 to 5, for example, the control program is repeatedly processed under the condition that the microprocessor (15) is operating normally, so the pulse generating means (P) outputs an intermittent pulse signal, and if the microprocessor (15) goes out of control, processing outside of the control program will be performed, so the pulse generator (P) outputs an intermittent pulse signal. No signal is output, and the reset circuit (R) outputs a reset signal to the reset terminal (33). As a result, the control operation of the microprocessor (15) is stopped, and the display device (12) is reset. A predetermined status indicating that the process has been performed is output.

In other words, in the present invention, when a runaway occurs in the microprocessor (15), the runaway can be prevented by hardware (reset circuit (R)) external to the microprocessor (15).
Since the reset is performed by sensing the reset, it is extremely reliable compared to, for example, a method in which the reset is performed by software.Furthermore, the angler can confirm that the reset has been done by using the display (
12) can be easily grasped by the display contents.

〔Effect of the invention〕

Therefore, even if the microprocessor goes out of control, the reel has been rationally constructed to ensure that the angler is aware of this out-of-control state, so that inconveniences such as breaking or damaging the tip of the fishing rod are unlikely to occur. .

Embodiments of the present invention will be described below based on the drawings.

As shown in Figures 1 to 5, the left and right side cases (
1) and (1), the guide rod (3) is driven by the screw shaft (2).
), a spool (6) for winding the fishing line (5), and a thumb rest (7) are arranged, and the left and right side cases (1), (1
) is equipped with a control case (8) between the tops of the two, and the right side case (1) is equipped with a drag operating tool (9) and a handle (1).

The control case (8) is equipped with a liquid crystal display (12) as a display device, a reset switch (13), and a set switch (14), as well as a microprocessor (15), an alarm (16), and a memory (17). , a pair of reed switches (18) and (18) are installed inside, and the left side case (1) is equipped with a subroutine (6).
A pair of reed switches (20), (20) that are operated by a plurality of magnets (19) embedded in the side surface are installed inside.

With this reel, when fishing, the fishing line (5
) is configured to output the length of the spool ( For 6), add a new fishing line (5)

That is, this tool (T) is fixed to the control case (8) by the tool body (22) by the clamp (21).
), a swinging arm (24) swingably supported around a support shaft (23) with respect to the tool body (22), and a roller (25) at the end of the swinging arm (24). A transmission system is installed inside that transmits the power from the spool (6) to the wheel (27) having the magnet (19) through a plurality of gears (26). ) on the outer surface of the fishing line (5).

roller (25) based on the action of the magnet (19).
At the same time, the reed switches (20), (20) of the side case (1) measure the rotation amount of the spool (6) based on the action of the magnet (19) of the spool (6), and various The relative data of said memory (
17).

Incidentally, at the start of this learning operation, the reset switch (
13), and when finished, press the set switch (14).
) is turned on (this control operation will not be detailed).

Then, when the learning operation is completed like this, the tool (T)
It is configured such that display operations can be performed based only on the rotation of the spool (6) with the spool (6) removed.

The configuration described above is no different from the conventional system, and the present invention detects that the microprocessor (15) goes out of control while performing a display operation, and A reset circuit (R) for resetting is provided.

In other words, the outline of the control program for the display operation set in this processor (I5) is shown in FIG. 3, and in this program, the reed switch (20),
The signal from (20) is input, the direction of rotation is determined and a count is performed, and the length of the fishing line (5) is output to the display (12) based on this count value (#l
In addition to the basic operations (steps ~#3), there is also a pulse generation routine (#4) that outputs intermittent pulse signals.

) is set to stop the display operation after displaying a predetermined pattern (steps #5 to #7).

Note that when the reset switch (13) is turned on, the processor (15) is reset by a hardware interrupt, and then the aforementioned step #6.17 is executed.

The aforementioned #4 step is one form of the pulse generating means (P), and when this #4 step is executed normally, an intermittent pulse signal is output from the output terminal (28) of the processor (15), and this Since the signal turns on and off the transistor (29) of the reset circuit (R) intermittently, the charge stored in the capacitor (30) is intermittently discharged,
As a result of maintaining the input terminal of the NAND gate (31) at the "LO" level, the output terminal of the other NAND gate (31) is maintained at the "LO" level, and if the display operation goes out of control, # Since step 4 is no longer executed, the intermittent pulse signal from the output terminal (28) of the processor (15) is not output, and the transistor (29)
remains in the OFF state, and the charge on the capacitor (30) increases, causing the input terminal of the NAND gate (31) to become rHi.
As a result of switching to J level, the other NAND game) (
Since the output terminal of 31) is switched to the rHiJ level, the rHiJ level signal as a reset signal is input to the reset terminal (33) which is electrically connected to this output terminal, and as mentioned above, a predetermined pattern is output to the display (12). This makes the fisherman aware that the processor (15) has run out of control.

Note that when a reset signal is input to this reset terminal (33), the display operation is forcibly stopped by a hardware interrupt, similar to when the reset switch (13) is operated.

Incidentally, this control system uses a power supply circuit (34) with a battery.
It is configured so that power is supplied from the
