Description

Backup system for electric reel {BACKUP SYSTEM FOR ELECTRIC FISHING REEL}

The present invention relates to a backup system for electric reels.

In electric reels, it is known that a display unit that displays water depth information of a tool mounted on the tip of the fishing line is installed. Inside the electric reel, a control unit containing a microcomputer is installed. The control unit controls the motor of the electric reel, calculates the water depth of the tool from spool rotation data, and displays the water depth information on the display. . Power is supplied to the control unit of the electric reel through a power cord connected to an external power source.

In such electric reels, the power cord may become disconnected from the external power source for some reason, cutting off the power supply from the external power source to the control unit. When the power supply to the control unit is cut off and the control unit's microcomputer is reset, the water depth information calculated by the microcomputer is also reset. Therefore, there is a risk that the water depth information displayed on the display may not be accurate when the power cord is reconnected.

So, in order to solve the above problem, Patent Document 1 discloses a configuration in which a backup power source such as a condenser is installed inside the electric reel, and power is supplied from the backup power source when the power supply from the external power source is cut off. Therefore, when power supply from an external power source is resumed, the water depth information before power was cut off is taken over and the received water depth information is displayed on the display unit.

Japanese Patent Publication No. 2000-175603

In such an electric reel, in order to avoid resetting the microcomputer in the control unit, the microcomputer is placed in a standby state to realize backup of water depth information, etc. Therefore, while the microcomputer transitions from the normal state to the standby state, it is necessary to supply current in the normal state to the microcomputer from a backup power supply. However, in order for the backup power supply to accommodate the normal consumption current of the microcomputer, there is a risk that the backup power supply will have to be large.

The object of the present invention is to realize backup of water depth information, etc. while suppressing the enlargement of the backup power supply.

The electric reel backup system according to one aspect of the present invention includes a control unit, a memory unit, a time measurement unit, and a backup power source. The control unit controls the electric reel using power supplied from an external power source. The storage unit stores control information regarding control of the electric reel. The time measuring unit measures the power cut-off time from power supply cut off from the external power source to resumption of power supply from the external power source. The backup power source operates the time measuring unit at least while the power supply from the external power source is cut off. The control unit controls the electric reel based on the control information stored in the storage unit when the power cut time is within a predetermined range, and discards the control information stored in the memory unit when the power cut time exceeds the predetermined range.

In this electric reel backup system, after cutting off the power supply from the external power source, there is no need to supply current in the normal state from the backup power source to the control unit and put the control unit in a standby state. As a result, a backup power supply with a small capacity can be used for the electric reel, making it possible to miniaturize the backup power supply. In addition, by installing a time measuring unit, it becomes possible to control the backup time, and it becomes easy to determine whether the backup power is lost when the power supply is resumed from the external power source after cutting off the power supply from the external power source. . Therefore, it is possible to accurately determine whether to execute backup processing.

Preferably, the time measuring unit has a real-time clock and measures the power cut-off time based on time information when power supply from the external power source is cut off and time information when power supply from the external power source is resumed. In this case, since the real-time clock circuit power consumption is small, a backup power supply with a small capacity can be used. Additionally, the backup time can be controlled with high precision using a real-time clock.

Preferably, the storage unit is a volatile memory, and the backup power supply supplies power to the storage unit when the external power source is cut off. In this case, if the backup power supply is lost, the data stored in the storage unit is also reset, so there is no need to destroy the data stored in the storage unit when the backup process is determined to be unnecessary.

Preferably, the backup power source is a condenser. In this case, there is no need to supply normal current to the control unit from the backup power supply after cutting off the power supply from the external power source, thereby putting the control unit in a standby state. As a result, a small condenser can be used as a backup power source, making it possible to miniaturize the backup power source.

Preferably, the device further includes a water depth display unit that displays water depth information regarding the water depth of the tool, and the control unit further includes a display control unit that displays water depth information on the water depth display unit. The control information stored in the storage unit includes water depth information, and the display control unit displays the water depth information stored in the storage unit on the water depth display unit when the power cut time is within a predetermined range. In this case, if the power cut-off time is within a predetermined range, the water depth information stored before the power supply from the external power source is cut off is displayed on the water depth display unit, so fishing can be carried out while maintaining accurate water depth information.

According to the present invention, in a backup system for an electric reel, backup of water depth information, etc. can be realized while suppressing the enlargement of the backup power supply.

The shift lever 14 is a member for adjusting the output of the motor 8, and the output of the motor 8 changes depending on the swing position of the shift lever 14. The clutch operating member 15 is a member for performing a clutch operation that turns on and off the drive transmission of the handle 3, the motor 8, and the spool 2.

The counter case 5 is fixed to the front upper part of the reel body 1. A display portion 16 having a liquid crystal display is installed on the upper surface of the counter case 5. The display unit 16 has a water depth display unit 16a that displays water depth information regarding the water depth of the tool.

As shown enlarged in FIG. 2, the water depth display unit 16a includes a water depth display area 16b that displays the water depth of the tool, a fish habitat memo display area 16c that displays the location of the fish habitat layer, and a water bottom. It has a bottom memo display area 16d that displays , and a singular display area 16e that displays the position of the shift lever 14 in singular numbers. In the water depth display unit 16a, the length of the line delivered from the electric reel 100 is calculated based on, for example, the rotational speed and diameter of the spool 2, and the calculated value is displayed. Additionally, the water depth information displayed on the water depth display unit 16a may be the distance to the tool based on the water surface or the distance to the tool based on the bottom of the spoon.

On the rear side of the display unit 16, a plurality of switch operation units 17 are provided for changing the control state or making various settings. Inside the counter case 5, a control unit 21 that controls the electric reel 100 is accommodated (see Fig. 3).

The control unit 21 controls the electric reel 100 using power supplied from an external power source (PS). The control unit 21 has a microcomputer including a CPU with an arithmetic function, RAM, ROM, I/O interface, etc. As shown in FIG. 3, the control unit 21 has a motor control unit 21a that PWM controls the motor 8, and a display control unit 21b that displays information about the water depth of the tool on the water depth display unit 16a. there is.

Additionally, a shift lever 14, a switch operation unit 17, a spool sensor 22, and a spool counter 23 are connected to the control unit 21. Additionally, the control unit 21 is connected to a display unit 16, a motor drive circuit 24, a storage unit 25, a time measurement unit 26, and a backup power supply 27.

The spool sensor 22 is composed of two reed switches arranged side by side, front and rear, and detects the rotation direction of the spool 2 depending on which reed switch emits a detection pulse first. Additionally, the spool sensor 22 detects the rotation speed of the spool 2 using a detection pulse. The spool counter 23 is a counter that counts detection pulses, and rotation data of the spool 2 can be obtained from the counted value. The line length is calculated based on this rotation data, and information about the water depth is displayed on the water depth display unit 16a according to the calculated value.

The motor drive circuit 24 PWM drives the motor 8. The duty ratio of the motor drive circuit 24 is controlled by the control unit 21. The control unit 21 controls the motor 8 in either a constant speed mode or a constant tension mode.

The storage unit 25 is composed of non-volatile memory such as ROM or flash memory. The storage unit 25 stores information regarding the control information of the electric reel 100, including water depth information regarding the water depth of the tool displayed on the water depth display unit 16a. Here, information regarding control information may include, for example, control information such as the display mode of the water depth display unit 16a or the control mode of the motor 8. Additionally, in the storage unit 25, time information at the time of storing information regarding the control information of the electric reel 100 is stored based on the time measured by the time measurement unit 26, which will be described later.

The time measuring unit 26 measures the power cut-off time T until power supply is resumed from the external power source PS to the control unit 21 after power supply is cut off from the external power source PS to the control unit 21 . In this embodiment, the time measurement unit 26 has a real time clock (RTC) 26a that measures the time. When the power supply from the external power source (PS) to the control unit 21 is cut off, the time measuring unit 26 continues to measure the time using power supplied from the backup power supply 27.

The backup power supply 27 is a condenser in this embodiment, and an electric double layer capacitor is used. The backup power supply 27 supplies power to the time measuring unit 26 and operates the time measuring unit 26 at least while the power supply from the external power supply PS to the control unit 21 is cut off. In this embodiment, while power is supplied to the control unit 21 from the external power supply PS, power is supplied to the time measuring unit 26 from the external power supply PS. And, during this time, the backup power source 27 is charged with the external power source PS. In addition, even while power is being supplied to the control unit 21 from the external power source (PS), the time measuring unit 26 can be configured to operate by supplying power to the time measuring unit 26 from the backup power supply 27.

[About backup processing]

Next, the flow of the backup processing of the control unit 21 will be described with reference to the flow chart in FIG. 4. Here, water depth information regarding the water depth of the tool is explained as an example of control information regarding control of the electric reel 100.

In step S1, when the electric reel 100 is started, the time measuring unit 26 starts measuring the time. At this time, power is supplied to the control unit 21 from the external power supply PS. And, when the electric reel 100 is started and the time measuring unit 26 is measuring the time using the power supplied from the backup power supply 27, the time measuring unit 26 takes over the time information and sets the time. Measure.

In step S2, the water depth information is stored in the storage unit 25. Storage of the water depth information in the storage unit 25 is performed periodically while power is supplied from the external power supply PS, and the storage information is updated each time. The timing for storing the water depth information is, for example, every predetermined time, each time the water depth information changes, or when the switch operation unit 17 is operated. Additionally, in step S2, the memory time T1 when the water depth information is stored is stored in the storage unit 25 based on the time measured by the time measurement unit 26.

In step S3, it is determined whether the power supply from the external power source PS to the control unit 21 is cut off. If it is determined that the power supply from the external power source (PS) to the control unit 21 is not cut off, the backup processing is not executed. If it is determined that the power supply from the external power source (PS) to the control unit 21 is cut off, the process moves to step S4.

In step S4, power is supplied from the backup power source 27 only to the time measuring unit 26. Accordingly, the time measuring unit 26 continues to measure the time even after the power supply from the external power source PS to the control unit 21 is cut off.

In step S5, it is determined whether power supply to the control unit 21 has been resumed from the external power source PS. If it is determined that power supply to the control unit 21 from the external power source PS has been resumed, the process moves to step S6. In other words, when power is supplied to the control unit 21 from the external power source PS, the process moves to step S6. If the power supply from the external power supply (PS) to the control unit 21 is not resumed, the backup processing is not executed.

In step S6, first, the restart time T2 when power supply from the external power source PS to the control unit 21 is resumed is determined based on the time measured by the time measuring unit 26. Then, the power cut time T until power supply from the external power source PS is resumed after power supply is cut off from the external power source PS is calculated from the difference between the storage time T1 and the restart time T2. Here, the storage time T1 is regarded as time information at the time of power cutoff, and the power cutoff time T is calculated.

In step S7, it is determined whether the power cut-off time T calculated in step S6 is within a predetermined range. If it is determined that the power cut-off time T is within the predetermined range, the process proceeds to step S8. Here, the predetermined range is, for example, 6 hours. In step S8, the water depth information stored in step S2 is displayed on the water depth display unit 16a, and the electric reel 100 is controlled based on the water depth information stored in step S2. That is, the backup processing is executed here.

If it is determined in step S7 that the power cut time T exceeds the predetermined range, the process proceeds to step S9. In step S9, the water depth information stored in step S2 is discarded. In addition, even when the time data measured by the time measuring unit 26 is initialized, that is, when the power supply from the external power source (PS) to the control unit 21 is cut off for a long time and the backup power source 27 is lost, It is considered that more time has elapsed than necessary, and the water depth information stored in step S2 is discarded.

By performing the above backup processing, the following effects can be obtained. First, the real-time clock 26a has low circuit power consumption, and in step S4, power is supplied only to the time measurement unit 26 from the backup power supply 27. As a result, an electric double layer capacitor with a small capacity can be used in the backup power source 27, making it possible to miniaturize the backup power source 27.

Also, generally, an electric double layer capacitor with a large internal resistance has a smaller volume compared to an electric double layer capacitor with a small internal resistance. In this embodiment, when the power supply from the external power supply (PS) to the control unit 21 is cut off, power is not supplied to the control unit 21 from the backup power supply 27, so an electric double layer capacitor with a large internal resistance is used as the backup power supply. It can be used as (27). That is, a small electric double layer capacitor can be used as the backup power source 27.

Additionally, by using the real-time clock 26a as the time measuring unit 26, even when a double-layer capacitor is used as the backup power source 27, the time span until the backup power source 27 is lost varies depending on the environment such as temperature conditions. There is no significant change due to differences in the environment or individual differences. Therefore, the backup time can be controlled with high precision. Additionally, if the power supply from the external power source (PS) to the control unit 21 is cut off for a long time and the backup power source 27 is lost, the time measured by the time measuring unit 26 is initialized. Therefore, when the power supply to the control unit 21 is resumed after the power supply to the control unit 21 has been cut off, it is easy to determine whether the backup power source 27 is lost, so it is possible to determine whether to perform backup processing. You can make accurate judgments.
