Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention discriminates whether or not a predetermined notification condition is satisfied for each of a plurality of message information to be notified to an operator, and notifies message information satisfying the notification condition by voice. The present invention relates to an informing device for a work vehicle, which is provided with a voice informing means and is configured to be powered by an engine mounted therein.

[0002]

2. Description of the Related Art An alarm device for a work vehicle having the above-mentioned structure is in a situation in which it is considered necessary for the worker to take some measures by, for example, monitoring the operation condition of each part of the work vehicle. If there is an error in the operation performed by the worker, and it is necessary to perform the operation after performing an appropriate process, etc., it is assumed that the notification condition as described above is satisfied, The voice notification means notifies the operator of the contents to be notified by audio notification of the message information satisfying the notification condition at that time from among the plurality of message information.

In such a work vehicle, conventionally, the notification volume when the message information is notified by voice is configured to be the same for each of the plurality of message information. Also, the notification volume is
Even in the case where the engine drive noise or the noise generated by the work is generated, the volume is set to be high so that the worker can hear the message information.

[0004]

However, in the above-mentioned conventional configuration, when the message information is notified, the notification is always made at a high volume. Therefore, the difference in the type of the message information and the notification timing for notifying the message information are given. Depending on the difference, etc., it may be annoying to the operator.

In addition, as the message information to be notified, for example, when the urgency is high in performing a work to warn for safety confirmation, as compared with the urgent level that is not so high, It is better to notify with a large notification volume, but if you always notify with a large notification volume even if the urgency is not so high, it may be offensive to the operator, and work on the notification volume due to the difference in the type of message information The degree of recognition of the person may differ. Further, as the message information, for example, there are information that should be notified when the engine is operating and information that should be notified when the engine is not operating. If the volume is large and low, it may be difficult to hear the message information, or if the surroundings are quiet and the volume is high, the message information may be annoying. Also by
The operator's degree of recognition of the notification volume may differ.

The present invention has been made in view of such a point, and an object thereof is to notify the message information at an appropriate volume according to the type and notification timing of the message information and the situation at that time. The point is to provide an informing device for a work vehicle that enables the above.

[0007]

According to a first aspect of the present invention, it is determined whether or not the notification condition defined for each of a plurality of message information to be notified to the worker is satisfied, and the message information satisfying the notification condition is displayed. In a notification device for a work vehicle, which is provided with a voice notification means for giving a voice notification and is configured to be powered by an engine mounted on the work vehicle, the voice notification means is provided for each of a plurality of message information. The notification volume when notifying by voice is set so that there are different sizes according to the type and notification timing of each message information, and each of the plurality of message information is set at that notification volume. Is configured to be notified.

That is, it is assumed that the notification volume when the voice notification means notifies each of a plurality of message information by voice is different in size depending on the type and notification timing of each message information. Set to. For example, a message volume that has a high degree of urgency in terms of work or that is highly important in terms of safety is set to have a higher notification volume than a message that is less urgency or level of safety In addition, the notification sound volume of the message information to be notified at the timing when the engine is activated is made higher than that of the message information to be notified at the timing when the engine is not activated. Then, the voice notification means determines whether or not the predetermined notification condition is satisfied for each of the plurality of message information, and notifies the message information satisfying the notification condition by voice. At that time, In this way, the notification is made with the notification volumes set to different sizes.

Therefore, it has become possible to provide an informing device for a work vehicle capable of announcing message information at an appropriate volume according to the type of message information and announcing timing.

According to a second aspect of the present invention, in the first aspect, the voice notification means includes, for each of the plurality of message information, engine operation message information that satisfies the notification condition when the engine is operating. , When the engine is not operating, the message volume for notifying the engine non-operation message information is divided into the engine non-operation message information that satisfies the notification condition, and the notification volume for notifying the engine non-operation message information is set as the engine operation message information. It is characterized in that the volume is set to be lower than the notification volume at the time of notification.

That is, when notifying the engine non-operation message information satisfying the notification condition when the engine is not operating, the engine operation message information satisfying the notification condition is notified when the engine is operating. As compared with the case of performing, the notification will be made at a low volume. Therefore, when the engine is operating, it is difficult for the operator to hear the message information because the noise is large due to the driving sound of the engine. Makes it easier to hear the message information. On the other hand, when the engine is not operating, the engine drive sound is not generated and it is in that quiet state. However, in such a case, the notification is made at a low volume so that the operator is less likely to feel annoyance. Therefore, a suitable means for carrying out claim 1 can be obtained.

According to a third aspect of the present invention, in the first or second aspect, the voice notification means changes and adjusts the notification sound volume while maintaining a different magnitude relationship according to the type and notification timing of the message information. It is characterized in that a manipulative volume change command means for instructing the audio notification means to change the notification sound volume is provided.

That is, by manually changing the volume of the notification volume to the voice type notification means by means of the manually operated volume change command means, the size relationship that is changed according to the type and notification timing of the message information is maintained. In this state, the notification sound volume can be changed and adjusted. To add an explanation, while maintaining the above-mentioned magnitude relationship, change and adjust so that the volume is always appropriate according to the surrounding environment such as the work situation and the difference in the listening sensitivity of the worker's sound. And a suitable means for carrying out claim 1 or 2 is obtained.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the voice notification means is capable of performing voice notification for executing the notification operation based on a command from the manually operated driving state switching means. State and a voice notification stop state for stopping the notification operation are configured to be freely switchable, and in a state in which the voice notification means is switched to the voice notification stop state, any one of the plurality of message information When the notification condition is satisfied, a display-type notification means for notifying in a display format is provided.

That is, based on a command from the manually operated driving state switching means, the voice type notification means can be switched between a voice notification possible state in which the notification operation is executed and a voice notification stop state in which the notification operation is stopped. it can. For example, when the notification sound feels unpleasant to the ear, the audio notification can be stopped by switching to the audio notification stop state. When the voice notification is stopped in this way, when the notification condition defined for the message information to be notified to the worker is satisfied, the message information satisfying the notification condition is not notified by voice. Since the notification means gives the notification in the display format, the worker can recognize the fact. Therefore,
It is also possible to notify the message information by voice when the operator switches the voice notification means to the voice notification enabled state.
There is no disadvantage that you continue to work without recognizing,
Suitable means for carrying out any of the claims 1 to 3 are obtained.

Then, if it is determined that there is a risk of overflow, that condition becomes a condition, and as the voice information for that, the voice information "fuel is full" is stored. Further, if it is determined from the detection information of the threshing sensor S5 and the engine start switch SW1 that the engine E has been accidentally started while the threshing clutch 23 is being operated, that condition becomes a condition. Is stored as voice information for “Please start the engine after disengaging the threshing clutch”.

Then, the control device 29 has different notification sound volumes for notifying each of a plurality of message information by voice, depending on the type and notification timing of each message information. Set to
The notification volume is configured to notify each of the plurality of message information. For example, as the classification according to the notification timing, for each of the plurality of message information, engine operation message information that satisfies the notification condition when the engine is operating, and engine information that satisfies the notification condition when the engine is not operating The notification volume for notifying the engine non-operation message information is set to be lower than the notification volume for notifying the engine non-operation message information. Has been done.

More specifically, as shown in FIG. 6A, four levels of volume (high, medium,
(Small, extremely small) is set, and the notification volume (high, medium) when notifying the engine non-operation message information is
The volume is set to be lower than the notification volume (small or extremely small) when the message information for engine operation is notified, and even if the message information for engine non-operation is the same, depending on the type of the message information. The notification volume is changed accordingly.

In other words, even if the engine operating message information satisfies the notification condition when the engine is operating, the volume is set to a large volume (high) for those with a high degree of urgency, and the information for messages with a low degree of urgency is set. Has set the volume a little lower (medium). Examples of the message information for operating the engine, which has a high degree of urgency, include the various clogging alarms described above. In other words, message information such as "The reaping section is clogged with straw", "The discharged straw cutter is clogged with straw", "The 2nd transport section is clogged with straw", "The tank is full of fir", etc. Is applicable. Further, as for the degree of urgency, there is information on the operation of the engine. In other words, message information such as "out of fuel" or "engine is overheated" is applicable.

Similarly, for the engine non-operation message information satisfying the above-mentioned notification condition when the engine is not operating, the volume is set a little higher (small) for those with a high degree of urgency, and For low sounds, the volume is set slightly lower (minimum). This engine non-operation message information, which has a high degree of urgency, includes, for example, the information of a voice warning in a full state that the fuel is full when refueling. As low, the operation guide information by the voice "Please start the engine after disengaging the threshing clutch" at the time of engine start is applicable.

As described above, the notification sound volume is set so that the maintenance information has different sizes depending on the notification timing and the urgency as the type of maintenance information.

Further, as shown in FIG. 5, the speaker 3
A volume adjusting operation tool 33 is provided as an artificially operated volume change instructing means for instructing change adjustment of the notification sound volume by 0, and the control device 29 operates as described above based on the change instruction of the volume adjusting operation tool 33. In addition, the notification volume can be changed and adjusted while maintaining the magnitude relationship of the volume levels set differently according to the type of each message information and the notification timing.

To add the explanation, the volume adjusting operation tool 33 is constructed so that the volume can be adjusted to three ranks, as shown in FIG.
By changing the rank as shown in, the above (large,
It is possible to change and adjust the absolute volume level while maintaining the four levels of magnitude relationship (medium, small, and extremely small). Therefore, the worker can adjust to an appropriate rank according to the work situation and preference at that time.

Further, a voice ON / OFF switch SW2 is provided as a manually operated driving state switching means, and the control device 29 is provided.
Switches to a voice notification enabled state in which the voice notification operation is performed as described above when the voice on / off switch SW2 is turned on, and enters a voice notification stop state in which the voice notification operation is not performed when the voice on / off switch SW2 is turned off. It is configured to switch. Therefore, when the operator feels that the notification by voice is troublesome, the voice on / off switch SW2 can be turned off. However, even when the voice on / off switch SW2 is off in this way,
When the determination unit 100 determines that any of the notification conditions is satisfied, the notification lamp 34, which is a display type notification unit provided in the vehicle body control unit, is turned on to notify the operator of any of the conditions. A notification is made that the notification condition is satisfied. Therefore, if the notification lamp 34 is turned on, the operator can hear the message information by voice by turning on the voice on / off switch SW2.

Next, the control of the voice notification operation by the controller 29 will be described. As shown in FIG. 7, first, it is determined whether or not the voice on / off switch SW2 is turned on (step 1). If it is turned on, it is determined whether or not a predetermined notification condition is satisfied based on the detection information of each sensor (step 2). When the notification information is satisfied and it is determined that the notification is necessary, the information of the notification volume preset according to the difference of the notification timing and the difference of the urgency as the type of maintenance information as described above, and the volume adjustment. The volume to be notified is set based on the information of the volume rank set by the operation tool 33 (step 3).
Then, the speaker 30 makes a voice notification of message information satisfying the notification condition at the set notification volume (step 4).

Also, in step 1, the voice on / off switch SW
If 2 is not turned on, it is determined whether or not the predetermined notification condition is satisfied based on the detection information of each sensor, and if it is determined that the notification information is satisfied and notification is required, the notification lamp 34 is turned on (step 5,
6). In such a lamp lighting state, the voice on / off switch S
When W2 is turned on, the process proceeds from step 1 to step 2 and subsequent steps, and steps 2 to 4 are executed to give a notification by voice. Therefore, the control device 29 and the speaker 30 determine whether or not the notification condition defined for each of the plurality of message information to be notified to the worker is satisfied, and the message information satisfying the notification condition is output by voice. A voice type notification means H for notifying is configured.
