Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a running melody sound control device as a safety device for an automatic guided vehicle.

(Prior Art) In recent years, various types of automated guided vehicles that automatically travel along guide lines have been developed, and these automated guided vehicles are equipped with various safety devices. Among these, there is a device that sounds a traveling melody to notify the approach of an automatic guided vehicle, and this type of device is also one of the main safety devices.

By the way, in conventional automatic guided vehicles, the above-mentioned running melody,
Alternatively, one melody IC is used to output abnormal alarms, etc., and is fixedly installed on the automatic guided vehicle.

Some models allow you to select the running melody, but
As shown in FIG. 2, the setting device 1 manually selects a running melody, the selected melody is stored as data in the storage device 2, and the main control device 3 outputs the melody to the melody output device 4 based on the data. The configuration was such that the data was passed as the output melody, and the melody had to be switched manually. Also, the number of melodies that could be played was small.

(Problem to be Solved by the Invention) The running melody device of an automatic guided vehicle is fixedly set as described in 1. They may become accustomed to this, and their function as a safety device to alert people when an automated guided vehicle approaches may deteriorate. Also, being forced to listen to only the same melody is bad for mental health.
It may also have a negative impact on both.

In view of the above, the present invention increases the number of melodies, and also determines a melody for warning, an abnormal alarm, a melody for notifying station arrival, etc. by setting a melody pattern using a setting device, and automatically switches between these melodies. The purpose is to be able to output various melody patterns.

[Structure of the invention]

(Means for Solving the Problems) For the above-mentioned purpose, the present invention provides a traveling melody playback device as a safety device for an automatic guided vehicle, a melody pattern setting device for setting a melody output pattern, and a melody pattern setting device for setting a melody output pattern. a melody pattern storage device for storing, a time detection device for counting the melody playing time, a melody storage device, a main control device for controlling the whole based on data from each of the devices, and outputting the melody determined by the device. A melody output device is configured.

(Function) With the above configuration, first, the melody is output by registering the melody assignment in the setting device, for example, the first song is melody #2, the second song is #4, and the switching time such as how many hours it takes to change the melody. Set the pattern. The set data is stored in the melody pattern storage device,
Based on the stored data, the main control device searches for the data of the melody to be output this time, selects the melody from the melody storage device, and gives an output command to the melody output device. When the melody switching time is set in the setting device, the time detection device starts time counting. When the count ends, the main controller switches to the next registered data. Thereafter, the same process is repeated to automatically switch and output the melody.

The melody switching is performed when the automatic guided vehicle is stopped,
When the time detection device receives time data from the main control device while counting time, the time detection device clears the count and starts counting from the beginning, and outputs from the first registered melody.

Furthermore, when the last registered song is finished, the process returns to the first song and repeats the process.

(Example) An example of the present invention will be described with reference to the block diagram shown in FIG. 1 and the flowchart shown in FIG.

Melody patterns such as allocation of a plurality of melodies to be output in sequence, setting of switching time of songs, and selection of a melody corresponding to the state of the automatic guided vehicle are registered as setting data in the melody pattern setting device W5.

The above set data is stored in the melody pattern storage device 6. This storage device is the melody pattern setting device 5.
Unless the settings are reset, back up the stored data so that it will not be lost even if the power is turned off.

Based on the above data stored in the melody pattern storage device 6, the main control device 7 controls the timing of playing and stopping, etc., and also searches the melody pattern storage device 6 for the melody data to be output this time, and stores the melody data in the melody storage device. Select a melody from 8. The above melody selection is
Assuming that the melody pattern is set in the melody pattern setting device M5 and starts from the first song, the timing of switching the melody of the second song, third song, etc. is controlled by the main control device 7. The timing of the melody switching is based on the melody switching time data set in the melody pattern setting device 5, and the time counting start is passed to the time detection device 9 when the power of the automatic guided vehicle is turned on. The time detection device 9 starts counting time. At the end of the time count, the main control device 7 is informed of the melody change, and the main control device 7 selects the next melody from the melody storage device 8. After that, the same procedure is repeated to output.

If time data is sent again from the main control device 7 while the time detection device 9 is counting the time, it is assumed that the melody pattern setting device 5 has been reset, and the data is counted from the initial state. shall be. However, this is only when the automated guided vehicle is not playing the melody. The melody selected as described above is output from the melody output device 10.

As another embodiment of the present invention, as shown in FIG. 3, in the case of a structure having a voice synthesis storage device 11 for issuing a voice warning etc., it is possible to use a normal melody storage device 8 or a voice synthesis device. Select the storage device 11.

When the voice synthesis storage device W11 is selected, only the data of the voice synthesis storage device W11 is output, and the main control device 7 only controls the timing of the sound by the voice synthesis storage device 11. A melody output device outputs the melody stored in the melody.

If no running melody is to be played, the melody pattern setting device 5 is set to have the melody E for all of the first to nth songs.

By configuring as described above, all the melody patterns set in the melody pattern setting device 5 can be easily selected.

In addition, if you decide on a melody that matches the driving state of the automatic guided vehicle, such as when there is an abnormality, when arriving at a station, when detecting a bumper, or when detecting an obstacle, you can listen to that melody and understand the current state of the automatic guided vehicle. be able to.

〔Effect of the invention〕
