JPS6229445A - Abnormarity detecting device for farm machine or the like - Google Patents

Abstract

PURPOSE:To make it easy to take a countermeasure to an abnormal condition, by detecting the abnormal condition produced in some operational parts of a farm machine or the like, and giving an alarm depending on the detected data through an alarm buzzer and an audio monitor until a stop switch is pushed. CONSTITUTION:In a farming work using a farm machine or the like, an abnormal condition is detected by sensors 18 to 20 furnished at the driving machine, cultivating machine, threshing machine, and the like attached thereto, and the signal is transmitted to an abnormarity detecting unit 15 arranged on the dash board. As a result, while an alarm lamp is blinked responding to the abnormal point, the signal is transmitted to a relay 23, a contact 25 is on, and an alarm buzzer 2 is operated. Then after the contact 26 is off through a timer 24, or the operator cuts off the main switch 22, the other contact 27 of the timer 24 is on to operate an audio monitor 3, which pronounces the content of the abnormal condition through a speaker 17. After that, the audio monitor 3 and the speaker 17 is stopped through a relay 28 when the operator pushes the stop switch 4.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an abnormality detection device for agricultural working machines and the like, and can be used to prevent trouble during one operation.

Prior Art and Problems to be Solved by the Invention Recently, abnormality detection devices for agricultural machinery and the like have been studied in order to completely prevent troubles from occurring during work. 'r: The technology for using the abnormality detection device described in layer 1 and 7 is still at the stage of trial and error and has not yet become established in the market.

Therefore, it is an object of the present invention to provide an abnormality detection device that can be used most effectively by these workers.

Means for Solving the Problems This invention provides an alarm (2) and a voice monitor (3) etc. that are activated simultaneously by a sensor (1) that detects an abnormality in a machine or mechanical action, and Only the alarm (2) is stopped, and the sound monitor (3) is turned off by pressing the sound stop switch (
4) An abnormality detection device for an agricultural machine or the like is configured to remain in a continuous state until it is turned off.

Functions and Effects of the Invention Abnormalities that occur in each working part of an agricultural machine, etc. due to the machine or mechanical action are detected in advance by sensors (1) installed in each working part, and the abnormality detection device first sounds an alarm (
2) to alert the worker, and at the same time, the voice monitor (3) indicates the location of the abnormality, how to deal with it, and
The cause and other reasons are explained, but at this time, after the alarm (2) has alerted the worker, it may interfere with the explanation of the sound monitor (3) to the worker, or it may not activate. If the time is too long, it may cause discomfort to the worker, so in order to avoid continuous operation for an indefinite period of time, for example, as soon as an abnormality is detected in the sensor (1), a timer etc. is used to operate the sensor (1) for a few seconds and then automatically stop the operation. On the other hand, the voice monitor (3) is explained repeatedly until the worker is satisfied, and then the voice monitor (3) is stopped by the voice stop switch (4) by a worker, and the sensor is stopped. This is to restore the initial state along with the repair of (1).

In this way, the detection function of the sensor (1), which is used to detect abnormalities that occur in various working parts of agricultural machinery, etc., can be used to shorten the alarm (2) in order to alert the worker. The voice monitor (3), which was activated at the same time, can be stopped after being activated for a certain period of time, and the operator can be repeatedly explained until the operator is satisfied and activates the voice stop switch (4). When an abnormality occurs, the alarm (
By calling attention to a level that does not cause discomfort through 2) and providing convincing explanations through the voice monitor (3), the operator does not have to perform any troublesome operations, and can make accurate judgments and take appropriate measures to detect abnormalities. This can be prevented from occurring.
