Abstract

PURPOSE:To enable warning voice to be positively heard by supplying power source to a warning voice circuit for a predetermined time to generate the output of the warning voice in the predetermined time even if some abnormalities are detected to turn off a power switch. CONSTITUTION:In abnormalities that a rough rice bag is filled with rough rice in operation of a combined harvester and thresher, tractor, etc. for example, the signal of a rough rice sensor 1a is sent to a microcomputer 2 which operates a buzzer unit 8. Thus, an operator turns off a key switch 4 to stop an engine while delaying by a predetermined time the turning-off of a transistor 11, microcomputer 2, etc. with an off-delay circuit 10. During that time, the sentence word signal corresponding to abnormalities detected by the microcomputer 2 is read out of its built-in memory to generate and add the output to a voice composing unit 5 for reading out sound system corresponding to the sentence word signal from ROM6 for composite sound so that the output of voice like ''Bad is full of rough rice'' is generated from a speaker 7.

Description

[Detailed Description of the Invention] This invention is based on #J! #Relating to machine alarm systems. - For agricultural machinery such as harvesters, combine harvesters, rice transplanters, rice transplanters, etc., it is possible to give voice instructions for the starting point and six cypress planting items, and also to detect problems with the engine during one operation, such as running out of fuel or hydraulic system. , Drops in can #4 pressure, abnormally high engine coolant water, low F in the liquid ◆, abnormalities in the 411I roof of the combine, for example, the paddy bag is full of paddy, or the rice is being handled improperly. In order to instruct the operator in the event of a low rotation, a 1 second delay in the second thrower, a blockage in the straw removal cutter, etc., there is a device that issues an audible alarm to notify the operator of the abnormality. 8 for convenience stores, etc. that have such alarm devices.
There is a stop kumpu and a stop gude in one desert.

A case i is when a machine abnormality is known from an alarm sound output.

For a+im safety, the operator must turn off the Mll power switch and stop the engine. However, by updating the magnetic wire switch, the audio book 11
If the 4IIA of the prefecture is also disconnected, the berthing output will not be output, and the s
*I can fully understand wifr. However, after the 4-source switch JFi, it may have been turned further to L)N. The assistant will return to the beginning, and the audio for the initial 4-point injection will be played, causing an O-sense for an hour.

On the other hand, abnormalities may occur not only in one location but also in other locations. In such a case, if you immediately reset the 4#I switch even after hearing the alarm sound indicating an abnormality in the station, you will end up ignoring the warning sound that you cannot see or hear in the future. Become. Furthermore, there are cases where even if the combine harvester outputs the first alarm sound while producing sputum, it cannot be heard because the fish is large.

The purpose of this @ Ming is to make sure that even if the 4-source switch is disconnected due to electricity generation, the abnormality alarm sound that occurs can be heard a/'L, and that it can be heard accurately without being bothered by the noise. The aim is to provide an alarm system for AM Ling.

In order to achieve the above object, the device d1 of the present invention is designed such that even if the heel switch is renewed by adding **,
1I supplies 4# to the alarm sound @path so that the alarm sound is output within this predetermined time.

The present invention will now be described in detail based on the implementation of the four pots shown in direction A when applied to a combine harvester.

ε^ on the first side, (11) is the paddy sensor, (lb) is the fuel senna, and the paddy centimeter (la) ri When the paddy bag is full of paddy, the 11a feed senna (lb) detects the fuel in the engine. When it breaks, it is a sente that spews out its abnormal state. Although not shown, these moderate senna (Iris)
In addition to the fuel sensor (lb), a sensor f (lC) (1 m) for detecting an abnormality is arranged in parallel. These various sensors (1m), (lb), ... (one detection signal is individually controlled) are configured so that they can be stored in the microcomputer (2) for the o-ring. . Sen on the other hand? (1ri, (lb), -(Iff) to Fi411
A#/1bt is connected so that 4-source can pressure is supplied via the 4 pond (3)) and the power key switch 4).

The microcomputer (2) is coupled to a voice synthesizer 5), and furthermore, the voice synthesizer! It device 111 +5) is coupled to synthesized sound 310M-). In addition, a speaker (71) for outputting the voice of the voice synthesizer is connected.The microcomputer (2) has a built-in memory, and this memory contains the sentence 8 signal for outputting the alarm voice corresponding to AJt. is memorized.Furthermore, the microcomputer (2
) is connected to a goude system (8) for first emitting a warning sound when any foreign material is detected. 4
Ryosukeike (3)'s plus IIIJ is relay cheer, 9)
When connected to the microcomputer I2) through
It is connected to the off-play circuit via a 4#I key switch (4). The OR play circuit is a circuit that, when the heel key switch +4) is OR, outputs the OR J1 work by extending W4# for a certain period of time.

The output terminal of the or-play circuit is the current -j#l resistance (rt
) to the base of the NPN transistor I. The emitter 4ItL of the transistor I is connected to ground, and connected to the 4IIA +3) through the parallel connection of the collector 4-pole resistor coil and the bypass diode 1.
4) When turned on, it is turned on by the signal output from the off-dare 44g circuit, and when turned on, the relay coil is turned on.
4 currents are applied to the relay contact, and the IIIE source is
4 a +3> to the microcomputer 12).

Considering the case where the % key switch +4) is now turned on, relay contact 1g +93 is closed (S), microcomputer (2) K- is supplied with IEIIIA can pressure (1), and microcomputer (2) K- is supplied with IEIIIA can pressure. (2) is the normal t
lJ#--Execute the operation. If some abnormality occurs here, for example, if the paddy bag becomes full and the paddy sensor fCLm) produces -, then the ejection signal of this paddy sensor t(l) is stored in the microcomputer +2), and first A gude is sounded as an abnormality warning sound by the gude device.

The operator hears this warning sound and immediately turns off the '4# key switch-4). As a result, each cypress senna (11
), (lb), -(1m) are cut off, and the engine not shown also stops. However, the power key switch I4)
The off-state of transistor I is output with a certain time delay in the off-play time w11JU, so the off-state of transistor I is delayed by a certain time,
Therefore, the relay contact (9) is also turned off at a certain time tRM. During this fixed time period, the power of the 411 microphone a computer (2) will not be ORed, so an alarm sound will be output within this time period. That is, microcomputer t2
The text signal N6 corresponding to the abnormal state detected in step 1 is read out from the built-in memory, outputted, and added to the speech synthesis value dts).

Speech synthesis device-5).

The quantitative system corresponding to the added nine sentences Sa9 is used as a synthesized sound L U
M, from 61, synthesize voice, speaker (7)
Output from For example, in the case of an abnormal ejaculation caused by Nesenna (lal), an alarm sound saying 'a is full' will be output.

8. Even if the occurrence of A always occurs in two or more places, the glance sound can be output in sequence.
! ! Sufficient extra time is expected for the delay time of the first route.

In Sadase Bay, the alarm system for combine harvesters has been described above, but there are 14 situations regarding tractors, rice transplanters, etc., and this invention is intended to improve the alarm system for these machines.
Applies equally to equipment.

As described above, according to the alarm device for quality wood 4111 & carpet of the present invention, when foreign material occurs, the 4m switch is cut off (even if it is opened at a predetermined time, ** is supplied to the alarm audio circuit, 4II.
Even if you turn off the A switch and stop the engine, etc., the warning sound will not be as good as #111, and even if the installation warning sound occurs, the subsequent warning sound will be output without being cut. . The alarm sound is output after turning off the 4m switch and stopping the engine, etc., so the alarm can be heard with less noise, and there is no chance of missing the alarm.
