METHOD FOR PREVENTING SENSOR TROUBLE [0002]

The present invention relates to a method for detecting a sensor malfunction of a feeder, and more particularly, to a method of detecting a malfunction of a feeder sensor by detecting a liquid feed or a liquid level stored in a feed holder, And a method of detecting a malfunction of a sensor of a feeder so that the malfunction can be stopped.

Generally, feeds and drinking water are fed to livestock such as pigs, cattle, goats, sheep and the like (hereinafter collectively referred to as "livestock") in a farm or a farmhouse where feeds and water are fed at the same time A wet feeder for feeding, or a dry feeder for separately feeding feed and water.

On the other hand, feeds have various kinds of particles, particle size, volume, viscosity, etc., and aggregation and lumps are generated due to moisture, so that special care is required, and the feeds contained in the hopper are not periodically stirred, It will be provided in good condition. In this case, if the supply ratio of feed and water is not appropriate, the feed becomes dull and easily deformed and the risk of disease is serious. Therefore, the corrupt animal feed must be poured from the feed support before the livestock is eaten, As this large, high feed and water supply is required, there is a desperate need for a device that can automatically control the feeding of feed and water.

As a prior art for solving such a problem, registration number 10-1410117 (hereinafter referred to as prior art), which was filed with the Korean Intellectual Property Office on May 15, 2012, ).

The prior art includes a hopper having a feed port and a feed port at a lower portion thereof, a feed pedestal provided at a lower portion of the hopper, a feed discharging means inside the hopper, and a controller, And a drinking water supply means for supplying drinking water to the lower feed support through the central shaft is provided.

When the water and the feed are mixed with each other, the driving motor and the solenoid valve are stopped or shut off, the livestock is fed with the liquid food, the high-level sensor is exposed, and the food is continuously consumed Finally, it is clear that the low-water sensor is a useful tool for re-feeding feed and water.

However, it is not easy to ascertain whether the high-level sensor and the low-level sensor are operating correctly in the prior art, and therefore the operator must judge that the sensor is operating through the feed and water contained in the feedstock. This is because if the sensor fails, the control unit does not receive the signal and continues to supply the water and feed more than the predetermined amount, or the control unit continuously feeds the feed and water, . Therefore, the operator must periodically check the amount of feed and water contained in the feed support, which results in a great waste of manpower and inconvenience in management.

At this time, when the liquid feed discharged to the feed tray 20 comes into contact with the row sensor 50 and the row sensor 50 senses this, the controller 70 outputs a signal. At this time, the high sensor 60 The control unit 70 drives the feed motor 32 again and opens the solenoid valve 42 to automatically feed the feed and water to the feed support 20. [

At the same time, the control unit 70 turns on the low sensor operation display unit 92 of the display unit 80 so that the operator can visually confirm that the row sensor 50 is operating normally (S20).

Then, when a certain amount of feed and water is supplied to the diathesis pedal 20 and the high sensor 60 senses it (S30), the control unit 70 outputs a signal to the control unit 70. The control unit 70 controls the feed motor 32 The drive is stopped, and the solenoid valve 42 is closed to cut off the supply of feed and water.

At the same time, the control unit turns on the high sensor operation display unit 90 of the display unit 80 to allow the operator to visually confirm that the high sensor 60 is operating normally (S40).

On the other hand, when the failure of the row sensor 50 or the high sensor 60 occurs, the row sensor and the high sensor operation display sections 90 and 92 become the "OFF" state in which the state of the number "0 & The controller 70 determines that the high sensor 60 and the low sensor 50 have not been operated for a predetermined period of time (S50) The drive of the motor 32 is stopped and the solenoid valve 42 of the water supply unit 40 is closed to forcibly cut off the supply of the feed and water in step S60. Then, the display unit 80 is blinked, So as to promptly notify workers of unnecessary feed waste (S70).

Next, when the livestock feeds the feed and water contained in the diathesis pedal 20 and the high sensor 60 is exposed to the outside (S80), the high sensor operation display 90 displays the number 0 in the "off" state S90).

Next, when both the feed and water contained in the dietary supporter 20 are consumed by the livestock and the row sensor 50 is exposed to the outside (S100), the row sensor operation display unit 92 displays the number "0" (S110).

If the row sensor 50 maintains the ON state during the erroneous operation setting time, it is determined whether the row sensor 50 continuously maintains the ON state during the erroneous operation setting time (S120) It is determined that an erroneous operation has occurred due to the foreign matter, so that the feed motor 32 and the solenoid valve 42 are operated to feed the feed and the water, thereby preventing accidents that the livestock can not eat for a long time (S130).

At the same time, the display unit 80 generates another type of alarm sound together with another type of flicker signal so that the operator can check the alarm sound immediately (S140).
