Fire alarm device and fire alarm method for harvester

Abstract

The invention relates to a fire alarm device and a fire alarm method for a harvester. The fire alarm device comprises temperature sensors and an alarm host device, wherein the alarm host device comprises a microprocessor and a pre-alarm device; the temperature sensors are connected with the microprocessor in the alarm host device through leads; and the microprocessor is connected with the pre-alarm device. The fire alarm device has the characteristics that a plurality of sets of temperature sensors are respectively arranged in an engine room of an engine of the harvester; each temperature sensor comprises a plurality of temperature probes; each temperature probe is connected with the microprocessor; and two sets of infrared detectors are also arranged on a grain elevator in the engine room of the engine of the harvester. The fire alarm device is used for monitoring the temperature and the sundry piling height in the engine room of the engine of the harvester through the temperature sensors, the infrared detectors and the microprocessor and informing a harvester operator of the early warning and alarm information through an LED (Light Emitting Diode) and a buzzer so as to immediately adopt the treatment measures and effectively prevent the occurrence or the expansion of fire.

Description

technical field [0001] The invention belongs to a fire alarm device and an alarm method, in particular to a fire alarm device and a fire alarm method for an agricultural harvester. Background technique [0002] When the weather is hot or the climate is dry, the agricultural harvester is performing harvesting operations due to the high temperature caused by the overload operation of the engine, the abnormal friction of the machine parts, the local high temperature and the accumulation of combustible materials such as wheat straw in the cabin are the main hidden dangers of fire. The initial operator of the phenomenon can not be found in time, which makes the fire caused by the harvester often cause significant personnel and property losses. And present agricultural harvester is not equipped with the equipment that is used for fire pre-warning, alarm, can not effectively prevent the fire problem in the use process of harvester. Contents of the invention [0003] The purpose ...

Problems solved by technology

[0002] When the weather is hot or the climate is dry, the agricultural harvester is performing harvesting operations due to the high temperature caused by the overload operation of the engine, the abnormal friction of the machine parts, the local high temperature and the accumulation of combustible materials such as wheat straw in the cabin are the main hidden dangers of fire. The initial operator of the phenomenon can not be found in time, so the fire caused by the harvester often results in significant personnel and property losses

However, the current agricultural harvesters are not equipped with fire prevention and alarm equipment, which cannot effectively prevent fire problems during the use of the harvesters.
