Problems solved by technology

[0004] First, when the controlled object leaves the current location, it is impossible to intelligently control the start and stop timing of the spraying, which either wastes a lot of water resources and brings troubles of frequent replenishment of water; or does not cool down in time, causing the controlled object to overheat and cause serious consequences
[0005] Second, the reliability of temperature detection is not high. When the temperature detection sensor fails, the fault cannot be effectively isolated, water resources are wasted at the slightest, and cooling fails at the worst. The reliability of automatic spray control is poor and cannot meet the needs of use.

Abstract

The invention belongs to the technical field of spraying control, and relates to a multi-logic control automatic spraying device which comprises a redundant temperature detection unit, a redundant position detection unit, a main control unit and an execution mechanism. The redundant temperature detection unit is composed of multiple paths of infrared temperature sensors and is arranged in the movement direction of controlled equipment, and direct contact with the controlled equipment is avoided through a limiting device. The redundant position detection unit is composed of multiple paths of photoelectric sensors and arranged in the direction of a straight line perpendicular to the movement direction of controlled equipment. The executing mechanism comprises a spraying head, and the spraying direction is perpendicular to the moving direction of the controlled equipment and the direction perpendicular to the straight line; and the main control unit receives signals from the redundant temperature detection unit and the redundant position detection unit, operates multiple logics and controls the execution mechanism. The control device has the advantages of being strong in function, good in real-time performance, strong in expandability, high in reliability and the like, and is particularly suitable for the automatic spraying control function of non-predetermined moving objects.

Description

technical field [0001] The invention belongs to the technical field of spray control, and specifically discloses a multiple logic control automatic spray device. Background technique [0002] For static or in situ rotating controlled objects, the existing automatic spray control devices are very mature. Generally, the spray start and stop can be controlled according to the temperature signal, and the motion state of the controlled object is not deliberately detected. [0003] However, for the controlled object that performs unpredictable movement, the existing automatic sprinkler control device has the following problems: [0004] First, when the controlled object leaves the current position, it is impossible to intelligently control the timing of starting and stopping the spraying, which either wastes a lot of water resources and brings the trouble of frequent water replenishment; or the cooling is not timely, which causes the controlled object to overheat and cause serious...
