Automobile GPS positioner and automobile humidity detection method

Abstract

The invention discloses an automobile GPS positioner and an automobile humidity detection method. According to the method, a humidity sensor sets a warning value as P, a regular time detection modulesets regular time as t, the regular time detection module sends out a signal to a microprocessor at the interval of time t, the microprocessor drives a heating module to preheat the interior of a shell, preheating time is set as T, and frost or water drops in the shell are heated to evaporate; after the preheating time reaches the time T, the humidity sensor detects the humidity in the shell, andthe humidity value detected by the humidity sensor is P1; and when P1 is greater than P, the humidity sensor sends a signal to the microprocessor, the microprocessor drives the heating module to perform second heating on the interior of the shell, and meanwhile the microprocessor drives a motor to rotate so as to open a dehumidification plate. The humidity sensor can detect the humidity in the shell; and when the humidity is excessively high, a temperature control module can heat the interior of the shell, so that moisture in the shell is discharged.

Description

technical field [0001] The invention belongs to the field of locators, and more specifically relates to an automobile GPS locator and a method for detecting humidity thereof. Background technique [0002] Some current cars will be equipped with a locator to locate the position of the car; the current locator includes a microprocessor, a power module, a GPS positioning module, a photoelectric sensor module, a communication module and a magnet adsorption module. There is a magnet on the shell, in order to ensure that the locator has a good enough positioning effect, the locator is generally adsorbed to the bottom of the car chassis through a magnet, so as to avoid the influence of the metal shield in the car on the positioning effect of the locator; but the positioning The positioner placed under the chassis and in direct contact with the outside world is prone to moisture, resulting in excessive humidity inside the housing, which affects the operation of the circuit board ins...
