Abstract
The utility model discloses a power window automatic control device. A pressure sensor, a light-emitting diode (LED), a buzzer and a singlechip are added to an existing power window. The power window automatic control device of a present modern car is composed of a window lifter, an electric motor, a switch, the pressure sensor, the LED, the buzzer and the singlechip, wherein the added pressure sensor, the LED, the buzzer and the singlechip are connected with the singlechip. The pressure sensor is used for detecting pressure difference in the interior and exterior of cars and transmitting detected signals to the singlechip, the singlechip judges the located environment conditions of the cars through signal processing and outputs different signals so as to control car windows of the cars.
Description
Technical field
The utility model belongs to automotive electric equipment automatic control technology field, is specifically related to a kind of pressure inductive power windows automaton.
Background technology
Existing electric car-window control device mainly is comprised of parts such as window regulator, motor and switches.In order to improve safety, present electric car-window control device is after vehicle motor is flame-out, time-delay relay time-delay in control circuit relay contact disconnection after tens of seconds, cut off the power supply of power windows, this has improved the safety of vehicle to a great extent, but also find gradually in daily life the deficiency of this type of control device, in the time of for example in vehicle is drowned entry, the car owner can't open car door so that loss of life, this is relevant with the electric car-window control device of present use to a great extent, after automobile was drowned, because the car inside and outside differential pressure is very big, the car owner can't open car door internally, and power windows namely is cut off power supply behind engine misses, can not normally open, this has just caused threat to car owner's life security, is the large defective of one on the power windows control technology.
Summary of the invention
The purpose of this utility model is to provide a kind of pressure-sensitive electric car-window control device that can automatically open according to the poor control vehicle window of car external and internal pressure.
For this reason, the power windows automaton that the utility model provides comprises window regulator, motor and the switch that connects successively, it is characterized in that, this control device further comprises single-chip microcomputer and is installed on respectively Che Nei and two pressure sensors that car is outer, described switch with are connected a pressure sensor and are connected with single-chip microcomputer respectively.
This control device further comprises an alarm, and this alarm is connected with single-chip microcomputer.
This control device further comprises a LED lamp, and this LED lamp is connected with single-chip microcomputer.
Described single-chip microcomputer adopts the MSP430 single-chip microcomputer.
Device gathers the inside and outside pressure differential of automobile by pressure sensor, and this signal passed to the control core single-chip microcomputer, process through single-chip data, the control power windows is in different mode of operations under the varying environment state, to ensure the safety of driver and vehicle.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to figure 1, pressure-sensitive power windows automaton of the present utility model comprises window regulator, motor, switch, two pressure sensors, LED lamp, buzzer and single-chip microcomputers, wherein, motor drives the window regulator motion by changing positive and negative transferring, thereby drives moving up and down of glass for vehicle window; Two pressure sensors are installed on respectively outside Che Nei and the car, are used for the inside and outside pressure differential of measured automobiles; LED etc. and buzzer are in order to produce alarm signal; Single-chip microcomputer is as the control centre of whole device, at first receive the signal that two pressure sensors gather, and calculating difference between the two, surpass secure threshold such as this difference, single-chip microcomputer is opened gauge tap, then controls motor operation, and motor drives the window regulator motion by changing positive and negative transferring, thereby drive moving up and down of glass for vehicle window, Single-chip Controlling LED lamp and buzzer send alarm signal simultaneously.Single-chip microcomputer in this device adopts the MSP430 single-chip microcomputer.
Single-chip microcomputer is as the control centre of whole device, at first receive the signal that two pressure sensors gather, and calculating difference between the two, judge the residing ambient condition of vehicle, when the automobile external and internal pressure is poor when being in the normally-pressured neighbor, the duty of device is consistent with the power windows that exists at present, be that control circuit is after receiving switching signal, glass for vehicle window is realized normal elevating control, and behind the engine misses, time-delay relay in the control circuit cuts off the control power supply of power windows through after the of short duration time-delay.When the poor normal range (NR) that exceeds of automobile external and internal pressure, when the car external pressure is far longer than interior pressure, single-chip microcomputer will be controlled LED etc. and report to the police with buzzer, shield simultaneously the time-delay relay in the control circuit, guarantee the power supply supply of power windows behind engine misses, can work, namely can normally open.
The electronic devices and components that adopt in the device of the present utility model are commercially available known product, and those skilled in the art can realize the connection of each electronic devices and components according to the application's technique effect.
