## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a technology for booting a handheld apparatus, and more particularly to a device and a method for booting a handheld apparatus by voice control.
2. Description of the Related Art
At present, most machines used in a production line involved an operation of powering on various different components of the machines, and the power-on operation is usually taken place manually, since the manual control requires less technical skill. Although the manual power-on operation can save costs for a short term, yet there are drawbacks in mass production for a long term. The power-on operation of some handheld apparatuses requires a long-time pressing procedure before the apparatuses enter into a working program. If the power-on operation is performed manually, a user's fingers may get fatigue easily, and the working efficiency may become lower substantially. Therefore, it is an important subject for manufactures to develop an automated machine to enter into a desired working program.
SUMMARY OF THE INVENTION
It is a primary objective of the invention to overcome the aforementioned shortcoming of the conventional handheld apparatus that requires a longer time of pressing in order to power on the handheld apparatus by providing a device for booting a handheld apparatus by voice control in accordance with the present invention.
To achieve the foregoing objectives, the present invention provides a device for booting a handheld apparatus by voice control, which comprises: a base having an opening formed on a surface of the base; a trigger switch protruded from the surface of the base; an acoustic sensor disposed within the opening; and a power-on device including a pushing device and a pressure head. When the handheld apparatus is placed at the base and the trigger switch is triggered, the trigger switch controls the power-on device to power on the handheld apparatus. When the handheld apparatus is turned on, the acoustic sensor detects a sound from the handheld apparatus, and the pressure head of the power-on device is controlled and moved away.
In a preferred embodiment of the present invention, a power-on device for booting a handheld device by voice control comprises a time relay, and a time relay signal coupled between a solenoid valve and an acoustic sensor. If the trigger switch triggers the solenoid valve, and the acoustic sensor detects a sound produced by the solenoid valve, then the acoustic sensor will send a signal to the solenoid valve to control and move away the pressure head, so that the power-on device will be unable to complete the operation of booting the handheld apparatus, and the time relay will block a mis-trigger of the acoustic sensor caused by a sound of the solenoid valve. In general, the powered-on device will start a time relay, and the action time of the time relay is approximately equal to the action time of the solenoid valve. In a preferred embodiment of the present invention, the time relay blocks the signal generated by the acoustic sensor for 2 seconds. The sound intensity of the acoustic sensor of the present invention falls within a range from 70 decibels to 90 decibels.
The power-on device controlled by the solenoid valve comprises a pushing device and a pressure head, and persons ordinarily skilled in the art should understand that the power-on device includes a pushing device which can be a pneumatic cylinder, a hydraulic cylinder, or an electric motor. The solenoid valve controls the air pressure in a cylinder, and the air pressure drives and moves the pressure head of the power-on device. In general, the air pressure of pressing or rebouncing the pressure head of the power-on device is approximately equal to 0.1±0.02 MPa.
The present invention further provides a method for booting a handheld apparatus by voice control, and the method comprises the steps of: placing the handheld apparatus at a base and triggering a trigger switch disposed on the base; controlling a power-on device by the trigger switch to power on the handheld apparatus; and detecting a sound from the handheld apparatus by an acoustic sensor to control and move away the power-on device, after the handheld apparatus is turned on to produce the sound. After the trigger switch turns on the solenoid valve, the solenoid valve controls the power-on device to power on the handheld apparatus. The acoustic sensor detects a sound and the solenoid valve controls and moves away the pressure head of the power-on device.
In another preferred embodiment of the present invention, when the trigger switch turns on the solenoid valve to control the power-on device to power on the handheld apparatus, the solenoid valve starts a time relay to block a signal generated by the acoustic sensor after a mis-trigger of the acoustic sensor is caused by a sound of the solenoid valve, wherein the action time of the time relay is approximately equal to the action time of the solenoid valve, and the time relay for blocking the signal generated by the acoustic sensor is equal to 2 seconds in this preferred embodiment.
After the handheld apparatus is powered on, it is necessary to confirm that no defective production line as shown follows and appears in the boot screen. After the pressure head of the power-on device is acted to press on the closed button of the handheld apparatus for 7 to 8 seconds, the boot screen appears, and the booting procedure ends. If the pressure head is pressed continuously, the handheld apparatus will enter into another program, so that when the boot screen of the handheld apparatus appears and the speaker produces a sound, the boot sound triggers the acoustic sensor, and after the acoustic sensor detects the sound of the handheld apparatus, the solenoid valve controls and moves away the pressure head of the power-on device.
In addition, the device for booting a handheld apparatus by voice control can be used for inspecting a handheld apparatus that produces no sound. After the handheld apparatus is booted and the pressure head of the power-on device is not rebounded, it is determined that the speaker fails to produce sound, so that there must be a problem existed in the interface of the handheld apparatus and causing the speaker not to produce sound.
With the device for booting a handheld apparatus by voice control in accordance with the present invention, the pressure head of this device can be used for booting the handheld apparatus automatically. When a booting sound is produced, the acoustic sensor can detect the sound of the handheld apparatus, and the solenoid valve controls and moves away the pressure head of the power-on device. For an operation in a production line, it no longer requires pressing the button manually for a long time, so as to facilitate the operation and enhance the efficiency of the handheld apparatus.
