Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In the conventional technology, as described in the background art, most of projectors adopting emerging operating systems such as the android system are closed after the optical engine is closed, and it takes a long time to start the system again, which is much longer than the start time of the optical engine. Resulting in a particularly long turn-on time for the user each time the user uses the projection device.
In view of the above, in one embodiment, as shown in fig. 1, a method for controlling an operating state of a projection apparatus is provided, the method including:
s20: detecting whether a starting trigger signal exists or not in a standby state of the projection equipment, wherein the standby state of the projection equipment refers to the power-on work of an electronic circuit of the projection equipment;
s40: and if the starting trigger signal is detected in the state that the optical-mechanical assembly of the projection equipment is closed, controlling the optical-mechanical assembly of the projection equipment to work so as to project the picture to the projection surface.
The optical-mechanical assembly receives the information of the picture to be projected sent by the signal source through the electronic circuit, and the processed information is projected through the projection lens. The electronic circuit is a processing component of the existing projection device, and is not described in detail herein. According to the method for controlling the working state of the projection equipment, when the projection equipment is controlled to be powered on, an electronic circuit part keeps working, and the electronic circuit is a hardware part circuit supported by a background system. When the optical-mechanical assembly is turned off in the standby state, how to quickly implement the image projection is a very important factor for improving the customer experience when the user needs to perform the projection. The user can trigger and generate the starting trigger signal in various modes, in the projection equipment working state control method, whether the starting trigger signal exists or not is continuously detected, so that when the user needs to use the projection equipment for projection, namely the starting trigger signal is detected, an optical mechanical component of the projection equipment is immediately controlled to work, and as the background system is always in a working state, the projection of a video signal source can be immediately carried out, the starting speed is high, and the user experience is good.
In one embodiment, as shown in fig. 1, in the standby state of the projection apparatus, before the step of detecting whether there is a power-on trigger signal, the method further includes the steps of:
s10: when the projection equipment is powered on, an electronic circuit of the projection equipment is controlled to work, and an optical mechanical component of the projection equipment is controlled to be closed.
When the projection equipment is powered on, the electronic circuit part of the projection equipment is controlled to work by default, and the optical machine component is maintained to be in the closed state, so that the startup trigger signal is detected in the low power consumption state, namely when a user does not need to use the projection equipment, the projection equipment can maintain the low power consumption working state, and the energy-saving and environment-friendly effects are achieved.
In one embodiment, as shown in fig. 2, the step S20 of detecting whether there is a power-on trigger signal in the standby state of the projection apparatus includes:
s21: parallelly detecting a signal source accessed by the projection equipment in a standby state;
if the start trigger signal is detected in the state where the optical-mechanical assembly of the projection device is turned off, the step S40 of controlling the optical-mechanical assembly of the projection device to work includes:
s41: and if the projection equipment is detected to have signal source access in the state that the optical-mechanical assembly of the projection equipment is closed, selecting a target signal source, and controlling the optical-mechanical assembly of the projection equipment to work, wherein the target signal source is one of the signal sources accessed by the projection equipment.
The control method provided by the embodiment of the application can detect whether the signal source is accessed at the first time by parallelly detecting the signal source accessed by each interface or wireless signal channel of the projection equipment, compared with the traditional technologies, the method detects whether the formulated signal source is accessed at first and then carries out other signal source detection modes according to the sequence. Compared with a mode that a user needs to press a starting key to start the computer, the method can take the access of the signal source as a trigger condition, and can effectively reduce user operation. Especially, in application scenes such as a living room and a bedroom, once a user is connected with the projection equipment through a mobile phone, namely the mobile phone provides a signal source to the projection equipment through a wireless local area network, at the moment, the optical-mechanical assembly is immediately controlled to work, the user can see pictures played on a mobile phone terminal on a projection surface, the whole process does not need the user to perform extra starting action, the user operation is few, and the experience is good.
In one embodiment, as shown in fig. 3, the selecting step of the target signal source includes:
s411: and if the multipath signal source is detected in the state that the optical-mechanical assembly of the projection equipment is closed, selecting the newly accessed signal source as the target signal source.
When a user receives multiple signal sources, based on an application scenario, data sent by a last signal source is often data to be displayed finally, so in the control method, when the multiple signal sources are accessed, a latest signal source is selected, that is, the latest signal source is switched to, and an optical-mechanical assembly in the projection equipment is driven to project a picture corresponding to the data transmitted by the latest signal source.
In one embodiment, the signal source comprises: signals accessed through an HDMI interface; and/or, a signal accessed through a DP interface; and/or, signals accessed through a USB interface; and/or signals accessed through a wireless network.
The HDMI (High Definition Multimedia Interface) is a fully digital video and audio transmission Interface, and can transmit uncompressed audio and video signals, and a user can connect a computer and a projection device through an HDMI Interface line, so that the HDMI signal source can be accessed. The dp (displayport) interface is the first display communication port that relies on packetized data transmission technology to replace the traditional VGA, DVI and FPD-link (lvds) interfaces. The interface is backward compatible with legacy interfaces (e.g., HDMI and DVI) through active or passive adapters. A USB (Universal Serial Bus) interface is an interface for standardizing the connection and communication between a computer and external equipment, and a USB disk can be connected to a projection device through the USB interface or a mobile phone can be connected to the projection device through a USB cable to realize data access. In addition, the signal source can also be a signal accessed through a wireless network, for example, a mobile phone is connected through a WIFI wireless local area network to perform screen projection or on-screen display.
The detection process of the HDMI interface and the DP interface signal source may be that the high-low of the HDMI/DP interface access general input/output voltage signal is detected through hardware, if the high level is high, whether a video source exists is further detected through a software program, if the video source exists, it is determined that the HDMI/DP interface has the signal source access, otherwise, it is determined that no signal source accesses in other situations.
The detection process of whether the USB interface is connected to the signal source may be: the USB interface access voltage is detected through hardware, if the access voltage is high level, whether the USB interface is connected with a mobile phone or a USB flash disk is further detected through software, specifically, whether the USB interface is connected with the mobile phone or the USB flash disk is judged by trying to start a video protocol, and whether the USB flash disk is connected is judged by detecting a storage space. If the video protocol is detected, it is judged that a mobile phone wired screen projection signal is accessed to the projection equipment, and if the storage space is detected, it is judged that a USB flash disk is accessed through the USB interface, and files in the USB flash disk can be browsed.
The detection process for WIFI wireless signal access may be: the WIFI screen projection protocol is detected, whether a mobile phone is connected or not can be judged according to the detected protocol, if the WIFI screen projection protocol is connected, the mobile phone of which type is connected can be judged according to specific protocol content, for example, if the WIFI screen projection protocol is an airplay protocol, the access of a non-android wireless screen projection signal can be judged, and if the WIFI screen projection protocol is a miracast protocol, dlna protocol or dial protocol, the access of the android wireless screen projection signal can be judged. Therefore, the method provided by the embodiment of the application can not only detect whether a signal source is accessed, but also realize the type judgment of the accessed signal source and support the data transmission of various protocols.

s60: and if the signal source connected to the projection equipment is detected to be completely disconnected, controlling the optical-mechanical assembly of the projection equipment to be closed.

And the optical machine component is kept closed instead of the whole projection equipment is shut down, so that the optical machine can be immediately started to project and display the image of the signal source when the signal source is accessed next time.
