Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The projector mainly comprises a light source, a light condensing system and a plane reflector. The light generated by the light source firstly passes through a light-gathering system of the projector, is gathered and then is emitted to the plane reflector, and is reflected into parallel light by the plane reflector to be mapped onto the screen, so that the projection function is realized.
The light-gathering system of projector is formed from light-gathering lens, auxiliary light-gathering lens, screw lens and carrying glass. The screw lens, also called Fresnel lens, is composed of two thin flat organic glass plates carved with concentric screw threads, and has large caliber, light weight and good light transmittance, and can play the role of a large-caliber convex lens. It can only operate below 70 degrees celsius and beyond this temperature it can cause distortion and reduce the life of the projector. The auxiliary condenser or crescent moon mirror is positioned between the light source and the condenser, and plays a role in reducing the surface temperature of the Fresnel lens. The object carrying glass is positioned on the threaded lens, so that the projection film can be projected, written and demonstrated by some experiments or teaching aids.
The flat mirror functions to convert vertical light from the light source to horizontal so that it can be projected onto a screen. The plane mirror also plays an important role in the use of the entire projector, and if the projector is used without the plane mirror being opened, the light emitted by the light source will be reflected back to the light source after passing through the spotlight, which will increase the temperature inside the projector and on the surface of the light source, and reduce the life of the projector. Therefore, when the projector is used, the plane mirror is opened, so that the direction of light can be changed, images or videos can be mapped on a screen, and the mission of the projector is completed.
There are also some important electrical and ventilation devices in projectors, such as transformers and fans. The transformer is used to convert 220V commercial power into 24V AC voltage for projection lamp. Most projection lamps are 24V/300W bromine tungsten lamps, and the temperature in the projector lamps rises during the working process, so a squirrel cage fan is needed to reduce the temperature in the projector lamps, and a large amount of heat generated during the working process of the projection lamps is timely discharged out of the body so as to avoid damaging screw lenses and electrical equipment.

Referring to fig. 2A, fig. 2A provides a parameter fault-tolerant output method for an intelligent projector, which is implemented by using the intelligent projector shown in fig. 1, and the method shown in fig. 2A includes the following steps:
s201, reading a first value of the first parameter.
In concrete implementation, when the intelligent projector acquires the first parameter, due to the fact that manufacturers producing the intelligent projector are different in product implementation schemes, the phenomenon that accidental jumping of the first parameter is inconsistent can occur, the first parameter is judged by mistake by the intelligent projector, and wrong prompt of the intelligent projector is caused.
The first parameter is a parameter indicating the working state of the intelligent projector, which is generated by the intelligent projector during the operation process, for example, parameters such as a fan speed, a fan working state, a battery power, a battery charging state, a laser light source temperature, a camera temperature, and the like, and is not limited herein, in a specific implementation, the intelligent projector may be provided with a sensor component, various parameters of the intelligent projector during the operation process may be collected based on the sensor component, and a sensor in the sensor component may be at least one of the following parameters: a capacitance sensor, a vibration detection sensor, a temperature sensor, a pressure sensor, a light sensor, an image sensor, and the like, which are not limited herein.
The first value is data information corresponding to the first parameter, and the first parameter is different in value range, for example, when the first parameter is battery power, the value range of the first value is 0 to 100%, and when the first parameter is camera temperature, the value range of the first value is-2 to 50 ℃. When the intelligent projector normally works, the sensor assembly sends the detected first parameter and the corresponding first numerical value to the processing assembly by sending the state information to the processing assembly.
The implementation method of step S201 may be implemented by acquiring status information sent by the sensor component to the processing component, for example, when the sensor component sends the status information to the processing component, sending a first value instruction for querying a first parameter to the processor, after receiving the first value instruction for querying the first parameter, the processor retrieves the first value of the first parameter from the memory and sends response information to the intelligent projector, and after receiving the response information, the intelligent projector reads the first value of the first parameter in the response information. Of course, in practical applications, the first value of the first parameter may be read in other manners.
S202, determining whether the first parameter belongs to a sensitive parameter.
Optionally, the determining whether the first parameter belongs to a sensitive parameter specifically includes: the intelligent projector determines a first name of the first parameter, queries whether the first name exists in a preset sensitive parameter list, determines that the first parameter is a sensitive parameter if the first name is included in the preset sensitive parameter list, and determines that the first parameter is a non-sensitive parameter if the first name is not included in the preset sensitive parameter list.
Wherein, the sensitive parameter list may include at least one of the following: the fan speed, the fan operating state, the battery level, the battery charging state, the laser light source temperature, the camera temperature, and other parameters, which are not limited herein.
It should be noted that the sensitive parameter list may be set by the user according to the practical scene and the user requirement, or may be set by the intelligent projector according to the important parameter in the operation process of the intelligent projector, which is not limited in this embodiment.
S203, when the first parameter belongs to a sensitive parameter, comparing the first value with a historical value to determine whether to output the first value.
Optionally, the determining, by the smart projector, whether to output the first numerical value by comparing the first numerical value with a historical numerical value may specifically include: the intelligent projector compares a first numerical value with a first threshold value to determine whether the first numerical value is abnormal or not, if the first numerical value is abnormal, the historical abnormal times of the first parameter are extracted, if the historical abnormal times do not exceed a second threshold value, the first numerical value is determined not to be output, and if the historical abnormal times exceed the second threshold value or the first numerical value is not abnormal, the first numerical value is output.
Optionally, the determining, by the smart projector, whether to output the first value by comparing the first value with a historical value further includes: if the first numerical value is not abnormal, clearing the historical abnormal times; and determining not to output the first numerical value, and adding one to the historical abnormal times.
Specifically, when a first parameter belongs to a sensitive parameter, comparing the first value with a first threshold to determine whether the first value is abnormal, when the first value is abnormal, extracting the historical abnormal times of the first parameter stored in a memory, when the historical abnormal times is greater than a second threshold, outputting the first value, when the historical abnormal times is less than or equal to the second threshold, not outputting the first value, and increasing the historical abnormal times by 1; and when the first numerical value is abnormal, clearing the historical abnormal times and outputting the first numerical value.
The historical abnormal times are times of error information of the first parameter, the intelligent projector stores the historical abnormal times in the memory, when the first value is abnormal, the intelligent projector extracts the historical abnormal times from the memory, and when the first value of the first parameter is abnormal once, the historical abnormal times are increased by 1.
The first threshold is used for determining whether the first value is abnormal, when the first value is larger than or smaller than the first threshold, the first value is determined to be abnormal, otherwise, the first value is determined to be normal, the first parameter is different, the corresponding first threshold is also different, the first threshold can be set by the intelligent projector according to an actual application scene, for example, when the first parameter is the battery power, the value range of the first value is 0-100%, the first threshold can be 20%, when the first parameter is the camera temperature, the value range of the first value is-2 ℃ to 50 ℃, and the first threshold can be 50 ℃. The second threshold is the maximum number of times of error information of the first parameter, and the second threshold can be set by a user according to a practical scene and user requirements, or can be set by the intelligent projector according to the practical scene, and the embodiment does not limit the number of times.
It can be seen that, the parameter fault-tolerant output method for the intelligent projector described in the embodiment of the present application is applied to the intelligent projector, and is configured to read a first value of a first parameter, determine whether the first parameter belongs to a sensitive parameter, and compare the first value with a historical value when the first parameter belongs to the sensitive parameter to determine whether to output the first value. According to the method, whether the first numerical value is output or not can be selected by comparing the first numerical values of the sensitive parameters, so that error prompt can be avoided, and the user experience is improved.
In a possible example, as shown in fig. 2B, after step S203, the method may further include:
s204, identifying an application scene, determining a control command corresponding to the first numerical value according to the application scene, and executing the control command.
The application scenarios may include, but are not limited to: a home scenario, a corporate scenario, or an outdoor scenario.
The method for identifying the application scene can be realized by acquiring the pictures and acquiring the plurality of environmental parameter values, and can be realized by acquiring the working mode of the intelligent projector, for example, when the application scene is a family scene, a user can set the working mode of the intelligent projector to be the family mode, and the intelligent projector can identify the application scene through the working mode. As long as it can be ensured that the intelligent projector can recognize the application scene, this embodiment does not impose any limitation on this.
Determining the control command corresponding to the first numerical value according to the application scenario may specifically include: and generating a corresponding control instruction according to the value range gradient of the first value according to different application scenes, for example, when the first parameter is the battery capacity, if the first value falls between (0, 10% >), generating a first control instruction, and if the first value falls between (10%, 20% >), generating a second control instruction, wherein the first display control instruction is used for displaying information to remind a user that the battery capacity is less than or equal to 10%, and starting a power saving mode, and the second display control instruction is used for displaying to remind the user that the battery capacity is less than or equal to 20%.
Further, the intelligent projector executes corresponding operations according to the generated control instruction, for example, when the generated control instruction is the first display control instruction, the intelligent projector displays information of "current electric quantity is less than 10%, please charge in time" through the projection device, and starts a power saving mode of the intelligent projector, that is, the projection brightness is adjusted to be half of the current projection brightness.
It should be noted that, because manufacturers that produce the intelligent projectors are different in product implementation schemes, response results generated by executing the generated control command by the intelligent projectors of different models are different, and a specific response result is set by a manufacturer of the intelligent projector, which is not limited herein.

the intelligent projector compares a first numerical value with a first threshold value to determine whether the first numerical value is abnormal or not, if the first numerical value is abnormal, the historical abnormal times of the first parameter are extracted, if the historical abnormal times do not exceed a second threshold value, the first numerical value is determined not to be output, and if the historical abnormal times exceed the second threshold value or the first numerical value is not abnormal, the first numerical value is output.
