The temperature data of sensor exports to described display, by display displays temperature data.
According to another aspect of the present invention, the invention provides a kind of automobile audio high temperature alarm method, comprising:
Real-time monitoring host computer of vedio device on vehicle external work environment temperature data, according to described external work environment temperature data
Determine whether that temperature reaches outside preset temperature;
When having in external work environment temperature data, temperature reaches outside preset temperature and the persistent period reaches Preset Time
When, send temperature anomaly prompting.
Described outside preset temperature can be 75 DEG C, and Preset Time can be 5min.
Further, after sending temperature anomaly prompting, main system of audio automatic shutdown within 5min.
The automobile audio high temperature alarm method of the present invention can also include:
The internal components temperature data of real-time monitoring host computer of vedio device on vehicle internal components, according to described internal components temperature number
It is judged that whether there being temperature to reach internal preset temperature;
When there being temperature to reach internal preset temperature in internal components temperature data, send temperature anomaly prompting.
Described internal preset temperature can be 100 DEG C.
The present invention passes through real-time monitoring main system of audio current external operating ambient temperature, carries out warning in high temperature abnormality and carries
Show.Fault alarm and shutdown protection can also be provided in main system of audio internal components temperature anomaly, contribute to user timely
Find machine fault itself.The present invention is conducive to guiding the proper use of automobile audio of user, extends the service life of automobile audio.
Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with accompanying drawing to concrete reality
Apply example to be described in detail.
As shown in figure 1, the automobile audio high temperature warning system of the present invention preferably includes main system of audio internal temperature sensor,
Main system of audio external temperature sensor, main system of audio and alarm device.Wherein, main system of audio internal temperature sensor collection sound
Ring the internal components temperature data of main frame internal components, and internal components temperature data is sent to main system of audio.Main system of audio
Internal components can include but is not limited to sound equipment power amplifier ic, power management module ic and central processing unit mcu.Outside main system of audio
Portion temperature sensor collection main system of audio external operating environment (i.e. the environment of main system of audio periphery) temperature data, and by outside work
It is sent to main system of audio as ambient temperature data.Main system of audio receives and is derived from main system of audio external temperature sensor and/or sound equipment
The temperature data of main frame internal temperature sensor;When have in external work environment temperature data temperature reach outside preset temperature and
Persistent period reach during Preset Time or internal components temperature data in when having temperature to reach internal preset temperature, export alarm signal
Number to alarm device, thus carrying out alarm.Alarm device includes speaker, can be pointed out by voice and report to the police.
The automobile audio high temperature warning system of the present invention also can also include display, and main system of audio is by being derived from of receiving
The temperature data of main system of audio external temperature sensor and/or main system of audio internal temperature sensor exports to display, by showing
Show device real-time displaying sound main frame temperature data outwardly and inwardly.Certainly, display can also work as temperature as alarm device
When abnormal occur, by modes such as flickers, user can be reminded.
Below, describe the working method of the automobile audio high temperature warning system of the present invention in detail.
The ambient temperature data of main system of audio external temperature sensor Real-time Collection main system of audio periphery, and by its turn
Change the signal of telecommunication into and input to main system of audio, then by the display in real time of this ambient temperature data over the display.Due to when outer
When portion's ambient temperature reaches 75 DEG C and continues more than 10 minutes, main system of audio internal components will be susceptible to fault.Therefore, when
When peripheral outer ambient temperature reaches 75 DEG C and continues 5 minutes, display arises that prompting interface, and speaker sends language simultaneously
Sound is pointed out, call user's attention, and the ambient temperature of main system of audio periphery has reached the normal operation circumstances of main system of audio
Temperature, user please confirm whether periphery has abnormal phenomena to occur, prompting user's main system of audio will automatic shutdown protection simultaneously.Sound
Ring main frame automatic shutdown within latter 5 minutes of warning.Certainly, because temperature sensor typically all can have error, in order to more preferable
Ground protection main system of audio it is also possible to when being arranged on temperature and reaching 70 minutes and continue 5 clock, just carry out related prompting, and in prompting 5
Main system of audio is closed within minute.
Meanwhile, the temperature data of main system of audio internal temperature sensor Real-time Collection main system of audio internal components, example
As monitor in real time is carried out to the temperature of the Primary Components such as power amplifier ic, power management module ic, central processing unit mcu, simultaneously by this
A little temperature datas show over the display.Under normal circumstances, when main system of audio external work environment temperature is less than 75 DEG C, sound equipment
Main frame internal components temperature typically not achieves the temperature that device can bear in itself.But break down exception in machine, such as
When radiator fan does not work, will result in internal components steep temperature rise, reaching the temperature range of itself normal work thus sending out
Raw fault is even damaged.For avoiding device failure, need in this case to carry out fault alarm.In the present invention, work as sound equipment
When main frame internal components temperature reaches internal preset temperature, fault alarm is carried out it is also possible to set by display interface and voice
Put automatic shutdown after a period of time of reporting to the police.Here, internal preset temperature can be arranged between 95-105 DEG C.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
