A kind of temperature monitoring method for automobileTechnical field
The invention belongs to automotive temp monitoring fields, more specifically more particularly to a kind of monitoring temperature for automobileSystem.Meanwhile the invention further relates to a kind of temperature monitoring methods for automobile.
Background technique
Automobile long descending section when driving, vehicle gives it the gun under gravity, for guarantee automotive safety it is steadyDescending, automobile should have certain brake force, however as the increase of length of grade, brake friction heating, so that brake efficiencyIt reduces.Under normal circumstances, when brake temperature reaches 200 DEG C, braking deceleration is decreased obviously, and it is existing brake-fade occurAs；When brake temperature is more than 600 DEG C, braking deceleration leads to brake fade close to zero.Therefore, automobile is in long descendingIt is very necessary to brake temperature real-time monitoring when sections of road.The monitoring method of traditional automobile brake drum is usuallyOne temperature sensor is installed on the brake drum of automobile, it is then by conducting wire or wireless communicator that it is indoor with drivingThe connection of human-computer exchange device, understands the temperature of brake drum in real time in this way convenient for driver.Although it can understand brake drum in real timeTemperature, but there is no too big use helping driver preferably to travel this respect.
Summary of the invention
The purpose of the present invention is to provide a kind of temperature monitoring methods for automobile, to solve to mention in above-mentioned background techniqueOut the problem of.
To achieve the above object, the invention provides the following technical scheme:
A kind of temperature monitoring system for automobile, including GPS positioning module, velocity sensor, gyroscope, temperature acquisition mouldBlock, signal processing module, wireless communication module, data conversion module, central processing unit and human-machine exchange module, the GPS are fixedPosition module, velocity sensor, gyroscope, temperature collecting module are electrically connected by conducting wire and signal processing module, the signalModule is connect processing module with data conversion module by wireless communication, and the central processing unit passes through conducting wire and data conversion mouldBlock, human-machine exchange module electrical connection.
A kind of temperature monitoring method of automobile, includes the following steps:
S1, data acquisition: the location information of vehicle is acquired by GPS positioning module first, then by velocity sensor comeThe velocity information for acquiring vehicle, then acquires the temperature of automobile brake drum, finally by gyroscope by temperature collecting moduleThe acceleration of automobile and the gradient of road are measured, after being handled by signal of the signal processing module to each sensor,Module is sent at data conversion module by wireless communication, be sent to after data conversion module is converted at central processing unit intoRow processing；
S2, data processing: the temperature of the brake drum of temperature collecting module different periods collected is stored first, thenThe speed of its vehicle measured with the gradient of the pickup and road that are measured by gyroscope, velocity sensor is carried out pairThan, thus it will be seen that when automobile is braked at various speeds brake drum temperature variations, and on different slopesSpend the temperature variations of brake drum when lower automobile is braked；
S3, data analysis: by human-machine exchange module, driver is recognized that automobile in different gradient and the feelings of friction speedAfter being braked under condition, the temperature variations of automobile brake drum, such driver can be according to GPS during drivingLocating module, velocity sensor, gyroscope, information used by temperature collecting module select suitable brake modes and brakeSpeed, the brake modes for having the selection being directed to different in different road conditions in this way, so that it may effectively avoid because of brake modesNot to caused by, automobile brake drum temperature rises too fast problem.
Compared with prior art, the beneficial effects of the present invention are: the present invention passes through setting GPS positioning module, velocity pick-upDevice, gyroscope, temperature collecting module can the speed to automobile, the gradient when driving, descending when acceleration and brake drumTemperature be monitored, by comparison it will be seen that when descending, friction speed and different gradient are to automobile brake drum temperature changeInfluence effectively prevent automobile system so that driver can select suitable drive manner according to different road conditionsThe too fast problem of dynamic drum heating.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, to thisInvention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, notFor limiting the present invention.
A kind of temperature monitoring system for automobile, including GPS positioning module, velocity sensor, gyroscope, temperature acquisitionModule, signal processing module, wireless communication module, data conversion module, central processing unit and human-machine exchange module, the GPSLocating module, velocity sensor, gyroscope, temperature collecting module are electrically connected by conducting wire and signal processing module, the letterModule is connect with data conversion module by wireless communication for number processing module, and the central processing unit passes through conducting wire and data conversionModule, human-machine exchange module electrical connection.
A kind of temperature monitoring method of automobile, includes the following steps:
S1, data acquisition: the location information of vehicle is acquired by GPS positioning module first, then by velocity sensor comeThe velocity information for acquiring vehicle, then acquires the temperature of automobile brake drum, finally by gyroscope by temperature collecting moduleThe acceleration of automobile and the gradient of road are measured, after being handled by signal of the signal processing module to each sensor,Module is sent at data conversion module by wireless communication, be sent to after data conversion module is converted at central processing unit intoRow processing；
S2, data processing: the temperature of the brake drum of temperature collecting module different periods collected is stored first, thenThe speed of its vehicle measured with the gradient of the pickup and road that are measured by gyroscope, velocity sensor is carried out pairThan, thus it will be seen that when automobile is braked at various speeds brake drum temperature variations, and on different slopesSpend the temperature variations of brake drum when lower automobile is braked；
S3, data analysis: by human-machine exchange module, driver is recognized that automobile in different gradient and the feelings of friction speedAfter being braked under condition, the temperature variations of automobile brake drum, such driver can be according to GPS during drivingLocating module, velocity sensor, gyroscope, information used by temperature collecting module select suitable brake modes and brakeSpeed, the brake modes for having the selection being directed to different in different road conditions in this way, so that it may effectively avoid because of brake modesNot to caused by, automobile brake drum temperature rises too fast problem.
For the present invention by setting GPS positioning module, velocity sensor, gyroscope, temperature collecting module can be to automobileThe temperature of acceleration and brake drum when speed, the gradient when driving, descending is monitored, by comparison it will be seen that descendingWhen, the influence of friction speed and different gradient to automobile brake drum temperature change, so that driver can be according to differentRoad conditions select suitable drive manner, effectively prevent automobile brake drum and heat up too fast problem.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and itsInventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
