Abstract
The present invention discloses a kind of rotating speed of automobile engine detection system, including several speed probes being mounted on engine shaft, display module, data memory module, controller, and data comparing module inside controller, computing module, determining device, counting module are set, data comparing module is previously stored with normality threshold, and determining device is previously stored with judgment criteria.The present invention installs several speed probes on engine shaft, take the average value of several speed probes collected tachometer value in real time, it is compared with normality threshold pre-stored in controller, and judge automobile rotational speed whether in normality threshold, to judge whether automobile exceeds the speed limit, it is more more accurate than traditional detection system, and each speed probe works independently, it is independent of each other, even if some speed probe damages, still the normal operation of whole system, high reliablity are not influenced.
Description
Technical field
The present invention relates to automobile engine detection technique field, specifically a kind of rotating speed of automobile engine detection system.
Background technique
With the development and the improvement of people's living standards of society, car has become the essential friendship of people's daily trip
One of logical tool.For the sake of driving safety, China's traffic method clear stipulaties must not drive over the speed limit, but the behavior driven over the speed limit is still
So commonplace, this behavior can not only injure the personal safety of driver itself, also injure pedestrian and other vehicles
Safety.In China, there are thousands of traffic accidents daily, most of accident is all because of caused by driving over the speed limit.Although mesh
The preceding system for also having detection driving vehicle speed in the prior art, but accuracy in detection is not high, and error is larger, therefore, how quasi-
Really, the travel speed for efficiently detecting driving vehicle, the technical issues of becoming current urgent need to resolve.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of rotating speed of automobile engine detection systems, can
Rotating speed of automobile engine is accurately and efficiently detected, to detect the speed of automobile.
To achieve the goals above, the present invention provides a kind of rotating speed of automobile engine detection system, including is mounted on and starts
Several speed probes in machine shaft, display module, data memory module, controller, and be arranged in inside controller
Data comparing module, computing module, determining device, counting module, data comparing module are previously stored with normality threshold, and determining device is pre-
First it is stored with judgment criteria；Speed probe is transmitted to calculating mould for acquiring the tachometer value of shaft in real time, and by the tachometer value
Block, computing module are sent to comparing mould for calculating the average value for the tachometer value that the same second receives, and the average value
Block, data comparing module, the pre-stored normality threshold of rotary speed information and controller inside for arriving real-time reception carry out
It comparing, and comparison result is sent to determining device, determining device judgment criteria according to the pre-stored data provides judging result, and
It is shown on display module；Counting module, for adding up the number for the tachometer value that the same second receives, data memory module,
The judging result of the comparison result and determining device of comparison module for storing data.
Preferably, it there are four speed probe is arranged altogether, is mounted in the front and back shaft of automobile, each shaft is installed respectively
Two.
It further, further include the alarm module being connected with controller, alarm module includes LED warning lamp and buzzer, LED
Warning lamp is electrically connected with buzzer,
Preferably, display screen is LED display.
Preferably, warning lamp is light emitting diode.
Compared with prior art, the present invention installs several speed probes on engine shaft, takes several revolving speeds
The average value of sensor collected tachometer value in real time, is compared, and judge with normality threshold pre-stored in controller
Whether automobile rotational speed is in normality threshold out, thus judge whether automobile exceeds the speed limit, it is more more accurate than traditional detection system, and
Each speed probe works independently, and is independent of each other, even if some speed probe damages, does not still influence whole system
Normal operation, high reliablity.
Detailed description of the invention
Fig. 1 is electric functional block diagram of the invention.
Specific embodiment
Below with reference to embodiment and attached drawing, the invention will be further described.
As shown in Figure 1, a kind of rotating speed of automobile engine detection system of the present invention, including be mounted on automobile engine front and back and turn
Each two speed probes on axis, LED display, data memory module, alarm module, controller, and setting are controlling
Data comparing module, computing module inside device, determining device, counting module, data comparing module are previously stored with normality threshold,
Determining device is previously stored with judgment criteria, and alarm module includes warning lamp and buzzer, and warning lamp is electrically connected with buzzer, LED
Display screen is mounted on bridge control console.
Speed probe is transmitted to computing module for acquiring the tachometer value of shaft in real time, and by the tachometer value, calculates mould
Block is sent to data comparing module, data ratio for calculating the average value for the tachometer value that the same second receives, and the average value
To module, for by real-time reception to rotary speed information be compared with normality threshold pre-stored inside controller, and will
Comparison result is sent to determining device, and determining device judgment criteria according to the pre-stored data provides judging result, and on the display module
It shows；Counting module for adding up the number for the tachometer value that the same second receives, and is sent to computing module and data are deposited
Store up module, data memory module, for storing data, in case data are inquired and analyzed later.
Judgment criteria are as follows: it is that determining device provides the result is that normal when revolving speed average value is in normality threshold, when revolving speed is average
Value is that determining device provides the result is that abnormal not in normality threshold.The judging result that controller is provided according to determining device, control
Alarm module work or do not work, when the judging result that determining device provides be it is normal, alarm module does not work, when determining device provides
Judging result be it is abnormal, controller controls alarm module work, issues alarm, while warning lamp is lit, and prompting is driven
The person's of sailing automobile speed exception.This system structure is simple, and detection accuracy is high, and detection speed is fast.
