And the failure of engine is solved, enable automobile normally travel, detected it is not necessary that vehicle is checked maintenance store, is effectively saved
Cost and time.
Detailed description of the invention
Fig. 1 is invention's principle block diagram.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
9 diameter of the present embodiment top plate presplit blasting hole is 89mm, hole depth 35m.
As shown in Figure 1, a kind of Portable automobile engine wireless detection device of the present invention, including shell, surface of shell peace
Equipped with solar panel and display screen, inside is equipped with controller and warning circuit, and controller is internally provided with reception signal
Radio receiving unit, the coffret of controller is electrically connected with the input terminal of warning circuit；Further include speed probe, is used for
It detects the revolving speed of engine and obtains a tachometer value, water temperature sensor, for detecting the water temperature of engine and obtaining a temperature value,
Audio sensor, for detecting audio when engine is run and obtaining an audio value, oil pressure sensor, for detecting engine
Engine oil pressure and obtain an oil pressure force value, above-mentioned each sensor internal is separately installed with wireless sending module, will test
Signal radio receiving unit is sent to by wireless sending module, the signal received is sent to control again by radio receiving unit
Device processed, above-mentioned each sensor are both placed in shell；
