Chip receives the enabling signal, and the motor 4 is controlled to rotate.
Through the above technical solutions, when user needs to build detection environment, it is only necessary to by shell 1 to there is provided pedestals 5
Side tilt on the lower, angle induction mechanism 6 can detect inclined direction automatically, and then motor 4 starts to rotate, drive
Stent 51 rotates auto-extending shell 1 and supports shell, and when the inclination separate backwards to ground of shell 1, motor 4 will be opposite
It rotates backward, such stent 51 will be retracted into shell 1, and so there is no need to artificial driving motors 4, can realize intelligence
Can pedestal 5 build, it is more intelligent, so as to build more convenient rapid during detection environment, further reduce people
The process of work operation, is more convenient for the operation of user, avoids extra operation, improve work efficiency.
As a kind of improved specific embodiment, the angle induction mechanism 6 includes liquid storage shell 61,62 and of conduction liquid
First terminals 63 and the second terminals 64, the conduction liquid 62 are stored in liquid storage shell 61, first terminals 63
The shell bottom of liquid storage shell 61 is fitted in, and is bonded with adjacent one side wall, and be dipped in conduction liquid 62, second wiring
End 64 fits in shell top, and one side wall be bonded with the first terminals 63 is bonded, when the liquid storage shell 61 is to the first wiring
When holding the sidewall direction of 63 fittings on the lower, 62 liquid level of conduction liquid tilts and contacts the second terminals 64, and then makes first to connect
63 and second terminals 64 of line end communicate, and the side wall that the first terminals 63 are bonded on the liquid storage shell 61 is fitted in shell 1
On one side relative to pedestal 5.
Through the above technical solutions, when user is only by shell 1 to there is provided the inclination of the side of pedestal 5 on the lower, liquid storage shell
61 will can also tilt with inclination, in this way its internal conduction liquid 62, the second terminals 64 can thus also touched and leads
Electro-hydraulic 62, such first terminals 63 will be connected with the second terminals 64, thus can in this way be connected with transmission start signal
Main control chip can receive the enabling signal of its transmission afterwards, and main control chip control motor 4 can thus be utilized to rotate, and
And when the first terminals 63 are not connected with the second terminals 64, main control chip would not receive enabling signal, thus again
Motor 4 can be controlled to rotate backward, and then pedestal 5 is retracted to inside shell 1, it is such simple and practical in structure, it does not need to adopt
With angular transducer, such as MPU6050 integration modules in this, the process of posture calculation is also avoided in this way, is thus reduced
To the performance requirement of main control chip, cost is thereby reduced.
