摘要： The invention relates to an online measurement system and method for multiple parameters of a wheel based on structured light. The measurement system comprises a wheel sensor (10), a first wheel online measurement device (20) and a second wheel online measurement device (30), and is characterized in that both the first wheel (20) online measurement device and the second wheel online measurement device (30) comprise a tread structured light unit (21), a profile structured light unit (22) and a two-dimensional image sensor (23). The tread structured light unit (21) and the profile structured light unit (22) project a profile contour curve and a tread contour curve on the wheel, the two-dimensional image sensor (23) takes images, three-dimensional reconstruction is performed on the images to obtain tread contour information and profile contour information, and the wheel diameter, the wheel flange height and the wheel flange thickness are acquired according to the obtained contour information. The online measurement system is high in reliability and measurement accuracy, and reduces influences of the external ambient light. The online measurement system can also solve the wheel diameter according to two profile structured light contour fitting circles on the same circle, so that precise positioning for the wheel is not required.

摘要： The present invention discloses a built-in tire pressure monitoring and alarming device. A housing (1) is provided therein with a reference chamber (4) and an inlet pipe (402) extended from the reference chamber (4) to a valve stem (2), and a reference chamber valve (7) capable of sealing and opening the inlet pipe (402) is mounted within the inlet pipe (402). A throttle core (702) of the reference chamber valve (7) is directly resisted against a core bar (301) of a throttle core (3). During the tire is inflated, the throttle core (3) is pushed open, the core bar (301) of the throttle core (3) is pushed against the valve core (702), and then the reference chamber valve (7) is opened so that the reference chamber (4) is inflated. After the inflation is accomplished, the throttle core (3) is restored and the reference chamber valve (7) is closed so that the reference chamber (4) is sealed. When the pressure within a tire is too low, an elastic metal diaphragm (401) on the wall of the reference chamber will generate an outward deformation due to the difference in pressure; and, when the deformed metal diaphragm comes into contact with the anode contact of an alarming signal transmitting module (5), the alarming signal transmitting module (5) is powered on and sends a signal, and then the alarming device on a vehicle receives the signal and gives an alarming. The alarming device is of mechanical sensing and is stable and reliable in operation, and thus capable of functioning in severe working environments; furthermore, the alarming device has the advantages of low failure rate and relatively low cost.
