Detailed Description
The embodiment of the utility model provides a through providing a bluetooth car race scale, solved and looked over the technical problem that the car racing weighing data is inconvenient and the consumption is big among the prior art, realized the convenient low-power consumption's that weighs technical effect.
The embodiment of the utility model provides an in technical scheme for solving above-mentioned problem, the general thinking is as follows: set up bluetooth module, bluetooth module and mobile terminal are connected the back of success, and weight sensor just begins to detect weight, and bluetooth module and mobile terminal are connected failure or disconnection back, and weight sensor stops detecting weight to practice thrift the consumption better.
For better understanding of the above technical solutions, the following detailed descriptions will be provided in conjunction with the drawings and the detailed description of the embodiments.
Referring to fig. 1-4, the preferred embodiment of the bluetooth racing car scale of the present invention.
The utility model discloses a: a top plate 1 for placing a tire of a racing car; a bottom plate 2 located below the top plate 1; the soleplate 2 is placed on the ground. A weight sensor 3 provided between the top plate 1 and the bottom plate 2; the weight sensor 3 detects the weight exerted by the wheel tyres of a racing car on the roof 1.
The MCU4 is electrically connected with the weight sensor 3; the weight sensor 3 is connected with the MCU4 through the A/D converter 5. The A/D converter 5 converts the weight analog signal collected by the weight sensor 3 into a digital signal and sends the digital signal to the MCU 4.
The Bluetooth module 6 is electrically connected with the MCU 4; after the Bluetooth module 6 is in communication connection with an external mobile terminal, weighing data transmitted by the MCU4 is received and sent to the mobile terminal; the mobile terminal is specifically a smart phone, a tablet computer, a notebook computer and the like. The power module 7 is electrically connected with the MCU4 and the Bluetooth module 6; the power module 7 supplies power, and the MCU4 controls whether or not power is supplied to the weight sensor 3.
