Description

Sharing bicycle monitoring devices that steadily rides

Technical Field

The utility model relates to a monitoring devices steadily rides of sharing bicycle belongs to the monitoring devices technical field that steadily rides.

Background

The main influencing factors of the riding stability of the bicycle are the rolling smoothness of the wheels and the smoothness of the rolling bodies in the axle, and when the vehicle passes through a ditch ridge, the impact of the road surface on the wheels can influence the steel rings of the wheels and the rolling bodies in the axle. When the number of times of accumulation becomes more later, the wheel will take place deformation, will be more laborious when riding, gives the experience of riding passerby extremely uncomfortable. When the user uses the sharing bicycle, the user does not pay much attention to protecting the sharing bicycle because of sharing, and the user cannot intentionally crawl or avoid when passing through the ditch bank. Based on the consideration, the vibration sensor is additionally arranged on the shared bicycle to monitor the vibration frequency of the bicycle, so that measures can be taken conveniently to remind a rider.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the above-mentioned practical application, the utility model provides a sharing bicycle monitoring devices that steadily rides guarantees the stationarity that sharing bicycle ridden.

The utility model discloses a solve its technical problem and adopt following technical scheme:

the vibration sensor module is used for continuously monitoring the vibration in the driving process of the shared bicycle and outputting a monitoring signal indicating the monitored vibration;

the controller is used for receiving the monitoring signal and judging whether the wheel vibration exceeds a threshold value;

the counter is used for accumulating the times that the vibration degree exceeds a threshold value;

and the output end of the wireless mobile communication module is connected with a background management system.

The vibration sensor module comprises a vibration sensor, a signal amplifier and a data acquisition card which are sequentially connected;

the vibration sensor is used for continuously monitoring the vibration magnitude in the running process of the shared bicycle and outputting a monitoring signal indicating the monitored vibration magnitude;

the signal amplifier is used for amplifying and denoising the monitoring signal of the vibration sensor and outputting the monitoring signal of the signal amplifier;

and the data acquisition card is used for collecting the monitoring signals from the signal amplifier, converting the collected monitoring signals from an analog signal form to a digital signal form and then outputting the converted monitoring signals to the controller.

The vibration sensor is at least one.

The controller comprises a data analysis processing unit and a microprocessor which are connected in sequence.

The device is used in cooperation with a mobile phone of a user.

The utility model has the advantages as follows:

the utility model discloses a sharing bicycle monitoring devices that steadily rides, vibration record through with the automobile body every time gets off, after a series of processings, the analysis vibration is to the influence of wheel, if probably cause the influence or cause the influence, with the aforesaid probably cause the influence or cause the vibration number of times of influence to add up, when the vehicle finishes using, on passing to user's cell-phone on the vibration number of times that will add up, and inform the user if accumulate certain number of times, when using the sharing bicycle of this brand next time, the expense of riding will rise, make to ride passerby and can protect sharing bicycle through such mode, reach extension sharing bicycle life's purpose.

Detailed Description

The invention is further elucidated with reference to the drawings and the detailed description. It should be understood that the following detailed description is illustrative of the invention only and is not intended to limit the scope of the invention.

Fig. 1 shows a structural schematic diagram of a shared bicycle lock loaded with a vibration monitoring device, the vibration monitoring device based on the riding stability of a shared bicycle is used in cooperation with a user mobile phone, and the structural schematic diagram comprises an original module in the shared bicycle lock structure and further comprises: the device comprises a vibration sensor module, a controller and a counter.

FIG. 2 shows a vibration sensor module of the vibration monitoring device, which includes a vibration sensor, a signal amplifier, and a data acquisition card.

In the working mode of the vibration sensor module in this embodiment, when a user starts to ride a bicycle after scanning a code, the vibration sensor starts to amplify and denoise a collected vibration signal by a signal amplifier and then transmit the amplified vibration signal to a data acquisition card, the data acquisition card converts a detection signal in an analog signal form into a monitoring signal in a digital signal form after recording, the monitoring signal is packed and transmitted to a controller, and data is transmitted once every time the data is received, so that the real-time performance of data transmission is realized.

Fig. 3 shows a schematic structural diagram of the vibration monitoring device, the controller receives the vibration monitoring signal acquired by the vibration sensor module after amplification and noise reduction from the data acquisition card, and the controller is internally provided with a data analysis unit and a microprocessor. The data analysis processing unit of the controller is used for receiving the data transmitted by the data acquisition card, processing the data and transmitting the processed data to the microprocessor; the microprocessor is used for receiving the processed information transmitted by the data analysis processing unit, making analysis judgment, and sending a pulse signal to the timer if the vibration degree exceeds a threshold value.

The timer receives the pulse signal sent by the controller, adds 1, and accumulates once every time the pulse signal is received. When the central control unit informs the background management system of locking the vehicle through the wireless mobile communication module as shown in fig. 1, the counter transmits the accumulated value to the background management system through the wireless mobile communication module.

Fig. 4 shows a work flow diagram of a vibration monitoring device according to an embodiment of the invention. When a user scans a code to ride a bicycle, the vibration sensor module starts to acquire vibration signals and transmits the vibration signals to the signal amplifier.

The square frame (processing and collecting) means that the signal amplifier receives vibration monitoring signals from the vibration sensor module, the vibration monitoring signals are amplified and subjected to noise reduction processing, then the vibration monitoring signals are transmitted to the data acquisition card, and the analog signal form is converted into a digital signal form and transmitted to the controller.

The judgment frame compares the vibration transmitted by the data acquisition card with a set threshold, if the vibration exceeds the set threshold, the microprocessor sends a pulse signal to the timer, and 1 is added when the timer receives the pulse signal; and if the vibration amplitude does not exceed the set threshold value, continuing judging the newly received vibration amplitude, and ending the operation when the shared bicycle finishes riding. And when the riding is finished, the accumulated value of the timer is sent to a background management system through the wireless mobile communication module.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and extensions can be made without departing from the principles of the present invention, and these improvements and extensions should also be regarded as the protection scope of the present invention.
