Embodiment Construction

[0016] Below in conjunction with example the present invention will be further described:

[0017] figure 1 It is a functional block diagram of the present invention. The monitoring device of the present invention includes an acceleration sensor, a differential amplifier circuit, a V-f converter, a waveform generator, a digital frequency comparator, a buzzer and a counter. The monitoring devices are divided into two groups, longitudinal and lateral, respectively monitoring the longitudinal and lateral acceleration changes of the bus. Among them, the V-f converter includes an integrator and a comparator, adopts a voltage control frequency method, and the output pulse number is proportional to the input voltage. The comparison circuit of the digital frequency comparator includes two input terminals, and the waveform generated by the waveform generator is connected to the lower input terminal as a reference signal.

[0018] like figure 2 As shown, in the tensioned wire type ...

Abstract

The invention discloses a bus riding comfort monitoring device based on acceleration change so as to urge a driver to reduce discomfort caused by rapid acceleration change brought by senseless acceleration, deceleration, overtaking, cut back and the like from the view of driving. The monitoring device comprises an acceleration sensor, a difference amplifier, a V-f convertor, a waveform generator, a digital frequency comparator, a buzzer and a counter. The significance of the invention lies in that the monitoring device not only can remind the driver to improve driving quality during the driving course of the bus, but also takes the data display of the counter as a basis for evaluating the riding comfort of the bus and feeds the data back to the driver so as to improve the riding comfort in the course of driving.

Description

Technical field: [0001] The invention relates to a monitoring device for indicating the comfort level of a vehicle by using the change of the acceleration in the longitudinal direction and the lateral direction of a certain place in the bus. Background technique: [0002] Encouraging public transportation is an important measure to deal with the energy crisis and build a harmonious society. Because the bus company usually only assesses the number of trips of the drivers, it is difficult to quantitatively assess the driving quality, resulting in the artificial deterioration of the bus ride comfort. Therefore, it is particularly necessary to improve and improve the ride comfort of the bus. According to the relevant research and test data of ride comfort, discomfort is caused by physical vibration in a specific environment affecting the whole body, namely longitudinal acceleration, lateral acceleration, vertical acceleration, roll angular velocity, roll angular acceleration, l...
