Abstract
The utility model discloses a differential motor rotation speed detection device which belongs to the technical field of measurement and testing devices. The differential motor rotation speed detection device comprises two rotation speed sensors, a data acquisition device, a data comparator, a controller, a warning lamp and a wireless transmission module. The two rotation speed sensors are respectively arranged on left and right wheels of a vehicle. The two rotation speed sensors are electrically connected with the data acquisition device. The data acquisition device is electrically connected with the data comparator which is used for comparing acquisition signals. The data comparator is electrically connected with the controller. The warning lamp and the wireless transmission module are electrically connected with the controller. The data acquisition device, the data comparator, the controller and the wireless transmission module are arranged in a dashboard of the vehicle. The warning lamp is arranged on the surface of the dashboard. The differential motor rotation speed detection device has the advantages that the rotation speed of the wheels on left and right sides of the vehicle can be detected in real time; the working condition of a differential motor is determined according to the rotation speed of the wheels on left and right sides of the vehicle; and alarm and remote informing can be carried out.
Description
Technical field
The utility model relates to a kind of differential speed motor speed detector, belongs to measure the proving installation technical field.
Background technology
Differential speed motor is used for electric automobiles more, is electric motor car driving and gearing, the main part of motorized motions sedan-chair, the centre that is positioned at drive axle by gear to both sides semiaxis transferring power.Allow the both sides semiaxis with different rotating speed rotations, satisfying two sidecar wheels does equidistantly not travel with the form of pure rolling as far as possible, reduce the friction on tire and ground, if differential speed motor breaks down, two sidecar wheels are not when work equidistantly travels, vehicle tyre will produce strong friction with ground so, and the time one is of a specified duration, and vehicle tyre will serious wear.
The driver differed and in time knows failure message surely when differential speed motor broke down, differential speed motor is in the fail operation state for a long time can cause more severe impairment to differential speed motor undoubtedly, as can not on-call maintenance, differential speed motor might just can't be repaired, and has had only the differential speed motor that more renews.
Summary of the invention
Problem at above-mentioned prior art existence, the utility model provides a kind of differential speed motor speed detector, detect in real time the rotating speed of vehicle the right and left wheel, judge the duty of differential speed motor according to the rotating speed of left and right vehicle wheel two sidecar wheels, can report to the police and long-range informing.
To achieve these goals, the technical solution adopted in the utility model is: a kind of differential speed motor speed detector, comprise two speed probes, data acquisition unit, data comparator, controller, warning lamp and wireless transport module, two speed probes are installed in respectively on the left and right wheels of vehicle, two speed probes are electrically connected with data acquisition unit, data acquisition unit is electrically connected with the data comparator that is used for relatively gathering signal, data comparator is electrically connected with controller, warning lamp and wireless transport module are electrically connected with controller, data acquisition unit, data comparator, controller and wireless transport module are installed in the panel board inside of vehicle, and warning lamp is installed in the surface of panel board.
Controller is single-chip microcomputer.
Principle of work: be installed in the rotating speed that speed probe on the left and right vehicle wheel wheel detects the vehicle left and right wheels in real time, data acquisition unit is gathered speed probe and is detected the data that obtain and transfer data to data comparator, data comparator compares analysis to data, comparative result is transferred to controller, if comparative result shows differential speed motor and is in malfunction, then controller can control warning lamp report to the police control simultaneously wireless transport module just the failure message of fault differential speed motor be transferred to differential speed motor producer.
The beneficial effects of the utility model are: the wheel on the left and right vehicle wheel both sides is installed speed probe, detect the rotating speed of vehicle the right and left wheel in real time, according to the duty that detects the data judging differential speed motor, when judging that differential speed motor is in malfunction, controller can be controlled warning lamp and report to the police, wireless transport module also can be transferred to the failure message of fault differential speed motor differential speed motor producer simultaneously, so that producer can safeguard the fault differential speed motor by on-call maintenance.
Description of drawings
Fig. 1 is electric theory diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, this differential speed motor speed detector, comprise two speed probes, data acquisition unit, data comparator, controller, warning lamp and wireless transport module, two speed probes are installed in respectively on the left and right wheels of vehicle, two speed probes are electrically connected with data acquisition unit, data acquisition unit is electrically connected with the data comparator that is used for relatively gathering signal, data comparator is electrically connected with controller, warning lamp and wireless transport module are electrically connected with controller, data acquisition unit, data comparator, controller and wireless transport module are installed in the panel board inside of vehicle, and warning lamp is installed in the surface of panel board.
Two speed probes are installed in respectively on the left and right wheels of vehicle, are used for detecting respectively the rotating speed of vehicle left and right wheels;
Two speed probes of data acquisition unit collection detect the left and right vehicle wheel wheel speed signal that obtains, and then tach signal is transferred to data comparator compares analysis, under the normal travel situations, the left and right vehicle wheel wheel speed is identical, when vehicle two sidecar wheels are done equidistantly not travel, if the left and right vehicle wheel wheel speed is still identical, prove that then differential speed motor is in malfunction;
Data comparator is transferred to controller with the fault data signal results that comparative analysis goes out;
Controller can be controlled warning lamp and report to the police, can in time remind the duty of the current differential speed motor of vehicle drive personnel, for safeguarding that in time differential speed motor provides foundation, simultaneously controller also can be controlled wireless transport module the failure message of fault differential speed motor is transferred to differential speed motor producer, and the Product Status of selling away also can in time be known according to the wireless transport module information transmitted in differential speed motor producer.
In order to guarantee the controller stability in when work, controller is single-chip microcomputer.
