Abstract
The present invention relates to a flat zero velocity forbidden electric braking controller for regenerative feedback type electric braking electric cars, which is composed of an extremum controller, a zero velocity detector, a set trigger and a control gate. On the basis of setting a limit value and a zero velocity reference value, after an actual value of the running velocity of an electric car and an electric braking master control signal are collected in real time, the real-time online discrimination of the historical process relationship of the flat zero velocity and the electric braking master control signal is realized through a full digital type data discrimination structure, and whether the electric car realizes the electric braking in a flat zero velocity state is controlled. The present invention is a requisite special functional component for regenerative feedback type electric braking variable frequency driven electric cars to obtain good control function and control characteristic, and can avoid the phenomenon that when the electric braking is added to a car in the flat zero velocity state, the car stops after backflow. The present invention optimizes the control function of a control system of the electric car.
Description
Technical field
The present invention relates to electronic applications, especially relate to sensor-based system, particularly vehicle-state discriminating gear, concrete is a kind of be used for regenerative feedback type electric brake tram forbid level land zero-speed electric brake controller.
Background technology
In the prior art, the DC chopped-wave type of drive is adopted in the driving of city trackless or tramway train, can't realize the regeneration feed-back type electric braking, there is not real-time online to differentiate the technology of the historical process relation of level land zero velocity and electric braking master order yet, and the AC frequency conversion of band regeneration feed-back type electric braking drives electric car, under the zero-speed quiescence of level land, when adding electric braking, the problem that impact plugging moment can occur and stop after vehicle is flow backwards again influences safety.
Summary of the invention
Technical matters of the prior art to be solved by this invention is: because in the prior art, the AC frequency conversion of band regeneration feed-back type electric braking drives electric car, under the zero-speed quiescence of level land, when adding electric braking, the problem that impact plugging moment can occur and stop after vehicle is flow backwards again influences safety.
The technical scheme that the present invention is adopted for solution above-mentioned technical matters of the prior art provide a kind of be used for regenerative feedback type electric brake tram forbid level land zero-speed electric brake controller, described this be used for regenerative feedback type electric brake tram forbid that level land zero-speed electric brake controller is by the extreme value detector, the zero-speed detector, first set flip-flop, second set flip-flop, first control gate and second control gate constitute, wherein, the mouth of described extreme value detector is connected with the input end of described first control gate and second control gate, the mouth of described first control gate is connected with the input end of described first set flip-flop, the mouth of described first set flip-flop is connected with the input end of described second control gate, the mouth of described second control gate is connected with the input end of described second set flip-flop, the mouth of described zero-speed detector respectively with described first control gate, the input control end of second control gate and first set flip-flop is connected.
Further, described extreme value detector and zero-speed detector are the absolute value comparators.
Further, described set flip-flop is a rest-set flip-flop.
Further, described control gate is a logic gates.
Further, the input end of described extreme value detector makes signal pickup assembly be connected with the electric braking master, the enforcement state of the online differentiation electric braking of described extreme value detector master order, the input end of described zero-speed detector is connected with electric car actual measurement speed signal harvester, the online differentiation vehicle of described zero-speed detector zero-speed state, the level land zero-speed of described extreme value detector and described zero-speed detector on-line monitoring vehicle and the relation of the historical process between the electric braking master value of order, thereby judge the succession of level land zero-speed state and electric braking, at the mouth output high level signal or the low level signal of second set flip-flop.
Principle of work of the present invention is: the incoming signal of extreme value detector is for the outside electric braking master order that collects and differentiate extreme value, the enforcement state of the online differentiation electric braking of described extreme value detector master order, the incoming signal of zero-speed detector is outside electric car actual measurement speed and the zero-speed a reference value that collects, the online differentiation vehicle of described zero-speed detector zero-speed state, the mouth of described extreme value detector is connected to the input end of first control gate and second control gate, the mouth of described first control gate is connected to the input end of first set flip-flop, the mouth of described first set flip-flop is connected to the input end of described second control gate, the mouth of described second control gate is connected to the input end of second set flip-flop, the mouth of described zero-speed detector is connected to described first control gate respectively, the input control end of second control gate and first set flip-flop.In the application process, on the basis that provides limit and zero-speed a reference value data, by photoelectric encoder on the traction motor axle and the main order of pedal brake, gather electric car running velocity actual value and the electric braking master value of order in real time, according to the level land zero-speed of monitoring and the historical process relation of the electric braking master value of order, by full digital discriminating data structure, whether control level land zero-speed state realizes electric braking.If electric car owing to realize electric braking earlier, makes speed drop to zero in when operation, if this moment, the electric braking master made signal exist, the second set flip-flop output low level then, electric car keeps the electric braking state to stop.If electric car originally was in level land zero-speed state, make signal even add the electric braking master this moment, second set flip-flop output high level, forbid electric car realization electric braking, avoid owing to impact plugging moment makes the phenomenon of stopping again after the vehicle refluence, optimize the controllable function of electric car control system, and save unnecessary waste of power.
Absolute value comparator described in the present invention, rest-set flip-flop and logic gates are the electrician trade known technology, do not repeat them here.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention can onlinely judge the historical process relation of level land zero-speed and the electric braking master value of order effectively by the discriminating data structure of full digital, thereby judge the succession of level land zero-speed state and electric braking, thereby whether control vehicle realizes electric braking under the zero-speed state of level land, so just can avoid owing to impact plugging moment makes the phenomenon of stopping again after the vehicle refluence, optimize the controllable function of electric car control system, and save unnecessary waste of power.
Purpose of the present invention, feature and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
