Description
Technical Field
The invention relates to the field of power battery replacement of electric coaches, in particular to a self-adaptive vehicle passing control method for sharing power replacement of multi-vehicle type electric coaches.
Background
With the shortage of global energy, the problem of environmental pollution is becoming more serious, and under the large trend of environmental protection and clean energy concept, the electric passenger car has a very wide development prospect because the influence on the environment is smaller than that of the traditional car. The electric motor coach is a coach which takes a vehicle-mounted power supply as power and drives wheels to run by a motor, and meets various requirements of road traffic and safety regulations. The power battery is the core of the electric motor coach, but the insufficient cruising ability of the power battery is the bottleneck troubling the development of the electric motor coach.
The operation mode that the power battery is not required to be charged and only the electric vehicle is reloaded with the power battery full of electric power appears now, so that the time for a user to wait for charging the power battery is shortened, the time is basically the same as the time for refueling the traditional automobile, and the habit of the user for using the automobile does not need to be changed. A quick-change mode: the small electric motor coach running into the battery replacement station directly replaces the charged power battery through the battery replacement equipment in the battery replacement station, so that the small electric motor coach with the power battery of the small electric motor coach with insufficient electric quantity is convenient and quick, but the battery replacement technology is not mature.
In the battery replacement mode, the power battery is arranged on the body of the electric motor coach, the size of the power battery is large (the length and the width are several meters generally) and the weight of the power battery is large (several hundred kilograms), and the safety requirement on the battery replacement mode is high; and the wheelbase and the wheel base of the electric motor coach of different models are different, even the size of the power battery is different, the current power exchange device in the power exchange mode is mainly suitable for the electric motor coach of a single model, the power battery of the electric motor coach of other models with different wheelbase/different wheel base can not be replaced, and under the concept of global new energy vehicle construction, the power battery of the electric motor coach of a single model can only be replaced, which is a great waste of resources.
Meanwhile, the power battery is heavy, so that the working strength is too high due to manual movement. At present, the mechanical mode is adopted for movement, and the corresponding driving equipment is large in size due to the weight of the power battery, occupies a large space, and is not beneficial to the arrangement of the whole battery replacement equipment. In addition, the replacement of the power battery also requires precise walking positioning and relative displacement adjustment, which are not achieved by the existing replacement equipment.
In current trade electrical equipment, because the current of vehicle is mostly ground walking, consequently the trade electrical walking equipment of bottom need be at bottom mounting rail and excavation pit (the excavation is now about 1.8 meters, and the construction degree of difficulty is too high), but a lot of trade power stations can't carry out too deep excavation, in order to save the space of trading the power station and trade the ground cost of power station construction in earlier stage, must have the relatively convenient trade electrical equipment to solve this difficult problem.
Therefore, a new technical scheme of the battery replacement equipment with a vehicle passing structure is needed at present, and the problem that various electric cars with different wheel pitches and different wheel base can smoothly pass through the pit of the battery replacement robot under the condition that the whole battery replacement station does not need to be dug too deeply is solved.
Disclosure of Invention

In order to solve the problems, the invention provides a self-adaptive vehicle passing control method for sharing and replacing batteries of multi-vehicle type electric buses, which comprises the following steps:
after an electric passenger car approaches to the intelligent battery replacement positioning platform, a vehicle identification device of the intelligent battery replacement positioning platform acquires vehicle type parameter information of the electric passenger car;
the intelligent electricity-exchanging positioning platform is used for positioning the vehicle after the small electric passenger car stably passes through the translation bridge plate and the translation suspension bridge;
after the electric motor coach is positioned on the intelligent battery replacement positioning platform, the translation suspension bridge moves upwards in the z direction and leaves a space, so that the battery replacement robot enters the lower part of the intelligent battery replacement positioning platform to perform battery replacement operation on the electric motor coach.
Compared with the prior art, the pit digging device can enable various electric coaches with different wheel distances and different wheel base distances to stably pass through the digging pit of the battery replacing robot, can ascend in the Z direction through the vertical Z-direction moving unit, can make a space, enables the battery replacing robot carrying the power battery to pass through, reduces the depth of an initial foundation pit of the battery replacing station (the original foundation pit is 1.8 m, the construction difficulty is too high), and the current pit digging depth is 55cm, so that the construction difficulty is reduced, the construction cost of the battery replacing station is reduced, and the large-scale commercial popularization of the electric coaches is facilitated.
