Background

The upper motor is a main power source for the pure electric sanitation vehicle to implement sanitation operation, and the normal operation of the upper motor needs to be matched with a proper upper motor controller.

The integrated motor controller is widely applied to a pure electric sanitation vehicle due to the advantages of volume, weight, cost and reliability, and the current integrated motor controller is generally composed of different combinations of a steering motor controller, an air compressor motor controller, a driving motor controller, DC/DC and high-voltage power distribution. The steering or air compressor motor controller in the integrated motor controller is used as the upper motor controller to control the operation of the upper motor so as to provide power for an oil pump or a water pump of an upper system. However, when the power of the upper-mounted motor is increased or the voltage platform of the vehicle is low, the rated current of the upper-mounted motor is often increased to more than 20A, but the steering of the current integrated motor controller or the rated current of the motor controller of the air compressor is small, usually only 10 to 15A, the oil pump or the upper-mounted motor of the water pump cannot be driven to continuously operate, and only a single upper-mounted motor controller with large capacity can be adopted, so that the problems of high number of controllers in the vehicle, large capacity redundancy, correspondingly high cost, many high-voltage nodes and complex system can be caused.

Detailed Description

Sanitation vehicle embodiment

The embodiment provides a sanitation vehicle, which takes a pure electric sanitation vehicle as an example, and of course, the sanitation vehicle can also be a hybrid power sanitation vehicle. The sanitation truck is provided with a loading motor parallel control system to realize the control of the loading motor. Since other components of the sanitation vehicle are not the point of the claimed sanitation vehicle, detailed description is omitted here.

The upper-mounted motor parallel control system comprises an integrated motor controller and an upper-mounted motor, the integrated motor controller can be a three-in-one or even one-in-one controller commonly used by new energy vehicles, and comprises at least two motor controllers, the two motor controllers are respectively a first motor controller and a second motor controller, and the capacity of the single motor controller does not meet the continuous long-term operation of the upper-mounted motor. The high-voltage output interface of the first motor controller and the high-voltage output interface of the second motor controller are in output connection with the high-voltage input interface of the upper motor, so that the two motor controllers in the integrated motor controller run in parallel to meet the power requirement of the upper motor.

Because the motor controller in the integrated motor controller usually comprises a steering motor controller and an air compressor motor controller, and the rated current range of the upper motor is 20-30A, and the rated currents of the steering motor controller and the air compressor motor controller are both about 15A, in order to realize current matching, in the embodiment, the first motor controller takes the steering motor controller as an example, the second motor controller takes the air compressor motor controller as an example, and the high-voltage output interface of the steering motor controller takes the three-phase high-voltage output interface as an example, and outputs three-phase alternating current; the high-voltage output interface of the air compressor motor controller takes a three-phase high-voltage output interface as an example, and outputs three-phase alternating current. Accordingly, the upper motor may be a three-phase asynchronous motor or a permanent magnet synchronous motor.

To any one motor controller in steering motor controller and the air compressor machine motor controller, can not be simultaneously for facial make-up motor and the motor power supply that corresponds, for example: the steering motor controller does not simultaneously power the upper motor and the steering motor. The steering motor controller or the air compressor motor controller in the integrated motor controller supplies power to the power-assisted steering oil pump high-voltage alternating current motor and the air compressor high-voltage alternating current motor at first, and because a part of pure electric sanitation vehicles adopt the low-voltage direct-current 24V power-assisted steering motor and the vacuum pump motor, the low-voltage direct-current 24V motors cannot supply power to the steering motor controller or the air compressor motor controller, the steering motor controller and the air compressor motor controller in the integrated controller are in an idle state, and the sanitation vehicles usually comprise the upper motor, so the steering motor controller or the air compressor motor controller of the integrated controller can be used for controlling the upper motor.

The junction box of the upper motor comprises two high-voltage input interfaces, a three-phase high-voltage output interface of the steering motor controller is connected with one of the high-voltage input interfaces through a three-phase output high-voltage wire, a three-phase high-voltage output interface of the air compressor motor controller is connected with the other high-voltage input interface through a three-phase output high-voltage wire, and each phase wiring terminal of UVW three-phase high-voltage wires of the two motor controllers is connected to a corresponding wiring terminal in UVW three phases of the upper motor. As shown in fig. 1, the steering motor controller and the air compressor motor controller simultaneously output three-phase power to the upper motor, and the current of the upper motor is the sum of the currents of the two motor controllers. The rated current range of the motor mounted on the sanitation truck is 20-30A, the rated currents of the steering motor controller and the air compressor motor controller are both 15A, and the total rated current is increased to 30A by connecting the steering motor controller and the air compressor motor controller in parallel, so that the power requirement of the motor mounted on the sanitation truck is met.

The upper motor is provided with a rotating speed detection module and a temperature detection module which are respectively used for detecting the rotating speed of the motor and the temperature of the motor, the rotating speed detection module and the temperature detection module are connected with the integrated motor controller through corresponding signal transmission lines, rotating speed and temperature information during the operation of the upper motor can be fed back to the integrated motor controller through a rotary transformer wire harness, and the integrated motor controller monitors the operation state of the upper motor in real time according to received feedback information and reports fault information of the upper motor. In this embodiment, the facial make-up motor is connected with integrated motor controller's the plug-in components that become soon through becoming soon the pencil, turns to and adopts water joint or high-voltage connector to connect between motor controller and the air compressor machine motor controller and the three-phase high-voltage line of facial make-up motor soon.

The control system also comprises an upper controller, the upper controller is connected with the low-voltage control plug-in unit of the integrated motor controller through a low-voltage wire harness, and a control signal sent to the integrated motor controller by the upper controller CAN be transmitted in a CAN communication or hard wire enabling mode. The upper-mounted controller CAN receive an upper-mounted operation instruction sent by an operator through a button or a touch screen, the operation instruction CAN be a hard-wire work enabling instruction or a CAN communication work rotating speed instruction, the upper-mounted controller sends a control signal to the integrated motor controller after processing, and the integrated motor controller controls the upper-mounted motor to operate or shut down by combining the working state and the fault condition of the whole vehicle after receiving the control signal sent by the upper-mounted controller, and monitors and transmits the operation and fault information of the upper-mounted motor in real time through CAN communication.
