Abstract: This application provides a motor cooling system of an electric vehicle. In the cooling system, a coil cooling oil passage includes a first oil outlet that is at an end portion of a stator core. A core cooling oil passage and the coil cooling oil passage are sequentially connected. In this case, cooling oil first enters the core cooling oil passage, and then enters the coil cooling oil passage. The core cooling oil passage extends in a circumferential direction of the stator core. The coil cooling oil passage extends in an axial direction of the stator core. A power apparatus drives the cooling oil to enter the core cooling oil passage from an oil inlet, flow through the core cooling oil passage, and enters the coil cooling oil passage from an oil through port. The cooling oil flows back to an oil return groove from the first oil outlet.

Abstract: Embodiments of the present invention provide a data processing method, a coordinator, and a node device. The coordinator receives a data frame sent by the node device, where the data frame includes service data; the coordinator determines whether the service data is within a set data confidence interval; and if the coordinator determines that the service data is beyond the data confidence interval, the coordinator sends a questioned-data frame to the node device, where the questioned-data frame carries the service data, so that the node device confirms correctness of the service data.

Abstract translation: 本发明的实施例提供了一种数据处理方法，协调器和节点装置。 协调器接收节点设备发送的数据帧，其中数据帧包括业务数据; 协调器确定服务数据是否在设置的数据置信区间内; 并且如果所述协调器确定所述服务数据超出所述数据置信区间，则所述协调器向所述节点设备发送询问数据帧，所述受询数据帧携带所述服务数据，以使得所述节点设备确认所述服务的正确性 数据。

Abstract: Embodiments of the present invention disclose a node scheduling method, where the method includes: configuring, for a node, a working period matched with a performance indicator of the node, where duration of the working period is an integer multiple of duration of a super frame, and the super frame is a super frame corresponding to a beacon frame in a network in which the node is located; and sending, to the node, an updated beacon frame that includes information about the working period, so that the node acquires the information about the working period from the updated beacon frame, receives a working beacon frame, establishes a super frame corresponding to the working beacon frame until the working period ends, and then repeats the receiving a working beacon frame and establishing a super frame corresponding to the working beacon frame until the updated beacon frame is received again.
