Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings, but the invention can be embodied in many different forms and is not limited to the embodiments described in this specification. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right" and similar expressions are used ...

Abstract

The invention discloses a new energy automobile motor health detection control system comprising a main chip module, an electromagnetic compatibility, a pressure bridge circuit driving circuit, a power supply, a pressure signal conditioning circuit, an RS422 output circuit, a temperature signal conditioning circuit, a vibration signal conversion circuit and a rotating speed signal conditioning circuit; the system is used for monitoring rotating machinery conditions, monitoring pressure, temperature, vibration and rotating speed signals at the same time and outputting the signals in an RS422 mode after being processed, the vibration signals and the temperature signals are used as main signals, single-shaft vibration is achieved, the units are arranged on the top of a motor, the vibration signals of motor rotation are measured in real time, and when the transverse displacement speed of motor vibration is larger than a fixed speed threshold value or the internal temperature, collected by four temperature sensors, of the motor is higher than a set threshold value, a main chip sends an alarm instruction; and the system has the advantages of high precision, strong anti-interference capability, good applicability and wide application prospect.

Description

technical field [0001] The invention relates to the field of new energy vehicle motor safety, in particular to a new energy vehicle motor health detection and control system. Background technique [0002] The new energy vehicle motor drive system is the core part of the electric vehicle, which converts the DC bus voltage output by the battery into alternating current in the pure electric vehicle, and uses the alternating current to drive the motor to run. The driving force of the vehicle all comes from the on-board motor. Under different working conditions, the driving force required by the car is different. The motor can only output torque. The drive wheels propel the vehicle forward in the form of torque. Because the car often undergoes acceleration, deceleration, emergency stop and other situations, the requirements on the motor are very high, but it cannot guarantee that the motor will not be in any condition. Contents of the invention [0003] From the perspective o...
