Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 As shown, the E-ACT position control and speed measurement system and method based on the SENT protocol includes: an acquisition operation unit 1, an external power supply unit 2, a pulse commutation unit 3, a host computer control display unit 4, and an electric ACT sensor 5. The acquisition operation unit 1 has an input end connected to the SENT protocol data signal of the electric ACT sensor 5, and an output end connected to the pulse commutation unit 3 and the host computer control display unit 4. The external power supply unit 2 is connected to the pulse commutation unit 3 . The pulse commutation unit 3 has an input end connected to the acquisition operation unit 1 and an external power supply unit 2 , and an output end connected to the electric ACT sensor 5 . The upper computer controls the display unit 4 and is...

Abstract

The invention relates to an E-ACT fixed-point position control and speed measurement system and method based on the SENT protocol. The system includes: acquisition operation unit, external power supply unit, pulse commutation unit, host computer control display unit, electric ACT sensor. The method includes: when the positioning control is started, the acquisition operation unit receives the positioning control command from the upper computer control display unit, and adjusts the PWM pulse control signal to the pulse reversing unit so as to control the electric ACT sensor to move to the specified position. When the speed test is started, the acquisition operation unit collects and analyzes the position information of the electric ACT sensor in real time, and calculates its average speed. The invention not only has the function of analyzing the SENT protocol, but also can measure and calculate the motion speed of the ACT and precisely control the position of the ACT at the same time, the control response speed is fast, and the control of any position can be completed within 1 second. And the time base for calculating the speed is as high as ns level, with high precision.

Description

technical field [0001] The invention relates to the field of analysis and product application of the SENT protocol, specifically an E-ACT position control and speed measurement system and method based on the SENT protocol. Background technique [0002] At present, sensors output by the SENT (Single Edge Nibble Transmission, Chinese name is unilateral nibble transmission protocol) protocol have been used on many parts of the car. Many domestic automobile manufacturers also use this kind of sensor, but most of them are imported, and there are few collection and processing units specially for this SENT protocol sensor in China. In response to this situation, after successfully inventing the SENT protocol frame data analysis converter data sampling analysis system, our company further developed a new precise position control function and speed measurement function, and formed this product. Contents of the invention [0003] Because other similar products cannot be found in Ch...
