Description

Programming device for camshaft revolution speed sensor

Technical Field

The utility model relates to a speed sensor production test field, more specifically say, relate to a camshaft speed sensor programmer.

Background

In the aspect of the application of the sensor in the field of industrial control, a rotation speed sensor is a sensor that converts the rotation speed of a rotating object into electric quantity for output. The rotation speed sensor belongs to an indirect measuring device and can be manufactured by a mechanical method, an electrical method, a magnetic method, an optical method and a mixed method. The rotation speed sensor can be divided into an analog type and a digital type according to different signal forms. The sensor chips produced by the company of English-flying, the leading sensor company in the world, are used in a large number of applications, and the TLE4984C chip utilizing the Hall effect principle is a typical representative. The TLE4984C chip is internally integrated with a PROM memory, and the sensor can be shipped after injection molding production and binding by calibration programming.

The chip TLE4984C of Yingfei integrates a PROM memory, and the sensor chip and the magnet are bound by injection molding and then need to be calibrated and programmed for delivery. However, for a number of reasons, the british flying company does not offer a ready-made programmer product, which can only be made by the user himself, and for this reason we propose a camshaft revolution speed sensor programmer.

The working principle is as follows: data input into the chip is input through a Vs pin of the chip, the low level is 5V, the high level is 8V, a digital '1' is represented by a combination of 2/3 high level and 1/3 low level, a digital '0' is represented by a combination of 1/3 high level and 2/3 low level, and the level used by a peacetime singlechip is completely different, so that communication protocol conversion is needed. The protocol conversion circuit in the programmer completes the part of work; after the communication data is read and written, because a PROM memory is used inside the TLE4984C chip, a voltage greater than 18V needs to be provided on the Q pin as a fuse blowing voltage, so that the programming work is finally completed. The high voltage programming module in the programmer accomplishes this. After programming is completed, the chip is verified once again, and the verification result is displayed on the liquid crystal display panel 4 of the programmer.
