Embodiment Construction

[0038] In the normal operation of the encoder, in addition to the sensing device reading the rotation position data of the code disc, the decoding program on the MCU chip core needs to decode the encoded signal read and output by the sensing device, and then output accurate absolute position information. In fact, according to the difference of the measurement object of the encoder, the working program executed on the MCU chip is also more or less different.

[0039] When the working program on the MCU chip needs to be updated due to bugs or the update of the measured equipment, etc., the encoder needs to be disassembled, and the outer shell of the encoder needs to be disassembled, and the special update tool It is connected with the updating pin of the MCU chip in the encoder, and the working program in the MCU chip is updated through the new working program stored in the updating tool.

[0040] For the above-mentioned process of updating the working program of the MCU chip of...

Abstract

The invention discloses a program updating method of an encoder. The program updating method comprises the following steps: receiving a program updating instruction sent by an upper computer; erasing the original working program, and downloading a new working program through a communication link connected between the upper computer and the encoder; and writing the new working program into the storage space after the original working program is erased. According to the application, the new working program is downloaded through the existing communication link between the upper computer and the encoder, so that the working program of the MCU chip in the encoder is updated, the program updating difficulty of the encoder is reduced to a certain extent, the working efficiency of program updating of the encoder is improved to a certain extent, and the updating cost is reduced. The invention further provides a program updating device and system of the encoder, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of encoders, in particular to an encoder program update method, device and system. Background technique [0002] As a measuring device, the encoder is often installed as an embedded component at the rear end of the shaft similar to the servo motor, and requires an external casing for sealing and shielding. However, for encoders installed in equipment such as servo motors, the working programs that have been burned before leaving the factory will inevitably have various defects during the testing stage or even the use stage. It is necessary to involve engineers to produce a new version of the program after solving the bug, so as to update the original working program. Contents of the invention [0003] The object of the present invention is to provide a program updating method, device and system of an encoder, which can reduce the difficulty and cost of updating the program of the encoder to a certain exte...
