Abstract

(57) [Problem] A conventional encoder signal processing method uses a number of receiving IC units corresponding to the number of encoders, so that the shape of the signal processing system is enlarged and the shape of the signal processing system is reduced. It was difficult to do. SOLUTION: The encoder signal processing method according to the present invention is characterized in that each encoder signal (3a to 3n) is converted into one receiving IC unit (1).
This is a configuration in which the signal processing system is downsized as compared with the conventional one by receiving simultaneously by a plurality of receiving functions.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an encoder signal processing method, and more particularly, to a method for receiving an encoder signal from a plurality of encoders by using a single reception IC unit having a plurality of reception functions, and implementing a signal processing apparatus. It relates to a new improvement for miniaturization.

2. Description of the Related Art As a conventional encoder signal processing method of this type, a configuration shown in FIG. 2 has been generally used. That is, what is indicated by reference numeral 1 in FIG. 2 is n known receiving IC units 1A to 1N, and each of the receiving IC units 1A to 1N has an encoder 2
a to 2n are provided. Therefore, the encoders 2a to
Encoder signals 3a to 3n from 2n are individually input to each of the receiving IC units 1A to 1N by wire or wirelessly, and are controlled by a controller (not shown).
1N was selected to control a robot or the like.

[0003]

Since the conventional encoder signal processing method is configured as described above, there are the following problems. That is, since a receiving IC unit is required for each encoder, the encoder signal processing device is complicated, and is increased in size and cost.

[0004] The present invention has been made to solve the above-described problems, and in particular, an embodiment having a plurality of receiving functions.
It is an object of the present invention to provide an encoder signal processing method that receives each encoder signal from a plurality of encoders by using a plurality of receiving IC units and reduces the size of a signal processing device.

[0005]

An encoder signal processing method according to the present invention is an encoder signal processing method in which each encoder signal from a plurality of encoders is received by a receiving IC unit. This is a method of receiving by a plurality of receiving functions in the receiving IC unit.

More specifically, there is a method in which an arbitrary encoder signal among the encoder signals received by the receiving IC unit is extracted by an external command.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the encoder signal processing method according to the present invention will be described below with reference to the drawings. The receiving IC unit 1 shown in FIG. 1 has a plurality of (n) receiving functions (not shown), and each of the encoder signals 3a to 3n of the n encoders 2a to 2n.
3n are input to the respective receiving functions (formed in the form of a plurality of ICs on one substrate) of the receiving IC unit 1 and are received by the respective receiving functions according to a command 4 from the outside. The encoder signals 3a to 3n can be arbitrarily extracted. Therefore, each encoder 2a
To 2n are directly received by the respective receiving functions corresponding to the encoder signals 3a to 3n,
By giving a command 4 from the outside, each receiving function of the receiving IC unit 1 is called, and the corresponding encoder signal 3a
3n are taken out and input to a control device such as a robot to control the entire robot or the like. Therefore, the receiving IC unit 1 has a built-in number of receiving functions corresponding to each conventional receiving IC unit, and has a shape of one receiving IC.
Since only one receiving IC unit 1 can be used, the encoder signals 3a to 3n of the encoders 2a to 2n can be composed of only one receiving IC unit 1.
3n can be received simultaneously by each receiving function. Therefore, each receiving function is formed corresponding to the number of each of the encoder signals 3a to 3n.

[0008]

Since the encoder signal processing method according to the present invention is configured as described above, the following effects can be obtained. That is, a plurality of receiving functions are provided in one receiving IC unit, and only one receiving IC unit can simultaneously receive and process encoder signals of many encoders. The size of the system can be greatly reduced.
