JPH0920469A - Control device for elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide commonness of a part by constituting a plurality of electronic circuits of different function in a single electronic part, and giving a function selecting signal from the outside, so that a plurality of the functions can be used, in the electronic circuit mounted on a control panel of an elevator. SOLUTION: A printed board 1 is divided into two parts, main microcomputer part 2 and auxiliary microcomputer part 3, to respectively constitute the main microcomputer part 2 by circuits A to C, E part 4a to 4c and by four blocks 4e, and the auxiliary microcomputer part 3 by circuits A, D and three blocks of F parts, 4a, 4d, 4f. In the case of giving an H signal to a function selecting signal 11, each circuit 4b, 4c is operated to perform inputting/outputting a signal relating to each circuit 4b, 4c (circuit 4d is placed in an inoperative condition). In the case of giving an L signal to the function selecting signal 11, the circuit 4d is operated to perform inputting/outputting a signal relating to the circuit 4d (circuits 4b, 4c are placed in an inoperative condition).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic circuit formed on a printed circuit board, and more particularly, to an elevator in which a plurality of electronic circuits having different functions are formed in one electronic part to make the parts common and small in space. Regarding the control device.

[0002]

2. Description of the Related Art In a conventional electronic circuit, since each function is individually configured, the number of parts mounted on a printed board increases. Along with this, it was necessary to secure a large space for mounting components (Japanese Patent Laid-Open No. 57-81076).

[0003]

In the above-mentioned conventional technique, there is a problem that a large mounting space for components must be secured because the number of mounting components increases.

An object of the present invention is to reduce the number of parts and the space for mounting parts.

Another object of the present invention is to standardize parts to improve the mass production effect.

[0006]

The above-mentioned object can be achieved by constructing a plurality of electronic circuits having different functions in one electronic component and applying a function selection signal from the outside to select the function.

[0007]

Since electronic circuits having different functions are formed in one electronic component, the number of mounted components can be reduced and the component mounting space can be reduced. Moreover, since one electronic component can be used for a plurality of functions, the components can be shared.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a circuit configuration of a printed board 1, the inside of which is divided into a main microcomputer section 2 and a slave microcomputer section 3. Further, the main microcomputer unit 2 is composed of a total of four blocks, that is, a circuit A unit 4a, a circuit B unit 4b, a circuit C unit 4c, and a circuit E unit 4e.
The circuit D section 4d and the circuit F section 4f are composed of a total of three blocks.

The circuit A section 4a, the circuit B section 4b, the circuit C section 4c, and the circuit D section 4d are formed inside the common electronic component 10. Here, the rotation E section 4e and the circuit F section 4f are circuits that cannot be configured without the common electronic component 10.

FIG. 2 shows a circuit configuration inside the common electronic component 10. The function of the common electronic component 10 can be switched by the function selection signal 11.

When the "H" level is given to the function selection signal 11, the circuit B section 4b and the circuit C section 4c operate and the circuit B section
Alternatively, a signal is input / output to / from the circuit B unit 4b via the signal input / output bus line 12 of the circuit D, and a signal is input / output to / from the circuit C unit 4c via the signal input / output bus line 12c of the circuit C. At this time, the circuit D section 4d does not operate.

When the "L" level is given to the function selection signal, the circuit D section 4d operates to input / output a signal to / from the circuit D section 4d via the signal input / output bus line 12 of the circuit B or the circuit D. . At this time, the circuit B section 4b and the circuit C section 4c
Does not work.

The circuit A section 4a performs signal input / output with the circuit A section 4a via the input / output bus line 12a of the circuit A without depending on the function selection signal 11.

Therefore, the circuit formed on the printed board has two common electronic parts 10, the circuit E section 4e and the circuit F section 4
It can be realized by f.

According to this embodiment, it is possible to reduce the size of the printed board and use common parts.

[0017]

According to the present invention, since electronic circuits having different functions are formed in one electronic component, the number of mounted components can be reduced and the component mounting space can be reduced.

Further, since one electronic component is used for a plurality of functions, the components can be made common and the mass production effect can be improved.
