In addition, an individual control panel for opening and closing the screen door by receiving a signal generated from the comprehensive control panel is installed.

A conventional individual control panel for controlling each screen door in such a platform is configured in a form in which control functions such as a motor for opening and closing a door and a front panel are performed by a control board incorporating one or two control functions. As a result, it becomes a noise generation factor due to interference or it is difficult to identify the cause when a failure occurs, and the maintenance efficiency is very low, such as the need to replace the entire individual control panel equipment due to a simple cause of failure.

In addition, existing individual control panels have several thick communication cables for connecting external interfaces and transmitting internal control signals, which cause frequent breakdowns and difficult maintenance due to complicated internal wiring. In particular, in the case of an individual control panel in which the power unit is embedded in the main board, there is a problem in that the expensive main board needs to be replaced even in the case of simple component damage of the power unit.

In addition, existing individual control panels using low-spec MCUs have a relatively slow operation speed, which causes a delay in the operation of the platform safety door due to the delay in control, and it is difficult to check the presence or absence of abnormalities in the control device in real time, which makes it difficult to quickly deal with failures. contains

First, referring to the configuration of the motor control module 100 according to FIG. 2, the microcontroller 101 communicates through the DCU connection unit 102 and receives an open/close control command through communication, and the microcontroller 101 operates the motor through the motor driver module 104. generated as a driving signal.

The driving speed of the motor is input through the motor speed measurement module 105, and the driving current of the motor is measured by the current measurement module 106 to determine the state and normal state of the motor. Power for driving the MDU 100 is delivered through the PSU connection unit 103 .

And, referring to FIG. 3 showing the configuration of the front panel control module 200 according to an example, the microcontroller 201 communicates through the DCU connection unit 202, and among the received data, time information is the FND module 206 and the LED module 207, and the voice information is output to the audio module 208 and the buzzer module 209.

In addition, a value manipulated by a user may be input through the ID switch module 204 and the button module 205 . Power for driving the FDU 200 is delivered through the PSU connection unit 203 .

And, referring to FIG. 4 showing the configuration of the main control module 300 according to an example, the FDU connection unit 303 communicates with the FDU 200, the MDU connection unit 304 communicates with the MDU 100, and the external Checking the status of peripheral devices through the controller connection unit 302, transmitting signals to the main control panel (not shown) and the comprehensive control panel (not shown), and controlling the opening and closing of the platform safety door (ie, controlling the MDU 100) function. Likewise, power for driving the DCU 300 is delivered through the PSU connection unit 305 .

Here, according to an example, each of the microcontrollers 101, 201, and 301 shown in FIGS. 2 to 4 applies a high-performance microcontroller having a 32-bit multi-core to increase the processing speed so that the stability of the control function can be secured. .

And, referring to the configuration of the multi-voltage power supply module 400 according to FIG. 5, it is a module that supplies driving power to the MDU 100, FDU 200, and DCU 300, and the MDU through the power connector 404. +12V (401), +24V (402), +40V (403) are supplied to (100), +24V (402) is supplied to FDU (200), and +24V (402) is supplied to DCU (300). supply

Here, according to another example, the components of reference numerals 401 to 403 of the multi-voltage power supply module 400 may be implemented as physically independent devices, whereby even if a failure occurs in one of the components, the other components operate normally and corresponding It is possible to cause the control module to be driven.

And, referring to FIG. 6 showing the configuration of the main control module 300 according to another example, the main control module 300 may further include a temporary function unit 306 . The temporary function unit 306 is intended to temporarily substitute a function when a failure occurs in the motor control module 100 or the front panel control module 200.

The microcontroller 301 of the main control module 300 determines whether the motor control module 100 and the front panel control module 200 are out of order. For example, when a control signal is transmitted, a corresponding response signal should be received, but if the response signal is not normally received, it may be determined as a failure. According to an example, when the main control module 300 determines that a failure has occurred in the motor control module 100 or the front panel control module 200, failure information is sent to an external device (eg, the main control panel, etc.) or the front panel. A fault signal may be output by transmitting or using a lamp (not shown) provided therein.

As such, the main control module 300 frequently or periodically checks whether the motor control module 100 and the front panel control module 200 are faulty, and if a fault occurs in any one, the temporary function equipped with the function of the corresponding control module. Unit 306 performs this instead. For example, when a failure occurs in the motor control module 100, the temporary function unit 306 directly controls a driving motor provided in a landing safety door.

Likewise, the temporary function unit 306 can replace the function of the front panel control module 200 when necessary, and for this purpose, the temporary function unit 306 is connected to the front panel and performs direct control.

According to one example, the temporary function unit 306 may replace all functions of the motor control module 100 and the front panel control module 200, but functions necessary for reducing implementation costs (eg, opening of a safety door) , manual conversion function of the front panel control module 200, etc.).

And, referring to FIG. 7 showing the configuration of the front panel control module 200 according to another example, the front panel control module 200 temporarily operates the drive motor of the platform safety door when a failure occurs in the motor control module 100. A temporary motor control unit 210 for controlling may be provided.

According to an example, the temporary motor control unit 210 automatically controls the drive motor so that the platform safety door is in a predetermined specific shape (safety door closed, half-opened, or open).

In addition, according to an example, the temporary function unit of the main control module 300 as shown in FIG. 5 processes in a subordinate order, and the temporary motor control unit 210 of the front panel control module 200 takes precedence over the function of the motor control module 100. It may be a form of temporary replacement.

8 is a configuration diagram of an individual control panel for a landing safety door having an auxiliary control module according to another embodiment of the present invention.

Referring to FIG. 8 , an auxiliary control module 800 may be further included in the individual control panel.

The auxiliary control module 800 functions instead of the motor control module 100, the front panel control module 200, and the main control module 300 when a failure occurs. To this end, the auxiliary control module 800 monitors whether the motor control module 100, the front panel control module 200, and the main control module 300 have a failure, and if there is one that is recognized as a failure, it replaces the corresponding function. carry out As described above, the auxiliary control module 800 may also replace all the functions of the failed control module, but may also be implemented to perform only necessary functions for processing in an emergency situation.

According to the embodiments shown in FIGS. 6 to 8, each control means for each high-performance function is implemented as a physically independent module to increase the convenience of expansion and maintenance, but also if any one control module fails. Even if it occurs, the individual control panel itself is operated normally by temporary function substitution by another device, so that the stability can be further improved.
