Description

Automatic door controlling system comprising dual controllers

The present invention relates to an automatic door control system including a dual control unit applicable to an electric vehicle.

In general, an electric vehicle is composed of a plurality of vehicles. In this case, one vehicle includes a plurality of door systems, and one door system may include a door control device, a motor, an engine unit for transmitting rotational force of the motor, and a door panel. In addition, the door system may further include a variety of sensors and actuators (actuator) and the like for implementing the essential functions required for the door system and a specialized driving mechanism by the designer.

The door control device includes a control algorithm that can organically operate each component included in the door system. After receiving the open / close command from the host system (TCMS / ATO) or the driver's command, the door control device automatically controls the opening and closing of the door by performing an internal signal processing process and a calculation process for driving the motor. . Each door control device is connected to a network including a communication line, and the doors on one side are opened and closed in a batch.

When all doors are normally closed, a series of closed loops (green loops) are formed, which are sent to the host system (TCMS / ATO) to generate the next open condition signals, the low-speed signal and the open signal. To do it.

When manual opening is attempted by emergency steering wheel operation during vehicle movement, the door control device controls manual opening only when a low speed signal is generated in order to prevent a safety accident. In addition, the door control device may detect an object caught between the door panels and take an appropriate action. When the vehicle is moving, the door control device controls the door in the closing direction.

The door control unit is equipped with a "Circuit Operation Self Test", "Storage of major error states in the CPU", and "to protect itself against errors that may occur during data processing or control processing. Software monitoring and reprocessing functions, ”and the like, and defect detection logic that enables recovery from temporary operation errors. Therefore, it is possible to clearly diagnose the failure of the door system, and it is easy to repair and maintain during the operation of the system.

The failure type of the door system can be divided into a failure of the door control device itself and a failure of an external element (mechanical part) of the door control device constituting the door system. In the event that a serious fault condition that no longer controls the door system makes it difficult to recover the defect, the door control device displays a failure condition and waits for the bypass step to be performed because the door system cannot be guaranteed to operate normally.

Bypass of the door, the failure determination process through the host system (TCMS / ATO) is terminated, the locking of the door is automatically locked by the locking device, the location information of the failed door is displayed on the monitor After the location information of the failure door is recognized by the crew, the crew manually operates the bypass switch, and a delay occurs during this process. During these delays, delays in train operation or safety issues may occur.

In addition, in the door system, a situation in which the door control device loses a control function in a state in which the door is not fully opened or closed may cause the automatic control in the closing direction to be impossible.

The control unit and peripheral circuits included in the general door control device are designed in a single structure, and a command processing system for performing a required function is also designed in one path. At this time, if the door is not controlled smoothly due to an internal operation error, a temporary failure may occur. In this case, the self-recovery method may be recovered through a self-recovery technique through fault detection or a power initialization method through system monitoring.

The control unit included in the general door control device has an advantage of simplicity of implementation. However, in the event of a defect in the door control device, the basis for determining whether there is a failure is insufficient. There is a disadvantage that the probability of entering increases. Therefore, the door control device has a higher number of times of transition to a failure state, thereby increasing the rate of performing the bypass step, and thus it is difficult to satisfy the quantitative target value for availability.

It is an object of the present invention to provide a door control device with improved safety and availability by applying a dual system structure.

The control unit may further include a power management unit configured to receive power supplied from the power supply unit and manage power applied to the main control unit and the auxiliary control unit, wherein the power management unit is one of the main control unit and the auxiliary control unit. When at least one of the defects occurs, the supply of power to the controller in which the defect occurs may be blocked, and the power manager may be a vital power cut-off circuit.

The defect detecting unit may include a primary defect detecting unit configured to detect a defect by real-time monitoring an operating state of a control unit including a defect detecting unit of the main control unit or the auxiliary control unit; And a secondary defect detection unit configured to detect a defect by comparing synchronization information of the main control unit and the auxiliary control unit or operation result values of the main control unit and the sub control unit, wherein the secondary defect detection unit includes the main defect unit. One control unit and one auxiliary control unit may be included in common.

Here, the communication unit may use the RS-485 communication method and CAN communication, and may use the USB communication method as an external interface for checking and monitoring the device of the door control device.

The driving unit may include a control circuit and a feedback loop circuit for driving the motor, and the control circuit controls the opening / closing speed of the door by adjusting an amount of current flowing through the motor through a pulse width modulation (PWM) method. In addition, the feedback loop circuit can ensure the fully opened and closed state of the door by using a PID (proportional integral differential) control scheme.

The power supply unit may receive noise from a high frequency and a low frequency component by receiving a DC power supply, and the auxiliary control unit controls opening and closing of the door and controlling opening and closing of the door when a defect occurs in the main control unit. And a bypass function for controlling the door control device to be excluded from the door control system.

The train computer 150 includes a function of tying a passage, a cable, and the like through which wiring used in the automatic door control system 100 passes. The vehicle monitoring device 110 is located at the top of the automatic door control system 100 according to the present embodiment, and the train computer 150 is included in the middle, and each door control device 120 is provided through the train computer 150. Communicate with the vehicle monitoring device 110. Thus, the automatic door control system 100 according to the present embodiment has a hierarchical structure because there is a limitation in the wiring space structure in the train that can perform wiring.

In addition, when the automatic door control system 100 uses RS-485 or CAN communication, the train computer 150 serves as a component of the vehicle network and includes a bridge function for packet communication.

The individual door control unit 120 may open and close the door 130 of each vehicle included in the train, and access the same through a monitoring program for managing the history of the door 130. The door control device 120 for controlling the door 130 should perform a normal opening operation when the train stops and a normal closing operation after handling the passenger, and always open the door 130 in the closing direction when the train is in operation. The door 130 is controlled to maintain the state of.

According to the present exemplary embodiment, the door control apparatus 120 may include reliable hardware to reduce a failure rate of itself, thereby minimizing a train operation delay due to an operation problem of the door system. In addition, the door control device 120 according to the present embodiment has a dual structure in which the control unit is separated in hardware so as to compensate for the stability problem of the existing door control device configured as a single system. That is, the control unit includes a main control unit and an auxiliary control unit, and the performance of the dual system logic in which each control unit including the peripheral circuit is used may be implemented through a vital power cut-off circuit. When a problem occurs in the main control unit, the auxiliary control unit processes a part of the task performed by the main control unit, and the seasonal body process is performed to move the control right. Hereinafter, the door control device 120 will be described in more detail with reference to FIG. 2.

The vehicle monitoring apparatus 110 may be included in an automatic train operation (ATO), where the automatic train driving apparatus (ATO) sets the driving conditions of the train on the ground (rail) to a vehicle (power vehicle). Transmission means a device that can automatically perform the departure, braking, speed increase, opening and closing of the door 130, etc. without the operator's operation.

The vehicle monitoring apparatus 110 may exchange an opening / closing command signal, a low speed signal, and a green loop signal of the door 130 through a communication line with each door control device 120. The signal generated from the vehicle monitoring device 110 is transmitted to the door control device 120 through a communication line, thereby enabling the door 130 to be opened and closed. In addition, external condition signals for opening / closing the door 130 may also be transmitted through a communication line.

The communication line is able to perform the role of a communication line by transmitting and receiving an electric signal using a voltage level of DC 100V in order to minimize computer intervention in inputting and outputting a door control command. It is constructed using an electrical signal control element such as a relay. Hereinafter, it will be clear that the human line is used in the same meaning in the present specification.

When all the doors included in the automatic door control system 100 according to the present embodiment are normally closed, the automatic door control system 100 is configured with a closed circuit connected in series to generate an interlock signal. The generated interlock signal is transmitted to the vehicle monitoring apparatus 110 through a communication line to complete reception of a green loop signal, which is a vehicle starting condition signal. That is, when the door 130 is completely closed or a failure occurs in the door system, the green loop signal may be transmitted to the vehicle monitoring device only when the interlock signal is generated by the bypass function, and the vehicle monitoring device receives the green loop signal. The vehicle can be started later.

The interlock signal is a signal generated from each door 130 and refers to the same signal as the bypass signal, and fails when any one of the doors 130 included in the automatic door control system 100 fails to generate a signal. The signal is transmitted from the door control device 120 to the vehicle monitoring device 110 to be recognized. Hereinafter, in the present specification, the interlock signal is used as the above meaning.

Interlock is a term used for a signal system in which a signal generated in the Nth system affects a signal generated in a system after the N + 1th system when there are a plurality of systems. Each door control device 120 included in the present embodiment is configured with a 100 V signal line. At this time, when the closing operation of each individual door 130 is completed, the physical connection to the 100V signal line, but when the door control device 120 fails in the physical connection due to various obstacles, the closed circuit configuration fails to the vehicle The monitoring device 110 recognizes that an abnormality occurs in the closing operation of the door 130, it is impossible to start the vehicle until the obstacle is removed.

The green loop signal is transmitted to the individual door 130 when the interlock signal is intact and the signal is output according to the state of the door system, and the signal is returned to the vehicle monitoring device. In addition, the green loop signal and the open condition signal are used as the above meanings.

As shown in FIG. 1, one door control device 120 may be connected to one door 130, and the door 130 may be automatically opened and closed by a control command of the door control device 120.

The portable test unit (PTU) 140 performs inspection and monitoring of the door control device 120 and may be connected to the door control device 120 using a USB communication method.

Hereinafter, referring to FIG. 2, a configuration of modules of a door control apparatus according to an exemplary embodiment will be described. 2 is a system block diagram of a door control apparatus according to an embodiment of the present invention.

The door control device 120 according to an embodiment of the present invention includes a control unit 121 including a main control unit 121-1 and an auxiliary control unit 121-2, a communication unit 122, a driving unit 123, and a power supply unit. 124 and the communication line input / output unit 125 may be included.

First, the controller 121 may include a main controller 121-1 and an auxiliary controller 121-2. The main controller 121-1 controls opening and closing of the door. The auxiliary control unit 121-2 controls opening and closing of the door when a defect occurs in the main control unit 121-1. As such, when a defect occurs in the main controller 121-1, the auxiliary controller 121-2 may process a part of a task performed by the main controller 121-1 so that the main controller 121-1 is processed. It is possible to prepare for a malfunction.

The main control unit 121-1 performs the overall control function of the door opening and closing and the door control unit 120 when the main control unit 121-1 operates normally, and the auxiliary control unit 121-2 performs the main control unit 121-. In the normal operation state of 1), the door opening / closing operation is not performed, but the state is kept in synchronization with the main control unit 121-1. Thus, the controller includes the main controller 121-1 and its peripheral circuits, and a "machine" including the auxiliary controller 121-2 and its peripheral circuits.

As described above, the auxiliary controller 121-2 maintains the state synchronized with the main controller 121-1 as follows. The signal generated in connection with the opening and closing of the door from the vehicle monitoring apparatus 110 can be simultaneously received by the main control unit 121-1 and the auxiliary control unit 121-2. Therefore, since one control unit processes the command related to opening and closing the door to be divided into two control units, the auxiliary control unit 121-2 controls the main control unit 121 in the case where a defect occurs in the main control unit 121-1. This is because accurate synchronization of the current state of the door must be achieved in order to replace the task of -1). At this time, the information that can determine the current state of the door may include the location information of the door and the information received from the drive unit 123.

As such, the main control unit 121-1 processes all input signals input through the communication line input / output unit 125, including opening and closing of the door, and the auxiliary control unit 121-2 has a minimum function related to opening and closing the door. Only carry. That is, the auxiliary control unit 121-2 maintains the state in synchronization with the main control unit 121-1 to monitor whether or not a defect occurs in the main control unit 121-1. When a defect occurs in the main controller 121-1 and the control right is transferred to the auxiliary controller 121-2, the auxiliary controller 121-2 of the door control apparatus 120 is output from the vehicle monitoring apparatus 110. Respond to an open or close command. However, when a defect occurs in the main control unit 121-1, and the driving unit 123 is unable to operate, the auxiliary control unit (2) after the control right related to the opening and closing of the door 130 is moved to the auxiliary control unit 121-2. By 121-2) automatically bypasses the operation of the door 130 is stopped.

The main controller 121-1 and the auxiliary controller 121-2 may each include a defect detector for detecting whether a defect has occurred. In this case, the defect detection unit is included in each of the main control unit 121-1 and the auxiliary control unit 121-2, and includes a primary defect detection unit for monitoring a real time operation state of the included control unit and detecting a defect, and a main control unit ( 121-1) and a secondary detection unit for detecting a defect by comparing the synchronization information of the auxiliary control unit 121-2 or the calculation result values of the main control unit 121-1 and the auxiliary control unit 121-2. Can be.

As described above, the primary defect detection unit may be included in each of the main control unit 121-1 and the auxiliary control unit 121-2, and may detect the primary error by itself, including the self checking unit. To this end, a self-test unit having a delay circuit and a comparator may be included in the primary defect unit. The primary defect detection unit performs hardware real-time monitoring through the self-test unit, and detects the primary error by real-time detection of an operation state of the controller including the primary defect detection unit based on the hardware defect.

The secondary defect detection unit 121-3 may be included in the main control unit 121-1 and the auxiliary control unit 121-2, respectively, but as shown in FIG. 2, the main control unit 121-1 and the auxiliary control unit are shown. 121-2 may have one secondary defect detection unit 121-3 in common. As described above, the main control unit 121-1 and the auxiliary control unit 121-2 commonly have one secondary defect detection unit 121-3 in common. There is an advantage that the processing speed is faster than in the case 2) each includes one secondary defect.

As described above, the primary defect detection unit detects an operation state of the main control unit 12101 or the auxiliary control unit 121-2 including the primary defect unit to detect the primary error. On the other hand, when the secondary defect detection unit 121-3 is included in the relative control unit-main control unit 121-1, and when included in the auxiliary control unit 121-2 and the auxiliary control unit 121-2, the main control unit 121- By comparing the synchronization information or the calculation result values of 1)-, the secondary defect can be detected.

The secondary defect detection unit 121-3 is the secondary control unit 121-2 in the case of the relative control unit, that is, the main control unit 121-1, and the main control unit in the case of the auxiliary control unit 121-2, for the secondary error detection. And error detection logic for detecting defects by exchanging and comparing the synchronization information or the operation result value with each other in real time. The secondary defect detector 121-3 may exchange clock information for comparing synchronization information. As such, in order to store and compare the clock information or the calculation result value during the control period, an external memory may be included in the secondary defect detection unit 121-3. In the normal operation state of the door control device 120, the main controller ( 121-1) and the auxiliary control unit 121-2 perform the same calculation process in connection with opening and closing the door, and only the calculation result of the main control unit 121-1 is reflected in the door opening and closing operation. In this way, each control unit generates a specific operation result for the control of the door, the secondary defect detection unit 121-3 is a corresponding operation result value (for example, the current position information of the door, the current state of each actuator, upper level) Information received from the system and information generated from the sub-system (drive unit), etc.) may be stored and defects may be detected by comparing the values.

The defect detection unit includes the primary defect detection unit and the secondary defect detection unit 121-3 so that each control unit, that is, the main control unit 121-1 and the auxiliary control unit 121-2 has a built-in self-test circuit to detect internal defects. And then compare the data values performed by the main control unit 121-1 and the sub control unit 121-2 to reconfirm that a defect has occurred in each control unit. This process increases the accuracy of defect detection.

When the door control apparatus 120 operates normally, the main controller 121-1 and the auxiliary controller 121-2 receive the same information and process the same. Therefore, the synchronization information or the calculation result value should be the same. do. To this end, the main controller 121-1 and the sub controller 121-2 share the same system clock and must perform a synchronization process. For example, the main control unit 121-1 and the sub control unit 121-2 may output information generated from the upper system, condition signals, open / close signals, signals generated from the driving unit, encoder pulse information, hall sensor information, and the like. The current position of the motor included in the driving unit may be calculated based on the inputs, and the driving unit may transmit analog (motor current value) data to each control unit so that each control unit may perform AD conversion or DA conversion. As described above, the main control unit 121-1 performs a function required for the door control device 120 alone, and the auxiliary control unit 121-2 performs the secondary control unit. Since it serves to ensure normal operation, the range of functions that can be performed by the main control unit 121-1 and the auxiliary control unit 121-2 is clearly distinguished.

The auxiliary control unit 121-2 performs a control operation for opening and closing the door when a defect occurs in the main control unit 121-1 and the door opening and closing operation is not performed smoothly. For this process, the control unit 121 may include a power management unit 121-4.

The power management unit 121-4 receives power supplied from the power supply unit 124 supplying power to the door control device 120, and is applied to the main control unit 121-1 and the auxiliary control unit 121-2. Manage it. When a defect occurs in at least one of the main control unit 121-1 and the auxiliary control unit 121-2, the power management unit 121-4 blocks the supply of power to the control unit where the defect is generated.

That is, when a defect occurs in the main control unit 121-1, since the power supply unit 121-4 cuts off the power supplied to the main control unit 121-1, the main control unit 121-1 does not operate. The auxiliary control unit 121-2, which fails to perform the defect, does not perform the door opening and closing operation performed by the main control unit 121-1. In this case, the power manager 121-4 may be formed of a vital power cut-off circuit. The vital power cutoff circuit is a circuit used in a dual system, and refers to a circuit for automatically controlling power applied to the main controller 121-1. Hereinafter, in the present specification, the vital power cut-off circuit is used as the above meaning.

The power management unit 121-4 receives power from the power supply unit 124 and supplies stabilized DC power to each of the control units 121-1 and 121-2, and controls each of the control units 121-1 and 121-2. If both are in a normal state, power is simultaneously supplied to both of the controllers 121-1 and 121-2 to perform the functions of the respective controllers 121-1 and 121-2. When a defect occurs in at least one of the controller 121-1 and the auxiliary controller 121-2, power is supplied to the controller in which the defect is generated.

The defect detected by the defect detection unit may be classified as a defect in case of failure or failure in case of failure, depending on whether the driving unit 123 can be driven. When a minor defect occurs in the main controller 121-1, the auxiliary controller 121-2 performs the opening and closing operation of the door. In addition, when a major defect occurs in the main control unit 121-1, the vehicle monitoring apparatus 110 excludes an entrance door to which the door control device 120 including the main control unit 121-1 in which the major defect occurs has been opened or closed. Bypass function can be performed automatically

Bypass function, as described above, when a defect occurs in the main control unit 121-1, and it is difficult to open and close the door normally, except for the door that the vehicle monitoring device 110 automatically failed. Normally controlling other doors.

That is, the vehicle monitoring device 110 performs the bypass function by reconfiguring a closed circuit that is disconnected due to the defective door control device 120 and the door 130 connected thereto, thereby rest of the door control device 120. ) And the door 130 connected thereto may perform a normal operation.

This is because the interlock signal is not generated until the closed circuit is reconfigured, and the vehicle monitoring apparatus 110 may recognize the signal and determine the departure of the vehicle.

The communication unit 122 performs communication between the control unit 121 and the vehicle monitoring apparatus 110, and may use an RS-485 communication method and a CAN communication method. In addition, the communication unit 122 may perform a device inspection and monitoring function of the door control device 120, and for this purpose, a USB communication method may be used.

The driving unit 123 performs the opening / closing operation of the door 130 according to the command of the control unit 121. According to the present embodiment, the driver 123 may include a control circuit and a feedback loop circuit for driving a motor. The control circuit controls the opening / closing speed of the door 130 by adjusting the amount of current flowing through the motor through a PWM (Pulse Width Modulation) method, and the feedback loop circuit uses the PID (proportional integral differential) control method. To ensure complete open and close condition.

As described above, the power supply unit 124 supplies power to the door control device 120. According to the present embodiment, the power supply unit 124 may receive DC power to remove noise of high and low frequency components.

As described above, in the automatic door control system according to the present embodiment, the control unit includes a main control unit and an auxiliary control unit, so that when a defect occurs in the main control unit, the auxiliary control unit can perform the door opening and closing operation, and the driving unit In the case where a defect occurs while driving is impossible, by bypassing the door control device including a control unit in which the defect is generated, it is possible to prevent a train delay and a safety accident due to a door control device defect.

In addition, through the primary defect detection unit and the secondary defect detection unit including a magnetic inspection unit to ensure the reliability of the device, it is possible to accurately diagnose and recover the defect of the door control device 120.
