Fig. 3 is a flowchart of a method for controlling a network convergence system according to an exemplary embodiment of the present invention. This method can be applied to the network fusion system as described in any of the above embodiments. The network fusion system includes a passenger information PIS system, an exchange, and a train control and management TCMS system. The TCMS system includes a central control unit CCU and people Machine interface unit HMI; as shown in FIG. 3, the method of this embodiment may include:

Step 301: The CCU controls the operation of the train and monitors the passenger information in the car to obtain the status information and passenger information of the train operation.

In this step, by connecting the CCU to the exchange and the PIS system, the CCU controls the operation of the train and monitors the passenger information in the car. In addition, the CCU can also report the audio station and information in the PIS system. The display is controlled to obtain passenger information in the PIS system, where the passenger information may include: surveillance video information and site information of the camera.

Step 302: The CCU sends the status information and passenger information to the HMI through the switch, so that the HMI displays the status information and passenger information.

In this step, the train operation status information and passenger information obtained by the CCU are sent to the HMI in the TCMS system through the switch, and at the same time, the CCU sends a display command to the HMI through the communication bus, so that the HMI displays the received information.

Optionally, before the CCU controls the operation of the train and monitors the passenger information in the car, it also includes: initializing the line information and the train operation information, and then executing the CCU to control the train operation and monitoring the passenger information in the car .

Specifically, before the CCU controls the operation of the train and monitors the passenger information in the car, the CCU needs to initialize the line information of the train and the operation information of the train, where the operation information of the train may include: the station information of the train (start Station, terminal and current station), the direction of the train (up or down) and the mode of the station (automatic or manual), etc. After the initialization of the train is completed, the CCU is executed to control the operation of the train and monitor the passengers in the car information.

In the actual application process, because CCU is the core component of the TCMS system, it is used to realize the functions of train communication bus management and train operation control. As the communication bus manager, the CCU acts as the train's brain, with functions such as controlling data, fault diagnosis, and system control. The CCU can exchange data with devices of the TCMS system and other sub-devices such as event recorders, HMIs, and remote input and output units via the Ethernet bus to achieve control and data monitoring of the train running status. In order to make the TCMS system operate normally, one CCU can be installed in the driver's cab at both ends of the train, one is the master CCU, one is the slave CCU, and the two CCUs are mutually redundant. DDR and 2GB EDOM, through a 16-bit device ID setting rotary coding switch, you can set the ID number of the main control device, and CCU control software can be developed using OpenPCS Programming 6.System, written in a language that conforms to the IEC61131-3 standard, The software is released as a binary file, and the program is updated through the Ethernet bus interface.

The specific process of the CCU controlling the PIS system can be shown in 4, first, the CCU initializes the train line information and operation information, and detects whether the master-slave CCU is operating normally, and then the master CCU and the slave CCU perform redundant interaction. When the interaction is completed To select the station report mode, the report mode can include automatic and manual, if it is automatic report station control, it will drive FDU, IDU and MDU to display, if it is manual report station control, it will first send the information to DACU and then drive FDU , IDU and MDU for display, or drive LCD for display or playback. Among them, the specific process of the redundant interaction between the master and slave CCUs is shown in FIG. 5, by setting the dial switch IO of the master CCU/slave CCU in the TCMS system to select whether to enable the master CCU or the slave CCU, when the system detects In the case of the master CCU, the master CCU will periodically send interactive data packets to the slave CCU through the Ethernet bus to activate the master CCU. Among them, the period of sending interactive data packets may be 50ms, of course, the period duration can be determined according to the specific situation. The present invention does not make any limitation; when the system detects that the dial switch is in the slave CCU situation, the slave CCU will continuously query the master CCU and slave CCU data packets, and then judge whether the received data packet is correct, exemplary, You can also set a counter that counts the number of data packet errors. If the received data packet is correct, the counter is cleared, and the slave CCU is not activated. Each time an incorrect packet is received, the counter is increased by 1, when it exceeds 20 times. Incorrect data packets, that is, the correct data packets from the master CCU are not received within 1 second, the master CCU is considered offline, and the slave CCU is activated at this time.

In addition, in the actual application process, the HMI screen of the TMS system of the driver's cab is used to monitor the status of the main system equipment such as train traction, braking and network and interactive control functions. One HMI can be placed at each end of the train. The HMI software is used Simplified graphics and text layout, so that the operator can quickly adapt to the operating environment, enter the various display interfaces efficiently and conveniently, and facilitate user settings. For specific HMI, 12.1SVGA touch LCD screen can be used, with a resolution of 1024*768, using Intel ATOM 1.33GHz, Core Z520ST CPU, with 1G memory and 4GB flash memory, HMI software is based on Linux operating system, you can use qt-sdk-linux-x86-opensource-2010.02 QT library for GUI development. The HMI display screen software module can refer to FIG. 6. The HMI display screen can include: real-time display function module, maintenance/test function module, Ethernet communication function module, CCTV video display function module and configuration file module, so as to realize functional interaction. In addition, The HMI display can also realize the input and output of fault records and diagnosis through the I/O interface, and then form a CSV file. The user can achieve the above functions by touching the HMI display. Therefore, the HMI serves as the monitoring screen of the PIS system by reading the PIS system The video data of the camera can be displayed on the HMI display in full screen or quarter screen to display the surveillance video captured by the camera.

The control method of the network fusion system provided in this embodiment, while the CCU controls the operation of the train, and monitors the passenger information in the car to obtain the status information and passenger information of the train operation, and then the CCU passes the status information and passenger information through the switch Sent to HMI to make HMI display status information and passenger information.
