Description

Technical Field

[0001] The present invention mainly relates to the field of rail transportation technology, and in particular to a testing device and a testing method for a platform door central control panel system. Background Art

[0002] The main functions of the Platform Edge Doors Central Control Panel (PEC) system are to receive door opening / closing commands from the Signal System (SIG) and send them to the Door Control Unit (DCU) to achieve automatic level control, while also feeding back platform door status information to the signal system. Existing technologies for testing the aforementioned functions of platform door central control panel systems often use debugging tools to simulate data transmission and reception in various scenarios based on communication protocols. This requires manual control of communication protocols and the construction of configuration data, making it impossible to intuitively obtain the status of vehicle doors and platform doors. This is especially true when there are a large number of platform doors, making the operation complex, inefficient, and time-consuming. Furthermore, due to limitations in indoor testing hardware (multiple network cards or serial ports), it is often impossible to test multiple simultaneous communication scenarios, limiting test applications.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 As shown, the test device of the platform door central control panel system according to the embodiment of the present invention includes a human-computer interaction module, a SIG simulation module, a DCU simulation module and a conversion module;

[0031] The human-computer interaction module is connected to the SIG simulation module and the DCU simulation module respectively. The SIG simulation module is connected to the platform edge door central control panel (PEC) system to be tested through the conversion module; the DCU simulation module is connected to the PEC system to be tested.

[0032] The human-computer interaction module is used to simulate and set various door states and send them to the SIG simulation module. The SIG simulation module forwards the door states to the platform door central control panel system via the conversion module. The platform door central control panel system sends the door states to the DCU simulation module. The DCU simulation module then sends the door states to the human-computer interaction module for display and verification. The simulated door states are automatically compared with the displayed door states to achieve automatic closed-loop testing of the door states of the platform door central control panel system under test and automatically generate a test report.

[0033] The human-computer interaction module is used to simulate the setting of various platform door states and send them to the DCU simulation module. The DCU simulation module sends the platform door state to the platform door central control panel system to be tested. The platform door central control panel system to be tested sends the platform door state to the SIG simulation module via the conversion module. The SIG simulation module then sends the platform door state to the human-computer interaction module for display and verification. The simulated platform door state is automatically compared with the displayed platform door state to realize automatic closed-loop testing of the platform door state of the platform door central control panel system to be tested and automatically generate a test report.

[0034] The present invention sets the status of all vehicle doors on both sides through the human-computer interaction module, and then sends it to the PEC system through the SIG simulation module and the conversion module. The PEC system receives the vehicle door status and forwards it to the simulation DCU module, and displays and automatically verifies it in real time on the interface of the human-computer interaction module, and automatically generates a test report. Similarly, the status of all platform doors on both sides is set through the human-computer interaction module, and then sends it to the PEC system through the DCU simulation module. The PEC system receives the platform door status and forwards it to the SIG simulation module, and displays and automatically verifies it in real time on the interface of the human-computer interaction module, and automatically generates a test report, thereby realizing testing and experimentation of the PEC system functions, communication interfaces and performance.

[0035] In a specific embodiment, the human-computer interaction module may adopt a KVM switch or a combination of a general-purpose LCD display, keyboard, and mouse, mainly to realize human-computer interaction control and monitoring; the door status may be set manually or automatically through the interface of the human-computer interaction module: including setting a single door status in sequence, and setting a combination of different door statuses, to realize a combination traversal of door statuses; and manually or automatically setting the platform door status: whether the platform doors on both sides (such as 48) are faulty, open, etc., including setting a single platform door status in sequence, and setting a combination of different platform door statuses, to realize a combination traversal of platform door statuses; in addition, the interface may also display the received door status and platform door status in real time.

[0036] In a specific embodiment, the conversion module is a converter, which uses the RSSP-1 protocol to package the door status data from the SIG simulation module and forward it to the PEC system, and parses the platform door status data from the PEC system according to the RSSP-1 protocol to obtain application data and forward it to the SIG simulation module.

[0037] In one specific embodiment, the conversion module is connected to the PEC system to be tested via two Ethernet interfaces; one Ethernet interface is connected to System I of the PEC system to be tested, and the other Ethernet interface is connected to System II of the PEC system to be tested. The two Ethernet interfaces are redundant with each other and transmit the same data to achieve dual-redundant interface and function testing.

[0038] In addition, the DCU simulation module is connected to the PEC system under test through four CAN interfaces; two CAN interfaces (such as CAN1 and CAN2) are connected to the I system of the platform door central control panel system under test, and the other two CAN interfaces (such as CAN3 and CAN4) are connected to the II system of the PEC system under test. CAN1 and CAN3 are redundant, and CAN2 and CAN4 are redundant, so as to realize the testing of dual redundant interfaces and functions.

[0039] The present invention supports multiple communication interfaces through configuration, meeting the requirements of multi-channel simultaneous communication between the PEC system and the SIG simulation module and the DCU simulation module. At the same time, the present invention also supports other communication modes, such as RS422 / 485, MVB, etc., and has good scalability. Ethernet and CAN interface parameters can be configured and edited through configuration files. When parameters such as the interface change, there is no need to modify the software code. Only the parameter configuration in the configuration file needs to be modified. The test device automatically reads the parameters in the configuration file when starting to perform the test, and the configuration is flexible. The door status or the shielded door status can be directly set through the interface, and the door status and platform door status forwarded by the PEC system are displayed in real time, which is highly flexible. All test operations are completed in a unified interface, which is easy to operate. The hard-wired interface and software functions are tested at the same time, various test scenarios are supported, and test reports are automatically generated, with high test efficiency.

[0040] An embodiment of the present invention further provides a testing method based on the testing device of the platform door central control panel system as described above, comprising the steps of:

[0041] The human-computer interaction module is used to simulate and set various door states and send them to the SIG simulation module. The SIG simulation module forwards the door states to the platform door central control panel system via the conversion module. The platform door central control panel system sends the door states to the DCU simulation module. The DCU simulation module then sends the door states to the human-computer interaction module for display and verification. The simulated door states are automatically compared with the displayed door states to achieve automatic closed-loop testing of the door states of the platform door central control panel system under test and automatically generate a test report.

[0042] The human-computer interaction module is used to simulate the setting of various platform door states and send them to the DCU simulation module. The DCU simulation module sends the platform door state to the platform door central control panel system to be tested. The platform door central control panel system to be tested sends the platform door state to the SIG simulation module via the conversion module. The SIG simulation module then sends the platform door state to the human-computer interaction module for display and verification. The simulated platform door state is automatically compared with the displayed platform door state to realize automatic closed-loop testing of the platform door state of the platform door central control panel system to be tested and automatically generate a test report.

[0043] The present invention targets the signal characteristics and test requirements of the platform door central control panel, and realizes testing of all platform doors, car doors, communication interfaces, and redundant functions on both sides of the platform door central control panel. It can test data forwarding of multiple doors and multiple states, has good scalability, flexible configuration, and can meet various test scenarios, thereby improving indoor test efficiency, quality, and test coverage, and reducing test costs. It has a high degree of functional integration, and test operations are all completed in a unified human-machine interface, which is easy to operate.

[0044] In a specific embodiment, according to the test requirements, it is necessary to accommodate 48 car doors and 48 platform doors on one interface at the same time, and to be able to set 8 status information of all platform doors (such as fault, open, manual mode, whether isolation is effective, etc.). If each platform door is set to 8 states, a total of 384 states need to be set, and the interface appears to be relatively dense and large, time-consuming, inefficient and tiring to the eyes. The present invention uses a method of sharing interface status resources to display all car door status information and platform door status information, making the interface simple and easy to operate. It can automatically test the status information of all car doors and platform doors or test the status information of single or multiple car doors and platform doors, and the platform door and car door status settings and displays do not affect each other. The principle of interface status resource sharing is as follows:

[0045] Consider each platform door as an object and all the states of the platform door as a structure. Each platform door has all the states, so each object has a structure.

[0046] When a platform door is selected, it is equivalent to selecting this object and setting the state. It changes the state of this object and has no effect on other platform doors. Figure 4 The solid line in the middle shows the selected platform door;

[0047] When another platform door is selected, the same status is set, which changes the status of the current platform door and has no effect on the previous and other platform doors;

[0048] All platform doors share the same state resource settings, which greatly saves interface space and makes the interface concise and easy to use.

[0049] The door status includes whether there is a door on one side, whether there is a door on the other side, whether there are doors on both sides, and whether the doors are isolated; the platform door status includes whether the platform door is faulty, locked, isolated, whether there is a configuration error, whether there is a configuration warning, whether it is in manual mode, whether it is manually released, whether there is emergency door feedback, etc.

[0050] In a specific embodiment, the process of implementing the platform door test CAN interface is as follows:

[0051] The DCU simulation module transmits the status of the platform doors on both sides to the two systems (System I and System II) of the PEC system through four CAN interfaces. The communication interface implementation scheme is as follows: Figure 2 As shown:

[0052] The human-computer interaction module sets different states (whether faulty, open, etc.) for the 24 platform doors on the left and right sides respectively, thereby generating the state data of the 24 platform doors on the left and the 24 platform doors on the right.

[0053] The status data of the 24 platform doors on the left are transmitted to the I and II systems of the PEC system via CAN1 and CAN3 respectively, ensuring that the data of the I and II systems are consistent and maintain a redundant relationship;

[0054] The status data of the 24 platform doors on the right side are transmitted to the I and II systems of the PEC system via CAN2 and CAN4 respectively, ensuring that the data of the I and II systems are consistent and maintain a redundant relationship;

[0055] Ultimately, both System I and System II of the PEC system can receive all platform door status data without interfering with each other, always maintaining a redundant relationship and remaining consistent with the on-site scenario. This allows for testing the redundant functions of the redundant system with a high test coverage rate.

[0056] In a specific embodiment, the process of implementing the door test CAN interface is as follows:

[0057] After the conversion module sends the 48 door status data on both sides to the I and II series of the PEC system, the PEC system transmits the door status on both sides to the DCU simulation module through four CAN ports. The communication interface implementation scheme is as follows: Figure 3 As shown:

[0058] The human-computer interaction module sets different states for the 24 doors on the left and right sides, generating state data for 48 doors on both sides, which are then sent to the two systems of the PEC system through the SIG simulation module and the conversion module.

[0059] The PEC system sends the status of the 24 doors on the left and the 24 doors on the right to the DCU simulation module through CAN1 and CAN2 respectively;

[0060] The PEC system sends the status of the 24 doors on the left and the 24 doors on the right to the DCU simulation module through CAN3 and CAN4 respectively;

[0061] Finally, the DCU system can receive two sets of left and right door status information and display them in real time on the interface of the human-computer interaction module, which is simple and intuitive.

[0062] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should be considered within the scope of protection of the present invention.
