Technical Field

[0001] The utility model belongs to the technical field of train operation safety, and in particular relates to a train control state monitoring system for LKJ train control equipment. Background Art

[0002] LKJ (Train Operation Monitoring Device) train control equipment is an important safety equipment for train operation. When the LKJ train control equipment is in a power-off state or non-service state, the train TCMS (Train Control and Management System) cannot obtain the working status of the LKJ train control equipment, causing the train to run without protection, posing huge risks and hazards to driving safety.

In the description of the utility model, it should be noted that the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0015] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0016] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] Embodiment 1: As shown in the drawings of the specification, the LKJ train control equipment vehicle control state monitoring system includes LKJ train control equipment, TCMS1, and also includes a control module 1, an acquisition module 2, a transmission module 4 and a storage module 5 that are connected to TCMS1 in communication. The control module 1 includes a high-performance GD32F450 as a main control CPU, the acquisition module 2 includes a current sensor and a monitoring unit in TCMS1 for obtaining real-time information of the LKJ train control equipment, the monitoring unit is connected to the control module 1 through CAN communication, the transmission module 4 includes a dry contact that is connected to the control module 1 in communication, and the storage module 5 includes an EMMC as a storage medium. The control module 1 is used for collecting and judging the power-off state and non-service state of the LKJ train control equipment, outputting the dry contact state, and processing information; the current sensor is used to monitor the power supply of the LKJ train control equipment, and determines whether the LKJ is in a power-off state by monitoring the current of the power line; the dry contact is connected to TCMS1 in communication, and the working state of the LKJ train control equipment is output to TCMS1; the storage module 5 is used to log the monitored data to provide a basis for subsequent problem finding.

[0018] Usage process: The acquisition module monitors the power supply of the LKJ train control equipment through the current sensor, and determines whether the LKJ is in a power-off state by monitoring the current of the power line; or obtains the real-time information of the LKJ train control equipment through CAN, and analyzes the CAN information content to determine whether the LKJ train control equipment is in the main duty or non-main duty state;

[0019] When the LKJ train control equipment is in a power-off or non-service state, the LKJ train control equipment has lost control of the train control. TCMS cannot obtain the working status of the LKJ train control equipment and will not perform speed limit control, resulting in the risk of overspeeding;

[0020] When it is detected that the LKJ train control equipment is in a power-off and non-service state, the transmission module (dry contact) is sent to TCMS. TCMS performs speed limit control according to the dry contact status to ensure driving safety.

[0021] The utility model is provided with a collection module for collecting the output current size of the power supply of the LKJ train control equipment and obtaining the real-time information of the LKJ train control equipment, and transmitting the above information to the control module. The control module determines whether the LKJ train control equipment is in a power-off state or a non-service state, and communicates with the TCMS through the transmission module to ensure that the LKJ train control equipment can perform automatic protection control even when it is in a power-off state or a non-service state.

[0022] The present invention is described in detail above through specific implementation methods and examples, but these do not constitute limitations of the present invention. Without departing from the principle of the present invention, those skilled in the art may make many modifications and improvements, which should also be considered as the protection scope of the present invention.
