Problems solved by technology
[0003] 1. Lack of state information collection of key control execution components (such as 1C-6C, QC, LLC, LC, DLS, etc.), it is impossible to judge whether the components are working normally, and it is impossible to obtain the diesel engine speed, main engine excitation current, main Collect information such as output current and voltage, total wind pressure, and air compressor working status. When the main circuit of the locomotive fails, it cannot provide emergency travel plans for the drivers and passengers in time.
[0004] 2. The contacts of the intermediate control relay have virtual connections and faults, which may easily cause the shutdown or unloading of electrical equipment
[0005] 3. Shutdown or unloading of diesel engine due to oil pressure fluctuation
[0006] 4. It does not have the function of digital network transmission, and cannot provide real-time synchronization information of the main circuit of the locomotive for the background commanders
[0010] Although there are methods or devices for protecting the main circuit of the locomotive in the prior art, they cannot monitor and control the main circuit of the locomotive in an emergency

The invention discloses a system and a method for state monitoring and emergency control of an internal combustion locomotive. The system comprises a mainboard. The system has the characteristics of further comprising a PCPU control plug-in, an AMI plug-in, a DIO plug-in and a control display. The PCPU control plug-in is connected with a DC110V power supply of the locomotive. The AMI plug-in is connected with the main circuit of the locomotive, and is used for acquisition of locomotive analog quantity parameters and pulse quantity parameters, digital filtering processing, A / D conversion and pulse counting. The DIO plug-in is connected with the main circuit of the locomotive, and is used for receiving locomotive control instruction input, locomotive state switching quantity signals, statusreturns of action actuator such as contactors. The control display is installed in a cab. The PCPU control plug-in, the AMI plug-in and the DIO plug-in are plugged in the mainboard respectively. The AMI plug-in and the DIO plug-in are connected with the PCPU control plug-in through a CAN bus. The PCPU control plug-in is in signal communication connection with the control display and a CDM remote communication device. According to the system and the method for state monitoring and emergency control of the internal combustion locomotive, the real-time control state monitoring on the main circuitof the locomotive and the emergency control of the main circuit of the locomotive are realized, so that the control reliability of main circuit of the locomotive is improved.
Description
technical field [0001] The invention relates to a state monitoring and emergency control system and method of a diesel locomotive, which are used for monitoring the main circuit control of the locomotive, quickly judging faults, and jumping faulty nodes. Background technique [0002] To achieve different circuit functions, the main circuit of the locomotive includes a rectifier unit, an intermediate DC link of a chopper unit, an inverter circuit, etc. Therefore, the composite busbar connected to the main circuit also includes various types, such as: rectifier + chopper module Composite busbars, inverter module composite busbars, and capacitor busbars connected to intermediate support capacitors, etc. The control and monitoring of the main circuit of DF4 locomotive mainly have the following defects: [0003] 1. Lack of state information collection of key control execution components (such as 1C-6C, QC, LLC, LC, DLS, etc.), it is impossible to judge whether the components are...
