Fig. 2 is theory diagram of the present invention.
Embodiment
Following embodiment is only explanation technical conceive of the present invention and feature, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention enforcement according to this, can not limit the scope of the invention with this.All equivalents that Spirit Essence is made according to the present invention or modification, within all should being encompassed in protection scope of the present invention.
As shown in Figure 1 and Figure 2, a kind of train power supply cabinet of the present invention, it comprises: control loop and major loop, and described control loop is comprised of liquid crystal display and two set control systems, and this control system is comprised of power panel, switch template, change-over panel, control panel and comprehensive plate; Described major loop is comprised of ac input circuit, SCR rectification circuit, output filter circuit, vacuum contactor, fuse, banister switch and input voltage sensor, input current sensor, output voltage sensor, output current sensor and ground voltage sensor, this train power supply cabinet also comprises train network PORT COM, by train network PORT COM, to driver and conductor, passes on various operation informations.
Output terminal by ac input circuit is installed input voltage sensor and input current sensor and is connected, detects input voltage and electric current, shows numerical value, inputs overvoltage, under-voltage protection simultaneously, inputs overcurrent protection; By the output terminal at output filter circuit, voltage and current sensor are installed, are detected input voltage and electric current, show numerical value, export voltage stabilizing simultaneously, output overcurrent, short-circuit protection, realize the self check of train power supply cabinet system input/output state.
By comprehensive plate, control internal communication and external communication, control panel is controlled start logic manage, and controllable silicon triggers, by switch template control inputs output signal, detected, by change-over panel, controlled the conversion of sensor input signal, send into control panel sampling, by each circuit board of power panel, provide power supply, every circuit board is communicated with the master chip on comprehensive plate by CPU control while respectively, by the various information of master chip set and with display screen communication, because the set-up of control system in train power supply cabinet is identical mutually redundant two groups, A group and B group, redundancy each other, during the work of A group, whether every wiring board all detects on this wiring board input signal by CPU normal, if undesired, by B, organize detection, if A, B group all detects the fault of input signal, be defined as wiring board external signal fault, if it is normal that B group detects, be defined as A group corresponding line intralamellar part fault, realize the self check of each wiring board duty, cause two set control systems are redundancy each other, during Dang Yi road current supply circuit fault, another road still can be to train power supply, greatly improved the reliability of power supply system of train.
Driver and conductor inquires about as required overvoltage/undervoltage, excess current, voltage stabilizing value, earth leakage protection and is worth isoparametric setting value on liquid crystal display, can by button, on liquid crystal display, input web-privilege password Web simultaneously, and these parameters are set, and realizes the self check of feeding back in operational process, when system detects various faults, as input over-and under-voltage, input overcurrent, output overvoltage is under-voltage, output overcurrent, output short-circuit, leakage-current alarm, enable logic signal is not inconsistent, communication failure, internal module Circuit Board Trouble, contactor action failure, fuse damages, chopper switch is not closed, blower fan contactor fault, apparatus overheat etc., meeting Chinese display fault content on liquid crystal display, and fault-time and content are stored in CPU, simultaneously can Chinese prompt user, how to confirm fault, the method that prompting is fixed a breakdown etc., realize the self check of feeding back in operational process, when the communication network on system and locomotive does not connect, can show communication failure, whether the connector that prompting user detects communication is reliably connected with intact with circuit, and whether locomotive communication network is normal, determine whether it is the communication damage on equipment, thereby realize the self check of feeding back in operational process.
When driver and conductor sends enabling signal to equipment, this signal is transferred into train power supply cabinet control system, by train power supply cabinet control system, judge whether train possesses condition of power supply, simultaneously, by major loop, the present situation of train power supply cabinet is carried out the self check of feeding back in the self check of input/output state, the self check of each wiring board duty and various operational process, if run into self check complete do not find various abnormal, just start power supply.If find that there is, apply for the situations such as signal, fuse damage, chopper switch is not closed without powering, equipment can not start, and shows various signal conditions, and allowing user understand which kind of reason cannot start.
