Above-mentioned master machine control unit is responsible for obtaining to the slave acquiring unit data of pantagraph current collector, and then judge whether breaking down of pantagraph current collector according to the data that get, based on this, the master machine control unit of the present embodiment can comprise following each subelement: obtain subelement, be used for receiving the data of the pantagraph current collector that detects from the slave control module corresponding with the address code of appointment after sending the address code of an appointment to each slave control module; Subelement relatively is used for obtaining respectively current value that subelement gets and magnitude of voltage and the maximum voltage value at the lowest high-current value of the pantagraph current collector main circuit that sets in advance and fuse two ends compares; Determine subelement, be used for when the current value that gets and magnitude of voltage exist at least one to surpass the lowest high-current value that sets in advance or magnitude of voltage the time, definite slave control module connected pantagraph current collector corresponding with the address code of appointment breaks down.
Fig. 3 is the structured flowchart of the master machine control unit of the utility model embodiment.
Whether understand in real time the train pantagraph current collector for the ease of train crew member or driver works, above-mentioned master machine control unit can also comprise: display 34, when communication module 31 receives address code, current value and magnitude of voltage from the slave control module, be used for showing these Value faults prompting subelements, be used for sending alarm when determining that the connected pantagraph current collector of the slave control module corresponding with the address code of appointment breaks down.Herein, the prompting of fault specifically adopts master machine control unit driving active buzzer 33 to realize.Adopt this fault prompting subelement train crew member or driver can know in real time the pantagraph current collector position ON TRAINS that whether has pantagraph current collector to break down and break down, conveniently the pantagraph current collector that breaks down is in time processed.
As the reference value whether pantagraph current collector works, can set in advance the maximum voltage value at fuse two ends of lowest high-current value that pantagraph current collector can bear, pantagraph current collector and the time value that train is crossed maximum trackless district in master machine control unit.Therefore the master machine control unit of the present embodiment can also comprise following each subelement: the input subelement is used for the maximum voltage value at lowest high-current value, fuse two ends of the pantagraph current collector main circuit that input sets in advance and the time value that train is crossed maximum trackless district; This input subelement adopts button 35 as shown in Figure 3 to realize.Wherein button can adopt function button ,+button ,-button and four buttons of definite button, pantagraph current collector main circuit lowest high-current value and and train cross the time value in maximum trackless district and fuse fusing voltage by key-press input, be kept in the EEPROM of microcomputer control unit.
Preserve subelement, be used for preserving the maximum voltage value at lowest high-current value, fuse two ends of the pantagraph current collector main circuit that sets in advance and the time value that train is crossed maximum trackless district, this preservation subelement is specifically as follows the EEPROM of microcomputer control unit.Wherein, the lowest high-current value of pantagraph current collector can be determined according to configuration mode, train traction stalling current characteristic and the 3rd rail trackless section length of train main circuit, the magnitude of voltage of fuse two ends maximum is the fusing voltage of fuse, train is crossed the time value in maximum trackless district can be according to train running speed, and the 3rd rail non-Electric region length is determined.The time value that master machine control unit need to be crossed maximum trackless district with train is as regularly to time interval that the slave control module obtains the pantagraph current collector request of data.
Particularly, master machine control unit proceeds as follows the packet from the slave control module that receives:
Address value, magnitude of voltage and the current value that receives is reduced into the front numerical value of slave control module coding, and namely the address value of slave control module, be also the address value of corresponding pantagraph current collector and magnitude of voltage and the current value that the slave control module monitors.
With odd number address date and the separately storage of even number address date.Because the 3rd rail is a monolateral left side or the right side that is laid on rail.Therefore in the process of vehicle operating, only have the pantagraph current collector of a certain side to carry out being flowed, have electric current to pass through.Electric current on the opposite side pantagraph current collector is zero.Therefore, master machine control unit before the fault judgement, can be that the current value of odd number carries out exclusive disjunction with address code, if the result after computing is zero, under the expression present case, this side does not have the 3rd rail, and pantagraph current collector is not subjected to stream work yet.Master machine control unit does not carry out next step judgement to this side data.
Master machine control unit is presented at magnitude of voltage and the current value of monitoring on LCD display, and the value with magnitude of voltage and current value and setting compares simultaneously, and pantagraph current collector is carried out the fault judgement.When having fault to occur, when having any fault to occur, master machine control unit drives hummer and carries out alarm, and wherein, fault type and the failure code of pantagraph current collector are specifically as follows:
If the double current value that obtains is 0, the fuse front end is 0, and rear terminal voltage signal is normal.This moment, pantagraph current collector can't normally be flowed, and this fault may be because the collector shoe swing arm is severed, and can show that failure code is E01 this moment on display.If the current value at master machine control unit is double to be received pantagraph current collector two ends is zero, fuse front and back ends voltage signal is normal.Determine fuse blows, cause electric current can't be circulated to main circuit, test can show on display that failure code is E02.If the electric current of the double pantagraph current collector that receives of master machine control unit surpasses maximum circuit, can determine cable failure, Leakage Current is excessive, and can show that failure code is E03 this moment on display.When if master machine control unit and appendent computer system communicate, if after master machine control unit sent the slave addresses code, main frame transferred receive status to, after waiting for the regular hour, beam back data if confiscate slave.Main frame can send the primary address code, and again is converted to receive status, if still for to receive the data that slave is beamed back, thinks communication failure between main frame and this slave.Communication line damages or slave control module fault E04.
