Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The design concept of the whole frame of ACE designs around two-layer.The whole frame of Top-layer Design Method ACE comprises the special parameter of station aspect ACE frame, and bottom-layer design ACE frame comprises general ACE frame configuration.The design of ACE frame comprises the encapsulation of existing ACE 2-XX-RI/SSI subrack, ACE CPUs, power supply, I/O plate (the serial ports plate installed in ACE subrack and and oralia), a succession of PDCU (Power-Data Coupling Units power supply-data coupling unit), the interior connecting terminal block of different configuration and PLC (Programmable Logic Controller programmable logic controller (PLC)) module.
Refer to Fig. 1, ACE frame for parking area and car depot of the present invention, comprise the first power input terminal row 1, power data coupling unit 2, ACE subrack, second source Input terminal block 5, Interface Terminal row 6, power output terminal row 7 and signal output terminal row 8, wherein
First power input terminal row 1 connects power data coupling unit 2, ACE subrack and fan, and providing the power line voltage of 3 grades, is the 60VDC powered to ACE subrack respectively; To the 220VAC that fan is powered; By the 100VDC that power data coupling unit 2 powers to trackside meter shaft unit.
Power data coupling unit 2 also connects ACE subrack and trackside meter shaft unit, and trackside meter shaft unit provides data coupling signal and the power supply from the first power input terminal row 1, also for a series of I/O card of ACE subrack and trackside meter shaft unit provide connection; The fuse protection overvoltage protection of trackside wheel counting apparatus sensing point is provided simultaneously;
Second source Input terminal block 5 is with insurance, connects ACE subracks by Interface Terminal row 6, for providing the direct current (DC) interface of 24VDC between ACE subrack and relay rack system, and the overload protection simultaneously provided for ACE subrack and short-circuit protection; Signal output terminal row 8 connects ACE subrack and relay rack, and the power supply of ACE subrack and data-signal are exported to relay rack; Power output terminal row 7 connects ACE subrack, for providing the direct current (DC) interface of 0VDC between ACE subrack and relay rack system.
ACE subrack comprises serial ports plate module 3, parallel port plate module 4 and CPU board,
Serial ports plate module 3 can 2 axle-counting points outside sensing chamber, receive the information that power data coupling unit 2 transmits from trackside meter shaft unit, and this information is sent to CPU board by CAN interface by isdn interface;
In parallel port plate module 4, the corresponding outdoor section of every block oralia, by CAN interface between it and CPU board, what export that 2 group relay contacts (double break) indicate section takies/idle condition.
Refer to Fig. 2, principle of work of the present invention is as follows:
Trackside meter shaft unit sends electronic unit by two physical deflection coil magnetic heads and data acquisition and forms, and physical deflection coil magnetic head (meter shaft magnetic head) is arranged on same track.Being two Tx coils (primary winding) outside track, is two Rx coils (output primary) inside track, produces the two kinds of signals being about the different frequency of 30kHz, near track, forms electromagnetic field.These devices provide the induced voltage of two time migrations, utilize the travel direction that these devices just can determine whether by wheel shaft and wheel shaft in electronic unit.Based on reliability reasons, in magnetic head, except coil, there are not other electronic units.Electronic unit is that Tx magnetic head is powered, and detects and calculates wheel shaft pulse, monitoring magnetic head, carries out self-inspection and sends the message comprising counting and monitor message to power data coupling unit 2.Counting, monitoring and message systematic function are performed by two independent microcon-troller by the monitoring of meter shaft host security modules in serial ports plate module 3.Then by the number of axle that the outer meter shaft section of Evaluation Room counts and counts, parallel port plate module 4 judges whether secondary section takies the/free time, and data message is sent to relay rack by signal output terminal row 8.Relay rack, by showing track relay again, illustrates the state of two dry contacts to come again, then shows that the contact state of track relay takies the/free time again by interlocking collection.In addition, axle counting system parallel port plate module 4 can also export a non-security condition and be used for providing " section fault/disturbed state ", is selected for ATC system by signal output terminal row 8.If axle counting system does not detect meter shaft section " fault/disturbed ", then output state is high level.If axle counting system needs clearly under " fault/disturbed " state, then need interlock system to export a reset command to drive reset relay coil, after coil magnetization is picked up, two groups of contacts of adhesive reset relay input reset command and are given to module.
If be equipped with two cover meter shaft main frames in same interlocking limit, then as shown in Figure 3, wherein ACE1 and ACE2 reads the number of axle that shared magnetic head is reported to the connection mode between them simultaneously.
For two meter shaft main frames of different interlocking area, the connection mode between them as shown in Figure 4, namely two main frames simultaneously reading boundary share the number of axle information that axle-counting points reports.
Axle counting system and can close and provides taking of each meter shaft section and idle condition to interlocking equipment by the disconnection of two dry contacts.According to interlocking demand, it is identical that these two dry contacts both can be configured to logic, also can be configured to logic contrary (see truth table below).ATC system gathers these two dry contacts can by two kinds of modes: first kind of way is the state that interlocking directly gathers these two dry contacts; The second way is by showing track relay again, and the state of these two dry contacts is illustrated again, then shows the contact state of track relay again by interlocking collection.In addition, axle counting system can also export a non-security condition and be used for providing " section fault/disturbed state ", selects for ATC system.If axle counting system does not detect meter shaft section " fault/disturbed ", then output state is high level.Note: the present invention adopts the second interface mode.
To sum up, ACE frame of the present invention can coordinate arbitrary third party's interlock system to use together, is greatly improved in applicability.ACE frame of the present invention altogether can outer 32 axle-counting points of junction chamber and 26 track sections, more track section can be monitored, be more applicable to complicated car depot and the demand of field, parking station environment, reduce the rack quantity of canyon, improve the degree of utilization of rack, reduce costs.Meanwhile, ACE frame of the present invention eliminates some N/R Interface Terminals row, the larger space environment adding rack, has further lifting, improve reliability and the operating efficiency of equipment for heat radiation and on-the-spot construction.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
