Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Fig. 1 is a schematic structural diagram of a flute control apparatus according to an embodiment of the present application.

Referring to fig. 1, the present application provides a siren control apparatus, which may include:

one-position whistle 110, two-position whistle 120, LCU200, and target unit 300;

the LCU includes a first output 210 and a second output 220, the first output 210 is connected to the one-bit flute 110, and the second output 220 is connected to the two-bit flute 120;

LCU200 is communicatively coupled to target unit 300; the LCU200 is configured to receive control information transmitted from the target unit 300 and control the first output terminal 210 or the second output terminal 220 to output a high level for activating the siren based on the control information.

The electric whistle control apparatus according to the present embodiment may be applied to electric whistles of various railway vehicles such as trams, subway trains, light rail traffic, and the like.

The one-position-

end whistles

110 and 120 in this embodiment may be a whistle located at one-position end of the railway vehicle and a whistle located at two-position end of the railway vehicle, respectively.

The LCU200 in this embodiment may include at least two output terminals, and in this embodiment, only the first output terminal 210 and the second output terminal 220 are taken as examples. The first output terminal 210 may be connected to the one-bit whistle 110 through a hard wire, and the second output terminal 210 may be connected to the two-bit whistle 120 through a hard wire.

The communication connection between the LCU200 and the target unit 300 in this embodiment may include a wireless connection, such as a bluetooth connection, a wifi connection, an NFC connection, a ZigBee connection, and the like, and a wired connection, such as a network cable connection, and the like. The LCU200 receives control information from the target unit 300 through the communication connection and controls the one-bit siren 110 or the two-bit siren 120 based on the control information. For example, when the railway vehicle is unmanned, if the control information sent by the target unit 300 includes an instruction to activate the one-bit electric whistle, the LCU200 receives the control information through the communication connection, and then controls the first output terminal 210 to output a high level for activating the electric whistle to the one-bit electric whistle 110, so that the one-bit electric whistle 110 is activated to perform whistling.

According to the flute control device provided by the embodiment of the invention, the LCU200 is respectively connected with the two unit-end flutes, and the LCU200 activates the flute according to the received control information from the target unit 300, so that the flute can be controlled under the condition of not relying on manual control or prerecorded flute working level, and the flexibility and reliability of flute control are effectively increased.

Fig. 2 is a second schematic structural diagram of the whistle control device according to the embodiment of the present application, as shown in fig. 2, the whistle control device may further include

power supply units

4100 and 4200, a first control switch 510, and a second control switch 520;

one end of the first control switch 510 is connected to the power supply unit 4100, and the other end is connected to the one-bit electric whistle 110;

one end of the second control switch 520 is connected to the power supply unit 4100, and the other end is connected to the two-terminal siren 120.

The

power supply units

4100, 4200 referred to in the present embodiment supply power to all devices when the vehicle is running. The

power supply units

4100, 4200 may be on-board power supplies of rail vehicles, further the power supply unit 4100 may be a positive power supply, such as DC110v+, and the power supply unit 4200 may be a negative power supply, such as DC110V-.

One end of the first control switch 510 is connected to the power unit 4100, the other end is connected to the one-bit electric whistle 110, the first output end 210 of the LCU200 and the first control switch 510 are connected in parallel, one end of the second control switch 520 is connected to the power unit 4100, the other end is connected to the two-bit electric whistle 120, and the second output end 220 of the LCU200 and the second control switch 520 are connected in parallel.

Because the first control switch 510 and the second control switch 520 are connected in parallel outside the LCU200 control whistle line, when communication between the LCU200 and the target unit 300 is abnormal, a driver of the railway vehicle at one position can control the one-position whistle 110 by controlling the opening and closing of the first control switch 510, and the driver of the railway vehicle at two position can control the two-position whistle 110 by controlling the opening and closing of the second control switch 520, thereby ensuring that manual control of the whistle can be still realized under the condition of abnormal communication between the LCU200 and the target unit 300.

According to the electric whistle control equipment provided by the embodiment of the application, the manual control switch is arranged in parallel with the two output ends of the LCU200, so that the electric whistle can still be manually controlled to whistle under the condition that the operation of the LCU200 is abnormal, the fault tolerance of the LCU200 is increased, the flexibility and the adaptability of the electric whistle under various operation conditions are enhanced, and the reliability of the electric whistle operation is improved.

Fig. 3 is a schematic diagram of a target unit provided in an embodiment of the present application, and as shown in fig. 3, a target unit 300 may include any one of the following:

a vehicle control apparatus 310;

the train automatic control system ATC320;

the vehicle control unit VCU330, the VCU330 being communicatively coupled to at least one of the vehicle control device 310 and the ATC320.

The target unit 300 that transmits control information to the LCU200 referred to in the present embodiment may be a vehicle control device 310, such as a human-machine interaction interface (Human Machine Interface, HMI) unit, an air-conditioning control unit, a brake control unit, a lighting control unit, or the like.

For example, when the brake control unit detects that the train brakes abnormally, the brake control unit may send control information to the LCU200 to instruct the LCU200 to control the one-position siren 110 or the two-position siren 120 to sound a warning.

The target unit 300 that sends control information to the LCU200 referred to in this embodiment may also be an ATC320. The ATC may include, among other things, a plurality of subsystems, such as a train autoguard (Automatic Train Protection, ATP) subsystem, a train autopilot (Automatic Train Operation, ATO) subsystem, a train automatic monitoring (Automatic Train Supervision, ATS) subsystem, and the like.

For example, when an ATP subsystem in ATC320 monitors that the train is in an overrun condition, ATC320 may send control information to LCU200 to instruct LCU200 to control one-bit end siren 110 or two-bit end siren 120 to sound a siren alert.

The target unit 300 that sends control information to the LCU200 referred to in this embodiment may also be the VCU330.VCU330 may be communicatively coupled to at least one of vehicle control device 310 and ATC320.

For example, when the brake control unit of the vehicle control device 310 monitors that the braking of the train is abnormal during the unmanned process, the brake control unit may send control information to the VCU330, and the VCU330 may send the control information to the LCU200 to instruct the LCU200 to control the one-position whistle 110 or the two-position whistle 120 to sound a whistle.

Alternatively, when the ATP subsystem in the ATC320 monitors that the train is in an overrun condition, the ATC320 may send control information to the VCU330, and the VCU330 may send the control information to the LCU200 to instruct the LCU200 to control the one-bit siren 110 or the two-bit siren 120 to signal a siren.

According to the flute control equipment provided by the embodiment of the application, communication connection is established between the LCU200 and the plurality of target units 300, so that the control requirements on the flute in various operation modes can be realized, the fault tolerance rate of the target units 300 for controlling the LCU200 to blast the flute is improved, the flexibility and the adaptability of the flute under various operation conditions are enhanced, and the operation reliability of the flute is improved.

In one embodiment, LCU200 may be specifically used to:

in the case that the one-bit terminal is occupied and the control information includes a request to activate the one-bit terminal siren 110, the LCU200 controls the first output terminal 210 to output a high level;

in the event that the two-bit terminal is occupied and the control information includes a request to activate the two-bit terminal siren 120, the LCU200 controls the second output 220 to output a high level.

It should be noted that, when the train traveling direction is the direction in which the one-bit electric whistle 110 is located, the one-bit electric whistle is occupied, and if the LCU200 receives the control information from the target unit 300 to request to activate the one-bit electric whistle 110 at this time, the LCU200 controls the first output terminal 210 to output a high level to activate the one-bit electric whistle 110.

Similarly, when the train traveling direction is the direction in which the two-level siren 120 is located, that is, the two-level siren is occupied, if the LCU200 receives the control information from the target unit 300 to request to activate the two-level siren 120 at this time, the LCU200 controls the second output terminal 220 to output the high level to activate the two-level siren 120.

It will be appreciated that when the target unit 300 sends a control message requesting activation of the siren 120 when the rail vehicle is one-bit, the LCU200 will ignore the control message. The same applies when the rail vehicle is occupied by two ends, and the description thereof is omitted.

The following describes the various modules in LCU200 and the processing flow within LCU200 after receiving control information.

Fig. 4 is a schematic structural diagram of a vehicle logic control unit provided in an embodiment of the present application, and as shown in fig. 4, an LCU200 may include a power board 230, a main control board 240, a communication board 250, an IO board 260, a patch board 270, and a first output terminal 210 and a second output terminal 220.

The power panel 230 is used for connecting a vehicle power supply and converting the vehicle power supply into a power level used by other boards to supply power for the other boards; the main control board 240 is responsible for logic operation processing; the communication board 250 is responsible for communication with the target unit 300; the IO board 260 is responsible for monitoring the input and output states of the patch board 270 and performing state visualization; the patch panel 270 is responsible for connecting the vehicle hard-wired input and output, i.e., the patch panel connects the first output 210 and the second output 220.

Taking the processing flow in the LCU200 in the whistling process of the one-bit electric whistle 110 as an example, the power board 230 supplies power normally, the patch board 270 is connected to the first output end 210, the io board monitors and displays that the first output end 210 is connected normally, at this time, after the communication board 250 receives the control information from the target unit 300, the control information is transmitted to the main control board 240, the main control board 240 determines whether the control information received by the communication board 250 meets the whistling requirement according to preset logic, and after the main control board 240 determines that the whistling condition is met, the main control board 240 controls the patch board 250 to output a high level to the first output end 210, so that the one-bit electric whistle 110 can whistle normally.

The process flow in the LCU200 during the whistling of the two-position-terminal whistle 120 is the same and will not be described again here.

It will be appreciated that the main control board in the LCU200 may perform logic processing, so that the LCU200 has a separate logic processing capability, and the LCU200 can control the high-low level to make the one-two-level whistle and the two-level whistle, so that the LCU200 has a driving capability in addition to the logic processing capability.

To further illustrate the siren control device provided in the embodiments of the present application, the following describes the communication logic between the LCU200 and the target unit 300 by taking the HMI unit to trigger the LCU200 to control the siren to sound.

For example, the signal sent by the HMI unit to the LCU200 to control the whistle 110 to whistle is represented by variable horn1_hmiact, and the signal to control the whistle 120 to whistle is represented by variable horn2_hmiact, which may be a network input signal;

the signal that the one-bit end occupies access to the LCU200 may be represented by a variable accpuy 1, the signal that the two-bit end occupies access to the LCU200 may be represented by a variable accpuy 2, and the signal may be a hard-wired input signal;

after LCU200 receives the control information, the output signal of activating one-bit-end whistle 110 may be represented by variable horn1_actx1, the output signal of activating two-bit-end whistle 120 may be represented by variable horn2_actx1, and the output signal may be a hard-wire output signal;

the LCU includes a first output 210 and a second output 220, where the first output 210 is connected to the one-bit flute 110 and the second output 210 is connected to the two-bit flute 120, and the connection may be a hard-wired connection.

When the one-bit electric whistle 110 needs to be activated, the HMI unit sends a signal horn1_hmiact for controlling the one-bit electric whistle 110 to blast to the LCU200, at this time, the LCU200 checks that the one-bit end occupation signal Occpuy1 is normal, and accords with the condition for controlling the one-bit electric whistle 110 to blast, and the LCU200 controls the first output terminal 210 to be set at a high level by activating the output signal horn1_actx1 of the one-bit electric whistle 110, so that the one-bit electric whistle 110 blasts.

The two-position whistle 120 whistle logic is the same and will not be described in detail herein.

To further illustrate the communication logic between the LCU200 and the target unit 300, the ATC320 and VCU330 control the LCU200 to blast.

For example, the signal from the VCU330 that the ATC320 activates the one-bit end flute 110 may be represented by a variable horn1_atcact, and the signal from the ATC330 that activates the two-bit end flute 120 may be represented by a variable horn2_atcact, which may be a network input signal;

the LCU200 includes a first output end 210 and a second output end 220, where the first output end 210 is connected to the one-bit flute 110, and the second output end 220 is connected to the two-bit flute 120, and the connection may be a hard wire connection;

the Remote Input/Output Module (RIOM) may transmit signals of "one-bit end occupied" and "two-bit end occupied" to the ATC200;

the vehicle signaling system may signal an ATC blast request when the vehicle has a blast demand.

When the vehicle is in the fully automatic mode of operation, the ATC200 has a one-bit end whistle 110 whistle request, the vehicle signaling system issues an ATC200 whistle request signal, at which time the RIOM signal indicates "one-bit end occupied", and the VCU330 receives all acknowledgement signals from the ATC 320: after the "full-automatic operation mode", "ATC blast request" and "one-bit end occupation", a control signal horn1_atcact for activating the one-bit electric flute 110 by the ATC320 is sent to the LCU200, and after the LCU200 receives the signal, the first output end 210 is controlled to be placed at a high level by activating the output signal horn1_actx1 of the one-bit electric flute 110, so that the one-bit electric flute 110 blasts.

According to the whistle control equipment provided by the embodiment of the application, whether the control information received by the LCU200 from the target unit 300 accords with the whistle activating condition is judged through the preset processing logic in the LCU200, so that the control requirement on the whistle in the full-automatic operation mode of the vehicle is met, the correctness of the whistle-whistling direction is ensured, the whistle can still work normally under the unmanned condition, the flexibility and the adaptability of the whistle under various operation conditions are enhanced, and the operation reliability of the whistle is improved.

In one embodiment, where the target unit 300 includes a VCU330, the LCU200 is further configured to receive update information sent by the VCU330 and update control logic for the one-bit end whistle 110 and/or the two-bit end whistle 120 based on the update information.

Because a communication connection is established between the LCU200 and the VCU330, when the logic of the LCU200 controlling the one-bit electric flute 110 and/or the two-bit electric flute 120 needs to be updated, update information may be sent to the LCU200 through the VCU330, and the LCU200 updates the control logic of the one-bit electric flute 110 and/or the two-bit electric flute 120 after receiving the update information sent by the VCU330.

According to the flute control equipment provided by the embodiment of the application, the communication connection is established between the LCU200 and the VCU330, so that the problem that the traditional flute control system is complicated in upgrading steps is solved, a technician can realize the upgrading of the flute control logic only by remote control, the workload of the technician is saved, the logic updating process of the LCU200 is simplified, and the operation and maintenance cost of a vehicle is reduced.

In one embodiment, the siren control device further includes a database communicatively coupled to the LCU200 and the target unit 300, respectively;

the database is used for storing the operation data of the LCU and the target unit, and the operation data is used for diagnosing faults of the whistle control equipment.

The database in the siren control apparatus according to the present embodiment may use various types of databases, for example, redis, mySQL, oracle, etc., and is not limited thereto.

Because the database is respectively connected with the LCU200 and the target unit 300 in a communication manner, the operation data of the LCU200 and the target unit 300, such as the sending/receiving information, the communication time, the communication type, whether the communication is completed, the information content processed by the LCU200, the processing result and other detailed records, can be used for locating and repairing the fault by combining the database information with the actual situation when the fault occurs in the working process.

For example, when the VCU330 transmits the "ATC activates one-bit-end flute" signal normally, the database record information "VCU transmits the" ATC activates one-bit-end flute' signal normally "; when the VCU330 should send the "ATC activate one-bit-end whistle" signal but not send it successfully due to a fault, the database record information "VCU sends the" ATC activate one-bit-end whistle "signal is abnormal".

The technician can clearly determine the cause of the fault by the information record of the database, namely, "the VCU sends 'ATC activates the one-bit flute' signal is abnormal", so that the technician can repair the fault by overhauling the VCU330.

According to the flute control equipment, the historical operation data between the LCU200 and the VCU330 are recorded through the database, the problems that the fault positioning is difficult and the time for repairing the loophole is long are solved, so that a technician can conveniently and rapidly position the fault occurrence reason only through the record of the database, the operation and maintenance efficiency is improved, and the operation and maintenance cost of a vehicle is reduced.
