Abstract
The invention relates to a driver alarming device based on a train network, and belongs to the technical field of subway trains. The device comprises network I/O modules, an alarming button, an alarming trigger relay, an indicting lamp and a buzzer. The network I/O modules are connected to an existing train master control unit through the existing train network. The alarming button is connected with the input end of one network I/O module. The alarming trigger relay, the indicating lamp and the buzzer are connected with the output end of one network I/O module. The alarming trigger relay, the indicating lamp and the buzzer are connected with a train power source through a by-pass switch. The alarming button and the network I/O modules are powered by the train power source. The alarming button is arranged in a cab of a train. By means of the driver alarming device based on the train network, the existing train network is utilized for directly transmitting an alarming button signal to the train master control unit, and the circuit structure is greatly simplified. Meanwhile, alarming protection time and adjustment on the trigger mode of alarming protection can be completed simply by operating the train master control unit, and maintenance and use cost is greatly lowered.
Description
Technical field
The present invention relates to a kind of driver's vigilance device based on train network, belong to subway train technical field.
Background technology
Existing EMUs or subway train, using the side arranging acknowledgment button or foot switch on driver controller
Formula realizing vigilant warning, under non-automatic driving model, when the speed of train is more than zero-speed, driver press acknowledgment button or
Brake hard security loop is made to be kept as electricity with foot-operated firmly foot switch, under automatic driving mode, using the mould of automatic Pilot
Formula signal come to keep brake hard safety collar rood electricity.
Current driver watches out for function and is all realized with hardware circuitry.With hardware circuitry realize have some limitations and
Shortcoming, needs to use electric capacity, resistance, relay, or even time-delay relay etc. building during driver watches out for control function
Components and parts, and driver watches out for function and is substantially constantly in working condition during the operation of vehicle, will to the life-span of components and parts
Ask very high, above-mentioned components and parts easily break down in daily use repeatedly, bring impact to operation.Meanwhile, some units device
The parameter of part is also and unstable, and such as the domain of walker of capacitance is generally -10% to+50%.
Additionally, the vigilant functional circuit built with rigid line, vigilant guard time and to the triggering mode of vigilant protection all than
More single, such as script function is: unclamps the acknowledgment button brake hard of the triggering more than 4 seconds.If necessary to repair to the time of unclamping
Change, be such as adjusted to 40 seconds；Or change triggering mode, such as makes into not only to unclamp 40 seconds time-out and will report to the police, and holds time-out 40 seconds
Sound and light alarm to be provided, this when, the circuit of script just could when reporting to the police, and unclamp or hold with a firm grip more than 30 seconds
Realize, not only need to change components and parts, again build circuit, and original circuit also can become very complicated, circuit
Reliability decrease, very inconvenient..
Content of the invention
The invention solves the problems that technical problem is: the shortcoming overcoming above-mentioned technology, provide a kind of driver of networking to watch out for dress
Put.
In order to solve above-mentioned technical problem, technical scheme proposed by the present invention is: a kind of driver police based on train network
Cautious device, including with the network i/o module being connected to existing train main control unit by existing train network and described network i/
The acknowledgment button that the input of o module connects and described network i/o module outfan be connected vigilant trigger relay,
Display lamp and buzzer；Described vigilant trigger relay, display lamp and buzzer are connected by by-pass switch with train power supply；Institute
State acknowledgment button and described network i/o module is powered by described train power supply；Described acknowledgment button is arranged at the driver's cabin of train
Interior.
Such scheme is further improved by: the zero-speed signal in existing train, acknowledgment button test signal, ato drive
Sail mode signal, drivers' cab Seize ACK message is connected to existing train network by another network i/o module, so with described row
Car main control unit connects.
Such scheme is further improved by: is provided between described train power supply and described acknowledgment button and by-pass switch
Chopper.
The driver's vigilance device based on train network that the present invention provides, using existing train network, by acknowledgment button
Signal is fed directly to train main control unit, greatly simplified circuit structure；Meanwhile, vigilant guard time and to vigilant protection
Triggering mode adjustment also only need to train main control unit operation can complete, greatly reduce maintenance, use cost.
Brief description
Fig. 1 is one preferred embodiment electrical block diagram of the present invention.
Specific embodiment
Embodiment
The driver's vigilance device based on train network that the present embodiment provides, as shown in figure 1, include and by existing mvb
The network i/o module that train bus-line is connected to existing train main control unit vcu module is connected with the input of network i/o module
Acknowledgment button and network i/o module the outfan vigilant trigger relay, display lamp and the buzzer that are connected；Vigilant tactile
Send out relay, display lamp and buzzer to be connected by by-pass switch with train power supply；Acknowledgment button and network i/o module are by train
Power supply is powered；The driving that acknowledgment button is arranged at train is indoor.
Zero-speed signal in existing train, acknowledgment button test signal, ato driving model signal, drivers' cab Seize ACK message
Existing train network is connected to by another network i/o module, and then is connected with train main control unit.
It is provided with chopper between train power supply and acknowledgment button and by-pass switch.
Train main control unit vcu module (zero-speed signal, acknowledgment button test signal, vigilant is pressed according to the signal collecting
Button operation signal, ato driving model signal etc.) to judge train current state, according to vigilant function to be realized, be given vigilant
Warning and the signal of vigilant function.
By changing the setting of train main control unit vcu module, watch out for the time of protection and the vigilant triggering mode reported to the police can
Freely adjusted according to disparity items it is not necessary to again change circuit further according to disparity items, without re-starting components and parts again
Type selecting, convenient and swift.
Driver is operated by acknowledgment button, once emergency, train main control unit vcu module can be by police
Cautious trigger relay, display lamp and the common signal an alert of buzzer.
The confession of vigilant trigger relay, display lamp and buzzer after emergency releases, can be terminated by by-pass switch
Electricity, and then stop alarm.
The present invention is not limited to the concrete technical scheme of above-described embodiment, and in addition to the implementation, the present invention can also have
Other embodiment.The technical scheme that all employing equivalents are formed, is the protection domain of application claims.
