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 motor train unit or subway train, the mode that acknowledgment button or foot-operated switch are set on driver controller is adopted to realize vigilant warning, under non-automatic driving model, when the speed of train is greater than zero-speed, driver presses acknowledgment button or makes emergency braking security loop keep electric with foot-operated firmly foot-operated switch, under automatic driving mode, the mode signal of automatic Pilot is used to keep emergency braking safety link rood electricity.
Current driver watches out for function and all realizes by hardware circuitry.Realize having some limitations and shortcoming by hardware circuitry, need to use electric capacity, resistance, relay building driver and watch out in the process of controlling functions, the even components and parts such as slug relay, and driver to watch out for function substantially always in running order in the operation process of vehicle, very high to the life requirements of components and parts, above-mentioned components and parts easy et out of order in use repeatedly every day, brings impact to operation.Meanwhile, the parameter of some components and parts is also also unstable, if the domain of walker of capacitance is usually-10% to+50%.
In addition, the vigilant functional circuit built with rigid line, vigilant guard time and all more single to the triggering mode of vigilant protection, as script function is: unclamp acknowledgment button and brake more than 4 seconds trigger emergency.If need to modify to the time of unclamping, as being adjusted to 40 seconds; Or change triggering mode, not only unclamp 40 seconds time-out will report to the police as made into, hold time-out also will report to the police for 40 seconds, and will provide sound and light alarm when unclamping or hold with a firm grip more than 30 seconds, this time, circuit originally just cannot realize, and not only needed to change components and parts, again circuit is built, and original circuit also can become very complicated, the reliability decrease of circuit, very inconvenient.。
Summary of the invention
The present invention wants technical solution problem to be: the shortcoming overcoming above-mentioned technology, provides a kind of driver's vigilance device of networking.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of driver's vigilance device based on train network, comprise with the network I/O module being connected to existing train main control unit by existing train network, the acknowledgment button be connected with the input end of described network I/O module, with described network I/O module the mouth vigilant trigger action relay, indicator lamp and the buzzer phone that are connected; Described vigilant trigger action relay, indicator lamp are connected by by-pass switch with train power supply with buzzer phone; Described acknowledgment button and described network I/O module are by described train Power supply; Described acknowledgment button is arranged in the operator's compartment of train.
Such scheme further improves and is: the zero-speed signal in existing train, acknowledgment button test signal, ATO driving model signal, driver's cab Seize ACK message pass through another network I/O model calling to existing train network, and then are connected with described train main control unit.
Such scheme further improves and is: described train power supply and be provided with circuit breaker between described acknowledgment button and by-pass switch.
Driver's vigilance device based on train network provided by the invention, utilizes existing train network, acknowledgment button signal is directly delivered to train main control unit, simplifies circuit structure greatly; Meanwhile, vigilant guard time and the adjustment to the triggering mode of vigilant protection also only can need complete in the operation of train main control unit, greatly reduce maintenance, use cost.
Accompanying drawing explanation
Fig. 1 is the present invention's preferred embodiment electrical block diagram.
Detailed description of the invention
Embodiment
The driver's vigilance device based on train network that the present embodiment provides, as shown in Figure 1, comprise with the network I/O module being connected to existing train main control unit VCU module by existing MVB train bus-line, the acknowledgment button be connected with the input end of network I/O module, with network I/O module the mouth vigilant trigger action relay, indicator lamp and the buzzer phone that are connected; Vigilant trigger action relay, indicator lamp are connected by by-pass switch with train power supply with buzzer phone; Acknowledgment button and network I/O module are by train Power supply; Acknowledgment button is arranged in the operator's compartment of train.
Zero-speed signal in existing train, acknowledgment button test signal, ATO driving model signal, driver's cab Seize ACK message pass through another network I/O model calling to existing train network, and then are connected with train main control unit.
Train power supply and be provided with circuit breaker between acknowledgment button and by-pass switch.
Train main control unit VCU module judges train current state according to the signal collected (zero-speed signal, acknowledgment button test signal, acknowledgment button operation signal, ATO driving model signal etc.), according to the vigilant function that will realize, provide the signal of vigilant warning and vigilant function.
By change train main control unit VCU module installation, time and the vigilant triggering mode of reporting to the police of vigilant protection freely can adjust according to disparity items, again need not change circuit again, also need not re-start the type selecting of components and parts again according to disparity items, convenient and swift.
Driver is operated by acknowledgment button, once there is emergency, namely train main control unit VCU module to give the alarm signal jointly by vigilant trigger action relay, indicator lamp and buzzer phone.
After emergency is removed, the power supply of vigilant trigger action relay, indicator lamp and buzzer phone can be stopped by by-pass switch, 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 embodiments.All employings are equal to the technical scheme of replacing and being formed, and are the protection domain of application claims.
