Description

Portable train maintenance system based on wireless communication

Technical Field

The utility model belongs to the technical field of the train overhauls, more specifically relates to a portable train overhauls system based on radio communication.

Background

In recent years, due to the reasons of long online operation time of domestic trains, large number of trains, increased labor cost and the like, the concept of intelligent operation and maintenance is provided in the industry for improving the maintenance efficiency.

As shown in fig. 1, a general train is provided with an HMI (Human Machine Interface) in a cab, which can monitor the state of the train in real time, and at the same time, the train is provided with 1 to 2 ERs (Event recorder) in order to Record key state information and fault information of train operation. After the train breaks down, the staff checks the equipment state information through the display, and meanwhile, the maintainer uses a PTU (Portable Test Unit) to connect a data downloading interface on the train through a network cable, downloads data at the moment of the fault for analysis, and processes the data after determining the fault reason. In the analysis process, when the maintainers need to operate (reset equipment or throw away equipment) to confirm each compartment, people need to check the HMI in the cab to cooperate. When the maintenance personnel operate the carriage, the state of the train cannot be known in real time, and the time is consumed to go to a cab for confirmation; for the unmanned vehicle without HMI, the maintainer can not obtain the train state; the maintainer need carry the PTU and download the net twine, and is inconvenient.

Alternatively, as shown in fig. 2, another train maintenance system is composed of a vehicle-mounted HMI, an ER, a PTU, a wireless transmission device and a ground server. The train fault data and the state data are transmitted to the ground in real time through the wireless transmission device. After the fault occurs, the maintenance personnel analyze the fault reason through the ground data. In the analysis process, when the maintainers need to operate (reset equipment or throw away equipment) to confirm each compartment, people need to check the HMI in the cab to cooperate. According to the maintenance method of the system, when the maintenance personnel operate in the carriage, the state of the train cannot be known in real time, and time and resources are consumed to go to a cab for confirmation; for unmanned vehicles without HMI, the maintainers cannot obtain the train state; the data is downloaded to the ground in real time, and a large flow is consumed.

According to the above two existing modes, it generally takes 1-2 hours or more to solve a single fault, which is contrary to the goal of improving the overhaul efficiency at the present stage.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the technical problem that above-mentioned exists, a portable train overhauls system based on radio communication is proposed, through mobile device real-time observation train state to behind the accessible selection trouble, automatic download, analytic data form the report, practice thrift trouble solution time, promoted maintenance efficiency.

The utility model adopts the following specific technical proposal:

the utility model provides a portable train maintenance system based on radio communication, is including installing the time recorder in the train, still includes on-vehicle WIFI and portable removal test unit, on-vehicle WIFI is connected with the power, portable removal test unit and time recorder all insert on-vehicle WIFI, realize the correlation between them.

Preferably, the vehicle-mounted WIFI is accessed into a train communication network, so that the portable mobile testing unit can check the real-time state of the train through the vehicle-mounted WIFI.

Preferably, the portable mobile test unit is a smart phone.

Preferably, the portable mobile test unit is a tablet computer.

Preferably, the portable mobile test unit can directly generate a simple fault report.

Preferably, the fault report includes common faults of the brake system and solutions thereof.

Preferably, the portable train maintenance system further comprises a vehicle-mounted human-computer interaction interface.

Preferably, the vehicle-mounted man-machine interaction interface is connected with the display screen and can be applied to a cab of the manually driven train to monitor the state of the train in real time.

Preferably, the vehicle-mounted human-computer interaction interface is accessed to the vehicle-mounted WIFI, so that interface and data synchronization of the portable mobile testing unit and the vehicle-mounted human-computer interaction interface is realized.

The utility model has the advantages that:

(1) the maintenance efficiency is improved: the problem that the maintainers can observe the state of the train in real time when the maintainers carry out maintenance confirmation work on each carriage is solved, and the condition that the maintainers return to a cab to confirm the HMI state is avoided;

(2) a man-machine interaction interface is not needed, and the problem that no unmanned aerial vehicle interaction interface exists during the vehicle maintenance of the unmanned vehicle is solved;

(3) the PTU is light, light movable equipment is adopted as the PTU, and meanwhile, the number of equipment required by maintainers is reduced by wirelessly connecting a train;

(4) avoiding the flow consumption of a large amount of data which is issued to the ground in real time;

(5) and fault data are automatically downloaded and analyzed, data screenshot is realized, a simple report is formed, and the overhaul time is saved.

Detailed Description

The invention will be further described with reference to specific examples. The starting materials and methods employed in the examples of the present invention are those conventionally commercially available in the art and those conventionally used unless otherwise specified.

Example 1

As shown in fig. 3, a portable train maintenance system based on wireless communication, including installing time recorder (ER), on-vehicle WIFI and the power in the train, portable removal test unit (remove PTU, smart mobile phone or panel computer etc.) and on-vehicle human-computer interaction interface (HMI), on-vehicle HMI connects the display screen (can look over train running state in the cab), on-vehicle WIFI is connected with the power, portable removal test unit, time recorder and on-vehicle human-computer interaction interface all can access on-vehicle WIFI.

After a fault occurs, a maintainer gets on the train, the vehicle-mounted WIFI is powered on, the mobile PTU is connected with the vehicle-mounted WIFI, the vehicle-mounted HMI monitors the state of the train in real time, the interface and data synchronization is realized between the mobile PTU and the vehicle-mounted HMI, after a corresponding fault is clicked and selected, the mobile PTU automatically downloads data and analyzes the data at the moment of the fault, the fault at the moment of the fault is associated with the state data, and a simple fault report is formed. The fault report comprises common faults of the brake system and solutions thereof, wherein the common faults comprise poor transmission of a brake control device, faults of the brake control device, short lines of a speed generator of the brake control device, insufficient brake force, unreleasable brake, locking display of a monitoring display, incapability of resetting of emergency brake of a train, no electricity of control equipment such as a monitor and the like, low total wind pressure display of a pressure gauge and the like, and a maintenance worker carries a mobile PTU when needing to reset and confirm the equipment in the train, so that the state of the train can be observed in real time during fault processing.
