Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle condition monitoring system.
[0002]
[Prior art]
A conventional vehicle state monitoring system will be described in detail with reference to the drawings. FIG. 2 is a configuration diagram of a conventional vehicle state monitoring system.
In the conventional vehicle state monitoring system, the state of the devices and devices mounted on the vehicle 1 is displayed on the vehicle monitor device 2 that displays the device state of the vehicle, and is constantly monitored by the crew. The details of the state of the on-vehicle equipment are recorded on the data storage medium 3, and after the operation is completed, the record is called from the data storage medium 3 at a garage inspection place or the like to know the state and status of the equipment. From the failure information of the equipment read out from the data storage medium 3, the inspection / repair is informed to the parts maker and the repair is performed.

Japanese Patent Laid-Open No. 10-76952 [Problems to be Solved by the Invention]
However, since only the crew members know the status of the equipment while the railway vehicle is in operation, if a malfunction occurs, the crew must notify the appropriate department of the situation, ask for a decision, and decide whether to continue or stop driving. I had to. Also, since detailed information on the condition of the equipment can only be obtained after the end of operation (after entering the garage), repair work will be carried out later, especially if parts replacement is necessary, there will be stock on-site. However, if there is no stock, it is necessary to contact the parts manufacturer and request technical dispatch depending on the contents of repair.
If the parts stock is always available, the replacement can be done immediately. However, if there are many parts stock, the location, unnecessary assets, and management costs will increase, which will be a heavy burden on the operator. For manufacturers, shortening the time required to receive replacement parts and delivering them to business operators and securing personnel are issues.
Accordingly, an object of the present invention is to provide a vehicle state monitoring system that can quickly grasp the state of a device mounted on a vehicle.
[0004]
[Means for Solving the Problems]
The above-mentioned problems are mounted on a railway vehicle, the vehicle monitor device that acquires the device information of the rail vehicle and the position information of the previous rail vehicle, the device information of the rail vehicle acquired by the vehicle monitor device, and the position of the rail vehicle An in-vehicle communication device for transmitting information; and a monitoring center that receives device failure information and railroad vehicle position information from the in-vehicle communication device via a wireless communication network, and the monitoring center includes the in-vehicle communication device This can be achieved by analyzing the failure information of the equipment received from 1 and selecting a server to transmit the failure information.

DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
A vehicle state monitoring system according to a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a vehicle state monitoring system according to a first embodiment of the present invention. 2 that are structurally the same as those described in FIG. 2 are denoted by the same reference numerals and description thereof is omitted.
The vehicle state monitoring system according to the first embodiment of the present invention includes an in-vehicle communication device 6 for sending vehicle monitor information to the ground side, a control device (not shown) for connecting the in-vehicle device and the vehicle monitor device, a vehicle, It is mainly composed of a radio communication network 7 connecting the ground, a monitoring monitor center 8 on the ground side, a server 9, a position information device 10, a GPS antenna 11, a GPS satellite 12, and the like.
The vehicle state monitoring system configured as described above acquires position information with the GPS antenna 11, converts the data with the position information device 10 (GPS in-vehicle device) in the vehicle monitor device 2, and converts the in-vehicle antenna from the in-vehicle communication device 6. The data including the failure information is transmitted to the monitoring center 8 via the wireless communication network 7 using the public network (packet communication). The monitoring center 8 centrally monitors device failure information and position information. Therefore, the monitoring center 8 can grasp the state of the vehicle while staying there. The monitoring center 8 discriminates the importance of the abnormality of these pieces of information (failure importance and position information), and according to the importance, which server 9 is provided in the business operator, the inspection place, the vehicle manufacturer, and the parts manufacturer. Determine whether to send information. Therefore, it becomes possible to instruct information to an appropriate server 9, and a quick response can be made.
[0006]
In the vehicle state monitoring system configured as described above, the monitoring center 8 constantly receives the device information and determines the importance of the device abnormality, so that it is possible to reduce the contact and request work to each component manufacturer. Eliminates the need for extra parts and parts, thus reducing costs.
The vehicle state monitoring system configured as described above can quickly grasp the state of equipment mounted on the vehicle.
[0007]
【The invention's effect】
According to the present invention, it is possible to provide a vehicle state monitoring system that can quickly grasp the state of a device mounted on a vehicle.
