JP4825040B2 - Synthetic sleepers and train operation management system using the synthetic sleepers - Google Patents

Abstract

When it is determined that an engine speed NE rapidly decreases (positive outcome at S210), a throttle increase amount TAu and a valve lift increase amount VLu are computed based on a decrease rate NEd of the engine speed NE (S220). Then, a target throttle opening degree TAt of a throttle valve and a target maximum valve lift VLt of an intake valve are increased by using the throttle increase amount TAu and the valve lift increase amount VLu (S230). As a result, a drop in the engine speed during idling is reliably suppressed.

Description

  The present invention is used in railways such as iron-wheel-supported linear motor cars, and particularly relates to a railway sleeper for facilitating train operation management and a train operation management system using the synthetic sleeper.

  2. Description of the Related Art Conventionally, an IC chip is provided in a bearing component of a railway vehicle to prevent misassembly (see, for example, Patent Document 1).

  In such a case, for example, as shown in FIG. 8, an IC tag 2 for RFID (Radio Frequency Identification) is provided on a part of the front lid 1 as a bearing component used for supporting the axle. ing.

  This IC tag 2 can be both read and written from the outside using radio waves, and stores bearing specification information or various data such as inspection date and specification history.

  A resin cover member 3 is provided around the IC tag 2 and is configured to be fixed to the metal front lid 1 via the resin cover member 3.

  In the conventional IC tag 2 configured as described above, even when the front lid 1 to which the IC tag 2 is attached is made of metal, when microwaves are used to read various data, the microwave is applied to the front lid 1. Reading is possible without being absorbed.

These read data are collated with data read from other components and the like, thereby preventing erroneous assembly.
JP-A-63-186552 (paragraphs 0009 to 0024, FIGS. 1 and 8)

  However, in the conventional configuration configured as described above, since the IC tag 2 is fixed to the metal front lid 1 in the vicinity of the bearing portion of the train, a microwave is separately provided like the resin cover member 3. Therefore, there is a problem in that the number of parts increases.

  In addition, it has been difficult to ensure a desired mounting strength in the vicinity of a bearing portion of a train that is used outdoors for a long period of time.

  Furthermore, a train operation management system is also conceivable in which the data of the IC tag 2 provided on the train side is read by a reader provided on the track side and used as train operation data.

  However, in such a case, a certain weather resistance must be given to the reading device installed at each reading point, and there is a possibility that the structure becomes complicated.

  Accordingly, an object of the present invention is to provide a synthetic sleeper for railways that can easily obtain desired durability without increasing the number of parts separately, and a train operation management system using the synthetic sleeper.
