[0049] Figure 10 It is a schematic diagram showing the structure of a railway vehicle provided with the detection device according to the first embodiment. Figure 10 (A) shows the side view which looked at the railway vehicle 100 from the outer side of a vehicle. exist Figure 10 In (A), reference numeral 101 denotes an entrance and exit of a vehicle. There are many entrances and exits in the vehicle, but two entrances and exits are drawn in this figure. Movable doors 101-A and 101-B are provided at the respective entrances and exits 101 of the vehicle.

[0050] In the drawing, reference numeral 103 denotes a entrapment detection sensor installed on the side of the door 101-B, and reference numeral 104 denotes a entrapment detection sensor installed on the side of the door 101-A. Doors 101-A and 101-B pass along the Figure 10 Opening and closing are performed by moving in the direction indicated by arrow 101D in (A). When the doors 101-A and 101-B are closed, the entr...

[0127] Figure 9 It is a block diagram showing the configuration of the detection unit according to the second embodiment. In the second embodiment, when the diagnosis mode is designated, the voltage supplied to the electrode lines SNL1 and SNL2 changes with time. As a result, unless a disconnection occurs, the output voltages that change with time are supplied from the sensors SN1 to SN3 to the voltage detection circuit 2 . On the other hand, when a disconnection occurs, the output voltage supplied to the voltage detection circuit 2 becomes the second voltage V2 ( L2 ) which does not vary with time. Therefore, the voltage detection circuit 2 can determine whether or not a disconnection failure has occurred by determining whether or not the output voltages of the sensors SN1 to SN3 have changed over time.

[0128] Next, a more specific description will be given. To the voltage detection circuit 2 according to the second embodiment, a comparator circuit CMP and a voltage var...

Abstract

The present invention provides a technology capable of detecting a catch using a catch detecting sensor and also performing a diagnosis of the catch detecting sensor. A detector includes a catch detecting sensor provided with a detecting member, and a detecting unit connected to the catch detecting sensor. The detecting unit is configured to output a detection signal based on a result detected bythe catch detecting sensor when a detection mode is specified. Further, the detecting unit is configured to output a diagnostic signal based on a failure of the catch detecting sensor when a diagnostic mode is specified.

Description

technical field [0001] The present invention relates to a detection device, for example, to a detection device including a entrapment detection sensor and a detection unit provided on a vehicle. Background technique [0002] A technique related to a entrapment detection sensor installed in a vehicle such as an automobile is described in Patent Document 1, for example. Patent Document 1 describes an entrapment detection sensor including a tubular member having a plurality of electrode wires arranged apart from each other. When an object (hereinafter, including passengers, cargo, etc.) is caught, the tubular member is deformed in a crushed manner by an external force, and the electrode wires are brought into contact, whereby the detecting unit outputs a detection signal indicating the caught. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2014-216300 [0006] Since the entrapment detection sensor is install...
