Description

  The present invention relates to a release control method and a system for preventing an accident such as contact destruction caused by a vehicle passing through a gate bar that controls passage / stop of a vehicle on a toll road, for example.

Conventionally, for example, an ETC system has been adopted in a toll road such as an expressway, and an ETC-equipped vehicle can pay a toll by wireless communication, in which case the gate bar of the gate device remains open, Can pass without stopping.
For some reason, for example, when wireless communication is not possible between the vehicle-mounted device and the toll gate, the gate bar will not open. The driver of the vehicle believes that his vehicle is equipped with ETC and can pass through the gate device unconditionally.
In order to reduce the impact with the gate bar at this time, the general bar release method currently performed is that when the horizontal force generated when the vehicle contacts the gate bar exceeds the specified value, It was a method that deviated from the rotation axis. For this reason, when releasing, the gate bar and the vehicle always come into contact with each other, and when the traveling speed of the vehicle is high, the gate bar and the gate device for driving and controlling the gate bar may be damaged.

  The problem to be solved is to prevent accidents due to contact without causing contact between the vehicle and the gate bar.

The sensor is composed of an optical sensor arranged on both sides of the vehicle passage and a loop coil sensor arranged on the vehicle passage, the vehicle detection sensor detects a vehicle traveling from the vehicle detection sensor to the gate device, and the vehicle detection sensor The gate bar is opened in the vehicle traveling direction when the gate device does not open the gate bar upward while the vehicle is being detected .

The gate bar release control method according to claim 2 is the method according to claim 1, wherein the gate bar is advanced by releasing the prevention of rotation in the direction perpendicular to the drive shaft for the vertical opening and closing drive of the gate bar by explosive explosion. It is characterized by opening in the direction.

The gate bar release control system according to claim 3 is a gate bar control system in which a vehicle detection sensor is disposed in front of the gate device in the vehicle traveling direction, and the gate bar is moved up and down to control passage / stop of the vehicle. A vehicle detection sensor comprising a light sensor disposed on both sides of a road and a loop coil sensor disposed on a vehicle traffic path, the vehicle detection sensor detecting a vehicle traveling from the vehicle detection sensor toward the gate device, and the vehicle detection sensor And a gate bar opening mechanism that opens the gate bar in the vehicle traveling direction when the gate device does not open the gate bar upward while the vehicle is being detected .

A gate bar release control system according to a fourth aspect of the present invention is the gate bar release mechanism according to the third aspect, wherein the gate bar opening mechanism is provided so that the gate bar can be rotated in a direction perpendicular to a driving shaft for driving the gate bar to be opened and closed vertically. A rotation prevention mechanism that supports the rotation shaft and prevents the gate bar from rotating around the opening rotation shaft is released. The rotation prevention mechanism is released by explosive explosion, and the gate bar is rotated around the opening rotation shaft to open in the traveling direction. It is characterized by doing.

  According to the gate bar release control method of the first aspect, when a vehicle entering when the gate bar is closed is detected, the gate bar is opened in the vehicle traveling direction before the vehicle contacts the gate bar. Since it is removed from the gate device, accidents due to contact such as vehicle damage due to contact with the gate bar can be prevented in advance. The gate bar and the gate device itself can be used again.

  According to the gate bar release control method according to claim 2, the gate bar is released in the traveling direction by releasing the rotation prevention in the vertical direction with respect to the drive shaft for opening and closing the gate bar by exploding the explosive, so that the gate bar can be released at high speed. it can.

  According to the gate bar release control system of the third aspect, when the vehicle detection sensor detects a vehicle entering when the gate bar is closed, the gate opening mechanism moves the gate bar to the vehicle before the vehicle contacts the gate bar. Since the gate bar is removed from the gate device by opening in the traveling direction, accidents due to contact can be prevented in advance. And it can prevent that a vehicle is damaged by the contact with a gate bar.

  According to the gate bar release control system of the fourth aspect, the gate bar is supported on the open rotary shaft so as to be rotatable in the drive shaft direction for opening and closing the gate bar, and the gate bar is prevented from rotating around the open rotary shaft. The rotation prevention mechanism is released by explosive explosion, and the gate is rotated around the opening rotation axis to open in the traveling direction, so that it can be released at high speed.

FIG. 1 is a diagram for explaining the operation of a system according to the present invention. FIG. 1 (a) illustrates vehicle approach, FIG. 1 (b) illustrates vehicle detection / bar release, and FIG. 1 (c) illustrates vehicle passing. FIG. FIG. 2 is a flowchart. In FIG. 1, 101 is a roadside device, 102 is an antenna that constitutes the roadside device 101 and transmits and receives radio waves for radio communication between antennas provided in a vehicle, which will be described later, and 103 is a lane control device that constitutes the roadside device 101. , 104 is a gate control device, 105 is a vehicle, 106 is a vehicle passage, 107 is a light sensor installed on each side of the vehicle passage 106, 108 is a loop coil sensor provided under the vehicle passage 106, 109 is a gate Device.
The lane control device 103 converts the signal to the antenna 102 and the signal from the antenna 102 into a signal to the gate control device 104. The optical sensor 107 and the loop coil sensor 108 are arranged in front of the gate device 109 in the traveling direction of the vehicle so that the vehicle can be detected almost simultaneously.
The gate device 109 is shown in FIG. In FIG. 3, 1091 is a drive unit, 1092 is a drive shaft, 1093 is a case, 1094 is a gate bar, 1095 is provided perpendicular to the upper surface of the case 1093, and the gate bar 1094 is rotated in a direction perpendicular to the drive shaft 1092 in the case 1093. An open rotation shaft 1096 that can be supported is a rotation blocking mechanism interposed between the case 1093 and the gate bar 1094.
The gate bar 1094 moves up and down by the rotation of the drive shaft 1092 rotated by the opening / closing drive control of the drive unit 1091, and opens and closes the gate through the case 1093. At this time, the gate bar 1094 is rotatably supported by an open rotation shaft 1095 provided in the case 1093, and a rotation prevention mechanism 1096 is provided between the case 1093 and the gate bar 1094 to prevent this rotation.

  When the vehicle 105 passes through the vehicle passage 106, the lane control device 103 determines whether or not the vehicle can pass through communication with the antenna 102 (P201). If it is determined that the vehicle 105 is allowed to pass, the gate bar is opened (P202). The vehicle 105 further proceeds. On the other hand, if the lane control device 103 determines that traffic is impossible, the gate bar is not opened. The traveling vehicle 105 is detected by the optical sensor 107 (P203), and is determined to be ON. Further, the vehicle 105 is sensed by the loop coil sensor 108 (P204), and is determined to be ON. At this time, when the gate bar is opened at P202, the vehicle passes through the gate bar with the gate bar opened at P205 (P206), and then the gate bar is closed (P207). On the other hand, when the gate bar is closed in P202, the gate bar is closed in P205, and in P206, when the optical sensor is ON (P203) and the loop coil sensor is ON (P204), the release ignition, that is, the anti-rotation mechanism 1096 is charged. Explode (P208).
