[0015]
FIG. 3 is a block diagram showing an electrical configuration of the reverse running vehicle stop device according to the present invention. That is, this reverse running vehicle stop position is omitted in FIG. 2A, but is formed around a CPU that performs predetermined arithmetic processing using the system program and working data stored in the memory 10. The controller 11 is responsible for the first and second stop control means of the present invention.
[0016]
This controller (CPU) 11 includes, via an I / O unit 12, a sensor amplifier 13 that processes detection signals from the sensors S 1, S 2, S 3, and S 4, and a circuit breaker driver 14 that controls the circuit breakers 1 and 2. A display driver 15 for driving and controlling the display content of the display board 5, an audio driver 16 for driving and controlling the sound of the speakers 3 and 4, and an image processing unit 17 for processing image data of the video camera 6. Yes.
[0017]
Hereinafter, the vehicle detection control operation in one block section of the reverse running vehicle stop device having the above configuration will be described with reference to the time charts of FIGS. 4 and 5.
[0018]
When a vehicle a traveling in the forward direction reaches the sensor S1, detection of the vehicle a is disclosed by the sensor S1, and a detection signal corresponding to the vehicle length and vehicle speed of the vehicle a is obtained (FIG. (Refer to S1 of 4). Then, after the detection of the sensor S1, a detection signal similar to that of the sensor S1 is obtained also in the sensor S2 after a predetermined time corresponding to the vehicle speed of the vehicle (see S2 in FIG. 4).
[0019]
Although it is possible to detect the vehicle only by the detection signal of the sensor S1, the sensor S1 may start detection by some object, so the sensor S1 starts the detection and the sensor S2 ends the detection. the sensors S1, S2 vehicle Lee in clogging the interval by aND condition of is arranged to determine that it has entered (see entry car determination and vehicle judgment under 4 of S1, S2).
[0020]
When the vehicle a travels in the forward direction in the closed section, detection is started by the sensors S3 and S4 after a while. The sensors S3 and S4 are detected in the same manner as the sensors S1 and S2, and the advance of the vehicle A from the closed section is determined (indicated by S1 and S2 in FIG. 4 and the input under the S1 and S2). (See car judgment and vehicle judgment).
[0021]
The entry / exit state of the vehicle in the block section based on the detection signals of the above-described sensors S1, S2, S3, S4 is stored in the memory 10 of the controller 11, and later for grasping the traveling state of the vehicle on the one-way R. It is said that.
[0022]
FIG. 5 is a time chart in a state where the vehicles A and A 'pass through the sensors S1 and S2 in a continuous state. As described above, when the vehicles A and B 'are in a continuous state, the entry determination that turns ON (high) by the detection signal of the sensor S1 and turns OFF (low) when the detection of the sensor S2 is completed. 'Is included, and the entry of the vehicles A and A' into the closed section is detected according to the rising conditions of the sensors S1 and S2 within this range. The time chart of this figure does not show the time chart of the sensors S3 and S4 on the outlet side of the closed section, but the same detection as that of the sensors S1 and S2 on the inlet side of the closed section is performed. Therefore, the controller 11 determines that the vehicles A and B ′ have advanced from the closed section when the vehicle determination corresponding to the detection on the inlet side of the closed section is performed on the outlet side of the closed section.
[0023]
Next, the control operation at the time of reverse running vehicle generation will be described using the time charts of FIG. 2 (b) and FIG. In the time chart of FIG. 6, the vehicle a traveling in the forward direction is the same as the upper part of the time chart of FIG.
[0024]
As shown in FIG. 2 (b), when the vehicle B enters the one-way path R in the reverse direction, detection of the vehicle B is first started by the sensor S4 (see the sensor S4 in FIG. 6), and then the sensor Detection is started by S3 (see sensor S3 in FIG. 6). The controller 11 detects the sensor S4 earlier than the sensor S3, and between the detection start of the sensor S4 and the detection end of the sensor S3 (see vehicle entry determination in FIG. 6), depending on the AND conditions of the sensors S3 and S4. It is determined that a reverse running vehicle has occurred (see vehicle determination in FIG. 6). Then, the controller 11 lowers (closes) the arms 1a and 2a of the circuit breakers 1 and 2 through the circuit breaker driver 14, and displays the display contents on the display board 5 through the display driver 15 in the forward direction. The driver is alerted by blinking the contents of the warning to stop because an abnormal situation ahead (occurrence of reverse running vehicle) has occurred, and the speakers 3 and 4 via the voice driver 16 The driver of both vehicles A and B is warned by voice to stop the vehicle. At the same time, the image processing unit 17 analyzes the image data input via the video camera 6 and identifies the vehicle b.
[0025]
As described above, since the vehicle B traveling backward on the one-way path R is prevented from proceeding further by the closing of the circuit breaker 1, a serious accident in which the vehicle B collides with the vehicle B in the forward direction. Can be prevented in advance. Further, the warning from the speaker 3 allows the vehicle driver to know that he / she has run backward on the one-way street R.
[0026]
Furthermore, the vehicle B that has violated the travel is captured between the pair of circuit breakers 1 and 2, and is specified through the video camera 6, whereby the subsequent predetermined measures can be efficiently performed. .
[0027]
Further, the driver of the vehicle a in the forward direction knows in advance that there is a reverse running vehicle (b) ahead by the speaker 4 and the display board 5 and further by the shut-off device 1 being closed. Therefore, safety measures can be taken in advance.
[0028]
