  The train information storage unit 10 is a part that stores train information output by the train information input unit 9. The train information storage unit 10 is, for example, a memory that stores daily train information in chronological order. The date and time measuring unit 11 is a part that measures the current date and time. The date / time measuring unit 11 has, for example, a calendar function for measuring today's date and a clock function for measuring the current time, and outputs the measurement result to the control unit 12 as current date / time information (current date / time signal). To do.

  The control unit 12 is a part that controls various operations of the movable fence device 1. The control unit 12 controls the operation of the driving units 6A and 6B based on the approach of the train T to the home F and the advance of the train T from the home F. The control unit 12 refers to the train information storage unit 10 based on the train entry detection signal output from the train detection unit 7 and the current date / time signal output from the date / time measurement unit 11, and the train T entering the home F is the home Judge whether to stop at F. After the train T enters the home F, the control unit 12 starts moving the movable bodies 3A and 3B backward, and before the train T stops at the home F and the door D opens, the movable bodies 3A and 3B The drive units 6A and 6B are controlled to complete the backward movement. For example, the control unit 12 controls the operation of the drive units 6A and 6B so that the movable bodies 3A and 3B complete the backward operation when the traveling speed of the train T becomes a slow speed. Here, the slow speed is, for example, an operation speed of about 15 km / h at which the train T can be stopped immediately, and is defined by the railway operation rules. The control unit 12 determines whether or not the movable bodies 3A and 3B have completed the backward movement operation based on the movement amount detection signal output from the drive amount detection unit 6c.

Next, the operation of the movable fence device according to the first embodiment of the present invention will be described.
FIG. 6 is a flowchart for explaining the operation of the movable fence device according to the first embodiment of the present invention. FIG. 7 is a schematic view for explaining the operation of the movable fence device according to the first embodiment of the present invention. FIG. 7A is a side view showing a state immediately before entering the train, and FIG. ) Is a side view showing a state of entering the train, FIG. 7C is a side view showing a state immediately before the train stops, FIG. 7D is a side view showing a state immediately after the train stops, FIG. 7E is a side view showing a state after the train has advanced. Hereinafter, the operation of the control unit 12 will be mainly described.

In step (hereinafter referred to as S) 100 shown in FIG. 6, the control unit 12 determines whether or not the train T has entered the home F. As shown in FIG. 7A, when the train T enters the home F, the head of the vehicle V ₁ blocks the light beam between the light emitting unit 7a and the light receiving unit 7b of the train detecting unit 7 shown in FIG. The train detection unit 7 outputs a train approach detection signal to the control unit 12. When the train entry detection signal is input to the control unit 12, the control unit 12 determines that the train T has entered the home F and proceeds to S110. When the train entry detection signal is not input to the control unit 12, this train The control unit 12 repeats the determination until the entry detection signal is input to the control unit 12.

  In S110, the control unit 12 refers to the train information storage unit 10. When the control unit 12 determines that the train T has entered the home F, the train information storage unit 10 stores the current date / time signal output to the control unit 12 by the date / time measurement unit 11 illustrated in FIGS. 1 and 2. The control unit 12 refers to the train information.

In S120, the control unit 12 determines whether or not the train T stops at the home F. The control unit 12 refers to the train information storage unit 10 illustrated in FIGS. 1 and 2, and the control unit 12 determines whether the train T that has entered the home F stops at the home F. When the control unit 12 determines that the train T stops at the home F, the process proceeds to S130. On the other hand, when the control unit 12 determines that the train T is a passing train that passes through the platform F, the series of processes is terminated, and the boundary lines L _{1 to} L as shown in FIGS. 1 (A) and 2 (A). ₃ , the movable bodies 3 </ _b > A and ₃ </ _b > B are maintained in a dispersed state, and the entry blocking unit 4 prevents the passenger M from entering the track side area A ₁ from the home side area A ₂ .

In S130, the control unit 12 commands the driving units 6A and 6B to start the backward movement of the movable bodies 3A and 3B. When the train T stops at the platform F, it is necessary to permit passage between the track side area A ₁ and the platform side area A ₂ to allow passengers M to get on and off. Therefore, when the control unit 12 determines that the train T entering the home F stops at the home F, the driving force generating unit shown in FIG. 5A is configured so that the movable bodies 3A and 3B start the backward movement. In 6a, the control unit 12 commands the start of the backward movement. As a result, as shown in FIGS. 7 (A) and 7 (B), the movable bodies 3A and 3B between the fixed bodies 2A and 2B, which are areas where the train T enters first, start a backward movement, and then this train The movable bodies 3A and 3B between the fixed bodies 2B and 2C, which are areas where T enters, start to move backward, and finally the movable bodies 3A and 3B between the fixed bodies 2C and 2D which are areas where the train T enters Start the backward movement.

When the driving force generator 6a shown in FIG. 5A rotates the driving shaft 6g and the winding member 6f starts to move, the first movable bodies 3A ₁ and 3B ₁ shown in FIG. The retreat is started together with the member 6f. When the first movable bodies 3A ₁ and 3B ₁ are retracted from the position P ₃ , the entry blocking section 4 connecting the _first movable bodies 3A ₁ and 3B ₁ and the second movable bodies 3A ₂ and 3B ₂ relaxes. The first movable bodies 3A ₁ and 3B ₁ collide with the _second movable bodies 3A ₂ and 3B ₂ . As a result, the first movable bodies 3A ₁ and 3B ₁ and the second movable bodies 3A ₂ and 3B ₂ integrally collide with the _third movable bodies 3A ₃ and 3B ₃ , as shown in FIG. As shown in the figure, the movable bodies 3A and 3B are sequentially retracted toward the positions P ₁ and P ₂ while repeating the same operation.

At this time, as shown in FIGS. 7B and 7C, when the train T enters the platform F, the side surface of the train T functions as a protective wall, so that the platform F moves onto the track R. The fall of the passenger M is prevented. As shown in FIG. 7C, when the train T is about to stop at the home F, the speed of the train T decreases to a slow speed (for example, about 15 km / h). For this reason, even if the passenger M falls from the home F and the situation where the train T is stopped in an emergency occurs, the train T stops immediately if the driver of the train T operates the brake device. Further, when the speed of the train T that has entered the platform F decreases to the slow speed, the safety of the passenger M is not impaired even if the track side area A ₁ is completely opened. In general, the speed at which the train T enters the home F is a substantially constant speed, and the distance from the end on the approach side of the home F to the stop position target of the train T is a constant distance, so the train T enters the home F. After that, the time during which the speed of the train T decreases to the slow speed also becomes a substantially constant time. For this reason, the control part 12 is made so that all the movable bodies 3A and 3B complete reverse operation | movement in the substantially fixed time after the train T approachs the platform F until the speed of this train T falls to a slow speed. The drive units 6A and 6B are driven and controlled.

In S140, when the traveling speed of the train T becomes the slow speed, the control unit 12 determines whether or not the movable bodies 3A and 3B have moved backward to the positions P ₁ and P ₂ shown in FIG. When the driving force generator 6a shown in FIG. 5A rotates the rotating body 6d, the driving amount detection unit 6c detects the amount of rotation of the rotating body 6d (the amount of movement of the movable bodies 3A and 3B), and a driving amount detection signal. Is output to the control unit 12. The amount of movement of the _first movable bodies 3A ₁ and 3B ₁ from the position P ₃ shown in FIG. 3A to the positions P ₁ and P ₂ shown in FIG. 3C is constant. For this reason, the control unit 12 calculates the movement amounts of the _first movable bodies 3A ₁ and 3B ₁ based on the drive amount detection signal output from the drive amount detection unit 6c shown in FIG. The control unit 12 determines whether or not the bodies 3A ₁ and 3B ₁ have moved back to the positions P ₁ and P ₂ . When the control unit 12 determines that the movable bodies 3A and 3B have moved back to the positions P ₁ and P ₂ , the control unit 12 determines that the movable bodies 3A and 3B have not moved back to the positions P ₁ and P _2. were the case, the control unit 12 to the movable body 3A, 3B are retracted to the position P _1, P ₂ is repeated determination.

In S150, the control unit 12 commands the drive units 6A and 6B to end the backward movement of the movable bodies 3A and 3B. Based on the drive amount detection signal output by the drive amount detector 6c shown in FIG. 5A, the first movable bodies 3A ₁ and 3B ₁ move backward to the positions P ₁ and P _{2 of} the boundary lines L _{1 to} L _3. When the control unit 12 determines that the operation has been performed, the control unit 12 instructs the driving force generation unit 6a of the driving units 6A and 6B to end the reverse operation. As a result, the driving force generator 6a stops the rotation of the driving shaft 6g, and the movable bodies 3A and 3B are gathered at the positions P ₁ and P ₂ as shown in FIG. 3C, as shown in FIG. track-side area A ₁ is opened so. After that, as shown in FIG. 2B, when the train T stops at a predetermined stop position target of the home F and the conductor operates the conductor switch to open the door D, the track side area A ₁ and the home are allowed passage between the side regions a ₂ and the passenger M can get on and off.

In S160, the control unit 12 determines whether or not the train T has advanced from the home F. As shown in FIG. 2 (B), when the train T stops at the home F, opens the door D, and the passenger M completes getting on and off, the conductor operates the conductor switch to close the door D, and the train T Depart from F. When the train T moves forward from the home F, it intercepts the leading portion of the vehicle V ₁ of the light beam between the light emitting portion 8a of the train detector 8 shown in FIG. 1 and the light receiving portion 8b, train control unit 12 the train detector 8 An advance detection signal is output. When the train advance detection signal is input to the control unit 12, the control unit 12 determines that the train T has advanced from the home F and proceeds to S170. When the train advance detection signal is not input to the control unit 12, this train The control unit 12 repeats the determination until the advance detection signal is input to the control unit 12.

  In S170, the control unit 12 determines whether or not a predetermined time has elapsed. Based on the train advance detection signal output by the train detection unit 8 shown in FIGS. 1 and 2 and the current date / time signal output by the date / time measurement unit 11, a predetermined time has elapsed since the train T left the home F. Whether or not the control unit 12 determines. When the control unit 12 determines that the predetermined time has elapsed since the train T departed from the home F, the process proceeds to S180, and when the predetermined time has not elapsed since the train T departed from the home F, the predetermined time elapses. Until the control unit 12 repeats the determination.

In S180, the control unit 12 commands the drive units 6A and 6B to start the advance operation of the movable bodies 3A and 3B. When the train T departs from the home F, it is necessary to restrict the traffic between the track side area A ₁ and the home side area A ₂ and prevent the passenger M from falling on the track R from the home F. There is. Therefore, when the control unit 12 determines that the train T has advanced from the home F and a predetermined time has elapsed, the advance operation is sequentially started from the _first movable bodies 3A ₁ and 3B ₁ shown in FIG. In addition, the control unit 12 instructs the driving force generation unit 6a shown in FIG. As a result, the driving force generator 6a rotates the driving shaft 6g in the reverse direction, and the winding member 6f starts moving in the reverse direction, and the first movable bodies 3A ₁ and 3B ₁ advance together with the winding member 6f. To start. As shown in FIG. 4B, when the first movable bodies 3A ₁ and 3B ₁ advance from the positions P ₁ and P ₂ , the first movable bodies 3A ₁ and 3B ₁ and the second movable body 3A ₂ are moved. , 3B ₂ , the entry blocking section 4 is in tension, and the second blocking bodies 3A ₂ , 3B ₂ are pulled by the entry blocking section 4. When the first movable bodies 3A ₁ , 3B ₁ and the second movable bodies 3A ₂ , 3B ₂ advance at an interval, the second movable bodies 3A ₂ , 3B ₂ and the third movable bodies 3A ₃ , 3B ₃ The entry preventing part 4 connecting the two becomes tensioned, and the third movable bodies 3A ₃ and 3B ₃ are pulled by the entry preventing part 4. Similar operations repeating while movable member 3A toward the position P _3, 3B is advanced successively.

In S190, FIG. 4 the control unit 12 whether the movable body 3A, 3B is advanced to a position P ₃ shown in (C) to determine. When the driving force generator 6a shown in FIG. 5A reverses the rotating body 6d, the driving amount detector 6c detects the amount of rotation of the rotating body 6d (the amount of movement of the movable bodies 3A and 3B), and a driving amount detection signal. Is output to the control unit 12. The amount of movement of the _first movable bodies 3A ₁ and 3B ₁ from the positions P ₁ and P ₂ shown in FIG. 4A to the position P ₃ shown in FIG. 4C is constant. Therefore, the control unit 12 calculates the movement amounts of the _first movable bodies 3A ₁ and 3B ₁ based on the drive amount detection signal output from the drive amount detection unit 6c shown in FIG. The control unit 12 determines whether or not 3B has advanced to the position P ₃ . Proceeds to S200 when the movable body 3A, a control unit 12 3B is advanced to the position P ₃ is determined, when the movable body 3A, 3B position P ₃ control unit 12 has not been advanced to determines the movable body 3A , 3B repeats the determination until it advances to position P ₃ .

In S200, the control unit 12 commands the drive units 6A and 6B to end the advance operation of the movable bodies 3A and 3B. Based on the drive amount detection signal output by the drive amount detection unit 6c shown in FIG. 5A, control is performed so that the _first movable bodies 3A ₁ and 3B ₁ advance to the position P _{3 of} the boundary lines L _{1 to} L _3. When the unit 12 determines, the control unit 12 instructs the driving force generating unit 6a to end the advance operation. As a result, when the driving force generator 6a stops the reverse rotation of the driving shaft 6g and the first movable bodies 3A ₁ and 3B ₁ are joined at the position P ₃ as shown in FIG. 4C, FIG. ) and 2 (boundary line as shown in a) L ₁ ~L ₃ on the movable body 3A, the track-side area a ₁ 3B is dispersed is closed. For this reason, the passage between the track side area A ₁ and the platform side area A ₂ is restricted, and the passenger M is prevented from falling from the platform F onto the track R.
