When the electromagnetic element 44 is de-energized, the push rod 441 of the electromagnetic element 44 retracts to drive the double-sided rack 43 to move in the direction opposite to the direction D, so that the guardrail 100 is in the first working state as shown in fig. 2 and 3.

In other embodiments of the present disclosure, a linear motor, for example, may be employed as the motive member instead of the electromagnetic member 44. During installation, the abutting part can be arranged on the double-sided rack 43, and the end part of the telescopic shaft of the linear motor is connected with the abutting part, so that the telescopic shaft of the linear motor drives the double-sided rack 43 to move in the telescopic process.

In addition, in other embodiments of the present disclosure, the electrically controlled driving device may also be a commercially available door opening machine, which drives the relative rotation of the first door body 10 and the second door body 20 by mounting the door opening machine on the base 30.

As shown in fig. 2 and 6, in an embodiment of the present disclosure, the electrically controlled driving device may further include an elastic restoring member 45, one end of the elastic restoring member 45 is connected to the other end of the double-sided rack 43, and the other end of the elastic restoring member 45 is connected to the base 30, for applying a restoring force to the double-sided rack 43 to move it in a direction opposite to the direction D.

Accordingly, when the power supply to the electromagnetic member 44 is cut off when the guardrail 100 is in the second state, the push rod 441 of the electromagnetic member 44 can be moved in the direction opposite to the direction D by the restoring force of the elastic restoring member 45. By providing the elastic restoring member 45, the reliability of the retracting action of the push rod 441 is increased.

Optionally, in one embodiment of the present disclosure, the elastic restoring member 45 is a spring. As shown in fig. 2, a stopping protrusion 432 extending downward is formed on the double-sided rack 43, a protruding pillar 433 is formed on the stopping protrusion 432, one end of the spring is sleeved on the guiding pillar 31 of the base 30, and the other end of the spring is sleeved on the protruding pillar 433. As shown in fig. 6, when the double-sided rack 43 is moved in the direction D such that the guardrail 100 is in the second operating condition, the resilient return member 456 is in a compressed state. Therefore, when the electromagnetic member 44 is de-energized, the double-sided rack 43 is ensured to move in the direction opposite to the direction D to the position where the guard rail 100 is in the first working state by the restoring force of the elastic restoring member 45.

In other embodiments, the elastic restoring member 45 may be a spring sheet or made of other elastic materials.

As shown in fig. 2 and 7, in an embodiment of the present disclosure, the electrically controlled driving device may further include an electrically controlled locking member 46, and the electrically controlled locking member 46 is used for locking the position of the double-sided rack 43 when the guardrail 100 is in the second working state. Thus, when the electrically controlled locking member 46 locks the double-sided rack 43, even if the restoring force of the elastic restoring member 45 exists, the guardrail 100 can ensure that the guardrail 100 is kept in the second working state, and the independent channel 400 is kept closed. Moreover, the electric control locking piece 46 is operated in an electric control mode, so that the locking and unlocking of the electric control locking piece 46 can be controlled remotely and timely.

The present disclosure does not limit the specific structure of the guard rail 100. Alternatively, as shown in fig. 2, in an embodiment of the present disclosure, an electrically controlled locking member 46 is disposed below the double-sided rack 43, a locking pin 461 of the electrically controlled locking member 46 extends and retracts in a vertical direction, a locking hole (not shown) for engaging with the locking pin 461 is disposed on the push rod 441 of the electromagnetic member 44, and the locking pin 461 is configured to extend upward to be inserted into the locking hole when power is supplied and retract downward to be withdrawn from the locking hole when power is not supplied.

The power to the guardrail 100 can be cut off in case of an emergency or power failure. After power failure, the locking pin 461 of the electrically controlled locking member 46 is quickly disengaged from the push rod 441 of the electromagnetic member 44 due to the downward force generated when the elastic restoring member drives the double-sided rack 43 to move under the action of the dead weight. Thus, the double-sided rack 43 is moved in the direction opposite to the direction D by the elastic force of the elastic restoring member. Thereby driving the first gear 41 and the second gear 42 to rotate, and driving the door body to return to the state (the first working state) as shown in fig. 3 and 8, so that a large number of people can escape quickly.

Here, the electrically controlled locking member 46 may be an electromagnet, and the locking pin 461 is an iron core of the electromagnet. After power is lost, as shown in fig. 2, the iron core of the electromagnet will be separated from the push rod 441 of the electromagnetic element 44 under the action of the self weight of the iron core and the elastic reset element.

In other embodiments, the electrically controlled locking member 46 may directly lock the double-sided rack 43.

In one embodiment of the present disclosure, a position sensor is disposed on the guardrail 100 to detect the position of the double-sided rack 43 in the moving direction thereof, i.e., the position in the direction D, so as to accurately determine the state of the guardrail 100 and ensure that the guardrail 100 is in the correct state. For remote control, it is important to ensure the exact position of the guardrail 100.

The present disclosure is not limited to a particular number, type, and configuration of position sensors. Alternatively, as shown in fig. 4 and 6, in one embodiment of the present disclosure, the position sensor is an infrared sensor, and includes a first infrared sensor 51 and a second infrared sensor 52 arranged at intervals in the D direction.

The positions of the first infrared sensor 51 and the second infrared sensor 52 are configured such that, when the guard rail 100 is in the first working state, the first infrared sensor 51 is shielded and the second infrared sensor 52 is not shielded, see fig. 4; when the guardrail 100 is in the second working state, the first infrared sensor 51 is not shielded, and the second infrared sensor 52 is shielded.

To ensure proper operation of the guardrail 100. After the installation is completed, the guardrail 100 can be subjected to one-time self-checking operation, the guardrail 100 is switched from the first working state to the second working state, namely, the two door bodies are unfolded from the folding state and then return to the folding state. In this process, whether the blocking condition of the first infrared sensor 51 and the second infrared sensor 52 is correct is monitored. And detects whether the locking pin 461 of the electrically controlled locking member 46 can be normally extended to lock the push rod 441 of the electromagnetic member 44.

According to another aspect of the present disclosure, there is provided a diversion evacuation system comprising a plurality of the hobby horse guardrail sets 300 and the guardrail 100 described above, wherein when N is greater than 2, a plurality of the hobby horse guardrail sets 300 define N side by side independent channels 400, N-1 ones of the hobby horse guardrail sets 300 located at intermediate positions are respectively provided with one guardrail 100 at end positions in different directions (inlet side and outlet side) of two adjacent hobby horse guardrail sets 300, and when N is equal to 2, an end position of at least one end of the hobby horse guardrail set 300 located at an intermediate position is provided with one guardrail 100.

When the plurality of guardrails 100 are in the first operating state, the first door 10 and the second door 20 are used as a common rail to merge into the rail group 300, and the independent channel 400 between two adjacent rail groups 300 is maintained.

When the plural guardrails 100 are all in the second working state, the plural guardrails 100 and the plural metro guardrail 310 transform the N independent channels 400 into one diversion channel 500.

As can be seen from the above, by disposing the guardrail 100 at the position corresponding to the inlet side or the outlet side of the iron horse guardrail 310, the guardrail 100 can be switched between the first working state and the second working state according to the amount of the human flow, so as to well play a role in guiding the human flow and avoid the danger of crowding and treading.

In the present disclosure, the number of the set of iron horse guard rails 300 and the number of the independent channels 400 are not limited, and alternatively, the number N of the independent channels 400 may be any suitable number such as 2, 3, 4, and the like. In addition, the number of the metro guardrails 310 in each metro guardrail group 300 is not limited in the present disclosure, and an appropriate number may be selected as needed, specifically based on the people flow rate of the site and the space size of the site.

Optionally, as shown in fig. 10, in an embodiment of the present disclosure, the guided evacuation system further includes a control unit 200, and the control unit 200 is electrically connected to the electrically controlled driving device of the guardrail 100 to control the guardrail 100 to switch between the first operating state and the second operating state. That is, in the embodiment shown in fig. 10, the control unit 200 may be electrically connected to the electrically controlled driving means (including the electromagnetic member 44) to control the energization and de-energization of the electromagnetic member 44 and the electrically controlled locking member 46.

Alternatively, as shown in fig. 10, in one embodiment of the present disclosure, the control unit 200 may include a first processor 210, a switch 230, and a terminal 240, the first processor 210 or the terminal 240 is communicatively connected to the guardrail 100 through the switch 230, and the first processor 210 or the terminal 240 is communicatively connected to a fire alarm system FAS, a broadcast system PA, or a CCTV.

In this way, the first processor 210 may control the operation of the electrically controlled driving device according to a signal (such as a fire alarm signal or other type of alarm signal) transmitted by the fire alarm system FAS or the broadcast system PA system, or may control the operation of the electrically controlled driving device according to an instruction sent by an operator through the terminal 240 or an instruction preset by the terminal 240 itself. Further, the operator can set the operation mode of the guardrail 100 at the terminal 240 and also remotely operate the guardrail 100 to change the state of the guardrail 100. In addition to this. The first processor 210 can also be managed (e.g., set up programs, etc.) and monitored. The remote control of the diversion evacuation system is facilitated, and the system can work according to a set mode.

For example, the operator may set the mode of the system on the terminal 240. For example, the peak time can be set to be an early peak time at 7: 00-9: 00, and the peak time can be set to be a late peak time at 17: 00-19: 00. And may save this setting to the first processor 210. Here, the first processor 210 can provide a carrier for the system software to run, receive the operation instruction of the staff member on the terminal 240, and issue the instruction to the guardrail 100. Meanwhile, the operation records of the operator can be stored and the equipment state of the whole system can be monitored. In addition, the first processor 210 is communicatively connected to the fire alarm system FAS or the broadcasting system PA so as to be able to control the electromagnetic element 44 and the electrically controlled locking element 46 in conjunction when a specific event occurs, for example, when the first processor 210 detects that the fire alarm system FAS has issued a fire alarm, thereby switching the guardrail 100 from the second operation state to the first operation state.

Switch 230 may provide a path for network interworking. The network structure is variable, and a looped network, a star network or a special transmission network can be selected according to the field situation, which is not limited by the disclosure.

The terminal 240 (e.g., a workstation) may provide a human-computer interaction interface. The staff can set up the mode of operation of guardrail 100 on the workstation, also can remote operation guardrail 100 simultaneously, changes guardrail 100 state to carry out equipment management and control.

Optionally, as shown in fig. 10, in an embodiment of the present disclosure, the control unit 200 further includes a second processor 220, the second processor 220 is communicatively connected with the switch 230 and the electrically controlled driving device of the guard rail 100, respectively, and the second processor 220 is communicatively connected with the fire alarm system FAS or the broadcasting system PA.

Since the second processor 220 is provided to be connected in communication with the fire alarm system FAS or the broadcasting system PA, for example, to form a local area network connection with the fire alarm system FAS or the broadcasting system PA. Thus, for example, when the second processor 220 fails to communicate with the first processor 210 or the terminal 240 (e.g., a network failure occurs), the second processor 220 can also receive the fire alarm system FAS or the broadcast system PA signal, which can serve the purpose of redundant security.

Alternatively, in one embodiment of the present disclosure, the second processor 220 may include a relay, and the second processor 220 may execute a control signal of the terminal 240, the first processor 210, the fire alarm system FAS or the broadcasting system PA to change a closed or open state of the relay to turn on or off the power supply of the electromagnetic member 44 and the electrically controlled locking member 46, thereby implementing the control of the guardrail 100.

Alternatively, the second processor 220 may have an RJ45 interface and an RS232 interface, and be connected to the switch 230 through an RJ45, controlled by the first processor 210 or the terminal 240, and may also be connected to a fire alarm system FAS or a broadcast system PA through an RS232 interface.

In other embodiments, the relay may be provided separately, without being integrated within the second processor 220, such as being integrated onto the guardrail 100.

Optionally, in an embodiment of the present disclosure, as shown in fig. 10, the guided evacuation system further comprises an alarm 250, and the alarm 250 is communicatively connected to the control unit 200. Before the state of the guardrail 100 is changed, the alarm 250 can be controlled by the control unit 200 to start alarming, so as to achieve the purpose of reminding.

The present disclosure is not limited to a particular type of alarm 250, and alternatively, the alarm 250 may be an audible and visual alarm 250.

Alternatively, the audible and visual alarm 250 may be positioned directly above the guardrail 100 to sound an audible and visual alarm before the guardrail 100 is positionally adjusted to alert personnel to take care of the guardrail 100.

Optionally, in the present disclosure, the diversion evacuation system further includes a distribution box (not shown), the distribution box may be a device having fire-fighting linkage and not using fire-fighting electricity, and when the fire alarm system FAS needs and does not use fire-fighting electricity, the distribution box will cut off the electricity of the diversion evacuation system.

It should be noted that, in the present disclosure, the number of the guardrails 100 is not limited, and a plurality of guardrails 100 and a plurality of hobby guardrail sets 300 can be used at one location (for example, an entrance of a station) to form a guardrail set, and the plurality of guardrails 100 can be electrically connected to one control unit 200, that is, the plurality of guardrails 100 are controlled by one control unit 200 to control the guardrail 100 to switch between the first operating state and the second operating state. Specifically, the second processor 220 can be electrically connected to the electrically controlled driving devices of the plurality of guardrails 100, respectively.

Optionally, the guardrail groups of multiple sites can be further connected through a switch 230 (such as the switch 230 described above) so as to enable linkage between the guardrail groups of multiple sites. For example, when an accident occurs at one of the sites, the site can transmit a corresponding signal to the second processor 220 of the other guardrail group according to the selector, so that the second processor 220 controls the guardrail 100 of the corresponding guardrail group to be deployed or retracted.

In the following, several common operation modes of the diversion evacuation system provided based on the present disclosure will be briefly described by taking a station as an example of a practical application place with reference to the accompanying drawings: normal mode, peak mode and emergency mode.

And (3) a normal mode:

at this time, the flow of people is small. As shown in fig. 2, 4 and 8, the guardrail 100 is in the first working state, the first door 10 and the second door 20 are retracted, and the plurality of independent channels 400 are opened to guide the flow of people normally. The electromagnetic member 44 is in the power-off state, the push rod 441 of the electromagnetic member 44 is in the retracted position, the locking pin 461 of the electrically controlled locking member 46 is in the retracted state, the first infrared sensor 51 is shielded, and the second infrared sensor 52 is not shielded.

Peak mode:

at this time, the flow of people is large. The guardrail 100 needs to be switched from the first operating condition shown in fig. 8 to the second operating condition shown in fig. 9.

Specifically, peak mode is triggered when a preset time arrives or the system. First, the second processor 220 may trigger the alarm 250 to alarm and voice-prompt the passenger to pass through the desired maneuver area within a certain time (e.g., within 15 seconds). After the preset time, the second processor 220 may control the relay to be closed to energize the push rod 441 of the electromagnetic element 44, so that the push rod 441 of the electromagnetic element 44 is slowly extended out, the push rod 441 drives the double-sided rack 43 to slowly move, and the elastic reset element 45 starts to be pressed and shortened. When the detection shield of the first infrared sensor 51 is removed, it indicates that the rotation of the first door body 10 and the second door body 20 is started. When the first infrared sensor 51 is completely uncovered, the push rod 441 of the electromagnetic member 44 will be accelerated to protrude against the elastic force of the elastic restoring member 45 until the push rod 441 of the electromagnetic member 44 is stopped from protruding after the first infrared sensor 51 is covered, and at this time, the elastic restoring member 45 is pressed to the shortest.

When the second infrared sensor 52 is shielded, the locking pin 461 of the electrically controlled locking member 46 extends upward to lock the push rod 441 of the electromagnetic member 44. During the movement of the push rod 441 in the direction D, the double-sided rack 43 moves linearly and drives the first gear 41 and the second gear 42 to rotate, and the first door body 10 and the second door body 20 rotate along with the rotation and finally are located at the positions shown in fig. 5 and 9. At this time, the plural guardrails 100 and the plural iron horse guardrail sets 300 together define an S-shaped diversion channel 500 for diversion of the crowd.

In order to ensure that the push rod 441 of the electromagnetic element 44 is locked by the electrically controlled locking element 46, when the push rod 441 moves in the direction D, the determination can be made in the following manner:

after the push rod 441 detects that the first infrared sensor 51 is shielded, the second processor 220 reduces the power supply current of the electromagnetic element 44 and the shielding state of the second infrared sensor 52 to determine whether the electrically controlled locking element 46 has been extended out of the locking pin 461 and to lock the push rod 441 to retract after a certain period of time (e.g., 2 seconds). If the push rod 441 is locked by the locking pin 461, the second infrared sensor 52 will remain shielded when the push rod 441 reduces the supply current until the push rod 441 is powered off. When the current of the push rod 441 is reduced, the shielding of the second infrared sensor 52 is removed, which indicates that the push rod 441 is not locked by the locking pin 461, and at this time, the power supply current to the push rod 441 can be increased until the second infrared sensor 52 is shielded.

The current reduction process for the push rod 441 of the electromagnetic element 44 is performed for a predetermined number of times (for example, 3 times), and if all 3 attempts fail, the power is continuously supplied to the push rod 441 of the electromagnetic element 44, so as to keep the second infrared sensor 52 shielded until the peak-current mode exits.

The diversion evacuation device to switch from peak mode to normal mode is the reverse of the above described operation and will not be described in detail here.

Emergency mode:

in case of emergency or power failure, the guardrail 100 will be powered off and the power supply of the electrically controlled locking member 46 will be cut off. After power loss, the locking pin 461 of the electrically controlled locking element 46 retracts downwards, so that the locking pin 461 is quickly disengaged from the push rod 441 of the electromagnetic element 44. Therefore, the double-sided rack 43 is driven by the elastic reset piece 45 to move in the direction opposite to the direction D, so as to drive the first gear 41 and the second gear 42 to rotate, thereby driving the first door body 10 and the second door body 20 to rotate to the positions shown in fig. 3 and 8, at this time, the plurality of independent channels 400 are opened, and a large number of people can escape rapidly through the independent channels 400.

It should be noted that, according to an actual application scenario and an actual location, the diversion evacuation system may further have other operation modes, which is not limited in this disclosure.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
