The main function of the safety isolation and protection device for the automatic fare collection system is to ensure that only passengers with valid tickets or those who have passed identity verification can pass, thereby maintaining public order and safety.

[0003] However, in the actual operation process, the safety isolation and protection device for the automatic fare collection system may encounter various emergency accidents, such as fires, earthquakes, power failures, etc. In these emergency situations, in order to ensure the safety of personnel, it is usually necessary to quickly open the ticket gate to achieve unobstructed passage so that internal personnel can quickly evacuate. However, the existing design of the safety isolation and protection device for the automatic fare collection system often has a problem: when the ticket gate loses power due to an emergency accident, the ticket gate cannot be automatically opened and requires manual operation by staff to open the ticket gate. This not only delays the rescue time, hinders the rapid evacuation of personnel, but also limits the applicability and emergency response ability of the ticket gate to a certain extent.

[0004] Therefore, how to provide a safety isolation and protection device for the automatic fare collection system with the function of automatically opening the gate when power is off and improving the response speed and evacuation efficiency of the ticket gate in emergency accidents is a technical problem that those skilled in the art need to solve at present.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0039] In order to enable those skilled in the art in the technical field to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] See Figures 1 - 2 , a safety isolation and protection device for an automatic fare collection system provided by the present application includes a turnstile body 1, a rotating rod 2 is rotatably connected to the turnstile body 1, a wing is fixedly provided on the rotating rod 2, and a first driven gear 21 is fixedly provided at the upper end of the rotating rod 2; a transmission member 3, the transmission member 3 includes a second driven gear 31, and the transmission member 3 can adjust the second driven gear 31 to be in an initial position or a working position; a driving member 4, the output end of the driving member 4 is connected to the driving gear 41, when the second driven gear 31 is in the working position, the second driven gear 31 correspondingly meshes with the first driven gear 21 and the driving gear 41; or, when the second driven gear 31 is in the initial position, the second driven gear 31 is disengaged from meshing with the first driven gear 21 and the driving gear 41; a rebound member 5 is provided at the lower end of the rotating rod 2, when the second driven gear 31 is in the initial position, the rebound member 5 can rotate the rotating rod 2 so that the wing is in an open state; a control system, both the transmission member 3 and the driving member 4 are in signal connection with the control system.

[0041] That is to say, the turnstile body 1 is connected to the rotating rod 2 and realizes the stable rotation of the rotating rod 2. A wing is fixedly installed on the rotating rod 2, and the wing is an important part for controlling the opening and closing of the passage in the safety isolation and protection device of the automatic fare collection system.

[0042] The upper end of the rotating rod 2 is also fixedly provided with a first driven gear 21. The transmission member 3 is a key transmission component in the safety isolation and protection device of the automatic fare collection system, including a second driven gear 31. The position of the second driven gear 31 is adjustable, and it can be switched between the initial position and the working position. Specifically, when the transmission member 3 is powered on, the second driven gear 31 is located at the working position at this time. When the transmission member 3 is powered off, the second driven gear 31 is located at the initial position. When the second driven gear 31 is in the working position, it will mesh with the first driven gear 21 and the driving gear 41 at the same time, thus forming a complete power transmission path. When the second driven gear 31 is in the initial position, it is disengaged from both the first driven gear 21 and the driving gear 41 and does not participate in power transmission.

[0043] The driving member 4 is the power source of the safety isolation and protection device of the automatic fare collection system. It is responsible for providing rotational power. The output end of the driving member 4 is connected to the driving gear 41. When the driving member 4 is started, the driving gear 41 will rotate accordingly. When the second driven gear 31 is in the working position, the driving member 4 transmits power to the rotating rod 2 through the driving gear 41 and the second driven gear 31, causing it to rotate.

[0044] The rebounding member 5 is arranged at the lower end of the rotating rod 2. When the second driven gear 31 is in the initial position, the rebounding member 5 will use its own elastic force to make the rotating rod 2 rotate.

[0045] During normal operation, the transmission member 3 adjusts the second driven gear 31 to the working position, and then starts the driving member 4 to make the driving gear 41 rotate. Through the meshing of the second driven gear 31 and the first driven gear 21, power is transmitted to the rotating rod 2, causing it to rotate and close the door wing. When an accidental power failure occurs, the second driven gear 31 returns to the initial position. At this time, the rebounding member 5 will use its own elastic force to make the rotating rod 2 rotate and open the door wing. Furthermore, an automatic fare collection system safety isolation and protection device provided by the present application has the function of automatically opening the gate when power is off, improving the response speed and evacuation efficiency of the turnstile in case of emergency accidents.

[0046] Specifically, on the basis of the above embodiments, refer to Figure 3 , the transmission member 3 includes a transmission rod 32. The transmission rod 32 is arranged between the rotating rod 2 and the driving member 4. A limiting plate 33 is provided at the top of the transmission rod 32; a first elastic member 34 and a movable gear groove 35. The first elastic member 34 and the movable gear groove 35 are both sleeved on the transmission rod 32, and the first elastic member 34 is located between the limiting plate 33 and the movable gear groove 35. The second driven gear 31 is connected to the movable gear groove 35 through a bearing 36; an electromagnet 37 is fixedly arranged on the transmission rod 32. The electromagnet 37 can make the movable gear groove 35 slide on the transmission rod 32, and the electromagnet 37 is in signal connection with the control system.

[0047] Specifically, the transmission rod 32 is the main part of the transmission member 3 and is located between the rotating rod 2 and the driving member 4. The limiting plate 33 is arranged at the top of the transmission rod 32 and is used to limit the sliding range of the first elastic member 34 on the transmission rod 32. The first elastic member 34 is sleeved on the transmission rod 32 and is located between the limiting plate 33 and the movable gear groove 35. The first elastic member 34 provides an elastic force to enable the movable gear groove 35 to return to the initial position when the electromagnetic force of the electromagnet 37 is lost.

[0048] The movable gear groove 35 is also sleeved on the transmission rod 32 and is used to accommodate the second driven gear 31. The bearing 36 is used to connect the second driven gear 31 and the movable gear groove 35, enabling the second driven gear 31 to rotate within the movable gear groove 35, reducing friction and wear.

[0049] The electromagnet 37 is fixedly arranged on the transmission rod 32. When it is energized during normal operation, the electromagnet 37 can generate a magnetic force to move the movable gear groove 35 in a direction away from the electromagnet 37. Due to the action of the first elastic member 34, the movable gear groove 35 is in the working position on the transmission rod 32.

[0050] When an accidental power failure occurs, the electromagnet 37 loses its magnetic force. Under the elastic force of the first elastic member 34, the movable gear groove 35 slides downward, driving the second driven gear 31 back to the initial position. The second driven gear 31 disengages from both the first driven gear 21 and the driving gear 41 and does not participate in power transmission.

[0051] Based on the above embodiments, refer to Figure 4 , the rebounding member 5 includes a housing 51. A through hole is provided at the center of the housing 51, and a first clamping block 52 is provided on the inner wall of the through hole. A second clamping block 22 is provided on the outer wall of the bottom end of the rotating rod 2; a second elastic member 53, the second elastic member 53 is sleeved on the rotating rod 2, and the rotating rod 2 can be inserted into the through hole so that one end of the second elastic member 53 abuts against the first clamping block 52 and the other end abuts against the second clamping block 22.

[0052] That is to say, a through hole is provided at the center of the housing 51 to allow the rotating rod 2 to be inserted therethrough. A first clamping block 52 is carefully provided on the inner wall of the through hole. The first clamping block 52 is firmly arranged on the inner wall of the through hole of the housing 51, and its shape and position are to ensure stable abutment with one end of the second elastic member 53. A second clamping block 22 is provided on the outer wall of the bottom end of the rotating rod 2.

[0053] The second elastic member 53 is closely sleeved on the rotating rod 2. When the rotating rod 2 is inserted into the through hole of the housing 51, one end of the second elastic member 53 abuts against the first clamping block 52 and the other end abuts against the second clamping block 22, enabling the second elastic member 53 to exert a continuous elastic force on the rotating rod 2.

[0054] Normal working state

[0055] In the normal working state of the safety isolation and protection device for the automatic fare collection system, the transmission member 3 adjusts the second driven gear 31 to the working position. At this time, the driving member 4 is activated, and through the meshing of the second driven gear 31 and the first driven gear 21, power is transmitted to the rotating rod 2, causing it to rotate and close the door wing. During this process, the second elastic member 53 of the rebounding member 5 is compressed, storing elastic potential energy.

[0056] Accidental power-off state

[0057] When the safety isolation and protection device for the automatic fare collection system encounters an accidental power-off situation, the electromagnet 37 in the transmission member 3 loses its attraction force, and the movable gear groove 35 slides downward under the elastic force of the first elastic member 34, driving the second driven gear 31 back to the initial position. At this time, the second driven gear 31 disengages from both the first driven gear 21 and the driving gear 41 and no longer participates in power transmission. At the same time, the second elastic member 53 in the rebounding member 5 begins to release the stored elastic potential energy, pushing the rotating rod 2 to rotate. The rotation of the rotating rod 2 drives the door wing to open quickly, ensuring that personnel can be quickly evacuated in case of an emergency.

[0058] Both the first elastic member 34 and the second elastic member 53 are springs, and the driving member 4 is a motor. Specifically, the spring can be selected as a spring with a high elastic coefficient and fatigue resistance.

[0059] Based on the above embodiments, the control system further includes a control instruction recognition module. The control instruction recognition module includes a protocol capture unit for capturing service control instructions; an instruction processing unit for parsing and analyzing instructions; and a signal transmission module for establishing a signal connection with a preset database and used for transmitting correct service instructions.

[0060] That is to say, the protocol capture unit is responsible for capturing service control instructions from an external communication network (such as Ethernet, serial communication, etc.), and can identify and receive data packets conforming to a specific communication protocol. The data packets contain instructions for controlling the express access gate, and the captured data packets will be sent to the instruction processing unit for further processing.

[0061] After receiving the data packet from the protocol capture unit, the instruction processing unit first parses it to extract the control instructions and relevant parameters therein. Subsequently, the instruction processing unit compares these instructions with the preset instruction format and rules to ensure the correctness of the instructions. More importantly, the instruction processing unit will compare with the data in the preset database. This database contains all normal and authorized control instructions and their corresponding parameter ranges. If the instruction processing unit finds a matching normal instruction in the database, it will further prepare the instruction for execution; if no matching item is found, the instruction is considered abnormal.

[0062] The signal transmission module establishes a stable signal connection with a preset database for real-time querying and comparison of instruction data. When the instruction processing unit confirms that an instruction is normal and legal, the signal transmission module is responsible for transmitting the instruction to the corresponding actuator to perform an operation.

[0063] If an instruction is identified as abnormal or unauthorized, the signal transmission module will not transmit the instruction and may trigger an alarm system or take other security measures (such as blocking the further spread of the abnormal instruction).

[0064] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0065] Specific examples are used in this article to elaborate on the principles and implementation modes of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
