As shown in fig. 2, the striker 10 includes a vertical portion 11 and pre-contact portions 12 provided at upper and lower ends of the vertical portion 11. The pre-contact portion 12 provided at the upper end portion of the vertical portion 11 is inclined upward from the connection with the vertical portion 11; the precontacted portion 12 provided at the lower end portion of the vertical portion 11 is inclined downward from the connection with the vertical portion 11.
The end of each travel switch 40 is provided with a pivotable trigger roller 41. The trigger roller 41 of each travel switch 40 is provided so as to be able to contact the pre-contact portion 12 and the vertical portion 11 of the striker 10.
The purpose of the pre-contact 12 is to prevent the striker 10 from damaging the travel switch 40 with too high a speed of movement of the car 20, while the purpose of the upright 11 is to trigger the travel switch 40. Therefore, in the case where the striker 10 moves to the flat position of the corresponding floor together with the car 20, when the trigger roller 41 of the travel switch 40 of the corresponding floor comes into contact with the intermediate position of the vertical portion 11 of the striker 10, the corresponding travel switch is triggered. Further, when the positions of the striker 10 and the travel switch 40 are set, the car is stopped at the level position of each floor, and the travel switch 40 is arranged to correspond to the intermediate position of the vertical portion 11 of the striker 10, respectively.

The travel switch is a common small-current master control electric appliance. The contact of the production mechanical moving part is enabled to act by utilizing the collision of the production mechanical moving part to realize the connection or disconnection of the control circuit, thereby achieving a certain control purpose. In an exemplary embodiment of the present invention, when the striker 10 is in contact with a respective travel switch 40, the respective travel switch 40 is activated, each travel switch 40 having a first set of contacts and a second set of contacts (not shown). According to an embodiment of the invention, the first set of contacts are normally open contacts and the second set of contacts are normally closed contacts, the first set of contacts being closed and the second set of contacts being opened when the travel switch is triggered.
Fig. 3 is a schematic diagram showing a configuration of a fault-tolerant layer electrical system according to an exemplary embodiment of the present invention. As shown in fig. 3, the travel switch 40 is provided with a first connector assembly 42. Wherein one end of the first connector assembly 42 is connected to a first set of contacts and the other end is connected to an electrical interlock device 50.
The anti-mislayer electrical system according to an exemplary embodiment of the present invention may further include an electrical interlock 50 that may include an electromagnetic lock that engages when powered, thereby allowing the elevator door to open.
In an exemplary embodiment of the present invention, the electrical interlock device 50 is electrically connectable with the first set of contacts of the respective travel switch 40, and the electrical interlock device 50 is powered when electrically connected with the first set of contacts of the respective travel switch 40. The electrical interlock 50 is powered to actuate the electromagnetic lock, which is embodied as an electromagnetic lock actuation, thereby allowing the elevator door to open.
The principle of operation of the error proofing layer electrical system according to an exemplary embodiment of the present invention is: a central processing unit (Central Processing Unit, CPU) of the elevator control system is combined with a peripheral sensor to realize absolute position coding record and carry out absolute floor judgment. When the CPU of the elevator control system operates the elevator to a certain floor according to the absolute floor judgment, outputting a power supply of an electromagnetic lock for the corresponding floor, and only when the elevator is stopped at the floor, the striker 10 triggers the travel switch 40, and a first group of contacts of the travel switch 40 are closed, so that the electric interlocking device 50 is powered, the electromagnetic lock acts, and the elevator door is allowed to be opened; if the CPU of the elevator control system determines that the absolute floor is wrong or crashed, and the actual elevator stopping floor is inconsistent with the CPU of the elevator control system, even if the elevator control system mistakenly outputs the power supply of the electromagnetic lock for the non-elevator actual stopping floor, the first group of contacts of the travel switch 40 do not act and do not act the electromagnetic lock due to the floor mistake, so that the mistaken opening of the elevator door is avoided, and the function of preventing the floor from being mistaken through the electrical system is formed.
Therefore, the anti-dislocation electrical system according to the exemplary embodiment of the present invention is used as a set of independent peripheral electrical judgment system to cooperate with the CPU of the elevator control system to perform redundancy judgment, so as to prevent the CPU of the elevator control system from causing the elevator door lock to malfunction once the CPU of the elevator control system fails or is disordered.
In addition, the error proofing layer electrical system of the exemplary embodiments of the present invention also has a need for detecting and monitoring it as a stand-alone peripheral electrical judgment system.

That is, the second set of contacts of each travel switch 40 and the elevator control system are connected in series.
The travel switch 40 feeds back the closing or opening of the second set of contacts and is then judged by the elevator control system, which can judge from the individual door zone signals whether the elevator is in the area where the travel switch 40 is triggered, i.e. whether the car is stopped at the level of the corresponding floor, if the car is stopped at the level of the corresponding floor, the second set of contacts fed back to the corresponding travel switch 40 of the elevator control system should be open, otherwise should be closed. The action signal of the travel switch 40 includes the triggering of the travel switch 40 and the non-triggering of the travel switch 40, and as the travel switch 40 is not triggered, the first set of contacts are opened and the second set of contacts are closed; when the travel switch 40 is triggered, the first set of contacts is closed and the second set of contacts is open, so that the series connection of the second set of contacts and the elevator control system forms a circuit for feeding back an action signal of the travel switch 40, and further forms a feedback circuit for detecting the action of the first set of contacts of the travel switch 40, and can be used for judging whether the first set of contacts have adhesion faults or not.

When the elevator control system CPU judges that the elevator is operated to a certain floor according to the absolute floor, outputting a power supply of an electromagnetic lock for the corresponding floor, and when and only when the elevator is stopped at the floor, triggering a travel switch 40 by a striker 10, closing a first group of contacts of the travel switch 40, so that the electric interlocking device 60 is powered, the electromagnetic lock acts, and door opening is allowed; if the CPU of the elevator control system judges that the absolute floor is wrong or crashed, when the actual elevator stopping floor is inconsistent with the judging floor of the CPU of the elevator control system, even if the elevator control system outputs the power supply of the electromagnetic lock for the non-elevator actual stopping floor by mistake, the first group of contacts of the travel switch 40 do not act due to the mistake of the floor, so that the wrong electromagnetic lock is not acted, and the false opening of the elevator door is avoided, thereby forming the function of preventing the fault floor through the electrical system.
Therefore, the fault-prevention layer implementation method using the electrical system according to the exemplary embodiment of the present invention is used as a set of independent peripheral electrical judgment method to perform redundancy judgment in cooperation with the CPU of the elevator control system, so as to prevent the CPU of the elevator control system from causing the misoperation of the elevator door lock once the CPU of the elevator control system fails or is disordered.
