[0021] As can be seen from the background technology, the operating efficiency of elevators needs to be improved.

[0022] In the elevator system provided in the embodiment of the present application, the elevator control panel and the machine room safety panel are installed in the machine room of the elevator system, the elevator control panel is used to control the operation of the elevator system, the machine room safety panel is used to obtain and process various machine room safety signals of the elevator system, and the elevator control panel and the machine room safety panel exchange data through the first safety bus, thereby realizing the overall operation and safety monitoring of the elevator system. The car top safety panel is installed on the top of the car of the elevator system, and is used to obtain and process the car safety signal in the car. The car top safety panel can process the safety data in the car and then transmit the processed car safety signal to the machine room safety panel through the second safety bus, so as to reduce the data load of the machine room safety panel, which is conducive to improving the operation efficiency of the machine room safety panel. The car top safety board has a position detection module to obtain the position of the car. During the operation of the elevator, if the position detection module obtains that the car is about to reach the preset floor, the car top safety board sends a preset position signal to the machine room safety board; the machine room safety board receives the preset position signal and synchronizes it to the elevator control board.

In this way, in the process from the car is about to arrive at the preset floor to the car arriving at the preset floor, the floor door and the car door have received the door opening command and start to open. Compared with the conventional elevator system in which the car starts to open the door only after reaching the preset floor, the time passengers wait for the door to open can be reduced, thereby improving the operation efficiency of the elevator.

However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in the present application can be implemented.

[0029] Figure 1 A schematic diagram of the circuit structure of an elevator system provided in an embodiment of the present application.

[0030] refer to Figure 1 On the one hand, an embodiment of the present application provides an elevator system, including: an elevator control panel 101, a machine room safety panel 102 and a car top safety panel 103, the elevator control panel 101 is used to control the operation of the elevator system; the machine room safety panel 102 is connected to the elevator control panel 101 through a first safety bus 111, and the machine room safety panel 102 is used to obtain a machine room safety signal in the elevator system; the car top safety panel 103 is connected to the machine room safety panel 102 through a second safety bus 121, and the car top safety panel 103 is used to obtain a car safety signal in the elevator system. Among them, the car top safety panel 103 has a position detection module 113, and the position detection module 113 is used to obtain the position of the car; during the operation of the elevator, the position detection module 113 obtains a preset position signal, and the preset position signal indicates that the car is about to arrive at the preset floor. The car top safety panel 103 sends the preset position signal to the machine room safety panel 102; the machine room safety panel 102 receives the preset position signal and synchronizes it to the elevator control panel. After the elevator control panel confirms that the car is about to arrive at the preset floor, it issues a door opening command to open the floor door of the preset floor and the car door of the car.

[0031] In the elevator system provided in the embodiment of the present application, the elevator control panel 101 and the machine room safety panel 102 are installed in the machine room of the elevator system. The elevator control panel 101 is used to control the operation of the elevator system, and the machine room safety panel 102 is used to obtain and process various machine room safety signals of the elevator system. The elevator control panel 101 and the machine room safety panel 102 exchange data through the first safety bus 111, thereby realizing the overall operation and safety monitoring of the elevator system. The car top safety panel 103 is installed on the top of the car of the elevator system, and is used to obtain and process the car safety signal in the car. The car top safety panel 103 can process the safety data in the car and then transmit the processed car safety signal to the machine room safety panel 102 through the second safety bus 121, so as to reduce the data load of the machine room safety panel 102, which is conducive to improving the operation efficiency of the machine room safety panel 102. The car top safety panel 103 has a position detection module 113 to obtain the position of the car. During the operation of the elevator, if the position detection module 113 obtains that the car is about to reach the preset floor, the car top safety panel 103 sends a preset position signal to the machine room safety panel 102; the machine room safety panel 102 receives the preset position signal and synchronizes it to the elevator control panel. After the elevator control panel confirms that the car is about to arrive at the preset floor, it issues a door opening command to open the floor door and the car door of the preset floor. In this way, in the process from the time the car is about to arrive at the preset floor to the time the car arrives at the preset floor, the floor door and the car door have received the door opening command and start to open. Compared with the conventional elevator system in which the car starts to open the door only after arriving at the preset floor, the time passengers wait for the door to open can be reduced, thereby improving the operation efficiency of the elevator.

[0032] The preset floor can be the floor where the passengers outside the elevator press the up button or the down button, or the floor that the passengers in the elevator arrive at by indicating the floor buttons.

[0033] In some embodiments, the detection signal of the position detection module 113 includes an upper leveling signal, a door zone signal, and a lower leveling signal.

[0034] During the process of the car going up to the preset floor, the position detection module will sequentially obtain the upper leveling signal, the door area signal and the lower leveling signal. In this way, during the upward process of the car, after the position detection module sequentially obtains the upper leveling signal and the door area signal of the preset floor, before obtaining the lower leveling signal of the preset floor, it can be determined that the car is about to arrive at the preset floor.

[0035] During the process of the car descending to the preset floor, the position detection module will sequentially obtain the lower leveling signal, the door area signal and the upper leveling signal. In this way, during the descending process of the car, after the position detection module sequentially obtains the lower leveling signal and the door area signal of the preset floor, before obtaining the upper leveling signal of the preset floor, it can be determined that the car is about to arrive at the preset floor.

[0036] The door zone signal refers to the signal obtained by the position detection module when the height difference between the sill of the car and the sill of the landing door in the vertical direction does not exceed 10 cm.

[0037] The upper leveling signal can be detected by the upper leveling sensor located on the top of the car. Specifically, when the distance between the upper leveling sensor located on the top of the car and the lower edge of the floor door is less than a preset distance during the upward movement of the car, the upper leveling signal is triggered; when the distance between the upper leveling sensor located on the top of the car and the upper edge of the floor door is less than a preset distance during the downward movement of the car, the upper leveling signal is triggered.

[0038] The lower leveling signal can be detected by the lower leveling sensor located at the bottom of the car. Specifically, when the lower leveling sensor located at the bottom of the car detects that the distance from the lower edge of the floor door is less than a preset distance during the upward movement of the car, the lower leveling signal is triggered; when the lower leveling sensor located at the bottom of the car detects that the distance from the upper edge of the floor door is less than a preset distance during the downward movement of the car, the lower leveling signal is triggered.

[0039] In some embodiments, the upper leveling signal, the door zone signal and the lower leveling signal are photoelectric signals or magnetic signals.

[0040] refer to Figure 1 In some embodiments, the elevator system further includes: a brake power supply 104 and a brake system 105. When the brake system 105 is disconnected from the brake power supply 104, the brake system 105 brakes the elevator system; the machine room safety panel 102 further includes: a brake switch module 112. One end of the brake switch module 112 is connected to the brake power supply 104, and the other end of the brake switch module 112 is connected to the brake system 105. The brake switch module 112 is used to control the conduction or disconnection of the brake system 105 and the brake power supply 104.

[0041] During the period when the car has arrived at the preset floor, the position detection module 113 will continue to obtain the upper leveling signal, the door area signal and the lower leveling signal. If any of the upper leveling signal, the door area signal and the lower leveling signal is disconnected, the machine room safety board 102 controls the disconnection of the brake switch module to achieve the braking of the elevator system. That is to say, after the car has arrived at the preset floor, during the upward or downward movement of the passenger, if the position of the car moves, the machine room safety board 102 controls the disconnection of the brake switch module to achieve the elevator braking, thereby ensuring the safety of the passengers.

[0042] In some embodiments, during the period from when the position detection module 113 obtains the preset position signal to when the position detection module 113 obtains that the car has arrived at the preset floor, the machine room safety panel 102 controls the brake switch module 112 to be turned on. In this way, during the period from when the position detection module 113 obtains the preset position signal to when the position detection module 113 obtains that the car has arrived at the preset floor, the brake switch module 112 will not be actively disconnected, causing the elevator system to be braked, so that the car can continue to run to the alignment position of the preset floor during the opening of the car door and the floor door, thereby facilitating the entry and exit of passengers. Since the time from when the position detection module 113 obtains the preset position signal to when the position detection module 113 obtains that the car has arrived at the preset floor is short, the machine room safety panel 102 only keeps the brake switch module 112 turned on during this period, which has little impact on the elevator system.

[0043] Figure 2 A schematic diagram of the circuit structure of another elevator system provided in an embodiment of the present application.

[0044] refer to Figure 2 In some embodiments, the brake switch module 112 includes a first switch K1 and a second switch K2 connected in series. When one of the first switch K1 or the second switch K2 is disconnected, the brake system 105 is controlled to be disconnected from the brake power supply 104, so that the elevator system is braked. The redundant design of the two first switches K1 and the second switch K2 connected in series can improve the stability of the brake switch module 112 and avoid the situation where the elevator system cannot be braked due to the failure of a single switch.

[0045] In some embodiments, the car top safety panel 103 further includes: a car door lock detection module 123, which is used to obtain the open or closed state of the car door; the machine room safety panel 102 further includes: a floor door lock detection module 122, which is used to obtain the open or closed state of the floor door. Usually during the operation of the elevator, if the car door lock detection module obtains that the car door is not closed and / or the floor door lock detection module obtains that the floor door is not closed, the corresponding safety signal is transmitted to the machine room safety panel 102, and the machine room safety panel 102 will determine that the elevator system is in a fault state, thereby disconnecting the brake switch module 112 to enable the elevator system to brake urgently to avoid danger.

[0046] In the elevator system provided by the embodiment of the present application, during the operation of the elevator, after the position detection module 113 obtains that the car is about to arrive at the preset floor, the car top safety panel 103 sends a preset position signal to the machine room safety panel 102; the machine room safety panel 102 receives the preset position signal and synchronizes it to the elevator control panel 101, and the elevator control panel 101 confirms that the car is about to arrive at the preset floor and issues a door opening command to open the floor door of the preset floor and the car door of the car. In this way, during the period from when the position detection module 113 obtains that the car is about to arrive at the preset floor to when the position detection module 113 obtains that the car has arrived at the preset floor, the machine room safety panel 102 may misjudge that the elevator system is in a fault state. In order to enable the elevator system to operate normally during the pre-door opening process, the car top safety panel 103 does not determine the state of the car door lock detection module 123, and the machine room safety panel 102 does not determine the state of the floor door lock detection module 122 during the period from when the position detection module 113 obtains that the car is about to arrive at the preset floor to when the position detection module 113 obtains that the car has arrived at the preset floor. In this way, during the period from when the position detection module 113 obtains that the car is about to arrive at the preset floor to when the position detection module 113 obtains that the car has arrived at the preset floor, the car door lock detection module 123 and the floor door lock detection module 122 do not affect the determination of the machine room safety panel 102, and the machine room safety panel 102 will not determine the door opening operation of the elevator during operation, that is, it will not cause the machine room safety panel 102 to misjudge the elevator system as a fault state, so that the elevator system can still operate normally during the pre-door opening process. And because the position detection module 113 obtains that the car is about to arrive at the preset floor, the time from when the position detection module 113 obtains that the car has arrived at the preset floor is short, and disconnecting the car door lock detection module 123 and the floor door lock detection module 122 only during this period has little impact on the elevator system.

[0047] After the position detection module 113 obtains that the car has arrived at the preset floor, the car top safety panel 103 starts to determine the state of the car door lock detection module 123, and the machine room safety panel 102 starts to determine the state of the floor door lock detection module 122. This ensures that after the car has arrived at the preset floor, it can accurately determine whether the car has moved unexpectedly.

[0048] In some embodiments, after the position detection module 113 obtains that the car has arrived at the preset floor, before the car door lock detection module 123 obtains that the car door is closed, and before the floor door lock detection module 122 obtains that the floor door lock is closed, the machine room safety panel 102 controls the brake switch module 112 to be disconnected. That is, after the car has arrived at the preset floor, during the passengers' getting on and off, the machine room safety panel 102 controls the brake switch module 112 to be disconnected, so as to avoid the danger caused by the movement of the car due to the failure of the elevator system during the passengers' getting on and off.

[0049] In some embodiments, during the period from when the position detection module 113 obtains the preset position signal to when the position detection module 113 obtains that the car has arrived at the preset floor, the position detection module 113 detects that the position of the car is abnormal, and the car top safety panel 103 sends a position abnormality signal to the machine room safety panel 102; after receiving the position abnormality signal, the machine room safety panel 102 controls the brake switch module 112 to disconnect.

[0050] In some embodiments, the position abnormality signal includes: the position detection module 113 obtains a preset position signal, and the time from when the position detection module 113 obtains that the car has arrived at the preset floor exceeds the preset arrival time.

[0051] For example, when the detection signal of the position detection module 113 includes an upper leveling signal, a door area signal, and a lower leveling signal. During the process of the car going down to the preset floor, the position detection module will sequentially obtain the lower leveling signal, the door area signal, and the upper leveling signal. If during the downward process of the car, the position detection module sequentially obtains the lower leveling signal and the door area signal of the preset floor and exceeds the preset arrival time, but still fails to obtain the lower leveling signal of the preset floor, then the car top safety board 103 sends a position abnormality signal to the machine room safety board 102. During the process of the car going up to the preset floor, the position detection module sequentially obtains the upper leveling signal, the door area signal, and the lower leveling signal. If during the upward process of the car, the position detection module sequentially obtains the upper leveling signal and the door area signal of the preset floor and exceeds the preset arrival time, but still fails to obtain the lower leveling signal of the preset floor, then the car top safety board 103 sends a position abnormality signal to the machine room safety board 102.

[0052] In some embodiments, the position abnormality signal includes: the position detection module obtains that the car has arrived at the preset floor and the dwelling time is less than the preset dwelling time. Usually, the purpose of the car arriving at the preset floor is for passengers to get on or off the car. If the position detection module obtains that the car has arrived at the preset floor and the dwelling time is less than the preset dwelling time, it can be determined that the car is staying abnormally.

[0053] In the elevator system provided in the embodiment of the present application, the elevator control panel 101 and the machine room safety panel 102 are installed in the machine room of the elevator system, the elevator control panel 101 is used to control the operation of the elevator system, the machine room safety panel 102 is used to obtain and process various machine room safety signals of the elevator system, and the elevator control panel 101 and the machine room safety panel 102 exchange data through the first safety bus 111, thereby realizing the overall operation and safety monitoring of the elevator system. The car top safety panel 103 is used to obtain and process the car safety signal in the car, and the car top safety panel 103 can process the safety data in the car and then transmit the processed car safety signal to the machine room safety panel 102 through the second safety bus 121, so as to reduce the data load of the machine room safety panel 102, which is conducive to improving the operation efficiency of the machine room safety panel 102. The car top safety panel 103 has a position detection module 113 to obtain the position of the car. During the operation of the elevator, if the position detection module 113 obtains that the car is about to reach the preset floor, the car top safety panel 103 sends a preset position signal to the machine room safety panel 102; the machine room safety panel 102 receives the preset position signal and synchronizes it to the elevator control panel 101. After the elevator control panel 101 confirms that the car is about to arrive at the preset floor, it issues a door opening command to open the floor door and the car door of the preset floor. In this way, in the process from the time the car is about to arrive at the preset floor to the time the car arrives at the preset floor, the floor door and the car door have received the door opening command and start to open. Compared with the conventional elevator system in which the car starts to open the door only after arriving at the preset floor, the time passengers wait for the door to open can be reduced, thereby improving the operation efficiency of the elevator.

[0054] Correspondingly, another embodiment of the present application further provides a pre-door opening method for an elevator system, which is applied to the elevator system in the above embodiment to realize the pre-door opening of the elevator system. For the parts that are the same or corresponding to the previous embodiment, reference can be made to the corresponding description of the above embodiment, and will not be described in detail below.

[0055] The pre-door opening method of the elevator system includes:

[0056] After receiving the elevator call signal, the elevator control panel 101 issues a running command to make the car run to the preset floor; during the operation of the elevator, after the position detection module 113 obtains the preset position signal, the car top safety panel 103 sends the preset position signal to the machine room safety panel 102; the machine room safety panel 102 receives the preset position signal and synchronizes it to the elevator control panel 101. After the elevator control panel 101 confirms that the car is about to arrive at the preset floor, it issues a door opening command to open the floor door and the car door of the preset floor. In this way, in the process from when the car is about to arrive at the preset floor to when the car arrives at the preset floor, the floor door and the car door have received the door opening command and started to open. Compared with the conventional elevator system in which the car starts to open the door only after reaching the preset floor, the time for passengers to wait for the door to open can be reduced, thereby improving the operation efficiency of the elevator.

[0057] The elevator call signal received by the elevator control panel 101 may be a signal sent by a passenger outside the elevator at a preset floor by pressing an up button or a down button, or the elevator call signal may be a signal indicated by a passenger in the elevator arriving at a preset floor by pressing a floor button.
