[0023] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] It should be noted that although the functional modules are divided in the system schematic diagram and the logical sequence is shown in the flowchart, in some cases, the steps shown or described may be executed in a different module division from that in the system or a different sequence from that in the flowchart. Terms such as "first", "second", etc. in the specification, claims and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0025] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0026] Refer to Figure 1 , Figure 1 which is a module diagram of the first flat floor inductor provided by some embodiments of the present application; the flat floor inductor 100 includes a signal processing module 110, an infrared transceiver module 120, a digital output module 130, a communication module 140, a storage module 150, a status indication module 160, a normal power supply 170, a backup power supply 180 and a power supply switching module 190. The infrared transceiver module, the digital output module, the communication module, the storage module and the status indication module are all connected to the signal processing module respectively.

[0027] The infrared transceiver module includes an infrared emission module and an infrared reception module. The infrared emission module and the infrared reception module are horizontally installed on both sides of the flat floor inductor. The infrared emission module emits a modulated infrared signal, which is received and recognized by the corresponding infrared reception module. When the infrared signal is blocked by the elevator car, the infrared signal is interrupted, and the signal processing module controls the corresponding digital output module to output a digital signal according to the interruption situation of the infrared signal. It should be noted that the signal processing module includes a microprocessor. In the Figure 1 shown flat floor inductor, multiple infrared transceivers are connected to 1 microprocessor, and this processor controls multiple digital output modules to output multiple digital signals. When the elevator car passes by the infrared transceiver module and blocks the infrared rays of the infrared transceiver module, the infrared transceiver module sends a blocking signal to the signal processing module, thereby controlling the output of the elevator digital signal. In the embodiments of the present application, several upper infrared modules and the same number of lower infrared modules are divided into a group, and one group corresponds to the output of one digital signal. There are multiple groups in the infrared transceiver module. Therefore, 1 flat floor inductor provided by the embodiments of the present application can control the output of multiple digital signals. Compared with the solution in the related art where one flat floor inductor corresponds to one digital signal, the number of flat floor inductors required for the elevator is reduced, and multiple digital signal outputs are integrated into one flat floor inductor, reducing the volume of the device.

[0028] It should be noted that in the embodiments of the present application, the signal processing module controls the infrared transceiver module to emit modulated infrared rays. In the related art, the flat layer inductor uses modulated infrared rays with a fixed frequency. However, in the embodiments of the present application, different modulation frequencies are set for each infrared transceiver module to distinguish different channels. At the same time, each channel emits infrared signals in a time-sharing manner, which can effectively avoid the interference of external light and the crosstalk of bypass infrared signals.

[0029] The communication module is connected to the signal processing module. The communication module is used for the communication between the flat layer inductor and the elevator controller. The signal processing module sends the switch quantity output situation of the flat layer inductor to the elevator controller through the communication module to determine whether the flat layer inductor outputs normally. If the flat layer inductor outputs switch quantity, but the elevator controller does not detect its output, this state will be fed back to the elevator controller to prompt the output failure of the flat layer inductor.

[0030] Optionally, in the case of long-term non-use, the elevator will enter the standby state. When the flat layer inductor receives the elevator standby signal through the communication module, it enters the standby mode and reduces the frequency of infrared signal transceiver. In the normal operation state, the frequency of infrared signal transceiver in the flat layer inductor is at the microsecond level, while in the standby state, the infrared transceiver frequency can be adjusted to the second level. At the same time, the switch quantity module and the status indication module are turned off, and only the communication function is retained, and the communication frequency is reduced to achieve the purpose of reducing power consumption. When the elevator resumes normal operation, the normal operation mode is sent to the flat layer inductor, and the flat layer inductor resumes normal operation. When the elevator resumes normal operation, the normal operation signal is sent to the flat layer inductor, and the flat layer inductor resumes normal operation.

[0031] The storage module is connected to the signal processing module. The storage module is used to store elevator parameters, and the elevator parameters include the number of elevator floors, the current floor, etc.; in addition, the storage module is also used to store the key corresponding to the elevator. When the elevator is powered on, the elevator controller and the flat layer inductor establish a communication connection through the communication module. The flat layer inductor sends the key to the elevator controller. The elevator controller identifies whether the flat layer inductor is a legal device. If the identification passes, the elevator can operate normally; otherwise, the elevator controller issues a prompt or cannot respond to the operation instruction to prevent users from using illegal devices and improve the reliability of elevator operation.

[0032] Optionally, the storage module can also be used to store encryption formulas. When the elevator is powered on, the elevator controller and the flat layer inductor establish a communication connection through the communication module. The elevator controller sends a random password to the flat layer inductor. The flat layer inductor calculates the random key through the stored encryption formula and sends the random key to the elevator controller. The elevator controller identifies whether the flat layer inductor is a legal device through the key. When it is determined that the flat layer inductor is a legal device, the elevator can operate normally, which can prevent users from using illegal devices and improve the reliability of elevator operation.

[0033] The status indication module is connected to the signal processing module. The status indication module is used to display the current status of the elevator, and these statuses include but are not limited to: the ON / OFF status output by the digital input / output module, the elevator running status, the communication of the leveling inductor, faults, encryption status, etc. The status indication module specifically includes multiple indicator lights. Taking the output of the digital input / output module as an example, one indicator light can represent the output status of one digital input / output module. The indicator light can indicate the ON / OFF of the digital input / output module output by displaying two different colors; the indicator light can also indicate the ON / OFF of the digital input / output module output by using different flashing frequencies.

[0034] The leveling inductor also includes a normal power supply, a backup power supply, and a power supply switching module. Under normal operation of the elevator, the normal power supply is used to supply power to the leveling inductor; in the case of the elevator running away when power is cut off, the leveling inductor switches to the backup power supply through the power supply switching module to ensure that the elevator can continuously record the current floor position during the elevator running state.

[0035] Refer to Figure 2 , Figure 2 which is the module diagram of the second leveling inductor provided by some embodiments of this application; different from the first leveling inductor shown in Figure 1 the signal processing module of the second leveling inductor includes multiple microprocessors. One set of infrared transceiver modules corresponds to 1 microprocessor. 1 microprocessor controls the output of one digital input / output module, and 1 microprocessor controls one status indication module to perform status indication. Information exchange is carried out between each microprocessor through a communication bus. Compared with the first leveling inductor in Figure 1 the output control of each digital input / output is independent of each other, reducing the risk of all digital input / output outputs failing due to microprocessor faults or communication line faults. In addition, since the infrared transceiver module uses a time-sharing output method to transmit and receive modulated infrared signals of different frequencies, in the leveling inductor with multiple microprocessors, the infrared signal transceiver status is confirmed through the communication bus to achieve time-sharing infrared transmission and reception control.

[0036] Refer to Figure 3 , Figure 3Top view of the flat floor inductor provided by some embodiments of the present application; The first upper infrared module includes a first upper infrared transmitting module 300 located on the left side of the flat floor inductor 100 and a first upper infrared receiving module 310 located on the right side of the flat floor inductor; The first lower infrared module is correspondingly arranged directly below the first upper infrared module; The first upper infrared module transmits and receives a first infrared signal, and the first lower infrared module transmits and receives a second infrared signal. The second upper infrared module includes a second upper infrared transmitting module 320 located on the left side of the flat floor inductor and a second upper infrared receiving module 330 located on the right side of the flat floor inductor; The second lower infrared module is correspondingly arranged directly below the second upper infrared module; The second upper infrared module transmits and receives a third infrared signal, and the second lower infrared module transmits and receives a fourth infrared signal.

[0037] When the elevator is in normal operation, the flat floor inductor passes through the light blocking plate 340 of the floor. When the first upper infrared module is blocked, the second upper infrared module at the same horizontal height as the first upper infrared module is also blocked. Therefore, the first infrared signal and the third infrared signal are interrupted; When the elevator moves upward, the first lower infrared module is blocked, and the second lower infrared module at the same horizontal height as the first lower infrared module is also blocked. Therefore, the second infrared signal and the fourth infrared signal are interrupted; The signal processing module controls the output of the corresponding switch quantity module according to the interruption situation of the infrared signal.

[0038] Refer to Figure 4 , Figure 4 Schematic diagram of the flat floor inductor provided by some embodiments of the present application; The first upper infrared transmitting module 300 is located outside the flat floor inductor 100, and the second upper infrared transmitting module 320 is located inside the flat floor inductor. The first upper infrared transmitting module and the second upper infrared transmitting module are at the same horizontal height. The first upper infrared transmitting module is located above the first lower infrared transmitting module, and the second upper infrared transmitting module is located above the second lower infrared transmitting module. When the elevator car passes through the flat floor inductor, all infrared signals of the infrared transceiver module will be interrupted at different times, and the interruption times of several upper infrared modules are the same, and the interruption times of several lower infrared modules are the same.

[0039] It should be noted that since the first upper infrared module and the second upper infrared module are at the same horizontal height, when one upper infrared module is blocked, the second upper infrared module should also be blocked simultaneously. When the elevator is in normal operation, if it is detected that the first infrared signal of the first upper infrared module is interrupted and the second infrared signal of the first lower infrared module is interrupted, it can be explained that the flat floor inductor passes through the light blocking plate of the floor at this time, and then the second upper infrared module should also be blocked. However, if it is detected that the first infrared signal and the second infrared signal are interrupted, and the third infrared signal emitted by the second upper infrared module is not interrupted, it means that the second upper infrared module is faulty and the interruption of the infrared signal cannot be detected when blocked by the light blocking plate.

[0040] It should be noted that when the elevator is running normally and the flat layer inductor leaves the light shielding plate of the floor, the signal processing module should be able to detect that the first infrared signal, the second infrared signal, and the third infrared signal all return to normal reception. However, if in this case, it is detected that the first infrared signal and the second infrared signal are not interrupted, and the third infrared signal is interrupted, it indicates that the second upper infrared module is faulty, and signal interruption occurs even without the light shielding plate blocking.

[0041] Refer to Figure 5 , Figure 5 is a flowchart of a signal processing method for a flat layer inductor provided in some embodiments of the present application; the method includes but is not limited to steps S500 to step S510.

[0042] Step S500, when the first infrared signal of the first upper infrared module in the flat layer inductor is interrupted and / or the second infrared signal of the first lower infrared module is interrupted, control the flat layer inductor to output a first switching value.

[0043] Specifically, as described above, in the embodiments of the present application, several upper infrared modules and the same number of lower infrared modules are divided into a group, and each group corresponds to the output of one switching value. The first upper infrared module and the first lower infrared module can form a group. When the elevator car travels to the position of the flat layer inductor, the first upper infrared module and the first lower infrared module will be blocked in a certain order, then both the first infrared signal of the first upper infrared module and the second infrared signal of the first lower infrared module will be interrupted. When the signal processing module detects the interruption of the infrared signal, it controls the first switching value module to output the first switching value.

[0044] It should be noted that when the elevator is running normally and the flat layer inductor passes through the light shielding plate of the floor, the signal processing module can only detect that the first infrared signal is interrupted and detects that the second infrared signal is not interrupted, which indicates that the first lower infrared module is faulty, resulting in the signal processing module not detecting the interruption of the infrared signal when the light shielding plate blocks. In this group, the first upper infrared module works normally and the first lower infrared module is faulty. The signal processing module can still control the output of the first switching value according to the interruption situation of the first infrared signal. Since there is at least 1 upper infrared module and 1 lower infrared module in a group, and each group corresponds to the output of one switching value, as long as there are still normally working infrared modules in a group, this group can normally control the output of the switching value, improving the reliability of the switching value control module and effectively ensuring the safe operation of the elevator.

[0045] It should be noted that when the elevator is running normally and the flat layer inductor leaves the light blocking plate of the floor, the signal processing module should be able to detect that both the first infrared signal and the second infrared signal return to normal reception. However, if in this case the signal processing module detects that the first infrared signal is interrupted and the second infrared signal is not interrupted, it means that the first upper infrared module fails and the signal is interrupted even without the light blocking plate. Similarly, in this group, the signal processing module can still control the output of the first digital quantity according to the interruption situation of the second infrared signal.

[0046] Step S510: Determine the running direction of the elevator according to the first moment when the first infrared signal is interrupted and the second moment when the second infrared signal is interrupted.

[0047] Specifically, in the embodiment of the present application, the upper infrared module is located above the lower infrared module. During the operation of the elevator, the flat layer inductor will pass through the light blocking plate of the floor, and the light blocking plate blocks the infrared transceiver module, causing the infrared signal to be interrupted. Due to the different running directions of the elevator, the upper infrared module and the lower infrared module will be blocked in different orders. The first upper infrared module transmits and receives the first infrared signal, and the first lower infrared module transmits and receives the second infrared signal. When the first infrared signal is interrupted, the signal processing module records the first moment; when the second infrared signal is interrupted, the signal processing module records the second moment. If the first moment is earlier than the second moment, it means that the first upper infrared module is blocked first and the first lower infrared module is blocked later, proving that the elevator is in the upward state at this time. Similarly, if the first moment is later than the second moment, it proves that the elevator is in the downward state at this time.

[0048] It should be noted that when at least one of the first upper infrared module and the first lower infrared module fails, the information processing module cannot judge the running direction of the elevator according to the first signal and the second signal. In this case, if there are multiple upper infrared modules and the same number of lower infrared modules in a group, the interruption situation of the infrared signals of the normally working infrared modules is used for judgment. One pair or multiple pairs of upper and lower corresponding infrared modules in the flat layer inductor can be used to judge the running direction of the elevator.

[0049] Refer to Figure 6 , Figure 6 is the logic diagram of the infrared signal interruption situation and floor calculation provided by some embodiments of the present application; specifically, the signal processing module communicates with the elevator controller through the communication module, obtains data such as the floor number and terminal station of the elevator, and sends data such as the recorded floor number and fault information to the elevator controller. When initially powered on, the flat layer inductor initializes when detecting that the elevator is at the terminal station, sets the floor number to the value of the terminal station position, and determines the running direction of the elevator according to step S510 during the running state of the elevator. As Figure 6As shown, status 600, status 610, and status 620 represent the running direction of the elevator. Status 600 indicates that the elevator is going up, status 610 indicates that the elevator is staying (the elevator is neither going up nor going down), and status 620 indicates that the elevator is going down. Status 630 and status 640 represent the interruption situation of the upper infrared signal of the upper infrared module. Status 630 indicates that the upper infrared signal is not interrupted, and status 640 indicates that the upper infrared signal is interrupted; status 650 and status 660 represent the interruption situation of the lower infrared signal of the lower infrared module. Status 650 indicates that the lower infrared signal is not interrupted, and status 660 indicates that the lower infrared signal is interrupted. As Figure 6 shown, when the elevator is in status 600, that is, the elevator is going up, the upper infrared signal sent by the upper infrared module is interrupted first, and the lower infrared signal sent by the lower infrared module is interrupted later, then it can be determined that the elevator is currently in the upward state. Status 670, status 680, and status 690 represent the floor numbers of the elevator. Status 670 indicates that the elevator is at the specified starting floor. Representing the specified starting floor as N, then status 680 indicates that the elevator is on the N + 1 floor, and status 690 is on the N + 2 floor. When it is determined that the elevator is going up, the current floor number is incremented by 1; similarly, when it is determined that the elevator is going down, the current floor number is decremented by 1. The elevator floor number can be recorded in the storage module and sent to the leveling sensor by the elevator controller during elevator floor height learning.

[0050] The following describes the process of elevator operation in combination with the embodiments of the present application: When the elevator is initially powered on, the leveling sensor communicates with the elevator controller through the communication module and sends a secret key to the elevator controller. When the elevator controller determines that the leveling sensor is a legal device, the elevator starts to operate normally. The leveling sensor is initialized, and the number of floors stored in the storage module is set to the value of the terminal station position. The infrared transceiver module uses a time-sharing output method to send modulated infrared signals of different frequencies to avoid interference from external light and crosstalk of bypass infrared signals. When the elevator ascends, the leveling sensor passes through the light-blocking plate on the floor, and the infrared transceiver module is blocked. The first upper infrared module is blocked, and at the same time, the second upper infrared is blocked, and the first signal and the third signal are interrupted simultaneously. The signal processing module controls the output of one switching quantity according to the interruption of the first signal and controls the output of another switching quantity according to the interruption of the third signal. At the same time, the indicator lights corresponding to these two switching quantities in the status indication module flash. Subsequently, the elevator continues to ascend. The first lower infrared module and the second lower infrared module are blocked, but the signal processing module only detects the interruption of the second signal and does not detect the interruption of the fourth signal. It is determined that the second lower infrared module fails, and the indicator light corresponding to the second lower infrared module in the status indication module flashes to indicate a failure. The interruption of the third signal and the interruption of the fourth signal jointly correspond to one switching quantity. Therefore, the failure of the second lower infrared module does not affect the output of the corresponding switching quantity. During the operation of the elevator, in case of a sudden power failure, the power supply switching module in the leveling sensor switches the power supply of the leveling sensor from the normal power supply to the backup power supply, and the elevator can continue to record the current floor number. When the elevator enters the standby mode, the leveling sensor also enters the standby mode, turns off the switching quantity module and the status display module, and reduces the infrared transceiver frequency and the communication frequency to achieve the purpose of reducing power consumption. When the elevator resumes normal operation, it sends the normal operation mode to the leveling sensor, and the leveling sensor resumes normal operation.
