It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein.

Example one
Fig. 1 is a flowchart of a light curtain control method according to an embodiment of the present application, where a light curtain may include a light curtain transmitting TX end and a light curtain receiving RX end. The light curtain transmitting TX end is used for transmitting infrared signals, and the light curtain receiving RX end is used for receiving the infrared signals. The output signal of the light curtain to the elevator is generally generated by a light curtain receiving end, so the light curtain receiving end is a main working module, and the light curtain transmitting end mainly transmits related infrared signals according to the requirement of the light curtain receiving end. Based on this, the present embodiment can control the light curtain to select the corresponding function through the relevant operation mode.
The present embodiment may be applied to an optical curtain receiving RX end, as shown in fig. 1, and the present embodiment may include the following steps:
and step 110, receiving a first infrared signal sent by a light curtain transmitting end.
The first infrared signal may be a signal received by the light curtain receiving end, or may be a plurality of signals received within a time period, which is not limited in this embodiment.
And step 120, judging whether the first infrared signal is a function setting infrared signal, and if so, entering a function setting mode.
After the light curtain receiving end receives the first infrared signal, the first infrared signal can be analyzed, and whether the first infrared signal is a function setting signal or not is judged. In the implementation, the analysis may be performed in such a manner that if the first infrared signal is an infrared signal received for a period of time, the rule of the first infrared signal may be analyzed, and then it is determined whether the rule is consistent with the rule of the function setting signal according to the rule, and if so, the first infrared signal is indicated as the function setting signal. If the first infrared signal is an infrared signal received once, the relevant signal can be extracted from the information carried by the first infrared signal, and whether the first infrared signal is a function setting infrared signal is judged according to the extracted signal.
And if the first infrared signal is judged to be the function setting infrared signal, controlling the light curtain to enter a function setting mode, and setting a specific function of the light curtain in the entering function setting mode.
And step 130, receiving a second infrared signal sent by the light curtain transmitting end.
In the function setting mode, the light curtain receiving end continues to receive the infrared signal sent by the light curtain transmitting end, and for convenience of distinguishing, the infrared signal received in the function setting mode is referred to as a second infrared signal.
And 140, determining a function to be set corresponding to the second infrared signal.
In the function setting mode, one of the functions of the second infrared signal is to indicate a function to be set.
Similar to the first infrared signal, the second infrared signal may be a signal received by the light curtain receiving end, or may be a signal received multiple times within a time period, which is not limited in this embodiment.
Through the analysis of the second infrared signal, the function to be set indicated by the second infrared signal can be determined. In the implementation, the analysis may be performed in such a manner that if the second infrared signal is an infrared signal received for a period of time, a rule of the second infrared signal may be analyzed, and then it is determined whether the rule is consistent with a rule of a specific function according to the rule, and if so, it indicates that the function to be set corresponding to the second infrared signal is the specific function. If the second infrared signal is the infrared signal received once, the relevant signal can be extracted from the information carried by the second infrared signal, and the function to be set corresponding to the second infrared signal is determined according to the extracted signal.
And 150, performing corresponding function setting on the light curtain according to the function to be set.
After determining the function to be set according to the second infrared signal, the function setting of the function to be set can be performed on the light curtain.
In this embodiment, the light curtain receiving end judges whether to enter the function setting mode according to the received infrared signal, and after entering the function setting mode, determines to-be-set functions according to the received infrared signal, and then performs corresponding function setting in the light curtain according to the to-be-set functions. The whole process does not need to change the structure of the light curtain and increase the cost of the light curtain, thereby reducing the maintenance cost of the light curtain.
Example two
Fig. 2 is a flowchart of a light curtain control method according to a second embodiment of the present application, and this embodiment explains an analysis process of a segment of received infrared signals on the basis of the first embodiment.
As shown in fig. 3, the light curtain transmitting TX end and the light curtain receiving RX end are both connected to the door control board of the elevator door through power lines, and the door control board includes a relay connected to the light curtain transmitting end for powering on or powering off the light curtain transmitting end. The embodiment can further control the setting of the function of the light curtain by a method of controlling the power supply of the light curtain transmitting terminal. Specifically, the power supply of the TX end is controlled by the relay of the gate control board, and the power supply of the TX end is cut off according to a certain rule, so that the infrared signal of the TX end is transmitted according to a certain rule, and the RX end is connected to the infrared signal according to a certain rule, thereby completing the function setting of the RX end.
As shown in fig. 2, the present embodiment may include the following steps:
Specifically, after the elevator is powered on, when the light curtain works normally, the power supplies of the TX end and the RX end of the light curtain are supplied simultaneously, and at the moment, the TX end and the RX end of the light curtain work normally. The TX end sends infrared signals to the RX end, and the RX end receives the infrared signals.
In the normal working process of the light curtain TX end and the light curtain RX end, if the RX end does not receive the infrared signal sent by the TX end and does not receive the infrared signal for the first time, the RX end records the time length of not receiving the infrared signal. If the infrared signal sent by the TX end is continuously received within the set time length range, the RX end can judge that the function setting mode needs to be entered currently.
When the RX end determines that the function setting mode needs to be entered currently, the RX end may trace back the start time, and use a specified time length from the start time as a first required time length, where the first required time length is used to limit a range where a segment of infrared signals for analysis is located. It should be noted that the specified time period may be an empirical value, or may be determined according to actual requirements, which is not limited in this embodiment, for example, the specified time period is 8s.
In one implementation, the starting time may be a last unit time of a unit time at which the infrared signal transmitted by the TX end is not received for the first time. Wherein one unit time may be 1s. For example, if the unit time in which the infrared signal transmitted by the TX end is not received for the first time is the 2 nd s, the start time is the 1 st s. For another example, if the unit time in which the infrared signal transmitted by the TX end is not received for the first time is 14 th s, the starting time is 13 th s.
After the first required duration is determined, the infrared signals received within the first required duration may be used as the first infrared signals.
The infrared signal received in the first required time is used for controlling the relay to supply power to the light curtain TX end by the gate control board, so that the light curtain TX end sends the infrared signal to the light curtain RX end; and if the infrared signal is not received within the first required time, the control relay of the door control board is indicated to cut off the power of the TX end of the light curtain. For the gate board, the gate board may set a power waveform according to a pre-generated function, where the power waveform may include a high level and a low level, the high level is used to instruct the gate board to control the relay to supply power to the light curtain TX end, and the low level is used to instruct the gate board to control the relay to power off the light curtain TX end.
For example, as shown in an exemplary function setting power waveform diagram of fig. 4, a high level is used to instruct the gate control relay to supply power to the light curtain TX end, a low level is used to instruct the gate control relay to power off the light curtain TX end, a duration of each cell is a unit time, for example, 1s, and then a duration of the whole function setting power waveform is a specified duration, that is, a first required duration, for example, 8s. When a function setting mode needs to be entered, the gate control board can acquire the function setting power supply waveform shown in fig. 4, and control the relay action of the TX end according to the function setting power supply waveform, and after the TX end power supply is controlled, the infrared signal is sent according to the corresponding rule. For example, in fig. 4, the gate control board controls the relay to supply power to the TX end at the 1 st unit time, controls the relay to cut off power to the TX end at the 2 nd unit time, controls the relay to supply power to the TX end at the 3 rd unit time, controls the relay to cut off power to the TX end at the 4 th unit time, controls the relay to supply power to the TX end at the 5 th to 7 th unit times, and controls the relay to cut off power to the TX end at the 8 th unit time, so that the TX end respectively transmits infrared signals to the RX end at the 1 st, 3 th, 5 th to 7 th unit times, and does not transmit infrared signals to the RX end at the 2 nd, 4 th, 8 th unit times. That is, for the RX end, during the whole first required time period, the infrared signals are received at 1 st, 3 rd, 5 th to 7 th unit times, and the infrared signals are not received at 2 nd, 4 th and 8 th unit times.
In one implementation, the power waveforms acquired by the gate board for the function settings may be pre-stored in the gate board, for example, the power waveforms may be saved to a storage area of the gate board after being input by a relevant worker in an input interface provided by the gate board. Alternatively, the function setting power waveform may also be obtained by the gate board in real time, for example, the function setting power waveform may be obtained from an upstream device in real time, which is not limited in this embodiment.
It should be noted that, in order to avoid the situation of mistaken shielding, after the TX end and the RX end of the light curtain are powered on, when the function setting mode needs to be entered, the door control board of the elevator can control the elevator door to be kept closed, and the relay is controlled to supply power or cut off power to the TX end on the premise that the elevator door is closed.
After the light curtain RX receives the first infrared signal, it can be determined whether the first infrared signal is a function setting infrared signal, and the determining process refers to the description of steps 204-206.
In one implementation, the first received signal sequence may be represented in the form of a waveform. Specifically, the RX end uses a high level to describe that the infrared signal is received in a certain unit time, and uses a low level to describe that the infrared signal is not received in a certain unit time, according to whether each time sequence (i.e., each unit time) in the first required time length receives the infrared signal, thereby generating a received waveform. For example, in the above example, if the RX side receives the infrared signals at 1 st, 3 rd, 5 th to 7 th unit times and does not receive the infrared signals at 2 nd, 4 th, 8 th unit times, the shape of the received waveform drawn by the RX side is also the shape shown in fig. 4, and the received waveform is the first received signal sequence.
In another implementation, the first received signal sequence may also be represented in a binary string. Specifically, the RX end uses a binary value "1" to describe that the infrared signal is received in a certain unit time, and uses a binary value "0" to describe that the infrared signal is not received in a certain unit time, according to whether each time sequence (i.e., each unit time) in the first required time length receives the infrared signal, so as to generate a first received signal sequence. For example, in the above example, if the RX receives infrared signals in 1 st, 3 rd, 5 th to 7 th unit times and does not receive infrared signals in 2 nd, 4 th, 8 th unit times, the first received signal sequence generated by the RX is "10101110".
It should be noted that the representation of the first received signal sequence is not limited to the above two manners, and those skilled in the art may adopt other representation manners according to actual needs.
In implementation, a function setting signal sequence used as a reference standard may be stored in the RX end, and the function setting signal sequence may be stored in a storage area of the RX end after being input by a relevant worker in an input interface provided by the RX end of the light curtain. Alternatively, the function setting signal sequence may also be obtained by the RX end in real time, which is not limited in this embodiment.
To facilitate a more direct comparison, the representation of the first received signal sequence may coincide with the representation of the function setting signal sequence.
After the RX end obtains the first received signal sequence and the function setting signal sequence, the RX end can compare the first received signal sequence and the function setting signal sequence to determine whether the first received signal sequence and the function setting signal sequence are the same. If the first infrared signal is the function setting infrared signal, the light curtain can be controlled to enter the function setting mode, and step 207 is continuously executed. If the first infrared signal is different from the function setting infrared signal, the first infrared signal is judged not to be the function setting infrared signal, the first infrared signal can be omitted, and signal monitoring is continued.
In practice, after entering the function setting mode, the RX end may further send a function setting signal to the gate control board to inform the gate control board that the function setting can be started.
When the light curtain enters the function setting mode, the specified time length from the start of entering the function setting mode may be used as a second required time length, and the second required time length is used to limit the range of the section of infrared signal for analysis after the light curtain enters the function setting mode. For example, the timing at which the light curtain enters the function setting mode is taken as the start timing, and the specified time period (for example, 8 s) from the start timing is taken as the second required time period.
And step 208, taking the infrared signal received within the second required time period as a second infrared signal.
When the second required time period is determined, the infrared signals received within the second required time period may be used as the second infrared signals.
When the light curtain control relay is implemented, when the door control board receives a function setting signal sent by the light curtain, a power waveform of a specific function to be set can be obtained, and whether the relay is controlled to supply power to the TX end of the light curtain or not is judged according to the power waveform of the specific function, wherein the power waveform of the specific function can also comprise a high level and a low level, the high level is used for indicating the door control board to control the relay to supply power to the TX end of the light curtain, and the low level is used for indicating the door control board to control the relay to cut off the power of the TX end of the light curtain.
For example, as shown in an exemplary functional-specific power waveform diagram of fig. 5, a high level is used to instruct the gate control relay to supply power to the light curtain TX end, a low level is used to instruct the gate control relay to power off the light curtain TX end, the duration of each cell is a unit time, for example, 1s, and the duration of the whole power waveform is a specified duration, that is, a second required duration, for example, 8s. When a specific function needs to be set, the gate control board may obtain the power waveform of the specific function shown in fig. 5, and control the relay of the TX end to operate according to the power waveform of the specific function, and after the power of the TX end is controlled, the infrared signal is transmitted according to a corresponding rule. For example, in fig. 5, the gate board controls the relay to supply power to the TX end at the 1 st unit time, controls the relay to cut off power to the TX end at the 2 nd and 3 rd unit times, controls the relay to supply power to the TX end at the 4 th unit time, controls the relay to cut off power to the TX end at the 5 th unit time, controls the relay to supply power to the TX end at the 6 th and 7 th unit times, and controls the relay to cut off power to the TX end at the 8 th unit time, so that the TX end transmits the infrared signal to the RX end at the 1 st, 4 th, 6 th, and 7 th unit times, and does not transmit the infrared signal to the RX end at the 2 nd, 3 th, 5 th, and 8 th unit times, respectively. That is, for the RX end, during the whole second required time period, the infrared signals are received at 1 st, 4 th, 6 th and 7 th unit times, and no infrared signal is received at 2 nd, 3 rd, 5 th and 8 th unit times.
Referring to the manner of generating the first received signal sequence in step 204, the second received signal sequence may be represented by a received waveform, for example, in the example of fig. 5, the shape of the received waveform drawn by the RX end is also the shape shown in fig. 5. Alternatively, the second received signal sequence may also be represented in the form of a binary string, such as "10010110" in the example of fig. 5.
In implementation, functional signal sequences for a plurality of specified functions as reference standards may be stored in the RX side, and for easier direct comparison, the representation of the second received signal sequence may be consistent with the representation of the functional signal sequence of each specified function.
And step 211, matching the second received signal sequence with each functional signal sequence, and taking the designated function corresponding to the successfully matched functional signal sequence as the function to be set corresponding to the second infrared signal.
After the RX end obtains the second received signal sequence and the functional signal sequences of each designated function, the RX end may search for the second received signal sequence in the functional signal sequences of each designated function, and if a functional signal sequence identical to the second received signal sequence is found, the designated function corresponding to the identical functional signal sequence may be used as the function to be set. If the functional signal sequence which is the same as the second receiving signal sequence cannot be searched, the RX terminal sends a search failure notice to the gate control board, so that the gate control board carries out power supply control of the TX terminal again to set a desired function.
And 212, performing corresponding function setting on the light curtain according to the function to be set.
After the RX end determines the function to be set, the corresponding function may be set for the light curtain. The present embodiment does not limit the manner in which the RX end sets the corresponding function on the light curtain. For example, the RX end may write the function to be set in the function partition of the light curtain, or the RX end may turn on a switch of the function to be set in a preset function list of the light curtain.
In one embodiment, the method may further include the steps of:
checking whether the function is successfully set on the light curtain; if yes, exiting the function setting mode; if not, outputting a light curtain fault signal.
In one implementation, it may be verified whether the function was successfully set on the light curtain as follows:
after the RX side sets the function on the light curtain, it sends the function identifier of the function (when the RX side performs function matching in step 211, the function identifier of the function that is successfully matched can be obtained) to the gate control board. After receiving the function identifier, the gate control board compares the function identifier with a function identifier of a specific function to be set, if the function identifier is consistent with the function identifier, a setting success signal is returned to the RX end to inform the RX end that the function setting is successful, and after receiving the setting success signal, the RX end judges that the current function is successfully set on the light curtain and controls the light curtain to exit the function setting mode. If the two signals are not consistent, the gate control board returns a setting failure signal to the RX end, the RX end judges that the setting of the current function on the light curtain is failed after receiving the setting failure signal, and at the moment, the light curtain failure signal can be output so as to carry out function setting again or adopt other modes for carrying out function setting.
In another implementation, it can also be verified whether the function is successfully set on the light curtain as follows:

EXAMPLE III
Fig. 6 is a flowchart of a light curtain control method according to a third embodiment of the present application, and this embodiment explains an analysis process of a received primary infrared signal on the basis of the first embodiment.
In practice, an infrared emission hole array is arranged on a light curtain emission TX end, and each infrared emission hole in the infrared emission hole array is used for emitting infrared rays; an infrared receiving hole array is arranged on the light curtain receiving RX end, and each infrared receiving hole in the infrared receiving hole array is used for receiving an infrared signal; and the infrared emission hole array and the infrared receiving hole array are arranged in a one-to-one correspondence mode, namely, one infrared emission hole is provided with a unique corresponding infrared receiving hole.
In one implementation, as shown in FIG. 7, individual ones of the array of IR-emitting holes and the array of IR-receiving holes may be numbered, with the same number of IR-emitting holes having a one-to-one correspondence with the IR-receiving holes.
In this embodiment, the light curtain can be set to enter different functions by shielding different infrared emission holes and combining the operation of the elevator door.
As shown in fig. 6, the present embodiment may include the following steps:
When the method is realized, a user can trigger to enter a function setting mode through an interface provided by an elevator master control. Specifically, the function parameter table can be displayed for a user in an interactive interface of the elevator master control, the function parameter table can comprise a plurality of functional switches, when the user wants to set a certain function on the light curtain, the switch of the function can be turned on, and at the moment, the elevator master control can capture the operation of turning on the switch of the certain function by the user. Because the function setting in the light curtain needs to enter the function setting mode, the elevator master control can default the operation that the user starts the switch of a certain function to the operation that the user triggers to enter the function setting mode.
The interactive interface of the elevator master control can be displayed through a terminal at the elevator side or through other terminals, and the other terminals can comprise a mobile phone, a palm computer, a desktop computer, inspection equipment and the like.
When the elevator master control detects that the user triggers to enter the function setting mode, a signal for entering the function setting mode can be sent to the light curtain TX end and the light curtain RX end at the same time.
For the light curtain TX end, after receiving the signal of entering the function setting mode, the TX end sends a prompt to the operator, where the prompt needs to enter the function setting mode. After receiving the prompt, an operator cuts off the power supply to the light curtain, acquires a shielding schematic diagram entering a function setting mode, and then performs shielding operation on one or more infrared emission holes in the infrared emission hole array according to the shielding schematic diagram. The blocking operation may illustratively include an operation of attaching a barrier.
In implementation, the operator may obtain the occlusion schematic diagram entering the function setting mode by, but not limited to, the following method: one of the ways is that the operator obtains the occlusion diagram of entering the function setting mode from the elevator master control through interaction with the elevator master control. Another way may be: the operating personnel finds the shielding paster marked as entering the function setting mode from the plurality of shielding pasters, takes the shielding paster as a shielding schematic diagram, and then aligns and pastes the shielding paster in the infrared emission hole array.
Illustratively, the occlusion map includes an infrared emission hole indicating occlusion and an infrared emission hole not being occluded. For example, as shown in the occlusion diagram of fig. 8 for entering the function setting mode, the numbers 1, 2, and 5 of the black background are all numbers to be occluded, and the numbers of the other white backgrounds are numbers not to be occluded.
When the operator finishes the shielding operation on one or more infrared emission holes in the infrared emission hole array, the light curtain is powered on, and the elevator door is closed. After the elevator door is completely closed (the light curtain can judge whether the elevator door is completely closed through judging the received light intensity), the light curtain TX end sends an infrared signal, and the infrared ray sent by the shielded infrared emission hole is shielded by a shielding object, so that the infrared signal cannot reach the light curtain RX end and is received by the light curtain RX end.
For the light curtain RX end, after receiving the signal entering the function setting mode, it waits for the infrared signal from the TX end, and uses the first infrared signal received after receiving the signal entering the function setting mode as the first infrared signal. The first infrared signal is an infrared signal sent by the light curtain transmitting end after one or more infrared transmitting holes in the infrared transmitting hole array are shielded. For example, in fig. 8, since the infrared emission holes numbered 1, 2, 5, etc. are blocked, the first infrared signal received by the light curtain RX is the infrared signal emitted from the infrared emission hole numbered (3, 4, 6, \8230;).
And 302, determining a shielding number of the transmitting terminal according to the received first infrared signal.
For example, in the above example, the first infrared signal received by the light curtain RX end is the infrared signal transmitted from the infrared transmitting hole with the number (3, 4, 6, \ 8230;), and the light curtain RX end may use the number that is not received as the transmitting end shielding number, that is, the number (1, 2, 5, \\ 8230;) as the transmitting end shielding number.
When the function setting shielding number is implemented, the function setting shielding number used as a reference standard may be stored in the RX end, and the function setting shielding number may be stored in a storage area of the RX end after being input in an input interface provided by the RX end of the light curtain by a relevant worker. Or, the function setting blocking number may also be obtained by the RX end from the elevator master control, which is not limited in this embodiment.
After the RX end obtains the shielding number of the transmitting end and the function setting shielding number, the RX end can compare the transmitting end and the function setting shielding number to determine whether the transmitting end and the function setting shielding number are the same. If the first infrared signal is the function setting infrared signal, the light curtain can be controlled to enter the function setting mode, and step 304 is continuously executed. If the first infrared signal is different from the function setting infrared signal, the first infrared signal is judged not to be the function setting infrared signal, the first infrared signal can be ignored, and the signal monitoring is continued.
In practice, the light curtain can be reminded to the operator to enter the function setting mode through the indicator light of the light curtain, for example, the indicator light of the light curtain can be slowly flashed to remind the operator to enter the function setting mode.
And step 304, receiving a second infrared signal sent by the light curtain transmitting end.
After the light curtain enters the function setting mode, the infrared signal received after the light curtain enters the function setting mode can be used as a second infrared signal.
The first infrared signal is intended to control the light curtain to enter a function setting mode, and the second infrared signal is intended to make a setting of a specific function. Similar to the first infrared signal, the second infrared signal is also the infrared signal sent by the light curtain transmitting end after one or more infrared transmitting holes in the infrared transmitting hole array are shielded. The difference is that the first infrared signal is different from the second infrared signal in that the blocked infrared emission holes are different.
When the elevator is in the functional setting mode, the elevator door needs to be opened again, and the light curtain is powered off. Then, the operator may remove the previous shielding object covering the infrared emission holes, obtain a shielding schematic diagram of the function to be set (similar to the above-mentioned shielding schematic diagram of entering the function setting mode), and then perform shielding operation on one or more infrared emission holes in the infrared emission hole array according to the shielding schematic diagram. For example, as shown in the occlusion diagram of fig. 9 for setting a specific function, the lamps numbered 2, 4 and 6 of the black background are all the infrared emission holes to be occluded, and the other white background is numbered as the infrared emission holes not to be occluded.
When the shielding operation of one or more infrared emission holes in the infrared emission hole array is completed by an operator, power is supplied to the light curtain, and the elevator door is closed. When the elevator door is completely closed, the light curtain TX end sends out an infrared signal, and the infrared ray sent out by the shielded infrared emission hole is shielded by a shielding object, so that the infrared signal cannot reach the light curtain RX end and is received by the light curtain RX end.
And 305, determining a corresponding transmitting end shielding number according to the second infrared signal.
For the light curtain RX end, after receiving the second infrared signal, it may use the number that is not received as the transmitting end shielding number corresponding to the second infrared signal, that is, the number (2, 4, 6, \ 8230;) as the transmitting end shielding number.
And step 306, matching the shielding numbers of the transmitting terminal corresponding to the second infrared signal with the shielding numbers of a plurality of preset specified functions, and taking the specified functions successfully matched as functions to be set.
In implementation, the RX end may store a plurality of shielding numbers for a designated function as a reference standard, and after the RX end obtains the transmitting end shielding number corresponding to the second infrared signal, the transmitting end shielding number corresponding to the second infrared signal may be searched for in the shielding numbers of the designated function. If the transmitting end shielding number corresponding to the second infrared signal is found, the found designated function can be used as a function to be set. And if the transmitting end shielding number corresponding to the second infrared signal cannot be found, the RX end sends a finding failure notice to the elevator master control.
After the RX end determines the function to be set, the corresponding function may be set for the light curtain. In this embodiment, the manner of setting the corresponding function at the light curtain by the RX end is not limited. For example, the RX end may write the function to be set in the function partition of the light curtain, or the RX end may turn on a switch of the function to be set in a preset function list of the light curtain.
In practice, can remind operating personnel current function setting to accomplish through the pilot lamp of light curtain, for example, can remind the pilot lamp flash red light of light curtain.
In one embodiment, the method further comprises the following steps:
checking whether the function is successfully set on the light curtain; if yes, exiting the function setting mode; if not, outputting a light curtain fault signal.
When the elevator is realized, after the function setting is finished, the whole elevator can be powered off and then powered on again, and the light curtain is powered on. The RX side then sends the function identification of the currently set function to the elevator master. After receiving the function identifier, the elevator master control compares the function identifier with the function identifier of the specific function to be set, if the function identifier is consistent with the function identifier of the specific function to be set, a setting success signal is returned to the RX end to inform the RX end that the function setting is successful, and after receiving the setting success signal, the RX end judges that the current function is successfully set on the light curtain and controls the light curtain to exit the function setting mode. If the two are inconsistent then the elevator master control returns and sets up the failure signal for the RX end, then the RX end is received and is set up failure then to judge that current function is failed on the light curtain, can output light curtain fault signal this moment to in the follow-up function setting of carrying on again or adopt other modes to carry out the function setting.
In this embodiment, the mode through setting up the shelter in infrared emission hole makes the infrared signal's of light curtain transmission end sending present certain law to make the light curtain receiving terminal receive the signal of certain law, carry out the analysis through the infrared signal to certain law received, thereby accomplish the function setting to the light curtain, whole process need not to change the structure of light curtain, also need not to increase the cost of light curtain. Meanwhile, the whole process does not need to increase other elevator hardware, and the elevator can be directly set in a manual mode, so that the elevator is suitable for the condition that the function is set in the debugging stage.
