The light detection module comprises: the brightness detection unit can adopt photoelectric sensors, cameras and other optical state detectors and is used for detecting the brightness state of the optical identification piece on the floor where the elevator car is located and generating a detection signal, and the detection signal can be considered to reflect the brightness state of the detected optical identification piece.

(3) And the main control module is used for analyzing the detection signal and determining the current floor number. The information reflecting the brightness state can be obtained by analyzing the detection signal, and the floor (number) corresponding to the brightness state, namely the current floor number, is obtained based on the information, so that the detection of the elevator position is completed. Preferably, the main control module can also send the current floor number to the background server in a wireless/wired mode, the property can timely master the current position of the elevator car by accessing the background server, the background server can also be in communication connection with mobile terminals such as a mobile phone, a user can remotely obtain the current floor number through the mobile phone, and the current position of the elevator car can be timely known even when an elevator circuit fails. The system is independent of a floor monitoring system provided by an elevator manufacturer, and the elevator monitoring system can run normally even if the elevator fails, so that the elevator monitoring system is beneficial to the complete and effective management of a property owner on the elevator system.

Preferably, the main control module can be arranged in the elevator car, and specifically comprises: the processor is used for receiving and processing data and can adopt the existing chips such as STM32F1 series chips and the like; the acquisition circuit and the photoelectric coupler are used, because the output signal voltage of the photoelectric sensor and other devices is not matched with the IO port voltage of the processor (STM 32F1 series chips are used), the acquisition circuit is required to be arranged for conversion, and the photoelectric coupler is used for isolation.

In addition, in some embodiments of the invention, the elevator floor monitoring system further comprises a display board module arranged in the elevator car, the main control module can transmit data to the display board module in a mode of UART, SPI, IIC and the like, and the UART is taken as an example, the transmission baud rate can be set to be 115200, the transmission data length can be set to be 8, the stop bit can be transmitted in a mode of data, 1 bit can be transmitted, parity check is not used, and the like.

One of the preferred embodiments of the present invention is as follows:

the first embodiment is as follows:

floor number	Optical identification member
		A layer of	Non-bright
Two layers	Has bright color

TABLE 1

The elevator comprises a floor and optical identification relation table shown in table 1, the number of the buildings is two, identification modules are arranged in corresponding positions of one floor and two floors in an elevator shaft respectively, each identification module comprises an optical identification piece, the optical identification piece arranged on the one floor can not reflect light or emit light, the optical identification piece arranged on the two floors can possibly emit light or reflect light, and a light detection module on an elevator car is provided with a photoelectric sensor. When the elevator car is at one floor, the detected optical identification piece is not bright, the photoelectric sensor outputs a high-level signal and the high-level signal is received by the main control module, and the main control module analyzes the signal based on the corresponding relation between the light-emitting state and the floor in the table 1 to determine that the current floor number is one floor; when the elevator car is in the second floor, the detected optical identification piece is bright, the photoelectric sensor outputs a low-level signal and the low-level signal is received by the main control module, and the main control module analyzes the signal based on the corresponding relation between the luminous state and the floor shown in the table 1 to determine that the current floor number is the second floor.

In addition, for the case that some floors are more, the identification module can comprise the same number of optical identification pieces as the floors, and the photoelectric sensors also have the same number as the optical identification pieces and can detect the light states of the optical identification pieces in a one-to-one correspondence manner. In the system, incremental floor numbers are corresponded by incremental bright optical identification pieces, for example, one layer is provided with one bright optical identification piece, the second layer is provided with two bright optical identification pieces, the process is analogized in sequence, the main control module carries out statistics on received detection signals to judge the number of the bright optical identification pieces corresponding to the current position of the elevator car, and the current floor is determined based on the number and the corresponding floor relation, so that the monitoring system disclosed by the invention can be suitable for an elevator system with more floors of a building.

As can be seen from the first embodiment, the present invention is suitable for elevator systems with multiple floors, but the number of the light identification members and the light detection units needs to be increased proportionally with the increasing number of floors, which results in increasing the implementation cost and the operation workload of the main control module in some cases with particularly large number of floors. Therefore, the present invention further provides other embodiments, specifically, the identification module includes a plurality of optical identification members having a bit sequence relationship, the identification module of the plurality of optical identification members is suitable for a situation with a large number of floors, and the specific bit sequence relationship may be preset according to an actual situation. The brightness detection module comprises a plurality of brightness detection units, each brightness detection unit correspondingly detects one optical identification piece, namely, each brightness detection unit in the brightness detection module can respectively detect the brightness states of the plurality of optical identification pieces with a bit sequence relation so as to generate the detection signal with a signal bit sequence, and the signal bit sequence corresponds to the bit sequence relation of the optical identification pieces. And the main control module is used for determining the current floor number according to the detection signal and the signal bit sequence corresponding to the detection signal. The elevator floor monitoring can be completed by adopting fewer optical identification pieces and optical detection units through setting the optical identification piece bit sequence and the signal bit sequence of the detection signal, so that the implementation cost is saved, and the operation workload of the main control module is reduced. The preferred embodiment is as follows:

example two:

floor number	Optical identification member A	Optical identification member B	Optical identification member C
				Negative one layer	Has bright color	Has bright color	Has bright color
A layer of	Non-bright	Non-bright	Has bright color
				Two layers	Non-bright	Has bright color	Non-bright
Three layers	Has bright color	Non-bright	Non-bright
				Four layers	Non-bright	Non-bright	Non-bright

TABLE 2

As shown in table 2, there are five floors and light identifiers, each floor of the elevator shaft is provided with three light identifiers, the light status corresponding to the light identifiers of each floor can be randomly assigned, but it should be ensured that the light status is not repeated, the position sequence relationship is represented by A, B, C, when the elevator car stops at any floor, the three photoelectric sensors of the light detection module can correspond to the light identifiers A, B, C one by one, and further obtain the detection signals with corresponding signal position sequences, for example, when the elevator car stops at one floor, the detection signals with signal position sequences generated by the light detection module are high level signals-low level signals (which can be represented as 1-1-0), the main control module receives the group of signals and analyzes the signals to obtain the light status of the light identifiers of the current floor, and determines the current floor where the elevator car is located as one floor based on the floor relationship reflected in table 2. For a five-layer building, five optical identification pieces are usually required to be arranged to realize floor monitoring, and in the embodiment, only three optical identification pieces are adopted, and more floors can be corresponding to the building through the combination of different light states and position sequence relations, so that the implementation cost is saved, and the operation workload of the main control module is reduced.

It should be noted that the present embodiment adopts a light/no light manner to distinguish the light state, and other existing manners may also be adopted to distinguish the light state, for example, the light identifier A, B, C emits red, yellow and blue light respectively, and the corresponding light detection device can generate different detection signals according to the detected lights with different colors; alternatively, the light identifiers A, B, C emit lights with different intensities, and the corresponding light intensity detecting devices can generate different detecting signals according to the detected light intensities. Not to be considered as examples herein, subject to space.

In some embodiments of the present invention including the first and second embodiments, the optical identifier is: specifically, as shown in fig. 2 and 3, a reflective layer is arranged on the surface of the light-emitting member 1 and used for reflecting light of the photoelectric sensor and enabling the light to generate a low-level signal, a dark light layer is arranged on the surface of the non-light member 2, light emitted by a light source of the photoelectric sensor cannot be reflected after being irradiated on the dark light layer, and the photoelectric sensor generates a high-level signal. Light sources such as LEDs can also be used as the light identification part, namely the light part 1 when the light identification part is turned on, and the non-light part 2 when the light identification part is turned off. In the identification module, the corresponding floors are reflected by the optical identification pieces in different brightness states, namely, the identification module is positioned on the floors and the optical pieces 1 and the non-optical pieces 2 in different brightness states are regularly arranged according to the preset bit sequence.

In the embodiment, the light state is represented by the presence or absence of light of the light identification member, and besides, the light state can be represented by the difference of brightness, color and the like, which is not illustrated herein.

It should be noted that, for the preferred embodiments including the above embodiments, since the optical identifier having the bit sequence relationship has two states of light and no light, the detection signal can be expressed as "0" and "1" of binary numbers, that is, each binary number consisting of "0" and "1" can correspond to one floor, so that the maximum number of floors (the sum of the above-ground number of floors and the below-ground number of floors) to which the optical identifier can be applied can be directly determined by the number of optical identifiers included in the identification module, and at least the number of optical identifiers and light detection units are required for the building in which the system is to be implemented. For example, a binary number of three digits can express 8 digits (000 to 111) at most, that is, an identification module using three optical identification members can be adapted to a building with eight floors (the sum of the above-ground and underground floors) at most. In table 2, the presence and absence of light can be represented by 0 and 1.

In some embodiments of the invention, in the identification module, the number of light identifications is the same as the number of digits of the binary expression parameter of the total number of floors reachable by the elevator car. In the computer field, the high level is usually represented by the number "1", the low level is usually represented by the number "0", therefore can arrange the detected signal according to the signal bit sequence and form a binary number, specifically, the bit sequence relation of the digit of the binary number is directly adopted to correspond to the bit sequence and the signal bit sequence of the optical identification member, the main control module can directly obtain the binary expression corresponding to the current floor number by analyzing the detected signal and arranging according to the signal bit sequence, then directly convert to the decimal number and correspondingly adjust to be the current floor number, can obtain the conclusion (such as the above-mentioned table 1 and table 2) without comparing the relation of the light state and the floor number, and further reduce the operation amount. The preferred embodiment is as follows:

example three:

TABLE 3

As shown in the table of the relationship between the binary expression parameter and the floor shown in table 3, three digits of the binary expression parameter correspond to the detection signals with signal bit sequences generated by the three photosensors A, B, C, respectively, and when the photosensors detect that the optical identifier is an optical identifier, the detection signals are "0", otherwise, the detection signals are "1". For example, when the elevator car stops to a sixth floor, the optical identification member of the main control module is mainly composed of an optical member 1 and a non-optical member 2 as shown in fig. 2, and a reflective layer capable of reflecting light is arranged on the surface of the optical member 1. The main control module obtains that the binary expression parameter corresponding to the detection signal is 101, converts 101 into a decimal number of 5, but the binary expression parameter corresponding to one floor is set as a number 0, namely, the difference value between all floor numbers and the binary expression parameter is always 1, so that the parameter obtained by conversion needs to be added with 1 to obtain that the current floor number is 6, although the decimal number obtained by conversion is adjusted in a small amplitude, the corresponding relation between the detection signal and the floor, which is shown in the table 2, does not need to be considered, the operation workload is reduced, and the operation speed is improved. Preferably, one floor can be set to be 0001, so that the decimal number converted by the binary expression parameters is the current floor number per se, adjustment is not needed, and the calculation amount is further reduced.

In addition, for the case that the building has underground floors, the number converted into decimal number is actually the position relative to the total number of floors, the number of the underground floors can be preset, and the difference between the obtained total number of floors and the number of the underground floors can be calculated to obtain the current number of floors. It is worth mentioning that if the difference is 0, it is not that the elevator car is at the 0 th floor, and the main control module should further process and output the result as: the output should be-1, i.e., minus one floor; if the difference is-1, the output should be-2, i.e. minus two layers, and so on, and this document does not exemplify any more.

In some embodiments of the invention, the elevator floor monitoring system further comprises: the positive and negative floor marking pieces arranged in the elevator shaft can have the same structure/structure as the light marking pieces, the light states of the positive and negative floor marking pieces are determined based on the position relation of the floor where the positive and negative floor marking pieces are located relative to the ground, and preferably, the positive and negative floor marking pieces can be the light-emitting pieces or the non-light-emitting pieces, so that the positive and negative floor marking pieces have different light-emitting states. The elevator floor monitoring system further comprises: and the positive and negative floor detection unit is arranged on the elevator car and used for detecting the light state of the positive and negative floor identification piece corresponding to the position of the elevator car so as to obtain positive and negative floor signals. The main control module is used for analyzing the detection signal and the positive and negative floor signals and determining the current floor number, namely the main control module obtains the floor number by analyzing the detection signal, but the floor number may be an overground floor or an underground floor, so the main control module also needs to analyze the positive and negative floor signals and further determines that the floor is positioned on the ground or underground, and finally the accurate current floor number is obtained.

For buildings with more underground floors, the invention can further reduce the number of the light identification parts in the display module and the light detection units in the light detection module by the scheme. The following examples are given in detail.

Example four:

floor number	Positive and negative floor signal/binary expression parameter
		Negative one layer	1/001
Negative two layers	1/010
		……	……
Negative seven layers	1/111
		A layer of	0/001
Two layers	0/010
		……	……
Seven layers	0/111

TABLE 4

As shown in table 4, the building has 14 floors, which includes 7 floors above ground and 7 floors below ground, the identification module of each floor includes three optical identification members with a sequence relationship and a positive and negative floor identification member, the positive and negative floor identification member can be a light member and a non-light member according to the position relative to the ground, the elevator car is provided with four photoelectric sensors, one of which is a positive and negative floor detection unit for detecting the positive and negative floor identification members, and three of which is a brightness detection unit for respectively detecting the optical identification members and generating detection signals with signal sequences, the three detection signals respectively correspond to three digits of binary expression parameters, wherein the sequence of the floor optical identification members with the same absolute value of the floor number has the same brightness state, and therefore the detection signals generated by corresponding detection are also the same, at this time, the main control module analyzes the detection signals and converts the obtained binary expression parameters into decimal numbers, the current floor number corresponding to this number may be above ground and below ground, and therefore needs to be further determined in conjunction with positive and negative floor indicators. When the main controller receives the positive and negative floor signals generated by the positive and negative floor identification pieces, the positive and negative floor signals are analyzed, if the positive and negative floor signals are high level signals, the signals can be represented as 1, namely the decimal number is an underground floor; if the signal is a low level signal, it can be represented as 0, i.e. the decimal number is the floor above the ground.

Four identification pieces are arranged in the above mode, including a positive and negative floor identification piece 3 and three optical identification pieces, and the arrangement mode can be as shown in fig. 3. The system can be adapted to buildings with 14 floors (including seven floors above ground and seven floors below ground) at most, and the main control module does not need to compare the relation between the light state and the floors, so that the calculation amount is reduced.
