the method comprises the following steps: powering on a light curtain, and initializing the light curtain; the light curtain initialization comprises: initializing the MCU; initializing a sensor; initializing a communication module;
step two: the sensor collects a plurality of data and stores the data in a main data container;
step three: when the main data container accumulatively receives N data, transmitting the N data to a primary data container; n is a positive integer;
step four: carrying out variance operation on the N data of the first data container, and if the obtained result is greater than or equal to a preset value, transmitting the result to a database through the communication module; if the data is less than the preset value, all data is discarded.
Further, in the data acquisition method, when the fourth step is executed, the main data container continues to receive the data acquired by the sensor, and when N data are accumulatively received, the N data are transmitted to the secondary data container; carrying out variance operation on the N data of the second data container, and if the obtained result is greater than or equal to a preset value, transmitting the result to a database through the communication module; if the data is less than the preset value, all data is discarded.
Further, in the data acquisition method, the sensor includes a three-axis acceleration sensor.
Further, in the data acquisition method, the communication module is a narrowband internet of things.
Further, in the data acquisition method, the communication module is a global system for mobile communications.

Drawings
Fig. 1 is a flow chart of a data acquisition method according to the present invention.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "one" means not only "only one" but also a case of "more than one".
As shown in fig. 1, the present invention provides a data acquisition method, including the following steps:
the method comprises the following steps: powering on a light curtain, and initializing the light curtain; the light curtain initialization comprises: initializing the MCU; initializing a sensor; initializing a communication module;
in this step, the light curtain is loaded into the elevator and then powered up, and the light curtain enters the initialization process. In this embodiment, the sensor includes a three-axis acceleration sensor, and in other embodiments, the sensor may further include: a vibration sensor, a temperature and humidity sensor, etc.
Further, in this embodiment, the communication module employs a narrowband internet of Things (NB-IoT); in another embodiment of the present invention, the communication module employs a Global System for Mobile Communications (GSM).
Step two: the sensor collects a plurality of data and stores the data in a main data container;
step three: when the main data container accumulatively receives N data, transmitting the N data to a primary data container;
in this step, the primary data container is not immediately transmitted to the database upon receiving the data, but is uniformly transmitted to the database after accumulating to a certain amount. In this embodiment, N is 100, that is, when the main data container receives 100 accumulated data, the data will be transmitted to the first data container;
step four: carrying out variance operation on the N data of the first data container, and if the obtained result is greater than or equal to a preset value, transmitting the result to a database through the communication module; if the data is less than the preset value, all the data is discarded.
Specifically, in this embodiment, variance operation is performed on 100 data, if the obtained result is greater than or equal to 50, it is determined to be valid, and the result is transmitted to the database through the communication module, and if the obtained result is less than 50, the 100 data are discarded together.
Further, in the data acquisition method, when the fourth step is executed, the main data container continues to receive the data acquired by the sensor, and when N data are accumulatively received, the N data are transmitted to the secondary data container; performing method operation on the N data of the first data container, and if the obtained result is greater than or equal to a preset value, transmitting the result to a database through the communication module; if the data is less than the preset value, all data is discarded.
Furthermore, the second data container is set because when the first data container transmits data, if a network failure or transmission error occurs, subsequent data acquisition, reception and transmission are not affected. Similarly, if the first data container and the second data container are not completely transmitted, a third data container, a fourth data container, etc. can be established.
In conclusion, the elevator operation data can be acquired in real time without additionally installing an acquisition device and an acquisition system, and the method is convenient and rapid.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
