Problems solved by technology

In the specific implementation, due to the influence of negative factors such as weather, temperature and aging, the weighing data of the elevator obtained through the pressure sensor will deviate from the actual load data of the elevator, which will increase the risk of taking the elevator. For example, when the temperature is too high, The weighing data measured by the sensor is less than the actual load data of the elevator, and the elevator may be in a state of frequent overload operation, or even elevator failure, which increases the risk of users taking the elevator

Embodiment 1

[0060] figure 1 It is a flow chart of a detection method for an elevator load cell provided by an embodiment of the present invention. This embodiment is applicable to the detection of an elevator load cell. The method can be performed by a detection device for an elevator load cell. The elevator The detection device of the load cell can be realized by means of software and / or hardware. Specifically, such as figure 1 As shown, the detection of the elevator load cell specifically includes the following steps:

[0061] Step 110, acquire the load cell data of the elevator, and acquire the temperature data corresponding to the load sensor data.

[0062] In actual processing, the elevator load cell can be used to detect the weight of the bridge car of the elevator, and can generate corresponding load cell data. The load cell data can represent the load of the elevator collected by the load cell in the elevator, such as the weighing data collected by the load cell in the elevator...

Embodiment 2

[0106] On the basis of the above-mentioned embodiments, the implementation of the present invention also provides another detection method for elevator weighing sensors, which is applied to the main control equipment of elevators, such as image 3 As shown, the detection method of the elevator load cell can specifically include the following steps:

[0107] Step 310, after the elevator is out of service, determine whether the elevator bridge car is in an empty state according to the camera information.

[0108] Specifically, the elevator is usually equipped with a camera, so that the elevator bridge car can be photographed by the camera to generate corresponding camera information. The main control device of the elevator can judge whether there are passengers and objects left in the elevator bridge car by obtaining the camera information, so as to determine whether the elevator bridge car is in an empty state. If there are no passengers and objects left in the elevator bridge...

Embodiment 3

[0123] refer to Figure 4 , shows a structural block diagram of the detection device of the elevator weighing sensor in the embodiment of the present invention. The detection device of this elevator load cell specifically can comprise following module:

[0124] Elevator data acquisition module 410, used to acquire the load cell data of the elevator, and obtain the temperature data corresponding to the load cell data;

[0125] A reference data acquisition module 420, configured to acquire no-load reference data of the elevator according to the temperature data;

[0126] The data analysis module 430 is configured to perform data analysis according to the load cell data and the no-load reference data, and obtain the detection result of the load cell of the elevator.

[0127] On the basis of the foregoing embodiments, optionally, the elevator data acquisition module 410 may include the following submodules:

[0128] The sample storage time determination submodule is used to det...

Abstract

The embodiment of the invention discloses a detection method for a weighing sensor of an elevator and related equipment and relates to the technical field of elevators. The method comprises the stepsof acquiring data of the weighing sensor of the elevator, and acquiring temperature data corresponding to the data of the weighing sensor; acquiring non-load reference data of the elevator according to the temperature data; conducting data analysis according to the data of the weighing sensor and the no-load reference data, and obtaining a detection result of the weighing sensor of the elevator. According to the detection method, the weighing sensor of the elevator is automatically detected, and therefore pre-judgement can be performed in advance before a failure occurs, that is to say, the problem can be solved that due to large deviation of the weighing data obtained through measurement of the weighing sensor and the actual load data of the elevator, the failure of the elevator is caused. The safety of a user when taking the elevator is guaranteed, and the failure occurrence probability of the elevator is lowered.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a detection method of an elevator weighing sensor and related equipment. Background technique [0002] With the rapid development of science and technology, elevators are becoming more and more popular, which brings great convenience to people's life, work and study. [0003] At present, most elevators usually use pressure sensors to detect the actual load of the elevator to obtain the weighing data of the elevator, so as to determine the load weight of the elevator bridge car according to the weighing data. In the specific implementation, due to the influence of negative factors such as weather, temperature and aging, the weighing data of the elevator obtained through the pressure sensor will deviate from the actual load data of the elevator, which will increase the risk of taking the elevator. For example, when the temperature is too high, The weighing data measured by the s...
