Description

Technical Field

[0001] The invention relates to the field of gas meters, and in particular to a mechanical gas meter state measurement alarm system. Background Art

[0002] From the outside of the gas meter, you can only see a digital roller in a small glass window. There are also seven digits on the roller, with the first four digits of the decimal point in black and the last three digits in red. The fuel people use for daily cooking has changed from conventional energy sources such as firewood and coal, which waste resources and cause serious pollution, to natural gas and coal gas, and even clean energy such as electricity. Here the gas meter will play its role. Its automatic accumulation function allows those who use natural gas or pipeline gas to easily know how much gas they have used, so that they can pay according to the cubic meters of gas consumed each month. The working principle of the mechanical gas meter is as follows: the gas enters the worm gear chamber through the inlet, the gas drives the worm gear to rotate, the rotation of the worm gear and the worm is transmitted to the pointer through the mechanical transmission structure, and the position of the pointer is the gas consumption.

[0003] However, under long-term use, especially for mechanical gas meters in external working environments, the surface shape may be standard when it leaves the factory, but at a certain point in time, due to accidental damage to external equipment or wind aging, the actual surface shape begins to deviate and deform, which may seriously affect the normal working performance of the mechanical gas meter. Summary of the invention

[0004] In order to solve the technical problems in related fields, the present invention provides a mechanical gas meter state measurement and alarm system. By adopting a state identification device with targeted design including a model building unit, a value acquisition unit and a state detection unit, an intelligent identification of the on-site deformation value corresponding to the dial of the mechanical gas meter is completed. The larger the on-site deformation value corresponding to the dial of the mechanical gas meter, the greater the deviation between the geometric shape of the entity corresponding to the dial of the mechanical gas meter and the standard geometric shape corresponding to the dial of the mechanical gas meter. Subsequently, a wireless notification device is used to package the received on-site deformation value corresponding to the dial of the mechanical gas meter and the positioning data of the mechanical gas meter and transmit them wirelessly to a remote meter monitoring server, thereby completing the distributed monitoring of the mechanical gas meters in the operating states of different positions one by one.

[0005] According to the present invention, a mechanical gas meter state measurement alarm system is provided, the system comprising:

[0006] an operation detection mechanism connected to the mechanical gas meter, and used to detect whether the mechanical gas meter is currently in an operating state, and to send a first detection signal when it is detected that the mechanical gas meter is currently in an operating state, and to send a second detection signal when it is detected that the mechanical gas meter is currently in a closed state;

[0007] A macro camera mechanism connected to the operation detection mechanism, and configured to perform a macro camera operation facing the dial of the mechanical gas meter upon receiving the first detection signal, so as to obtain and output a scene environment picture corresponding to the environment where the dial is located;

[0008] A multi-level optimization device, connected to the macro camera mechanism and comprising a primary optimization component, a secondary optimization component and a final optimization component, for sequentially performing arithmetic mean filtering processing, image content enhancement processing based on exponential transformation and Gaussian high-pass filtering processing on the received scene environment picture, so as to obtain and output a corresponding multi-level optimized image;

[0009] A state identification device is connected to the multi-level optimization device and includes a model shaping unit, a value collection unit and a state detection unit. The state detection unit is connected to the model shaping unit and the value collection unit respectively. The model shaping unit is used to establish a feedforward neural network after completing multiple learning. The state identification device is used to use the feedforward neural network after completing multiple learning to intelligently identify the on-site deformation value corresponding to the dial of the mechanical gas meter based on the curvature values ​​corresponding to each position on the edge of the imaging block of the mechanical gas meter's dial in the multi-level optimization image, the curvature values ​​corresponding to each position on the edge of the standard geometric shape corresponding to the mechanical gas meter's dial, and the area ratio of the imaging block of the mechanical gas meter's dial in the multi-level optimization image to the multi-level optimization image. The positions are evenly spaced on the corresponding edges. The larger the on-site deformation value corresponding to the dial of the mechanical gas meter, the greater the deviation between the geometric shape of the entity corresponding to the dial of the mechanical gas meter and the standard geometric shape corresponding to the dial of the mechanical gas meter;

[0010] A wireless notification device, connected to the state identification device, is used to package the received field deformation value corresponding to the dial of the mechanical gas meter and the positioning data of the mechanical gas meter and transmit them wirelessly to a remote meter monitoring server;

[0011] Among them, the multi-level optimization device is connected to the macro camera mechanism and includes a primary optimization component, a secondary optimization component and a final optimization component, which is used to perform arithmetic mean filtering processing, image content enhancement processing based on exponential transformation and Gaussian high-pass filtering processing on the received scene environment picture in sequence to obtain and output the corresponding multi-level optimized image, including: the primary optimization component, the secondary optimization component and the final optimization component respectively perform arithmetic mean filtering processing, image content enhancement processing based on exponential transformation and Gaussian high-pass filtering processing on the received picture data.

[0012] It can be seen that the present invention has at least the following three significant substantive features:

[0013] Firstly, a specially designed state identification device including a model shaping unit, a value collection unit and a state detection unit is used to complete the intelligent identification of the on-site deformation value corresponding to the dial of the mechanical gas meter. The larger the on-site deformation value corresponding to the dial of the mechanical gas meter, the greater the deviation between the geometric shape of the entity corresponding to the dial of the mechanical gas meter and the standard geometric shape corresponding to the dial of the mechanical gas meter.

[0014] Secondly: a wireless notification device is used to package the received on-site deformation value corresponding to the dial of the mechanical gas meter and the positioning data of the mechanical gas meter and transmit them wirelessly to a remote meter monitoring server, thereby completing the distributed monitoring of the mechanical gas meters in different operating states at different locations;

[0015] Again: a multi-level optimization device including a primary optimization component, a secondary optimization component and a final optimization component is used to sequentially perform arithmetic mean filtering processing, image content enhancement processing based on exponential transformation and targeted optimization processing of Gaussian high-pass filtering processing on the on-site environment picture corresponding to the environment where the monitored mechanical gas meter is located, so as to obtain a multi-level optimized image with higher image quality for subsequent intelligent identification of the dial status.

[0016] The mechanical gas meter state measurement alarm system of the present invention has reliable logic and stable operation. By using a state identification device designed specifically to realize intelligent identification of the on-site deformed value corresponding to the dial of the mechanical gas meter, and then using a wireless notification device to wirelessly transmit the on-site deformed value to a remote meter monitoring server, visual monitoring of the mechanical gas meter in operation is completed.
