Description

Meter data remote acquisition device flexible and convenient to use Technical Field The invention relates to the technical field of meter data acquisition, in particular to a meter data remote acquisition device which is flexible and convenient to use. Background In the field of public resource metering of water, electricity, gas and the like, remote acquisition of meter data is a key link for realizing intelligent management of resources and improving operation and maintenance efficiency. The traditional meter data remote acquisition system generally comprises a front-end meter, a remote acquisition device, a concentrator and a background management platform, wherein the core acquisition process comprises the steps that the front-end meter acquires resource usage data of a user in real time, the data is transmitted to the nearby concentrator in a wired or wireless communication mode, the concentrator is used as a core node for data aggregation and forwarding and is responsible for receiving scattered data of a plurality of front-end meters, and after summarizing and sorting, the data is uploaded to the background management platform through a wide area network communication module (such as GPRS, NB-IoT, loRa and the like), so that remote monitoring, statistics and analysis of meter data by management personnel are finally realized. Therefore, the concentrator plays important roles of data aggregation, protocol conversion and remote communication connection in a remote acquisition system, and is core equipment for guaranteeing efficient and stable transmission of meter data. In order to ensure the normal operation of the concentrator and avoid the corrosion and the artificial damage of the concentrator caused by external environments (such as wind and rain, sand and dust and high temperature and low temperature), the existing concentrator is generally required to be installed in a special protection box body, and the protection box body provides the protection environment for sealing, dust prevention and impact prevention for the concentrator. However, due to the diversity of meter installation scenes (e.g., residential corridors, commercial buildings, outdoor greenbelts, remote villages, etc.), the installation heights and environmental positions of the concentrators and the protective cases are difficult to be uniformly fixed. In the actual installation process, in order to reduce the risk of damage to the concentrator and the protective box caused by malicious damage, theft or accidental touch, a constructor usually installs the concentrator and the protective box at a higher position, especially in outdoor open scenes (such as roadsides and green belts), and the installation height often exceeds the conventional operation range of a human body. The high-level installation mode can improve the safety of equipment to a certain extent, but brings a plurality of inconveniences to subsequent maintenance work, namely when communication faults, abnormal data transmission, accessory replacement or software upgrading and the like occur in the concentrator, maintenance personnel can reach an installation position to carry auxiliary tools such as a ladder, a lifting platform and the like to carry out operation, the labor intensity of the maintenance personnel is increased, the fault handling time is prolonged, the potential safety hazard of the lifting operation exists, meanwhile, the carrying and the carrying of the auxiliary tools also promote the maintenance cost, the convenience of the maintenance and the overhaul of the concentrator is greatly reduced, and the operation and maintenance efficiency of the whole remote acquisition system is further influenced. Disclosure of Invention In order to solve the technical problems, the invention provides the gauge data remote acquisition device which can be used flexibly and conveniently and has the advantages of both equipment protection safety and maintenance convenience. The invention relates to a meter data remote acquisition device which is flexible and convenient to use, comprising a box body, wherein a concentrator is arranged in the box body, an auxiliary clamping frame is arranged on the inner wall of the box body, a door plate with an observation window is arranged on the box body, and meanwhile, a wire inlet hole provided with a wire protection sleeve is arranged at the bottom end of the box body, and the meter data remote acquisition device further comprises: the four corner parts of the fixed frame are provided with through holes in a penetrating way, and the four through holes are matched with expansion bolts to fix the fixed frame on the mounting surface; the two connecting plates are respectively arranged at the left side and the right side of the bottom end of the side wall of the fixed frame facing the box body; The left side and the right side of the back middle part of the box body are respectively provided with a control board, expansion bracket co
