Black box

Abstract

The invention discloses a black box. The black box has a compact main body structure, a small volume, light weight and good heat radiation. The black box is protected by multiple protection methods and thus shock-proof, electricity-proof and interference-proof capabilities are greatly improved. The black box is provided with an industrial grade main board, and can resist a high temperature and interference and continuously run for 24 hours. In a respect of data security, internal data of the black box can not be looked up without enough authority; and the black box has a safe locking function and thus an unauthorized user cannot read, copy and tamper any data of the black box without using a specialized unlocking tool. In a respect of network ensurance, in the case of routine network interruption of a station, the black box can communicate with a quality management system by a network communication module carried by the black box. In a respect of carrying convenience, if network and 3G signals do not exist in a stirring station, the black box needs to be regularly moved to an area where network signals exist so that index synchronization is realized. In a respect of intelligent protection, the black box can automatically shut down software and an operating system of its own when a power supply is interrupted accidentally, and can automatically start the operating system and the software when power is supplied again.

Description

technical field [0001] The utility model relates to an industrial-grade equipment, specifically, the utility model is an electronic instrument (black box for short) specially used in the ready-mixed concrete industry for transmitting and recording quality data and confidential data. Background technique [0002] Ready-mixed concrete is also called ready-mixed concrete. Its essence is to separate concrete, the main building material, from the production links of material preparation, mixing, transportation, and pouring, from the traditional on-site construction, and through highly specialized centralized mass production, it has become An independently accounted production of building materials. Because of its many benefits in ensuring project quality, reducing energy consumption, saving construction land, improving labor conditions, and reducing environmental pollution, it has been highly valued by relevant government departments. On October 16, 2003, the Ministry of Commerce...

Problems solved by technology

[0005] The inherent characteristics of concrete: there are many factors and links that affect the quality, and there are many random factors, so it is difficult to keep the quality of concrete in an effective and controlled state.

[0006] There is no effective method and means for pre-control of concrete quality, quality inspection and acceptance lag (generally 28 days), basically equal to "post-mortem autopsy", and losses are often unavoidable when problems are found
