In recent years, with the relevant national policies, dry mortar industry in our country got fast development, industry management departments of provinces and cities, and the related enterprise close cooperation, continuously grope for the different characteristics of industry development model. Mortar industry production, storage and transportation, the use of three main parts. Production and use of link aside, storage and transportation links as to undertake the production and use in the middle of the process, and is linked to the mortar production units and their direct user, the stand or fall of its management directly affects the production enterprise operating costs and user satisfaction. Slurry transportation itself is a very complicated process, not only including the transport vehicle management, include of slurry storage tank operation, the traditional slurry storage and transportation management major problems are as follows:
With mortar production units not timely access to the site can save material allowance information, unable to actively organize effective transport, lead to the often appear lack of material, leftover material, and so on and so forth, causing serious waste of transport resources and at the same time also affect the enthusiasm of the site using the mortar. Due to scheduling personnel transportation vehicles position, cannot be obtained in pilot roads are not ripe, sometimes appear the phenomenon of detours to prompt delivery. For drivers speeding and illegal discharge, the phenomenon such as private is available. These not only lead to increased transportation costs, at the same time also brought great potential safety hazard. Material storage tank weighing sensor is affected by the bad site environment, easy to damage, and the sensor once damaged, will be a direct result of weighing system can't normal measurement, need to maintenance in time, if the site feedback timely or maintenance personnel not timely arrangement, will seriously affect the user satisfaction. More certain mortar production enterprises in the region, often appear a site with multiple mortar factory supply, so often there will be a site to use other factory of mortar mortar, due to the site usage cannot be obtained, finally according to the actual usage dosage far less agreement. Mortar enterprises due to the site daily dosage situation cannot be obtained, can't make practical production and the sales plan in advance, the management level cannot be improved. Scattered, on the other hand, do as the management of the industry, the industry management and formulate the policy of industry process, need to know the production of dry mortar, usage and other industry data, on the basis data for decision making, and do the source of the data and scattered can only be reported by the enterprise by quarterly and yearly report, not only the authenticity of the data can't verify, and data tend to delay a long time. How to solve the above problem, we will in the first chapter introduces functional features.
1. Functional features
In order to solve the above problems, really dry mortar storage and transportation and improve the management level, my moon and by studying the development of science and technology group, ultimately through information technology, the dry mortar will store the real-time location information of container, mortar allowance information integration in the industry and the position of the vehicle information unified network office of management and business operation platform, and realized:
(1) when the mortar material storage tank absence, dry mortar in alarm system platform automatically, mortar production enterprises can take the initiative to contact the construction unit, ask to goods, organize production and transport in advance, completely solve the "cutting" and "leftover material" problem, improve the dry mortar logistics service timely.
(2) through the dry mortar system platform for the truck transportation process can be monitored, know the current vehicle position and speed information, such as judging vehicle unloading state, improve the efficiency of the use of vehicles. Through historical playback, overspeed alarm function, reduce or eliminate the occurrence of the phenomenon such as detours, reduce management costs.
(3) when there is abnormal material storage tank weighing sensor, automatic alarm, dry mortar system platform management staff in the office can be found that the failure of the sensor, and through the appropriate method, make the material storage tank under the condition of the lack of a sensor can still normal use in the short term, the maintenance personnel can arrange maintenance plan according to the needs of work, improve the efficiency of maintenance, reduce the maintenance cost, changed the past can only passively waiting for site service mode of service, enhanced customer service satisfaction.
(4) when there is a material storage tank weight increase, rather than the mortar factory vehicle loading, dry mortar system platform for illegal filling material alarm, prompt mortar factory attention, to some extent, it can put an end to the phenomenon of factory site to use other mortar mortar.
(5) dry mortar system platform automatically generated mortar filling material report, daily dosage of report, as an external settlement and reference of the internal production and sales plan. At the same time system platform for mortar factory provide the function of remote zero calibration and weight for weight, make the material storage tank calibration work can be done directly in the computer, reduce a lot of maintenance work.
