Description
Technical Field
The invention belongs to the technical field of engineering machinery monitoring, and particularly relates to an engineering machinery Internet of things monitoring system and method based on a block chain.
Background
With the rapid development of information technology, the internet of everything technology (IoT) has entered various industries, and digitization is becoming a new engine for engineering machinery development. Because the price of engineering machinery equipment is high and the use frequency of a single engineering builder is low, in order to improve the utilization rate of the equipment and save the total amount of engineering investment, the equipment leasing mode is mainly used in the engineering industry.
With the gradual expansion of the rental market of the engineering machinery, certain rental risks exist for both renters: the method comprises the following steps that a renter uses the engineering machinery after renting, and some users with poor reputation often have the phenomena of intentionally damaging the machinery and using the machinery beyond the range; in addition, the phenomenon that the equipment is lost or stolen due to unfavorable monitoring of a user also exists, so that the interest of a renter is lost; the use method comprises the following steps: when the leased engineering machinery is external machinery, particularly large machinery or remote leased machinery, the mechanical performance can not be verified in time, and a leasing party with poor reputation rents the fault machinery and then claims the damage of the use party as the damage of the use party, so that the benefit loss of the use party is caused.
In order to solve the technical problems, a great deal of effort is made, and a chinese patent discloses an engineering machine afterloading internet-of-things monitoring system, publication number CN111435232B, which proposes to install a monitoring terminal on each engineering machine, then connect the monitoring terminal with a monitoring center and a mobile terminal in a pairing manner, set a use range in the monitoring center, identify and locate a position by the monitoring terminal to solve the problem that the user is out of range, and the monitoring terminals can communicate with each other, and when the long-distance transmission is invalid, can send short-distance wireless signals to other surrounding machines through a third transmission device, thereby eliminating a monitoring blind area and finding lost equipment. However, the foregoing solutions still have some drawbacks, for example, the above solutions must install a monitoring terminal on the rental device, and if the monitoring terminal is not installed, the claimed effect cannot be achieved, and when the monitoring mobile terminal is easily removed, the lost/stolen device cannot be retrieved. In addition, the above scheme does not really solve the problem of rental of the faulty machine, and although the initial performance check is mentioned, firstly, the monitoring terminal is mastered by the renter, is easy to be controlled by the renter, is easy to cheat, and is not fair to the user; secondly, the performance inspection can only inspect the operation performance, and can be used for inspecting whether the current operation of the equipment is good or not and cannot ensure whether the equipment has a fault before the equipment, and the fault place is easy to have a secondary fault if the processing place is not good, and can only be used for inspecting some basic performance information, so that the appearance cannot be inspected, the monitoring parts cannot be damaged and other problems cannot be solved.
The block chain is a technical scheme which does not depend on a third party and carries out storage, verification, transmission and communication of network data through self distributed nodes. The blockchain technology can enable participants to achieve consensus without any intervention of a third-party center, solves the problem of reliable transmission of trust and value at extremely low cost, and is mainly applied to the financial industry at present. In the field of engineering machinery, there is also a technology that proposes monitoring of engineering machinery based on a block chain, but at present, the utilization of the block chain is only limited in a traditional automatic recording manner of the block chain, that is, transmission data of each node in a monitoring system is automatically uploaded to the block chain, for example, a distributed monitoring system of engineering machinery based on the block chain disclosed in chinese patent, publication No. CN 112653770A.

The engineering machinery platform 1 records the number of the monitoring terminal 3 and binds the corresponding relation between the monitoring terminal 3 and the equipment.
Similarly, the monitoring terminal 3 comprises a monitoring controller, a power supply module, a positioning module, a wireless module and a storage module, and the monitoring terminal 3 is connected with the engineering machinery platform 1, the block chain platform 5 and the mobile terminal 2 through the wireless module.
