Construction site environment monitoring method and system based on block chain technology

Abstract

The invention belongs to the related technical field of construction supervision, and discloses a construction site environment monitoring method and system based on a block chain technology, and the method comprises the steps: setting a block chain network with a data chain and a transaction chain, and arranging a smart contract on the data chain and the transaction chain; the Internet of Things terminal sends the collected data to the data chain, and if abnormal values and key factors in the data meet automatic execution conditions, performance calculation is carried out; the construction party fills in the payment application form through the transaction chain and digitally signs the payment application form, and lock chain codes are set for the payment application form in a preset sequence; and the supervisor or the constructor sets an unlocking chain code according to the performance calculation result, obtains two oracle results based on a dual-stack evaluation mechanism, and executes payment operation if the two oracle results pass verification. According to the invention, coupling management of data, performance and payment can be realized on the premise of ensuring data reliability, tracing reliability and transmission security, and manpower and material resources are greatly saved.

Description

technical field [0001] The invention belongs to the technical field related to construction supervision, and more particularly, relates to a method and system for environmental monitoring of construction sites based on blockchain technology. Background technique [0002] The rapid development of the construction industry plays an important role in the national economy. However, fragmented and extensive construction methods have brought about a series of problems, one of which is serious environmental pollution. There are several problems in the current construction environmental management. First, the construction party has insufficient understanding of environmental costs and cannot pay them in time. Second, the construction party lacks an internal control mechanism. The environmental protection costs are included in the cost of safety and civilized measures. From the top to the front line of the project operation, the management process between various business departments...

Problems solved by technology

[0002] The rapid development of the construction industry occupies a pivotal position in the national economy. However, fragmented and extensive construction methods have brought about a series of problems, and serious environmental pollution is one of them.

There are several problems in the current construction environment management. First, the construction party has insufficient understanding of environmental fees and cannot pay them in a timely manner. Second, the construction party lacks an internal control mechanism. From the first floor to the front line of the project operation, the management process among various business departments is seriously disconnected, and the cost investment cannot be guaranteed to be consistent with the site. It is very important to establish a new system to restrict the use of environmental protection costs by the construction party. Third, the traditional site environmental monitoring is mainly reflected in paper forms. The efficiency of information transmission is low, and even data falsification exists, the data traceability is poor, and it is difficult for law enforcement agencies to obtain evidence.

The existing technology refers to the application of Internet of Things technology to environmental monitoring, but the traditional Internet of Things processes streaming data, once the data is attacked, it will be stolen, and the Internet of Things terminal equipment is suspected of being fake, and the data acquisition equipment may be tampered with, resulting in Data lacks authenticity
