Mass Concrete Solutions

 箭头  Background

     Mass concrete, English is concrete in mass. my country's "Construction Standard for Mass Concrete" GB50496-2018 stipulates that the minimum geometric size of concrete structures is not less than 1m. Concrete that causes harmful cracks due to temperature changes and shrinkage is called mass concrete.

    During mass concrete pouring, temperature monitoring is very important. When the temperature change exceeds the national standard, appropriate measures should be taken to cool down.

 箭头  Functional Requirements

  • · Monitor the real-time temperature of concrete.
  • · Battery powered, low power consumption.
  • · Wireless long-distance transmission of data, and wireless star networking with the same block of concrete.
  • · Temperature measurement products should be waterproof and anti-high temperature treatment.

 箭头  Feature Design

      Hengyi Technology has accumulated rich experience in the field of wireless transmission and sensors.

         Wireless transmission

                Mass concrete is composed of cement and steel bars. The initial water content and temperature of pouring are relatively high. Each mass concrete needs multiple measuring points. Each measuring point is divided into three parts: upper, middle, and lower. There is a certain distance between the points. The measuring point uses LORA for wireless data transmission, and uploads the concrete temperature data to the LORA gateway through LORA, and the LORA gateway uploads the data to the cloud server.

                LORA is a low-power, long-range, high-penetration wireless technology. It is very suitable for use in the scene of concrete temperature measurement.

         Sensor

                Hengyi Technology has obtained many patents on the development and application of TOF, temperature and humidity, and gas sensors. In the field of concrete temperature measurement, Hengyi Technology combined advanced sensor technology at home and abroad, and developed a high-precision digital temperature sensor module. This temperature measurement module can work in a high temperature soaking environment.

          Cloud Platform

                According to the characteristics of the concrete temperature measurement industry, Hengyi Technology has made a detailed design on its own cloud platform to make it more suitable for concrete temperature measurement according to national standards. Powerful and easy to use.
