Description

technical field [0001] The invention belongs to the field of industrial Internet, and in particular relates to a thermal pipeline state parameter acquisition device based on semiconductor temperature difference power generation. Background technique [0002] The pressure and temperature changes in the thermal pipeline reflect the quality of the heat supply and the health of the heating system. Therefore, it is necessary to collect the parameters in the thermal pipeline during use, so as to achieve the purpose of monitoring and optimal regulation, and to achieve Lay the foundation for the simulation of the heating system. In addition, for central heating, there are still problems such as poor regulation, large energy waste, and difficulty in heating charges. In order to solve the above problems, a device that can monitor heating parameters online is added in the prior art. The module sends the information to the heating company, and then adjusts the heating parameters to red...

Problems solved by technology

[0003] However, both the monitoring of heating parameters and the transmission of information require power supply. In the prior art, the batteries are either replaced regularly, which requires regular checking of the power of the batteries; another is an external power supply, which is directly installed in the user's home. Although this can be Solve the problem of electricity consumption, but users are often unwilling to bear the additional electricity bills so that this scheme cannot be implemented; in addition, the collection and monitoring of the parameters in the outdoor heating pipeline cannot be connected to an external power supply, for example: at the entrance of the building or at the entrance of the unit, Or in the field, basement, shaft, etc.; for monitoring devices that cannot be connected to an external power supply, there is another kind of fluid kinetic energy power generation device that relies on liquid or gas flowing in the pipeline to generate electricity, but the overall structure of this device is complicated. It will increase the cost for later maintenance, and when there are too many measuring points, it will increase the resistance of pipeline transportation, which will have a negative impact on the operation of the heating system
