Design Of Household Heat Measurement System Based On ZigBee

Nowadays,our country confronts with the urgent task of tansforming the mode of economic development.In our country,building circular economy and saving society is the development strategy all the time.In the northern city of our country,it usually supply heating in winter,but the management is still behind,most cities use the traditional system,which based on time to charge.It’s always result in a waste of resources and cannot satisfy the independent requirements of users,the method of charging is also unreasonable.So our country introduce the “one household one heat meter”charging mode.According to their needs the user can choose how much heat to use,which meet customers’ individual requirements,at the same time,the reasonable charging mode can save the country’s resource and improve residents’ consciousness of conservation.Therefore,our country begin to promote the household measurement to assess winter heating and make the mode as the important direction to reform.The manner of household measurement consist of manual method and wireless method,the latter is smart and efficient.But the current wireless measurement still need improve the reliability,efficiency and convenience.Household heating measurement based on ZigBee technology to collect heating data and upload to monitoring center via GPRS wireless network.The management is efficient and improve the existing charging mode.In order to guarantee the stability of information transmission,ZigBee modules use the CC2591 amplifier module to guarantee the user data are uploaded to concentrator accurately and reliably.Meanwhile,reaseach group design the energy harvesting circuits based on TI company’s bq25504 energy harvesting chip to collect solar energy,light energy for the Zig Bee routing module,which guarantee long-term normal work of the system,thereby solving the issue of short battery lifetime cycle and frequent replacement of battery.
