Intelligent object network heat meter and management system thereof

Abstract

The invention discloses an intelligent object network heat meter and a management system thereof, which belong to heat meters. The heat meter is mounted near a medium pipeline of a heat exchanger and comprises a CPU (central processing unit) controller and a flow metering device. The CPU controller is connected to a flow valve and the flow metering device on the medium pipeline of the heat exchanger, and the CPU controller outputs control signals to control on and off of a flow valve, reads metering data from the flow metering device and deducts initial values stored in an EPPROM (electrically erasable programmable read-only memory) according to metering data information. The intelligent object network heat meter and the management system thereof are simple in structure, functionally realized based on the technique of internet of things, suitable for being mounted and used in various areas, and wide in application range.

Description

technical field [0001] The invention relates to a heat energy meter, in particular to an Internet of Things intelligent heat energy meter and a management system thereof. Background technique [0002] At present, domestic energy prices are in line with international standards, resulting in frequent price fluctuations. Therefore, new requirements are put forward for metering heat meters. The purpose is to achieve functions such as measurement, control, charging and management. None of them have the aforementioned functions. Taking thermal energy supply as an example, the thermal energy meters currently produced in China can be roughly divided into two types in terms of payment methods: one is to pay first and then use them, such as IC card thermal energy meters, which have pre-stored thermal energy and stop when the fee is exhausted. Supply, the user must hold the IC card to the designated place to purchase and complete the corresponding input function before the heat supply ...

Problems solved by technology

[0002] At present, domestic energy prices are in line with international standards, resulting in frequent price fluctuations. Therefore, new requirements are put forward for metering heat meters. The purpose is to achieve functions such as measurement, control, charging and management. None of them have the aforementioned functions. Taking thermal energy supply as an example, the thermal energy meters currently produced in China can be roughly divided into two types in terms of payment methods: one is to pay first and then use them, such as IC card thermal energy meters, which have pre-stored thermal energy and stop when the fee is exhausted. Supply, the user must hold the IC card to the designated place to purchase and complete the corresponding input function before the heat supply can be resumed. However, there are artificial unreliable factors in the data exchange between the IC card and the heat meter, and the price of heat energy cannot be adjusted in real time. Defects, such as price adjustments, etc.

The second is to pay after use, which is also the payment method widely adopted by most heat energy providers at present, that is, to measure through ordinary heat energy meters, to manually copy the information on the meter end and then to calculate the charge according to the heat energy price, and this method exists The shortcomings of data transcription and heat energy fee collection are difficult, and it is difficult for the supplier to control the use of heat energy by the user. In case of heat energy price adjustment, the price and consumption before and after the adjustment need to be counted and calculated separately, which invisibly increases the workload of the staff.

[0003] In addition, all kinds of remote meters, remote meter reading, and remote control meters have appeared in the market, but these heat meters are all point-to-point transmission modes, that is, the terminal heat meters transmit data to the reading station through wired or wireless transmission. The meter operator’s hand copy device or remote management system, but because it is point-to-point transmission and the wireless signal is easily interfered by external frequencies and buildings, the data copying rate is not ideal, so it is not yet possible to realize remote price adjustment and remote reading of terminal heat meters Meter data and other functions, and due to the attenuation of the signal, the application range of this type of heat meter is limited
