Embodiment 1

[0033] like Figures 1 to 2 As shown, the wireless power meter reading system with terminal query function in this embodiment includes a meter reading unit of a metering instrument, a meter reading management unit, and a network query unit;

[0034] The meter reading unit of the metering instrument includes an electric meter data collector and an electric meter data concentrator, the electric meter data collector is installed on the user's electric meter, and the electric meter data concentrator can collect electric meter data from multiple electric power data collectors. The meter data collector includes a power supply module, a single-chip microcomputer and a first radio frequency transmission module. The output end of the power supply module is respectively connected to the power supply input end of the single-chip microcomputer and the first radio frequency transmission module, and is used to supply power to the single-chip microcomputer and the first radio frequency transm...

Embodiment 2

[0043] like image 3 As shown, on the basis of the above-mentioned Embodiment 1, the wireless power meter reading system with terminal query function in this embodiment further includes the arrears early warning unit, and the arrears early warning unit uses the payment information and consumption of the electricity meter data collector. When the remaining value is lower than the set value, the arrears warning unit sends out an instruction to issue an early warning to the user to remind him to pay in time.

[0044] In this embodiment, the arrears warning unit includes a dialing unit.

[0045] Further, the dialing unit is a multimedia message center, a short message center or a multimedia service center.

[0046] Further, the dialing unit sends information to the mobile phone number bound to the meter reading unit of the metering instrument through a short message cat, or sends WeChat to the microsignal bound to the meter reading unit of the metering instrument through the WeCh...

Abstract

The invention discloses a wireless power meter reading system having the terminal querying function, which comprises a metering instrument reading unit, a meter reading management unit and a network querying unit. Codes stored in a concentrator in corresponding connection with a power meter data collector, and the address code of the concentrator, are converted into two-dimensional code labels and dynamically displayed. Each two-dimensional code label is endowed with a unique physical address. A single-chip microcomputer transmits the two-dimensional code labels to a power meter data concentrator in the form of radio signals through a first radio frequency transmission module. The power meter data concentrator processes the two-dimensional code labels and then outputs processed two-dimensional code labels to the meter reading management unit through a GPRS module. The meter reading management unit is connected with the network querying unit and is used for verifying the identity of a use. When the user passes the identity authentication, the network querying unit outputs the corresponding query information.

Description

technical field [0001] The invention relates to a wireless power meter reading system with terminal inquiry function. Background technique [0002] At present, my country is vigorously building a strong smart grid, of which smart meter collection is an important part of the strong smart grid. The existing smart meter reading methods are mainly wired and wireless. The wired method requires rewiring, which is costly and is not suitable for some occasions, especially in rural areas. The wireless method is mainly based on GPRS or wireless sensor network technology. It is necessary to modify the user's electricity meter, add the corresponding GPRS module, etc., to realize the separate collection of the data of each user's electricity meter, which is costly and difficult to popularize. [0003] Many current meter reading systems are equipped with the function of automatically stopping the supply of arrears. Once the amount in the user's account is zero, the supply will be stopped...
