Problems solved by technology

[0004] 1. The meter reading work is labor-intensive and inefficient;
[0005] 2. Omissions and mistakes are inevitable;
[0006] 3. The cycle from meter reading to charging is long;
[0007] 4. High management costs;
[0008] 5. It is easy to be impersonated by criminals, and there are potential safety hazards
However, the cost of this camera direct-reading remote water meter is relatively large, and it is restricted by development conditions in practical applications.
[0014] (4) Fixed telephone communication remote water meter: Due to the frequent use of modern home telephones, the success rate of meter reading calls is low, and the communication efficiency cannot be guaranteed
At present, the existing meter reading systems and technical methods mainly include wired meter reading systems, handheld meter reading systems and wireless meter reading systems. Among them, the wired meter reading system increases the cost and difficulty of integrated wiring and reduces the application flexibility of the system. The wired meter reading system has been difficult to popularize and apply widely; the handheld meter reading system requires the meter reading department to use a handheld meter reading device to read the data, which is not easy to manage and only a small amount of data can be copied, and its automation is low and limited. Although the existing wireless meter reading system uses wireless transceiver equipment to transmit data, it does not need special wiring. The system structure is simple, which can save manpower and material resources. Compared with the wired meter reading system and the handheld meter reading system, it has more application advantages. However, its preparation cost is high and the range of meter reading is small. Therefore, it is necessary to design a new system to bring technical improvements to power supply companies and bring many conveniences to the electricity consumption of the majority of users. It has very good practical significance and economic benefits. It can improve meter reading efficiency, reduce manual errors, save operating costs, and realize automatic meter reading functions

Embodiment Construction

[0039] The invention provides an electric power remote meter reading system, which includes an electric meter arranged at the location of the electric power user for measuring the power consumption of the user; the electric meter includes an ordinary electric meter and an intelligent electric meter.

[0040] Ordinary meters are connected to building collectors through RS485 bus, and building collectors and smart meters communicate with concentrators through power line carrier. The concentrator realizes two-way data transmission with the meter reading central server through wireless communication; the wireless communication network is GSM network, GPRS network or CDMA network. Preferably, the meter reading central server is connected to multiple sets of concentrators through a wireless communication network, and each set of concentrators is connected to multiple building collectors and multiple smart meters. The preferred building collector includes an extended memory module bi...

Abstract

The invention discloses an electric remote meter reading system. The electric remote meter reading system comprises a common electricity meter and an intelligent electricity meter; a building collector and the intelligent electricity meter are connected with a concentrator; bidirectional data transmission of the concentrator with a meter reading central server is realized via wireless communication. The electric remote meter reading system possesses outstanding substantive distinguishing features and remarkable improvement compared with the prior art. More specifically, a conventional carrier wave centralized collecting system is taken as the base, coordinate application with electric energy meters is adopted, prepayment functions and black out and power on control of remote meter reading systems are realized under management control by a remote centralized meter reading master station, an electric charge collection problem existing for a long term is solved for electric power departments, and management level and service level are improved.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an electric remote meter reading system. Background technique [0002] Power meter reading is an important link in the modern power system. Traditional power meter reading is mostly done manually at the scene to read data, which not only consumes a lot of human resources, but also has problems with the timeliness and accuracy of data. with many shortcomings. [0003] As we all know, traditionally, most of the metering and charging and management of civil water meters, electricity meters, heat meters and gas meters are carried out by personnel going indoors to manually read the numbers: the meter reading personnel enter the house to read the user's water consumption data, and then Perform statistics and billing, and then charge at the user's home. This method has many disadvantages: [0004] 1. The meter reading work is labor-intensive and inefficient; [0005] 2. O...
