Description

Technical Field

[0001] The invention relates to the technical field of electric power marketing, in particular to a portable multifunctional meter reading instrument. Background Art

[0002] With the rapid development of smart grid technology, traditional energy meters have gradually exposed a series of problems in efficiency, accuracy, management and safety. Although the existing meter reading technology has improved the work efficiency of power companies and users to a certain extent, there are still many problems that need to be solved in traditional meter reading equipment. In particular, there is a core problem in meter reading when canceling accounts or replacing faulty meters, that is, the lack of power supply function. The LCD display of a single-phase energy meter turns off the display after 2 hours of power failure, and does not support wake-up. It is impossible to read the meter code and bottom data of the energy meter in the case of power outage. Although the LCD display of a three-phase energy meter can be awakened by pressing a button after a power outage, due to the long-term use and power outage of the three-phase energy meter, the power outage meter reading and the full pressure loss battery voltage are often insufficient. The LCD display cannot be awakened by pressing a button without connecting to an external power supply, and the meter code and bottom data of the energy meter cannot be read. When canceling accounts or replacing faulty meters, there may be a situation where the power supply cannot be normally connected to the site to power the energy meter, and normal meter reading cannot be performed. Every time, the staff needs to carry large power converters and cable reels to the site to get electricity. Irregular operations during the power-taking process may lead to certain safety risks and cause personal electric shock casualties. Especially in remote areas or complex installation environments, the time and energy costs required for manual meter reading are high. The staff needs to carry heavy equipment and visit multiple users to complete the reading of the energy meter, which not only affects the efficiency of meter reading, but also increases the investment of manpower and material resources. At the same time, during the manual meter reading process, especially in poor visibility or insufficient light, the staff is prone to reading errors. Although most meter readers have undergone certain training, due to the manual nature of the reading process, they are inevitably affected by factors such as vision and lack of concentration. Data errors caused by such human factors may lead to inaccurate electricity metering, thereby affecting the power company's billing, settlement, and energy analysis and other related work. Summary of the invention

[0003] In response to the above problems, it is necessary to develop a portable multifunctional meter reader that has a high level of automation and can meet the data collection and processing needs of various electricity meters, aiming to improve the automation level of data collection of power-off electricity meters, optimize the workflow, and improve work efficiency.

[0004] Therefore, the present application proposes a portable multifunctional meter reading instrument, comprising:

Even without a mobile phone or network connection, the device can operate independently and store data to ensure uninterrupted work.

[0008] Touch screen display interface for viewing, operating, editing and arranging data;

[0009] Bluetooth function module, used for wireless communication with mobile phones and other devices, uploading the collected power data to mobile phone applications, and generating electronic document records

[0010] The storage battery is connected to the voltage terminal of the electric energy meter through the power management module to provide stable voltage power supply for the electric energy meter.

[0011] The RS-485 communication interface is connected to the RS-485 terminal of the electric energy meter, and the communication interface stores the electric energy data collected from the electric energy meter in the built-in storage module through the data transmission channel.

[0013] The Bluetooth function module is connected to the touch screen display interface and the built-in storage module, and uploads the data viewed or edited on the touch screen display interface to the mobile phone application via Bluetooth wireless transmission.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Self-contained power supply: The portable multi-function meter reader carries AC220V, AC100V, AC57.7V power frequency batteries, which can provide reliable power supply for single-phase and three-phase energy meters. The portable multi-function meter reader is small in size and light in weight, easy to carry and move. This allows meter readers to read meters in different locations and environments, especially in areas that are difficult to reach or have limited space, greatly improving work efficiency.

[0016] 2. One-click reading: The portable multi-function meter reader reads the electric energy meter data through RS-485 communication, and stores and displays the data locally, which is convenient for the staff to record the data. At the same time, the data can also be transmitted to the mobile phone through the Bluetooth function. The meter reader can customize multiple reading schemes, realize one-click batch data reading function, and improve the efficiency of meter reading.

[0017] 3. Intelligent data diagnosis: Through built-in judgment rules, intelligent diagnosis is performed on whether the meter code data read is abnormal. If data abnormality is found, an alarm will be automatically given. The portable multi-functional meter reader can perform intelligent diagnosis on data abnormalities such as meter code jump, meter code reverse (indication drop), daily and monthly electricity consumption, meter code stop, reverse running, etc. It can timely detect abnormalities in the meter reading, avoid incorrect customer electricity bill settlement due to inaccurate measurement, and ensure the fairness of interests between power supply companies and electricity users.
