If the user's electricity meter has an abnormality, such as the meter is damaged or the electricity is flying away, stopping abnormally, the meter is burned, etc., it often causes electricity bill disputes.

[0005] Mainboard CPU, environmental monitoring module connected to the mainboard CPU, HPLC carrier communication module, 485 communication module, 4G communication module, storage module, indicator light, liquid crystal display module and metering chip, and AD / CD power supply module for supplying power to the above components,

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the invention, so the present invention is not limited by the specific implementation disclosed below.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] like Figure 1 As shown, a power consumption collection terminal with environmental monitoring function includes:

[0036] Mainboard CPU, environmental monitoring module connected to the mainboard CPU, HPLC carrier communication module, 485 communication module, 4G communication module, storage module, indicator light, liquid crystal display module and metering chip, and AD / CD power supply module for supplying power to the above components,

[0037] The environmental monitoring module uses high-speed UART communication with the mainboard CPU; micro-power wireless communication is used between the external monitoring device, and the environmental monitoring module adopts a hot-swappable structure, with an ESAM security authentication module inside, and encryption and decryption communication is used between the ESAM security authentication module and the external monitoring device;

[0038] The environmental monitoring module of the electricity consumption collection terminal can expand the environmental monitoring functions such as power supply anomaly monitoring function, lightning strike monitoring function, temperature and humidity monitoring function, environmental quality monitoring function, ultraviolet monitoring function, rain monitoring function, salt spray concentration monitoring function, magnetic field strength monitoring function, geographic information function, and electricity consumption harmonic monitoring function.

[0039] like Figure 2 As shown, the power supply abnormality monitoring function is completed by an external power supply monitoring device, through the power supply monitoring circuit (such as Figure 3 If the mains is powered, the circuit can detect the high and low level switching normally; if the mains is abnormal, the mains is powered but the internal CPU cannot detect the high and low level switching. By monitoring the mains power supply, the auxiliary power supply of the power collection terminal is switched based on the basis. If there is no auxiliary power supply, the power supply abnormality can be actively reported as soon as possible. This prevents power collection disconnection and power collection information abnormality caused by power supply abnormality.

[0040] The lightning monitoring function is completed by the lightning surge monitoring device, which mainly monitors the short-term overvoltage conditions caused by the switches of the electrical equipment inside the system and the external lightning strikes. In the power system, 80% of the surges come from the electrical equipment itself, and 20% come from lightning strikes. If high-voltage lightning strikes occur frequently, the current varistors will fail under repeated impacts, thereby damaging the equipment. If a lightning surge monitoring module is used, by monitoring the lightning energy, it can provide over-voltage data for subsequent equipment to avoid lightning surges, formulate lightning surge standards, and blow up meters. Figure 4 As shown in the figure, the lightning surge monitoring module collects lightning surge current and voltage signals through the lightning surge monitoring chip. If the lightning surge exceeds the set voltage threshold, the CPU switches on and off the electrical isolation serial port to read the last 10 lightning surge events in the lightning surge chip, thereby determining whether it is lightning surge energy. Due to the large lightning surge energy, the power supply of this module needs to be configured separately.

[0041] The temperature and humidity monitoring function is completed by a dedicated temperature and humidity monitoring device, such as Figure 5 As shown, digital temperature and humidity sensors are used for monitoring, and the main chip and digital sensors communicate via serial ports to obtain real-time temperature and humidity data. Since this module is a low-voltage module, electrical isolation is required when communicating with the main chip. Avoid exposing the power collection terminal to extreme high and low temperatures and high humidity environments, which will affect the service life of the equipment. Serial or I2C communication is used between the module and the CPU, and the module power supply is a separate isolated power supply. The isolation withstand voltage between the temperature and humidity module and the CPU is 4000VAC.

[0042] The environmental quality monitoring function is completed by a dedicated environmental quality monitoring device. This module communicates data with the external environmental monitoring module to monitor the operation of the equipment exposed to dust and haze.

[0043] The ultraviolet monitoring function is completed by the extended ultraviolet monitoring device, which mainly monitors the sunlight radiation, counts the radiation intensity, and monitors the influence of ultraviolet rays on the liquid crystal, casing, and exposed devices.

[0044] The rain monitoring function is completed by the extended rain monitoring device, which mainly monitors whether the terminal is exposed to rain during use to prevent abnormal use of the equipment.

[0045] The salt spray concentration monitoring function is completed by a dedicated salt spray concentration detection device. This module can be implemented in conjunction with an external monitoring device. There is no specific detection standard for salt spray concentration on the electricity collection terminal and the energy meter. A large amount of data needs to be monitored for verification. This prevents the circuit board from being corroded by high salt spray concentration.

[0046] The magnetic field strength monitoring function is completed by a dedicated magnetic field detection device. Magnetic field monitoring is divided into constant magnetic field and industrial frequency magnetic field. This monitoring module mainly monitors the constant magnetic field to prevent strong magnetic interference to the total meter and collection terminal, which may cause abnormal power consumption and abnormal meter reading data.

[0047] The geographic information function is completed by a dedicated geographic information device, which mainly completes the collection of geographic information data, including the collection of longitude, latitude and altitude data.

[0048] The power harmonic monitoring function is completed by a dedicated harmonic monitoring instrument, which monitors the harmonics generated by electrical equipment and uses a metering chip with high-order harmonic sampling to achieve the harmonic metering function.

[0049] It should be noted that the embodiments mentioned above illustrate rather than limit the present invention, and those skilled in the art will be able to design alternative embodiments without departing from the scope of the claims. Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, so the scope of protection of the present invention shall be subject to the scope defined by the claims.
