Technical Field

[0001] The utility model belongs to the technical field of power facilities, and particularly relates to an electricity consumption acquisition terminal with an environmental monitoring function. Background Art

[0002] At present, the electricity consumption acquisition terminal mainly completes functions such as electricity consumption data of electric energy meters, including electricity quantity and electricity charge, settlement information, electricity consumption parameters, instantaneous electricity consumption, electricity consumption events, fault records, and remote communication. The current terminal does not have the monitoring functions for various electricity consumption environment information such as abnormal power supply of the terminal itself, lightning surge, temperature and humidity, air quality, solar radiation, salt fog concentration, magnetic field strength, geographic information, altitude data, and harmonic electric energy. Once a meter fault occurs, it is very difficult to distinguish whether it is caused by the hardware reason of the meter or the environmental factors at the electricity consumption site. If there is an abnormality in the user's electric energy meter, such as meter damage, or abnormal flying or stopping of electricity quantity, or burning of the electric energy meter, etc., it often causes electricity charge disputes.

[0004] An electricity consumption acquisition terminal with an environmental monitoring function includes:

[0005] A main board CPU, an environmental monitoring module connected to the main board CPU, an HPLC carrier communication module, a 485 communication module, a 4G communication module, a storage module, an indicator light, a liquid crystal display module, a metering chip, and an AD / CD power module for supplying power to the above components.

[0006] The environmental monitoring module and the main board CPU communicate with each other through high-speed UART; and communicate with an external monitoring device through micro-power wireless communication, and the environmental monitoring module adopts a hot-plug structure and has an ESAM security authentication module inside.

[0008] The power anomaly monitoring function module: When the power consumption acquisition terminal detects a power outage of the mains power, it may be caused by an abnormal power supply of the terminal itself, and there may be a situation where the mains power is on but the terminal has no power. The power monitoring function monitors whether the power supply is normal;

[0009] The lightning surge monitoring function module is used to monitor the short-term overvoltage conditions generated by the switching of internal electrical equipment in the system and external lightning strikes;

[0033] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

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

[0035] As Figure 1 shown, an electricity collection terminal with environmental monitoring function includes:

[0036] Main board CPU, an environmental monitoring module connected to the main board CPU, an HPLC carrier communication module, a 485 communication module, a 4G communication module, a storage module, an indicator light, a liquid crystal display module, a metering chip, and an AD / CD power module for powering the above components.

[0037] A high-speed UART communication is adopted between the environmental monitoring module and the main board CPU; a micro-power wireless communication is adopted between the environmental monitoring module and an external monitoring device, and the environmental monitoring module adopts a hot-swap structure and has an ESAM security authentication module inside. An encryption and decryption communication is adopted between the ESAM security authentication module and the external monitoring device.

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

[0039] As Figure 2 shown, the power anomaly monitoring function is completed by an external power monitoring device and is monitored through a power monitoring circuit (as Figure 3 shown). If there is power supply from the mains, the circuit can normally detect the high and low level switching; if the mains is abnormal, there will be a situation where there is power supply from the mains but the internal CPU cannot detect the high and low level switching. By monitoring the mains power supply, a basis for switching the auxiliary power supply of the electricity collection terminal is provided. If there is no auxiliary power supply, the power anomaly can be reported actively as soon as possible. This can prevent situations such as the disconnection of electricity collection due to power anomalies and abnormal electricity collection information.

[0040] The lightning strike monitoring function is completed by a lightning strike surge monitoring device, which mainly monitors the short-term overvoltage situations generated by the switches of internal electrical equipment in the system and external lightning strikes. In the power consumption system, 80% of the surges come from the power consumption equipment itself, and 20% come from lightning strikes. If high-voltage lightning strike situations occur frequently, the current varistors will fail under repeated impacts, which may damage the equipment. If a lightning strike surge monitoring module is adopted, by monitoring the lightning strike energy, it can provide overvoltage data for subsequent equipment to avoid lightning strike surges, formulate lightning strike surge standards, and situations such as explosion of meters. As Figure 4 shown, the lightning strike surge monitoring module collects lightning strike surge current and voltage signals through a lightning strike surge monitoring chip. If the lightning strike surge exceeds the set voltage threshold, the CPU reads the most recent 10 lightning strike surge events in the lightning strike surge chip through an electrically isolated serial port to determine the lightning strike surge energy. Since the lightning strike surge energy is relatively large, 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. As Figure 5 shown, it uses digital temperature and humidity sensors for monitoring, and the main chip communicates with the digital sensors through a serial port 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. To prevent the power consumption acquisition terminal from being exposed to extremely high or low temperatures and relatively high humidity environments, which may affect the service life of the equipment. The communication between the module and the CPU is through a serial port or I2C, and the power supply of the module 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 with an external environmental monitoring module to monitor the operating conditions of the equipment when it is exposed to dust and haze.

[0043] The ultraviolet monitoring function is completed by an extended ultraviolet monitoring device, which mainly monitors the sunlight radiation situation, counts the radiation intensity, and monitors the impact of ultraviolet rays on liquid crystals, casings, and exposed devices.

[0044] The rainwater monitoring function is completed by an extended rainwater monitoring device, which mainly monitors whether the terminal is used in rainwater to prevent abnormal use of the equipment.

[0045] The salt mist concentration monitoring function is completed by a dedicated salt mist concentration detection device. This module can be implemented in cooperation with an external monitoring device. For the salt mist concentration, there are no specific detection standards on the power consumption acquisition terminal and the electric energy meter, and a large amount of data needs to be monitored for verification. To prevent the situation where the salt mist concentration is too high and corrodes the circuit board.

[0046] The magnetic field intensity monitoring function is completed by a dedicated magnetic field detection device. The magnetic field monitoring is divided into constant magnetic field and power frequency magnetic field. This monitoring module mainly monitors the constant magnetic field to prevent strong magnetic interference to the master meter and the acquisition terminal, resulting in abnormal power consumption, abnormal meter reading data, etc.

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

[0048] The power consumption harmonic monitoring function is completed by a dedicated harmonic monitoring instrument, which monitors the harmonic conditions generated by power consumption equipment and realizes the harmonic metering function by using a metering chip with high-order harmonic sampling.

[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 can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
