Solar power supply water service gateway

Abstract

The invention discloses a solar power supply water service gateway. The first input end of a power supply is connected with the positive electrode phase of a battery and the negative electrode of the battery, the output voltage of the battery is compared with a low-voltage protection voltage, and a system enters a dormant state when the output voltage of the battery is lower than the low-voltage protection voltage. The second input end of the power supply is connected with the positive electrode of a PV and the negative electrode of the PV, the voltage of the solar cell is detected, if the voltage of the solar cell reaches the voltage for charging the storage battery, the system starts the charging circuit to charge the storage battery, and the charging system adopts an advanced MPPT algorithm to improve the charging efficiency. When the voltage of the solar cell is lower than the charging voltage, the charging circuit is disconnected. And the solar power supply water gateway is connected with various meters through an RS485 bus, and is used for collecting metering data and storing the metering data in a local storage device at the same time. Collected data are uploaded in a wireless mode at regular time, and interaction and data communication with an upper computer are carried out. The solar power supply water gateway can be applied to data acquisition circuits of flow meters, water meters and electric energy meters or circuits for data acquisition of the Internet of Things and energy conservation and energy consumption monitoring of building or industrial equipment, adopts solar power supply, does not depend on the mains supply, and is wider in application range, especially in a field environment without a power supply. And meanwhile, the system is compact in result, simple to install and debug, and reduces construction and maintenance costs.

Description

technical field [0001] The invention relates to a solar-powered water affairs gateway, which can be widely used in water supply data collection, data collection in water affairs-related systems, public building energy consumption collection systems, and is not limited by on-site power supplies according to installation arrangements, and is stable and reliable. Background technique [0002] At present, with the development of Internet of Things technology and the advancement of big data analysis technology, the collection of various basic data of water affairs has become more and more important. The real-time collection of physical quantities in the actual production process, and its application to on-site operation and maintenance management are also receiving more and more attention. Therefore, various sensors that collect physical quantities are used in practical projects. The data obtained by the sensors requires a collection device to collect and process the data, and at...

AI Technical Summary

Problems solved by technology

In some special application scenarios, the installation and maintenance of the collector becomes difficult, especially in some unattended equipment in remote mountainous areas without power supply. Equipment wiring power supply requires a large amount of construction and high costs, and there are still many uncontrollable factors

Battery power supply is a good choice to solve the above problems, but due to the limited power of the battery, it is not suitable for devices with high power consumption. In order to reduce power consumption, the device can only be in a low power consumption state or a sleep state most of the time. This leads to the fact that the device cannot work in real time
