Abstract

The invention relates to a hydrological telemeter. The hydrological telemeter solves the technical problems that after an external alternating current is powered down, normal working of an existing hydrological water resource terminal cannot be achieved, and the existing hydrological water resource terminal is large in size, high in energy consumption, low in measurement precision, poor in operational stability and low in reliability. The hydrological telemeter comprises a main control circuit board, and a touch display screen, a data storage unit, a temperature and humidity sensor, a switching power supply module, a water level indicator, a water manometer, a flowmeter, a rain gauge and a GPRS / GSM module which are connected with the main control circuit board, wherein a central processing unit is arranged on the main control circuit board, a solar photovoltaic panel, a PWM charging circuit and an accumulator which are connected in sequence are further arranged on the main control circuit board, and the PWM charging circuit is connected with the main control circuit board; a DC / DC switching circuit which is connected with the central processing unit is further arranged on the main control circuit board, the switching power supply module is connected with the DC / DC switching circuit, DC 12V voltage is output by the switching power supply module, the DC 12V voltage is used as the input of the DC / DC switching circuit, and DC 3.3V voltage is output by the DC / DC switching circuit. The hydrological telemeter is widely applied to remote collection and transmission of hydrological water source information.

Description
