Abstract
The utility model discloses a telemetering terminal with a re-switching-on function, which comprises a shell and an internal circuit structure, wherein the circuit structure comprises a central processing unit, a power supply circuit, a battery charging and discharging control circuit, a liquid crystal display, a data memory module, an output control interface, a wireless communication module and a power switch. The telemetering terminal is characterized in that the power switch is a circuit breaker, a current/voltage sensor is additionally arranged and used for acquiring system load information, and after the system load information is processed by the central processing unit, a control signal is outpu to the circuit breaker. According to the telemetering terminal, when a circuit fault occurs, the circuit breaker can automatically trip so as to protect a device; and after the sensor detects that the system fault is recovered, a control signal is output for starting the circuit breaker to carry out a re-switching-on operation, so that the device automatically starts and runs normally, therefore. The telemetering terminal has the characteristics of large discharge current capacity, reliable switching on and off, energy conservation, environmental friendliness, and the like and is capable of saving labor cost.
