Remote control metering system

Abstract

The invention discloses a remote control metering system, comprising a wireless intelligent gauging meter and a handheld intelligent terminal; the wireless intelligent gauging meter comprises a base meter, a processor module, a data acquiring module, a storage module, a valve control module, a power supply module, a wireless arousing module and a wireless communication module; the wireless arousing module is connected with a processor by a serial port; the wireless communication module is connected with the processor module by a serial port; the handheld intelligent terminal comprises a terminal processor module, a wire communication module, a display module, a keyboard module, a power supply module, a wireless communication module and an IC (integrated circuit) card reading-writing module; the wireless communication module is connected with the terminal processor module by a serial port; and the IC card reading-writing module is connected with the terminal processor module by a data port. The wireless communication module of the wireless intelligent gauging meter only needs to be activated in need of communication, thus effectively reducing the electric energy consumption of such gauging meters and prolonging the battery work time of the gauging meter.

Description

technical field [0001] The invention relates to a metering system, in particular to a remote control metering system. Background technique [0002] A wireless meter usually includes six modules including a base meter, a valve control module, a processor module, a communication module, a data acquisition module and a power supply module. The communication module is used for data communication between the wireless meter and the outside world, and is the most energy-consuming component in the wireless meter. In order to reduce energy waste, the existing technology usually adopts a sleep / wake mechanism, that is, when the wireless meter does not need to communicate with the outside world, it will turn off the wireless communication module and let the microprocessor enter the sleep state, and the timer will Wake up the microprocessor and the wireless communication module to receive external data. Periodic timing sleep / wake mechanism greatly prolongs the working time of the batte...

Problems solved by technology

However, since the wireless meter does not know when the outside world will transmit data to itself, usually, the wireless meter can only wake up in a certain period of time to query or synchronize the needs of the outside world. This mechanism does not Solve the problem of energy waste caused by waking up the microprocessor and wireless communication module when there is no communication demand from the outside world. In addition, this mechanism also brings delay problems, that is, when the outside world needs to transmit data to the wireless meter, it may Since the wireless meter is in a sleeping state, it cannot respond to external requests in real time
