[0002] At present, in the field of wireless remote meter reading, due to the constraints of the environment, most of the wireless remote meter reading devices are powered by disposable lithium batteries, and the service life of these devices is more than 3 years. Quite sensitive, usually the sleep standby current is uA level, so these devices only wake up to work in a specific period of time, and continue to sleep after processing. However, these devices often need to set and operate their parameters during use. If the device is always in the dormant state during operation, it will not be able to operate; if the device is always in the wake-up state, the power consumption of the hardware will increase greatly, the battery life will decrease sharply, and the long-term operation of the device cannot be realized; Device-specific wake-up time to set and operate, will greatly reduce device flexibility

[0022] Please refer to figure 1 As shown, a wireless remote meter reading device with an ultra-low power consumption wake-up function, it includes a control chip 1, and the control chip 1 is internally provided with an RTCC ( Real-time clock / calendar) module 11: The wireless remote meter reading device also includes a unit circuit 2 that is bidirectionally connected with the control chip 1 to perform the following functions: when the control chip 1 is activated by the RTCC (real-time clock / calendar) module 11 After waking up, the control chip 1 judges whether the wake-up interval time reaches the set time; if the time is not reached, the control chip 1 controls the wireless remote meter reading device to continue to sleep; if the time has been reached, the control chip 1 initializes the unit circuit 2 that can trigger the wake-up. It enters the detection mode; when the unit circuit 2 that can trigger wake-up detects a corresponding wake-up signal and transmits it to the contro...

The invention relates to a wireless remote-transmission meter reading device with an ultralow-power-consumption awakening function and an awakening method thereof. The device comprises a control chip, wherein an RTCC (real time computer complex) module which is bi-directionally connected with a CPU (central processing unit) processor and can awaken the control chip at intervals is arranged inside the control chip; the wireless remote-transmission meter reading device also comprises a unit circuit which is bi-directionally connected with the control chip and is capable of being triggered to awake. The wireless remote-transmission meter reading device is in a dormancy state at ordinary times and is only awaken to work after receiving an awakening signal of an external device, so that the power consumption of the device is greatly reduced, the service life of a battery is greatly prolonged, the parameters of the device also can be conveniently set and operated, and the flexibility in use can be improved.
