Problems solved by technology
However, since the portable wireless monitoring system uses a wireless connection, it is faced with the contradiction that the test terminal stops working (or enters a dormant state) causing the connection to be interrupted and the central processor is used to intelligently control the wireless test terminal.
If the control of the central processing unit is not used, the wireless monitoring terminal will work periodically and intermittently, and it will face the contradiction that the danger cannot be detected in time due to the interruption of the work when the monitored object is abnormal.

Embodiment Construction
[0014] Such as figure 1 As shown, the wireless monitoring system includes a central processing unit and a wireless monitoring terminal. The wireless monitoring terminal mainly includes a data acquisition module, a data transmission module and a control module, and the wireless monitoring terminal performs data transmission with the central processing unit through a wireless connection.
[0015] Such as image 3 and Figure 4 As shown, the specific workflow of the low power consumption realization of the wireless monitoring system is: initialization work, first collect and process data at T1 time, and the central processing unit judges whether the information is correct or not according to the calculation results. If the information of the monitored object is normal, the wireless monitoring terminal enters the dormant state for T2 time, and the central processor also enters the dormant state for about T2 time. After re-entering the working state, the central processor activel...

The invention discloses a method for realizing low power consumption of a portable wireless monitoring terminal. A reset function of a data acquisition module is skillfully used, namely a central processing unit (CPU) sends a reset command according to a monitoring result, transmits the reset command to the acquisition module through wireless connection, appropriately transforms change of a period sample signal of the data acquisition module during reset, and drives a resettable timer to control a circuit. By the command reset method, synchronization or stoppage of state switching (switching between a working state and a dormant state) at two ends of the wireless connection can be realized through appropriate cooperation with the calculation and processing of the CPU. In addition, the CPU can also change working strength of the wireless monitoring terminal in a command transmitting mode. By the scheme, reduction of power consumption of a system, particularly the portable wireless monitoring terminal is intelligently realized on the premise of not influencing monitoring effectiveness, the working time is prolonged, and the portability and the operability are improved.
Description
technical field [0001] The invention relates to the field of wireless monitoring (measurement) systems, and in particular to a method for realizing low power consumption of a portable wireless testing terminal. The method effectively realizes the intelligentization of the wireless monitoring system and reduces the power consumption of the portable wireless monitoring terminal. Background technique [0002] With the development of electronic communication technology, portable wireless monitoring (testing) systems are widely used in geological disaster monitoring, medical equipment, astronomy and meteorology, daily life and other fields. Since the portable terminal of the portable wireless monitoring system generally uses a replaceable battery or a rechargeable battery, it has high requirements for power consumption. As for the central processing equipment, there is generally a stable power supply, and the requirements for power consumption can be appropriately relaxed. At pr...
