Referring to FIG. 3, the security host 110 can set different preset parameters according to different locations installed by the sensing device 120 having the power saving function. The security host 110 sets preset parameters by bidirectional communication with the wireless module 122. The preset parameters may be preset vector values, preset change frequencies, and time thresholds.

The sensing device 120 having the power saving function receives the preset parameters to the control module 124 by using the wireless module 124 (S11). After the control module 124 receives the preset parameters set by the security host 110, the control module 124 of each power-saving function sensing device 120 uses the preset parameters as the startup or deactivation of the wireless module 122. in accordance with.

In use, if the sensor 121 detects the intrusion state, the instant-on wireless module 122 and the security host 110 communicate bidirectionally (S15). Otherwise, the detection module 123 senses the detection parameter (S12). Moreover, the wireless module 122 communicates with the security host in two-way communication only when the detection parameter reaches the preset parameter (S15).

The control module 124 analyzes the preset parameters and the detection parameters, and the control module 124 records the detection parameters to the memory 126, and the control module 124 determines whether the detection parameters reach the preset parameters, and timely The wireless module 122 is activated or deactivated, and the detection parameters are transmitted to the security host 110 by the wireless module 122.

The wireless two-way communication between the security host 110 and the sensing device 120 having the power saving function is established through wireless communication. The data of the wireless two-way communication is provided with the location of the power-sense sensing device 120 and the detection parameters. Here, the security host 110 receives the signal transmitted from the wireless module 122, and records a message or issues a warning message to the security personnel.

When the preset parameters are updated, the control module 124 receives the preset parameters set by the security host 110 by the wireless module 122 and covers the values of the preset parameters originally set by the control module 124. When the wireless module 122 receives the information, the control module 124 performs the two-way communication between the wireless module 122 and the security host 110 at a preset time interval, and the wireless module is disabled after the signal, the signal disappears, or the signal is not received. 122 communication.

Referring to FIG. 4, the detection module 123 is a gravity sensor 1231 (S12a). At this time, the detection parameter is the gravity vector value sensed by the gravity sensor 1231, and the preset parameter of the control module 124 is a preset vector value. In addition, the detection parameter is a vector change frequency sensed by the gravity sensor 1231, and the preset parameter of the control module 124 is a preset change frequency.

The control module 124 analyzes the data of the detection parameter and the preset parameter, such as the vector size, Differences in direction, etc. When the gravity vector value measured by the gravity sensor reaches the preset vector value (S131), or when the vector change frequency measured by the gravity sensor meets the setting of the preset change frequency (S132), the sensor 121 is represented. It is shaken by a specific external force. Therefore, the control module 124 initiates bidirectional communication between the wireless module 122 and the security host 110 (S15).

For example, when the power-saving function sensing device 120 is installed in a place with a large wind, such as a top floor of a building, a seaside, etc. At this time, the sensing device 120 having the power saving function vibrates frequently and rapidly due to the wind. Based on this, the preset change frequency can be set to a lower frequency. That is, the control module 124 activates the wireless module 122 only when the gravity sensor 1231 vibrates at a lower frequency, that is, when the vector change frequency is lower than the set preset change frequency (S15).

On the other hand, if the sensing device 120 having the power saving function is installed at a place where the external force is not easily shaken, the wireless module 122 can be activated when the vector change frequency reaches the preset change frequency (S15).

Referring to FIG. 5, the detection module 123 is a timer 1232 (S12b). Here, the preset parameter of the control module 124 is a time threshold. When the timer 1232 counts to the time threshold, the control module 124 sends a signal to initiate the two-way communication between the wireless module 122 and the security host 110.

Based on this, the security host 110 periodically receives the sensing state of the sensing device 120 having the power saving function. Therefore, when the security host 110 records the time of receiving the wireless signal, the time exceeds When the time threshold is exceeded, or the time difference between receiving the wireless signal is large, the security host 110 sends a warning message to inform the security personnel to check or check the problem to ensure the security of the client.

Here, the preset parameter of the control module 124 is a preset power value. The preset power value represents a value of the power consumption of the power module 125 to a certain extent. At this time, the control module 124 receives the power detection value detected by the power detector 1233, and compares whether the power detection value is lower than the preset power value. If the power detection value is lower than the preset power supply value, the control module 124 sends a signal to start the two-way communication between the wireless module 122 and the security host 110 (S15).

In this case, the security host 110 receives the wireless signal from the power-supplied sensing device 120 with the low power of the power module 125, and sends a warning message to inform the security personnel that the power module 125 should be replaced. Moreover, the security host 110 adjusts the preset power value and delivers the updated preset power value by two-way communication. Here, the sensing device 120 with the power saving function receives the preset parameters to the control module 124 by using the wireless module 124 (S11), and updates the preset parameters.

That is to say, the preset parameter is received by the wireless module 122 as a preset power value, and the preset power value in the control module 124 is updated. Moreover, the updated preset power value is lower than the original preset power value, so that the detecting module 123 can start the wireless module 122 when the power of the power module 125 is lower, thereby saving power.
