And 4, the base station sends the determined transmitting power to the sensor equipment.
And 5, the sensor equipment adjusts the transmitting power according to the received transmitting power.
According to the application example, when the sensor equipment is accessed to the network, the equipment information of the sensor equipment is obtained, the transmitting power is adjusted according to the obtained equipment information, and the service life of the sensor equipment is prolonged under the condition that the data transmission quality is ensured.
In the application example, the sensor equipment can be set to operate at the maximum transmitting power when being accessed to the network, and the base station allows the sensor equipment to be accessed to the network according to the network access request of the sensor equipment; for the sensor devices accessing the network, the base station may send a reporting instruction of the device information to all the sensor devices to obtain device information such as the position, the remaining power, the signal strength, and the like of each sensor device. The sensor equipment transmits the request to access the network with the maximum power, so that the influence on the access of the sensor equipment to the network and the uploading of the equipment information due to insufficient transmission power can be prevented.
And the base station determines the transmitting power of each sensor device according to the device information of each sensor device and sends the determined transmitting power to the device A, the device B, the device C and the device D. And when the sensor equipment receives the information of the transmitting power, the transmitting power is adjusted. If the residual electric quantity of the sensor equipment is the same, the equipment A is close to the base station, the distance between the equipment B and the equipment C is the same as that between the equipment C and the base station, and the distance between the equipment D and the base station is far; the determined transmission power of the device D is the largest, the transmission power of the device a is the smallest, and the transmission powers of the device B and the device C are the same.
Comparing the transmission power setting by adopting the related technology and the method of the application example; if the transmission power of the device a, the device B, the device C and the device D determined by the application example is X1, X2, X3 and X4 respectively; if a fixed transmission power is set according to the related art, and it is assumed that the transmission power X4 of all devices D is used as the transmission power of all sensor devices to ensure the data transmission quality, the transmission power of the device a is the largest difference from the transmission power determined by the method of the present application example, the difference between the transmission power set by the related art and the transmission power set by the present application example is X4-X1, the transmission power of the device B is the same as the transmission power determined by the method of the present application example, the difference between the transmission power set by the related art and the transmission power set by the present application example is X4-X2 and X4-X3, and the transmission power of the device a, the device B, and the device C is set to be too large compared with the transmission power determined by the present application example, and the difference is 3X4- (X1+ X2+ X3) compared with the present application example, therefore, the power consumption of the sensor device in the network is larger than that of the present application example. If the transmission power of the device a, the device B, the device C, and the device D is uniformly adjusted to be smaller than X4 but larger than X3, the transmission power of the device D is small, and a situation that the data transmission is slow due to signal instability, or even the transmission fails may occur. If the transmission power of the device a, the device B, the device C, and the device D is uniformly adjusted to be smaller than X3 but larger than X1, the transmission power of the device B, the device C, and the device D may be smaller, and therefore, the problem that the data transmission is slow or even the transmission fails due to unstable signals occurs. By the method for setting the transmitting power according to the device information, the normal working time of the sensor device can be prolonged while the data transmission quality is ensured.
In an exemplary example, when the sensor device of the present application example is connected to a base station and transmits device information to the base station, the base station may store the received device information in a preset storage area, and calculate the transmission power of each sensor device according to the received device information; sending the calculated transmission power to the sensor device; the sensor equipment adjusts the transmitting power according to the received transmitting power; in an exemplary embodiment, the base station stores the device information and the corresponding transmit power.

if a new sensor device is accessed into the network, after the new sensor device reports device information to the base station, when device interval information containing the device information is stored in the power mapping information, the transmitting power corresponding to the device interval information is used as the transmitting power of the sensor device;
in one illustrative example, the present application example method further comprises: when different distances between the sensor equipment and the base station are determined according to a preset strategy: the signal strength reference range of the transmitting power is not required to be adjusted; the method comprises the steps that new sensor equipment is accessed into a network, and before the transmitting power of the sensor equipment is calculated, the distance between the sensor equipment and a base station is determined according to the position of the sensor equipment in equipment information; the signal strength of the sensor device in the device information is located corresponding to the determined distance: and when the signal strength reference range of the transmitting power does not need to be adjusted, taking the current transmitting power of the sensor equipment as the transmitting power of the sensor equipment.
The application example aims at the situation that the signal strength (including but not limited to RSSI) of the sensor device can be interfered by other factors, and the transmission power is determined by judging the signal strength and the distance between the sensor device and the base station, so that the determination and the adjustment of the transmission power are more efficient and accurate.
In an exemplary embodiment, the base station of the application example acquires the device information according to a preset period;
in an exemplary embodiment, when the base station of the present application example determines that the position of the sensor device changes, the device information is acquired;
according to the acquired device information, the base station determines the transmission power of the sensor device.
If the position of the equipment received by the base station changes, the distance between the base station and the sensor is reduced and the signal intensity value is increased, the base station recalculates the transmitting power, transmits the transmitting power to the sensor equipment, adjusts the transmitting power in real time and reduces the transmitting power; if the position of the equipment received by the base station changes, the distance between the base station and the sensor is increased, and the signal intensity value is reduced, the base station recalculates the transmitting power, sends the transmitting power to the equipment, updates the transmitting power in real time, and increases the transmitting power; if the position of the equipment received by the base station is not changed and the signal strength value is not changed, the equipment keeps the original transmitting power.
The application example acquires the equipment information of the sensor equipment when the running state of the sensor equipment changes, and adjusts the transmitting power through the acquired equipment information, so that the service life of the sensor equipment is prolonged under the condition of ensuring the data transmission quality.
