Judging whether the calculated difference value is smaller than a preset stage boundary value. If it is smaller, switching to the second stage. If the power is not smaller than the preset value, the transmitting power is calculated according to the power strategy of the current stage according to the feedback signal strength, and the attenuation value of the program-controlled attenuator is adjusted.

The setting manner of the transmission power in this embodiment is to construct a compression policy based on an exponential function to set the transmission power. Specifically, the function is constructed；D N = P N -P N-1 (N≧1，S∈[1，127] 。
In the above formula, P represents a set transmission power, S represents a received signal strength, D represents a power attenuation value, k represents a power reduction coefficient, N represents a sequence number, and P 0 I.e. the first transmit power, S 0 I.e. the first received signal strength, D 1 I.e. the first power attenuation value.
That is, each time the transmission power is converted from the previous transmission power and the signal reception strength, and the power attenuation value is further calculated based thereon. In actual process P 0 A larger initial value is used to ensure effective communication.
According to e -x As can be seen, in this embodiment, the transmit power is reduced at an exponential rate to quickly acquire the critical state. The critical state refers to that when the transmission power is reduced to a certain level, the detection device cannot receive the signal. The minimum stable received information transmitting power is a critical value, corresponding to the signal receiving sensitivity of the detecting device. The stable receiving index is stable for continuous M times of communication interaction. Aiming at the current equipment object, the conventional meter data reading is used as an index, the communication data length is about 100 bytes, and the M value can be designed according to the detection level requirement.
The acquisition threshold includes two phases, namely a first phase and a second phase.
In the first stage, the transmit power is rapidly reduced until P N A situation occurs in which a stable reception index cannot be reached. I.e. critical value is at P N-1 、P N Since the minimum setting precision of P is 1, when P N-1 And P N When the difference is small, i.e. P N-1 -P N <Epsilon is a preset stage boundary value, can be initially set to 10, and enters a second stage.
In the second stage, P N-1 Sequentially decreasing by 1 (i.e. the preset value is 1 as described above) until P M Can not achieve stable reception, and the critical value is P M-1 I.e. also equal to P M -1。
When P N-1 And P N When the difference is larger, the design efficiency is lower, and the compression strategy is continuously used. When P N When the stable receiving index cannot be reached, S cannot be obtained at this time N Will S N Set to-1, at which point P N+1 =P N *e k . With P N-1 >P N+1 >P N Thereby achieving further compression so as to satisfy the above-described conversion characteristic condition (P N-1 -P N <Epsilon) into the second stage.
