Technical Field

The present invention relates to a network bridge, and more particularly, to an automatic control method and a readable storage medium for wireless power of a network bridge.

Background

The camera monitoring is increasingly applied to daily life of people, and the transmission of monitoring data is also more and more frequently completed by matching with a network bridge in elevator monitoring. The bridge device is generally arranged on the top of the elevator car and at the top end of the elevator shaft to carry out point-to-point wireless transmission, and the transmission space is a closed space of the elevator shaft. The method is characterized in that the method is calculated according to a wireless signal strength calculation formula RSSI = wireless transmission power + antenna gain at a transmitting end + antenna gain at a receiving end-free space loss, the free space loss is determined according to the distance between equipment under the condition that the antenna gain of the equipment leaving a factory is fixed, and the wireless signal strength of the network bridge changes along with the change of the free space loss. As the box approaches the top of the hoistway, the signal strength between bridges becomes stronger and device bridging due to signal saturation may occur but normal communication is not possible. When the car is far away from the top end of the elevator, the signal strength between bridges is weakened continuously, bridge connection drop can occur due to low wireless transmitting power configuration, or the bridge connection speed is low, so that the monitoring is blocked and the screen is dark.

When signal saturation occurs between the bridges, the sending power of the bridges needs to be artificially modified to reduce, and when the signal strength is too weak, the sending power of the bridges needs to be artificially modified to increase, so as to ensure the normal transmission of bridge signals of the bridges.

Because the transmission power of the existing network bridge cannot be automatically regulated, the following defects exist:

1. manually adjusting the wireless transmission power of the equipment requires repeated manual page modification by maintenance personnel, which is time-consuming, labor-consuming and low in efficiency;

2. when the bridge moves to the farthest position along with the elevator bridge box, the bridge is possibly disconnected or the monitoring is blocked due to the reduction of the wireless transmission power.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature.

The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.

As shown in fig. 1, an automatic regulating method for wireless power of a network bridge mainly includes the following steps:

1. after bridging an AP (wireless access point) and an STA (terminal), starting a timer, and monitoring the change of signal intensity values of the AP and the STA;

2. setting a danger value and a safety value of signal intensity, wherein the danger value is-20 dBm, and the safety value is-40 dBm;

3. when the read signal strength value is smaller than the signal strength safety value, the bridging device transmits data at the maximum power;

4. when the three RSSI values of the signal strength are continuously monitored to be larger than a safety value (-40 dBm) and smaller than a dangerous value (-20 dBm), the wireless transmission power of the bridging equipment starts to be adjusted, and when the read RSSI value exceeds the safety value by 3dBm, the wireless transmission power of the bridging equipment is correspondingly reduced by 2 dBm. For example: the maximum power of the bridge device is 25dBm, the background reads RSSI of-30 dBm, and the actual transmit power = 25- (40-30)/3 × 2=19 dBm.

5. When the continuously monitored signal strength is greater than the dangerous value, the bridging device transmits data with a minimum wireless power.

According to the method, the bridge equipment can automatically adjust the sending power of the equipment according to different positions of the elevator shaft, and the problems that signal saturation bridging is not smooth due to too close equipment intervals and signal strength is weak and bridging is unstable due to too small power configuration of equipment with too far equipment intervals are effectively solved.

Compared with the conventional method, the elevator network bridge product is more flexible, simpler and easier to use by continuously modifying the wireless power value of equipment, the wireless transmitting power of the network bridge is automatically adjusted at different distance positions of the elevator, and the problems of bridge signal saturation and too weak signal are effectively avoided by adjusting the wireless transmitting power of the equipment, so that a transmission network is more stably monitored for users, and the product satisfaction is effectively improved by over 50 percent.

The invention provides an automatic regulation and control method of bridge wireless power, which is applied to the realization of automatic regulation and control of bridge wireless power between a bridge and between the bridge and a base station, and mainly solves the problems of obstructed bridge connection caused by overlarge signal intensity and signal saturation and the problem of too low negotiation rate caused by too weak configuration power and too weak signal.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
