Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of embodiments in many different forms than those described herein and those skilled in the art will be able to make similar modifications without departing from the spirit of the application and it is therefore not intended to be limited to the embodiments disclosed below.
Referring to fig. 1, the present application provides a signal coverage method applied to an underground substation. The method comprises the following steps:
s100, acquiring a region to be covered and establishing a two-dimensional grid plane corresponding to the region to be covered.
In an embodiment, the step S100 is specifically to first obtain a two-dimensional plane map of the area to be covered, and discretize the area to be covered into a two-dimensional grid plane according to the maximum length and width of the two-dimensional plane map. The extent of the two-dimensional grid plane is limited to complete coverage of the entire building area of the underground substation. It can be understood that the discretized step size Sgrid is 1.5m, so that the requirement of coverage evaluation accuracy can be met, and the complexity of calculation cannot be obviously increased. After the two-dimensional grid plane is generated, points outside a drawing of the transformer substation are removed according to a ray casting method, and each point on the two-dimensional grid plane is regarded as a signal receiving point. If the position point of the signal receiving point is RmRepresents, then { RmAnd |0 is less than or equal to M and less than or equal to M }, wherein M is the number of the maximum signal receiving points in the two-dimensional grid plane, and M is the number of the signal receiving points.
S200, determining the minimum number N of the antennas in the area to be covered and determining the set position V of the antennas by iterative computation based on the two-dimensional grid planeNWherein, the VNIndicating the set position of any one of the antennas.
The minimum number N of antennas in the area to be covered is the minimum number N of antennas that need to be arranged in the area to be covered when the signal completely covers the area to be covered. The set position V of the antennaNI.e. the set position of any one antenna in the area to be covered. The staff can obtain the minimum number N of the antennas and the set position V of the antennas by arranging and calculating on the two-dimensional grid planeN. It can be understood that in the actual process of performing the operation comparison, the operator needs to use the iterative algorithm to perform the continuous analysis comparison. The analysis comparison is to analyze the number N of the antennas and the set position V of the antennasNAnd the signal coverage of the antenna, and comparing whether the signal coverage is less than the desired coverage. If the signal coverage rate is less than the expected coverage rate, continuing to increase the number N of the antennas or changing the set position V of the antennasNOr simultaneously changing the number N of the antennas and the set position V of the antennasNUntil the signal coverage is greater than the desired coverage. When the signal coverage rate is larger than the expected coverage rate, outputting the number N of the antennas and the set position V of the antennas at the momentNAt this time, the number N of antennas is the minimum number of antennas in the area to be covered.

The internet access request refers to a fourth Generation communication technology, namely 4G (the 4Generation mobile communication technology) communication, and the corresponding signal field strength is more than-85 dBm. Namely, the PrGreater than-75 dBm and-85 dBm need to be satisfied.
S400, if the signal field intensity PrIf the standard strength is not reached, increasing the set position V of the antenna which does not reach the standard strengthNNumber of antennas N, and update the VN；

If the V does not meet the requirement of 4G callNGreater than the V that does not meet 2G call requirementsNIncreasing the V which does not meet the requirement of the 4G callNThe number of antennas N, and update the VN. The S400 can simultaneously carry out one-time integration optimization on the 2G and the 4G, can simultaneously calculate the optimized layout of the 2G and the 4G, and gives a compromise scheme, namely, both the 2G and the 4G can be considered.
S500, executing the steps from S300 to S400 until the set position VNSignal field strength PrReaching the standard strength, and outputting the number N of the antennas and the set position V of the antennasN。
It is understood that, in practical operation, the steps S300 to S400 need to be repeatedly executed until the signal intensity of the whole area to be covered reaches the standard intensity, and more specifically, the set position VNSignal strength P ofrReaching the standard strength. Wherein, the VNIndicating the set position of any one antenna, it will be appreciated that the signal strength P isrIs the signal strength at any antenna setting location.

Furthermore, after the number and the arrangement positions of the antennas are calculated, the signal strength P of the antenna arrangement positions can be measuredrAnd (6) performing calculation. If the signal strength P isrNot reaching the standard strength, i.e. PrIt is not enough to provide the workers of the underground substation to communicate with the ground or the outside and to transmit network data. Then, the number N of antennas at the set position of the antennas which do not reach the standard strength is increased until the set position VNSignal strength P ofrReaching the standard strength. The signal coverage method provided by the application is characterized in that a two-dimensional grid plane corresponding to a region to be covered in an underground substation is established, and the minimum number of antennas to be arranged and the set positions of the antennas are determined through the two-dimensional grid plane. In addition, the signal coverage method provided by the application can also increase the number of antennas in a weak signal position according to the call requirement and the network requirement.
