[0102] In one possible implementation, the planned route includes multiple network simulation detection points, and the communication network quality determination device determines whether the network quality of the planned route meets the communication service requirements of the AGV equipment based on the ratio of the target network simulation detection point to the total number of network simulation detection points in the planned route.
[0103] It can be understood that the ratio of the target network simulation detection points to the total number of network simulation detection points in the planned route, that is, the coverage rate of the network simulation detection points in the planned route with a network quality level of a preset level. When the coverage rate is greater than a preset threshold, the communication network quality determination device determines that the network quality of the planned route meets the communication service requirements of the AGV equipment.
[0104] Exemplarily, the above coverage satisfies the following formula 1:
[0105]
[0106] Among them, p Btis the coverage rate of network simulation detection points with a preset network quality level in the planned route; the preset levels are the first and second levels; c Bb is the number of network simulation detection points with the first network quality level, c Bg N is the number of network simulation detection points with the second-level network quality level; Bt is the total number of network simulation detection points in the planned route.

[0111] In one possible implementation, combining Figure 5 ,like Figure 6 As shown, S301, the process of the communication network quality determination device determining the three-dimensional position information of the network simulation detection point of the AGV equipment on the planned route can be specifically implemented through the following S601-S602, which is described in detail below.
[0112] S601. A communication network quality determination device determines the coordinates of each point in a planned route.
[0113] In a possible implementation, the communication network quality determination device uses any corner in the network simulation area as a coordinate origin, constructs a plane rectangular coordinate system, and determines the coordinates of each point in the planned route.
[0114] S602. The communication network quality determination device determines the three-dimensional position information of the network simulation detection point based on the coordinates of each point in the planned route.
[0115] In a possible implementation, the communication network quality determination device converts the coordinates of each point in the planned route into longitude and latitude, and determines the height of the coordinates of each point through real-time measurement, thereby determining the three-dimensional position information of the network simulation detection point.
[0116] For example, Figure 7As shown, Figure 7 A schematic diagram of a plane rectangular coordinate system constructed with any corner in the network simulation area as the origin of the coordinate provided by the embodiment of the present disclosure. a ,y a ) is the farthest point in the X-axis direction in the network simulation area, and the longitude and latitude coordinates of point A are (wx a , wy a ); Point B is the farthest point in the Y-axis direction in the network simulation area, and the longitude and latitude coordinates of point B are (wx b , wy b ), point C (x, y) is any point in the network simulation area, then the longitude and latitude (wx, wy) of point C satisfies the following formulas 2 and 3.
[0117]
[0118] The technical solution provided by the above embodiment can at least bring about the following beneficial effects: the communication network quality determination device first determines the coordinates of each point in the planned route, and then determines the three-dimensional position information of the network simulation detection point through the coordinates of each point in the planned route, so that the communication network quality determination device performs network simulation according to the three-dimensional position information of the network simulation detection point.
[0119] In one possible implementation, combining Figure 6 ,like Figure 8 As shown, the above S302, the process of the communication network quality determination device determining the network quality data of the network simulation detection point according to the three-dimensional position information of the network simulation detection point, can be specifically implemented through the following S801, which is described in detail below.

[0122] In a possible implementation, the communication network quality determination device determines a network simulation detection point in a planned route based on a preset sampling accuracy.
[0123] Exemplarily, the sampling accuracy of the communication network quality determination device is 0.5 meters, that is, the communication network quality determination device determines a network simulation detection point every 0.5 meters based on the coordinates of each point.
[0124] In one possible implementation, the height of the planned route can be divided into three height areas: h0, h1, and h2, where h0 is the height of the AGV equipment receiving antenna; h1 is the height to which the AGV equipment itself can be adjusted; and h2 is the height of the goods loaded in the shelf area. The number of network simulation detection points in the vertical direction can be determined according to the preset sampling accuracy. The number of network simulation detection points is the ratio of the height in the vertical direction to the sampling accuracy. The ratio is rounded up to get the number of network simulation detection points in the vertical direction.
[0125] For example, the integer part of h1 / C is: 01 =[h1 / C], the decimal part is: n 11 =h1\C, if n 11 >0, then the number of network simulation detection points n1=n 01 +1.

[0130] In a possible implementation, the communication network quality determination device obtains three-dimensional feature data of buildings in the currently planned network simulation area, and obtains engineering parameter data of access network equipment planned in the currently planned network simulation area through a network operator.
[0131] Exemplarily, the working parameter data of the access network equipment is shown in Table 5 below.
