Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a street lamp positioning method. As shown in fig. 1, the street lamp positioning method includes the following steps:
step S1: and acquiring distances between the target street lamp and any three street lamps with the GPS position information and acquiring the GPS positioning data of any three street lamps.
For example, the target street lamp may be a street lamp that has failed and needs to be repaired. The target street lamp and any three street lamps are located in the area of the preset range. For example, the street lamps can be located in the same urban and rural combination area. The target street lamp can be identified by the ID of the target street lamp. Any three street lamps can be three street lamps with GPS position information which are randomly encountered by a worker in the process of reaching a target street lamp. Three street lamps with GPS position information form a positioning set. The GPS positioning data of each street lamp in the three street lamps is obtained through an external GPS module, or is from GPS positioning data which is internally stored in advance, or is obtained by a GPS module which is integrated by the street lamp. The street lamps are in communication connection, so that data of peripheral devices can be recorded for verification. The GPS module can communicate with a Beidou satellite or a GPS system and the like to acquire corresponding GPS positioning data of the street lamp. In practice, the GPS module may send the acquired GPS positioning data to the server.
Wherein, the GPS location data of every street lamp obtains through external GPS module, includes: the GPS module is connected to a street lamp through a Bluetooth or cable interface to transmit GPS positioning data. It should be understood that when such an external GPS module is used, if the external GPS module is moving (i.e., not mounted on a street lamp), the external GPS module does not perform positioning and broadcasting, thereby avoiding GPS positioning drift.
Specifically, the distances between the target street lamp and any three street lamps with GPS position information may be acquired as follows:
and obtaining the distances between the target street lamp and any three street lamps according to the intensity of the radio frequency signals respectively sent by any three street lamps received by the target street lamp.
Specifically, the positioning device can be installed on any three street lamps. In particular, the positioning device may be secured to the pole of the street light by magnetic force or straps so that the positioning device does not shift position during positioning. For convenience of use, the positioning device may include: a status indication module (e.g., LED, LCD, etc.) and a status recognition sensor (typically a three-axis accelerometer) to identify and indicate to the staff member their own working status. The positioning device may also include a battery to power itself.
The positioning device may include: the short-range radio frequency communication module can be 2.4G or 433M. It should be understood that the street lamps in the embodiments of the present invention are all installed with modules capable of communicating with the short-range rf communication module. The RSSI (received Signal Strength indication) technology is adopted for measuring the distance, and the distance measurement theory is as follows: according to the principle that radio waves or sound waves are transmitted in a medium and the signal power is attenuated along with the propagation distance, the distance between nodes can be calculated through an attenuation model between signals and the distance according to the transmitting power of known signals of beacon nodes and the signal power received by the nodes. The RSSI technique is well known to those skilled in the art and will not be described in detail herein. The positioning device can send the collected data to the server, and the server carries out corresponding calculation to obtain the distance.

The coordinates of the common intersection point a can be calculated by a three-point positioning method, which is well known to those skilled in the art and will not be described herein.
(4) If the circumferences of the first circle, the second circle and the third circle do not have a common intersection point, and the first circle, the second circle and the third circle have a common area overlapped with each other, the coordinates of the three intersection points of the common area are calculated.
