Embodiment 1

[0072] This embodiment provides a satellite positioning circuit. The satellite positioning circuit of this embodiment can be applied to terminal devices to be positioned, such as high-definition cameras, cameras or camera guns, and mobile electronic devices such as smart phones.

[0073] The satellite positioning circuit includes: a BD / GPS positioning antenna, an IC positioning module U1 and a signal output circuit, and the BD / GPS positioning antenna, IC positioning module U1 and the signal output circuit are connected in series in sequence. The BD / GPS positioning antenna is used to receive the positioning signal from the satellite, and send the positioning signal to the IC positioning module; the IC positioning module U1 receives the positioning signal, and is equipped with a related calculation program, which is used to calculate the position to be positioned according to the received positioning signal The location data of the terminal device, the location data includes thre...

Embodiment 2

[0079] This embodiment provides a positioning camera. The positioning camera includes: a camera body and a satellite positioning circuit, and the satellite positioning circuit is installed in the camera body. The satellite positioning circuit is specifically as described in Embodiment 1, and will not be described in detail in this example. The positioning camera also includes: a fault detection circuit installed in the camera body; the fault detection circuit includes: a detection signal input branch, a calculation branch, a fault signal output branch, a feedback sensitivity adjustment branch, a second A filter branch and a pair of ground branches; wherein, the detection signal input branch is connected in series with the operation branch, the feedback sensitivity adjustment branch and the ground branch; the operation branch is respectively connected in series with the feedback sensitivity adjustment branch and the second filter branch and the fault signal output branch; the f...

Embodiment 3

[0089] This embodiment provides a camera positioning method. Based on the satellite positioning circuit described in Embodiment 1 and the positioning camera described in Embodiment 2, the camera positioning method of this embodiment includes the following steps:

[0090] BD / GPS positioning antenna receives positioning signals from satellites;

[0091] The IC positioning module calculates the position data of the camera according to the positioning signal, and the position data includes three-dimensional coordinates or latitude and longitude;

[0092] The signal output circuit outputs position data.

[0093] In the camera positioning method, the distance formula triangle in the three-dimensional coordinates is used for positioning. Specifically, the program in the IC positioning module calculates the three-dimensional coordinates of the camera to be positioned or converts the three-dimensional coordinates into longitude and latitude. When calculating the three-dimensional coor...

Abstract

The invention discloses a satellite positioning circuit, a positioning camera and a camera positioning method. The satellite positioning circuit applied to a to-be-located terminal device comprises aBD / GPS positioning antenna, an IC positioning module, and a signal output circuit; the BD / GPS positioning antenna is used for receiving a positioning signal from a satellite; the IC positioning moduleis used for calculating location data of the to-be-located terminal device based on the positioning signal, wherein the location data include a three-dimensional coordinates or a latitude and a longitude; and the signal output circuit is used for outputting the location data. The BD / GPS positioning antenna, the IC positioning module and the signal output circuit are connected in series. Accordingto the invention, when the satellite positioning circuit is applied to the to-be-located terminal device like a front-end high-definition camera, a camera or a camera gun, the terminal device can belocated accurately to provide accurate locations of front-end devices of safety city, public safety and security and protection equipment.

Description

technical field [0001] The invention relates to the technical fields of safe city, public safety and security equipment, in particular to a satellite positioning circuit, a positioning camera and a camera positioning method applied to a front-end high-definition camera, a camera or a camera gun. Background technique [0002] At present, the image front-end equipment of safe cities, public safety and security equipment in the market, such as front-end high-definition cameras, cameras or camera guns, does not have the positioning function, and the security of the front-end equipment cannot be prevented. Once the front-end equipment is stolen, it will be damaged. The real-time positioning and search of the location cannot be realized, which may easily cause unnecessary economic losses. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a satellite positioning circuit, a positioning camera and a camera positioning met...
