As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 3, an embodiment of the present application provides a geographic coordinate positioning and time service device 10, which can be applied to an intelligent lighting device such as a lighting brightness control device 11, an intelligent lighting sensor device, an intelligent lighting network device, and an intelligent lighting wireless device. The device comprises: functional circuit board 200 and tail 300. The functional circuit board 200 comprises a coordinate positioning time service module 210, a single chip microcomputer 220 electrically connected with the coordinate positioning time service module 210, and a geographical positioning antenna 230. The coordinate positioning and timing module 210 retrieves the number of satellites at the current position at the current time through the geographic positioning antenna 230, and compares the retrieved number of satellites with a preset number of satellites. The coordinate positioning timing module 210 determines whether to generate and output effective geographic positioning information based on the comparison result.
The geolocation information includes at least location information and time information. The single chip microcomputer 220 is configured to receive the geographical positioning information, process data of the geographical positioning information, and edit the geographical positioning information into a data packet according to a preset rule. One end of the tail wire 300 extends into the housing 100 and is electrically connected to the functional circuit board 200. The other end of the tail line 300 is electrically connected to the lighting control device 11. The single chip microcomputer 220 sends the data packet to the lighting and lightening control device 11 through the tail line 300.
In one embodiment, the body of the functional Circuit Board 200 may be a PCB (Printed Circuit Board) Board. The coordinate positioning time service module 210, the single chip microcomputer 220 and the geographical positioning antenna 230 can be arranged on the PCB, and the integrated design is adopted, so that the field construction and installation can be facilitated. In one embodiment, the single chip microcomputer 220 may be electrically connected to the coordinate positioning and timing module 210 through serial port communication. In one embodiment, the coordinate positioning timing module 210 may use a positioning timing chip with a model number UM220-IV N _ SMD-24P (16 x12.2x2.4mm). In one embodiment, the coordinate positioning and timing module 210 may also adopt other types of positioning and timing chips, such as ubox _ NEO _ 6M.
In one embodiment, the coordinate positioning timing module 210 may be electrically connected to the geolocation antenna 230 through the PCB board (as shown in fig. 4). In one embodiment, when the geographic coordinate positioning and time service device 10 is in operation, first, the coordinate positioning and time service module 210 may continuously search the number of satellites in the sky at the current time through the geographic positioning antenna 230. Wherein the geolocation antenna 230 may be a geolocation ceramic antenna.
Specifically, the satellites searched for at the current position at the current time by the geolocation antenna 230 may include GPS satellites and BDS (beidou) satellites. In one embodiment, the number of retrieved satellites may be compared with a preset number of satellites, and whether valid geolocation information is generated and output is determined based on the comparison result. Specifically, if the number of retrieved satellites is greater than or equal to the preset number of satellites as a comparison result, the coordinate positioning time service module 210 generates effective geographic positioning information and outputs the effective geographic positioning information to the single chip microcomputer 220; if the comparison result is that the number of retrieved satellites is smaller than the preset number of satellites, the coordinate positioning time service module 210 retrieves the number of satellites at the current position at the current time again until the number of retrieved satellites is greater than or equal to the preset number of satellites.
In one embodiment, the preset number of satellites may be set to three. For example, if the coordinate positioning and time service module 210 searches for the number of satellites in the sky at the current position through the geographic positioning antenna 230, the number is: three GPS satellites and two BDS (beidou) satellites; that is, the number of the GPS satellites is the same as the number of the preset satellites, and at this time, the coordinate positioning time service module 210 may generate the effective geographic positioning information according to the GPS satellites and output the effective geographic positioning information to the single chip microcomputer 220. If the number of satellites in the sky at the current time searched by the coordinate positioning time service module 210 through the geographic positioning antenna 230 is: two GPS satellites and four BDS (beidou) satellites; that is, the number of GPS satellites is greater than the number of preset satellites, and at this time, the coordinate positioning and time service module 210 may generate the effective geographic positioning information according to the BDS satellite and output the effective geographic positioning information to the single chip microcomputer 220.
If the number of satellites in the sky at the current time searched by the coordinate positioning time service module 210 through the geographic positioning antenna 230 is: four GPS satellites and four BDS (beidou) satellites; that is, the number of the GPS satellites and the number of the BDS satellites are both greater than the number of the preset satellites, and at this time, the coordinate positioning time service module 210 may generate the effective geographic positioning information according to the BDS satellites or the GPS satellites and output the effective geographic positioning information to the single chip microcomputer 220.
That is, when the number of the GPS satellites is the same as the number of the BDS satellites, and both the numbers of the GPS satellites and the BDS satellites are greater than or equal to the preset number of satellites, the coordinate positioning time service module 210 may generate the effective geographic positioning information according to the satellites that are preferentially searched. For example, the coordinate positioning and time service module 210 preferentially searches for four GPS satellites through the geographic positioning antenna 230, and then searches for four BDS satellites, so that the coordinate positioning and time service module 210 can generate effective geographic positioning information according to the preferentially searched GPS satellites.
In one embodiment, if the coordinate positioning and time service module 210 searches for four GPS satellites and two BDS satellites at the current time through the geographic positioning antenna 230, the coordinate positioning and time service module 210 may generate effective geographic positioning information according to the GPS satellites at this time; at the next moment, the coordinate positioning and time service module 210 searches for four GPS satellites and five BDS satellites through the geographic positioning antenna 230, and at this moment, the coordinate positioning and time service module 210 may generate effective geographic positioning information according to the BDS satellites.
That is, the coordinate positioning and time service module 210 may determine the signal strength of the GPS satellite network and the BDS satellite network according to the number of searched satellites, and preferentially use the satellite network with a stronger signal strength. Meanwhile, in the using process, the switching can be carried out between the GPS satellite network and the BDS satellite network at any time according to the strength of the signal intensity. That is, in use, the accuracy of the geolocation information may increase as the number of search satellites increases. It should be noted that, even though the position of the geographic coordinate positioning service device 10 is not changed in this process, the geographic positioning information provided by the geographic coordinate positioning service device 10 is constantly changing due to the increasing accuracy of the geographic positioning information.
In one embodiment, the geolocation information may include location information and time information. In one embodiment, the geolocation information may also include angle information, and the like. In one embodiment, after the number of satellites searched by the geographic positioning antenna 230 meets the requirement, the coordinate positioning time service module 210 may transmit valuable information (i.e., the geographic positioning information) to the single chip microcomputer 220 through a serial communication line.
After receiving the geographical positioning information, the single chip microcomputer 220 needs to perform data processing on the geographical positioning information. The method specifically comprises the following steps: the single chip microcomputer 220 converts the division value of the geographic coordinate corresponding to the position information in the geographic positioning information into a value of the geographic coordinate and formats the value; simultaneously converting the time value corresponding to the time information into Beijing time and formatting; thereby be convenient for illumination brightening controlgear 11 directly takes, convenient and fast.
For example: the latitude and longitude format initially obtained by the coordinate positioning time service module 210 is as follows: the latitude format is: ddmm. mmmmmmmm, wherein: dd represents degree, mm.mmmmmm represents point; the longitude format is: dddmm. mmmmmmmm, wherein: ddd represents degree, mm. The format of the longitude and latitude is different from the longitude and latitude unit on the positioning map which is widely used at present, so the unit of the longitude and latitude needs to be converted so that the data can be directly used universally. Specifically, the conversion can be performed by the following formula: decimal Degrees + minutes/60+ seconds/3600.
Assume the geographic coordinates raw longitude is: 11355.469591, the above formula is used to convert the data into the following formula: 11355.469591(dddmm. mmmmmm format) 113+55.469591/60 113+0.9244931833 113.9244931833 ° (dd format), the units obtained at this point being degrees.
Assuming that the original latitude of the geographic coordinates is 2246.408912, the above formula transformation is expressed as follows: 2246.408912(ddmm. mmmmmm format) 22+46.408912/60 22+0.773481 22.7734818666 ° (dd format), the units obtained at this time are degrees. Through the logic calculation of the above formula, the single chip microcomputer 220 can obtain the geographic positioning latitude and longitude coordinate information (i.e., the position information) which is obtained by the coordinate positioning time service module 210 and can be directly identified by the lighting brightening control device 11 in units of latitude.
Meanwhile, the single chip microcomputer 220 also needs to convert the acquired time information movement. Specifically, since the beijing time is the absolute time of the beijing time according to the 8 th time zone of the world time, the single chip microcomputer 220 can generate the beijing time by adding 8 hours to the acquired time. So that the acquired time information can be converted into a background time that can be directly used by the lighting control device 11.
After the conversion of the geographical positioning information (i.e., the position information and the time information) is completed, the single chip microcomputer 220 may edit the converted information (i.e., the position information and the time information) into a data packet according to the preset rule. In one embodiment, the format of the data packet may be: RMC _ DATA _12:34:56.00_113.9244931833/E _22.7734818666/N, wherein "$ RMC" is the attribute of the DATA packet, and indicates that the DATA packet is geographical positioning and time service type DATA; "DATA" is an attribute of a DATA packet, indicating that the DATA packet is read-only information DATA; "12: 34: 56.00" is the time information content of the packet, indicating the current time; "113.9244931833/E" is the longitude information in degrees of the geolocation information for the packet; "22.7734818666/N" is latitude information in degrees of the packet's geo-location information. And finishing the compilation of the data packet according to the rule.
In one embodiment, the tail wire 300 is made of a 6-core 3-set twisted single strand copper core wire. The outer layer of the tail wire 300 has a metal mesh-shaped shielding layer for shielding external electromagnetic interference signals. The outmost layer of tail-wire 300 is the restrictive coating, can play effectual guard action to open air sunlight insolate, rainwater soaking etc..
In one embodiment, one end of the tail wire 300 may be electrically connected to the functional circuit board 200 through a connection socket. The other end of the tail wire 300 is a plastic-sealed RJ11 crystal head. When the device is used, the RJ11 crystal plug can be inserted into the RJ11 seat of the lighting and brightening control equipment 11, so that the connection between the geographic coordinate positioning and time service device 10 and the lighting and brightening control equipment 11 is realized, and the device has the advantages of being capable of being plugged and installed at any time and being portable. The singlechip 220 accessible the tail-line 300 will the data packet send to illumination brightening controlgear 11, thereby be convenient for illumination brightening controlgear 11 directly takes, convenient and fast.
In this embodiment, the coordinate positioning and time service module 210, the geographic positioning antenna 230 and the single chip microcomputer 220 are all disposed on the functional circuit board 200, and the integrated design is adopted, so that the field construction and installation can be facilitated. And the data packet is sent to the lighting and brightening control device 11 through the tail wire 300, so that the data packet can be plugged and pulled at any time, and the lighting and brightening control device has the advantages of being convenient to install and carry. Meanwhile, the coordinate positioning time service module 210, the geographical positioning antenna 230 and the single chip microcomputer 220 are matched, so that effective geographical positioning information can be accurately obtained, and the information is subjected to data processing and then is sent to the illumination brightening control equipment 11, so that the illumination brightening control equipment 11 can be directly used, and the operation is convenient and rapid.
In one embodiment, the single chip microcomputer 220 is further configured to obtain, through the tail line 300, operation modes input by the lighting brightening control device 11, where the operation modes include an energy saving mode and an aging mode. In an embodiment, after the geographic coordinate positioning and time service device 10 is connected to the lighting and brightening control device 11 through the tail line 300 and supplies power, the single chip microcomputer 220 first sends its own device attribute information to the lighting and brightening control device 11, and informs the lighting and brightening control device 11 and a geographic coordinate positioning and time service device connected to it. After this step is completed, the lighting brightening control device 11 may send the current working mode to the single chip microcomputer 220 through the tail line 300, so that the functional circuit board 200 inside the geographic coordinate positioning and time service apparatus 10 may adjust itself to the energy saving mode or the time efficiency mode.
For example, if the operating mode acquired by the single chip microcomputer 220 is an energy saving mode, the single chip microcomputer 220 may put the main power consuming modules on the functional circuit board 200 into a sleep state, and put the own power consuming parts into a sleep state. When the single chip microcomputer 220 receives the data request instruction of the lighting and lightening control device 11, the functions of all dormant states are started, then the single chip microcomputer 220 runs at full load, and after information response is completed (namely, the geographical positioning information acquired at the current moment is subjected to data processing and edited into a data packet according to the preset rule to be sent to the lighting and lightening control device 11), the energy-saving mode is entered again, and the next request instruction is waited for and awakened again. Thereby realizing the function of energy saving.
If the working mode acquired by the single chip microcomputer 220 is the aging mode, all the functions on the single chip microcomputer 220 and the functional circuit board 200 are in working states, and at this time, the single chip microcomputer 220 performs data processing uninterruptedly and sends the updated geographical positioning information to the externally connected lighting and brightening control device 11.

Referring to fig. 8, an embodiment of the present application provides a geographic coordinate positioning time service method, which is applied to the geographic coordinate positioning time service device 10 according to any of the above embodiments. The method comprises the following steps:
s102: the number of satellites at the current position at the current time is retrieved through the coordinate positioning time service module 210 based on the geographic positioning antenna 230, the retrieved number of satellites is compared with the preset number of satellites, whether effective geographic positioning information is generated or not is determined based on the comparison result, and the effective geographic positioning information is output, wherein the geographic positioning information at least comprises position information and time information.
In an embodiment, the coordinate positioning and time service module 210 may adopt the positioning and time service chip described in the above embodiments. In one embodiment, the coordinate positioning timing module 210 may first continuously search for the number of satellites in the sky at the current position at the current time based on the geolocation antenna 230. Specifically, the satellites that can be searched for at the current position at the current time by the geolocation antenna 230 may include GPS satellites and BDS (beidou) satellites. In one embodiment, the number of retrieved satellites may be compared with a preset number of satellites, and whether valid geolocation information is generated and output is determined based on the comparison result. The specific comparison method can be the same as that described in the above embodiment.
S104: if the number of the retrieved satellites is greater than or equal to the preset number of satellites as a comparison result, the coordinate positioning time service module 210 generates and outputs the effective geographic positioning information.
During the use process, the switching between the GPS satellite network and the BDS satellite network can be carried out at any time according to the strength of the signal strength. That is, in use, the accuracy of the geolocation information may increase as the number of search satellites increases. It should be noted that, even though the position of the geographic coordinate positioning service device 10 is not changed in this process, the geographic positioning information provided by the geographic coordinate positioning service device 10 is constantly changing due to the increasing accuracy of the geographic positioning information.
S106: the geographical positioning information is received by the single chip microcomputer 220, and after data processing is performed on the geographical positioning information, the processed geographical positioning information is edited into a data packet according to a preset rule, and the data packet is sent to the lighting and brightening control device 11.
In an embodiment, the data processing process of the single chip microcomputer 220 for the geographical positioning information and the process of editing the processed geographical positioning information into a data packet may adopt the manner described in the above embodiments.

The geographic coordinate positioning and time service device 10 starts to work after being adjusted to be in an energy-saving mode.
In the initial stage of the operation, the geographic coordinate positioning and timing device 10 does not send any information to the lighting and lightening control equipment 11. Only after the effective geographic positioning information is generated, the data packet generated by the single chip microcomputer 220 is sent to the lighting and lightening control device 11. After sending the data packet, the single chip microcomputer 220 will set the geo-location module circuit (i.e., the coordinate positioning time service module 210 and the geo-location antenna 230) on the functional circuit board 200 to a sleep mode, and will set other parts of the single chip microcomputer 220 except the communication wakeup unit to a sleep mode, so as to reduce power consumption to the maximum.
In one embodiment, the aging mode refers to: after the single chip microcomputer 220 receives the working mode instruction sent by the lighting and brightening control device 11, if the content of the working mode instruction is to require the geographic coordinate positioning and time service device 10 to work in the aging mode, the functional circuit board 200 in the geographic coordinate positioning and time service device 10 can adjust itself to the aging mode. That is, all the functions of the single chip microcomputer 220 and the functional circuit board 200 are in working states, and at this time, the single chip microcomputer 220 performs data processing uninterruptedly and sends the updated geographical positioning information to the lighting and lightening control device 11 connected to the outside continuously.
In one embodiment, before step S104, the method further comprises: if the comparison result is that the number of the retrieved satellites is smaller than the preset number of satellites, the method returns to the step S102 to retrieve the number of the satellites at the current position at the current moment again until the number of the retrieved satellites is larger than or equal to the preset number of satellites.
To sum up, the coordinate positioning time service module 210, the geographic positioning antenna 230 and the single chip microcomputer 220 are all arranged on the functional circuit board 200, and the integrated design is adopted, so that the field construction and installation can be facilitated. And the data packet is sent to the lighting and brightening control device 11 through the tail wire 300, so that the data packet can be plugged and pulled at any time, and the lighting and brightening control device has the advantages of being convenient to install and carry. Meanwhile, the coordinate positioning time service module 210, the geographic positioning antenna 230 and the single chip microcomputer 220 are matched, effective geographic positioning information can be accurately acquired, and the information is subjected to data processing and then is sent to the illumination brightening control equipment 11, so that the illumination brightening control equipment 11 can be directly taken and used conveniently and quickly.
