Detailed Description
In order to make the purpose, technical solution and technical effects of the present application clearer and clearer, the following further describes the present application in detail, and it should be understood that the specific embodiments described herein are only used for explaining the present application, and are not used for limiting the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the positioning system of the present application. In the present embodiment, the positioning system 10 includes an automobile 11, an in-vehicle charger 12, and a smart terminal 13. In the actual use process, the vehicle-mounted charger 12 is connected with the cigarette lighting port of the automobile 11 to obtain the voltage of the cigarette lighting port of the automobile 11; the in-vehicle charger 12 is connected to the smart terminal 13 to perform communication. In one embodiment, the vehicle charger 12 and the intelligent terminal 13 are connected through a wireless network, wherein the wireless network includes any one of bluetooth, wifi network or zigbee network. In a preferred embodiment, the vehicle charger 12 is connected to the intelligent terminal 13 via bluetooth.
The vehicle-mounted charger 12 is used for detecting the voltage of a cigarette lighting port of the automobile 11 and judging whether the voltage of the cigarette lighting port is lower than a preset threshold value or not; if the voltage of the cigarette lighting port is lower than the preset threshold value, the vehicle-mounted charger 12 sends a positioning prompt instruction to the intelligent terminal 13. The intelligent terminal 13 receives the positioning prompt instruction, and determines and records the parking position of the automobile 11 according to the positioning prompt instruction. In an optional embodiment, the positioning function of the intelligent terminal 13 is in an on state, so that the intelligent terminal 13 records position information at any time, where the position information is associated with the time, then indexes and determines the geographical position of the intelligent terminal 13 when the positioning prompt instruction is received according to the time when the positioning prompt instruction is received, and marks the geographical position of the intelligent terminal 13 when the positioning prompt instruction is received as the parking position of the automobile 11. In another embodiment, in order to save power consumption, when the intelligent terminal 13 receives the positioning prompt instruction, the intelligent terminal 13 is triggered to start the positioning function, and at the time point when the positioning function of the intelligent terminal 13 is started, the position information of the intelligent terminal 13 at that time is immediately acquired and recorded, and the position information is marked as the parking position of the automobile 11. Because the user needs certain time from flameout parking to getting off the vehicle, the parking position of the vehicle is positioned by utilizing the time, the high-precision positioning can be realized, and the power consumption can be saved.
For clearly explaining the positioning method of the automobile, please refer to fig. 2, and fig. 2 is a schematic flow chart of an embodiment of the positioning method of the present application. Referring to fig. 1, the positioning method of the vehicle according to the present embodiment is performed from the perspective of the in-vehicle charger 12.
Step 201: the vehicle-mounted charger detects the voltage of a cigarette lighting port of the automobile.
In the present embodiment, the in-vehicle charger detects the ignition port voltage of the automobile by the voltage detection circuit thereof.
Step 202: and judging whether the voltage of the cigarette lighting port is lower than a preset threshold value or not.
In one application scenario, the vehicle-mounted charger obtains the working voltage through a cigarette lighting port of the automobile so as to establish network connection with the intelligent terminal. When an engine of an automobile is flamed out, a cigarette lighting port of the automobile can be directly powered down, namely, the cigarette lighting port is powered off, or the quality of power cannot meet the requirement, so that the vehicle-mounted charger cannot work. When the vehicle-mounted charger detects that the cigarette lighting port of the automobile is powered off, the vehicle-mounted charger is disconnected with the intelligent terminal through the network, so that after the intelligent terminal detects that the intelligent terminal is disconnected with the vehicle-mounted charger, the position information of the intelligent terminal is recorded, and the geographical position where the intelligent terminal is located when the intelligent terminal is detected to be disconnected with the vehicle-mounted charger through the network is marked as the parking position of the automobile. The user can determine the parking position of the automobile through the position information.
In other application scenarios, after some automobile engines are flamed out, the cigarette lighter is not powered down, and only when a user holds the intelligent terminal and leaves the connection range of the intelligent terminal and the vehicle-mounted charger, the intelligent terminal is triggered to record position information after the intelligent terminal is disconnected with the vehicle-mounted charger, so that the position information has a large error, and the parking position of the automobile is inaccurate.
Although some automobiles cannot be completely powered down after flameout and parking, the power supply source of the voltage of the ignition port is replaced by the storage battery of the automobile through the engine of the automobile, so that the voltage of the ignition port is slightly reduced, therefore, the vehicle-mounted charger can determine the state of the engine of the automobile according to the change of the voltage of the ignition port, and further determine whether the automobile is flameout and parked.
Specifically, the vehicle-mounted charger detects whether the voltage of the cigarette lighting port of the automobile slightly drops through the voltage detection circuit of the vehicle-mounted charger, and if the voltage of the cigarette lighting port of the automobile slightly drops, the vehicle-mounted charger further detects the voltage of the cigarette lighting port of the automobile and judges whether the voltage of the cigarette lighting port is lower than a preset threshold value.
Step 203: if the voltage of the cigarette lighting port is lower than the preset threshold value, the vehicle-mounted charger sends a positioning prompt instruction to the intelligent terminal, so that the intelligent terminal receives the positioning prompt instruction, and the parking position of the automobile is determined and recorded according to the positioning prompt instruction.
At present, the battery voltages corresponding to different types of automobiles are different. For example, the battery voltage of some automobiles is 12V, and the battery voltage of other automobiles is 24V. Here, 12V and 24V correspond to the rated values of the battery voltage.
Wherein, the voltage of the cigarette lighting port is the voltage which is output outwards by the automobile through the cigarette lighting port. Specifically, when the engine of the automobile does not work, the voltage of the cigarette lighting port is determined by the voltage of the battery of the automobile; when the engine of the automobile works, the voltage of the ignition port is determined by the engine of the automobile.
In the actual use process, the preset threshold values corresponding to different types of automobiles are different. The vehicle-mounted charger needs to determine the type of the battery of the automobile according to the voltage of the cigarette lighting port, and further determines a preset threshold, wherein the type of the battery of the automobile is determined by the voltage of the battery of the automobile, and the preset threshold is associated with the voltage of the battery of the automobile. Specifically, the storage battery type of car is different, and the voltage of some cigarette mouth voltage output also can be different, and although when the car was in different states, the voltage of some cigarette mouth also differed, nevertheless, the storage battery of different grade type no matter in what kind of state, the same condition of some cigarette mouth voltage generally can not appear, so, on-vehicle charger can confirm the storage battery type according to some cigarette mouth voltage value, and then confirms the corresponding threshold value of predetermineeing.
In one embodiment, when the rated voltage of the battery of the automobile is 12V, the preset threshold value is 12.8V. If the voltage of the cigarette lighting port is detected to be lower than 12.8V, the engine of the automobile can be determined not to work at the moment, and the voltage of the cigarette lighting port is determined by the voltage of a storage battery of the automobile; if the voltage of the ignition port is detected to be not lower than 12.8V, the engine of the automobile is determined to be operated at the moment, and the voltage of the ignition port is determined by the engine of the automobile.
In another embodiment, the preset threshold is 26.2V when the battery of the automobile is rated at 24V. If the voltage of the cigarette lighting port is detected to be lower than 26.2V, the engine of the automobile can be determined not to work at the moment, and the voltage of the cigarette lighting port is determined by the voltage of a storage battery of the automobile; if the voltage of the ignition port is detected to be not lower than 26.2V, the engine of the automobile is determined to be operated at the moment, and the voltage of the ignition port is determined by the engine of the automobile.
In the embodiment, if the voltage of the cigarette lighting port is lower than the preset threshold, the vehicle-mounted charger sends a positioning prompt instruction to the intelligent terminal, so that the intelligent terminal receives the positioning prompt instruction, and determines and records the parking position of the automobile according to the positioning prompt instruction. In an optional implementation mode, the positioning function of the intelligent terminal is in an on state, so that the intelligent terminal records position information at any time, wherein the position information is associated with the time, then the geographical position of the intelligent terminal when the positioning prompt instruction is received is indexed and determined according to the time when the positioning prompt instruction is received, and the geographical position of the intelligent terminal when the positioning prompt instruction is received is marked as a parking position of an automobile. In another embodiment, in order to save power consumption, when the intelligent terminal receives a positioning prompt instruction, the intelligent terminal is triggered to start the positioning function, and at the time point when the positioning function of the intelligent terminal is started, the position information of the intelligent terminal at the time is immediately acquired and recorded, and the position information is marked as the parking position of the automobile. Because the user needs certain time from flameout parking to getting off the vehicle, the parking position of the vehicle is positioned by utilizing the time, the high-precision positioning can be realized, and the power consumption can be saved.
When the storage battery is damaged or over-discharged, the voltage of the storage battery is in a low or over-low state, and the condition of inaccurate detection can occur if the state of the automobile engine is determined by the voltage of the cigarette lighting port. In order to improve the detection accuracy, in another embodiment, the vehicle-mounted charger detects and judges whether the cigarette lighting voltage of the automobile is within a preset range, wherein the maximum value of the preset range is a preset threshold value. If the engine is in the preset range, the engine of the automobile does not work, and the automobile is shut down.
In one embodiment, when the battery voltage of the automobile is 12V, the preset range is 11.8V-12.8V. That is, when it is detected that the ignition port voltage falls between 11.8V and 12.8V, it is determined that the engine of the vehicle is not operated at that time, and the vehicle is shut down.
In another embodiment, when the battery voltage of the automobile is 24V, the preset range is 23V-26.2V. That is, when it is detected that the ignition port voltage falls between 23V and 26.2V, it is determined that the engine of the vehicle is not operated at that time, and the vehicle stops.
In this embodiment, if the voltage of the cigarette lighting port is within the preset range, the vehicle-mounted charger sends a positioning prompt instruction to the intelligent terminal, so that the intelligent terminal receives the positioning prompt instruction, records the position information of the intelligent terminal according to the positioning prompt instruction, and marks the geographic position where the intelligent terminal is located when the positioning prompt instruction is received as the parking position of the automobile.
Different from the prior art, the positioning method comprises the following steps: detecting and judging whether the voltage of a cigarette lighting port of the automobile is lower than a preset threshold value by the vehicle-mounted charger; if the voltage of the cigarette lighting port is lower than the preset threshold value, the vehicle-mounted charger sends a positioning prompt instruction to the intelligent terminal, so that the intelligent terminal receives the positioning prompt instruction, and the parking position of the automobile is determined and recorded according to the positioning prompt instruction. The vehicle-mounted charger takes the voltage change of the cigarette lighting port of the automobile as a judgment basis for detecting the state of the engine, when the voltage of the cigarette lighting port is lower than a preset threshold value, the engine is judged to be flameout, namely, the automobile stops, the intelligent terminal is informed to determine and record the parking position of the automobile, and the positioning precision of the parking position of the automobile can be improved.

Meanwhile, the intelligent terminal marks the geographic position as the parking position of the automobile, and a user can navigate through the specific application program to quickly reach the marked parking position of the automobile, so that the automobile can be quickly found.
Because, some cars after the engine stalls, the voltage of car ignition mouth can fall the electricity completely, and then makes on-vehicle charger outage, and intelligent terminal can be with on-vehicle charger disconnect-type. In order to ensure that the parking position of a vehicle of this type can be determined. In step 301: the method comprises the following steps that before the intelligent terminal receives a positioning prompt instruction sent by the vehicle-mounted charger: the intelligent terminal detects whether a positioning prompt instruction sent by the vehicle-mounted charger is received or not according to a preset frequency; and if the positioning prompt instruction is not received, judging whether the intelligent terminal is disconnected with the vehicle-mounted charger. And if the connection is disconnected, acquiring the geographic position of the current intelligent terminal, and marking the geographic position as the parking position of the automobile.

If the positioning prompt instruction is received, execute step 302: and detecting the geographical position of the intelligent terminal when the positioning prompt instruction is received, and marking the geographical position as the parking position of the automobile.
