In order to solve the defects that in the prior art, a release place is different from an actual release place, release place equipment is carried maliciously by people, the complete machine is carried maliciously during working and the like in the release process of the movable charging pile, the application discloses a movable charging pile geographical position monitoring method which can be applied to a server side and is shown in a figure 1, and the method comprises the following steps:
step S101: recording the obtained position information of the positioning chip in the movable charging pile as an actual position;
in the technical scheme disclosed by the embodiment of the application, a positioning chip is configured in the movable charging pile, the positioning chip is used for positioning the position of the movable charging pile according to a preset period, and sending positioning information to the server when the set period arrives, and the positioning information is used for representing the current position of the movable charging pile;
the periodic frequency of the positioning chip for sending the positioning information may be set by a user according to a user requirement, for example, the periodic frequency is sent every 0.25 hour, or other time lengths.
Step S102: acquiring identification information of the positioning chip;
the method comprises the steps that after the server obtains positioning information sent by a positioning chip, the positioning information is analyzed, identification information contained in the positioning information can be obtained, the identification information can be used as identification information of the positioning chip and identification information of the movable charging piles, the two identification information have the same effect, each movable charging pile and the positioning chip have unique identification information, and the identification information is used for representing the identity of the movable charging pile corresponding to address information.
Step S103: acquiring a target position matched with the identification information of the positioning chip from a preset database;
after the identification information is obtained, searching in a preset database to obtain a target position of the movable charging pile corresponding to the identification information, wherein the target position is a standard position of the movable charging pile;
step S104: judging whether the coordinate difference value of the actual position and the target position is within an allowable error range;
in this step, the actual position corresponding to the current moment of the movable charging pile is compared with the target position, and whether the movable charging pile moves is judged according to the comparison result, of course, when the positioning chip performs positioning, due to various reasons, a certain deviation may exist between the equipotential result and the actual position, in order to prevent misjudgment, an allowable error may be preset in the scheme, and as long as the coordinate difference between the actual position and the target position is within the allowable error range, it is indicated that the movable charging pile has not moved;
step S105: if the current is not within the allowable error range, sending an alarm signal to the movable charging pile end to trigger an alarm circuit in the movable charging pile to alarm;
in the step, when the coordinate difference value between the actual position and the target position exceeds the allowable error range, the movable charging pile is determined to move, and at the moment, an alarm signal is generated and sent to the movable charging pile through a wireless network so as to trigger the alarm circuit to execute an alarm action.
In the technical solution disclosed in the above embodiment of the present application, the server obtains the position information uploaded by the movable charging pile in a wireless manner, the server analyzes the position information to obtain the identification information of a behavior chip contained in the position information, uses the identification information as the identification information of the movable charging pile, obtains a target position matched with the identification information of the positioning chip from a preset database, where the target position is the target position of the movable charging pile, then determines whether the coordinate difference between the actual position and the target position is within an allowable error range, if so, indicates that the movable charging pile is not moved, and if not, sends an alarm signal to the movable charging pile end to trigger an alarm circuit in the movable charging pile to alarm, the movable charging pile real-time monitoring system has the advantages that the movable charging pile real-time monitoring of the coordinate position is achieved, and the phenomenon that the movable charging pile is carried by people maliciously is prevented.

step S203: when the time difference is greater than the second preset time length, judging whether the server acquires a first preset signal uploaded by the charging pile end;
in the scheme, a second preset time length is preset, in a conventional state, when the positioning information output by the positioning chip is not acquired continuously for the second preset time length, the server actively sends an alarm signal to the movable charging pile corresponding to the behavior chip, and certainly before the alarm signal is sent, whether the situation that the positioning information is not received is normal needs to be judged, so that the server also needs to judge whether a first preset signal uploaded by the charging pile end is acquired, certainly, the first preset signal has a validity period, and the first preset signal fails after the validity period elapses; and when the first preset signal is obtained and is effective, the alarm signal is not issued to the movable charging pile. When a first preset signal matched with the movable charging pile needing to be alarmed is not obtained, the movable charging pile is indicated to be abnormal, and step S205 is executed;
step S204: when the judgment server acquires a first preset signal uploaded by the charging pile end, judging whether the time difference between the first time and the current time is greater than a first preset time, if not, performing an alarm action, otherwise, executing the step S205;
further, in this step, whether the first preset signal is valid may be determined in a manner of a first preset duration that is originally set, where the first preset duration is a preset duration, and in this step, by comparing a duration that the positioning signal is not obtained with the first preset duration, whether the first preset signal is valid is determined according to a comparison result, that is, if the positioning information sent by the positioning chip is not obtained within a long period of time (the first preset duration), it indicates that the first preset signal is an invalid signal.
