step A3), after receiving the entering information, the platform pushes the parking status update information to the charging terminal;
step A4) the charging terminal actively requests the parking list interface after receiving the update message of the parking status, modifies the corresponding parking status, and calculates the difference between the current time and the last payment time;
step A5) judging whether the difference between the current time and the last payment time is in the non-evidence-obtaining time range, if so, displaying countdown and shielding an evidence-obtaining entrance, and if not, modifying the berth state of the database and obtaining evidence.
Preferably, the berth list module corresponding to the berth list interface stores a countdown variable with a city as an ID by using a ConcurretHashMap.
Preferably, the modifying the berth state in the step a1) includes the following specific steps:
step B1) the platform pushes the parking update status message to the charging terminal through MQTT;
step B2), after receiving the message notification, the charging terminal actively requests the parking list interface to obtain the latest parking state, and modifies the corresponding parking to 'idle'.
Preferably, the charging terminal requests the parking list interface again each time it receives the parking status update message.
Compared with the prior art, the invention has the following advantages and beneficial effects:
the invention records the last payment time of the berth through the platform, when the charging terminal requests a berth list interface, the platform sends the last payment time corresponding to the berth to the charging terminal, the charging terminal calculates the difference between the current time and the last payment time, if the time is in non-evidence-obtaining time, the current berth state is marked specially, and the countdown is displayed on the current berth, at the moment, the evidence-obtaining entrance is shielded, and the berth state is modified and evidence can be obtained if the time exceeds the non-evidence-obtaining time. Compared with the traditional mobile charging terminal, the method and the system have the advantages that in order submission, order data are submitted to the server in a segmented mode, time-consuming data are uploaded and put to the background process for asynchronous submission, a failure retransmission mechanism is realized, the situation that submission fails all the time and the user is blocked under the condition that the network environment is not ideal is avoided, charging and working efficiency are greatly improved, abnormal orders are greatly reduced, the cost for manually processing abnormal orders is saved, the experience of the user is improved, and applicability and practicability are improved.

Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
referring to fig. 1, a method for avoiding an abnormal order in a roadside parking lot based on NB geomagnetism includes the following steps:
step A1) the vehicle owner can pay by cash, code scanning or bank card, the platform receives the payment request, the order is finished, the platform stores the payment time, the corresponding berth state of the database is pushed to the charging terminal, and the charging terminal modifies the berth state to 'idle'. The specific steps for modifying the berth state are as follows: step B1) platform pushes the berth update status message to the charging terminal through MQTT, step B2) after the charging terminal receives the message notice, actively request the berth list interface to obtain the latest berth status, and modify the corresponding berth to be idle.
Step A2), the vehicle owner gets out, due to the road objective factor, the vehicle can go forward-backward for many times on the current parking position, the geomagnetic sensor senses the vehicle, and the vehicle entering information is pushed to the platform.
Step A3), after receiving the information, the platform modifies the corresponding parking status in the database into 'no evidence of vehicle entering', and meanwhile, pushes the parking status update information to the charging terminal through MQTT.
Step A4) after the charging terminal receives the update message of the parking position state, the charging terminal actively requests the parking position list interface, modifies the corresponding parking position into 'no evidence obtained when the vehicle enters', and calculates the difference between the current time and the last payment time.
Step A5) judging whether the difference between the current time and the last payment time is in the non-evidence-obtaining time range (for example, 5 minutes), if so, displaying countdown and shielding an evidence-obtaining entrance, marking the parking position state as' vehicle entering is not obtained, simultaneously displaying countdown on the parking position, updating the remaining countdown time every 1 second, and if not, modifying the parking position state of the database and obtaining evidence.
