For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The charging gun monitoring method provided by the embodiment of the application is shown in fig. 1 and comprises the following steps:
s101, obtaining a charging gun message of a charging gun, wherein the charging gun message is an insulation detection value of the charging gun;
in one possible embodiment, the step of obtaining a charging gun message of a charging gun, where the charging gun message is an insulation detection value of the charging gun, includes:
and acquiring an insulation detection value of the direct current part of the charging gun and an insulation detection value of the alternating current part of the charging gun.
Illustratively, the whole charging gun detection can be realized by detecting the insulation detection value of the direct-current part of the charging gun and the insulation detection value of the alternating-current part of the charging gun, so that detection omission and danger are avoided.
S102, judging whether the state of the charging gun is normal or not according to the insulation detection value and a preset insulation threshold value;
illustratively, whether the state of the charging gun is normal or not is judged according to the insulation detection value and a preset insulation threshold value in the gun starting process, so that the fault is reflected in time, and loss is avoided.
And S103, controlling the charging gun to stop working if the state of the charging gun is abnormal.
The method comprises the steps of obtaining a charging gun message of a charging gun, wherein the charging gun message is an insulation detection value of the charging gun; judging whether the state of the charging gun is normal or not according to the insulation detection value and a preset insulation threshold value; and if the state of the charging gun is abnormal, controlling the charging gun to stop working. The insulation detection value of the charging gun is compared through the threshold value of the insulation detection value, when the insulation detection value of the charging gun exceeds the threshold value, an alarm is given in time, and early warning of insulation faults is achieved.
In one possible embodiment, the step of determining whether the state of the charging gun is normal according to the insulation detection value and a preset insulation threshold includes:
judging whether the direct current part of the charging gun is normal or not according to the insulation detection value of the direct current part of the charging gun and a preset first insulation threshold value;
and if the direct current part of the charging gun is normal, judging whether the alternating current part of the charging gun is normal according to the insulation detection value of the alternating current part of the charging gun and a preset second insulation threshold value.
Illustratively, when the dc part of the charging gun is abnormal, a field corresponding to the dc part of the charging gun is generated, and when the ac part of the charging gun is abnormal, a field corresponding to the ac part of the charging gun is generated, and the field corresponding to the dc part of the charging gun and the field corresponding to the ac part of the charging gun are stored in a charging message, so that a maintenance worker can conveniently find a fault location.
For example, when the dc part of the charging gun is abnormal, since the insulation requirements corresponding to different positions of the dc part of the charging gun are different, the insulation values corresponding to different positions of the dc part of the charging gun are also different when the dc part of the charging gun is normally operated, and when it is detected that the insulation value at any position of the dc part of the charging gun does not satisfy the corresponding insulation requirements, a fault message corresponding to a fault position of the dc part of the charging gun is generated according to the fault position of the dc part of the charging gun;
similarly, when the alternating current part of the charging gun is abnormal, because the insulation requirements corresponding to different positions of the alternating current part of the charging gun are different, the insulation values corresponding to different positions of the alternating current part of the charging gun are also different when the alternating current part of the charging gun normally works, and when the insulation value of any position of the alternating current part of the charging gun is detected not to meet the corresponding insulation requirement, a fault message corresponding to the fault position of the alternating current part of the charging gun is generated according to the fault position of the alternating current part of the charging gun.
For example, if the charging gun is abnormal due to other reasons except for the abnormal fault of the ac part of the charging gun and the fault of the dc part of the charging gun, a message indicating that the charging gun is normally insulated is generated, thereby avoiding the ineffective work of the maintenance personnel.
In one possible embodiment, before the step of controlling the operation of the charging gun to stop when the state of the charging gun is abnormal, the method includes:
acquiring state data of the charging gun;
and generating a state list based on the state data, wherein the state list includes information data when the charging gun dc part is normal, information data when the charging gun dc part is abnormal, information data when the charging gun ac part is normal, and information data when the charging gun ac part is abnormal.
Illustratively, the state list is generated through the state data, and the information data when the dc part of the charging gun is abnormal and the information data when the ac part of the charging gun is abnormal in the state list are a fault message corresponding to the fault location of the dc part of the charging gun and a fault message corresponding to the fault location of the ac part of the charging gun, so that a maintenance worker can conveniently find the fault cause of the charging gun and accurately determine the fault location.
Illustratively, according to the state list, a maintenance worker can conveniently find the fault reason of the charging gun, and the situation that the maintenance worker judges the fault position mistakenly to cause secondary damage to the charging gun is further avoided.
In one possible embodiment, the step of controlling the operation of the charging gun to be stopped when the state of the charging gun is abnormal includes:
acquiring a data signal of the charging gun with abnormal state;
generating a control signal according to the data signal;
and sending the control signal to the charging gun to stop the charging gun.
In one possible embodiment, the method further comprises:
acquiring a target charging type;
and selecting the preset insulation threshold corresponding to the target charging type according to the target charging type.
Illustratively, different preset insulation thresholds are adopted for different types of targets, so that the applicability of the method in the embodiment of the application is improved.
In a possible implementation manner, the step of selecting the preset insulation threshold corresponding to the target charging type according to the target charging type includes:
establishing a threshold value corresponding table according to a preset charging type and the preset insulation threshold value;
and selecting the preset insulation threshold corresponding to the target charging type according to the target charging type and the threshold corresponding table.
The method comprises the steps of obtaining a charging gun message of a charging gun, wherein the charging gun message is an insulation detection value of the charging gun; judging whether the state of the charging gun is normal or not according to the insulation detection value and a preset insulation threshold value; and if the state of the charging gun is abnormal, controlling the charging gun to stop working. The insulation detection value of the charging gun is compared through the threshold value of the insulation detection value, when the insulation detection value of the charging gun exceeds the threshold value, an alarm is given in time, and early warning of insulation faults is achieved.
In one possible embodiment, the method further comprises:
acquiring temperature information of an alternating current part of the charging gun and a direct current part of the charging gun in real time;
and judging the fault reason of the charging gun according to the temperature information and the charging message, and accurately determining the fault position.
Illustratively, the temperature information of the alternating current part of the charging gun and the temperature information of the direct current part of the charging gun are acquired in real time, the temperature information is compared with a temperature threshold value, when the temperature information of the alternating current part of the charging gun or the direct current part of the charging gun is greater than the temperature threshold value, an alarm is given out, the charging gun is controlled to stop working, the potential safety hazard caused when the charging gun has an insulation fault but the insulation detection value of the charging gun does not exceed the threshold value is avoided, the safety guarantee of the charging gun is increased, and the problem that the temperature of the charging gun is increased and the temperature of a vehicle battery is influenced is also avoided.
For example, as shown in fig. 2, when a non-member and a member use a charging pile to automatically charge, that is, when a gun is started to charge, a monitoring processing center receives a charging message sent by a cloud processing center in real time, and obtains a charging gun message of a charging gun, where the charging gun message is an insulation detection value of the charging gun; judging whether the state of the charging gun is normal or not according to the insulation detection value and a preset insulation threshold value; and if the state of the charging gun is abnormal, namely less than the threshold value, the threshold value defaults to 2000K, an alarm is generated, the fault position is automatically repaired, and when the insulation detection value is greater than or equal to the threshold value, the alarm is automatically recovered after the state is changed into the repaired state.
The method comprises the steps of obtaining a charging gun message of a charging gun, wherein the charging gun message is an insulation detection value of the charging gun; judging whether the state of the charging gun is normal or not according to the insulation detection value and a preset insulation threshold value; and if the state of the charging gun is abnormal, controlling the charging gun to stop working. The insulation detection value of the charging gun is compared through the threshold value of the insulation detection value, when the insulation detection value of the charging gun exceeds the threshold value, an alarm is given in time, and early warning of insulation faults is achieved.
