All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The current abnormal state of the current battery replacement cabinet is represented by the color or the flicker frequency of an LED lamp on a cabinet body, but the representing mode cannot intuitively allow operation and maintenance personnel to judge the fault position, and when multiple faults occur in the battery replacement cabinet, the fault position is more complicated and more difficult to judge by representing the color or the flicker frequency of the LED lamp.
Therefore, how to intuitively and simply indicate the current abnormal state or states of the power transformation cabinet is a technical problem to be solved urgently in the field.
In order to solve the technical problems, the embodiment of the invention provides a method for diagnosing a fault of a battery replacement cabinet. Fig. 1 is a schematic flow chart of the method for diagnosing a fault of a battery swapping cabinet provided by the invention. As shown in fig. 1, the main implementation body of the method is a battery replacement cabinet fault diagnosis tool, and the method includes:
specifically, after the communication connection between the battery replacement cabinet fault diagnosis tool and the battery replacement cabinet is established, the battery replacement cabinet fault diagnosis tool sends an information acquisition instruction to the battery replacement cabinet at regular time based on a preset time interval, and the information acquisition instruction is used for informing the battery replacement cabinet to collect or acquire current state information of a plurality of monitoring points arranged in a cabinet body of the battery replacement cabinet. And when the battery replacement cabinet receives an information acquisition instruction sent by the battery replacement cabinet fault diagnosis tool, the current state information of each monitoring point is collected or acquired, and the current state information of each monitoring point is sent back to the battery replacement cabinet fault diagnosis tool. And the power conversion cabinet fault diagnosis tool receives the current state information of each monitoring point returned by the power conversion cabinet, and supplies the current state information of each monitoring point to execute the step 120.
It should be noted that each monitoring point set in the power exchange cabinet may be each state monitoring sensor set in the power exchange cabinet, or may be each virtual monitoring point based on a logic monitoring point, for example: the communication state between the main control board and the door panel is monitored, which is not limited in the embodiment of the present invention. Meanwhile, each monitoring point in the power exchange cabinet can be used for monitoring the state of the whole power exchange cabinet and can also be used for monitoring the state of each battery compartment in the power exchange cabinet, and the embodiment of the invention is not limited to this.
specifically, fault diagnosis is performed on each monitoring point based on preset fault diagnosis conditions corresponding to each monitoring point according to the received current state information of each monitoring point, so that a fault diagnosis result of each monitoring point is obtained.
It should be noted that the preset fault diagnosis condition corresponding to each monitoring point may be that the data corresponding to the monitoring point is directly compared with the preset fault diagnosis threshold corresponding to the monitoring point, or that the data corresponding to the predicted point is preprocessed and then compared with the preset fault diagnosis threshold corresponding to the monitoring point, for example, a certain monitoring point may send the count of the count packet to the monitoring point and the count of the count packet received from the monitoring point according to the switch cabinet, so as to calculate the difference between the two, and then compare with the preset fault diagnosis threshold corresponding to the monitoring point, which is not limited in this embodiment of the present invention.
And step 130, displaying the fault diagnosis result of each monitoring point at the corresponding position of each monitoring point in a display mode corresponding to the fault diagnosis result of each monitoring point.
In consideration of the fact that the fault diagnosis results of the monitoring points can be displayed more intuitively on the interface of the battery replacement cabinet fault diagnosis tool, the embodiment of the invention displays the fault diagnosis results of the monitoring points on the interface.
Specifically, according to different display modes of the fault diagnosis results of the monitoring points, the corresponding fault diagnosis results are displayed on the display positions corresponding to the monitoring points.
It should be noted that different display modes of the fault diagnosis result of the monitoring point may correspond to different display modes according to the type of the fault diagnosis result, for example, the fault diagnosis result is abnormal or an alarm may be displayed in a highlighted form or different font colors may be used, and different display modes may also correspond to different display modes based on the type of the monitoring point in combination with the type of the fault diagnosis result, for example, specific prompt information and the display mode of the prompt information may be given according to the type of the monitoring point in combination with the type of the fault diagnosis result, which is not limited in this embodiment of the present invention.
According to the fault diagnosis method for the battery replacement cabinet, provided by the invention, fault diagnosis is carried out on each monitoring point at regular time to obtain a fault diagnosis result, and the fault diagnosis results of each monitoring point are displayed on the screen in different display modes, so that operation and maintenance personnel can locate the fault point intuitively, and the fault processing efficiency of the battery replacement cabinet is improved.
Based on the above embodiment, step 120 includes:
and determining a fault diagnosis result of the monitoring point based on the number of times of the counting packet sent to the monitoring point by the main control board in the power exchange cabinet and the number of times of the counting packet returned from the monitoring point by the main control board aiming at the monitoring point of the communication type, wherein the monitoring point of the communication type at least comprises a door control board communication monitoring point and a charger communication monitoring point.
Specifically, the monitoring points of the communication type represent a type of monitoring points of communication between the main control board of the battery replacement cabinet and the monitoring points, and the monitoring points of the communication type at least include: the monitoring system comprises a door control board communication monitoring point and a charger communication monitoring point, wherein the door control board communication monitoring point represents that the door control board is used as the monitoring point and monitors the communication between a main control board of the battery changing cabinet and the door control board, and the charger communication monitoring point represents that the charger is used as the monitoring point and monitors the communication between the main control board of the battery changing cabinet and the charger, wherein one or more door control board communication monitoring points can be provided, and one or more charger communication monitoring points can be provided. Considering whether the communication between the main switch cabinet control panel and the monitoring point is normal or not, the judgment can be carried out by sending the counting packet times to the monitoring point through the main switch cabinet control panel and the counting packet times sent by the monitoring point and received by the main switch cabinet control panel. Therefore, after receiving the current state information of each monitoring point sent by the power exchange cabinet, fault diagnosis is carried out on each monitoring point in sequence, when the monitoring point is a communication type monitoring point, the fault diagnosis result of the monitoring point is determined according to the difference value between the number of counting packets sent to the monitoring point by the main control board in the power exchange cabinet and the number of counting packets returned from the monitoring point by the main control board, and based on the difference value and the preset fault diagnosis threshold value corresponding to the monitoring point. The preset fault diagnosis threshold may be for a single monitoring point, or may be for each monitoring point of the same type, which is not limited in this embodiment of the present invention.
It should be noted that, a communication count packet between the power switching cabinet main control board and the monitoring point is a count packet sent by the power switching cabinet main control board to the monitoring point at regular time, after receiving the count packet, the monitoring point sends a response count packet to the power switching cabinet main control board, the power switching cabinet main control board records the sending count of the monitoring point, and after receiving the state acquisition instruction sent by the power switching cabinet fault diagnosis tool, the power switching cabinet receives the number of times of the count packet sent by the power switching cabinet main control board to the monitoring point, which is newly recorded by the monitoring point, and the number of times of the count packet received by the power switching cabinet main control board and returned from the monitoring point, as the current state information of the monitoring point, and the current state information of other monitoring points are sent to the power switching cabinet fault diagnosis tool together.
Based on the above embodiment, step 120 includes:
and aiming at the monitoring points of the sensor type, determining the fault diagnosis result of the monitoring points based on the data reported by the sensor, wherein the monitoring points of the sensor type at least comprise: temperature monitoring points and electric quantity monitoring points.

Therefore, after receiving the current state information of each monitoring point sent by the power exchange cabinet, fault diagnosis is sequentially performed on each monitoring point, and when the monitoring point is a sensor type monitoring point, a fault diagnosis result of the monitoring point is determined according to the sensing data of the monitoring point uploaded by the sensor and a preset fault diagnosis threshold corresponding to the monitoring point. The preset fault diagnosis threshold may be for a single monitoring point, or may be for each monitoring point of the same type, which is not limited in this embodiment of the present invention.
It should be noted that the sensor may actively report the current sensing data to the power conversion cabinet, or the power conversion cabinet may send a request for obtaining the sensing data to the sensor to passively report the current sensing data to the power conversion cabinet, which is not limited in this embodiment of the present invention. After receiving the state acquisition instruction sent by the power switching cabinet fault diagnosis tool, the power switching cabinet explains the current state information of the monitoring point of the single sensor type by acquiring the current state corresponding to the monitoring points of the multiple sensor types and the current state information of the monitoring point of the single sensor type, specifically, the power switching cabinet can directly use the latest sensing data of the corresponding monitoring point reported by a certain sensor as the current state information of the monitoring point, and can also send a request for acquiring the sensing data to the sensor, and then use the sensing data returned by the sensor as the current state information of the monitoring point.
