[0021] If not, the fuel vehicle or the spare vehicle of the non-target vehicle group will be the replacement vehicle.

[0022] In a preferred embodiment, the present application may be further configured such that, if the charging mode is unsaturated, the determination of the replacement vehicle based on the vehicle status of the transport vehicle and the non-transport vehicle includes:

[0023] If the warning vehicle is a spare vehicle and the non-transport vehicle has completed charging, the replacement vehicle will be the non-transport vehicle;

[0024] If the warning vehicle is a spare vehicle and the non-transport vehicle has not completed charging, the replacement vehicle is a fuel vehicle or a spare vehicle of the non-target vehicle group;

[0025] If the warning vehicle is the main vehicle and the non-transport vehicle is the backup vehicle, the replacement vehicle is determined based on the vehicle status and current power of the non-transport vehicle;

[0026] If the warning vehicle is the main vehicle and the non-transport vehicle is the main vehicle, the charging time of the non-transport vehicle is obtained, and the replacement vehicle is determined based on the charging time of the non-transport vehicle.

[0046] In summary, this application includes the following beneficial technical effects:

[0047] In order to ensure that the transportation volume of mineral materials meets production needs, it is necessary to ensure that a sufficient number of transport vehicles are running at the same time. However, the transport vehicles need to ensure sufficient power during the transportation process. In order to avoid concentrated charging of the transport vehicles, a reasonable charging mode needs to be adopted. Therefore, it is necessary to obtain the current charging mode of the target vehicle group and monitor it according to the current charging mode; then obtain the vehicle status, vehicle attributes and power of the transport vehicles and non-transport vehicles; different charging modes have different consideration dimensions for transport vehicles and non-transport vehicles, so it is necessary to determine the replacement vehicle based on at least one of the vehicle status, vehicle attributes and current power of the transport vehicles and non-transport vehicles to better adapt to different charging modes, so as to obtain more accurate replacement vehicles, and then use accurate replacement vehicles and early warning vehicles to generate replacement signals. Compared with the dispatching staff determining the replacement vehicle, the present application determines the replacement vehicle from different dimensions under different charging modes, so as to effectively improve the accuracy of the replacement vehicle determination.

[0051] The following is combined with Figure 1 To Attachment Figure 3 This application is described in further detail.

[0052] After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of this application.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0055] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0056] The embodiment of the present application takes a mining company in Tangshan as an example, which is equipped with 28 transport vehicles, including 12 transport vehicles with a load capacity of 70 tons and a battery capacity of 525kwh, 8 transport vehicles with a load capacity of 60 tons and a battery capacity of 422kwh, 8 transport vehicles with a load capacity of 60 tons and a battery capacity of 350kwh, and several fuel vehicles; based on the actual transportation needs, it is necessary to ensure that 21 transport vehicles participate in the transportation at the same time, so they are divided into seven vehicle groups, each of which has four transport vehicles. The four transport vehicles participate in the transportation according to the principle of "three main vehicles and one spare vehicle", that is, three main vehicles and one spare vehicle. When the four transport vehicles are fully charged, the three main vehicles will participate in the transportation first, and the spare vehicles will wait. Furthermore, in an embodiment of the present application, in order to better meet the transportation demand, four systems are set up, including: a main system, a 1350 system, a 900 system and a 750 system, wherein the first transportation demand corresponding to the main system> the second transportation demand corresponding to the 1350 system> the third transportation demand corresponding to the 900 system> the fourth transportation demand corresponding to the 750 system; the first transportation distance corresponding to the main system> the second transportation distance corresponding to the 1350 system> the third transportation distance corresponding to the 900 system, and the third transportation distance corresponding to the 900 system is the same as the fourth transportation distance corresponding to the 750 system. Among them, the main system is equipped with two vehicle groups A1 and A2. In order to meet the first transportation demand and the first transportation distance of the main system, each vehicle group is composed of 4 transport vehicles with a load capacity of 70 tons and a battery power of 525kwh (three main and one backup); the 1350 system itself has 4 transport vehicles with a load capacity of 70 tons and a battery power of 525kwh and 1 transport vehicle with a load capacity of 60 tons and a battery power of 422kwh. Among them, 3 transport vehicles with a load capacity of 70 tons and a battery power of 525kwh are selected as the main vehicles, and 1 transport vehicle with a load capacity of 60 tons and a battery power of 422kwh is selected as the backup vehicle and set as vehicle group B. The remaining 1 transport vehicle with a load capacity of 70 tons and a battery power of 525kwh is allocated to the 750 system; the 900 system is equipped with a vehicle group C, which consists of 4 transport vehicles with a load capacity of 60 tons and a battery power of 422kwh. Vehicle composition (three main and one backup); the 750 system itself has two transport vehicles with a load capacity of 60 tons and a battery capacity of 422kwh and one transport vehicle with a load capacity of 60 tons and a battery capacity of 422kwh. Among them, two transport vehicles with a load capacity of 60 tons and a battery capacity of 422kwh and one transport vehicle with a load capacity of 70 tons and a battery capacity of 525kwh (shared with the 1350 system) are used as the main vehicles, and one transport vehicle with a load capacity of 60 tons and a battery capacity of 422kwh is used as the backup vehicle, which is set as the D vehicle group; it can be understood that based on the actual operating environment, the "three main and one backup" vehicle usage mode can better meet the transportation needs, and allocating the remaining transport vehicles in the 1350 system to the 750 system can not only avoid the idling of the transport vehicles in the 1350 system, but also avoid the problem of system idling caused by too few transport vehicles in the 750 system.The remaining 8 transport vehicles with a load capacity of 60 tons and a battery capacity of 350kwh are divided into two groups E1 and E2. The transport distance of groups E1 and E2 is the shortest. In the embodiment of the present application, the main transport vehicle is the vehicle that has priority in participating in the transportation work, and the spare vehicle is the vehicle used to replace the main transport vehicle that needs to be charged. It can be understood that the present application sets up multiple vehicle groups, and each vehicle group adopts the principle of "three main and one spare", which can not only meet the transportation needs and reduce the number of transport vehicles, but also reduce the pressure of charging and replacement, avoid the problem of centralized charging of transport vehicles and the inability to carry out transportation work normally, and maximize the utilization rate of trams.

[0057] The embodiment of the present application provides a method for dispatching the operation of a tram, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected in a wireless or wired manner, which is not limited in the embodiment of the present application. The method includes steps S101, S102, S103, and S104, wherein:

[0058] Step S101: Acquire the current charging mode of the target vehicle group, and monitor the power of all transport vehicles and non-transport vehicles, or only the transport vehicles, based on the current charging mode until the transport vehicles need to be charged.

[0059] Specifically, the target vehicle group is the vehicle group currently being monitored. Obtaining the current charging mode includes: obtaining the power of all main vehicles, first: if the power of all main vehicles is greater than 50%, the current charging mode is a saturated charging mode; second: when the power of all main vehicles is less than 30%, the current charging mode is an emergency charging mode; third: when the power of all main vehicles is not the first case or the second case, it is determined that the current charging mode is an unsaturated charging mode.

[0060] In the present invention, when the non-transport vehicle is the main vehicle in the saturated charging mode, the power of the transport vehicle and the non-transport vehicle need to be monitored simultaneously; when the non-transport vehicle is the spare vehicle in the saturated charging mode, only the power of the transport vehicle needs to be monitored;

[0061] In the unsaturated charging mode and the emergency charging mode, only the power of the transport vehicle is monitored.

[0062] The monitoring principle corresponding to the saturation charging mode is:

[0063] If the non-transport vehicle is a spare vehicle, monitor whether the power of the transport vehicle reaches the warning value;

[0064] If the non-transport vehicle is the main vehicle, the non-transport vehicle is monitored to see if it is fully charged, and whether the transport vehicle has reached the warning value. In other words, in the saturated charging mode, in addition to ensuring that the transport vehicle can be charged in time when it reaches the warning value, the main vehicle should be placed in the transport state first. When the main vehicle is fully charged, the main vehicle is put on the road regardless of whether the current transport vehicle has reached the warning value.

[0065] In the saturated charging mode, a step charging mode is adopted, and the warning values ​​are set to three, namely 20%, 35% and 50%, and the three values ​​are taken in sequence as warning values.

[0066] The monitoring principle corresponding to the emergency charging mode is: monitor the power of all transport vehicles in real time, and determine the transport vehicle corresponding to the minimum power according to the power of all transport vehicles;

[0067] The monitoring principle corresponding to the unsaturated charging mode is: monitoring whether the transport vehicle reaches the warning value, and the warning value of the unsaturated charging mode and the warning value of the saturated charging mode can be the same value or different values.

[0068] Step S102: Obtain the vehicle status, vehicle attributes and current power of the transport vehicle and the non-transport vehicle.

[0069] Specifically, the current power, vehicle attributes and vehicle status can be obtained from the vehicle information database. The vehicle status is a normal state or a maintenance state, and the vehicle attributes are a main vehicle or a spare vehicle.

[0070] Step S103: Determine the replacement vehicle based on at least one of the vehicle status, vehicle attributes, and current power of the transport vehicle and the non-transport vehicle (in specific implementation, the method of determining the replacement vehicle is different based on different charging modes, which will be described in detail below):

[0071] If a replacement vehicle can be determined, the replacement vehicle is used to replace the transport vehicle that has reached the warning value;

[0072] If a replacement vehicle cannot be identified (this case only involves the saturated charging mode and the transport vehicle reaches the warning value, which will be described in detail below), the power of the transport vehicle will continue to be monitored until a transport vehicle that needs to be charged appears again.

[0073] 1. In saturation mode, the principles for determining replacement vehicles are as follows:

[0074] (1) If a replacement vehicle is required when it is detected that the non-transport vehicle serving as the main vehicle is fully charged, the fully charged main vehicle is used as the replacement vehicle to replace the spare vehicle being transported;

[0075] (2) If the transport vehicle reaches the warning value, the replacement vehicle will be determined according to the following principles:

[0076] ① If the vehicle that reaches the warning value is a spare vehicle, since there is only one spare vehicle, the non-transport vehicle must be the main vehicle at this time: if the non-transport vehicle is fully charged, the replacement vehicle is the non-transport vehicle; if the non-transport vehicle is not fully charged, other vehicles are transferred from the non-target vehicle group as replacement vehicles. If other vehicles cannot be transferred from the non-target vehicle group as replacement vehicles, the fuel vehicle is used as the replacement vehicle, and the non-transport vehicle continues to charge; that is, in the saturated charging mode, once the main vehicle enters the charging state, it should ensure that it is fully charged before replacing the spare vehicle;

[0077] ② If the vehicle that reaches the warning value is the main vehicle, then the non-transport vehicle at this time may be the main vehicle or the spare vehicle. The main vehicle has a higher power requirement than the spare vehicle. Therefore, based on the different properties of the non-transport vehicle, the selection principle of the replacement vehicle is also different:

[0078] ②-1: If the non-transport vehicle is a spare vehicle, the replacement vehicle is determined based on the vehicle status and current power of the non-transport vehicle:

[0079] If the current power of the non-transport vehicle does not reach the power threshold (it may not be fully charged or is under maintenance), other vehicles will be transferred from the non-target vehicle group as replacement vehicles (the non-target vehicle group must be a non-target vehicle group with different transportation tasks). If other vehicles cannot be transferred from the non-target vehicle group as replacement vehicles, the fuel vehicle will be used as the replacement vehicle, and the spare vehicle for the non-transport vehicle will continue to be charged or repaired; the power threshold can be set manually, and it should be ensured that it can at least complete one round trip. In the saturated charging mode, it is set to 20%;

[0080] If the current power of the non-transport vehicle reaches the power threshold, step A is executed: that is, a replacement vehicle is determined based on whether the non-transport vehicle is in a maintenance state and the maintenance time: if the non-transport vehicle is not in a maintenance state, the non-transport vehicle is used as a replacement vehicle on the road; if it is in a maintenance state but the maintenance time is greater than the preset time (it cannot be completed in a short time), other vehicles are transferred from the non-target vehicle group with the lightest transportation task as temporary replacement vehicles. In the present invention, the non-target vehicle group with the lightest transportation task is the E1 and E2 groups; if the non-transport vehicle is in a maintenance state and the maintenance time is less than the preset time (it can be completed after waiting for a while), other vehicles are transferred from the non-target vehicle group with similar transportation tasks as replacement vehicles on the road; if the vehicles in the non-target vehicle group with similar transportation tasks are busy and cannot provide transfer vehicles, fuel vehicles are used for emergency replacement.

[0081] One point that needs to be emphasized is that in the case of a long maintenance time, when retrieving vehicles from other non-target train sets, you can only go to "non-target train sets with similar transportation distances" but not "non-target train sets with the same transportation distances." For example, if the spare vehicle of Group A1 is unable to be used as a replacement vehicle, you can retrieve vehicles from Group B1, but you cannot retrieve vehicles from Group A2, because retrieving vehicles from train sets with the same transportation distance will not actually help complete the corresponding transportation task.

[0082] ②-2: If the non-transport vehicle is the main vehicle, as mentioned above, due to the saturated charging mode, three warning values ​​are set: 20%, 35% and 50%, and these three warning values ​​are used alternately in sequence. Then in the actual monitoring process, the following situation may occur: Assuming that the main vehicle A reaches the warning value of 20%, the main vehicle A is charged, then the warning value in the next monitoring cycle is 50%. Assuming that the main vehicle B reaches the warning value of 50% in the next monitoring cycle, it is possible that the main vehicle A has not yet been charged to 50%; therefore, the non-transport vehicle that is charging during the main vehicle warning is also If the power value of the non-transport vehicle is greater than or equal to the power value of the warning vehicle, the non-transport vehicle will be used as a replacement vehicle, and the transport vehicle that has reached the warning value will be charged. If the power value of the non-transport vehicle is less than the power value of the warning vehicle, the transport vehicle will not be charged at this time, and the power of the transport vehicle will continue to be monitored (this situation corresponds to the above-mentioned "unable to determine the replacement vehicle" situation) until a vehicle in the transport vehicle reaches the warning value of the next cycle (such as 35%).

[0083] In the above situation, when the non-transport vehicle serving as the main vehicle replaces the transport vehicle serving as the main vehicle, the non-transport vehicle only needs to have a power level greater than or equal to that of the transport vehicle and does not need to be fully charged (the main vehicle only needs to be fully charged when replacing the spare vehicle).

[0084] Furthermore, when the main vehicle is warned and the non-transport vehicle is also the main vehicle, before judging the power level of the warning vehicle and the non-transport vehicle, first judge whether the warning vehicle is faulty, that is, judge whether the power consumption value of the warning vehicle is greater than the preset power consumption value. If so, it indicates that there is a sudden change in the power consumption value of the warning vehicle. In order to avoid a continuous sudden drop in the power level of the warning vehicle, step B is no longer executed at this time, and the non-transport vehicle is directly used as a replacement vehicle, and the warning vehicle is charged; if not, execute the above step B, that is, judge the power level of the warning and non-transport vehicles.

[0085] 2. In emergency mode, the principles for determining replacement vehicles are as follows:

[0086] (1) If the transport vehicle with the smallest battery charge is the spare vehicle, the non-transport vehicle is the main vehicle. At this time, the replacement vehicle is determined based on whether the charging time of the non-transport vehicle reaches the preset charging time:

[0087] If the preset charging time is reached, the replacement vehicle is a non-transport vehicle;

[0088] If the preset charging time is not reached, it means that the non-transport vehicle has insufficient power for transportation, and a replacement vehicle is selected from the non-target vehicle group. If no other vehicle can be selected from the non-target vehicle group as a replacement vehicle, a fuel vehicle is used as a replacement vehicle, and the non-transport vehicle continues to charge (and the transport vehicle with the smallest power is also charged);

[0089] The preset charging time is determined according to needs, and in practice should be sufficient for the vehicle to run a full round trip (set to 0.5 hours in the present invention). In this way, each vehicle is charged for 0.5 hours in turn, so that each vehicle can escape from the low-battery state as soon as possible in the best charging method. In addition, through the strategy of charging in turns and taking to the road in turns, the situation where a certain vehicle charges too long and causes other vehicles to run out of power and be unable to go on the road is avoided.

[0090] (2) If the transport vehicle with the lowest power is the main vehicle and the non-transport vehicle is the backup vehicle, the replacement vehicle is determined based on the power and vehicle status of the non-transport vehicle:

[0091] If the current power of the non-transport vehicle does not reach the power threshold (it may not be fully charged or is under maintenance), other vehicles will be transferred from the non-target vehicle group as replacement vehicles (the non-target vehicle group must be a non-target vehicle group with a different transportation task). If other vehicles cannot be transferred from the non-target vehicle group as replacement vehicles, the fuel vehicle will be used as the replacement vehicle, and the spare vehicle for the non-transport vehicle will continue to be charged or repaired; the power threshold can be set manually, and it should be ensured that it can at least complete one round trip. In the emergency charging mode, it is set to 20%;

[0092] If the current power of the non-transport vehicle reaches the power threshold, indicating that the non-transport vehicle is capable of performing the transportation operation, the above step A is executed: determine the replacement vehicle based on whether the non-transport vehicle is under maintenance and the maintenance duration.

[0093] (3) If the transport vehicle with the smallest current power is the main vehicle, and the non-transport vehicle is also the main vehicle, the principle is the same as in part (1) above, and the replacement vehicle is determined based on whether the non-transport vehicle's charging time reaches the preset charging time:

[0094] If the preset charging time is reached, the replacement vehicle is a non-transport vehicle;

[0095] If the preset charging time is not reached, it means that the current power of the non-transport vehicle is insufficient for transportation, and a replacement vehicle is selected from the non-target vehicle group. If no other vehicle can be selected from the non-target vehicle group as a replacement vehicle, a fuel vehicle is used as a replacement vehicle, and the non-transport vehicle continues to charge (and the transport vehicle with the smallest power is also charged).

[0096] 3. In the unsaturated mode, the principles for determining the replacement vehicle are as follows:

[0097] (1) If the vehicle that reaches the warning value is a spare vehicle, since there is only one spare vehicle, the transport vehicle must be the main vehicle: if the non-transport vehicle has completed charging, the replacement vehicle is the non-transport vehicle; if the non-transport vehicle has not completed charging, the replacement vehicle is transferred from the non-target vehicle group. If no other vehicle in the non-target vehicle group can be transferred as a replacement vehicle, the fuel vehicle is used as the replacement vehicle.

[0098] (2) If the vehicle reaching the warning value is the main vehicle, the non-transport vehicle may be the main vehicle or the backup vehicle:

[0099] ①: If the non-transport vehicle is a spare vehicle, the replacement vehicle is determined based on the non-transport vehicle status and current power:

[0100] If the current power of the non-transport vehicle does not reach the power threshold (it may not be fully charged or is under maintenance), other vehicles will be transferred from the non-target vehicle group as replacement vehicles (the non-target vehicle group must be a non-target vehicle group with different transportation tasks). If other vehicles cannot be transferred from the non-target vehicle group as replacement vehicles, the fuel vehicle will be used as the replacement vehicle, and the spare vehicle for the non-transport vehicle will continue to be charged or repaired; the power threshold can be set manually, and it should be ensured that it can at least complete one round trip. In the unsaturated charging mode, it is set to 20%;

[0101] If the current power level of the non-transport vehicle reaches the power threshold, step A is executed: a replacement vehicle is determined based on whether the non-transport vehicle is under maintenance and the maintenance duration.

[0102] ②: If the non-transport vehicle is the main vehicle, the non-transport vehicle will have enough power to perform transportation only when the non-transport vehicle is fully charged. Therefore, it is judged whether the non-transport vehicle has completed charging: if so, the non-transport vehicle is the replacement vehicle; if not, the replacement vehicle is transferred from the non-target vehicle group. If other vehicles in the non-target vehicle group cannot be transferred as replacement vehicles, the fuel vehicle is used as the replacement vehicle.

[0103] In the unsaturated charging mode, the charging time of the non-transport vehicle is determined based on the following principles to further determine whether the non-transport vehicle has completed charging:

[0104] When a vehicle is warned (i.e. before the non-transport vehicle reaches the warning value and is charged), a vehicle with the lowest power is determined from the other vehicles in the target vehicle group, and the charging time is determined based on the power difference between the warning vehicle and the vehicle with the lowest power among the other vehicles in the target vehicle group:

[0105] If the power difference is greater than the high preset value, the warning vehicle needs to be fully charged;

[0106] If the power difference is less than the low preset value, the warning vehicle needs to be charged for 0.5 hours;

[0107] If the power difference is between the low preset value and the high preset value, the warning vehicle needs to be charged for 1 hour.

[0108] Take the high preset value of 15% and the low preset value of 10% as an example: assuming that vehicle A reaches the warning value and needs to be charged as a non-transport vehicle, the power of vehicle A is the first power (usually the lowest power of the target vehicle group). At this time, among vehicles B, C, and D, vehicle B has the lowest power, which is the second power (usually the second lowest power of the target vehicle group); if (second power - first power) is greater than 15%, the preset charging time of vehicle A is full charge; if (second power - first power) is less than 10%, the preset charging time of vehicle A is 0.5 hours (i.e., the first preset value); if (second power - first power) is between 10%-15%, the preset charging time of vehicle A is 1 hour (i.e., the second preset value).

[0109] That is, the principle of setting the charging time is actually to predict that when the early warning vehicle is charging, the early warning vehicle should be charged as much as possible while ensuring that other vehicles in the target vehicle group can support the transportation task.

[0110] Step S104: generating a replacement signal based on the replacement vehicle and the warning vehicle, and generating a charging rotation signal to provide a charging rotation reminder.

[0111] Specifically, the vehicle model of the replacement vehicle and the vehicle model of the warning vehicle can be obtained, and a charging rotation signal can be generated based on the vehicle model of the replacement vehicle and the vehicle model of the warning vehicle. The charging rotation signal can be in text form or voice form, and the charging rotation signal is sent to the replacement vehicle side device and the warning vehicle side device to remind the driver to charge in time.

[0112] It is not difficult to understand that the premise of the above embodiment of the present invention is that the main vehicle is in a stable state and does not need to be repaired. Therefore, the main vehicle can be put on the road as long as the power meets the requirements, without considering whether the main vehicle is in a state of repair or maintenance. However, if the main vehicle needs to be repaired or maintained in practice, the main vehicle and the spare vehicle need to be replaced. The replacement principle is as follows:

[0113] 1. If the main vehicle in the A1 or A2 train set of the main system with the longest transportation distance and the largest load capacity needs to be repaired and maintained and cannot participate in production, the spare vehicle of A1 or A2 will be temporarily upgraded to the main vehicle. If the spare vehicle in this group is missing, one of the four vehicles in the B train set of the 1350 system, which is also a 70-ton vehicle, will be used. The spare vehicle of the 1350 system will be used as the main vehicle in an emergency. A vehicle from the E1 and E2 train sets of the non-production system will be used temporarily as the spare vehicle of the 1350 system B group. If there is no equipment available, the fuel equipment will be used as the spare vehicle for emergency replacement.

[0114] The reason for such a large-scale scheduling here is that the main system has the highest production output requirement, which can only be met by using 6 70-ton models to participate in production at the same time, so it is necessary to give priority to ensuring that the 70-ton model is used in the main system.

[0115] 2. If the main vehicle of Group B of the 1350 system has the above problems and cannot participate in production, a vehicle from the E1 and E2 groups of the non-production system will be directly deployed to temporarily serve as the spare vehicle of Group B of the 1350 system. If there is no equipment available, the fuel equipment will be used urgently as the spare vehicle for emergency replacement.

[0116] 3. If the main vehicles of Group C and Group D of the 900 system and 750 system have the above problems and cannot participate in production, a vehicle of the E1 and E2 groups of the non-production system will be directly deployed to temporarily serve as a spare vehicle for Group B of the 1350 system. If there is no equipment available, the fuel equipment will be used urgently as a spare vehicle for emergency replacement.

[0117] 4. If the main vehicle or spare vehicle of the E1 or E2 group participating in non-production system operations is under maintenance, since the vehicles participating in the non-production system generally have shorter transportation distances and lower SOC consumption values, only emergency deployment is required within the E1 and E2 groups at this time, which generally will not have much impact on the overall production. In extreme cases where there is no vehicle to deploy, a fuel vehicle will be used to replace it.

[0118] Furthermore, in the embodiment of the present application, it also includes:

[0119] Obtain charging signals from the non-transport vehicle and the charging pile, and determine abnormal charging information of the non-transport vehicle based on the charging signals;

[0120] If the abnormal charging information indicates that an abnormality exists, an abnormal charging signal is generated based on the non-transport vehicle to alert the technician.

[0121] Specifically, a charging monitor is provided on the charging pile to monitor whether there is charging abnormality in the non-transport vehicle. In the embodiment of the present application, when the non-transport vehicle jumps the gun, it indicates that there is charging abnormality in the non-transport vehicle. The charging monitor is uploaded to the electronic device in real time. In the embodiment of the present application, the charging signal can be a charging current signal; when the electronic device determines that there is charging abnormality in the non-transport vehicle, an abnormal charging signal is generated and sent to the dispatching management personnel side device to remind the dispatching management personnel to check the non-transport vehicles with charging abnormalities in time to avoid the non-transport vehicles being unable to participate in subsequent transportation.

[0122] Based on the above embodiment, the charging status of non-transport vehicles is monitored in real time, and charging abnormalities are promptly processed, thereby effectively improving the charging efficiency of non-transport vehicles and avoiding the inability of non-transport vehicles to participate in the next transportation due to untimely charging, so as to better meet transportation needs.

[0123] The above are only some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
