[0021] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0022] See also Figure 1 , an embodiment of the present invention provides a parking lot call service method, which includes the following steps:

[0023] Step 101: receiving a call service request triggered by a driver at a parking lot gate.

[0024] When drivers drive their vehicles in and out of parking lots, they sometimes encounter problems that prevent them from entering or exiting the parking lot normally. For example, some drivers have questions about parking fees when leaving the parking lot. In this case, they need to contact the parking lot operator for a solution. Some drivers have already paid when leaving the parking lot, but the gate does not open. In this case, they need to contact the parking lot operator for help. Some drivers enter the parking lot but their license plate is not recognized, so the gate cannot open normally. In this case, they need to contact the parking lot operator for help. Therefore, parking lot operators usually set up a call terminal at the gate. When drivers encounter a problem, they trigger the call terminal to establish a call link with the problem solver.

[0025] Specifically, when the driver triggers the call terminal, a call service request is generated. This service request carries the parking lot identification and is sent to the cloud service dispatch console. The call terminal can be in the form of a QR code. The driver generates a call service request by scanning the QR code with a mobile phone. This form facilitates the driver's operation. In other embodiments, a call service request can also be generated by triggering a button, which is not limited in this embodiment. Some parking lots may have multiple entrances and exits. In order to better identify each entrance and exit, the parking lot identification can also identify each entrance and exit.

[0026] Step 102 : In response to the call service request, determine the service data of the current parking lot.

[0027] Upon receiving a call service request, the current service data corresponding to the parking lot is determined based on the parking lot identification included in the request. The current service data may vary for different parking lots. For some parking lots, the current service data may be the current call time. For others, the current service data may be the total number of current calls. For still others, the current service data is the parking lot identification. The content of the current service data is determined based on the actual operation of the parking lot and is not limited in this embodiment.

[0028] Step 103 : According to the current service data, one of the cloud agent terminal mode, the local agent terminal mode, and the local on-site personnel mode is selected as the operator mode.

[0029] There are generally three types of problem solvers in step 101: cloud agents, local agents, and local on-site personnel. When the problem solver is a cloud agent (or purely remote agent mode), this mode is called the cloud agent terminal mode. When the problem solver is a local agent, this mode is called the local agent terminal mode. When the problem solver is a local on-site personnel, this mode is called the local on-site personnel mode (or traditional call mode). Based on the current service data, one of the three modes is selected as the operator mode, that is, one of the cloud agent, local agent, or local on-site personnel is selected as the operator.

[0030] Specifically, when the current service data is the total number of current calls, the relationship between the total number of current calls and a preset call threshold is determined. If the determination result is: the current total number of calls is less than the call threshold, the original operator mode is maintained. That is, if the original operator mode is cloud-based agent terminal mode, the current operator mode remains cloud-based agent terminal mode. If the determination result is: the current total number of calls is greater than or equal to the call threshold, a new operator mode is determined. The new operator mode is different from the original operator mode. That is, if the original operator mode is cloud-based agent terminal mode, the current operator mode is local agent terminal mode or local on-site operator mode; if the original operator mode is local agent terminal mode, the current operator mode is cloud-based agent terminal mode or local on-site operator mode. Based on this, the parking lot will have two modes: the original operator mode and the new operator mode. By adopting two modes, dispatched by the cloud service dispatch desk, drivers can receive a quick response regardless of the subsequent service provider. For example, using the original call center mode as the primary service method and the new call center mode as a backup during busy periods is suitable for parking lots with insufficient staff or high traffic volumes during holidays, resulting in frequent calls. When a parking lot has two modes: local agent terminal mode and cloud agent terminal mode, it indicates that the parking lot has established not only a local call center but also a remote service center to ensure that all service calls receive a timely response.

[0031] The current service data also includes the current call time. Accordingly, the execution process of this step is as follows: determining whether the current call time is within a preset adjustment time period; if the time determination result is that the current call time is within the non-adjustment time period, determining to maintain the original operator mode; if the time determination result is that the current call time is within the adjustment time period, determining the relationship between the total number of current calls and the call threshold; if the call determination result is that the total number of current calls is less than the call threshold, determining to maintain the original operator mode; if the call determination result is that the total number of current calls is greater than or equal to the call threshold, determining a new operator mode.

[0032] Step 104: In the operator mode, the operator establishes a call link with the driver.

[0033] When the operator mode is the local on-site personnel mode, the driver triggers the call terminal. The cloud service dispatch console has pre-stored the phone number of the local on-site personnel, so a call link is established between the local on-site personnel and the driver, and the local on-site personnel provides service to the driver.

[0034] When the operator mode is purely local agent mode, the driver triggers the call terminal. The cloud service dispatcher establishes a call link between the parking lot's local duty terminal (or local agent) and the driver, and the local duty agent handles the driver's call. As the call service is connected, the cloud service dispatcher pushes information about the driver's lane to the agent's screen, allowing them to keep abreast of the situation. The local duty terminal is typically the duty center of the parking lot. Lane information includes the lane name, vehicle license plate, gate image, and may also include a video corresponding to the lane.

[0035] When the operator mode is set to pure remote agent mode, the driver triggers a call to the terminal. The cloud service dispatcher arranges for the parking lot's designated remote duty terminal to establish a call connection with the driver, and the remote duty agent handles the call. As the call is connected, the cloud service dispatcher simultaneously pushes the driver's lane information to the remote agent's screen, allowing them to keep abreast of the situation. The local duty terminal is typically the parking lot's duty center. Lane information includes lane name, vehicle license plate, gate image, and may also include a video corresponding to the lane.

[0036] To better utilize resources and improve resource utilization, the service request also carries a service mode identifier, namely, a parking lot identity identifier and a service mode identifier. Service mode identifiers include single mode and hybrid mode. Single mode can be cloud agent terminal mode, local agent terminal mode, or local on-site staff mode. Hybrid mode includes at least cloud agent terminal mode and local agent terminal mode, for example, cloud agent terminal mode, local agent terminal mode, and local on-site staff mode.

[0037] Accordingly, in response to the call service request, the current service data of the parking lot is determined, including:

[0038] In response to the call service request, the type of service mode identification is determined. If the judgment result of the service mode identification type is single mode, the single mode is selected as the operator mode, and then step 104 is continued; if the judgment result of the service mode identification type is mixed mode, the current service data of the parking lot is determined, and then steps 103-104 are continued.

[0039] For example, some parking lots, based on their operational needs, may preset a service mode identifier of single mode and a type of cloud agent terminal mode. Upon receiving a call service request, the parking lot determines that the service mode identifier type is single mode and the cloud agent terminal mode is used as the operator mode, and then executes step 104. Other parking lots, based on their operational needs, may preset a service mode identifier of mixed mode. Upon receiving a call service request, the parking lot determines that the service mode identifier type is mixed mode and then executes steps 103-104. Other parking lots, based on their operational needs, may sometimes be set to single mode and sometimes to mixed mode, and this embodiment does not limit this.

[0040] By receiving the call service request triggered by the driver at the parking lot gate, responding to the call service request, determining the current service data of the parking lot, and according to the current service data, selecting one of the cloud agent terminal mode, local agent terminal mode and local on-site personnel mode as the operator mode, in the operator mode, the operator establishes a call link with the driver, thereby conveniently providing the driver with various call link methods, completing traditional calls, local agent services or remote agent services, greatly reducing the operating costs of the parking lot, and improving the operating efficiency of the parking lot and the response efficiency of the service.

[0041] See also Figure 2 The present invention provides a parking lot call service device for executing the parking lot call service method of the above embodiment. The device includes a request receiving module 201, a data determining module 202, a mode determining module 203, and a call establishing module 204.

The data determination module 202 is used to determine the parking lot's current service data in response to the call service request. The mode determination module 203 is used to select one of the following modes: cloud agent terminal mode, local agent terminal mode, or local on-site personnel mode, based on the current service data, as the operator mode.

[0043] Optionally, the mode determination module 203 includes a mode maintaining unit and a mode updating unit.
