Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The method for multipath communication between the parking lot equipment and the cloud end in the embodiment is shown in fig. 1, and includes the parking lot equipment 1 and the cloud end server 2, where the parking lot equipment 1 supports parallel connection of multiple mutually independent networks, and as shown in fig. 2, the multiple networks of the parking lot equipment 1 are connected in parallel with the cloud end server 2, and as shown in fig. 3, the method includes the following steps:
a transmission strategy setting step, in which the cloud server 2 presets transmission strategies of all parallel connected networks and sends the transmission strategies to the parking lot equipment 1, wherein the transmission strategies comprise data types required to be transmitted;
a data transmission step, wherein when the parking lot equipment 1 reports data to the cloud server 2, the parking lot equipment 1 firstly distributes corresponding data to corresponding networks according to a transmission strategy corresponding to each network, and then all the networks connected in parallel transmit the data to the cloud server 2 at the same time;
when the cloud server 2 issues data to the parking lot device 1, the cloud server 2 firstly distributes corresponding data to corresponding networks according to the transmission strategy corresponding to each network, and then all the networks connected in parallel transmit data to the parking lot device 1 at the same time;
a data selection step, wherein when the parking lot equipment 1 reports data to the cloud server 2, the cloud server 2 selects a network which receives the data firstly as a receiving and sending network, and receives the data of the receiving and sending network for processing;
and when the cloud server 2 issues data to the parking lot equipment 1, the parking lot equipment 1 selects a network which receives the data firstly as a receiving and sending network, and receives the data of the receiving and sending network for processing.
The parking lot equipment and cloud end multi-path communication method is based on communication connection of the parking lot equipment 1 and the cloud end server 2, multiple mutually independent networks are connected in parallel between the parking lot equipment 1 and the cloud end server 2, data are transmitted on all the networks connected in parallel at the same time, and therefore when network fluctuation or disconnection occurs in the multiple networks, other networks still transmit the data, and normal communication connection of the parking lot equipment 1 and the cloud end server 2 is guaranteed. The multiple networks of the parking lot equipment 1 are connected with the cloud server 2 in parallel through corresponding communication protocols; the communication protocol includes Universal Mobile Telecommunications System (UMTS) protocol, global system for mobile communications (GSM) protocol, code division multiple access protocol, TCP/IP protocol, IPX/SPX protocol, NetBEUI protocol, and the like.
When the parking lot equipment 1 reports data to the cloud server 2, the cloud server 2 automatically selects a network which receives the data firstly as a receiving and sending network, extracts the data of the receiving and sending network for processing, and does not process the data of other networks; when the cloud server 2 issues data to the parking lot device 1, the parking lot device 1 automatically selects a network which receives the data first as a receiving and sending network, extracts the data of the receiving and sending network for processing, and does not process the data of other networks; "the data received first" means that the data to be transmitted by the network has been completely received and the completion time is shortest; the "data processing" refers to parking transaction processing for determining the parking time of the vehicle and calculating the parking fee from the received data. Therefore, the inconsistency of the local data of the vehicles entering and exiting the parking lot and the cloud data caused by the network problem caused by network fluctuation is prevented, and financial confusion and even financial disputes caused by the inconsistency are avoided.
The transmission strategy setting step configures different transmission strategies according to the characteristics of different networks, the types of data to be transmitted comprise unlimited data types, only character data and only non-picture data, namely the types of the network transmission data connected in parallel are different, so as to ensure that the data transmission of each network is stable and maintain a higher transmission speed, and effectively reduce the operation cost of the parking lot. For example, as shown in fig. 4, when the parking lot device 1 and the cloud server 2 are connected in parallel by the network N, the network N +1 to the network N + M, the transmission policy of the network N is set to X, the transmission policy of the network N +1 is set to X +1, and the transmission policy of the network N + M is set to X + Y.
For another example, if the parking lot device 1 supports a 4G network and a wired network, and both networks are connected in parallel for transmission, the transmission policy of the 4G network is set to transmit only non-picture data, and the transmission policy of the wired network is set to not limit the data types, when the parking lot device 1 reports data to the cloud server 2, the parking lot device 1 distributes all types of data to the wired network, and simultaneously distributes the non-picture data to the 4G network, and then the 4G network and the wired network transmit data to the cloud server 2 at the same time;
if network fluctuation or disconnection occurs in the wired network in the transmission process, the 4G network still transmits data to the cloud server 2, so that the cloud server 2 firstly receives non-picture data transmitted by the 4G network, the cloud server 2 only processes the non-picture data, and even if the wired network recovers transmission later, the cloud server 2 cannot process the received wired network data;
however, if the wired network resumes transmission, the cloud server 2 still does not receive the data of the 4G network, and at this time, if the transmission speed of the wired network exceeds the transmission speed of the 4G network, so that the cloud server 2 receives all the data transmitted by the wired network first, the cloud server 2 processes all types of data, and the subsequently received 4G network data is not processed.
Preferably, as shown in fig. 5, in the priority setting step, the cloud server 2 sets the priority of each of the networks connected in parallel in advance, forms a network priority distribution table, and sends the network priority distribution table to the parking lot device 1; and a network selection step, when a plurality of networks which receive data firstly exist, selecting the network with the highest priority from the plurality of networks which receive data firstly as a transceiving network according to the network priority distribution table.
The priority of the network is determined by factors such as the error rate of the network, the transmission strategy and the like, and the lower the error rate is, the more types of the transmission data are, the higher the priority is. The network priority distribution table is set, so that when a plurality of networks receive data firstly, which network is selected as a receiving-transmitting network can be selected by comparing the priority levels, thereby ensuring that the processed data tend to have low error rate and more types, and avoiding the influence on subsequent data processing caused by randomly selecting the network.
Preferably, as shown in fig. 6, the system further includes a management terminal 3, and the management terminal 3 is connected to the cloud server 2 through a communication network, as shown in fig. 7, the method further includes the following steps:
a transceiving counting step, in which the cloud server 2 counts the times of the networks becoming transceiving networks in a preset period to form a transceiving network counting table, screens out the networks with the times of the networks becoming transceiving networks exceeding a transceiving threshold from the transceiving network counting table to form a transceiving frequent network list, and then sends the transceiving network counting table and the transceiving frequent network list to the management terminal 3;
and a parameter adjusting step, in which the management terminal 3 adjusts the transmission strategy and priority of each network according to the transceiving network statistical table and the transceiving frequent network list.
By counting the times that each network becomes a transceiving network, the networks with frequent transceiving are screened out to form a transceiving frequent network list, and the networks in the transceiving frequent network list are indicated to be networks with high transmission stability and difficult network fluctuation or disconnection, so that a manager can improve the priority of the networks and increase the types of data which can be transmitted by the networks at the management terminal 3, and data support is provided for the manager to adjust the transmission strategy and the priority of each network, and the adjustment is more scientific and reasonable.
Preferably, as shown in fig. 8, the method further comprises the following steps:
a transmission counting step, wherein when the parking lot equipment 1 reports data to the cloud server 2, the cloud server 2 counts networks with data transmission time exceeding a transmission threshold value and defines the networks as transmission delay networks to form a transmission delay network list;
and a maintenance reminding step, wherein the cloud server 2 counts all transmission delay network lists in the preset period, screens out networks with the transmission delay network times exceeding a delay threshold value to form a to-be-maintained network list, and sends the to-be-maintained network list to the management terminal 3.
The network with the transmission delay time exceeding the transmission threshold is screened out through counting the networks with the data transmission time exceeding the transmission threshold, a network list to be maintained is formed, and the network in the network list to be maintained is the network with poor transmission stability and frequent network fluctuation or disconnection, so that a manager is reminded that the networks need to be maintained and optimized, the manager does not need to check by himself, and convenience is brought to network management.
