Referring to FIG. 3 , it illustrates a flow chart of an embodiment of the transfer inquiry method of the mobile communication terminal in FIG. 1 . As shown in the figure, the following steps are included:

S200, obtaining the start station, the end station and the maximum number of transfers and pushing them into stacks. That is, obtain the starting station, the terminal station and the maximum number of transfers allowed by the user; and push the parameters of the starting station, the terminal station and the maximum number of transfers allowed;

S201. Find all ride schemes satisfying the conditions from the current station. The current station refers to the current starting station, that is, the current station as the starting station. When this step is performed for the first time, the current station is the starting station in step S200. When starting from the following step S209 After executing this step, the current site is the current site determined in step S209;

S202, judging whether the current start station is the end station, if so, then execute S210, otherwise execute step S203;

S203, judging whether transfer is still possible, if yes, execute step S204, otherwise execute step S211. Judging whether it is still possible to transfer is realized by judging whether the current number of transfers has reached the maximum number of transfers set in step S200; because each transfer will add up the number of transfers, this judgment step is set to prevent exceeding the maximum number of transfers ;

S204. Take a route from the bus data of the current station, and obtain the next station on the route. For example: the current starting station is B234, and the lines including the current station can be obtained from the bus data as L1, L2, L3, L4, and L5. At this time, select a line from L1~L5 and get it from the local bus data The next station of the line; wherein, the next station can be the next station adjacent to the current starting station, or can also select the next station according to the preset step size;

S205, judging whether the next site of the selected line has been successfully obtained in step S204, if so, then perform step S206, otherwise re-execute step S204 to find the next line or next site;

S206, judging whether the line and station selected in step S204 pass through, if yes, execute step S207, otherwise execute step S204. That is, it is judged whether the line has been passed through the station before. For example, the line currently being calculated up to this step is: take L1 at the starting station, transfer to L4 at the B398 station, get off at the B230 station, and select through step S204 L2 and next station B987, because do not take the part that line L2 transfers at station B987 in the part that has been calculated, thereby this step is identified as not passing through, thereby performing step S207; For the above example, the situation of not passing through It also includes taking the L2 but not changing at the station B987, or not taking the L2 but changing at the station B987; therefore, there is only one case that is considered to be passing, that is, taking the L2 and transferring at the station B987 Transferred;

S207, judging whether to transfer, if yes, execute step S208, otherwise execute step S209. It judges according to whether the line selected in step S204 is the same line as the previous line. If it is the same line, there is no transfer relationship, so this step is judged as no transfer; if it is not the same line, there is a transfer relationship. Therefore, this step is judged as transfer. The purpose of this step is to determine whether to accumulate the number of transfers in step S208;

S208, record the line, and accumulate transfer times. That is, after successfully obtaining the next station, then record the line and the next station, and simultaneously add 1 to the number of transfers (because it is not the same line as judged through step S207);

S209, taking the obtained station as the current station, and pushing all the passing lines and stations and the parameters of the current number of transfers onto the stack. That is, step S201 is executed again with the next station obtained in step S204 as the new current station to continue to complete the complete line calculation, and at the same time, each parameter is pushed onto the stack for storage. After this step ends, execute step S201;

S210, record the result. That is, when the current station is the terminal station, it means that the transfer plan has been calculated, and the entire transfer plan is stored at this time; and at the same time, the cost of the plan is calculated; after this step is completed, step S213 is executed;

For example, the resulting complete scheme looks like this:

Take L1 at the starting station, transfer to L11 at station B555, transfer to L21 at station B666, transfer to L31 at station B777, and finally arrive at the terminal station; at this time, the billing method of each line is obtained from the local bus database, according to The billing method calculates the expenses. For example, the billing method of L1 is a single ticket system of 1 yuan, L11 is also a single ticket system of 2 yuan, L21 is billed by sections, and L31 is a single ticket system of 1 yuan, and the cost of the section that the user passes through on the L21 line is calculated is 2 yuan, and the expense at this time is 1+2+2+1=6 yuan;

S211, searching for all direct lines between the current station and the terminal station. It should be noted that the direct line mentioned here is not a direct line from the original starting station (the starting station set in step S200) to the terminal station, but a direct line from the current station to the terminal station .

For example, the starting station set in step S200 is B1234, the terminal station B4321, and the current station is B888, assuming that there is a line L007 in the bus data of the current station, which includes station B888 and terminal station B4321, then it is considered that there is a so-called direct line, otherwise none;

S212. Record all directly reachable results. That is, record the direct line information obtained in the previous step (including complete line information);

S213. Pop a set of parameters from the stack. That is, pop the information that was previously pushed into the stack;

S214, judging whether the data popped from the stack is empty, if yes, execute step S216, otherwise execute step S215. That is, when the pop-up content is empty, it means that all possible lines have been traversed at this time, and the process can be ended; if it is not empty, it means that the traverse has not been completed, and then continue to execute step S215;

S215, setting the pop-up site as the current site. That is, the current site in the data ejected in step S213 is used as the starting station so as to re-execute step S201 to traverse;

In another embodiment of the transfer query method of the present invention, on the basis of the embodiment shown in Figure 3, in step S204, the unpassed line and its next station are directly taken, so the judgment in step S206 can be omitted step.

In yet another embodiment of the transfer query method of the present invention, on the basis of the embodiment shown in Figure 3, step S203 can be omitted, so that all lines that can arrive at the terminal station from the starting station have been traversed, and in steps S214 and During S216, the filtering of transfer times of all plans obtained is added, and the plans exceeding the maximum transfer times are discarded.

It should be noted that the public transport data mentioned in the present invention refers to the combination of all possible public transport modes. For example, any combination between bus, tram, high-speed train, subway or light rail.

The above disclosure is only a preferred embodiment of the present invention, which certainly cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
