In the embodiment of the application, the ROM101 is connected with the target application module 102 in an interprocess communication manner, the ROM101 is physically connected with the first hardware device 200, a communication channel between the target application module 102 and the first hardware device 200 is established through the ROM101, and the information communication between the target application module 102 and the first hardware device 200 is realized based on the communication channel established by the ROM101, that is, the linkage information communication among the target application module 102, the ROM101 and the first hardware device 200 is realized, so that a high-quality travel service can be provided for a driver or a passenger. Through the connection mode, the connection pairing time between the electronic device 100 and the hardware device is saved, the connection stability is good, the communication safety is high, and the communication efficiency is improved.

The following describes a linkage communication process in a network car booking service scenario based on the communication connection among the ROM101, the target application module 102, and the first hardware device 200:

first, in the electronic device 100 provided in this embodiment of the application, the first hardware device 200 may report first data information of the first hardware device 200, for example, state information of the first hardware device 200, to the target application module 102 through the ROM 101.

The ROM101 is specifically configured to receive a first combined voltage signal sent by the first hardware device 200, convert the first combined voltage signal into first data information corresponding to the first hardware device 200, and send the first data information to the target application module 102;

the target application module 102 is specifically configured to receive the first data information, generate response information of the first data information, and send the response information to the ROM 101;

the ROM101 is further configured to receive the response information and send the response information to the first hardware device 200 or the second hardware device 200.

In the embodiment of the present application, the first hardware device 200 sends a first combined voltage signal representing the first data information to the ROM101, and the ROM101 receives the first combined voltage signal and converts the first combined voltage signal into the first data information. Here, the first combined voltage signal is converted in the following manner: the ROM101 writes the first combined voltage signal into a target file corresponding to the first combined voltage signal, and the target application module 102 obtains first data information by reading the target file. After acquiring the first data information, the target application module 102 may generate response information of the first data information, and send the response information to the first hardware device 200 through the ROM 101. The target application module 102 may also simply display the first data information.

Secondly, in the electronic device 100 provided in this embodiment of the application, the target application module 102 may further set the device state of the first hardware device 200 through the ROM101, or the target application module 102 sends the second data information to the first hardware device 200 through the ROM 101: wherein,

the target application module 102 is specifically configured to send a state setting instruction or second data information to the ROM 101;

the ROM101 is specifically configured to receive the state setting instruction or the second data information, convert the state setting instruction or the second data information into a second combined voltage signal, and send the second combined voltage signal to the first hardware device 200; wherein the second combined voltage signal is used to set a device state of the first hardware device 200 or used for the first hardware device 200 to process the second data information.

In this embodiment, the target application module 102 sends a state setting instruction to the ROM101, after receiving the state setting instruction, the ROM101 converts the state setting instruction into a second combined voltage signal, for example, converts the state setting instruction corresponding to the state in the trip into the second combined voltage signal 1000000011, and then, the ROM101 sends the second combined voltage signal to the first hardware device 200 (for example, a meter). Wherein the second combined voltage signal is used to set the device state of the first hardware device 200. The first hardware device 200 sets the current state after receiving the second combined voltage signal, for example, sets the current state to the in-flight state.

Alternatively, the target application module 102 sends the ROM101 second data information (e.g., transaction amount after completion of the service order), and after receiving the second data information, the ROM101 converts the second data information into a second combined voltage signal, e.g., converts the transaction amount 50 into the second combined voltage signal 1100000011, and then the ROM101 sends the second combined voltage signal to the first hardware device 200 (e.g., the meter). After receiving the second combined voltage signal, the first hardware device 200 processes the second combined voltage signal, for example, displays a transaction amount 50 corresponding to the second combined voltage signal.

For example, the target application module 102 receives a service order, when a driver receives a passenger and the passenger confirms to get on the vehicle, the target application module 102 sets the state of the meter to be a travel state through the ROM101, and the meter reports current state information to the target application module 102 through the ROM101 in real time in the process of executing order service by the driver; after the order is finished, the target application module 102 sends the travel information to the printer through the ROM101, and the printer prints an invoice including the travel information; meanwhile, the target application module 102 sets the state of the meter to the trip end state through the ROM 101.

Considering that some hardware devices (for example, the second hardware device 300 described below) have a wireless communication module but do not have a physical interface, and accordingly, the ROM101 cannot be physically connected to the second hardware device 300, in this embodiment of the present application, the ROM101 is communicatively connected to the second hardware device 300 in a wireless communication manner, and then the ROM101 establishes a communication channel between the target application module 102 and the second hardware device 300, and the communication channel established based on the ROM101 realizes information communication between the target application module 102 and the second hardware device 300. Finally, linkage communication among the target application module 102, the ROM101, the first hardware device 200 and the second hardware device 300 can be realized.

Further, as shown in fig. 2, in the electronic device 100 provided in the embodiment of the present application, the electronic device 100 further includes a wireless communication module 103, and the ROM101 is connected to the second hardware device 300 through the wireless communication module 103 in a wireless communication manner; the second hardware device 300 performs information transmission with the ROM101 in a wireless communication mode;

the ROM101 is further used for realizing information transmission between the target application module 102 and the second hardware device 300 through the wireless communication mode and the interprocess communication mode.

In the embodiment of the present application, the second hardware device 300 may also be a vehicle-mounted device, such as a point of sale (pos) machine fixed in a vehicle, and the pos machine is used for cashless settlement of a service order.

In this embodiment of the application, the ROM101 is connected to the second hardware device 300 through a Wireless communication module 103 in a Wireless communication manner, and the Wireless communication module 103 may be a bluetooth module or a Wireless local area network (WIFI) module. Here, the Bluetooth module may be a ble (Bluetooth Low energy) Low energy Bluetooth module, and may also be a standard Bluetooth module.

The ROM101 is further in communication connection with the target application module 102, so that a communication channel between the target application module 102 and the second hardware device 300 can be established, and correspondingly, the ROM101 performs information transmission with the second hardware device 300 in a wireless communication manner, and performs information transmission with the target application module 102 in an inter-process communication manner, so as to achieve information transmission between the target application module 102 and the second hardware device 300.

As shown in fig. 3, for example, the second hardware device 300 is communicatively connected to the ROM101 through a BLE module or a Bluetooth module.

In this embodiment of the application, the target application module 102 is configured to be in communication connection with each of the first hardware device 200 and the second hardware device 300 in the vehicle, and perform linkage communication with each of the first hardware device 200 and the second hardware device 300 in the vehicle, so as to realize linkage of travel services, and facilitate improvement of services for a driver and travel of passengers.

For example, the target application module 102 receives a service order, and when the driver receives a passenger and the passenger confirms getting on the vehicle, the target application module 102 sets the state of the meter to be in-trip state through the ROM 101; in the process of executing order service by a driver, the taximeter and the vehicle lamp report the current state information to the target application module 102 in real time through the ROM 101; after the order is finished, the target application module 102 sends the transaction amount of the order to the pos machine through the ROM101, and after the pos machine finishes the transaction, the transaction result is returned to the target application module 102 through the ROM 101.
