It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a block diagram illustrating the structure of an information acquisition system according to an exemplary embodiment. Referring to fig. 1, the system may include: the system comprises a server 1, at least one vehicle machine 2 and at least one client 3. In the present disclosure, the server 1 is in communication connection with each car machine 2 and each client 3, and the server 1 and each car machine 2 and each client 3 may communicate via a 2G network, a 3G network, a 4G network, bluetooth, WIFI, etc., for example, to complete data transmission. The client 3 may be configured to receive instruction information and vehicle machine identification information input by a user, and send the instruction information and the vehicle machine identification information to the server 1; the server 1 may be configured to receive the instruction information and the car machine identification information, and send the instruction information to the car machine 2 corresponding to the car machine identification information; the car machine 2 may be configured to obtain car machine state information corresponding to the instruction information after receiving the instruction information, and feed back the car machine state information to the client 3 through the server 1. The client 3 may be, for example, a smart phone, a tablet computer, a personal computer, or the like, and is not particularly limited in this disclosure.
Specifically, the server 1 may implement, through steps 201 to 204 shown in fig. 2, obtaining the vehicle-machine state information of the corresponding vehicle machine.
In step 201, instruction information and car machine identification information sent by a client are received.
In this disclosure, the car machine identification information may be an Integrated Circuit Card Identification (ICCID), a car machine number, or the like. The instruction information may be an instruction for acquiring network card information of the vehicle machine, may also be an instruction for acquiring a current running state of the vehicle machine, and may also be an instruction for acquiring corresponding cache data on the vehicle machine, which is not specifically limited in this disclosure.
When a user needs to know the vehicle-machine state information of any vehicle machine, corresponding instruction information and vehicle-machine identification information can be input into the client; after receiving the instruction information and the vehicle machine identification information, the client can send the instruction information and the vehicle machine identification information to the server; and the server receives the instruction information and the vehicle machine identification information.
In step 202, the instruction information is sent to the car machine corresponding to the car machine identification information through a publish-subscribe protocol.
In the present disclosure, the publish-subscribe protocol may be a Message Queue Telemetry Transport (MQTT), a card (Kafka) protocol, or the like. Furthermore, the server may pre-store a corresponding relationship between the car machine identification information and the car machine network address, for example, the server may store the corresponding relationship in a table form. In this way, after the server receives the vehicle machine identification information and the instruction information sent by any client, the network address of the vehicle machine corresponding to the received vehicle machine identification can be determined by searching the corresponding relationship between the pre-stored vehicle machine identification information and the vehicle machine network address; then, the server may send the instruction information to the network address through a publish-subscribe protocol, that is, to the car machine corresponding to the car machine identifier, and the car machine receives the instruction information through the publish-subscribe protocol.
After the vehicle machine corresponding to the vehicle machine identifier receives the instruction information, the vehicle machine state information corresponding to the instruction information can be acquired through a java reflection mechanism according to the instruction information. Specifically, after receiving the instruction information, the car machine corresponding to the car machine identifier may parse the instruction information; then, according to the analyzed instruction information, acquiring the running environment of the current JVM through a java reflection mechanism (runtime. getruntime () function), and then transmitting the analyzed instruction information to an exc () method for execution, wherein the return value of the exc () method is the vehicle machine state information; then, the car machine sends the car machine state information to a server, for example, the car machine may send its own car machine state information to the server through hypertext transfer Protocol (HTTP); the server receives the car machine state information (step 203).
In step 203, the car machine state information sent by the car machine is received.
In step 204, the vehicle machine state information is sent to the client.
In this disclosure, after receiving the car machine state information sent by the car machine, the server may send the car machine state information to the client, and the client receives the car machine state information. Therefore, the user can obtain the vehicle-machine state information of the corresponding vehicle machine through the client.
In the technical scheme, the client sends the instruction information and the vehicle machine identification information to the server; then, the server sends the instruction information to the vehicle machine corresponding to the vehicle machine identification information through a publish-subscribe protocol; the vehicle machine receives the instruction information through a publish-subscribe protocol, acquires vehicle machine state information corresponding to the instruction information through a java reflection mechanism, and sends the vehicle machine state information to the server; and the server receives the vehicle machine state information and feeds the vehicle machine state information back to the client. Therefore, the user can obtain the instant state information of the corresponding vehicle machine at any time and any place through the client, and the method is convenient and fast. And the acquired instant state information is more comprehensive, a more powerful basis is provided for vehicle machine fault diagnosis, and a user can conveniently and accurately position faults.
Fig. 3 is a flowchart illustrating an information acquisition method according to another exemplary embodiment, wherein the method may be applied to a server, for example, the server 1 illustrated in fig. 1. As shown in fig. 3, the method may further include the following steps 205 to 207.
In step 205, after the instruction information and the in-vehicle machine identification information are received, a random code is generated.
In step 206, the random code is sent to the car machine, and the random code and the instruction information are stored in an associated manner.
In this disclosure, in order to facilitate a subsequent user to continuously obtain the vehicle device state information in a short time and obtain the vehicle device state information in a historical time period, the server may locally store the vehicle device state information after obtaining the vehicle device state information. However, the server may receive a plurality of pieces of car-machine state information at the same time at a certain time, and at this time, the server cannot know the correspondence between each piece of car-machine state information and the previously received instruction information, so that the server may generate a random code (e.g., a random number) after receiving the instruction information and the car-machine identification information sent by the client in step 201.
Then, the server can send the random code to the vehicle machine corresponding to the vehicle machine identification information through a publish-subscribe protocol; the vehicle machine receives the random code through a publish-subscribe protocol, and after vehicle machine state information corresponding to the instruction information is obtained through a java reflection mechanism, the vehicle machine sends the random code and the vehicle machine state information to the server; and the server receives the vehicle machine state information and the random code.
In addition, after the server generates the random code, the server may perform associated storage on the random code and corresponding instruction information, that is, establish a corresponding relationship between the random code and the instruction information, and store the corresponding relationship.
It should be noted that, the step 206 may be executed before the step 202, may be executed after the step 202, may be executed simultaneously with the step 202, and is not particularly limited in this disclosure.
In step 207, target instruction information corresponding to the random code is obtained, and the target instruction information and the vehicle-mounted device state information are stored in an associated manner.
In this disclosure, after receiving the vehicle-machine state information and the random code sent by the vehicle machine, the server may obtain target instruction information corresponding to the received random code according to a corresponding relationship between the random code and the instruction information, and then perform associated storage on the target instruction information and the vehicle-machine state information, that is, establish a corresponding relationship between the instruction information and the vehicle-machine state information, and store the corresponding relationship.
