Description
Technical Field
The present invention relates to the field of internet of things, and in particular, to a device searching method, system, apparatus, computer device, and storage medium.
Background
In the field of internet of things, a general communication mode comprises 4G communication (such as mobile phone traffic) and local area network communication, wherein the 4G communication is to search for designated equipment in an internet environment through a PC (personal computer) in a factory test, judge whether the equipment is online or not, and aim to detect whether the equipment is online or not, and then p2p communication can be performed after the equipment is online so as to realize the communication between the equipment and the PC.
In the prior art, a serial data line is always inserted on a PC, and the serial data line has the function of being electrified and communicated. The basic logic of the equipment end is that after the equipment is started and networked, two threads are started: thread 1, the equipment actively sends a request of the local MAC to a server, and the server marks the MAC record sent by the equipment as online in a database; and the thread 2 and the equipment monitor whether new serial port connection exists or not, and if so, the local MAC is sent to the PC end through the serial port. The basic logic of the PC terminal is to monitor whether the serial port has data to send or not, if the serial port has the data to send, the server sends a query request to the acquired equipment MAC through the HTTP protocol, the server queries whether the equipment MAC exists in the database according to the request, and if the equipment MAC exists in the database, the server records that the equipment is on line. After the product is tested, the PC sends a deleting request to the server through the HTTP protocol by using the obtained device MAC, and the device MAC tested before is deleted in the database.
However, the prior art has some objective disadvantages that not all devices have serial ports (for example, microUSB, type-C) for external connection, resulting in low compatibility and no wide application. In addition, the device needs to send the local MAC to the server by connecting the external network, and also needs to monitor the serial port connection, and send the local MAC to the PC by utilizing the serial port, so that hardware resources are wasted, and the MAC can be artificially changed, so that the uniqueness of the MAC is not strong. After the product is tested, if the network problem or the software crash and other problems occur, the server database can permanently store the tested equipment MAC, and the memory space of the server is wasted.

Example 1
The method aims at solving the problems that in the prior art, due to the serial port of the out-of-band connection of equipment, the compatibility is low and the equipment cannot be widely used; the equipment end is required to be simultaneously connected with the external network to send the local MAC to the server and simultaneously monitor the serial port connection, and the serial port is utilized to send the local MAC to the PC end, so that very wasted hardware resources are caused; the uniqueness is not strong because the MAC can be artificially altered; if a network problem or a software crash occurs in the middle of the network problem, the server database permanently stores the tested device MAC, and the server memory space is very wasted, as shown in fig. 1, which is a flowchart of a device searching method applied to a device end in an embodiment of the present application, where the device searching method applied to the device end provided in the embodiment of the present application is applied to a device searching system, and specifically includes the following steps:
step S110, verifying whether the equipment end is started and successfully surfing the Internet, and reading the unique identification of the SIM card on the equipment end.
In this embodiment, the device search system includes: the device search is performed by using the MQTT protocol, the PC end serves as a subscriber of the MQTT protocol, the device end serves as a publisher of the MQTT protocol, because the 4G communication needs to use SIM cards, each SIM card has a corresponding unique identifier-ICCID, the ICCID is used as the unique identifier of the device end in the embodiment, because the device end is used for product test, all the device ends can repeatedly use the same SIM card for test, for example, each test station is distributed with 4 SIM cards, at most 4 devices can be tested each time, and the SIM cards are unplugged and plugged into the next device to be tested for use after the test is finished.
Specifically, it is first required to ensure that the device is powered on, and after the power on is completed, it is detected whether the connection between the WAN port of the device and the external network is successfully established. When the equipment end is started and surfing the internet successfully, the unique identifier ICCID of the SIM card inserted on the current equipment end is read.
The method uses ICCID as the unique identifier of the equipment, and the ICCID in the SIM card is read every time and cannot be changed artificially, so that the uniqueness is stronger.
And step S120, issuing an identification theme to the MQTT server through 4G communication, setting a preset issuing period, and issuing the identification theme once every other preset issuing period.
Further, the identification theme < ICCID > _device with the RETAIN flag bit of 0 is issued to the MQTT server by the MQTT protocol through 4G communication, and the unique identification of the Device side is written into the identification theme (e.g. 123546_device), where the identification theme includes information that the Device side performs P2P communication with the PC side.
It can be appreciated that in this embodiment, a preset release period needs to be set, and the identification theme is released once every preset release period. Since the traffic of the SIM card on the device side needs to be used for issuing the identification theme, in order to save traffic, the issue is controlled to be performed once every preset issue period, and the preset issue period may be 2 seconds, 3 seconds or 5 seconds, which is not limited in the embodiment of the present application.
The RETAIN flag bit is set to 0 by utilizing the MQTT protocol, so that the MQTT server can not register the identification theme and a local database is not required, the memory space of the MQTT server is greatly saved, and the PC end can immediately receive the release content every time the equipment subscribes the identification theme, so that the real-time performance is stronger.
It should be noted that MQTT is a message transmission protocol based on a publish/subscribe mode of server architecture. It was originally developed by IBM corporation and designed as a lightweight, open, simple and easy to implement messaging protocol. MQTT is well suited for application to message communication between environmentally limited (narrowband, high-latency, unreliable network environments) machines and machines (M2M), internet of things (IoT) devices. It has found widespread use in communicating sensors, occasionally dialed medical devices, smart homes, and some miniaturized devices over satellite links.
The method does not need serial communication, so that the compatibility is stronger, the method is more widely used, and the PC end can search only by using the < ICCID > _device as an identification theme and releasing the P2P communication information as content by using the MQTT protocol equipment end, thereby greatly saving hardware resources.
Step S130, judging whether the equipment end normally performs P2P communication with the PC end;
step S140, if the identification theme is normal, stopping issuing the identification theme;
step S150, if abnormal, reissuing the identification theme.
Further, it is determined whether the device side performs P2P communication with the PC side normally, if so, the issuing of the identification theme is immediately stopped, and if not, the process jumps to step S120 to reissue the identification theme.
It should be noted that, the device side sends a P2P communication request message to the PC side, and when the PC side determines that the authentication information carried in the P2P communication request message sent by the device side is legal, the PC side sends a P2P communication acknowledgement message to the device side, so as to determine whether the device side performs P2P communication with the PC side normally according to whether the above process is correct.
According to the device searching method applied to the device end, whether the device end is started up or not is verified, the device is successfully connected to the internet, and the unique identification of the SIM card on the device end is read; issuing an identification theme to an MQTT server through 4G communication, setting a preset issuing period, and issuing the identification theme once every other preset issuing period; and judging whether the equipment end normally communicates with the PC end in P2P mode, if so, stopping issuing the identification theme, and if not, reissuing the identification theme. The invention has stronger compatibility without serial port communication, can lead the PC end to search immediately by issuing the identification subject, has stronger instantaneity, saves hardware resources, and has stronger uniqueness because the unique identification of the SIM card on the equipment end is not manually changeable.
Example 2
As shown in fig. 2, in an embodiment of the present application, a flowchart of a device searching method applied to a PC side, where the device searching method applied to the PC side provided in the embodiment of the present application includes the following steps:
step S210, searching the equipment end, and searching whether the local database of the PC end contains a unique identifier.
Step S220, if the unique identifier is included, the memory used for storing the unique identifier in the local database is emptied.
The "search device" button popped up on the PC end-click page to search for the device end. In general, a unique identifier ICCID is stored in a local database at the PC end, the ICCID can be reused, a user only needs to add the unique identifier ICCID once, the unique identifier ICCID can be used all the time later, data cannot be cleared after product test software or a computer is restarted, repeated addition is not needed, and the test of the search equipment is continued.
Further, whether the unique identifier ICCID is stored or not is searched in the local database, and if the unique identifier ICCID is contained, the memory for storing the unique identifier in the local database needs to be emptied in order to prevent data repetition.
If the unique identifier is not contained, popping up an interface for managing ICCID, prompting a user to fill in the unique target identifier of the target equipment end to be searched, and searching again whether the unique target identifier is contained in the local database.
And step S230, subscribing the identification topics corresponding to all the unique identifications stored in the MQTT server, and judging whether the corresponding unique identifications are contained in the local database when the equipment end is searched.
It should be noted that, the MQTT server stores an identification theme < ICCID > _device corresponding to the unique identification, and subscribes to all the identification themes. Since the searching device consumes PC hardware resources, in order to limit the time of searching the device end, a preset searching period is set, and the device end is searched once every preset searching period, in this embodiment, the preset searching period may be 2 seconds, 3 seconds or 5 seconds, which is not limited in this embodiment of the present application.
Further, whether the equipment is searched or not is judged, if the equipment is not searched, a preset searching period is reset, and if the equipment is searched, whether the unique identifier corresponding to the equipment is contained in the local database is continuously judged.
Through subscribing the identification theme stored in the MQTT server, the PC terminal can immediately receive the identification theme every time the equipment terminal publishes the identification theme, and the instantaneity is stronger.
Step S240, if not included in the local database, storing the corresponding unique identifier and the identifier theme in the local database, and selecting one device side to perform P2P communication with the PC side.
If the unique identifier ICCID corresponding to the searched equipment is contained in the local database, the unique identifier ICCID is not required to be stored in the local database; if the unique identification ICCID is not contained in the local database, the unique identification ICCID of the searched equipment and the corresponding identification subject are required to be stored in the local database in order to prevent the data stored in the local database from being repeated.
Further, a unique identifier ICCID selected by a user is obtained, and the unique identifier ICCID and a preset question-answering mechanism are connected with a designated equipment end to perform P2P communication with a PC end.
It may be understood that, in this embodiment, the preset question-answering mechanism includes some communication questions for matching the unique identifier with the security of the device side, and the specific content may be determined according to the actual situation, which is not limited in this embodiment of the present application.
According to the device searching method applied to the PC end, whether the local database of the PC end contains the unique identifier is searched through the searching device end; if the unique identifier is contained, the memory used for storing the unique identifier in the local database is emptied; subscribing all identification topics corresponding to the unique identifications stored in the MQTT server, and judging whether the corresponding unique identifications are contained in the local database when the equipment end is searched; if the device is not contained in the local database, storing the corresponding unique identification and the identification theme into the local database, and selecting one device side to perform P2P communication with the PC side. The method and the device have the advantages that serial port communication is not needed, compatibility is higher, the identification theme can be searched in real time through subscribing the identification theme by the PC side, instantaneity is higher, and hardware resources are saved.
