Detailed Description

Optionally, the monitoring information of the tunnel and the bridge in step S1 includes: bridges, tunnel deformation information, traffic flow information, metal fatigue information, and the like. Various monitoring information has different related sensitivity degrees, so that corresponding safety levels need to be configured, for example, the monitoring information is divided into high, low and medium levels, and can be divided in more detail. In addition, because the attributes of the monitoring information are different, for example, the possible data volume of some information is relatively small, and the data volume of some monitoring information is relatively large, for example, video format data, a sending method in different modes can be adopted; and because the requirements for different monitoring information are different, some monitoring information needs to be acquired in real time, and some monitoring information can be acquired in a longer time period, the corresponding sending mode and sending period of the monitoring information can be configured. The acquisition device monitors various monitoring information and has the functions of data transmission and data processing.

the first transmission mode is a short-range transmission mode, and the range of the short range may be set autonomously, for example, by means of NFC transmission. The second transmission mode is a transmission mode of wireless relay, for example, a transmission mode through a 4G wireless network.

and S6, selecting the encryption mode of the information by the acquisition device according to the corresponding security level information, processing the monitoring information, sending the processed monitoring information to the second server, and ending.
By implementing the embodiment, the acquisition device selects the sending mode corresponding to the monitoring information according to the sending mode; when the user terminal belongs to the first sending mode, the acquisition device verifies the identity of the user terminal and then sends monitoring information, and the process is finished; when the monitoring information belongs to the second sending mode, the acquisition device selects an encryption mode of the information according to the corresponding safety level information, processes the monitoring information, sends the processed monitoring information to the second server, and ends; the method and the device can distinguish the types of the monitoring information, select different information sending modes and encryption modes, and ensure the safety in the information transmission process.
As shown in fig. 1, in the method for remotely sending bridge tunnel monitoring information based on the internet of things according to the present invention, the step S5 includes:
s51, the user terminal sends an identity authentication request to the second server, wherein the identity authentication request carries an identification number corresponding to the user terminal;
s52, the second server judges whether the user terminal initiating the request is in the user terminal cluster according to the corresponding identification number of the user terminal, and the second server sends the verification passing information to the acquisition device when the user terminal cluster is in the user terminal cluster; the acquisition device confirms that the user passes the verification according to the verification passing information and sends acquisition device information to the user terminal;
s53, the second server generates an authorization instruction with a term according to the sending period and sends the authorization instruction to the user terminal; the user terminal sends the authorization instruction to the acquisition device in an NFC mode; the acquisition device verifies the authorization instruction, and the step goes to step S54 after the authorization instruction passes the verification;
s54, the user terminal sends an activation request to a first server, the activation request carries information of a corresponding acquisition device, the first server judges whether the activation request is matched with activation conditions of firmware issuing, and the first server acquires the firmware corresponding to the acquisition device and issues the firmware to the corresponding acquisition device when the activation request is matched with the activation conditions of the firmware issuing;
and S55, the acquisition device sends the monitoring information to the user terminal in an NFC mode.
In this embodiment, whether the user terminal initiating the request is in the user terminal cluster is judged by the identification number corresponding to the user terminal, so that the first-layer verification function is exerted; and by setting the authorization instruction with the term, the monitoring information can be sent to the user terminal in an NFC mode only in the period when the authorization instruction with the term is effective, so that the safety of information transmission is further guaranteed. And the first generation of the authorization instruction with the term is to conform to the sending period and is generated by the second server, and the safety of the generation of the authorization instruction with the term is ensured through the two limits. The specific duration of "with deadline" here may be set autonomously.

in this embodiment, the splitting factor in the first splitting may be generated by the original splitting factor and the splitting factor update rule; when the splitting is needed again in the follow-up, the splitting factor obtained last time is updated through the splitting factor updating rule, and then the needed splitting factor can be obtained. Only the latest split factor is kept at a time, and the update is performed by the split factor update rule. The second server and the acquisition device can update the splitting factor through the rule. It should be noted that, for the splitting factor and the splitting rule, the present invention is not limited specifically, and the splitting of the monitoring information can be implemented. In a simpler embodiment, the original split factor is set to 2, and the split factor update rule is: "Add 2" is performed for each update. For example, the splitting factor is 4 at the first update and 6 at the next update; accordingly, the splitting rule is to divide the monitoring information by the splitting factor to obtain the splitting information. More complex ways of updating and splitting are also possible. The significance of this step is that the rule is not always regular when monitoring information is split every time, and even if someone else obtains split information once, how to split next time cannot be predicted.

Specifically, when there are a plurality of acquisition devices, another detection device may be selected as the relay node.
