[0026] To make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with the specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application. The technical solutions provided by the embodiments of the present application will be described in detail below in connection with the drawings.

[0027] Referring to Figure 1 The low-power wireless module binding gauge and security management system provided by the embodiments of the present application comprises a device management system, a user host computer, a gateway, a wireless access point, a wireless module and a gauge terminal. The device management system and the user host computer are in communication connection with the gateway, the gateway is in communication connection with the wireless access point, the wireless access point is in communication connection with the wireless module, and the wireless module is in communication connection with the gauge terminal. The device management system is in wired connection with the gateway and the wireless access point, is wirelessly connected to the wireless module through the wireless access point, and can realize the transmission of control instructions and data.

[0028] The security administrator in the device management system can add the control access rule of the wireless module allowed to access the network, that is, by configuring the configuration management rule in the gateway, the wireless module is added, and the wireless module is configured with a fixed protocol format, an IP address and a port, and is allowed to communicate and transmit with the host computer. For example, the wireless module 1 can be configured to use the UDP protocol for transmission, and is allocated an IP address and a port, and the user host computer is simultaneously configured to receive the IP address and the port, so as to complete the configuration of the data transmission rule. Otherwise, the next step of issuing the authentication key cannot be performed, the device management system does not display the device, and the related data information requested by the device is filtered.

[0029] The wireless module and the device management system have a bidirectional authentication function. The wireless module is built-in with an authentication key, and after power-on, the wireless module first sends a key negotiation request to the gateway. After the device management system confirms that the wireless module is a legal device that has been added, the authentication key is automatically issued to the wireless module. After the wireless module passes the authentication, the device management system normally displays the online state of the wireless module, and when the data of the wireless module is received, the normal data service data transmission is allowed. Otherwise, the device displays an unauthenticated state, and the data transmission is blocked.

[0030] The wireless module is triggered to start receiving wireless configuration function when the gauge terminal sends data or operates. The device management system sends an instruction to the wireless module to allow binding of the gauge terminal, and the wireless module automatically saves the binding device code in the memory storage area as the list of allowed binding gauge terminals, completing the wireless module binding configuration of the gauge terminal.

[0031] Please refer to Figure 2 The wireless module includes a low-power module, a data acquisition wake-up module, a main controller, and a wireless radio frequency module. The low-power module and the data acquisition wake-up module are respectively connected to the main controller, and the main controller is connected to the wireless radio frequency module. The gauge terminal is connected to the wireless module interface through physical connection. The wireless module can realize the binding verification function of the gauge terminal by collecting the unique identification code of the currently connected gauge terminal. For example, the unique identification code of the gauge terminal is the unique serial number (Serial No, SN) of the gauge terminal.

[0032] In this embodiment, the wireless module binding verification method of the gauge terminal is as follows:

[0033] First, the wireless module is controlled to start the remote receiving wireless configuration function by sending the zero position five times within five seconds or performing special operations such as long-pressing the button. The security administrator can log in to the device management system to configure the gauge filtering rule and send the specified unique serial number of the allowed binding gauge terminal to the wireless module, for example, ten digits and letter combination, and multiple serial numbers can be separated by semicolons “;”. After receiving the instruction, the wireless module writes all the unique identification codes into the memory storage, records all the unique serial numbers of the bound gauges, ensures that the memory information can be read after power-off, and completes the binding configuration of the wireless module and the gauge terminal.

[0034] After that, the gauge terminal is connected to the wireless module, and the low-power module of the wireless module is triggered to wake up before the gauge terminal sends data. After the wireless module is woken up, the unique serial number of the currently connected gauge terminal is extracted first. For example, the serial port sends “SN?” and waits for the gauge to reply the SN code, or the gauge terminal directly transmits the data with the SN code, which can be extracted according to the data format, such as SN code + @ + data, which can directly extract the SN code before @. The SN code acquisition method of different gauge terminals is different, and specific adaptation of the function to different gauge terminals is required.

[0035] The wireless module compares the collected unique serial number of the gauge terminal with the stored binding device code one by one, and confirms whether it is a binding device. If yes, the gauge terminal SN code is stored in the sending buffer, and when the gauge terminal sends data, the gauge SN code + gauge terminal data are normally packaged and sent, which can be normally forwarded to the user host computer through the gateway; if not, non-binding device connection alarm information messages are immediately sent, which are forwarded to the device management system by the gateway, triggering a non-binding gauge warning pop-up window on the page to inform the safety administrator, and at the same time, an alarm log is recorded in the system.

[0036] Please refer to Figure 3 The embodiment of the application provides a low-power wireless module binding gauge and safety management method, which is applied to the above low-power wireless module binding gauge and safety management system, and comprises the following steps of:

[0037] The device management system adds control access rules of the wireless module, adds the wireless module by configuring the configuration management rules in the gateway, and configures fixed protocol formats, IP addresses and ports for the wireless module, so as to allow the wireless module to communicate and transmit with the user host computer.

[0038] The wireless module and the device management system have a bidirectional authentication function. The wireless module is internally provided with an authentication key. After power-on, the wireless module first sends a key negotiation request to the gateway through a wireless access point. The device management system automatically issues a key to the wireless module after confirming that the wireless module is an added wireless module. After the wireless module passes the authentication, the wireless module is displayed online on the device management system, and data transmission is allowed when data of the wireless module is received.

[0039] The wireless module starts to receive the wireless configuration function. The device management system configures gauge terminal filtering rules, and issues an instruction of a binding device code of a binding gauge terminal to the wireless module. The wireless module automatically saves the binding device code in the memory storage area as a list of allowed binding gauge terminals after receiving the instruction, and completes the binding configuration of the wireless module.

[0040] After connecting the gauge terminal, when the data collection triggers the low-power module of the wireless module to wake up, the wireless module automatically extracts the unique identification code of the current gauge terminal, and compares it with the binding device code configured in the wireless module to confirm whether the gauge terminal is an allowed binding device. If yes, the unique identification code of the gauge terminal and the gauge terminal data are sent, and if not, a non-binding device connection alarm is sent to the device management system.

[0041] From the above embodiments, the method for wireless module binding, gage terminal information verification and wireless module data security management is adopted, the low power consumption requirement of the wireless module is ensured, and it is ensured that the currently connected gage terminal is a required gage. Through the mode of remotely configuring the device white list by the security management system, the device white list is issued to the wireless module for memory storage, real-time gage information verification is performed during data transmission, and thus the security binding function of the device is realized. Meanwhile, the security management of the wireless module and the related functions of data transmission configuration can be realized, the data security of the network access device in each communication stage in the transmission system is ensured. The binding requirement of the low power consumption module device to the gage is solved, the binding information can be changed through remote configuration, and the security management of the gage device accessed in the field is realized.

[0042] The above-mentioned embodiments of the present application do not constitute a limitation on the protection scope of the present application.
