[0002] To meet management requirements related to workshop quality and safety, low-power wireless transmission modules must be able to bind to designated measuring instruments and ensure data security management for legitimate devices. Currently, wireless communication devices and measuring instruments typically connect via a common physical port. Data transmission is enabled when the serial port protocol is consistent, but there is no binding capability. Data filtering is typically performed by the host computer. For example, if measuring instrument information is included in the data transmission, data filtering can be implemented using host computer rules. How to securely bind wireless devices to the module and ensure that networked devices meet security requirements is a pressing issue. Summary of the Invention

[0003] The purpose of the present invention is to provide a low-power wireless module binding measuring tool and security management system and method to solve the problem that the current wireless communication equipment and measuring tools are usually connected using a universal physical port connection and do not have the binding function with the measuring tool.

[0004] In a first aspect, the present invention provides a low-power wireless module binding measuring tool and security management system, comprising: a device management system, a user host computer, a gateway, a wireless access point, a wireless module, and a measuring tool terminal; the device management system and the user host computer are respectively connected to the gateway for communication, the gateway is connected to the wireless access point for communication, the wireless access point is connected to the wireless module for communication, and the wireless module is connected to the measuring tool terminal for communication; The device management system is used to add control access rules for wireless modules that are allowed to access the network, wherein the wireless modules are added by configuring the configuration management rules in the gateway, and a fixed protocol format, IP address and port are configured for the wireless modules to allow communication and transmission between the wireless modules and the user's host computer; The wireless module is used to achieve two-way authentication with the device management system. The wireless module has a built-in authentication key. After power-on, it first sends a key negotiation request to the gateway through the wireless access point. After the device management system confirms that the wireless module is an added wireless module, it automatically issues the key to the wireless module. After the wireless module passes the authentication, it is displayed as online on the device management system. When data is received from the wireless module, data transmission is allowed. The measuring terminal is used to trigger the wireless module to start receiving wireless configuration function when sending data or operating. The device management system sends an instruction of the binding device code allowing binding of the measuring terminal to the wireless module. After receiving the instruction, the wireless module automatically saves the binding device code to the memory storage area as a list of measuring terminals allowed to be bound, thereby completing the measuring terminal binding configuration of the wireless module.

[0005] Furthermore, 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 signal, and the main controller is connected to the wireless radio frequency module signal; the measuring tool terminal is connected to the wireless module interface through a physical connection.

[0006] Furthermore, the wireless module realizes the binding verification function of the measuring tool terminal by collecting the unique identification code of the currently connected measuring tool terminal.

[0007] Furthermore, the unique identification code of the measuring tool terminal is a unique serial number of the measuring tool terminal.

[0008] Furthermore, the binding verification method of the wireless module to the measuring tool terminal is as follows: After the measuring terminal is connected to the wireless module, the wireless module is first awakened before sending data. After being awakened, the wireless module issues a command to query the measuring terminal for a unique identification code. The measuring terminal responds with the unique identification code, and the wireless module saves the unique identification code responded by the measuring terminal to a preset data cache location segment. When the measuring terminal sends the collected data, the wireless module compares the saved unique identification code with the binding device code in the memory storage area one by one. If there is a binding device code that is the same as the unique identification code, the wireless module will package and send the unique identification code and the collected measuring terminal data to the wireless access point, and forward it to the user's host computer through the gateway to process the measuring terminal data; if there is no binding device code that is the same as the unique identification code, the wireless module will send an alarm message to the wireless access point, report the alarm message to the equipment management system and record it.

[0009] Furthermore, the device management system is also used to configure a binding function switch to control whether the binding verification function is enabled.

[0010] Furthermore, the measuring tool terminal is used to send a zero position five times or preset special operations within 5 seconds to control the wireless module to start the function of remotely receiving wireless configuration.

After the device management system confirms that the wireless module is an added wireless module, it automatically issues the key to the wireless module. After the wireless module passes the authentication, it is displayed as online on the device management system. When data is received from the wireless module, data transmission is allowed. The wireless module starts receiving wireless configuration function, configures measuring terminal filtering rules in the device management system, and issues a binding device code instruction of the measuring terminal allowed to be bound to the wireless module. After receiving the instruction, the wireless module automatically saves the binding device code to the memory storage area as a list of measuring terminals allowed to be bound, thus completing the measuring terminal binding configuration of the wireless module; After connecting to the measuring terminal, when the collected data triggers the low-power module of the wireless module to wake up, the wireless module automatically extracts the unique identification code of the current measuring terminal and compares it with the binding device code configured inside the wireless module to confirm whether the measuring terminal is a device that allows binding; if so, the unique identification code and measuring terminal data of the measuring terminal are sent; if not, a non-binding device connection alarm is sent to the device management system.

Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

DETAILED DESCRIPTION

[0015] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. The technical solutions provided by each embodiment of the present invention are described in detail below in conjunction with the drawings.

[0016] See also Figure 1 An embodiment of the present invention provides a low-power wireless module-bound measuring instrument and security management system, comprising: a device management system, a user host computer, a gateway, a wireless access point, a wireless module, and a measuring instrument terminal. The device management system and the user host computer are respectively connected to the gateway, the gateway is connected to the wireless access point, the wireless access point is connected to the wireless module, and the wireless module is connected to the measuring instrument terminal. The device management system has a wired connection to the gateway and the wireless access point, and is wirelessly connected to the wireless module via the wireless access point, enabling the transmission and reception of control commands and data.

[0017] In the device management system, security administrators can add access control rules for wireless modules that are allowed to access the network. This involves configuring configuration management rules within the gateway, adding wireless modules, and configuring fixed protocol formats, IP addresses, and ports for them to allow communication with the host computer. For example, wireless module 1 can be configured to use the UDP protocol for transmission, assigned an IP address and port, and the user host computer's receiving IP address and port to complete the data transmission rule configuration. Otherwise, the authentication key cannot be issued, the device management system will not display the device, and the relevant data information requested by the device will be filtered.

[0018] The wireless module and the device management system feature bidirectional authentication. The wireless module has a built-in authentication key. Upon power-up, it first sends a key negotiation request to the gateway. Once the device management system confirms that the module is a legitimate device, the key is automatically issued to the wireless module. Once the wireless module passes authentication, it will appear online on the device management system. When receiving data from the wireless module, normal data transmission is allowed. Otherwise, the module displays an unauthenticated status and data transmission is blocked.

[0019] When the measuring terminal sends data or operates, it triggers the wireless module to start the wireless configuration receiving function. The device management system sends an instruction to the wireless module to allow the binding of the measuring terminal with the binding device code. After receiving the instruction, the wireless module automatically saves the binding device code to the memory storage area as a list of measuring terminals allowed to be bound, completing the measuring terminal binding configuration of the wireless module.

[0020] See also Figure 2The wireless module includes a low-power module, a data acquisition and wake-up module, a main controller, and a wireless RF module. The low-power module and the data acquisition and wake-up module are respectively connected to the main controller for signal connections, which in turn are connected to the wireless RF module for signal connections. The measuring terminal is physically connected to the wireless module interface. The wireless module can perform binding verification on the measuring terminal by collecting the unique identification code of the currently connected measuring terminal. For example, the unique identification code of the measuring terminal is the measuring terminal's unique serial number (SN).

[0021] In this embodiment, the wireless module verifies the binding of the measuring tool terminal as follows: First, the measuring instrument must reset itself to zero five times within 5 seconds, or perform a special operation such as a long button press, to control the wireless module's ability to remotely receive wireless configurations. A security administrator can log in to the device management system to configure measuring instrument filtering rules and send the wireless module the unique serial numbers of designated measuring instrument terminals that are allowed to be bound. This can be a combination of ten digits and letters, with multiple serial numbers separated by semicolons (;). Upon receiving this instruction, the wireless module writes all unique identification codes to memory, recording the unique serial numbers of all bound measuring instruments and ensuring that this information can be read even after power is cycled. This completes the binding configuration between the wireless module and the measuring instrument terminal.

[0022] After the measuring terminal connects to the wireless module, before sending data, the measuring terminal triggers the wireless module's low-power module to wake up. After waking up, the wireless module first extracts the unique serial number of the currently connected measuring terminal. For example, the serial port sends "SN?" and waits for the measuring terminal to reply with an SN code. Alternatively, if the measuring terminal transmits data with the SN code, the SN code can be extracted based on the data format. For example, if the format is SN code + @ + data, the SN code before the @ can be directly extracted. Different measuring terminals have different methods for obtaining SN codes, so this function needs to be adapted to each measuring terminal.

[0023] The wireless module compares the collected unique serial number of the measuring instrument terminal with the stored binding device code to confirm whether it is a bound device. If so, the measuring instrument terminal SN code is stored in the sending buffer. When the measuring instrument terminal sends data, the measuring instrument SN code + measuring instrument terminal data are normally packaged and sent, which can be forwarded to the user's host computer through the gateway. If not, an unbound device connection alarm message is immediately sent, which is forwarded by the gateway to the device management system, triggering a pop-up window on the page to notify the security administrator of the unbound measuring instrument warning and recording the alarm log in the system.

[0024] See also Figure 3 The embodiment of the present invention provides a low-power wireless module binding measuring tool and security management method, which is applied to the above low-power wireless module binding measuring tool and security management system, including: The device management system adds control access rules for wireless modules, adds wireless modules by configuring configuration management rules in the gateway, and configures fixed protocol formats, IP addresses, and ports for the wireless modules, allowing communication and transmission between the wireless modules and the user's host computer; The wireless module and the device management system have a two-way authentication function. The wireless module has a built-in authentication key. After power-on, it first sends a key negotiation request to the gateway through the wireless access point. After the device management system confirms that the wireless module is an added wireless module, it automatically issues the key to the wireless module. After the wireless module passes the authentication, it is displayed as online on the device management system. When data is received from the wireless module, data transmission is allowed. The wireless module starts receiving wireless configuration function, configures measuring terminal filtering rules in the device management system, and sends the binding device code of the measuring terminal allowed to be bound to the wireless module. After receiving the command, the wireless module automatically saves the binding device code to the memory storage area as the list of measuring terminals allowed to be bound, completing the measuring terminal binding configuration of the wireless module; After connecting to the measuring terminal, when the collected data triggers the low-power module of the wireless module to wake up, the wireless module automatically extracts the unique identification code of the current measuring terminal and compares it with the binding device code configured inside the wireless module to confirm whether the measuring terminal is a device that allows binding; if so, the unique identification code and measuring terminal data of the measuring terminal are sent; if not, an unbound device connection alarm is sent to the device management system.

[0025] As can be seen from the above embodiments, the present invention adopts a method for wireless module binding measuring tool terminal information verification and wireless module data security management to ensure the low power consumption requirements of the wireless module and ensure that the currently connected measuring tool terminal is a measuring tool that meets the requirements. Through the remote configuration of the device whitelist by the security management system, it is sent to the wireless module for memory storage, and real-time measuring tool information verification is performed during data transmission, thereby realizing the security binding function of the device. At the same time, it can realize the security management of the wireless module and data transmission configuration related functions, ensuring the data security of the networked device in each communication stage of the transmission system. Solving the binding requirements of low-power module devices for measuring tools, the binding information can be changed by remote configuration to realize the security management of the measuring tool equipment connected to the network on site.
