It is widely used in factory management systems, such as water plant management. The operation and maintenance of filtration equipment, oxidation equipment, disinfection equipment, pumping stations and other equipment in the water plant require clear equipment information. Using NFC to record equipment information allows staff to quickly obtain equipment information.

[0004] This patent uses NFC tags to record inspection information and determine the type of equipment failure. However, the equipment failure type or inspection information can be directly transmitted to the control room remotely via wireless communication, and the characteristics of NFC tags cannot be brought into play. Currently, in the operation and management of water plants, NFC tags are used as identity recognition to manage personnel entering and exiting various equipment rooms, thereby achieving a security management effect. However, during personnel operations, it is impossible to limit personnel permissions based on NFC tags, which can easily lead to safety hazards caused by personnel with insufficient permissions operating equipment.

[0040] Figure 1 This is a schematic diagram of a water plant operation management system based on NFC tags of the present invention;

[0041] Figure 2 This is a schematic diagram of a water plant operation management method based on NFC tags of the present invention. DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1

[0044] See also Figure 1As shown, the water plant operation and management system based on NFC tags described in this embodiment includes a data collection module, a data processing module, a model training module, an analysis module and a dynamic permission module, and each module is connected through a wired and / or wireless network.

[0045] The data collection module is used to collect i device permission levels, personnel location data and personnel information data.

[0046] The data processing module calculates the permission level between devices based on the i device permission levels. The permission level between devices is used as the basic data of the NFC identification terminal between devices. The NFC tag is made based on the personnel information data, that is, the personnel information data is written into the NFC tag, such as a card that supports identity identification. The NFC tag is matched with the basic data of the NFC identification terminal between devices to determine whether the person can enter the device room. If the personnel information data in the NFC tag matches the basic data of the NFC identification terminal, it is determined that the person can enter the device room. If the personnel information data in the NFC tag does not match the basic data of the NFC identification terminal, it is determined that the person can enter the device room.

[0047] The purpose is that as the authority level of i equipment changes, the authority level between equipment is also adjusted accordingly, which facilitates the scheduling of personnel for water plant operation and management and makes better use of human resources;

[0048] For example, in the pump room of the equipment room of a water plant, the pump station equipment has dangers such as high pressure and high temperature, and careless operation may cause safety risks such as squeezing and scalding. Therefore, the pump station equipment in the pump room needs to be repaired by professionals, but the normal inspection does not necessarily require professionals who can repair the pump station equipment. If the authority between the equipment rooms is consistent, for safety reasons, the authority should be limited to professionals who can only repair the pump station equipment, and the inspection work can only be carried out by professionals who can repair the pump station equipment. If the professionals who can repair the pump station equipment work at other sites or take leave, the inspection work of the pump room will be insufficient. However, under normal circumstances, ordinary personnel can perform the inspection work of the pump room. If the dynamic authority of the present embodiment is used, the authority level of the equipment room can be adjusted according to the actual situation.

[0049] It should be noted that this embodiment only takes a single pump room as an example. If the equipment in the equipment room is of various types and employs a large number of people, the benefits of dynamic permissions on personnel scheduling can be more realized, and no further elaboration will be given here.

[0050] The analysis module calculates the distance value between the personnel and the non-matching authority device based on the personnel location data, and the personnel location data includes the personnel location information and i equipment location information; the personnel location information is the distance between the ground position of the personnel and the laser radar; the i equipment location information is the distance between the i equipment and the laser radar; the method for calculating the distance value between the personnel and the non-matching authority device includes: sequentially calculating the spacing values ​​between the equipment corresponding to the personnel category of non-matching and the personnel, and obtaining g spacing values, g is an integer greater than or equal to 0; selecting the minimum value of the g spacing values ​​as the distance value; for example, although ordinary personnel can enter the equipment room to perform inspection-type low-risk work, the authority level of the equipment room will be comprehensively judged based on the authority level of the internal equipment in the equipment room. Ordinary personnel match the authority level of the equipment room and enter the equipment room, which does not mean that the personnel can operate all equipment. Therefore, in order to avoid the personnel from mistakenly operating the equipment that does not match their equipment authority level, the distance value of the personnel from the non-matching authority device is calculated, and the distance value is used to judge the possible danger of the personnel;

[0051] It is worth mentioning that the distance between a person and i devices can be calculated by triangulation. Triangulation is a known and public calculation method and will not be elaborated on here.

[0052] Personnel information data includes personnel facial video data and personnel authority level; specifically, the facial video data of personnel in the equipment room is obtained by pre-shooting with the camera in the equipment room, and the personnel authority level represents the ability of the personnel. For example, each level corresponds to the type of equipment that can be operated and the equipment situation that can be dealt with. The facial video data of the personnel is used for facial recognition. The purpose is to bind the personnel skill level with the facial video data of the personnel. In this way, even if the NFC tag used by the non-person matches the basic data of the NFC recognition end between the devices and enters the equipment room, it will be judged as a dangerous behavior. Alternatively, the NFC recognition end is equipped with a face recognition device, which can cooperate with the NFC recognition end to authenticate the personnel entering the equipment room. The personnel recognition model training method is described below;

[0053] Match the personnel information data with the device permission level. When the personnel information data and the device permission level match, the corresponding actual label is 0, and when the personnel information data and the device permission level do not match, the corresponding actual label is 1; use the personnel information data and the device permission level as the input of the personnel identification model, the personnel identification model uses the predicted label of each group of personnel information data and device permission level as the output, the actual label as the prediction target, and minimizes the sum of the prediction accuracy of all personnel information data and device permission levels as the training target; wherein the calculation formula for prediction accuracy is: zk = (ak-wk) 2, wherein k is the number of the personnel information data and the device authority level, zk is the prediction accuracy, ak is the predicted labeling value corresponding to the k-th group of personnel information data and the device authority level, and wk is the actual labeling corresponding to the k-th group of personnel information data and the device authority level; the personnel identification model is trained until the sum of the prediction accuracies converges. It should be noted that the convergence standard is determined by technical personnel in this field according to actual conditions, and the training is stopped and the trained personnel identification model is used as the personnel identification model; the personnel identification model is any one of a two-stream convolutional neural network model or a 3D convolutional neural network model.

[0054] The dynamic permission module generates a danger factor based on personnel category and distance value, sets a danger factor threshold and generates a danger instruction by comparing and analyzing the danger factor, and adjusts personnel permissions based on the danger instruction; specifically: compare and analyze the danger factor with a preset danger factor threshold; if the danger factor is greater than or equal to the preset danger factor threshold, a danger instruction is generated, and based on the danger instruction, the personnel authority is reduced and a warning is issued, thereby improving the personnel's safety awareness; if the danger factor is less than the preset danger factor threshold, no danger instruction is generated; it is worth mentioning that the danger factor threshold is determined by technical personnel in this field according to actual conditions. The higher the danger factor threshold is set, the lower the sensitivity of judging dangerous instructions.
