[0002] In recent years, the safety production situation of power engineering construction and power plant operation has improved, but due to the complex structure of power plant buildings and equipment systems, there are many staff and great mobility, and the on-site safety hazards show a rapid generation, diversification and dynamic development trend. The traditional safety management mainly relies on safety production management personnel at all levels to conduct on-site supervision, supervise the behavior of production site workers, and manually find and correct violations, which has problems such as low supervision efficiency, weak constraint, and poor timeliness, accuracy and comprehensiveness, so advanced monitoring technology system needs to be adopted to solve and improve.

[0003] At present, the production area management of the power plant mainly has the following problems:

[0004] (1) The daily inspection work management of the production area staff is relatively backward. The traditional inspection is recorded and controlled by manually recording at the inspection point through manual inspection. The inspection information cannot be shared in real time to the internal department, and the management layer cannot master the inspection state of each place in real time, and there is a situation of missing inspection;

[0005] (2) The on-site situation of the production area staff cannot be quickly examined. The traditional attendance is checked by card swiping, which cannot effectively supervise and count the on-site data and personnel distribution. When the power station carries out unit maintenance work, a large number of external personnel are needed to carry out construction such as cleaning, earthmoving, maintenance and maintenance, and it is difficult to avoid that part of the external personnel enter the dangerous area, which has a great safety hazard;

[0006] (3) At present, various supervision and monitoring systems of the power station are relatively independent, such as video monitoring system, personnel management system, production management system and access control system, and the information forms an island by itself, which cannot provide an emergency management platform and comprehensive decision support for managers at all levels, and the management efficiency is low.

Obviously, the described embodiments are some 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 any creative effort belong to the protection scope of the present application.

[0031] The terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above drawings are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or modules is not limited to the listed steps or modules, but can optionally include other steps or modules not listed or can optionally include other steps or modules inherent to the process, method, product or device.

[0032] It should be noted that the terms "first" and "second" involved in the present application are only to distinguish similar objects, and do not represent a specific order of the objects. Understandably, "first" and "second" can be interchanged in a specific order or sequence as allowed. It should be understood that the objects distinguished by "first" and "second" can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those described or illustrated herein.

[0033] It should be noted that the UWB (Ultra-Wide-Band) positioning technology is a wireless communication method that transmits data by using nanosecond-level non-sine wave narrow pulse. The technology uses high bandwidth and fast pulse to realize positioning based on ranging, has the advantages of high precision, low power consumption, easy deployment and strong anti-interference, and is used for high-precision positioning of personnel in complex environments. Compared with other positioning technologies using RSSI (signal strength), it has wider applicability and higher precision.

[0034] Common GPS navigation, Beidou navigation and the like are satellite navigation, and the Beidou / GNSS satellite positioning navigation has the characteristics of supporting BDS / GPS / GLONASS multi-system joint positioning, faster positioning response speed and stronger anti-interference capability, but the positioning accuracy (5-10 meters) cannot meet the requirement of accurate positioning in the factory area, and high-precision positioning (high-precision positioning requirement: 10 cm-50 cm) cannot be realized;

[0035] In one embodiment, as shown in the figure, the application provides an intelligent power plant management system, comprising a positioning system and a comprehensive management platform; wherein the positioning system comprises a UWB positioning subsystem, a video monitoring subsystem and a device monitoring subsystem; Figure 1

[0036] The UWB positioning subsystem comprises a plurality of UWB base stations deployed in the power plant, for detecting the position of a target wearing a portable UWB positioning device within a preset range;

[0037] The video acquisition subsystem is connected with a plurality of image acquisition units deployed in the power plant, for acquiring image information in the area corresponding to each image acquisition unit;

[0038] The device monitoring subsystem is used for monitoring the real-time running state of each unit device in the power plant, and acquiring the running parameters of the unit devices;

[0039] The positioning system uploads the position of the target, the image information and the running parameters to the comprehensive management platform;

[0040] The portable UWB positioning device is a portable device that can be worn or carried, which can be a wearable device such as a bracelet, a watch, a hat, etc., or can be integrated into a safety helmet, a measuring tool, a door card, etc.;

[0041] According to the intelligent power plant management system provided by the application, the UWB positioning subsystem divides the power plant into a plurality of areas according to a preset, binds each UWB base station with a corresponding area according to the position of the UWB base station, configures the permission to enter the area through the tag information built-in in the portable UWB positioning device, establishes a mapping table of the area and the corresponding tag information, and uploads the mapping table to the comprehensive management platform;

[0042] It should be noted that the area can be divided according to the type of the device and the function of the regional cluster device, for example, an area where construction exists is divided into a construction area, and the application does not limit this;

[0043] ​Specifically, for example, in the construction area, when the construction personnel with the safety helmet enters the construction area, the portable UWB positioning device can be integrated into the safety helmet, the UWB positioning base station receives the pulse signal sent by the UWB positioning device on the safety helmet, the UWB positioning base station receives the pulse signal and sends the pulse signal to the tag again, the tag information and the pulse time data obtained are finally sent to the UWB subsystem of the management platform through the transfer and collection equipment, the UWB subsystem calculates the distance between the tag and the positioning base station according to the pulse time of multiple UWB positioning base stations, and then determines the coordinate information of the tag in the construction area, so that the real-time positioning of the on-site construction personnel is realized.

[0044] According to the intelligent power plant management system provided by the application, the UWB base station in each region obtains the position of the target wearing the portable UWB positioning device in the corresponding region, and obtains the tag information of the target, and the position, the tag information and the information of the corresponding UWB base station pair of the target are uploaded to the comprehensive management platform through the UWB positioning subsystem.

[0045] The comprehensive management platform traverses the mapping table to determine whether the target has the permission of the corresponding region, and if not, an alarm information is sent to the corresponding portable UWB positioning device.

[0046] Optionally, the construction personnel entering the construction area obtains the current position information of the tag wearing the portable UWB positioning device from the UWB subsystem through the comprehensive management platform, and if it is detected that the tag is located in the construction area bound by the tag, the construction personnel can check in / check out, otherwise, the construction personnel is not allowed to check in / check out, the number of people checking in and the real-time number of people present are counted in the comprehensive management platform, and intelligent electronic attendance is realized.

[0047] According to the intelligent power plant management system provided by the application, the UWB base station in each region obtains the position of the target wearing the portable UWB positioning device in the corresponding region, and obtains the tag information of the target, and the position, the tag information and the information of the corresponding UWB base station pair of the target are uploaded to the comprehensive management platform through the UWB positioning subsystem.

[0048] Specifically, the portable UWB positioning device carried by the personnel normally working in the construction area sends a positioning pulse signal to the nearby UWB positioning base station every 1 minute, the UWB subsystem collects the positioning information in real time and feeds back to the integrated management platform, and judges that the construction personnel is in the normal online on-duty state; if the construction personnel leaves the construction area arbitrarily during the construction time, the UWB subsystem cannot detect the position information of the tag, and when the integrated management platform does not receive the position information of the tag for a long time, exceeds the off-duty time threshold (such as 3 minutes), an off-duty alarm is sent to the administrator and the individual bound to the tag, and if the off-duty time exceeds the off-duty time threshold (such as 30 minutes), an off-duty alarm is generated.

[0049] According to the intelligent power plant management system provided by the application, the integrated management platform receives alarm information of any portable UWB positioning device, acquires the position of the corresponding portable UWB positioning device through the UWB positioning subsystem, and acquires real-time image information of the position by calling the image acquisition unit of the corresponding position through the video acquisition subsystem.

[0050] According to the intelligent power plant management system provided by the application, at least one tag information built in the portable UWB positioning device is bound to each unit equipment.

[0051] If the device monitoring subsystem detects that the difference between the operating parameters of each unit equipment and the preset operating parameters is greater than a preset threshold, it is judged that the corresponding unit equipment is abnormal, the UWB base station deployed in the preset range of each unit equipment is used to locate the corresponding unit equipment, the tag information bound to the unit equipment is acquired, and the to-be-repaired information is sent to the portable UWB positioning device corresponding to the tag information.

[0052] Specifically, the important unit equipment and the corresponding tag information of the related maintenance personnel and responsible employees are bound on the integrated management platform, and the device monitoring subsystem can acquire the device information, operating parameters and device state of each important unit equipment of the power plant in real time. The system will push the device information to the administrator, the person in charge of the device and the maintenance personnel in real time according to the bound tag information, so that the related personnel can know the device operating state at any time.

[0053] When the integrated management platform detects that there is an abnormal device parameter or an abnormal device operation, it will push a device alarm to the related personnel, and automatically generate a repair task and issue it to the maintenance personnel; when the maintenance personnel enters the production area where the device is located, the permission to enter the related area is configured for the maintenance personnel, the maintenance personnel is automatically identified through the tag and the UWB positioning, and it is displayed in the repair task that the personnel is in the repair process; when the device is repaired, no alarm is generated, and the repair task is automatically completed and closed.

[0054] Due to the actual production environment of the power plant, there are entity walls and a large number of metal shell unit equipments, which have strong absorption interference ability to the positioning pulse wave of UWB, resulting in serious attenuation of the UWB positioning pulse wave and a large reduction in accuracy. By designing the UWB positioning base station as a ceiling type and a wall-hung type, it can be deployed on the wall or the equipment shell, thereby avoiding the absorption interference of the wall and the metal body to the signal.

[0055] In another aspect, the application provides a portable UWB positioning device applied to the system described in any of the above, comprising a communication module, a power module, a positioning module and an image acquisition module.

[0056] The positioning module is used to send a positioning pulse to the UWB base station.

[0057] The communication module is used to communicate with the integrated management platform.

[0058] The image acquisition module is used to acquire image information and upload it to the integrated management platform through the communication module.

[0059] The power module is used to power the positioning device.

[0060] It should be noted that the portable UWB positioning device applied to the above system is a portable device that can be worn or carried, which can be a wearable device such as a bracelet, a watch, a hat, etc., or can be integrated into a safety hat, a measuring tool, a door card, etc.

[0062] The safety hat is composed of a hat shell, a hat belt, a SIM card, a fixed camera on the top of the hat shell, a headset on the side of the hat shell, a charging socket and a label at the back of the hat shell, a control board inside the hat shell, and a multifunctional button on the hat brim, wherein:

[0063] The fixed camera acquires shooting data, the headset acquires voice data, and the alarm module acquires alarm information, and transmits the above data to the management platform through the communication module, while receiving alarm information and voice information from the management platform, and transmitting them to the alarm module and the communication module of the safety hat, respectively.

[0064] In one embodiment, the device is also provided with a multifunctional button, including a switch button, an SOS alarm button, a voice button, and a photographing button; the switch button is connected to the power module to control the power on or off; the SOS alarm button is connected to the alarm module of the control panel to send SOS alarm information to the alarm module; the communication module accesses the wireless router through the SIM card to send voice information, alarm information, and video information generated by the safety helmet to the integrated management platform, and also receives data from the integrated management platform; the photographing button is connected to the fixed camera to send a photographing or video recording instruction.

[0065] Specifically, the UWB positioning tag arranged at the rear of the safety helmet comprises a UWB positioning pulse transceiver and a UWB positioning chip, wherein the UWB positioning pulse transceiver is used to send a positioning pulse to a UWB positioning base station, and the UWB positioning chip is used to control the UWB positioning pulse transceiver to send and respond to the pulse of the UWB positioning base station.

[0066] Further, the field inspection personnel can wear the portable UWB positioning device to count raw materials, check equipment, and conduct quality and safety inspection at the construction site.

[0067] Taking the above safety helmet as an example, if a problem is found, the photographing button on the safety helmet can be pressed to mobilize the fixed camera of the safety helmet to take a photo, and then the photo data and tag information are sent to the integrated management platform through the communication module; when the integrated management platform detects that the user bound to the tag information is a field inspection personnel, a quality and safety problem is added, and an editing permission is opened for the inspection personnel to which the tag belongs.

[0068] Then the field inspection personnel can edit the quality and safety problem through the mobile device bound to the tag, attach an explanation information, and submit it to the background system. After successful submission, the integrated management platform queries the UWB position information when the tag takes a photo through the UWB subsystem, associates to find the construction area and the tag information of each construction personnel under the construction area, pushes the quality and safety problem to the mobile phone APP of each tag personnel, and timely notifies the construction personnel to solve the problem.

[0069] In one embodiment, when the system detects that there is an equipment parameter exception or an equipment operation exception, an equipment alarm is pushed to the related personnel wearing the safety helmet, and a maintenance task is automatically generated and issued to the maintenance personnel. When the maintenance personnel enters the production area where the equipment is located, the maintenance personnel is automatically identified through the tag and the UWB positioning, and it is displayed in the maintenance task that the personnel is in the process of repairing; when the equipment is repaired and no longer produces an alarm, the maintenance task is automatically completed and closed.
