Specification Name of Invention: A Method and System for Managing Personnel in Special Workplaces

[0001] The present invention relates to the field of smart workplaces, and more particularly to a method and system for managing staff at a particular workplace.

Background technique

[0002] Some special work sites, such as nuclear power plants, oil wells, mines, large terminals or military ports, strategic warehouses, require strict management of their staff due to their special requirements for operations. For example, nuclear power plant personnel, due to the presence of nuclear radiation in certain areas of the nuclear power plant, require the most stringent restrictions on the stay or operational time of workers working in these areas; for example, certain areas of oil wells or mines, gas Or other flammable, explosive or toxic gases have a high concentration, and workers working in these areas, work or staying in the room can not exceed the limit of the day; similarly, those special operations such as large docks, military ports or strategic warehouses Also, strict management of its staff is required for similar reasons.

[0003] In order to solve the problem of managing the above-mentioned special workplace workers, the method used in the industry is to manage the staff in the special workplace by positioning, that is, through some positioning technologies, it is possible to know that these workers are special. The specific location within the workplace, so that it is strictly controlled. At present, the two typical positioning technologies of Global Positioning System (GPS) and Radio Frequency Identification (RFID) are relatively mature. The industry has introduced GPS or RFID into the management of special workplace personnel. However, these two positioning technologies have inherent limitations for the management of staff in special workplaces. Taking GPS technology as an example, its satellite signal is easily blocked by obstacles such as buildings in special work places, and it cannot be accurately positioned. In some special work places, the floor space is huge, the buildings are relatively high, and the relative size needs to be positioned. Smaller workers are obviously unrealistic, while RFID technology is suitable for positioning small objects. However, RFID signals are more susceptible to environmental interference and do not reflect the actual trajectory of the label. For example, Workers move from one location to another in a particular workplace, and RFID does not reflect this process [0004] Therefore, there is a need for new techniques to overcome the deficiencies of the above-described methods for managing personnel at special workplaces. technical problem

The embodiment of the invention also provides a corresponding method for managing a special workplace staff. The details are described below separately. [0041] Please refer to FIG. 1 , which is a schematic flowchart of a method for managing a staff at a special workplace according to Embodiment 1 of the present invention. The method mainly includes the following steps S101 to S103:

[0042] S101. The wristband tag transmits an ultra-wideband pulse signal to at least three base stations.

[0043] In an embodiment of the invention, the wristband label is worn on a staff member at a particular work site. Wristband Labels Ultra Wideband can be sent out periodically without direction or in any direction (Ultra Wide

Band, UWB) Pulse signal. It should be noted that the wristband label is worn on the staff of a special workplace (for example, wrists, ankles, etc.), and it is not easy to fall off naturally from these special workplace workers, once it is artificially destructively forced. Removed from a special workplace worker, the wristband label sends an alarm message.

[0044] At least three base stations of the embodiments of the present invention may be deployed in any jurisdiction of a special work site, and the specific location is capable of receiving an ultra-wideband of sufficient strength to be transmitted by a wristband tag worn on a special workplace worker. The pulse signal is limited.

[0045] It should be noted that the wristband tag transmits an ultra-wideband pulse signal to at least three base stations. In theory, a wireless communication signal that transmits information in any frequency band of 500 MHz in the spectrum of 3.1 GHz to 10.6 GHz can be called an ultra-wideband pulse signal. In the embodiment of the present invention, the ultra-wideband pulse signal may be a signal carried by a wristband tag that occupies any frequency band of any frequency of 3.1 GHz to 10.6 GHz, and the ultra-wideband pulse signal adopts a non-sinusoidal wave of a nanosecond order. Pulse transmission data, with frequency bandwidth (500 MHz), multi-channel, low power consumption, non-interference, high safety factor and coexistence with existing spectrum, that is, it will not interfere with existing and future ultra-wideband communication applications. Therefore, it is possible to perform high-precision positioning for a small-sized worker in a special work place, and to enhance the stability of positioning.

[0046] It should be noted that, in the embodiment of the present invention, at least three base stations are interconnected and synchronized, and the interconnection method may be a wired network interconnection or a wireless network interconnection, where the wireless network includes a WiFi network, a 3G network, a 4G network, and One of the 5G networks. As for the synchronization between the base stations, any one of the at least three base stations may send a synchronization pulse to the at least two base stations directly or through the base station directly connected by the data exchange device, thereby completing the base station and the other at least two base stations. Synchronization between.

[0047] S102. The base station receives the ultra-wideband pulse signal sent by the wristband tag, and sends the engraving of receiving the ultra-wideband pulse signal to the positioning server.

[0048] In the embodiment of the present invention, the positioning server may be deployed in a building of a special work place, for example A positioning server is deployed on every two floors of a building. The positioning server may directly connect to one of the at least three base stations or the plurality of base stations, or the positioning server may connect one of the at least three base stations or the plurality of base stations through the data switching device.

In the embodiment of the present invention, the positioning server connects one of the at least three base stations or the plurality of base stations through the data switching device, and includes the following four connection modes:

[0050] Manner 1: The base station and the base station are connected by a network cable, and one or more base stations are connected to the data distribution port of the router through a network cable, and the data distribution port of the router is connected to the positioning server through the network cable;

[0051] Manner 2: a network cable is connected between the base station and the base station, and one or more base stations are connected to the data distribution port of the switch through the network cable, and the data distribution port of the switch is connected to the positioning server through the network cable;

[0052] Method 3: A fiber connection is used between the base station and the base station, and one or more base stations are connected to the input end of the optical transceiver through the optical fiber, and the output end of the optical transceiver is connected to the positioning server through the network cable;

[0053] Method 4: A fiber connection is used between the base station and the base station, and one or more base stations are connected to the input end of the optical transceiver through the optical fiber, and the output end of the optical transceiver is connected to the positioning server through the network cable.

[0054] In the case that the positioning server is directly connected to one of the at least three base stations or the plurality of base stations, the base station transmitting the address of receiving the ultra-wideband pulse signal to the positioning server may be: at least two of the at least three base stations The base station transmits the moments of the ultra-wideband pulse signals sent by the wristband tags respectively received by the workers on the special workplace to any one of the three base stations, and each of the base stations receives the ultra-wideband pulse signals from each of the base stations. The engraving is directly sent to the positioning server, or each of the at least three base stations directly transmits the engraving of the ultra-wideband pulse signal sent by the wristband tag worn on the special workplace worker to the positioning server; For the case where the positioning server connects one of the at least three base stations or the plurality of base stations through the data switching device, the base station transmits the address of receiving the ultra-wideband pulse signal to the positioning server, which may be: at least two of the at least three base stations Base stations will each receive workers dressed in special workplaces The engraving of the ultra-wideband pulse signal sent by the wristband label of the body is sent to any one of the three base stations, and the engraving of receiving the ultra-wideband pulse signal by each of the base stations is sent to the positioning server through the data exchange device. Or, each of the at least three base stations sends an engraving of the ultra-wideband pulse signal sent by the wristband tag respectively worn on the special workplace worker to the positioning server through the data exchange device.

[0055] S103. The positioning server receives the ultra-wideband pulse signal according to the positioning algorithm and each of the at least three base stations. The special work place staff wearing the wristband label is positioned to send an alarm message to the central server when the staff member stays in the current area for more than the preset time.

[0056] In the embodiment of the present invention, the positioning server calculates the actual coordinate of the wristband label according to the engraving of the at least three base stations each receiving the wristband label to transmit the ultra-wideband pulse signal, and thus the wearable Positioning of special workplace workers with these wristband labels. As for the positioning algorithm, it can be one of the Time Of Arrival (TOA) algorithm and the Time Difference Of Arrival (TDOA) algorithm, or it can be other positioning algorithms.

[0057] It should be noted that, in the embodiment of the present invention, the actual coordinate of the wristband label worn on the staff of the special workplace may be either a two-dimensional coordinate or a three-dimensional coordinate, which depends on For the same wristband tag, how many base stations are used to transmit the ultra-wideband pulse signals respectively received by the wristband tag. For example, if the engraving of the ultra-wideband pulse signals transmitted by the respective receiving wristband tags transmitted by the three base stations is used, the positioning server calculates the actual number of wristband tags worn on the workers of the special workplace. Two-dimensional coordinates, if four or more base stations are used to receive the engraving of the ultra-wideband pulse signal transmitted by the wristband tag, the positioning server calculates the wristband worn on the staff of the special workplace. The actual three-dimensional coordinates of the tag; a typical embodiment uses four or more base stations each receiving the engraving of the ultra-wideband pulse signal emitted by the wristband tag to calculate the wristband tag worn by the worker on a particular workplace. The actual coordinates.

[0058] It should be noted that, in the embodiment of the present invention, since a wristband label is uniquely bound to a special workplace worker wearing the wristband label, and each staff member of the special workplace is special. Each area of the workplace is allowed to enter the database of the location server in advance. Therefore, after receiving the positioning information sent from the wristband label, the positioning server starts counting the stay of the staff wearing the wristband label in its current area. Once the worker's stay in his current area exceeds the preset time, the location server sends an alert message to the central server.

[0059] In the above embodiment, the alarm information is sent by the positioning server to the central server. In the wristband label, there is an alarm module or a speaker 吋. As another embodiment of the present invention, the alarm information can also be sent out by the following means, that is, after receiving the positioning information sent by the wristband label, the positioning server starts to wear The staff of the wristband label is counted at the stop of his current area. Once the staff member stays in the current area for more than the preset time, the location server passes the base station to the staff member. The worn wristband tag sends a trigger command, and the alarm module that triggered the wristband tag sends an alarm message, for example, a sharp beep to remind the worker to leave his current area as quickly as possible.

[0060] The method for managing a special workplace staff as exemplified in FIG. 1 further includes: receiving, by a central server connected to the positioning server, alarm information sent by the positioning server and collecting the positioning server for the staff wearing the wristband label Positioning information for targeting. In the embodiment of the present invention, the central server may be a server located in a central monitoring room in a special work place, or a server deployed by a superior organization outside the special work place and managing the special work place, and the central server may pass The wired or wireless connection is connected to the positioning server deployed in the special working place, and is used for collecting the positioning information of the positioning server for positioning the staff wearing the wristband label, so that the relevant personnel of the special working place can perform the required time. Retrieve or query, and receive the alarm information sent by the positioning server to remind relevant personnel to deal with it.

[0061] In an embodiment of the present invention, the method for managing a special workplace staff as illustrated in FIG. 1 further includes: querying a terminal connected to the central server to query identity information of a staff member wearing a wristband tag and location information. These inquiring terminals can be connected to the central server by wire or wirelessly, and can be either a fixed terminal such as a personal computer (PC) or a mobile terminal such as a smart phone or a tablet. By querying the human-computer interaction interface provided by the terminal, the relevant personnel of the special workplace input the number of the staff of the special workplace, and the identity information and location information of the staff member can be queried, for example, name, title, level, and Where is the current special workplace and so on.

[0062] From the method for managing a special workplace staff as exemplified in FIG. 1 above, the positioning server can perform the engraving of the wristband tag according to the positioning algorithm and the engraving of the ultra-wideband pulse signal by each of the at least three base stations. The positioning is performed, and when the staff member stays in the current area for more than the preset time, the alarm information is sent to the central server. Because the wristband tag worn on the staff of a special workplace sends an ultra-wideband pulse signal, it has the characteristics of frequency bandwidth, multi-channel, low power consumption, low interference, high safety factor and coexistence with the existing spectrum. Therefore, on the one hand, compared with the existing GPS positioning, the technical solution provided by the present invention is not easily affected by environmental interference, and even a small-sized worker in a special working place can perform high-precision positioning; On the other hand, because the wristband label worn on the staff of a special workplace is actually sending an ultra-wideband signal, The bit server can accurately track and locate the staff of the special work place. Therefore, compared with the RFI D positioning technology, the technical solution provided by the present invention can know when the staff of the special work place is at the special work place. Wherever, it can be regulated more effectively.
