All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments of the present disclosure, shall fall within the scope of protection of the present application.
In order to solve the problems mentioned in the background art, embodiments of the present specification provide a method and an apparatus for monitoring the safety of a park operator, which are applied to a personnel positioning system. The personnel positioning system comprises a reference station, a positioning beacon and a positioning terminal.
The reference station is set by a Real-time kinematic (RTK) technology, the RTK is a difference method for processing carrier phase observed quantities of two measuring stations in Real time, and the carrier phase acquired by the reference station is sent to a user receiver for calculating a difference and a coordinate. The working efficiency can be greatly improved.

The UWB technology is a wireless carrier communication technology, which does not use a sinusoidal carrier, but uses nanosecond-level non-sinusoidal narrow pulses to transmit data, and thus occupies a wide frequency spectrum. The UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception capability, high positioning accuracy and the like, and is particularly suitable for high-speed wireless access in indoor and other dense multipath places.
The positioning terminal is arranged on the safety helmet and/or the employee card, wherein the inertia navigation module is not convenient to install and only the positioning module is installed due to the fact that the size of the employee card is small.
The position information of the operating personnel in the garden can be accurately acquired indoors and outdoors through different positioning methods, the moving track can be generated, and the operating personnel in the garden can be monitored in real time and safely. The state information of the operating personnel is determined by detecting the inclination angle, the acceleration value, the height and the like of the operating personnel, the operating personnel is safely monitored through the moving track of the operating personnel, an alarm can be sent out in time when the operating personnel is in a dangerous state, and the management personnel can conveniently and timely rescue the operating personnel.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a method for monitoring the safety of a park operator according to one or more embodiments of the present disclosure, where the method shown in fig. 1 may include the following steps:
s101: the position information of the operator is obtained through communication among the reference station, the positioning beacon and the positioning module, and the movement track of the operator is generated according to the time sequence of obtaining the position information.
The positioning terminal carried by the operator can be arranged on a safety helmet or an employee card. Taking the safety helmet as an example, a switch is arranged on the safety helmet, and an operator controls the start and stop of the positioning module through operating the switch. The reference station and the positioning beacon can communicate with the positioning module, position information of the operating personnel is obtained in real time, and the position information is connected in series according to the time sequence of the obtained position information to generate a moving track of the operating personnel. It should be noted that, no matter the operator is the person inside the park or the person outside the park, the operator can obtain the position information of the operator through the personnel positioning system as long as the worker wears the safety helmet. The position information is coordinates of a current position of the operator.
S102: and determining the state information of the operating personnel through the navigation information corresponding to the positioning terminal fed back by the inertial navigation module.
In one or more embodiments of the present specification, the navigation information refers to physical information of the positioning terminal in the space generated by the inertial navigation module during navigation, for example, including a tilt angle, an acceleration, and a height. Status information refers to the safety or danger status of a person. For example, if a navigation message is detected to be abnormal, it represents that the person may be in a dangerous state and needs to be rescued.
S103: and monitoring the safety of the operating personnel according to the moving track and/or the state information.
The state information is obtained according to the navigation information, and if the navigation information is abnormal, the personnel may be in a dangerous state.
A plurality of dangerous areas which need permission to enter are arranged in the garden, if a certain operator does not have permission to enter the dangerous areas, the moving track displays that the operator enters the dangerous areas, and the operator is determined to be in a dangerous state.
If a certain operator does not enter the dangerous area, but the acquired movement trajectory of the operator indicates that the operator has moved back and forth a plurality of times on a certain road section, it is determined that the operator is in a dangerous state and the operator may get lost.
In one or more embodiments of the present description, the indoor and outdoor requirements for the strength of the communication signal are different, and if the positioning terminal is located outdoors, the position information of the operator is obtained through the communication between the reference station and the positioning module; if the positioning terminal is located indoors, the position information of the operator is obtained through communication between the positioning beacon and the positioning module; the reference station comprises a carrier phase difference RTK reference station, and the positioning beacon comprises a Bluetooth positioning beacon, an ultra-wideband UWB positioning beacon and a Wi-Fi positioning beacon.
Specifically, the indoor and outdoor requirements for the strength of the communication signal are different, for example, the outdoor space is large, the number of obstacles is small, the space is wide, and the signal obstruction is small, so that the RTK is selected when the position information of the operator is obtained outdoors. When the position information of the operator is acquired outdoors, satellite communication may be used. The indoor space is relatively small, the number of obstacles is large, the signal is blocked strongly, and the situation that the positioning is not accurate or the position information cannot be acquired due to weak signals can be caused when the RTK is used for acquiring the indoor position information of the operator, so that the Bluetooth, the UWB, the WI-FI, the ZigBee and the like are used when the position information of the operator is acquired indoors, in addition, the Radio Frequency Identification (RFID) can be used for carrying out interval-level positioning on the operator, wherein the interval-level positioning refers to the position interval of the operator.
In one or more embodiments of the present disclosure, if only one piece of detected navigation information is abnormal, the false alarm rate is relatively high, for example, the operator leans back slowly on a plane with an inclination angle, at this time, the inclination angle may be relatively large, but the acceleration value is small, and the operator is not in a state of falling backward.
Specifically, the inertial navigation module comprises a gyroscope, an accelerometer and a barometer, wherein the gyroscope can detect the inclination angle of an operator, the accelerometer can detect the acceleration value of the operator, and the barometer can detect the ascending or descending height of the operator.
The normal range of the inclination angle and the acceleration value is stored in the positioning terminal, and the maximum range of the altitude change in the instant time is also stored. If only one of the inclination angle, the acceleration value and the height is abnormal, the operator is considered to be in a safe state, and when at least two detection values are abnormal, the operator is considered to be in a dangerous state.
The positioning terminal is also pre-stored with state information, and when the positioning terminal detects that at least two detection values are abnormal, the state information of the corresponding operator can be determined according to the information types and abnormal degrees of the at least two detection values with the abnormality. The abnormal degree is the difference value of the inclination angle and a standard value, the difference value of the detected acceleration value and a normal acceleration value range, and the difference value of the instantaneous descending height and a normal value. The pre-stored state information is determined according to different information types in the navigation information and the abnormal degree corresponding to each information type, and different state information corresponds to different dangerous states.
The pre-stored state information may only include backward falling, falling slipping, slow falling and the like, but in an actual process, the state information of the operator may have more types, such as backward falling, and in the pre-stored state information, the state information closest to the backward falling is the backward falling, so that the operator is determined to be the backward falling.
Further, a three-dimensional coordinate system is established through an inertial navigation module; if the difference value between the inclination angle between the operator and the Z axis in the three-dimensional coordinate system and the standard value is larger than a first preset angle and the acceleration value is larger than a first preset value, determining that the operator is in a first dangerous state, wherein the inclination angle is determined by the operator along the direction opposite to the facing direction; if the difference value between the inclination angle on any axis in the three-dimensional coordinate system and the standard value is larger than a second preset angle and the acceleration value is larger than a second preset value, determining that the operator is in a second dangerous state, wherein the second preset value is larger than the first preset value; and if the difference value between the inclination angle on any axis in the three-dimensional coordinate system and the standard value is larger than a first preset angle, the acceleration value is larger than a first preset value, and the height is reduced to reach a preset height, determining that the operator is in a third dangerous state.
As shown in fig. 2, the difference between the inclination angle between the operator and the Z axis in the three-dimensional coordinate system and the standard value is greater than 45 degrees, and the acceleration value is greater than the first preset value, so that the operator is determined to fall backward in the first dangerous state. And when the difference value between the inclination angle on any axis in the three-dimensional coordinate system and the standard value is more than 30 degrees and the acceleration value is more than a second preset value, determining that the operator falls and slips under a second dangerous state. And if the difference value between the inclination angle on any axis in the three-dimensional coordinate system and the standard value is more than 30 degrees, the acceleration value is more than a first preset value, and the height is reduced by 0.5 meter, determining that the operator slowly falls down in a third dangerous state. After the dangerous state of the operator is determined, the positioning terminal can send an alarm and position information of the operator to the management terminal, wherein the management terminal is a mobile phone terminal or a computer terminal capable of checking the safety state of the operator.
In one or more embodiments of the present description, the determined hazardous condition may be a false positive. Continuously collecting the change conditions of the inclination angle and the acceleration value; if the change conditions of the inclination angle and the acceleration value are regular changes, replacing the second dangerous state with a first safe state; and if the inclination angle is restored to the range near the standard value within the first preset time and the acceleration value is restored to be smaller than a second preset value within the first preset time, replacing the second dangerous state with a second safe state.
As shown in fig. 3, the difference between the tilt angle and the standard value along any axis in the three-dimensional coordinate system is 30 degrees, and the difference between the tilt angle and the standard value on the same axis is varied back and forth by 30 degrees. Similarly, the acceleration value changes back and forth within a range, and the change situation of the inclination angle and the acceleration value is determined to be regular change. At this time, the second dangerous state is considered as a false alarm, and the second dangerous state is replaced by the first safe state. The first safety state may be triggered by the operator running or working on a platform with a swing law.
Since the inclination angle measured each time may have a corresponding error, the inclination angle is restored to a range near the standard value within the first preset duration, and the acceleration value is restored to be less than the second preset value within the first preset duration, so that the second dangerous state is replaced by the second safe state. The range around the standard value is an interval that is not much different from the standard, for example, when the standard value is 5 degrees, the range around the standard value is 3 degrees to 7 degrees.
The second safety state can be subdivided into two safety states according to the difference of the first preset time length. For example, when the first preset duration is 3 seconds, the inclination angle is changed from the standard value to another angle, the other angle is restored to the range near the standard value, the acceleration value is restored to be smaller than the second preset value, and it is determined that the worker wears or takes off the safety helmet. And when the first preset time is 1 second, determining that the operator collides with the object.
The above description is only given by way of example of the first dangerous state, the second dangerous state, the third dangerous state, the first safe state, and the second safe state, and the first dangerous state, the second dangerous state, the third dangerous state, the first safe state, and the second safe state are not only the above states.
In one or more embodiments of the present specification, a plurality of areas are divided in a garden, and electronic fences are previously installed in some areas in the garden; and in the area corresponding to the electronic fence, determining that the navigation information and/or the position information of the operator do not change within a second preset time period, and sending an alarm through the positioning terminal.
The plurality of areas divided in the garden comprise rest areas, operation areas and the like, partial areas for setting the electronic fence can be the rest areas and can also be the operation areas, if the areas corresponding to the electronic fence are the rest areas, the changes of the inclination angle, the acceleration and the height are not detected within a second preset time, and the coordinates of the operator are not changed, at the moment, the operator possibly sleeps or is dangerous in the rest areas, and an alarm is sent through the positioning terminal. If the area that the fence corresponds is the operation area to in second preset duration, not detect inclination, acceleration, change of height, and operating personnel's coordinate also does not change, at this moment, this operating personnel probably has taken place danger because of the operation, sends out the warning through positioning terminal, so that managers in time to its rescue. It should be noted that the second preset duration corresponding to the rest area is longer than the second preset duration corresponding to the working area.
In one or more embodiments of the present specification, a plurality of areas are divided in a campus, and a part of the areas in the campus is divided into dangerous areas in advance; determining a coordinate set corresponding to the dangerous area when the operating personnel in the dangerous area has higher operating danger, and determining a coordinate subset corresponding to an entrance and an exit of the dangerous area in the coordinate set; judging whether the corresponding coordinates of the operator in the moving process are in the coordinate set; if not, determining that the closest distance between the coordinate and each coordinate in the coordinate subset is smaller than the preset distance, and gradually reducing the closest distance in the moving process; and determining that the operator is in the fourth dangerous state.
Since the operator must pass through the entrance/exit of the dangerous area, it is possible to determine whether the operator will enter a dangerous state by determining the closest distance between the operator and the entrance/exit of the dangerous area and the trend of the change in the closest distance. And determining a coordinate subset corresponding to the entrance and the exit of the dangerous area, determining the closest distance between the corresponding coordinate of the operator in the moving process and each coordinate in the coordinate subset, and judging the closest distance between the operator and the entrance and the exit of the dangerous area. The corresponding coordinates of the operator during the movement are changed, and the closest distance of the operator to the entrance of the dangerous area is also changed. The gradual reduction of the nearest distance not only means that the distance is reduced every moment, but also means that the overall trend is gradually reduced. The fourth dangerous state refers to a state in which the worker is about to enter a dangerous area.
In one or more embodiments of the present description, a historical movement track of the operator is determined, the historical movement track of the operator is stored in the positioning system, it is determined that the operator has arrived at the dangerous area according to the historical movement track, and a similarity between the historical movement track and a movement track corresponding to the movement process is higher than a preset threshold.
For example, when the similarity between the movement trajectory corresponding to the current movement process of the operator and the historical movement trajectory reaching the dangerous area is higher than eighty percent, the operator is likely to enter the dangerous area.
In one or more embodiments of the present description, a plurality of management areas are divided in advance among a plurality of areas divided in a campus, and for each management area, a staff allocation upper limit corresponding to the management area is determined, the staff allocation upper limit being the maximum number of workers that can be accommodated in the management area without hindering safety management and work progress. Determining the number of personnel in the management area according to the position information corresponding to each operator; and if the number of the personnel exceeds the personnel configuration upper limit, sending a prompt to at least part of the operators in the management area through the positioning terminal so as to realize personnel scheduling. The method is favorable for guaranteeing the operation safety of each management area.
In one or more embodiments of the present disclosure, the campus is divided into a plurality of types, and toxic gas may be leaked from a dangerous area in a relatively dangerous campus such as a chemical industry campus. The air safety condition of the environment where the operator is located is detected through the gas probe arranged on the safety helmet, and the operator is prompted when toxic gas is detected. The harm to the health of the operators caused by the fact that the operators are in the environment full of toxic gas for a long time is avoided.
