Description

Technical Field

[0001] The present invention relates to the technical field of police equipment, and in particular to a police shoulder light with fusion positioning. Background Art

[0002] Police shoulder lights are used by police officers while on duty, typically mounted on the shoulder of their uniforms to enhance their visibility and identification. Conventional police shoulder lights consist of a power control module and an LED driver module, and are limited in functionality. Beyond basic warning and lighting functions, most lack positioning capabilities and are unable to provide location information for the officer wearing them. However, in actual operations, police command centers require the precise location of officers wearing them and the distribution of on-duty officers within their jurisdiction to rapidly respond to emergencies, dispatch resources, and direct operations.

[0003] The addition of a positioning module increases the power consumption of police shoulder lights, but the battery capacity of these lights is relatively small, resulting in poor battery life and the inability to operate continuously for extended periods. In some cases, officers may even experience a situation where their shoulder lights are unable to operate due to insufficient power while on duty. Furthermore, existing police shoulder lights with positioning functions lack intelligent control over their operating modes, making it impossible to extend the operating time, reduce the number of recharges, and increase the service life of the lights while maintaining the same battery capacity. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a police shoulder light with integrated positioning, which includes a control method for intelligently controlling the working mode of the police shoulder light through the positioning function, so as to solve the problem that the working time of the police shoulder light cannot be extended and the number of charging times cannot be reduced when the battery capacity of the existing police shoulder light remains unchanged.

[0005] A police shoulder light with integrated positioning includes a power supply, a light module, a positioning module, and a controller electrically and / or communicatively connected to the positioning module, the light module, and the power supply. The power supply supplies power to the light module, the positioning module, and the controller. The controller controls the operation of the light module by the following method:

[0006] Obtaining a current position signal of the police shoulder light, and determining the current duty sub-area where the police shoulder light is located based on the position signal and the pre-stored boundaries of each duty sub-area;

[0007] Obtain the historical police situation alarm frequency ratio of the duty sub-area, and control the working mode of the light group module according to the relationship between the historical police situation alarm frequency ratio and the alarm frequency ratio threshold;

[0008] The working modes of the light group module include control of light on / off, light flashing, flashing frequency and light brightness.

[0009] Compared with the existing technology, the police shoulder light with integrated positioning of the present invention obtains the position signal of the police shoulder light in real time through the positioning module, determines the duty sub-area where the police shoulder light is located according to the pre-stored boundaries of each duty sub-area, and obtains the historical proportion of police dispatch times in the duty sub-area, and controls the working mode of the light group module according to the relationship between the historical proportion of police dispatch times and the threshold of the proportion of police dispatch times, thereby effectively reducing the energy consumption of the light group, realizing intelligent control of the use of the police shoulder light to extend the working time of the police shoulder light, reduce the number of charging times and improve the service life of the police shoulder light.

[0010] Furthermore, the relationship between the historical police incident response frequency ratio and the response frequency ratio threshold specifically includes:

[0011] If the historical alarm response times ratio is greater than or equal to the first alarm response times ratio threshold, the historical alarm response levels of the duty sub-area are traversed, and the working mode of the light group module is controlled according to whether there is a high-risk alarm and the ratio of high-risk alarms:

[0012] If the historical alarm response times ratio is less than the first alarm response times ratio threshold and greater than or equal to the second alarm response times ratio threshold, the historical alarm response times of the duty sub-area are traversed, and the working mode of the light group module is controlled according to whether there is a high-risk alarm situation:

[0013] If the proportion of historical police calls is less than the second police call threshold, the working mode of the light group module is controlled according to the lighting conditions of the duty sub-area;

[0014] Among them, the first police dispatch frequency ratio threshold is greater than the second police dispatch frequency ratio threshold.

[0015] Furthermore, if the historical alarm response times are greater than or equal to the alarm response times threshold, the controller controls the working mode of the light group module in the following manner:

[0016] Traverse the historical police alert levels of the duty sub-area to determine whether there is a high-risk alert:

[0017] If yes, further calculate the proportion of high-risk alarms:

[0018] If the proportion of high-risk alarms is greater than or equal to a high-risk warning threshold, the controller controls the working mode of the light group module to be: intermittent flashing of red and blue lights, the flashing frequency is the maximum frequency, and the brightness is high brightness;

[0019] If the proportion of high-risk alarms is less than the high-risk warning threshold, the controller controls the working mode of the light group module to: intermittent flashing of red and blue lights, high flashing frequency, and medium brightness;

[0020] If not, further determine whether there is a low-risk alarm:

[0021] If there is a low-risk alarm, the controller controls the working mode of the light group module to be: the red and blue lights flash intermittently, the flashing frequency is medium frequency, and the brightness is medium brightness;

[0022] If there is no low-risk alarm, the controller controls the working mode of the light group module to be: the red and blue lights are always on and the brightness is medium.

[0023] Furthermore, if the historical alarm response times ratio is less than the first alarm response times ratio threshold and greater than or equal to the second alarm response times ratio threshold, the controller controls the working mode of the light group module in the following manner:

[0024] Traverse the historical police alert levels of the duty sub-area to determine whether there is a high-risk alert:

[0025] If yes, the controller controls the working mode of the light group module to be: intermittent flashing of red and blue lights, high flashing frequency, and medium brightness;

[0026] If not, further determine whether there is a low-risk alarm:

[0027] If there is a low-risk alarm, the controller controls the working mode of the light group module to be: the red and blue lights flash intermittently, the flashing frequency is medium frequency, and the brightness is medium brightness;

[0028] If there is no low-risk alarm, the controller controls the working mode of the light group module to be: the red and blue lights are always on and the brightness is medium.

[0029] Furthermore, if the historical alarm response times ratio is less than the second alarm response times ratio threshold, the controller controls the working mode of the light group module in the following manner:

[0030] Get the lighting conditions of the duty sub-area:

[0031] If the lighting condition is good, the controller controls the light group module to turn off the light;

[0032] If the lighting conditions are poor, the controller controls the working mode of the light group module to be: single flash of red light or single flash of blue light, medium flashing frequency, and medium brightness.

[0033] Furthermore, the police shoulder light further includes a photoelectric sensor. If the proportion of historical police response times is less than the second police response times ratio threshold, the controller controls the working mode of the light group module in the following manner:

[0034] Get the light intensity signal of the current environment where the police shoulder light is located:

[0035] If the light intensity signal is greater than or equal to a light intensity threshold, the controller controls the light group module to turn off the light;

[0036] If the light intensity signal is less than the light intensity threshold, the controller controls the working mode of the light group module to: single flash of red light or single flash of blue light, medium flashing frequency, and medium brightness.

[0037] Furthermore, the police shoulder light also includes a transmission interface module, which transmits the real-time position signal of the police shoulder light to the police command center. When receiving the dispatch instruction sent by the police command center, the controller also controls the light group module according to the following method:

[0038] Get new police dispatch instructions sent by the police command center:

[0039] If a new police situation occurs in the duty sub-area where the police shoulder light is located, the controller controls the working mode of the light group module to be: the red light is always on and the brightness is medium;

[0040] If a new police situation occurs outside the duty sub-area where the police shoulder light is located, the controller controls the working mode of the light group module to be: the blue light is always on and the brightness is medium.

[0041] Furthermore, the duty sub-area where the police shoulder light is currently located is determined by the following method:

[0042] Get the current position signal of the police shoulder light including the latitude of the police shoulder light Lat t and longitude Lon t ;

[0043] Get the boundaries of each duty sub-area, which is defined by the longitude and latitude coordinates of the boundary vertices of the polygonal area, that is, duty sub-area A i Expressed as:

[0044] A i :[P i1 (Lat i1 ,Lon i1 ),...,P im (Lat im ,Lon im ),...P in (Lat in ,Lon in )],m∈(1,n)

[0045] Among them, P im represents the mth boundary vertex of the ith duty sub-area, Lat im , Lon im Corresponding to the boundary vertex P im latitude and longitude;

[0046] From the current latitude of the police shoulder light Latt and longitude Lon t The determined position point emits a ray in any direction and calculates the distance between the ray and each duty sub-area A i The number of intersection points of each region edge:

[0047] If the number of intersections is odd, then the current position of the police shoulder light is in the duty sub-area A. i Inside;

[0048] If the number of intersections is even, then the current position of the police shoulder light is not in the duty sub-area A. i outside.

[0053] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention.

[0054] To address the problem of existing police shoulder lights with positioning functions suffering from poor battery life due to small battery capacity, which affects police officers' use while on duty and reduces their warning effectiveness, the present invention proposes a police shoulder light with fusion positioning. This police shoulder light includes a control method based on fusion positioning. This control method controls the driving and combined lighting modes of the police shoulder light based on the historical police situation in the area to which the real-time positioning location of the police shoulder light belongs. This intelligent and rational control of the police shoulder light's usage extends its operating time, reduces the number of charging cycles, and increases its service life.

[0055] For specific implementation, please refer to Figure 1 The police shoulder light with integrated positioning proposed in this invention includes a power supply, a light assembly module, a positioning module, and a controller. The power supply supplies power to the light assembly module, the positioning module, and the controller. The positioning module obtains the location of the police shoulder light and transmits the location signal to the controller. The controller generates a light control signal based on the historical police situation, lighting conditions, or environmental conditions corresponding to the location information. The light assembly module controls the light on and off, flashing mode, and brightness according to the light control signal transmitted by the controller.

[0056] The light module consists of an array of LED lights with adjustable brightness, providing red and blue strobe and white light illumination. Specifically, the red and blue strobe operating modes include: single red flash, solid red, single blue flash, solid blue, intermittent red and blue flashing, and solid red and blue. The strobe flash frequency is 8.3Hz, and the operating current during flashing is ≤45mA; the operating current during white light illumination is ≤35mA.

[0057] The positioning module includes an outdoor positioning unit and an indoor positioning unit.

[0058] The outdoor positioning unit is a single Beidou dual-frequency RTK positioning module that integrates Beidou ground-based enhanced high-precision positioning technology, and is used to receive signals from the Beidou system's L1 and L5 frequency bands to obtain the outdoor position signal of the police shoulder light when it is outdoors.

[0059] The indoor positioning unit is a positioning module that integrates WIFI hotspot and base station positioning technology, and is used to obtain the position signal of the police shoulder light when it is indoors. The 4G positioning chip of the base station positioning technology, or the 5G positioning chip using multiple positioning technologies such as multi-RTT, UL-AoA and DL-AoD can be used. This application is not limited as long as it can receive the surrounding base station signals in an indoor environment to complete the indoor positioning of the police shoulder light and send the indoor position signal.

[0060] The controller includes a storage unit and a processing unit.

[0061] The storage unit is used to store and update the historical police situation and alarm level of each duty sub-area in the duty area, as well as the lighting situation and monitoring layout situation in the duty sub-area.

[0062] The processing unit is used to obtain the position signal of the police shoulder light; determine whether the position corresponding to the position signal belongs to the duty sub-area of the duty area; and call the historical police situation, police level, lighting conditions, and monitoring layout of the corresponding duty sub-area in the storage unit, and comprehensively determine the required working mode of the shoulder light based on the above conditions, control the power supply to supply power to the light group module and control the operation of the light group module.

[0063] Furthermore, the police shoulder light also includes a photoelectric sensor, which senses the light intensity of the environment in which the police shoulder light is located and transmits the light intensity signal to the controller. The controller adjusts the current output by the power supply to the light group module according to the light intensity signal and thereby controls the intensity of the light group module.

[0064] Furthermore, the police shoulder light also includes a transmission interface module, which is used to provide a data transmission link between the police shoulder light and external devices. Specifically, it provides a data transmission link between the police shoulder light and the police command center, transmits the police shoulder light's real-time location signal to the police command center, and receives dispatch instructions from the police command center. Correspondingly, the controller's processing unit is also used to control the operation of the light module based on the dispatch instructions received from the police command center.

[0065] See also Figure 2 The control method of the police shoulder light corresponding to the above-mentioned police shoulder light with fusion positioning includes the following steps.

[0066] S10 obtains the current position signal Q of the police shoulder light t , according to the position signal Q t and the boundaries of each pre-stored duty sub-area to determine the duty sub-area A where the police shoulder light is located at the current moment i .

[0067] In specific implementation, the current position signal Q of the police shoulder light t Including the latitude of police shoulder lights t and longitude Lon t , that is, Q t (Lat t ,Lon t ). For outdoor use using satellite positioning, obtain the position signal Q based on the satellite positioning information t Latitude t and longitude Lon t For indoor positioning technologies such as 4G positioning chips, 5G positioning chips, WiFi hotspot positioning, Bluetooth beacon positioning, and UWB positioning, the acquired position signal Q t According to the corresponding indoor positioning technology, the coordinate point-longitude and latitude conversion algorithm is converted into Q t Corresponding latitude Lat t and longitude Lon t , all of the above indoor positioning technologies can be used and this application does not impose any restrictions.

[0068] The i-th duty sub-area A i The boundary of the polygonal area is defined by the longitude and latitude coordinates of the boundary vertices, that is, the duty sub-area A i Expressed as:

[0069] A i :[P i1 (Lat i1 ,Lon i1 ),...,P im (Lat im ,Lon im),...P in (Lat in ,Lon in )],m∈(1,n)

[0070] Among them, P im represents the mth boundary vertex of the ith duty sub-area, Lat im , Lon im Corresponding to the boundary vertex P im latitude and longitude.

[0071] Use the ray method to determine the duty sub-area A where the police shoulder light is located at the current moment i Specifically, from the current latitude of the police shoulder light Lat t and longitude Lon t Determined position point Q t Send a ray in any direction and calculate the distance between the ray and each duty sub-area A i If the number of intersections is an odd number, then the current position of the police shoulder light is in the duty sub-area A. i If the number of intersections is even, then the current position of the police shoulder light is not in the duty sub-area A. i outside.

[0072] In another embodiment, a geographic information system (GIS) is used to obtain the latitude Lat of the police shoulder light at the current moment. t and longitude Lon t , quickly determine whether the current position of the police shoulder light belongs to the predetermined duty sub-area A i .

[0073] S20 obtains the duty sub-area A where the police shoulder light is located at the current moment i The proportion of historical police dispatch times p i :

[0074] If the number of police calls in history accounts for p i Greater than or equal to the first police response ratio threshold Right now Then execute step S30;

[0075] If the number of police calls in history accounts for p i Less than the first police response ratio threshold And greater than or equal to the second police response ratio threshold Then execute step S40;

[0076] If the number of police calls in history accounts for p i Less than the second alarm response ratio threshold Right now Then execute step S50.

[0077] In specific implementation, the duty sub-area A i The proportion of historical police dispatch times p i For the duty sub-area A i The percentage of the number of police calls due to police incidents in a certain period of time to the total number of police calls due to police incidents in the entire duty area A in a certain period of time, that is, p i satisfy:

[0078]

[0079] Among them, n i Represents the i-th duty sub-area A i The number of police calls due to police incidents within a certain period of time, N A Indicates the total number of police dispatches due to police incidents in the entire duty area A within a certain period of time.

[0080] The first police dispatch rate ratio threshold Greater than the second alarm response ratio threshold Right now The first police dispatch rate ratio threshold and the second threshold of the proportion of police calls All of them are obtained through modeling and analysis of historical police data.

[0081] S30 traverses the duty sub-area A i The level of historical police incidents can be used to determine whether there are high-risk incidents:

[0082] If yes, then further calculate the proportion of high-risk alarms R i :

[0083] For example, the proportion of high-risk police incidents R i Greater than or equal to the high-risk warning threshold R target , that is, R i ≥R target , the controller controls the working mode of the light group module to be: intermittent flashing of red and blue lights, the flashing frequency is the maximum frequency, and the brightness is high brightness;

[0084] For example, the proportion of high-risk police incidents R i Less than the high-risk warning threshold R target , that is, R i <R target , the controller controls the working mode of the light group module to be: intermittent flashing of red and blue lights, high flashing frequency, and medium brightness;

[0085] If not, further determine whether there is a low-risk alarm:

[0086] If there is a low-risk alarm, the controller controls the working mode of the light group module to be: the red and blue lights flash intermittently, the flashing frequency is medium frequency, and the brightness is medium brightness;

[0087] If there is no low-risk alarm, the controller controls the working mode of the light group module to be: the red and blue lights are always on and the brightness is medium.

[0088] In practice, the police response levels include: Level 1 (L1), which refers to criminal incidents exceeding 50% of the normal rate, or prominent public security issues, such as terrorist attacks and major violent incidents; Level 2 (L2), which refers to emergencies involving the safety of life and property of the public, such as theft, robbery, and other crimes; Level 3 (L3), which involves the interests of the general public and may trigger large-scale emergencies, such as family disputes and traffic accidents; and Level 4 (L4), which involves the interests of the general public, such as trivial public security incidents. Level 1 (L1) and Level 2 (L2) are uniformly categorized as high-risk incidents, Level 3 (L3) as low-risk incidents, and Level 4 (L4) as general incidents.

[0089] The proportion of high-risk police incidents is R i satisfy:

[0090]

[0091] Among them, n L1 Represents the i-th duty sub-area A i The number of police dispatches due to level 1 police incidents within a certain period of time, n L2 Represents the i-th duty sub-area A i The number of police calls due to secondary police incidents within a certain period of time, the nth i Represents the i-th duty sub-area A i The number of police dispatches due to police incidents within a certain period of time.

[0092] S40 traverses the duty sub-area A i The level of historical police incidents can be used to determine whether there are high-risk incidents:

[0093] If yes, the controller controls the working mode of the light group module to be: intermittent flashing of red and blue lights, high flashing frequency, and medium brightness;

[0094] If not, further determine whether there is a low-risk alarm:

[0095] If there is a low-risk alarm, the controller controls the working mode of the light group module to be: the red and blue lights flash intermittently, the flashing frequency is medium frequency, and the brightness is medium brightness;

[0096] If there is no low-risk alarm, the controller controls the working mode of the light group module to be: the red and blue lights are always on and the brightness is medium.

[0097] S50 Obtain duty sub-area A i Lighting conditions:

[0098] If the lighting condition is good, the controller controls the light group module to turn off the light;

[0099] If the lighting conditions are poor, the controller controls the working mode of the light group module to be: single flash of red light or single flash of blue light, medium flashing frequency, and medium brightness.

[0100] Furthermore, when the police shoulder light is provided with a photoelectric sensor, step S50 may be step S50'.

[0101] S50` obtains the light intensity signal of the environment where the police shoulder light is located at the current moment:

[0102] If the light intensity signal is greater than or equal to a light intensity threshold, the controller controls the light group module to turn off the light;

[0103] If the light intensity signal is less than the light intensity threshold, the controller controls the working mode of the light group module to: single flash of red light or single flash of blue light, medium flashing frequency, and medium brightness.

[0104] Furthermore, when the police shoulder light is provided with a transmission interface module that can transmit the real-time position signal of the police shoulder light to the police command center and receive the dispatch instruction sent by the police command center, the controller also controls the light group module according to the following method:

[0105] SA1 obtains new police dispatch instructions from the police command center:

[0106] If the new police situation occurs in the duty sub-area A where the police shoulder light is located i Inside, the controller controls the working mode of the light group module to be: the red light is always on, and the brightness is medium brightness;

[0107] If the new police situation occurs in the duty sub-area A where the police shoulder light is located i In addition, the controller controls the working mode of the light group module as follows: the blue light is always on and the brightness is medium.

[0108] This control method allows the police command center to inform police officers whether there is an emergency in the surrounding area by lighting up the police shoulder lights.

[0109] The police shoulder light control method based on fusion positioning of the present invention obtains the position signal of the police shoulder light in real time, determines the duty sub-area where the police shoulder light is located according to the pre-stored boundaries of each duty sub-area, and obtains the historical proportion of the number of police calls in the duty sub-area. The working mode of the light group module is controlled according to the historical proportion of the number of police calls in the duty sub-area, thereby effectively reducing the energy consumption of the light group and realizing intelligent control of the use of the police shoulder light to extend the working time of the police shoulder light, reduce the number of charging times and improve the service life of the police shoulder light.
