Referring to fig. 2, an embodiment of the invention discloses an intelligent ground wire safety control method. The implementation body of the method may be the above-mentioned intelligent grounding wire 130, or an intelligent grounding wire safety control device installed on the intelligent grounding wire 130, which is not limited in the present invention. The method comprises the following steps 210-270:
210. when the intelligent grounding wire is monitored to be used, the intelligent grounding wire is controlled to be bound with the handheld terminal.
In the embodiment of the invention, the intelligent grounding wire can be provided with the inertial sensor, so that the attitude change of the intelligent grounding wire can be periodically monitored. Specifically, inertial sensing data acquired by an inertial sensor on the intelligent grounding wire can be periodically acquired, the inertial sensing data of each period are identified, and when the intelligent grounding wire is identified to be changed from a static state to a moving state from the inertial sensing data acquired in the current period, the intelligent grounding wire is judged to be taken.
Or in other possible embodiments, when the intelligent grounding wire is identified to be changed from the static state to the moving state from the inertial sensing data acquired in the current period, the identification judgment can be also performed by combining the inertial sensing data acquired in the previous period. That is, if the inertial sensing data collected in the current period identifies that the intelligent grounding wire is changed from the stationary state to the moving state, and the inertial sensing data collected in the previous period of the current period identifies that the intelligent grounding wire is kept in the stationary state, the intelligent grounding wire is judged to be taken. Therefore, the intelligent grounding wire is subjected to gesture recognition by fusing the inertial sensing data of the two acquisition periods, and the recognition accuracy can be improved.
Further, the intelligent grounding wire is used for outputting verification request information when the intelligent grounding wire is judged to be taken, and the verification request information is used for acquiring an authorization permission instruction of the handheld terminal; and the handheld terminal is used for outputting an authorization permission instruction to the intelligent ground wire safety management and control device when receiving the verification request information. Then, the intelligent ground wire safety control device binds with the handheld terminal according to the authorized permission instruction.
The handheld terminal comprises, but is not limited to, mobile terminals such as mobile phones, tablet computers and interphones, and is generally carried by users (such as operators), an application program is built in the handheld terminal, an operation ticket can be received on site through a 4G private network, wireless communication with an intelligent grounding wire is supported, and functions such as real-time transmission of state data and command issuing are achieved.
As an alternative implementation manner, the storage cabinet may be provided with an electronic lock electrically connected with the distribution network scheduling device 110, and a reader is arranged in the electronic lock, so that the electronic lock can perform wireless radio frequency short-distance communication with a radio frequency card held by a user, and has the characteristics of non-contact, high reading speed, no abrasion and the like. In practical application, the reader sends a radio frequency signal with a certain frequency through the transmitting antenna, when the radio frequency card enters the working area of the transmitting antenna, an induction current is generated, and the radio frequency card obtains energy to be activated; the radio frequency card sends out information such as self-coding and the like through a built-in transmitting antenna of the card; the receiving antenna of the reader receives the carrier signal sent from the radio frequency card, and the carrier signal is transmitted to the reader through the antenna regulator, the reader demodulates and decodes the received signal to obtain user identity information, and then the user identity information is sent to the distribution network scheduling device 110 for relevant processing. Specifically, the distribution network scheduling device 110 judges whether the user identity information belongs to the trusted identity information, and if so, controls the electronic lock of the storage cabinet to be opened; if not, the electronic lock of the control storage cabinet is kept closed.
Further, the storage cabinet can be further provided with an electronic display screen, the electronic display screen is electrically connected with the distribution network scheduling device 110, after the distribution network scheduling device 110 controls the electronic lock of the storage cabinet to be opened, the distribution network scheduling device 110 can further acquire an operation ticket corresponding to the user identity information, according to the content of the operation ticket, an intelligent grounding wire meeting the operation requirement is determined from a plurality of intelligent grounding wires of the storage cabinet to serve as a target intelligent grounding wire, and the number of the target intelligent grounding wire is output to the electronic display screen so as to prompt a user to take the target intelligent grounding wire. According to the content of the operation ticket, a target intelligent grounding wire meeting the operation requirement is determined from a plurality of intelligent grounding wires of the storage cabinet, and in a specific implementation mode, a destination of an operation site is determined according to the content of the operation ticket, a route duration between the destination and the storage cabinet is calculated, and then required electric quantity is determined according to the route duration, wherein the route duration and the required electric quantity form a positive correlation relation, namely, the larger the route duration is, the more the required electric quantity is. And then, the intelligent grounding wire with the residual electric quantity larger than the required electric quantity is selected from a plurality of intelligent grounding wires of the storage cabinet to serve as a target intelligent grounding wire meeting the operation requirement.
Wherein the target intelligent ground line may include one or more. Firstly, the number of the grounding wires required by a user can be determined according to the content of the operation ticket, and then the target intelligent grounding wires are selected according to the number. For example, if the number of the grounding wires required by the user is one, and the selected intelligent grounding wires with the residual electric quantity larger than the required electric quantity are multiple, any one of the intelligent grounding wires can be selected, or one of the intelligent grounding wires with the maximum residual electric quantity can be selected; if the number of the grounding wires required by the user is N (N is more than 1), and the number of the selected intelligent grounding wires with the residual electric quantity larger than the required electric quantity is more than one, N intelligent grounding wires with larger residual electric quantity can be selected.
220. And acquiring the satellite positioning signal strength perceived by the intelligent grounding wire at a specified frequency.
In the embodiment of the invention, after the intelligent grounding wire is monitored to be taken, the built-in positioning instrument is started to search for satellites at the designated frequency, or in order to save power consumption, the built-in positioning instrument is started to search for satellites at the designated frequency after the intelligent grounding wire is controlled to be bound with the handheld terminal, so that satellite positioning signals are acquired through a satellite positioning system (such as a GPS system or a Beidou satellite navigation system) and the strength of the satellite positioning signals is perceived.
The satellite positioning system is a satellite system consisting of a plurality of satellites covering the whole world, and can provide real-time, all-weather and global navigation services. The three parts are as follows: constellation, ground monitoring system, signal receiver. The user receives satellite signals through the signal receiver, and obtains the information of the user position, the speed and the like through signal processing, so that the purposes of navigation and positioning by using a satellite positioning system are realized. The GPS system comprises 24 satellites, and the Beidou satellite navigation system comprises 39 satellites. Since satellite positioning signals come from satellites in the sky, the troposphere, ionosphere, and tall ground buildings of the atmosphere all affect the signal reception by the signal receiver. Such as: in a building, it is likely that a search for a star cannot be completed and the current location cannot be discerned.
In the application scene of the invention, the intelligent grounding wire is generally placed in a storage cabinet of a power distribution network warehouse when not in use, the power distribution network warehouse is generally built in a building construction area, however, a satellite positioning system cannot sense satellite signals due to dense building construction, so that accurate positioning cannot be performed. That is, the satellite positioning signal strength perceived by the intelligent ground wire in an indoor environment is generally less than the satellite positioning signal strength perceived by the intelligent ground wire in an outdoor environment. In order to identify when the intelligent grounding wire is taken out from the indoor environment to the outdoor environment after the storage cabinet is taken out, a preset threshold value can be set, and the condition that the intelligent grounding wire is taken out from the indoor environment to the outdoor environment can be judged.
230. If the satellite positioning signal strength of the intelligent grounding wire in the taken preset time period is changed from being smaller than the preset threshold value to reaching the preset threshold value, and the first duration time when the satellite positioning signal strength reaches the preset threshold value reaches the first preset duration time, judging that the intelligent grounding wire is discharged from the indoor environment to the outdoor environment.
It should be noted that the preset threshold value may be a critical value for indicating that the satellite positioning signal strength is sufficient for accurate positioning and insufficient for accurate positioning, and the critical value may be a value obtained and preset by a developer according to actual conditions or experimental data. When the satellite positioning signal strength reaches (i.e. is greater than or equal to) the critical value, the satellite positioning is regarded as accurate satellite positioning; when the satellite positioning strength is smaller than the critical value, the satellite positioning result error is considered to be larger. Therefore, after the intelligent ground wire is taken, if the perceived satellite positioning signal strength in the preset time period is changed from being smaller than the preset threshold value to reaching the preset threshold value and maintaining the first preset time period, the intelligent ground wire is judged to be discharged from the indoor environment to the outdoor environment.
240. When the intelligent grounding wire is in an outdoor environment, a first satellite positioning result and first air pressure data of the handheld terminal are obtained at a preset frequency.
In the embodiment of the invention, the handheld terminal is internally provided with the air pressure sensing device, the first air pressure data can be the atmospheric pressure in the ambient air where the handheld terminal is positioned, and the air pressure sensing device can be a barometer for measuring the atmospheric pressure, and the types of the air pressure sensing device include a mercury barometer and a non-liquid barometer. It will be appreciated that at different levels, the atmospheric pressure will also vary. Therefore, the horizontal height of the position of the user can be determined through the atmospheric pressure, and the smaller the atmospheric pressure is, the larger the horizontal height of the position of the user is, otherwise, the larger the atmospheric pressure is, the smaller the horizontal height of the position of the user is.
250. And determining the three-dimensional electronic fence where the handheld terminal is positioned according to the first satellite positioning result and the first air pressure data.
Firstly, according to a first satellite positioning result and first air pressure data, three-dimensional positioning is performed on a handheld terminal, and according to preset parameters of a preset electronic fence, such as shape, specification and size, a three-dimensional electronic fence (also called a three-dimensional electronic fence) is constructed in a three-dimensional space.
260. And determining the outdoor position of the intelligent grounding wire according to the second satellite positioning result of the intelligent grounding wire and the second air pressure data.
Similarly, the intelligent grounding wire can be internally provided with an air pressure sensing device, and the second air pressure data can be the atmospheric pressure in the ambient air where the intelligent grounding wire is located. And the first satellite positioning result and the second satellite positioning result both refer to positioning results comprising longitude and latitude information.
The first satellite positioning result and the first air pressure data of the handheld terminal are updated at a preset frequency, and similarly, the three-dimensional electronic fence constructed based on the first satellite positioning result and the first air pressure data is updated at the preset frequency. And after each three-dimensional electronic fence update, judging whether the second satellite positioning result and the second air pressure data of the intelligent grounding wire exceed the three-dimensional electronic fence or not. It should be noted that, the three-dimensional electronic fence is dynamically updated in real time, and is updated in real time along with the change of the position of the handheld terminal.
270. If the outdoor position is shifted from the three-dimensional electronic fence to the outside of the three-dimensional electronic fence, and the second duration outside the three-dimensional electronic fence reaches the second preset duration, sending alarm prompt information to the handheld terminal.
The alarm prompt information at least comprises distance information and azimuth information of the intelligent grounding wire relative to the handheld terminal. As an optional implementation manner, after sending the alarm prompt information to the handheld terminal, the built-in speaker can be controlled to send out a sound signal in a preset sounding mode; and/or controlling the LED luminous plate arranged outside to emit light signals in a preset color and/or a preset flicker frequency; and/or controlling the intelligent grounding wire to send out a vibration signal at a preset vibration frequency.
Through the implementation mode, the early warning prompt is carried out from one or more aspects of hearing, vision and touch, and multi-dimensional sound, light and mechanical early warning prompt can be realized, so that when a user of the handheld terminal bound with the intelligent grounding wire does not receive alarm prompt information in time, the intelligent grounding wire can send out early warning prompt in situ, the attention of other people who pass can be brought to, and the possibility that the intelligent grounding wire is found is increased.
As another alternative implementation manner, after sending the alarm prompt information to the handheld terminal, if the user of the handheld terminal bound to the intelligent grounding wire does not receive the alarm prompt information in time, the intelligent grounding wire can also be in communication connection with other terminal devices through other ways so as to draw attention of the user of the other terminal devices, and the possibility that the intelligent grounding wire is found is increased. Specifically, bluetooth communication with nearby terminal devices is attempted by activating the bluetooth function. For example, the following steps 271 to 274, not shown, may be performed:
271. if the response information sent by the bound handheld terminal aiming at the alarm prompt information is not received within the appointed duration, starting the Bluetooth function of the intelligent grounding wire, and searching terminal equipment for starting the Bluetooth function within the Bluetooth signal coverage range of the intelligent grounding wire.
272. And modifying the Bluetooth user name of the intelligent grounding wire into a preset user name.
The preset user name may include ground wire loss information, so that the success rate of the bluetooth connection request may be increased.
273. And initiating a Bluetooth connection request to the terminal equipment through a preset user name.
274. And when the Bluetooth connection is successful, transmitting user contact information and alarm prompt information of the handheld terminal to the terminal equipment through the Bluetooth connection.
The user contact information and the alarm prompt information of the handheld terminal are sent to the terminal equipment, and the alarm prompt information can be transmitted to the user of the handheld terminal through the user contact information by means of the user of the terminal equipment.
Therefore, by implementing the embodiment, the position relationship between the intelligent grounding wire and the operator can be tracked, namely whether the intelligent grounding wire follows the vicinity of the handheld terminal or not can be tracked, and an alarm is given when the intelligent grounding wire is far away from the handheld terminal, so that the operator can conveniently know about a lost event in time and search for the lost event, and the intelligent degree of the intelligent grounding wire is improved. In addition, can also fuse atmospheric pressure data and carry out three-dimensional stereotactic to improve intelligent earth connection's location accuracy.
Example two
The embodiment of the invention also considers that when the intelligent grounding wire enters indoor environments such as a storehouse and the like, the indoor position of the intelligent grounding wire is difficult to track by utilizing the satellite positioning system in real time, so that the position change of the intelligent grounding wire in the storehouse cannot be tracked in time. However, when the operator returns the intelligent ground wire to the warehouse, the intelligent ground wire may not be returned to the storage cabinet of the warehouse due to human errors, but may be scattered at other positions in the warehouse, and even the situation that a specific intelligent ground wire cannot be found in the warehouse may occur. Therefore, referring to fig. 3, another method for controlling safety of an intelligent ground wire is disclosed in the embodiment of the present invention. The method comprises the following steps 310-380:
310-320. Steps 310 to 320 refer to the detailed descriptions of steps 210 to 220 in the first embodiment, and the present invention will not be described in detail.
330. If the satellite positioning signal strength is changed from reaching the preset threshold value to being smaller than the preset threshold value, and the third duration time that the satellite positioning signal strength is smaller than the preset threshold value reaches the third preset duration time, judging that the intelligent grounding wire enters the indoor environment from the outdoor environment.
340. And determining the current moment when the satellite positioning signal strength is converted from reaching a preset threshold value to being smaller than the preset threshold value as the conversion moment.
Since the transition of the satellite positioning signal strength from reaching the preset threshold to being less than the preset threshold can be regarded as a transition process, the last time before the transition when the satellite positioning signal strength has reached the preset threshold, or the first time after the transition when the satellite positioning signal strength is less than the preset threshold can be determined as the transition time.
350. Determining a third satellite positioning result of the intelligent grounding wire at a historical moment; wherein the history time precedes the transition time, and the history time differs from the transition time by a specified period of time.
The history time can be obtained by advancing a specified time period based on the transition time. At the historical moment, the satellite positioning signal strength perceived by the intelligent ground wire still reaches a preset threshold value, so that satellite positioning can be performed.
