Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.

The embodiment of the invention provides a blasting misoperation prevention system 1, wherein the blasting misoperation prevention system 1 is used for monitoring a blasting process so as to reduce or avoid misoperation in the blasting process and improve the safety of blasting. The blasting error prevention system 1 comprises a positioning system 100, an alert zone 200 and an error prevention device 300 connected with the positioning system 100, wherein:
the positioning system 100 includes a plurality of positioning devices 110, and the positioning system 100 is configured to position the positioning devices 110 and the initiation point of the area to be blasted, and when the initiation point is positioned, specifically, the position of the initiation point is positioned by one positioning device in the positioning system 100, so as to accurately obtain the position of the initiation point. The positioning device 110 can use an existing positioning system to perform positioning, for example, a GPS positioning system, a beidou positioning system, etc., and the positioning device 110 may be a dedicated positioning terminal or a communication terminal with a positioning function (for example, a mobile phone with a positioning function). Optionally, in another embodiment of the present invention, the positioning system 100 further includes a base station, and the base station is connected to the anti-error device and all the positioning devices to realize positioning of the positioning devices and the explosion point. In the present invention, the positioning system may adopt a positioning system that is mature or feasible through theoretical research in the prior art, and the embodiment provides only one positioning system, and the connection between the error prevention device and the base station can be regarded as the communication connection between the error prevention device and the positioning system. If the base station is not needed in other positioning systems, the anti-misoperation device directly establishes communication connection with the positioning terminal, and can also be regarded as the communication connection with the positioning system to acquire the position of the positioning terminal. The invention is not limited to the positioning system and the connection mode between the positioning system and the anti-riot host.
The alert zone 200 is defined as a zone formed by spreading a set distance around the initiation point, and the zone (i.e., alert zone) is considered a dangerous zone where people or things located in the zone are vulnerable to the blast during the blast, and is typically a circular zone around the initiation point, but may be other suitable zones, for example, a circular zone around 300 meters as defined in the industry.
The anti-misoperation device 300 is connected with the positioning system 100 to acquire the position of a detonation point and monitor the positions of all positioning devices in the positioning system 100 and alarm signals sent by the positioning devices, and the anti-misoperation device 300 is also connected with a detonation circuit to control the disconnection or connection of the detonation circuit. If the anti-error device 300 monitors that any positioning device is located in the warning area 200 or receives an alarm signal of any positioning device, the initiation line is controlled to be disconnected so as to prohibit initiation.
In the embodiment of the invention, the blasting anti-misoperation system comprises a positioning system, anti-misoperation devices and a warning area, wherein the positioning system comprises a plurality of positioning devices, the anti-misoperation devices monitor the positions of all the positioning devices and alarm signals sent by all the positioning devices, and if the anti-misoperation devices monitor that any one of the positioning devices is positioned in the warning area or receives the alarm signal of any one of the positioning devices, the anti-misoperation devices control the detonation circuit to be disconnected so as to prohibit the detonation, thereby realizing the key processes in the blasting process and the effective monitoring of related positioning device users and other personnel, and reducing the occurrence rate of blasting accidents.
In an embodiment of the present invention, as shown in fig. 2, the anti-error device 300 may include an anti-error host 320 and an initiation controller 330, the anti-error host 320 is connected to the positioning system 10 and monitors positions of all positioning devices and alarm signals sent by all positioning devices, the initiation controller 330 is connected to the initiation line and connected to the anti-error host 320, and is controlled by the anti-error host 320 to control disconnection or connection of the initiation line, and if the anti-error host 320 monitors that any positioning device is located in an alert area or receives an alarm signal of any positioning device, the initiation controller is controlled to be disconnected to control disconnection of the initiation line, so as to prohibit initiation and achieve explosion anti-error.
In this embodiment, the detonation controller 330 is connected to the detonation circuit of the detonation capsule, and controls the detonation circuit to be disconnected in an initial state. For the convenience of understanding, the initiation controller 330 may be an electronic switch controlled by the error prevention host 320 and connected in series to the initiation line, so as to control the on/off of the initiation line, and the initiation signal may be sent only when the initiation line is connected. In order to ensure safety, the detonation controller controls the detonation circuit to be disconnected in the initial state, so that the anti-error host 320 does not perform any operation on the current state of the detonation controller 330 under the condition that the detonation condition is not met, and the anti-error host can be regarded as controlling the detonation controller to be disconnected.
In another embodiment of the present invention, the blasting error prevention system 1 may further include a decision device, the decision device sends an instruction of allowing initiation to the error prevention device 300 when receiving an instruction of allowing initiation from a user of the decision device, if the error prevention device 300 does not receive the instruction of allowing initiation from the decision device, the detonation circuit is controlled to be disconnected to prohibit initiation, and if the error prevention device 300 monitors that the plurality of positioning devices are located outside the alert area, does not receive the alarm signals of the plurality of positioning devices, and receives the instruction of allowing initiation from the decision device, the detonation circuit is controlled to be connected to allow initiation. Therefore, only when all the positioning devices of the anti-error blasting system are located outside the warning area, the anti-error blasting system does not receive the alarm signal of any positioning device, and the anti-error blasting system receives the allowable detonation instruction of the decision device, the anti-error blasting system controls the detonation circuit to be communicated so as to allow detonation, and therefore the anti-error effect of the anti-error blasting system is improved.
Illustratively, a blast fool-proofing system as shown in fig. 2 includes a positioning system 100, an alert zone 200, and a fool-proofing device 300. The positioning system 100 includes a plurality of positioning devices 110 and a base station 120, and the positioning of the positioning devices 110 is realized by the base station 120, and the positioning devices 110 can be carried by a security officer (positioning device user) to position the security officer when the security officer visits an alert zone 200, and the alert zone 200 is set as an area formed by spreading a security distance around a detonation point 220. The error prevention device 300 monitors the positions of all the positioning devices 110 and the sent alarm signals, and if the error prevention device 300 monitors that the positioning devices are located in the warning area 200 or receives the alarm signals of the positioning devices, the initiation circuit is controlled to be disconnected to prohibit initiation. Here, as an example, the error preventing device 300 includes an error preventing host 320 and an initiation controller 330 (e.g., a programmable control switch), where the error preventing host 320 monitors the positions of all the positioning devices and the alarm signals sent by the positioning devices, and if the error preventing host 320 monitors that the positioning devices are located in the warning area 200 or receives the alarm signals of the positioning devices, the initiation controller 330 is controlled to be disconnected to control the initiation line to be disconnected, so as to prohibit initiation and achieve explosion error prevention. The blasting anti-error system further comprises a decision device 400, and when receiving an initiation allowing instruction from a decision device user, the decision device 400 sends the initiation allowing instruction to the anti-error device 300, where the decision device user may specifically be a general command or project principal in the blasting site. The anti-misoperation device 300 controls the detonation circuit to be connected through the detonation controller only when monitoring that all the positioning devices are located outside the warning area, do not receive the alarm signal of any positioning device and receive the detonation permission instruction of the decision device, so as to allow detonation, and controls the detonation circuit to be disconnected if the anti-misoperation device 300 does not receive the detonation permission instruction of the decision device, so as to prohibit detonation, thereby improving the anti-misoperation effect of the anti-misoperation system for blasting. When the anti-misoperation device 300 controls the connection of the detonation circuit through the detonation controller, although detonation is allowed, the detonation can be performed only after a detonation instruction is sent by a blaster through the detonator 340, so that the safety of blasting is further improved.

in step S301, a positioning system including a plurality of positioning devices is constructed, and an error prevention device that controls the initiation line to be turned on or off is constructed.
The embodiment of the invention is suitable for a blasting anti-misoperation system to monitor blasting operation executed in a blasting process, and particularly the blasting anti-misoperation system comprises a positioning system, a warning area and an anti-misoperation device connected with the positioning system, wherein the positioning system comprises a plurality of positioning devices used for positioning the positioning devices and a blasting point of an area to be blasted, and the positioning devices are carried by a security guard (positioning device user). The positioning device can utilize the existing positioning system to perform positioning, for example, a GPS positioning system, a beidou positioning system, etc., and the positioning device can be a dedicated positioning terminal or a communication terminal with a positioning function (for example, a mobile phone with a positioning function). Optionally, in another embodiment of the present invention, the constructing of the positioning system further includes providing a base station, the base station is connected to the positioning device to realize positioning of the positioning device and the initiation point, and the error prevention device is in communication connection with the base station to obtain a positioning signal of the positioning device.
The constructed anti-misoperation device monitors the positions of all the positioning devices and the alarm signals sent by the positioning devices, and if the anti-misoperation device monitors that the positioning devices are located in a warning area or receives the alarm signals of the positioning devices, the initiation circuit is controlled to be disconnected so as to inhibit initiation. When the anti-error device is constructed, the anti-error device can comprise an anti-error host and an initiation controller, the anti-error host can be a tablet computer, a notebook computer or a desktop computer, the anti-error host is in communication connection with a base station and is used for monitoring the position of the positioning device and an alarm signal sent by the positioning device, if the anti-error host monitors that any positioning device is located in a warning area or receives the alarm signal of any positioning device, the initiation controller is controlled to be disconnected, so that the initiation circuit is controlled to be disconnected, initiation is forbidden, and anti-error blasting is realized. The detonation controller can be a programmable control switch, the programmable control switch is connected with the error prevention host and the detonation circuit, and the programmable control switch is used for receiving a control command sent by the error prevention host to control the detonation circuit to be connected or disconnected.
In step S302, the position of the detonation point is located by a positioning device of the plurality of positioning devices, and a region formed by spreading a set distance around the detonation point is set as a warning region.
In the embodiment of the present invention, the alert zone is set to be a zone formed by spreading a set distance around the initiation point, and the zone (i.e., alert zone) is considered to be a dangerous zone where people or objects located in the zone are easily damaged by the explosion during the explosion, and the alert zone is usually a circular zone around the initiation point, but may be other suitable zones, for example, the alert zone may be a circular zone with a radius of 300 meters set by the industry. After the range of the warning area is determined, a virtual electronic fence can be specifically defined by the error prevention host to define the warning area so as to monitor the position of the positioning device subsequently.

Example three:
fig. 4 shows an implementation flow of a blasting error prevention method provided by a third embodiment of the present invention, and for convenience of description, only the parts related to the third embodiment of the present invention are shown, which are detailed as follows:
in step S401, the positioning device acquires the position information of the detonation point, and transmits the position information of the detonation point to the error prevention device.
The embodiment of the invention is suitable for a blasting anti-error system, which comprises a positioning system, a warning area and an anti-error device, and specifically, the blasting anti-error system shown in embodiment 1 and fig. 1 can be referred to. When the positioning device acquires the position information of the detonation point, the positioning device carried by a user (a security officer) through the positioning device can position the detonation point to obtain the position information of the detonation point, specifically, the user carries the corresponding positioning device to reach a specified target area of the detonation point, finds the accurate detonation point in the target area of the detonation point, and positions the detonation point through the positioning device to obtain the accurate position information of the detonation point, and sends the accurate position information to the error prevention device, thereby quickly and accurately acquiring the position information of the detonation point.
Preferably, in another embodiment of the present invention, when the positioning device obtains the location information of the initiation point, the error prevention device obtains the initial locations of all the positioning devices, determines the positioning device closest to the initial location of the initiation point according to the initial locations of all the positioning devices and the input initial location of the initiation point (such as the name of the initiation point or the target area of the initiation point), the error prevention host sends a positioning instruction for positioning the initiation point to the user of the positioning device closest to the initial location of the initiation point, when the user of the positioning device closest to the initial location of the initiation point receives the positioning instruction, the user of the positioning device carries the corresponding positioning device to reach the specified target area of the initiation point, searches for the accurate initiation point in the target area of the initiation point, positions the initiation point through the positioning device, and sends the position confirmation information of the accurate initiation point to the error prevention device, when the anti-misoperation device receives the position confirmation information returned by the positioning device closest to the initial position of the detonation point, the current position of the positioning device is set to be the position of the detonation point by the anti-misoperation device, so that the positioning efficiency of the detonation point is improved while the positioning accuracy of the detonation point is improved.
Preferably, in another preferred embodiment, when the error prevention device obtains the position information of the initiation point through the positioning device, the error prevention device also obtains the blasting parameter information of the initiation point and the surrounding environment information of the initiation point, so as to confirm whether the blasting parameter of the initiation point and the surrounding environment of the initiation point meet the preset initiation point requirement, thereby improving the safety and success rate of subsequent blasting, wherein the blasting parameter information may include the drilling parameter, the charging parameter and the like of the initiation point, and the surrounding environment information of the initiation point may include the geological condition information of the initiation point. Specifically, a positioning device user can shoot an image of a current detonation point through a camera arranged in the positioning device or other communication terminals carried by the positioning device, the shot image is sent to an anti-error device through the positioning device (namely a positioning system) or other communication terminals, the anti-error device identifies the image after receiving the image shot by the positioning device user so as to obtain drilling parameters, charging parameters and the like of the detonation point, optionally, the positioning device user can also manually input the data into the positioning device or other communication terminals after measuring the related data of the detonation point, and then the data is sent to the anti-error device through the positioning device or other communication terminals so as to obtain the blasting parameter information of the detonation point and the surrounding environment information of the detonation point.
In step S402, when the error prevention device receives the position information of the detonation point, the error prevention device sets a warning area of the detonation point according to the position information of the detonation point, and monitors the position information and the warning information of all the positioning devices.
In the embodiment of the invention, after the error preventing device receives the position information of the detonation point, the error preventing device sets the warning area range of the detonation point by taking the position of the detonation point as the center, if the industry sets that 300 meters is a blasting danger distance, the warning area range is set as the warning area range by taking the detonation point (namely the position of the explosive setting point) as the center of a circle and diffusing a distance of at least 300 meters outwards, so that the setting accuracy of the warning area range is improved.
Preferably, in another preferred embodiment, if the error preventing device further receives the initiation point blasting parameter information and the initiation point surrounding environment information from the positioning device, the received initiation point blasting parameter information and the initiation point surrounding environment information are matched with the initiation point blasting parameter information and the initiation point surrounding environment information stored in the error preventing device in advance, if the initiation point blasting parameter information and the initiation point surrounding environment information are not consistent, a confirmation request of the initiation point blasting parameter information and the initiation point surrounding environment information is sent to the positioning device, so that a positioning device user confirms the initiation point blasting parameter information and the initiation point surrounding environment information, and only if the error preventing device is confirmed to be consistent in matching, the warning area range of the initiation point is set according to the position information of the initiation point, thereby improving the accuracy of setting the warning area range.
In the embodiment of the invention, after the error preventing device sets the warning zone range of the detonation point according to the position information of the detonation point, all positioning device users carry out danger investigation (for example, investigation on the existence of other people in the warning zone) in the warning zone range. In a preferred embodiment, when all the users of the positioning device check other persons within the range of the warning area (i.e. users of non-positioning devices), specifically, the user of the current positioning device can detect whether there are other users of the positioning device or other persons mistakenly entering the range of the warning area in the surrounding environment through the human infrared sensor of the positioning device, and when the user of the current positioning device detects that there are other users of the positioning device or other persons mistakenly entering the range of the warning area, the user of the current positioning device can send out a warning signal through a speaker or a flashlight, and can timely remind other persons within the range of the warning area or other users of the positioning device to leave, thereby ensuring that all the persons within the range of the warning area have left the range of the warning area.
In the embodiment of the present invention, when monitoring the position information and the alarm information of all the positioning devices, preferably, the positioning device monitors the communication between the positioning device and the anti-error device, and when it is monitored that the communication between the positioning device and the anti-error device is abnormal (for example, network delay, large fluctuation of communication signals, etc.), the positioning device sends communication abnormality alarm information to the anti-error device to process the communication abnormality of the positioning device in time, so as to ensure the safety of blasting.
In the embodiment of the present invention, when monitoring the position information and the alarm information of all the positioning devices, it is further preferable that the positioning devices monitor heart rate or pulse of users of the positioning devices, and when monitoring that the heart rate or pulse of users of the positioning devices is abnormal, the positioning devices send terminal abnormality alarm information to the error prevention device, so as to timely process the terminal abnormality of the positioning devices (for example, to eliminate whether the positioning devices are lost), thereby ensuring safety of blasting.
In step S403, when the current position of any one of the positioning devices is located in the warning area or receives the alarm information of any one of the positioning devices, the detonation circuit is controlled to be disconnected to prohibit the detonation.
In the embodiment of the invention, when the current position of any positioning device is positioned in the warning area or receives the alarm signal of any positioning device, the error prevention device controls the detonation circuit to be disconnected through the detonation controller, and the detonation is forbidden, so that the safety of the detonation is improved.
In another embodiment of the invention, if the anti-error blasting system further comprises a decision device, the decision device sends an instruction of allowing detonation to the anti-error blasting system when receiving an instruction of allowing detonation of a user of the decision device, and the anti-error blasting system controls the detonation circuit to be communicated only when monitoring that all the positioning devices are located outside the warning area, do not receive the alarm signal of the positioning devices, and receive the instruction of allowing detonation of the decision device, so as to allow detonation, thereby improving the anti-error effect of the anti-error blasting system. The anti-misoperation device sends an allowable blasting instruction to the detonation controller, so that the anti-misoperation device controls the detonation controller to connect the detonation circuit, the detonator does not directly detonate, and the detonator also needs field operators to detonate through the detonator so as to further ensure the blasting safety.
As an example, as shown in fig. 5a, 5b, 5c and 5d, fig. 5a shows a case where one positioning device (positioning 1) is currently within the alert zone, at which time the anti-error device controls the initiation line to be disconnected to disable the initiation, fig. 5b shows a case where all the positioning devices are located outside the alert zone, but one positioning device is monitored to send alarm information (positioning 1 in fig. 5b sends an SOS signal), at which time the anti-error device controls the initiation line to be disconnected to disable the initiation, fig. 5c shows a case where all the positioning devices are located outside the alert zone, and none of the positioning devices sends alarm information to the anti-error device, but the anti-error device does not receive the initiation permission signal of the decision terminal, at which time the control initiation line is disconnected, and still the initiation is disabled, fig. 5d shows a case where all the positioning devices are located outside the alert zone, and no positioning device sends alarm information to the anti-misoperation device, and the anti-misoperation device receives a detonation permission signal of the decision terminal, so that the current situation can be considered to meet the condition that the anti-misoperation device sends a blasting permission instruction to the detonation controller. In the embodiment of the invention, when all the positioning terminals are monitored to be located outside the warning area and the positioning terminals are still monitored to be kept outside the warning area within a preset time period (for example, 3 minutes), the position information of the positioning terminals can be ensured to be in a stable state, misjudgment possibly caused by communication signal delay is avoided, and when any one of the positioning terminals does not send alarm information to the anti-error host and receives a detonation permission signal of the decision terminal, the anti-error host sends a blasting permission instruction to the programmable controller, so that the safety of subsequent blasting is improved.
In other preferred embodiments, the anti-riot host can also send the alert zone range to all the positioning terminals so that the positioning terminals know their own positions, and reminding devices, such as indicator lights (or speakers), can be arranged on the positioning terminals in response to the positions of the positioning terminals. When the positioning terminal identifies that the positioning terminal is positioned in the warning area, a red indicator light (or voice prompt) is used for indicating that the positioning terminal is positioned in the warning area; when the positioning terminal is positioned outside the warning area, a green indicator light (or voice prompt) is used for indicating that the positioning terminal is positioned outside the warning area. Of course, in other embodiments, the error prevention host may not send the warning area range to the positioning terminal but only monitor the position information of the positioning terminal, and may control the reminding device on the positioning terminal by sending an instruction to the positioning terminal; when the positioning terminal identifies that the positioning terminal is located in the warning area, the positioning terminal is controlled to indicate that the positioning terminal is located in the warning area through a red indicator lamp; when the positioning terminal is located outside the warning area, the positioning terminal is indicated to be located outside the warning area by a green indicating lamp.
In the embodiment of the invention, the warning area range of the initiation point is set according to the position information of the initiation point, the position information and the warning information of all the positioning devices are monitored, and when the current position of any one positioning device is positioned in the warning area or receives the warning signal of any one positioning device, the initiation line is controlled to be disconnected so as to inhibit initiation, so that the early warning and initiation key processes in the outdoor blasting process, the positions of positioning device users and the like are effectively monitored, and the occurrence rate of blasting accidents is reduced.
