Detailed Description

As shown in fig. 1 and 2, the invention discloses a comprehensive online safety monitoring and early warning system for an open pit, which comprises:
(1) The detection module is arranged on the strip mine and used for generating slope detection information, parking space detection information and environment detection information. For different monitoring objects and areas, the detection module can comprise a plurality of detection devices arranged at corresponding positions, such as a GNSS receiver R30 type slope detection device for monitoring a slope, a radar receiver and other slope detection devices for monitoring the position of a person, a GPS receiving device for monitoring the position of a person vehicle, a wireless sensor network detection node system and other temperature detection devices for a coal field fire area, a wireless rainfall sensor QS1501 and other rainfall detection devices, an LD-5 multi-parameter dust sensor and other dust concentration detection devices. Those skilled in the art will appreciate that the above disclosed detection apparatus is not exhaustive. Each detection device can generate detection signals (electric signals) when detecting, and the electric signals can be classified into side slope detection information, personal parking position detection information and environment detection information according to categories.
(2) The network module is electrically connected with the detection module and is used for uploading the slope detection information, the man-vehicle position detection information and the environment detection information to the cloud service platform. Preferably, a network module for uploading can be arranged in the strip mine, and the network module is respectively connected with each detection device of the detection module in a wireless communication mode and is used for receiving each generated detection information and intensively uploading the detection information to the cloud service platform through a 4G mobile network, a GPRS network and the like; in another mode, each detection device of the detection module is respectively and independently connected with a network module, the network modules are relatively independent, and the detection signals generated by the detection devices are directly uploaded through the corresponding network modules.
(3) The cloud service platform is used for respectively determining corresponding slope parameter information, person parking space parameter information and environment parameter information based on the slope detection information, the person parking space detection information and the environment detection information, namely, converting signals generated by the detection module into identifiable specific parameters. Preferably, the cloud service platform can adopt the existing hundred-degree cloud, the existing Arin cloud, the existing Tech cloud and the like, has the capability of data processing and storage, reduces the requirement of a system on local operation hardware by applying the mature cloud service platform, and saves the implementation cost.
(4) The safety monitoring and early warning platform can respectively judge whether the slope parameter information, the parking lot position parameter information and the environment parameter information reach corresponding early warning thresholds. The early warning threshold value can be predetermined and stored in the safety monitoring early warning platform. The safety monitoring and early warning platform can be connected with the cloud service platform through the Internet, and the cloud service platform is called to process the obtained slope parameter information, the personal vehicle position parameter information and the environment parameter information. If at least one of the slope parameter information, the person vehicle position parameter information and the environment parameter information reaches the corresponding early warning threshold value, an alarm is sent, wherein the slope parameter information, the person vehicle position parameter information and the environment parameter information can comprise specific parameters of a plurality of items, for example, the items included in the environment parameter information are as follows: temperature parameters, rainfall parameters, dust concentration parameters and the like of fire areas and other areas in the strip mine are respectively corresponding to respective early warning thresholds, when specific parameters of any item reach the corresponding early warning thresholds, namely the parameter information reaches the corresponding early warning thresholds, the condition that safety risks are possible/exist is indicated, people need to be treated or evacuated in time, and specific item types and detection equipment (such as sensors) can be determined based on actual requirements and are not listed one by one.
Preferably, different comparison judgment rules can be adopted for different parameter information, and the judgment rules and corresponding early warning thresholds can be predetermined and stored in the safety monitoring early warning platform. The safety monitoring and early warning platform comprises a processor and a memory which can adopt the existing model to realize the processing and the storage of data/information. The invention can present any alarm mode, such as flashing warning lamp, sounding buzzer, etc.
In some embodiments of the present invention, the system further includes a time synchronization module, configured to perform time synchronization on the detection module, and set the same acquisition frequency, so as to ensure that the acquisition of the slope parameter information, the parking space parameter information, and the environmental parameter information come from the same time, avoid errors caused by data asynchronization, and enhance comprehensive early warning capability. Preferably, the time synchronization can be performed on each detection device based on the TPSN protocol, and the same acquisition interval is set, so that each detection device can realize synchronous acquisition of data.
In some embodiments of the present invention, the safety monitoring and early warning platform is specifically configured to determine specific parameters of each item in the slope parameter information, the person position parameter information, and the environment parameter information.
And respectively judging whether the slope speed parameter, the slope acceleration parameter and the slope displacement parameter contained in the slope parameter information reach the corresponding slope early warning threshold value or not.
And respectively judging whether the temperature parameter, the rainfall parameter and the dust concentration parameter contained in the environmental parameter information reach the corresponding environmental early warning threshold value or not. The specific number of the three parameters can be multiple, and the three parameters are respectively used for reflecting the temperature, the rainfall and the dust concentration of each area in the strip mine, for example, a fire area wireless sensor network monitoring node with the temperature of-130-1000 ℃ and the height of Wen Meitian can be arranged in the fire area of the strip mine so as to monitor the temperature of the fire area.
For the personnel and vehicle position parameter information, personnel and vehicle positioning equipment can be placed on personnel or vehicles to detect positions, position coordinate parameters, personnel and vehicle speed parameters and safety distance parameters are acquired based on acquired coordinates, time and coordinates of a predetermined dangerous area, and judgment is carried out: whether the vehicle speed pre-warning threshold value is within a dangerous position range threshold value, whether the vehicle speed pre-warning threshold value is reached, and whether a safe distance threshold value is reached.
Further, the judgment mode of the parking lot location parameter information is as follows:
firstly, determining the position of a man-vehicle area based on position coordinate parameters; then, the speed early warning threshold value and the safety distance threshold value corresponding to the position of the area of the man-car are obtained, and the speed early warning threshold value and the safety distance threshold value corresponding to the position of different areas are different, so that the position of the area where the detection equipment (such as a GPS receiver and the like) is located needs to be determined firstly, and then the speed early warning threshold value and the safety distance threshold value corresponding to the position of the area are determined; and finally, judging whether the speed parameter of the person reaches the speed early warning threshold value or not, and judging whether the safety distance parameter reaches the safety distance threshold value or not.
In some embodiments of the present invention, as the state of each area in the strip mine changes, in addition to considering the characteristics of each area, the safety monitoring and early warning platform may also call a matched early warning threshold based on the current state of the area, specifically, may determine the area where a person or a vehicle is located and the slope parameter information and/or the environmental parameter information corresponding to the area, including but not limited to, when the parameter of a certain item in the area exceeds the early warning threshold, determine that the state of the area is a normal/dangerous state, and then select to call a corresponding early warning threshold according to the normal/dangerous state of the area, and compare with the above-mentioned person position parameter information. For example, the safety monitoring and early warning platform judges that the rainfall parameter of the strip mine exceeds the corresponding early warning threshold value through data processing (the acquisition of parameter information and the judgment of the early warning threshold value are detailed above), the road surface of the area where the vehicle is located is slippery, in order to ensure the running safety, when the vehicle runs in the area, the vehicle should keep a lower speed relative to the rain-free state, the safety monitoring and early warning platform respectively stores two vehicle speed early warning threshold values corresponding to two different states that the current area where the vehicle is in the rain-free state and the rainfall exceeds the early warning threshold value, and the safety monitoring and early warning platform calls the matched vehicle speed early warning threshold value according to the actual state of the area. Further, for pre-storing and selecting the early warning threshold value, a plurality of project parameters reflecting the state of the area where the person and vehicle are located can be referred to, for example, the situation that the safety situation of the vehicle is possibly affected by too high flying dust concentration and large rain amount is considered, so that the rainfall parameter and the flying dust concentration parameter in the environment parameter information are required to be referred to simultaneously for the person and vehicle speed early warning threshold value of the area where the vehicle is located, all the possible situations of the two parameter information are preset in the safety monitoring early warning platform, and in actual monitoring, the safety monitoring platform can determine the state of the area based on the acquired parameter information and select and call the early warning threshold value corresponding to the state of the area to carry out comparison and judgment. Of course, there are some situations that the difference of certain or certain states of the area where the people and vehicles are located does not affect the safety of the people and vehicles, so that a plurality of early warning thresholds do not need to be preset. And because the time synchronization and the acquisition frequency between the detection devices are the same, the accurate synchronization between the parameter information is ensured, and the operation reliability of calling the early warning threshold value based on the state of the area where the person and the vehicle are located is increased.
In some embodiments of the present invention, in order to more timely remind personnel in a dangerous area and avoid information delay caused by manual operation, the present invention may also provide an alarm module for prompting relevant personnel to evacuate and evacuate in a manner of sound, light, etc. only in the corresponding area of each detection device of the strip mine. The safety monitoring and early warning platform is further used for: determining and prompting the corresponding position area of the slope parameter information/the parking space parameter information/the environment parameter information in the strip mine, wherein the slope parameter information/the parking space parameter information/the environment parameter information reach the early warning threshold value; and sending alarm information/instructions to alarm modules corresponding to the position areas, and sending an alarm according to the alarm information/instructions.
