Detailed description of the invention:
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
Fig. 1 gives downhole intelligent security system function schematic diagram of the present invention.The present invention utilizes technology of Internet of things, intelligent sensing and mode identification technology to develop the wearable security system of underground coal mine intelligent personal.This system is made up of three parts: wearable personal information harvester, the underground communication system with two redundancy feature and personal information processing center.Wearable personal information harvester, is mainly used in relevant information and the CO such as personnel in the pit's vital sign parameter, motion state, the Acquire and process of the ambient parameters such as CH4, O2, and provides the communication of non-real time voice in emergency circumstances.This system adopts modularized design, and wherein respiration transducer, core signal sensor, environmental parameter sensor etc. can as apolegamy modules.The underground communication system of two redundancy feature is on the network architecture basis that down-hole Ethernet is trunk, support the open Internet of things system of different first isomeric data agreement based on heterogeneous network element Internet of things system model construction, realize in emergency circumstances intelligence that is wired, wireless mode by intelligent network state detecting and switch the reconstruction with hybrid network link.The information that personal information processing center gathers wearable personal information apparatus is analyzed, processes and is stored, and carries out warning reminding time necessary.
Fig. 2 gives ambient parameter acquisition module block diagram.At present, the distributed capture of mine gas environment and warning system relative maturity, the mode generally by installing fixed checkout gear and manual inspection in relevant position, down-hole realizes the parameter acquisition of subsurface environment.But once there is emergency, fixed checkout equipment often due to down-hole power-off, or causes thrashing owing to destroying, and manual inspection is also difficult to carry out.Now for down-hole distress personnel, necessary collection can be carried out to the key parameter of environment, and current risk factor is analyzed, assess and early warning, be necessary.The gas sensor of low cost is adopted to realize the isoparametric collection of CO, CH4, O2 of distress personnel place environment, treatment and analyses is carried out by setting up the various data of subsurface environment risk assessment model to ambient parameter, obtain the assessment of subsurface environment risk factor, when ambient parameter arrives harmful grade, system can send warning message from trend command centre and point out miner to take corresponding measure by the mode such as LED or buzzer.
Fig. 3 gives non-real time voice communication system block diagram.Non-real time voice communication system mainly realizes the voice communication of in emergency circumstances aboveground commanding and down-hole trapped personnel.Because down-hole line transmission system after mine disaster generation mostly can be in paralyzed state, it is available that network is difficult to guarantee, and therefore native system is selected to carry out transferring voice communication signal by wireless sensor network.Because the bandwidth of wireless sense network is very limited, especially in case of emergency there is bulk redundancy bandwidth and be difficult to be effectively guaranteed in network, and therefore we adopt non real-time voice communication system.It is by being embedded in miniature Mike on miners' cap wall and the earphone voice messaging important and brief to personnel gathers, and is then stored in TF card by Information Compression packing, carries out non real-time communication by wireless sensor network and the external world.In addition, by designing artificial alarm button, in order in particular cases underground work personnel to command centre's manual alarm.
Fig. 4 gives personal safety system entire block diagram.Whole intelligent safety system mainly comprises part of data acquisition and network portion.Part of data acquisition comprises the collection of ambient parameter, the collection of human body physiological parameter, the collection of voice messaging.Wherein environment information acquisition is directly read by UART, single bus interface primarily of STM32 controller; Human Physiology information, by independent processor collection, sends STM32 controller to by bluetooth; Voice messaging is directly read by STM32 controller application SPI interface, and data are directly stored in TF card.All information is sent to Zigbee network by UART interface after integrating on STM32, information enters Ethernet by Zigbee network, aboveground this locality has client to monitor data, and information can also be sent to long-distance user by the webserver, as long as user over ethernet just can check the situation of downhole rescuing personnel by corresponding Authority Verification.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
