The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
Fig. 1 is a schematic diagram of an application scenario in an embodiment of the present invention. In the application scenario, a plurality of positioning base stations, WiFi devices, ranging devices and the like are arranged in the tunnel, the devices transmit information to an on-site monitoring room outside the tunnel through a network, and the on-site monitoring room is communicated with an engineering command department/a remote management center through the network. In this application scenario, the "tunnel face" is the tunnel location where collapse accidents occur most easily.
In the common tunnel collapse accident, the buried constructors are generally in a passive rescue state, and the search and rescue personnel can only gradually probe on the collapse ruins by using a probe similar to a life detector. The invention provides an electronic tag for seeking help for tunnel personnel, and a device and a system for rescuing the tunnel personnel by applying the electronic tag. Before the collapse accident appears in the tunnel construction, in daily excavation production activity, let tunnel constructor wear the electronic tags of this application in advance, for example let tunnel personnel dress etc. through placing the electronic tags of this application in tunnel personnel's safety helmet, in intelligent bracelet (or intelligent wrist-watch etc.). After the tunnel collapse accident occurs, the tunnel personnel rescue devices can be actively connected with an external life detection instrument, and relevant information of tunnel personnel is transmitted to the life detection instrument, so that the situation that the tunnel personnel can only passively wait for the appearance of the rescue personnel is changed.
As shown in fig. 2, a schematic structural diagram of an electronic tag for help seeking of tunnel personnel in an embodiment is shown. The electronic tag for help seeking of tunnel personnel in the embodiment mainly comprises a positioning circuit module and a help seeking circuit module. In another embodiment, the electronic tag for help seeking of tunnel personnel further comprises a detection circuit module, a power supply module and the like.
It should be understood by those skilled in the art that the division of the circuit blocks in the present application is only a division of logical functions, and the actual implementation may be fully or partially integrated into one or more physical entities. For example, the help-seeking circuit module may be a chip element which is set up separately, or may be integrated in a certain chip; the positioning circuit module can be an independent GPS module, a Beidou module and the like, and can also be integrated in a certain chip for realization; other circuit blocks are implemented similarly.
The positioning circuit module is used for positioning the real-time position of the tunnel personnel and dynamically positioning the tunnel personnel. Referring to fig. 3, after a collapse accident occurs, the distress circuit module is used for establishing communication connection with the life detection instrument and establishing an ad hoc network with other surrounding electronic tags for distress call of tunnel personnel, so that the position information and the identification information of the electronic tags for distress call of all tunnel personnel are sent to the life detection instrument. The detection circuit module is used for detecting the vital sign information of the tunnel personnel. The power module is used for supplying power to the SOS circuit module, the positioning module and the detection module.
In one embodiment, the distress circuit module periodically sends out a communication signal for searching the life detection instrument. For example, to save electricity, the distress circuit module sends out a communication signal every 5 minutes, and the communication signal is a transparent transmission signal. When the distress circuit module does not receive the response signal of the life detection instrument, the distress circuit module keeps the power saving mode of the life detection instrument searched in the current period; and starting a distress mode when receiving the response signal of the life detection instrument, and actively establishing communication connection with the life detection instrument in the distress mode. In detail, when tunnel collapse does not occur, the distress circuit module does not receive the response of the life detection instrument because the life detection instrument does not exist at the periphery, and at the moment, the distress circuit module continues to work in the power saving mode. Once the tunnel collapse accident happens, rescue workers can conduct rescue work, the probes of the life detection instruments are inserted into the collapsed time-delay fragments and clods, and contact signals of the buried tunnel workers are searched and approached to the greatest extent. The life detection instrument immediately sends a response signal when detecting the contact signal sent by the distress circuit module, and at the moment, the life detection instrument and the electronic tag establish 'handshaking' and communication connection.
In an embodiment, the distress circuit module transmits the response signal to the surrounding other electronic tags for distress call of the tunnel personnel, so as to enable the surrounding other electronic tags for distress call of the tunnel personnel to start a distress mode, thereby forming an ad hoc network.
In detail, the response signal of the life detector can activate the distress circuit module of the electronic tag, and the distress circuit module is converted from the power saving mode to the distress mode after being activated. The help-seeking circuit module entering the help-seeking mode continuously searches for other peripheral electronic tags and transmits the response signal to the other peripheral electronic tags, so that the help-seeking circuit modules of the other electronic tags are activated, and the help-seeking circuit modules of the other electronic tags are converted into the help-seeking mode from the power-saving mode. And (4) trying to automatically form a network with the nearest electronic tag by each electronic tag in the help-seeking mode, and finally forming a transparent transmission network between the electronic tags.
The life detection instrument receives each electronic tags's identification information (like ID number), positional information, vital sign information, and statistics is buried tunnel personnel's quantity and vital sign, according to the power of every electronic tags "shake hands" signal, further judges buried tunnel personnel's accurate position, with current rescue position between the distance etc. to for rescuing to excavate and provide scientific foundation. Along with the continuous movement of the life detection instrument, updated positioning, vital sign and other data are displayed in real time, so that quick and accurate support is provided for research and judgment of rescue actions.
In addition, the invention also provides a system for seeking help for tunnel personnel, which comprises a life detector and the electronic tag for seeking help for tunnel personnel introduced in the embodiment.
The life detection instrument of the rescue team is matched with the electronic tag worn by the tunnel personnel to form a complete and independent system for asking for help. After tunnel collapse appears, each electronic tags forms signal communication with the life detection instrument of saving the team and exchanges, and forms the network of building oneself between the electronic tags that the tunnel personnel wore and the electronic tags to transmit the ID number and the relevant information of one or numerous electronic tags to the life detection instrument, the life detection instrument can in time report out personnel's statistics of quantity that can spy out on its display screen, when the electronic tags that the spy was arrived is being close or keeping away from, the reputation of usable different frequencies shows the far and near distance etc. of personnel and probe.
In summary, the electronic tag for tunnel personnel help seeking and the help seeking device and system using the same of the invention convert the tunnel personnel from 'passive finding' to 'active help seeking', provide a reliable technical means for rescue actions of rescue personnel, thereby saving rescue time, improving rescue efficiency, effectively overcoming various defects in the prior art and having high industrial utilization value.
