The invention further relates to a method for a safety management in an underground mine.
Mine environment is considered to be one of the most dangerous working environments. There are hundreds of deadly accidents each year in coal mines in all over the world. Unfortunately, reliable and easy to use safety systems do not exist.
Brief description
Viewed from a first aspect, there can be provided a safety network system of an underground mine, comprising a monitoring system, plurality of reader devices, each of which being arranged in a known location in said gal- lery, and being capable to communicate with the monitoring system, at least one wireless safety device having capacity to communicating with the reader devices, wherein the location of said at least one wireless safety device in the mine is arranged to be provided by the monitoring system, and wherein said communication is arranged to operate at 433MHz.
Thereby a safety network system that is reliable and that can be easily integrated to the existing mine network systems may be achieved.
Viewed from a further aspect, there can be provided a method for a safety management in an underground mine, the method comprising: arranging a monitoring system for monitoring and controlling the safety management, arranging plurality of reader devices at fixed locations in said gallery, utilizing at least one wireless safety device having capacity to communicating with the reader devices, and complying said communication at 433MHz.

The system and the method are characterised by what is stated in the characterising parts of the independent claims. Some other embodiments are characterised by what is stated in the other claims. Inventive embodiments are also disclosed in the specification and drawings of this patent application. The inventive content of the patent application may also be defined in other ways than defined in the following claims. The inventive content may also be formed of several separate inventions, especially if the invention is examined in the light of expressed or implicit sub-tasks or in view of obtained benefits or benefit groups. Some of the definitions contained in the following claims may then be unnecessary in view of the separate inventive ideas. Features of the different embodiments of the invention may, within the scope of the basic inventive idea, be applied to other embodiments.
ISO 18000-7 is a global standard for e.g. Dash7 technology. It operates at 433MHz, which is penetrating well through the rock. Thus ISO 18000-7 enables great range also underground.
Good signal penetration enables good locating accuracy and short latency time makes it suitable for alarms. Worst case latency is 2 seconds.
Systems operating at 433MHz, such as ISO 18000-7, have extremely low power consumption, so it can be used several years in battery powered mode.
The safety network operating at 433MHz is capable for multi- hopping i.e. the network is able to recover even though the cabling system is damaged. This kind of situation may be generated e.g. in accidents taking place in the gallery of the mine.

Figure 1 is a schematic side view of an example safety network system in partial cross-section.
The safety network system 1 of an underground mine 2 comprises a monitoring system 3, and an optional cabling system 4 arranged at least partly in the gallery 5 of said mine 2. The safety network system 1 further comprises plurality of reader devices 6 each of which being arranged in a known location in the gallery 5.
The safety network system 1 further comprises at least one wireless safety device 7 having capacity to communicating with the reader devices 6. This communication is arranged to operate at 433MHz, e.g. comply with ISO 18000-7 standard, e.g. Dash7.
In the embodiment shown in Figure 1 , the reader devices 6 are connected to said cabling system 4. The cabling system 4 is arranged to deliver electric power for the reader devices 6 and it also may take care of communi- cation between the reader devices 6 and the monitoring system 3.
The distance between adjacent reader devices 6 depends on locating accuracy requirement. According to an idea, said distance is in the range of few meters to tens of meters, for instance.
The cabling system 4 not only delivers power for the reader devices 6, but also takes care of communication between the monitoring system 3 and the reader devices 6. The monitoring system 3 is providing an interface, which provides information e.g. about the location information of the wireless safety device 7.
The monitoring system 3 may comprise e.g. control room where the information provided by the safety monitoring system 1 is presented for controller personnel, or monitoring equipment arranged for use of supervisor or manager of the mine 2, etc.
The communication taking place between the monitoring system 3 and the wireless safety device 7 may also be conducted wirelessly 16.
The wireless safety device 7 may be attached to the personal gear of an individual, e.g. a miner, or devices working in or for some other reason being in the mine 2.
In an embodiment the present system and method, the safety monitoring system 1 is also providing information about at least one of the following variables: variables relating to the environment in the gallery of the mine 2, and variables relating to the vital functions of the individual carrying the Wireless safety device 7.
Said variable relating to the environment in the gallery 5 may relate to e.g. gas content or temperature of said gallery 5.
Said variable relating to the vital function of the individual carrying the Wireless safety device 7 may relate to the physical motion to detect activity level of the individual, or heart rate or blood pressure or body temperature of said individual.
The data about said variables is created by respective sensor(s) 8 arranged in the gallery 5, in devices 9 moving in the mine 2 and/or in personal gears 12 of individuals 10 in the mine 2.
The safety monitoring system 1 may create alarms in case where the value of at least one of said variables is outside of the safe range defined therefor.
The personal gear 12 may further include a personal safety device 13 for collecting, management and/or handling of data received from the sensors) 8 arranged in said personal gear 12.
The personal safety device 13 comprises a receiving unit 14 for receiving data from the sensor(s), and a transmitter unit 15 capable to transmit said data with the reader devices 6.
According to an embodiment, the personal safety device 13 may also receive and transmit data received from sensor(s) 8 of another individual 10 and/or sensor(s) 8 arranged in moving devices 9 or gallery 5.
The communication from the sensor(s) 8 to the personal safety device 13 may be communicated by Bluetooth, Zigbee, WLAN, Ant+ or any known wireless system known per se. It is also possible to use wired communication from the sensor(s) 8 to the personal safety device 13 included in the same personal gear 12.
The reader device 6 comprises preferably a battery or accumulator based backup power unit 1 1 . Due to the battery backup power unit 1 1 , the reader device 6 operating at 433MHz, such as ISO 18000-7 standard based reader device, may operate years even though the cabling system 4 is broken.
The wireless safety device 7 operating at 433MHz, such as ISO 18000-7 standard based wireless safety device can be attached or integrated to the miner's support system, e.g. to his/her helmet and/or equipment belt and/or as attached like a plaster. Alternatively, the Wireless safety device 7 may be attached or integrated to devices in the gallery, especially to moving devices, e.g. carts.
The safety network system 1 may utilize the real-time locating system capabilities, e.g. of ISO 18000-7 standard technology. Locating of e.g. the individual 10 is based on the received signal strength indicator (RSSI). Also other localization methods can be used. Commonly used alternatives are Time of Arrival (TOA), the Time Difference of Arrival (TDOA) and the Round Trip of Flight (RTOF) methods. The TOA method is based on the fact that the distance between the reader and the tag is directly proportional to the flight time of the signal. The TDOA method is also based on the signal flight times. The TDOA method does not required an accurate clock synchronization between the tag and the reader like in the TOA method, but the synchronization is performed between readers. The RTOF method is also based on the flight time, but contrary to the TOA all measurements are made by the tag, which measures the time between sending a message to the reader and receiving a response message. The RSSI method is based on the fact that in free space the attenuation of the signal is inversely proportional to the square of the distance between the reader and the tag.
Due to the long communication distance of wireless safety device 7 operating at 433MHz, e.g. using ISO 18000-7 standard, is able to communi- cate with several reader device 6 simultaneously. Therefore, triangulation may be exploited in calculating the location of the device 9 or the individual 10. The accuracy of the locating process is better if there are many reader devices 6 inside the communication range of the tag 7.
In the case of an accident, the safety network system 1 can be re- covered. For example if wire between reader devices 6a and 6b in Figure 1 is broken, or between the reader device 6a and the monitoring system 3, the signal can be routed wirelessly between said reader devices 6a and 6b, or between the reader device 6a and the monitoring system 3, respectively. Reader devices 6c and 6d following the marker 6b go then to a battery powered mode, and all locating processes, sensors and alarms operate same way than prior the accident.
According to an embodiment, the safety network system 1 transmits information bi-directionally, i.e. not only from the gallery 5 to the monitoring system 3, but also from the monitoring system 3 to the reader devices 6 and/or wireless safety device 7.
Figure 2 is a schematic side view of another example safety network system in partial cross-section.
The embodiment of the safety network system shown in Figure 2 is basically similar to that shown in Figure 1 . The most important difference is that there is no cabling system 4 in the system shown in Figure 2. The reader devices 6 are arranged to operate at 433MHz, e.g. to communicate according to ISO 18000-7 standard, and wirelessly 16 with the monitoring system 3.
The reader device 6 comprises a battery, accumulator etc. for source of energy.
The gallery 5 of the mine 2 comprises wireless safety devices 7 which may be arranged in devices in the gallery 5 or gears of miners or other individuals in the gallery 5.
The amount of the wireless safety devices 7 included in the system 1 may vary depending on the number of devices and individuals being in the gallery 5.
Figure 3 is a schematic view of an example wireless safety devices. Wireless safety devices 7 may be arranged in the personal gears 12 of a miner. In the embodiment shown in Figure 3, a wireless safety device 7 is arranged in the belt of the miner. Thus the wireless safety device 7 may serve as a personal safety device 13. The personal safety device 13 may communicate with reader devices 6 arranged in the mine. Said communication is realized by principles described already in the previous parts of this descrip- tion.The invention is not limited solely to the embodiments described above, but instead many variations are possible within the scope of the inventive con- cept defined by the claims below.
