The CC2431 minimum system is respectively connected with a temperature and humidity sensor, a warning display circuit and an emergency circuit. According to the movable underground mine information monitoring and personnel positioning device, a mine information monitoring system and a worker positioning system are combined, the structure is simple, communication cables do not need to be paved on site, and real-time underground state information can be obtained.
Description
Technical field
The utility model belongs to the coal information monitoring technical field, is specifically related to information monitoring and personnel positioning apparatus under a kind of portable coal mine.
Background technology
Along with coal industry is flourish, peace district, colliery accident happens occasionally, and to the country and people, causes huge loss.Therefore, essential to safety of coal mines information Real-Time Monitoring.Traditional mine monitoring mode mainly is divided into two kinds, and a kind of full-time staff of being is patrolled and examined, and while having potential safety hazard, the full-time staff takes certain measure, and this mode takes time and effort, and full-time staff's life security also can't be guaranteed; Another kind is that wired safety monitoring system is installed in down-hole, this mode has avoided the full-time staff to patrol and examine brought disadvantage to a certain extent, but this mode monitoring device can't advance landform and the environmental change of progress and down-hole complexity to coordinate mutually with coal production, and the cost great number.
Simultaneously, the track and localization that realizes the mine staff is to strengthen the effective measures of mine safety production, can allow the ground maneuvers chamber understand at any time the situation of down-hole, realizes personnel in the pit's scheduling and distribution, increases work efficiency.The down-hole personnel tracking system is all to adopt RFID(RadioFrequency Identification less radio-frequency basically at present) technology, this method is at mine well head place, or some critical passage mouths of other down-hole, the method for using radio-frequency card (RFID) to read records the method for following the tracks of to the personnel of going into the well.There is following several problem in this method: the tag card effective time is short, under high-speed condition, location personnel's loss is higher, positioning precision is low, unidirectional communication, and the rate of information throughput is low, function singleness.Existing RFID radio frequency read-write system (comprising SuperRFID), be difficult to realize personnel in the pit's zone location and personnel in the pit's work attendance, can not realize that personnel in the pit truly locates tracking.
The utility model content
The purpose of this utility model is to provide information monitoring and personnel positioning apparatus under a kind of portable coal mine, this device is carried by the underground work personnel, can realize the Real-time Collection of subsurface environment parameter and underground work personnel's real-time location, solved existing wired information monitoring system and RFID personnel location system cost is high, the tag card effective time is short, location personnel's loss is higher under high-speed condition, positioning precision is low, unidirectional communication, the rate of information throughput is low, the problem of function singleness.
The technical scheme that the utility model adopts is, information monitoring and personnel positioning apparatus under portable coal mine, comprise the CC2431 minimum system, be provided with the antenna for radio communication on the CC2431 minimum system, on the CC2431 minimum system, also be connected with firedamp sensor, CO sensor by first signal modulate circuit, secondary signal modulate circuit respectively.
Characteristics of the present utility model also are, are connected with respectively Temperature Humidity Sensor, alarm indication circuit on CC2431 minimum system wherein and call for help circuit.
The beneficial effects of the utility model are, this mobile message monitoring and personnel positioning apparatus select zigbee radio frequency chip CC2431 as data processing unit, can realize multiple subsurface environment parameter (gas, CO, temperature, humidity) is carried out the functions such as Real-time Collection, data demonstration, pernicious gas off-limit alarm and button emergency.Design the wireless sensor network personnel positioning based on range finding simultaneously, and utilized Kalman filtering effectively to improve positioning precision.The Zigbee network that under the coal mine that device obtains, monitoring information and personnel positions information cover via scene and the industrial loop ethernet of intermediate conveyor, data are sent to the ground monitoring center, for administrative staff provide the real-time ambient condition in down-hole and personnel positions.This device combines coal information monitoring and staff's navigation system, simple in structure, does not need scene to lay communication cable, can obtain down-hole real-time status information.
The accompanying drawing explanation
Fig. 1 is the structural representation of information monitoring and personnel positioning apparatus under the portable coal mine of the utility model.
In figure, the 1.CC2431 minimum system, 2. firedamp sensor, 3. Temperature Humidity Sensor, the 4.CO sensor, 5. the alarm indication circuit, 6. call for help circuit, 7. first signal modulate circuit, 8. secondary signal modulate circuit, 9. antenna.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure of information monitoring and personnel positioning apparatus under the portable coal mine of the utility model, as shown in Figure 1, comprise CC2431 minimum system 1, be provided with the antenna 9 for radio communication on CC2431 minimum system 1, firedamp sensor 2 and CO sensor 4 are respectively by first signal modulate circuit 7 and the different AD input pin of secondary signal modulate circuit 8 access CC2431 minimum system 1, Temperature Humidity Sensor 3 outputs are digital quantities, directly access the IO mouth of CC2431 minimum system 1, the digital I/O port of alarm indication circuit 5 access CC2431 minimum systems 1, call for help circuit 6 by the input pin connecting system of CC2431 minimum system 1.
Information monitoring and personnel positioning apparatus under the portable coal mine of the utility model, select the low-power consumption CC2431 wireless singlechip with hardware positioning engine, adopt the power supply of Ni-MH battery group, designed temperature, humidity, gas, the collection of CO and modulate circuit, take software approach to carry out calibration and compensation to sensor output value, the accurate detection of realization to above-mentioned information, use the LCM12232Zk of low-power consumption to show the environment parameter value gathered, designed sound light alarming circuit, can be reported to the police timely, and designed the emergency button, the personnel in the pit can be used for being called for help.
