Abstract
The utility model discloses a signal transmitting apparatus used for transmitting the number, the type and the running position of a locomotive in the safety monitoring system of rail haulage in underground mines. The circuit design of the transmitting apparatus applies various anti-interference techniques on the software design to guarantee normal work in the underground environment.
Description
The utility model relates to a kind of sender unit that mine under-well track transportation safety monitoring system is implemented monitoring that is used for.
Computer-controlled underground orbit transportation safety monitoring system comes into one's own.Sensing device in the main haulage roadway of down-hole on each site should be able to locomotive by the time collect license number by locomotive, parameters such as car type, after the processing, with the position of locomotive in service operation, parameters such as license number, car type are given component computer.Each locomotive identification that component computer collects each sensing device of total system, whether the operation anterior position of each locomotive is handled, analyzes, judged automatically in the car type and the position thereof of traction, judge in its place ahead and other locomotive operation intersection; Judge the current priority of intersection locomotive; Show red light for the locomotive that does not allow to move forward; To the locomotive green light that allows to move forward; If also will move track switch, just send instruction and move track switch automatically.The above-mentioned course of work realizes underground orbit transportation automation, comprehensive security monitoring.
When also once having the sender unit of development in the good environment of ground, to try out, can reliably launch the locomotive in service license number, but after moving on to the scene, down-hole, can not reliably working.
The utility model need be developed at this safety in production.It by be installed on the locomotive emitter and along forming of installing in the main haulage roadway of down-hole with its supporting signal receiving device two big parts.In locomotive operation, emitter provides the place locomotive identification in the binary-coded decimal mode, on individual position with hexadecimal A, B, C, D, E, the F sign indicating number provides car type respectively.The carrier of signal transmission is an infrared rays, also can be ultrasonic wave, radio wave or laser.When locomotive passed through receiving system, receiving system collected signal, after single-chip microcomputer is handled, sent component computer locomotive in service position, license number, car type signal, to realize the comprehensive security monitoring of underground orbit transportation system.
The utility model has adopted interference protection measure in electronic circuit, software design, can reliably working in subsurface environment.
The purpose of this utility model is achieved in that
Fig. 1 provides the utility model erector mapping.
In down-hole haulage drift (5), some receiving systems (2) are installed on the way, each receiving system is connected with component computer (3) via signal transmission wire.Each locomotive (4) is gone up an emitter (1) is installed.
The infrared signal that emitter (1) sends is given receiving system (2), and the signal after receiving system (2) will be handled is given component computer (3).
Fig. 2 provides the sender unit block diagram.
Used integrated packages such as single-chip microcomputer in the electronic circuit, they need the DC5V power supply.Be difficult to the DC5V power supply that provides high-quality on the locomotive.The miner is DC4V with mineral light or is lower than DC4V's on the mine.The complete system of an existing cover in use, management, this emitter is used mineral light can simplify mine management, and secondary power supply promotes voltage stabilizing with DC4V mineral light voltage and arrives DC5V, guarantees the emitter steady operation, prevents the electrical network noise jamming simultaneously.
Perhaps, utilize locomotive mains lighting supply DC24V to power to sender unit, its secondary power supply is a uninterrupted power source, and power supply quality satisfies the requirement of SCM system, and prevents that reliably interfering signal from entering this sender unit by power supply.
The place locomotive identification, the tractor-trailer train car type is provided by a kind of switchette, walks abreast to send single-chip microcomputer, scm software to be stored among the EPROM, and single-chip microcomputer processes the signal into the serial code of certain baud rate, amplifies modulation after infrared light-emitting diode sends.
At the down-hole complex electromagnetic fields, dust, in the wet environment, infrared rays has higher antijamming capability.
Adopt the frequency modulation system, in subsurface environment, have higher antijamming capability.
" agreement " between the software of emitter and the software of receiving system prevents assorted signal intrusion; Because stream oriented device is among the relative motion all the time, when receiving system software begins the signal of " reading " collection, be difficult to read, for preventing " reading " one-tenth " error code " from the start bit of signal, before each group signal code, one group " pilot codes " is set, guarantees that signals collecting is correct.
