Technical field
The utility model relates to gear case monitoring temperature field, specifically refers to the gear case intelligent monitor system in industrial circle.
Background technology
During gear case work, the friction of gear raises the temperature of lubricating oil.Under abnormal conditions, meeting as bad in lubrication oil circulation causes gear case temperature to exceed very soon limit value.Thereby gear case temperature is carried out to on-line monitoring, effectively forecast system duty, avoids occurring security incident.Temperature monitoring is a kind of proven technique, industry-wide temperature monitoring system adopts wired mode signal transmission mostly, yet in work under bad environment, for electrical wiring complexity and occasion difficult in maintenance, wired mode has suitable limitation, adopt wireless way for transmitting data, can effectively avoid these problems.In addition because signal pickup assembly is generally positioned near monitored target, require supervising device can meet needs non-stop run in 24 hours of on-line monitoring, therefore the power consumption of collection terminal must be very low, the selection of device must meet low-voltage support and low-power consumption requirement, adopt the mode of wired installation to have wiring and shortcoming difficult in maintenance, and the higher problem of power consumption, also can have influence on power supply and signal transmission availability simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of have high-timeliness, the high and low power consumption of automatic intelligent degree, can adapt to complex work environment, and the gear case intelligent monitor system in the simple industrial circle of installation and operation.
The utility model is achieved through the following technical solutions: the gear case intelligent monitor system in industrial circle, comprise the digital sense protractor, PIC single-chip microcomputer, scrambler, carrier generator, infrared transmitting tube, infrared receiving terminal, demoder and the PIC microprocessor that connect successively, and the microcomputer monitoring chip, the power circuit that are connected with PIC single-chip microcomputer respectively, the microprocessor monitors chip, the liquid crystal display that are connected with PIC microprocessor respectively.Digital temperature sensor is exported temperature signal in the mode of 12 bit digital quantity, and scrambler completes the transmission of tetrad data information at every turn only.When single-chip microcomputer receives 12 temperature signals, first be split as high, medium and low four, then give every coupling with corresponding address signal, then give scrambler, therefore adopt the method for this partition address transfer can effectively avoid the not problem of coordination communication confusion.In addition infrared emitting distance is directly proportional to emissive power, therefore by carrier generator, can solve the transmitting range problem of infrared light.Because existing PIC single-chip microcomputer, PIC microprocessor and wireless communication technology belong to mature technology, and improvement of the present utility model do not lie in this, therefore repeat no more structure and the principle of work of PIC single-chip microcomputer, PIC microprocessor and Infrared Wireless Communication technology.
Further, described PIC single-chip microcomputer is also connected with liquid crystal display, and described liquid crystal display is dot matrix lcd.
Further, described PIC microprocessor is connected with power circuit.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment 1:
The remote intelligent transformer burglary-resisting system course of work of the present embodiment as shown in Figure 1, digital temperature sensor exports in the mode of 12 bit digital quantity the temperature signal collecting to PIC single-chip microcomputer, real time temperature data are shown by liquid crystal display simultaneously, after processing, PIC single-chip microcomputer transfers to scrambler, and scrambler completes the transmission of tetrad data information only at every turn, therefore when single-chip microcomputer receives 12 temperature signals, first be split as high, medium and low four, then give every coupling with corresponding address signal, then give scrambler.Adopt the method for this partition address transfer can effectively avoid the not problem of coordination communication confusion.After coder processes, temperature signal data is carried out carrier processing by carrier generator again, by reducing carrier pulse dutycycle, can effectively improve peak point current not increasing under the prerequisite of system power dissipation, thereby increases the operating distance of infrared emission.Signal after carrier processing is emitted to infrared receiving terminal via infrared transmitting tube and receives, and the data-signal of reception decode after processing and transferred to PIC microprocessor by demoder.PIC microprocessor is first sent into demoder the corresponding address signal setting in advance, through the data-signal receiving is proofreaded, decoding and error correction, then exports.If the address information comprising in the data-signal receiving and local address information are not inconsistent, be considered as invalid data.After address check is correct, demoder just starts data decode to process, and after completing, the effective output terminal output of reception data high level, represents that decoding is effective.After inquiring decoding effective marker, PIC microprocessor again next addresses signal is sent into demoder.In decode procedure, adopted integral element, demoder is not directly decoded to the pulse signal receiving, but will after input signal integration, decode again.Because the spike pulse of integrating circuit energy filtering moment is disturbed, even so the coded signal that receives of demoder be subject to the interference of certain program, still can be correctly decoded, this industry spot for circumstance complication is particularly important.System display section adopts two kinds of display modes, and a kind of is to utilize serial data transmission mode and upper PC, and the abundant graphical interfaces of PC demonstrates the temperature of current equipment under test; Another kind is the liquid crystal display displays temperature by system monitoring receiving end, can meet the requirement of on-the-spot and remote temperature monitoring simultaneously.Because PIC single-chip microcomputer, PIC microprocessor and Infrared Wireless Communication technology belong to mature technology, and improvement of the present utility model does not lie in this, those skilled in the art can draw setting and the course of work of PIC single-chip microcomputer, PIC microprocessor and Infrared Wireless Communication technology by basic general knowledge, therefore do not indicate in detail in Fig. 1, therefore yet it is not illustrated and repeated no more in detail.
