Abstract
A pressure signal wireless alarm for oil field mine transfer consists of an electric contact pressure meter 2, an emitting circuit, a receiving circuit, etc. A meter shell 1 is provided with the electric contact pressure meter 2, the emitting circuit, and the receiving circuit; the input end of the electric contact pressure meter 2 is connected with the anode of the power supply of the emitting circuit while the output end is connected with the cathode of the power supply of the emitting circuit; the pressure is not required to be checked by patrol of the watchkeepers; if the pressure reaches the upper limit or the lower limit, the sound and light alarm is sent out to the watchkeepers who can timely judge and dispose according to the prompted pressure electric position, the accident caused by the pressure is effectively avoided, and the labor intensity of the watchkeepers is relieved.
Description
The utility model relates to a kind of defeated pressure signal wireless alarm of oil field mining site collection that is used for.
At present, the pressure of the wellhead pressure of oil well, water injection well, the container pressure of pumping plant, collection transmission pipe network all is to gather pressure parameter by operator on duty's inspection trips, 2 hours cycles or 4 hours of general inspection trips, as not being when checking, pressure parameter has suddenly significantly variation, can cause serious accident, it is quick-fried to cause container explosion or pipeline to suppress, sometimes even cause casualties.
The purpose of this utility model is to provide a kind of operator on duty's of need not inspection trips pressure, makes the pressure signal wireless alarm of the ultimate value of pressure by sound and light alarm.
The utility model is achieved in that by watchcase 1, electro connecting pressure gauge 2, indicator 3, radiating circuit, receiving circuit to be formed, and electro connecting pressure gauge 2, radiating circuit, receiving circuit are arranged in the watchcase 1, and indicator 3 is arranged on the electro connecting pressure gauge 2.
The utility model also adopts following technical scheme:
The positive pole of the input end of electro connecting pressure gauge 2 and radiating circuit power supply joins, and the negative pole of its output terminal and radiating circuit power supply joins.
Advantage of the present utility model is: without operator on duty's inspection trips pressure, can give the operator on duty by sound and light alarm as pressure to the upper limit or lower limit, the operator on duty can in time judge and handle according to the pressure electric position of alarm, the accident of having avoided effectively causing because of pressure takes place, and has alleviated operator on duty's work.
Fig. 1 is synoptic diagram of the present utility model and radiating circuit figure;
Fig. 2 is receiving circuit figure of the present utility model.

1-switch, the J-relay.
As shown in Figure 1, the input end of electro connecting pressure gauge 2 and the positive pole of radiating circuit power supply DC are joined, the negative pole of its output terminal and radiating circuit power supply DC joins, when the extreme pressure of electro connecting pressure gauge 2 reaches P

1Switch closure, the limit signal of electro connecting pressure gauge 2 outputs to the input end of scrambler AN801 from output terminal, AN801 is a kind of dual-in-line 16 pin coding integrated circuit, it is provided with 5 bit address sign indicating number A1-A5, every bit address sign indicating number has three state, promptly 0,1 and open-circuit condition, so can form 243 sign indicating numbers, can increase a group again, total several Lu Keda 15 * 243=3645 road, utilize address code and numeric data code that alarm set point is compiled number in order, the characteristics pulse width of utilization is transmitted each road signal respectively, and address code and numeric data code adopt miniature combined switch, and is consistent with the coding of decoding from line number, coded pulse signal after well is handled is exported through 15 pin, through capacitor C 3 input RX5019 transmitter modules, coded pulse signal is modulated into the FM mode, emission output, its technical parameter is that frequency modulation is ± 3KHz, carrier frequency is 30MHz, and radio frequency power output is not less than 5W, operating voltage DC15V ± 2V, working current is not more than 1A, the amplitude V of input modulating signal
P-P=1V, input impedance is 600 ohm.
As shown in Figure 2, receiving circuit arrives the RX5020 receiver module to the high-frequency signal of radiating circuit by wireless receiving, inside is carried out mixing and is amplified, behind the frequency discrimination, import from 9 pin of AN802 decoder ic after the pulse code signal of mediating outputs to F1, the shaping of F2 phase inverter separating, through direct impulse of 11 pin of AN802 output, this pulse after F3 is anti-phase, import IC4 (CD4514) forbid hold the 23rd pin, make the gating control gate of IC4 open-minded.
CD4514 is one four and latchs the 14-16 line and translate device (output height choose) integrated package that it is provided with the input latch of gating control, translates when middle when the scale-of-two horsecloth of input, and corresponding output terminal changes high level.In the 11 pin output coincidence impulse signal of IC3, the 12-15 pin of IC3 is exported four figures simultaneously according to sign indicating number, just restores the 1-15 road corresponding signal of former transmission through IC4 decoding, and is exported by 4-11, the 13-20 pin of IC4 respectively.That report to the police as transmitting terminal is LED the 5 tunnel, and then the 8th pin of IC4 becomes and transmits high level, the 5 tunnel of LED, and this paths of LEDs is just bright, because LED1-LED15 and connecing, so, all can make driving stage V1 run and conducting the alarm sound circuit working no matter which paths of LEDs is bright.Because IC44514 has latch function, in case after triggering warning, even alerting signal is stopped paying out, the warning LED on this road is still glittering, alarm sound does not stop, and stops to report to the police after power reset is turned off in operator on duty's arrival.If address code signal that IC3 receives and not meeting of presetting, then 11 pin of AN802 are low level always, can not make the inhibit gate of IC44514 open-minded, and its each output terminal all is low level, and LED does not work, and alarm sound does not ring.
Radiating circuit and accept the reasonable disposition of no device between the circuit and cooperatively interact to have realized the purpose of pressure signal radio alarming has solved oil field mining site collection and has raise suddenly or reduce the pernicious industrial accident that causes because of pressure in defeated.
