The invention relates to systems for monitoring parameters of drilling oil and gas wells, namely, devices for collecting process information from remote controlled points installed in drilling rigs, as well as its transmission to a control center, and is additional to aut. St. No. 9646S2.

The aim of the invention is to increase the speed of the device by reducing the signal conversion time at the reception.

FIG. i shows the functional scheme of the control room; in fig. 2 - functional frequency multiplier circuit.

The control unit of the device consists of a driver, I address frequencies, containing b. uk 2 input generator 3i - 3; address frequencies and switch 4 addresses; defining generator 5, comprising generator 6, trigger 7, key 8 and divider 9; Frequency converter 10 - code, containing 1 I / O block 1 1, register 12, analog digital converter 13; a 14 clock decoder consisting of a 15 clock distributor and a relay 1 block 16 of the transceiver mode 16, a start block 17, a transceiver 18, multiply 19, containing (FIG. 2) an And (: K; 1YuCH) element. FULL or 20, resistor 21 and capacitor 22.

The device works as follows.

When the UBM program is accessed, the input block 2 (it controls the control signal and the ad- |) is called the maximum number of the controlled point (control dial,: 1 setting, 1 trigger control 7 on the unit, and key 8 opens, allowing the control signal not) ator D) through the detitel of 9 frequencies on the split) food, i1del 15. The address of the called CG1 will switch to the commutator 4 addresses and go to the address (1 follower} 1O in time two address parts from the set of address frequencies 01 generators 3i 3, to the input of the transceiver 18. But the third state of the distributor 15 is the switching unit 16 the transceiver mode switches the transceiver 18 from the mode "Redirect to the mode" Reception. In the subsequent state 1 ... P + 1 of the distributor, the transmitted parameters are received from the monitored item, the startup block 17) organizes the signals "Reset and" Start , 1a; and) 1h) -piff | 1k) convert. T 13. Analogue1) -digital receiver 13 successively during the time transforming the receipt frequency) 1 ... I1 parameters. At the end of the measurement, block 13 generates a signal for the end of the operation, according to which the value of a (a) of register register 12 is transmitted to block 11 above. The first information parcel on the block is 13 volts, 1 is the frequency of the receipt, KoiopaH is very significant; it is the no. Meter B1) |; About congro, 1I () cu.K) 1 point. Programming | |

The receipt can evaluate the accuracy of the call to the control center and, in the event that the frequency of the receipt does not correspond to the number of the controlled item, do not process the subsequent information. In the last state, distribute, l 15, the transceiver mode switching unit 16 switches the transceiver 18 from the "Receive" mode to the "Transmit." The control room is ready for the next CP call.

From the transceiver 18 of the control room after detection, a sequence of frequency signals corresponding to the input parameters of the controlled point equal in duration to the clock interval is sent to frequency multiplier 19 and then to the third input of frequency-code converter 10, to the first input of which clock pulses are received in duration compared with the known device by a number of times equal to the multiplication factor of the frequency of the BHOD11X signals. From the output of the frequency converter 10, the code information in the parallel binary code is transmitted to the PSU. The last clock cycle is the master oscillator.

As a frequency multiplier, you can use, for example, a frequency doubler, a functional diagram of which is shown in FIG. 2. The main element of the multiplier is the logical element EXCLUSIVE OR 20, which forms at the output pulses on the leading and trailing edges of the input pulses. The duration of the output pulses depends on the magnitude of the elements R and C.

The multiplication factor of block 19 is equal to the reduction ratio of the frequency converter conversion time — the code, the frequency multiplier input is connected to the output of the transceiver, and the output is connected to the frequency converter input — code, P) :) and this.the reduction of the polling time is achieved by reducing the conversion time frequency in the code and a multiple of reducing this time by multiplying the frequency of the detected information signal.
