Description

This invention relates to the field of reference. The device can be used to collect, transmit and process information.

A device is known for transmitting digital information through a PBX containing a telephone connected to a line, a digital information HCTomimc, as well as a receiver connected to a line. tone frequency and ringing frequency generator 1.

However, in a known device, the transmission of information can be carried out only at the initiative of the subscriber. This reduces efficiency, requires the use of a number of manual operations, which ultimately reduces the speed of information transfer.

The aim of the invention is to increase the speed of data transfer.

To do this, the device for transmitting digital information through the PBX, containing a telephone set connected to the line, a source of digital information, as well as a tone frequency receiver and a ring frequency generator, are inserted into the ring frequency receiver and a generator of direct dial pulses. At that, the ring frequency receiver, square pulse generator and digital information source are connected to the communication line, the secondary input and the auxiliary output of the digital information source are connected to the first auxiliary output and the first auxiliary input of the tone frequency receiver, the second auxiliary input of the tone receiver partly connected with the first additional output of the receiver of the ringing frequency, the second additional output of which is connected to the auxiliary input of the generator ougolnyh impupsov, additional output square wave generator coupled to an additional input of the generator vyz PURITY thereof, an additional output coupled to a first additional

the telephone input, the second additional input of the telephone set is connected to the second additional output of the tonal frequency receiver, the third additional input; the output of which is connected to the liepefciM additional input of the high frequency receiver, the second additional input of the latter is connected to the additional output of the telephone set.

 In drawing 1. there is a structural electrical cxeiwa in front of the burning device.

A device for transmitting digital information through a PBX contains a source of digital information 1, a receiver of tone frequency 2, a receiver of calling frequency 3, a generator of rectangular pulses 4, a generator of calling frequency 5 and a telephone set (TA) 6:

The device works as follows. When the first ring of the calling frequency arrives at the input of the device, the receiver 3 is readily bored, which has the rise of the telephone line by the subscriber. In addition, the PBX devices establish a direct connection with the center for collecting and processing information. If then the impulse of the tonal frequency is often followed from the center, then; receiver 2 triggers, which connects digital information source 1 at the time of information transfer and disconnects THAT 6 at the same time. IF there is a normal communication setup for two subscribers, then the tone frequency pulse is missing and the ring frequency receiver 3 starts a square pulse generator 4. The latter connects the ringing frequency generator 5 to the TA ringing for the duration of its operation. When the subscriber calms down the handset, the ring frequency receiver, and subsequently, both the square pulse generator and the ring frequency generator 5 return to their original position. Thus, a direct connection is established between the subscribers for a conversation. Putting the handset after a conversation on the TA 6, there is a release to the PBX devices.

The proposed device can be used in the system of automatic

interrogation of meter readings, metering of electricity consumption by enterprises. In addition to the rapid generation of electricity consumption bills, it allows a direct influence on a number of key factors determining the quality of the power system, such as network losses, which allows for a semi-significant economic effect.
