Description

 The invention relates to communications and can be used in devices for receiving and transmitting discrete information.

 The aim of the invention is to expand the functionality of the device by ensuring its automatic switching from an active state to standby mode and vice versa.

 The drawing shows a structural diagram of a device.

 The device contains a first interface unit 1, first 2 and second 3 keys, a majority element 4, a first counter 5, an OR element 6, a second counter 7, a power supply 8, a first 9 and a second 10 load elements, a second interface unit 11, a group of controlled units 12 power supply, the first 13 and second 14 control inputs of the device, input 15 of the initial installation, input 16 prohibition off, input 17 manual control, clock input 18 of the device.

 The device operates as follows.

 In the initial state, the initial installation signal 15, passing through the OR element 6, sets the second counter 7 to zero, which means the inclusion of power supply units 12. The impact of the potential signal 16 prohibition of turning off the group of blocks 12 is similar. This signal is connected to the remote control.

 At the end of the signal 15 of the initial installation and the absence of reception and transmission of information to the inputs of the key 3 receives logical signals "1", which corresponds to the stop premise. In this case, at the reset input of counter 5 there is also a logical “1” signal that prohibits the counter from working, and a logical “0” signal is generated at its overflow output. In this case, from the output of the OR element 6, an enable signal is supplied to the reset input of the counter 7, and it counts the pulses arriving at its clock input. After the receipt of a given number of pulses at the overflow output of the counter 7, a logical "1" signal appears, disabling the group of power units 12 and blocking the further counter of the counter 7.

 In the absence of voltage on the power supply units 12, the keys 2 and 3 are closed, since zero potential is supplied to their control inputs through element 9. These keys disconnect the receiver and transmitter circuit of the telegraph apparatus, which was left without power, from the control device. Element 10 serves to maintain a stop signal at the input of element 4 with the key 3 closed.

 In the described state, the device is located until one of two events occurs: a manual start at input 17 or a starting package at the input of the first pairing unit 1.

 In the first case, the signal from the input 17 through the OR element 6 sets the counter 7 to its initial state, which removes the shutdown signal from the control inputs of the power supply units 12, and the device returns to its original state.

 In the second case, the signal of the starting parcel from the output of block 1 goes to the input of the majority element 4. At the output of element 4, a potential signal appears that allows the counter 5 to work, which serves to protect against impulse noise at the input of the device and at the output of the transmitter. If the duration of the starting parcel is such that the counter 5 has time to count before overflow, then a high level signal appears on its overflow output, which sets counter 7 to its initial state through the OR element 6. Turning off the power supply 12 occurs when the counter 7 has time to overflow.
