Abstract
The utility model relates to a signal receiving and transmitting device for carrying out wired control on a remote working main machine, which is formed by that a receiving device and a transmitting device are connected by a conducting wire. The base electrode of each transistor used as a signal receiving element is connected with a signal conducting wire through a voltage stabilizing tube and a resistor, and a collector electrode is matched with a corresponding control relay, so that a new wire controlled transistor bidirectional transmitting and receiving device with simple structure, strong reliability and adaptability of wide range is formed.
Description
The utility model is that a kind of host implementation has the signal receiving/transmission device of line traffic control to telecommute.
When the cable gas-feeding equipment of field work was implemented far distance controlled, many directly employing electromagnetic type relays were as the reception and the executive components of control signal at present.This mode is often very harsh to the requirement of command range, can make the driving force variation because of current attenuation when distance is longer, distance can make the executive component heating more again because drive current is excessive and reduce serviceable life, and this just brings bigger difficulty for engineering design and construction.
The purpose of this utility model is that based on now quite ripe electronic technology theory, it is few to design a kind of highly sensitive consumed energy, apart from the wide line traffic control transistor bidirectional transmitting/receiving device of the scope of application, to solve the shortcoming that exists in the above-mentioned prior art.
The utility model is made of two parts R-T unit that lead connects, its base stage of each transistor as signal receiving element all is connected with signal conductor by stabilivolt and resistance, be equipped with the corresponding relays control circuit again at collector, thereby constituted simple in structure, good reliability has very width from the novel line traffic control transistor bidirectional transmitting/receiving device of adaptive faculty.
When prosecution is implemented control, master is sent the instruction of direct current high level to prosecution, the transistor base conducting of prosecution, feasible relay adhesive and the self-locking that is in collector, be that attracting state remains unchanged, because transistor base only needs very little conducting electric current when conducting,, and can expand to many group devices to above single group device according to actual needs and use so this R-T unit has the very wide scope of application to the length of pilot.
Accompanying drawing 1 is the circuit diagram of an embodiment of the present utility model.The numbering and the classification of the alphanumeric representation components and parts among the figure, pure digi-tal are represented the contact numbering of relay.
