CN201698539U - Alarm controller - Google Patents

Abstract

The utility model relates to an alarm controller. The alarm controller comprises an alarm, a control interface, two metal contacts, a power supply and a relay, wherein one trigger end of the relay is in direct electrical connection with one metal contact, while the other trigger end is electrically connected with the other metal contact through the power supply; controlled ends of the relay include a normally-open end, a switch end and a normally-closed end, the normally-open end is electrically connected with a pole of the power supply through the alarm, and the switch end is in direct electrical connection with the other pole of the power supply; and the normally-closed end and the switch end of the relay are further connected with the control interface through conducting wires. When the two metal contacts are connected, the relay is driven by the power supply, the switch end and the normally-open end of the relay are electrified to drive the alarm to send out an alarm, and the control interface is disconnected. The utility model has the advantages of simple structure, cheap price, and low possibility of external interference, thereby achieving high practicability.

Description

A kind of alarm controller

Technical field:

The utility model relates to a kind of controller, especially a kind of alarm controller.

Background technology

Common alarm controller complex structure, cost an arm and a leg, can not be accepted by people.

Common alarm controller is subjected to extraneous interfere (as: thunder and lightning, high-intensity magnetic field etc.) easily, therefore all inconvenience uses of many places.

The utility model content:

The purpose of this utility model just is the deficiency at prior art, and a kind of alarm controller is provided, its low price not only simple in structure, and tool does not also allow to be subject to extraneous the interference, very practical.

Realize that the technical scheme that the utility model purpose is adopted is: a kind of alarm controller, it comprises an alarm, a control interface is characterized in that:

It also comprises two hard contacts, a power supply, a relay;

The trigger end of described relay, an end directly is electrically connected with a hard contact, and the other end is electrically connected with another hard contact by power supply;

The controlled end of described relay comprises a Chang Kaiduan, a switch terminals, a normal-closed end, and its Chang Kaiduan extremely is electrically connected with power supply one by alarm, and its switch terminals directly is electrically connected with another utmost point of power supply;

The normal-closed end of described relay also is connected with control interface by lead with switch terminals.

The utlity model has following beneficial effect:

1, its low price not only simple in structure of the utility model, and tool does not also allow to be subject to extraneous the interference, very practical.

2, the utility model design is unique, novel, makes easily, produces easily.

3, the utility model is simple and practical, has very big market outlook, can be widely used in fields such as home security, automobile burglar.

Description of drawings:

Fig. 1 is a structured flowchart of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, a kind of alarm controller, it comprises an alarm, a control interface, two hard contacts, a power supply, a relay; The trigger end of relay, an end directly is electrically connected with a hard contact, and the other end is electrically connected with another hard contact by power supply; The controlled end of relay comprises a Chang Kaiduan, a switch terminals, a normal-closed end, and its Chang Kaiduan extremely is electrically connected with power supply one by alarm, and its switch terminals directly is electrically connected with another utmost point of power supply; The normal-closed end of relay also is connected with control interface by lead with switch terminals.When two hard contacts are connected, relay is by power drives, the switch terminals of relay and Chang Kaiduan conducting, and alarm is driven warning; Control interface opens circuit simultaneously.

Ultimate principle of the present utility model and principal character and advantage have more than been described.The technician of the industry can understand; the utility model is not restricted to the described embodiments; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all will fall in claimed the utility model scope.
