Abstract

The utility model relates to a smog linkage controller, comprising a power supply circuit, a smog detection circuit, a switch trigger circuit, a wireless emission circuit, and a linkage exhaust circuit, wherein the power supply circuit provides circuit voltage; an output signal of the smog detection circuit is transmitted to the switch trigger circuit; and an output signal of the switch trigger circuit is transmitted to the wireless emission circuit and the linkage exhaust circuit. When smog is detected, the smog linkage controller is capable of automatically opening an air discharge fan and simultaneously sending alarm information to a host through the wireless emission circuit.

Description

A kind of smog linkage controller

Technical field

The utility model relates to a kind of detector, particularly be a kind of smog linkage controller.

Background technology

Traditional smog-control device is general to adopt wired or wireless mode to report to the police as transmission, but the restriction of the mounting distance of smog-control device, and can't realize remote alarms.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of smog linkage controller of energy remote alarms is provided.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of smog linkage controller, comprise power-supplying circuit, smoke detection circuit, switch triggering circuit, radio transmitter and interlock exhaust circuit, described power-supplying circuit provides circuit voltage, the output signal of described smoke detection circuit is transferred to the switch triggering circuit, and the output signal of described switch triggering circuit sends to radio transmitter and interlock exhaust circuit.

Described smoke detection circuit adopts the HQ-2 smoke transducer to gather smoke signal.

Described switch triggering circuit adopts TWH8778 electronic switch IC2.

Described radio transmitter adopts FDD400 transmitter module IC1.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: when the utility model detects smog, can open vent fan automatically, send warning message by wireless transmitter module to main frame simultaneously.

Description of drawings

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, a kind of smog linkage controller of the present utility model, comprise power-supplying circuit 1, smoke detection circuit 2, switch triggering circuit 3, radio transmitter 31 and interlock exhaust circuit 32, described power-supplying circuit 1 provides circuit voltage, the output signal of described smoke detection circuit 2 is transferred to switch triggering circuit 3, and the output signal of described switch triggering circuit 3 sends to radio transmitter 31 and interlock exhaust circuit 32.

The electric main of 220V is through transformer T step-down, and after diode VD1, VD2 full-wave rectification, capacitor C 1 filtering and the 7805 voltage stabilizer IC3 voltage stabilizings, output 5V DC voltage is supplied with local circuit and used.

Described smoke detection circuit 2 adopts the HQ-2 smoke transducer to gather smoke signal, the 5V DC voltage is supplied with the HQ-2 smoke transducer after resistance R 1 step-down, when in case the HQ-2 smoke transducer detects smog, its conductivity increases rapidly, the potentiometer RP two ends pressure drop that its output terminal is connected also increases, when the input terminal voltage that reaches TWH8778 electronic switch IC2 is 1.6V, the output terminal of TWH8778 electronic switch IC2 is high level by low transition, this signal is input to FDD400 transmitter module IC1, sends warning message by carrier frequency being modulated the back to main frame receiver module circuit.

Because TWH8778 electronic switch IC2 output high level signal, this signal through resistance R 3 current limlitings, make the inner conducting of photoelectrical coupler IC, output low level promotes the relay J adhesive, and the contact J1 of relay J transfers normally closed point to, connects the vent fan power supply, the mist of outwards discharging fume; After treating that indoor smog drains, the conductivity of HQ-2 smoke transducer greatly reduces, potentiometer RP two ends pressure drop is less than 1.6V, the output terminal of TWH8778 electronic switch IC2 recovers low level state, photoelectrical coupler IC is in cut-off state, the contact J1 of relay J transfers normal battle to, cuts off the vent fan power supply.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
