Description

A kind of 16A on-off controller

Technical field:

The utility model relates to intelligent lighting control field, is specifically related to a kind of 16A on-off controller.

Background technology:

Energy-conservation, intelligence science and technology and aesthetics are the themes of 21 century building industry, and building industry is introduced the notion of " green " illumination, and this just need use intelligent lighting system.In intelligent lighting system, on-off controller is an indispensable part, can carry out switch control to the load of any kind of light source and non-light source.But on-off controller does not in the market have current sense function, and under the excessive situation of load current, in time turn-off circuit causes the bonding of the interior relay contact of on-off controller, shortens the useful life of relay; And integrated level is low, can not directly handle sensor signal, needs to cooperate other sensor signal receiving equipment, converts sensor signal to corresponding scene instruction, sends to the Kai Heguan that on-off controller is carried out corresponding circuit.

The utility model content:

The purpose of the utility model provides a kind of 16A on-off controller, and it has current sense function, and the protection contact prolongs the relay life-span greatly, can long-rangely also can local control open and close, and directly the processes sensor signal reduces the system equipment kind.Reasonable in design, simple in structure, integrated level is high, good reliability, and management maintenance is convenient, and the high economic return rate is arranged.

In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises bus 1, communicating circuit 2, single-chip microcomputer 3, relay circuit 4, current detection circuit 5, loop state indicator light 6, local switching circuit 7, sensor signal processing circuit 8; Bus 1 links to each other with communicating circuit 2, and communicating circuit 2, relay circuit 4, current detection circuit 5, loop state indicator light 6, local switching circuit 7, sensor signal processing circuit 8 all link to each other with single-chip microcomputer 3.

The utlity model has following beneficial effect: have current sense function, the protection contact prolongs the relay life-span greatly, can long-rangely also can local control open and close, and directly the processes sensor signal reduces the system equipment kind.Reasonable in design, simple in structure, integrated level is high, good reliability, and management maintenance is convenient, and the high economic return rate is arranged.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Embodiment:

Referring to Fig. 1, this embodiment adopts following technical scheme: it comprises bus 1, communicating circuit 2, single-chip microcomputer 3, relay circuit 4, current detection circuit 5, loop state indicator light 6, local switching circuit 7, sensor signal processing circuit 8; Bus 1 links to each other with communicating circuit 2, and communicating circuit 2, relay circuit 4, current detection circuit 5, loop state indicator light 6, local switching circuit 7, sensor signal processing circuit 8 all link to each other with single-chip microcomputer 3.

Workflow is: when the scene instruction was arranged on the bus 1, communicating circuit 2 was passed to single-chip microcomputer 3 with the scene instruction, and single-chip microcomputer 3 control relay circuits 4 open or close; Thereby switch control is carried out in the load of any kind of light source and non-light source, and the state in loop state indicator light 6 these loops of indication, a current detection circuit 5 is arranged on each relay circuit 4; The loop load current value is passed to single-chip microcomputer 3, calculate the real-time current value in each loop by single-chip microcomputer 3, and current value is in time fed back on the bus 1 through communicating circuit 2; When loop load current value during greater than the current maxima that is provided with; Single-chip microcomputer 3 turn-offs this loop, protection relay contact, and these loop state indicator light 6 alarms; Can pass through local switching circuit 7; Manually carry out the Kai Heguan in each loop, sensor signal processing circuit 8 will receive the analog quantity or the switching value signal of external sensor and pass to single-chip microcomputer 3, and the scene instruction that single-chip microcomputer 3 is corresponding with this signal sends on the bus 1 through communicating circuit 2; Self then carries out this scene instruction if need to carry out this scene instruction simultaneously.

Described bus 1 and communicating circuit 2; This embodiment utilizes bus 1 and communicating circuit 2 in time to deliver to host computer to the electric current in loop; Host computer also can send the scene instruction to the utility model through bus 1 and communicating circuit 2 simultaneously, and single-chip microcomputer 3 judges whether to carry out this instruction, carries out if need; Then reading this corresponding loop of scene instruction in the EEPROM opens or closes; Control relay circuit 4 opens or closes, and switch control is carried out in the load of any kind of light source and non-light source, thus realize multiple illuminating effect control with the system remote monitoring, manage.

Described current detection circuit 5 is to install current transformer additional at each loop relay load end, through amplifier coil two ends induced voltage is amplified, and the A/D analog to digital converter of single-chip microcomputer 3 calculates the real-time current in each loop through induced voltage.Detect the loop real-time current and in time feed back to host computer on the one hand, monitor, the current maxima of each loop restriction can be provided with by the commissioning staff neatly on the other hand; When the loop load electric current surpasses the current maxima of restriction; Turn-off, the protection relay contact prolongs the relay life-span.

The state of opening and closing of described loop state indicator light 6 show circuits; Open in this loop of bright representative, goes out to represent this loop to turn-off, when the loop load electric current surpasses the current maxima of restriction; The warning of glimmering, this loop load electric current of prompting commissioning staff surpasses the current maxima of setting.
