Abstract
The utility model provides a relay of state transmission can carry out through WIFI, the utility model relates to an electronic information transmits technical field, and it contains CPU, coil, power, WIFI module, normally open contact and normally closed contact, the power respectively with WIFI module, CPU and winding connection, CPU be connected with coil and WIFI module respectively, the coil be connected with normally open contact and normally closed contact respectively, solved the difficult problem of wiring through WIFI wireless transmission, let the relay possess the ability of judging by oneself simultaneously, realized that the cloud is automatic.
Description
Technical field
The utility model relates to electro-nic message transmissions technical field, is specifically related to a kind of relay that can be carried out state transfer by WIFI.
Background technology
Relay is a kind of electronic control device, it has control system (also known as input circuit) and by control system (also known as output loop), usually be applied in automatic control circuit, it is actually the one " automatic switch " going to control larger current with less electric current.Therefore play the effects such as automatic adjustment, safeguard protection, change-over circuit in circuit.
Electromagnetic relay is generally made up of iron core, coil, armature, contact reed etc.As long as add certain voltage at coil two ends, certain electric current will be flow through in coil, thus generation galvanomagnetic effect, the pulling force that armature will overcome return spring under the effect of electromagnetic attracting force is inhaled to iron core, thus the moving contact of band moving armature and fixed contact (normally opened contact) adhesive.When after coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return to original position at the reaction force of spring, and moving contact and original fixed contact (normally-closed contact) are discharged.Such adhesive, release, thus the object reaching conducting in circuit, cut-out.
Relay generally uses and coordinates forming control system together with PLC, DCS in automated system.Its state and control all need by wiring and coordinate practical function with PLC/DCS system.There is no autonomous control ability, more can not meet the requirement of transmission of wireless signals and terminal intelligent in cloud automated system.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, the relay that can be carried out state transfer by WIFI reasonable in design, easy to use, the difficult problem of wiring is solved by WIFI wireless transmission, allow relay possess the ability judged voluntarily simultaneously, achieve cloud automation.
For achieving the above object, the technical solution adopted in the utility model is: it comprises CPU, coil, power supply, WIFI module, normally opened contact and normally-closed contact, described power supply is connected with WIFI module, CPU and coil respectively, described CPU is connected with coil and WIFI module respectively, and described coil is connected with normally opened contact and normally-closed contact respectively.
Operation principle of the present utility model: when resting, normally-closed contact is in closure state, and an output is in conducting state; When normally opened contact is in off-state, No. two outputs are in no-output state, when input be coil two ends switch on power time, the armature of relay is pushed aside from normally-closed contact and is communicated with normally opened contact by coil produces electromagnetic field, so when coil two ends are energized, normally-closed contact will become disconnection from closed, and an output will be also no-output state from ON transitions, normally opened contact will be become closed from disconnection simultaneously, and No. two outputs also will become conducting state; Relay is by the monitoring to coil, just the operating state of relay can be judged, when operating state changes, up-to-date relay status is sent to WIFI data acquisition module by WIFI module by CPU, up-to-date relay status is sent to cloud data server by WIFI data acquisition module again, and user just can by the last state of cloud automated system control relay; Control command can be sent to cloud data server by WEB or mobile phone A PP by user, cloud data server is after receiving the instruction that user sends out, instruction can be sent to WIFI data acquisition module by the very first time, data are sent to corresponding WIFI relay by WIFI by WIFI data acquisition module after receiving the data, WIFI relay upon the reception of control signals, CPU can power to coil by control relay internal electric source, realizes the work of relay.
After adopting said structure, the utility model beneficial effect is: a kind of relay that can be carried out state transfer by WIFI described in the utility model, the difficult problem of wiring is solved by WIFI wireless transmission, allow relay possess the ability judged voluntarily simultaneously, achieve cloud automation, and it is simple to have structure, arrange rationally, the advantages such as cost of manufacture is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1, the technical scheme of this embodiment is: it comprises CPU1, coil 2, power supply 3, WIFI module 4, normally opened contact 5 and normally-closed contact 6, described power supply 3 is connected with WIFI module 4, CPU1 and coil 2 respectively, described CPU1 is connected with coil 2 and WIFI module 4 respectively, and described coil 2 is connected with normally opened contact 5 and normally-closed contact 6 respectively.
The operation principle of this embodiment: when resting, normally-closed contact 6 is in closure state, and No. one exports 8 and is in conducting state; When normally opened contact 5 is in off-state, No. two export 9 and are in no-output state, when input be coil 2 two ends switch on power time, coil 2 generates an electromagnetic field the armature of relay to push aside from normally-closed contact 6 and is communicated with normally opened contact 5, so when coil 2 two ends are energized, normally-closed contact 6 will become disconnection from closed, and No. one exports 8 will be also no-output state from ON transitions, normally opened contact 5 will be become closed from disconnection simultaneously, and No. two export 9 and also will become conducting state; Relay is by the monitoring to coil 2, just the operating state of relay can be judged, when operating state changes, up-to-date relay status is sent to WIFI data acquisition module 7 by WIFI module 4 by CPU1, up-to-date relay status is sent to cloud data server by WIFI data acquisition module 7 again, and user just can by the last state of cloud automated system control relay; Control command can be sent to cloud data server by WEB or mobile phone A PP by user, cloud data server is after receiving the instruction that user sends out, instruction can be sent to WIFI data acquisition module 7 by the very first time, data are sent to corresponding WIFI relay by WIFI module 4 by WIFI data acquisition module 7 after receiving the data, WIFI relay upon the reception of control signals, CPU1 can power to coil 2 by control relay internal electric source, realizes the work of relay.
After adopting said structure, this embodiment beneficial effect is a kind of relay that can be carried out state transfer by WIFI described in this embodiment, the difficult problem of wiring is solved by WIFI wireless transmission, allow relay possess the ability judged voluntarily simultaneously, achieve cloud automation, and it is simple to have structure, arrange rationally, the advantages such as cost of manufacture is low.
