Abstract
The utility model relates to a wireless remote control device of an alternating-current electromagnetic valve, which comprises an electromagnetic valve, a remote controller, a wireless decoder and a solid-state relay. The remote controller is provided with keys, key signals are outputted to a transmitting circuit in the remote controller and then transmitted, and the wireless decoder outputs the signals to the solid-state relay so as to drive the corresponding electromagnetic valve to actuate after receiving the signals. The remote controller and the wireless decoder are operated at 315M Hz and adopt a nine-bit address coding mode, thereby greatly strengthening interference of wireless remote control devices in the same frequency band. The solid-state relay is connected with the electromagnetic valve, the decoder is electrically insulated from the electromagnetic valve by aids of a built-in SSR photocoupler, and the problem that a mechanical contact relay generates high-voltage arcs is solved thoroughly. The wireless remote control device of an alternating-current electromagnetic valve has the advantages of simple circuits, safety and reliability.
Description
Technical field
The utility model relates to a kind of control gear, particularly a kind of alternating current electromagnetic valve beeper.
Background technique
Alternating current electromagnetic valve has the fast and characteristics easily of powering of switching speed, is widely used in sewage treatment, Chemical Manufacture, industrial automation control field.The special industry scene that should not enter for some personnel (such as chemical pollution, have source of radiation and dust etc.), how alternating current electromagnetic valve is carried out the problem that telecontrol is a fine solution of needs.In addition, alternating current electromagnetic valve at present more adopts the mechanical contact-type relay to control, and the high-voltage arc that the contact produces can be a kind of potential safety hazard.
Summary of the invention
The utility model is the problem that has potential safety hazard at present alternating current electromagnetic valve in particular surroundings control, a kind of alternating current electromagnetic valve beeper has been proposed, can in 500 meters scopes, unlatching and the closure to solenoid valve carry out reliable wireless remotecontrol, avoid mechanical contact to produce high-voltage arc simultaneously.
The technical solution of the utility model is: a kind of alternating current electromagnetic valve beeper, comprise solenoid valve, remote controller, wireless decoding device, solid-state relay, be equipped with button on the remote controller, push button signalling is to remote controller internal emission circuit, transmit, after the wireless decoding device received signal, output signal drives corresponding solenoid valve action to solid-state relay.
Described remote controller and wireless decoding device frequency of okperation are 315MHz, adopt 9 bit address coding.Described solid-state relay adopts the SSR48-15A model, and passes through the photo coupler electrical isolation between the solenoid valve.
The beneficial effects of the utility model are: the utility model alternating current electromagnetic valve beeper has succinct, the safe and reliable characteristics of circuit.
Description of drawings
Fig. 1 is the utility model alternating current electromagnetic valve beeper structural representation block diagram;
Fig. 2 is wireless decoding device and a solid-state relay connecting circuit block diagram in the utility model alternating current electromagnetic valve beeper.
Embodiment
Alternating current electromagnetic valve beeper structural representation block diagram as shown in Figure 1, device comprises remote controller, wireless decoding device, solid-state relay, solenoid valve, be equipped with button on the remote controller, push button signalling is to remote controller internal emission circuit, transmit, after the wireless decoding device received signal, output signal drives corresponding solenoid valve action to solid-state relay.3 button A are arranged on the remote controller, B, C, when the user pressed the A key, the wireless decoding device received corresponding remote signal, made solid-state relay 1 conducting, thus opens solenoid valve; When the user pressed the A key again, solid-state relay 1 cut out, and solenoid valve 1 also cuts out thereupon.Solenoid valve 2, the remote control process of solenoid valve 3 is similar to the above.Test shows that this device is safe and reliable.
The key of this device is: the connecting circuit design between wireless decoding device and the solid-state relay.Wireless decoding device and solid-state relay connecting circuit block diagram as shown in Figure 2,315MHz wireless decoding device add the filter capacitor C of 0.1uF by the block dry cell power supply of 9V between both positive and negative polarity.9 bit address encoders can generate 19863 different mailing addresses, in order to strengthen anti-interference.After radio-frequency (RF) receiving circuit receives remote control command, transmit it to decoder, decoder is put corresponding output port high again.D0 among the figure, D1, D2 are output port, respectively with the button A of remote controller end, B, C correspondence.With the D0 port is example, and when the user pressed A key on the remote controller, the D0 port was put height, and the D0 port is connected with LED by 330 ohm current-limiting resistance R, and LED light is lighted.Simultaneously, solid-state relay obtains the VDC of 3.3V from current-limiting resistance R two ends, make the output terminal conducting of solid-state relay, and solenoid valve is realized opening.In this device, solid-state relay adopts the SSR48-15A model.Its control end input voltage range: 3-32VDC, control electric current 5mA-25mA.Circuit shown in Figure 1 satisfies the SSR48-15A usage requirement fully.When the user pressed A key on the remote controller once more, the D0 port was put low, closed electromagnetic valve.
Alternating current electromagnetic valve beeper characteristics: remote controller and wireless decoding device work in 315MHz, and frequency range and emissive power thereof all satisfy the regulation of the radio communication control of " radio administration of the Ministry of Industry and Information Technology of the People's Republic of China (PRC) "; Can be the user 19683 kinds of different mailing addresses are provided.Be remote controller between the different user can general probability be about 20,000/.Improved interference greatly with the frequency range wireless remote controller; Employing has the 315MHz wireless decoding chip of data latch function, will reduce to minimum to the interference of 220V alternating electromagnetic valve coil; Adopt solid-state relay (SSR) to be connected with solenoid valve.Realize electrical isolation between decoder and the solenoid valve by SSR built in light electric coupler, thoroughly avoided the mechanical contact-type relay to produce the problem of high-voltage arc.
