Description

Continuous disconnection type wireless multipurpose device

Technical Field

The utility model relates to a wireless electron device technical field, in particular to wireless multi-purpose ware of continuous disconnection formula.

Background

The wireless electronic doorbell is a device used in many families, villas and other places, and as shown in fig. 1, the wireless electronic doorbell is divided into two parts: a transmitter and a receiver. The transmitter has a button which, when pressed, causes the receiver to emit an audible signal (optionally a ringing signal or a musical composition).

In order to overcome the monotonicity problem that the wireless electronic doorbell can only be used as a doorbell or a caller, the prior art discloses a technical scheme for developing a plurality of multipurpose products on the basis of the wireless electronic doorbell. Among them, chinese patent with publication number CN210093221U discloses a disconnected wireless multi-purpose device, as shown in fig. 2, which is composed of a wireless electronic doorbell (transmitter, receiver), a transistor, a resistor and a group of sensors. The disconnected wireless multipurpose device can be used for a plurality of application scenes such as wireless electronic doorbells, wireless beepers, water alarm, household appliance electric leakage tests, wireless temperature alarm and the like.

However, the above-mentioned prior art has the following disadvantages:

1. the wireless electronic doorbell works by pressing a button once, then the button of the doorbell is automatically disconnected, and the wireless electronic doorbell waits for the next button to be pressed for working again. That is, the button of the doorbell when the "disconnected wireless multi-purpose appliance" is used as an electronic doorbell or beeper is sufficient because it will automatically disconnect. However, if the sensor is used for operation, the sensor is required to be automatically short-circuited after being disconnected, otherwise, the next operation of the doorbell or the caller cannot be carried out.

2. Such problems are encountered when "disconnected wireless multiplexers" are used as water alarm: when water does not contact the sensor, the "disconnected wireless multiplexer" will send an audible signal warning that the water level has reached the sensor's position, but it cannot indicate whether this water level has changed, whether water is still leaving the sensor or has contacted the sensor.

3. When the disconnected wireless multi-purpose device is used for wireless anti-theft alarm, when the door and the window are opened, the magnetic suction switch or the voltage control switch is disconnected, the disconnected wireless multi-purpose device can send out a sound signal, but the disconnected wireless multi-purpose device cannot warn whether the door and the window are continuously opened or not.

SUMMERY OF THE UTILITY MODEL

It is emphasized that, in view of the above technical problems in the prior art, the present inventors made a contribution to finding out the reasons for the above technical problems: that is, the transmitter can be triggered only once by a signal generated by the external functional module, for example, when the external functional module is used for a water shortage alarm, a signal is sent to the transmitter once when the sensor leaves from the water along with the water level drop, and the signal is used for triggering the transmitter to send a wireless signal to the receiver once; however, after the transmitter transmits the wireless signal once, the water level changes, namely, the water level continues to drop, and the water level rises to enable the water to contact the sensor again, but since the wireless signal transmitted by the transmitter to the receiver is not triggered by the two changes, the user cannot continuously know the more detailed change of the water. In summary, the inventors have found that for the prior art "disconnected wireless multiplexer", the external functional module can only generate a signal in one case to trigger the transmitter to transmit a wireless signal to the receiver, resulting in less detail for monitoring data for various scene changes.

An object of the utility model is to solve one of the technical problem that exists among the prior art at least, provide a wireless multi-purpose ware of continuous disconnection formula, with scintillation emitting diode (BTS) and sending module, power module, trigger module establishes ties and forms the series circuit, utilize the change of scintillation emitting diode (BTS) electric current when the scintillation, the action of simulation button switch continuous uninterrupted switch-on and disconnection, thereby make the external function module of "wireless multi-purpose ware of disconnection formula" can produce multiple and many times signal under a condition and trigger the sender and send many times radio signal to the receiver, obtain the more careful data of various scene control.

Detailed Description

This section will describe in detail the embodiments of the present invention, preferred embodiments of the present invention are shown in the attached drawings, which are used to supplement the description of the text part of the specification with figures, so that one can intuitively and vividly understand each technical feature and the whole technical solution of the present invention, but they cannot be understood as the limitation of the protection scope of the present invention.

The inventor finds that for the disconnected wireless multiplexer in the prior art, the external functional module can only generate a signal to trigger the transmitter to transmit a wireless signal to the receiver in one case, so that the monitoring data is not fine enough for various scene changes.

The following provides embodiments of a continuously disconnected wireless multiplexer that can obtain more detailed data for various scene monitoring.

As shown in fig. 3, in an embodiment, a continuously disconnected wireless multiplexer is provided, which includes a wireless transponder, the wireless transponder has a prompt module, a power module, a trigger module, a sending module and a receiving module, the sending module and the receiving module are connected in a wireless communication manner, the power module, the trigger module and the sending module are connected in series to form a loop, the trigger module is disposed between a negative electrode of the power module and the sending module, and when the trigger module is triggered, the prompt module acts to send a prompt; the disconnected wireless multi-purpose device is also provided with a transistor (BG1), a resistor (R1) and an expansion interface, wherein the expansion interface is used for accessing an external functional module and comprises an expansion interface 1 and an expansion interface 2; one end of the resistor is connected between the trigger module and the power supply module, a collector of the transistor is connected between a connection point and the end of the resistor, the other end of the resistor is connected to a base electrode of the transistor, an expansion interface 2 is arranged at the end part of the base electrode of the transistor, an emitting electrode is connected between the trigger module and the sending module, and an expansion interface 1 is electrically connected with the emitting electrode of the transistor; the external functional module is equipment or a device which realizes corresponding functions by utilizing the disconnection of a passage; the wireless transponder is characterized by further comprising a flickering light emitting diode, wherein the flickering light emitting diode is connected in series in a loop formed by the power supply module, the triggering module and the sending module which are connected in series.

The continuous disconnection type wireless multiplexer is obtained by adding two flashing light emitting diodes (BTS) to the "disconnection type wireless multiplexer" disclosed in the background art. A blinking light emitting diode (BTS) is an opto-electronic integrated device that is fabricated by applying CMOS-LED technology to the light emitting diode. The appearance of the flashing light emitting diode (BTS) is not different from that of the common light emitting diode, but the BTS is composed of an Integrated Circuit (IC) and a light emitting diode in a tube shell, wherein the integrated circuit is composed of an oscillator, a frequency divider and a buffer driver. The oscillator generates an oscillation frequency f. The signal of (2) can obtain a certain fixed frequency fBL within the range of 1.3-5.2HZ after multi-stage frequency division, and then the buffer driving circuit is used for carrying out current amplification to output enough current to enable the flicker light-emitting diode (BTS) to emit light.

To increase operational reliability, in one embodiment, the continuously-disconnected wireless multiplexer employs a scheme in which two flashing light emitting diodes (BTSs) are connected in series. Although the current of the flashing light-emitting diode (BTS) can not be reduced to zero when the light-emitting diode does not emit light, the oscillator and the buffer driving circuit in the flashing light-emitting diode (BTS) still need to consume electricity when working, so the current flowing through the flashing light-emitting diode (BTS) is very different when the light-emitting diode emits light and when the light-emitting diode does not emit light, and the change of the current can play a role that the button switch is continuously and successively switched on and off. For the convenience of understanding, the invention point of the present invention is that "continuously disconnected wireless multiplexer" is compared with "disconnected wireless multiplexer" as shown in table 1.

TABLE 1

As shown in fig. 3, in one embodiment, a continuous break wireless multiplexer is provided that comprises a wireless electronic doorbell (transmitter, receiver), a transistor, a resistor, two self-flashing light emitting diodes (i.e., flashing light emitting diodes (BTS)), and a set of sensors. It can be used as:

1. wireless electronic doorbell

When the button of the doorbell is pressed or the sensor is disconnected, the transmitter of the electronic doorbell sends out a wireless signal, and the signal is received by the receiver of the electronic doorbell to trigger the sending of an optional sound signal or music. If the button is pressed continuously or the sensor is disconnected continuously, the wireless electronic doorbell can send out a sound signal or music continuously.

2. Wireless calling device

When the doorbell button is pressed or the sensor is disconnected, the receiver of the electronic doorbell sends out a sound signal or melody as a wireless call. If the button is pressed continuously or the sensor is disconnected continuously, the receiver of the wireless electronic doorbell can send out a sound signal or music continuously as a wireless call.

3. Water regime alarm

When the input end of the continuous disconnection type wireless multiplexer is connected with a water condition sensor (which can be a pair of electrodes or a pair of wires), the continuous disconnection type wireless multiplexer can send out an acoustic signal as soon as water leaves the sensor. If the water is not contacted with the sensor all the time, the continuously disconnected wireless multi-purpose device can continuously send out sound signals again and again. In this case, the "disconnected wireless multi-purpose device" only sends out the sound signal once, but cannot continuously send out the sound signal again and again. The function of the continuously disconnected wireless multiplexer provided by the present embodiment can be used as:

3.1 wireless alarm and wireless water level indication of flood control water level;

3.2 wireless water shortage alarm of pool, water tank, swimming pool, etc.;

3.3 wireless alarm of tap water cut-off;

3.4 wireless rain-stopping alarm after raining;

3.5 wireless water-return alarm for basement, manhole, house, parking lot, etc.

4. The test function 'continuous disconnection type wireless multi-purpose device' can be used as follows when being matched with a test meter pen:

4.1 Wireless lead on-off test

Two meter pens connected to the input port are used for contacting two ends of the conducting wire, and if the receiver of the continuously disconnected wireless multipurpose device gives out sound, the conducting wire is disconnected; no sound indicates that the wire is through.

4.2 Wireless diode Positive and negative electrode judgment

When the stylus is used to contact both poles of the diode, the continuously disconnected wireless multi-purpose receiver emits sound to indicate that the contact input end 2 is the negative pole of the diode and the contact input end 1 is the positive pole of the diode.

4.3 the household electrical appliance leakage test contacts the metal shell and the power plug of the household electrical appliance by two meter pens which are connected with the input port, and if the continuous disconnection type wireless multi-purpose device receiver sends out sound, the household electrical appliance is indicated to be leakage-free; no sound indicates electrical leakage from the appliance.

5. Wireless anti-theft alarm

The anti-theft alarm of doors and windows can be realized by using a magnetic suction switch or a pressure control switch connected to an input end. When the door and window is opened, the switch is turned off, and the continuously disconnected wireless multi-purpose device can send out an audible alarm signal. This warning signal does not disappear as long as the door or window is still open.

The work of the continuous disconnection type wireless multipurpose device is to control the power supply of the sending part of the wireless electronic doorbell to be switched on and off through the triode BG 1. The triode BG1 conducts the power supply to be switched on, and the sending part works; the transistor BG1 cuts off the power supply and the sending part does not work. The transistor BG1 is turned on and off by its upper and lower bias resistors. In order to ensure the normal operation of the continuously disconnected wireless multi-purpose device, the size of the upper bias resistor requires that the transistor BG1 is in a conducting state when the external resistor is disconnected (the lower bias resistor is infinite), and the conduction and the cut-off of the transistor BG1 are controlled by the lower bias resistor. The lower bias resistor is an external resistor at the input ports 1 and 2. The size of the external resistor depends on the use object of the continuous disconnection type wireless multi-purpose device:

1. when the water alarm device is used for water alarm, the external resistor is a water resistor, and the resistance of common water is more than ten kilo-ohms to hundreds of kilo-ohms (about 25 kilo-ohms for filtering tap water, about 40 kilo-ohms for farmer spring, about 520 kilo-ohms for Yibao water and about 17 kilo-ohms for tea water);

2. when the device is used for a diode test, the forward resistance of the silicon tube is about 5.2 kilo-ohms, the reverse resistance of the silicon tube is greater than 500 kilo-ohms, the forward resistance of the germanium tube is about 0.1 kilo-ohms, and the reverse resistance of the germanium tube is greater than 400 kilo-ohms;

3. the resistance of a wire when used for a wire on-off test is typically less than a few ohms;

4. when the magnetic switch or the voltage-controlled switch is used for anti-theft alarm, the contact resistance of the magnetic switch or the voltage-controlled switch is less than one ohm;

5. the resistance between the metal casing and the power plug when used in the leakage test of household appliances depends on the degree of leakage. As long as the BG1 triode is ensured to be cut off and the wireless electronic doorbell sending part does not work when the external resistor is connected, the BG1 triode is conducted and the wireless electronic doorbell sending part works when the external resistor is not connected (the lower bias resistor is infinite). The continuous disconnection type wireless multi-purpose device can realize the purposes by utilizing the flash-off performance of the self-flash light-emitting diode.

The continuous disconnection type wireless multipurpose device provided by the embodiment can realize continuous wireless electronic doorbell, wireless beeper, wireless water alarm, wireless lead on-off judgment, wireless diode anode and cathode judgment, wireless household appliance leakage test and wireless anti-theft alarm by only adding one transistor, one resistor, two self-flashing light emitting diodes and one group of sensors on the basis of the wireless electronic doorbell. The appearance of the wireless doorbell plays a positive role in the diversification of the application of the wireless doorbell.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
