Abstract
The utility model provides a warning alarm, wherein a main transreceiver comprises a second Zigbee chip which is connected with an antenna ANT2 through an antenna matching network MN2 and a switch SW2, and is also connected with a buzzer SP; an auxiliary transreceiver comprises a first chip Zigbee which is connected with an antenna ANT1 through an antennal matching network MN1 and a switch SW1; the antenna ANT1 and the antennal ANT2 are communicated through wireless RF signals. When an owner is at a certain distance to a monitored object, a receiver carried along with the owner sends out a warning signal to remind the owner. The utility model is characterized by high accuracy, small power consumption and economical and practical properties.
Description
Technical field the utility model relates to a kind of reminding alarm device, specifically, be a kind of realize being subjected to monitored object away from or the isolated plant of warning reminding during near owner's setpoint distance.
The existing reminding alarm device of background technology, the simple transceiver of most uses because its frequency is subjected to the influence of circuit stability and environment, can often occur reporting by mistake.Another kind is used for the device that gun are reported to the police from body, only is applicable to metal.In addition, the most discrete devices that use of existing separation reminding alarm device realize that power consumption is big, and volume is big, and is economical and practical inadequately.
Utility model content technical problem to be solved in the utility model is, a kind of accuracy height is provided, and power consumption is little, economical and practical reminding alarm device, when transmitter and receiver leave or near to certain apart from the time, send the reminding alarm signal automatically.
The technical solution of the utility model is as follows:
A kind of reminding alarm device, comprise main transceiver and secondary transceiver, it is characterized in that: main transceiver comprises the 2nd Zigbee chip, and the 2nd Zigbee chip is connected antenna ANT2 by antenna matching network MN2 with switch SW 2, and the 2nd Zigbee chip also is connected with hummer SP; Secondary transceiver comprises a Zigbee chip, and a Zigbee chip is connected antenna ANT1 by antenna matching network MN1 with switch SW 1; Connect by radio-frequency signal between antenna ANT1 and the antenna ANT2.

The utlity model has following good effect: when the owner be subjected to monitored object leave certain apart from the time, be carried at owner's receiver on one's body and just send alerting signal, remind the owner.Have the accuracy height, power consumption is little, economical and practical characteristics.In the middle of practical application, the owner carries receiver, and transmitter then is installed on the object of being monitored, such as, handbag, mobile phone, children, or the like.
But this reminding alarm device is applied in reverse also, promptly when the object distance owner who is monitored less than set apart from the time, the reminding alarm device then sends the reminding alarm signal.
Description of drawings Fig. 1 is the circuit diagram of secondary transceiver.
Fig. 2 is the circuit diagram of main transceiver.
Each reminding alarm device of embodiment is made up of a pair of main transceiver and secondary transceiver.Be contained in secondary transceiver (as Fig. 1) on the controll plant to be emitted as the master.The main transceiver (as Fig. 2) that the owner held is then to be received as the master.Each transceiver has the identification code of oneself, so that be different from other transceiver.Physical circuit can be changed slightly according to the difference of selected transceiver chip.
The operation of reminding alarm device is controlled by the microcontroller software in the transceiver.The secondary transceiver that is installed on the controll plant produces radiofrequency signal through antenna matching network MN1, switch SW 1, by antenna ANT1, regularly or send continuously.Switch SW 1 is controlled by a Zigbee chip ZBT1, changes between reception and emission function on demand.Antenna matching network MN1 is made up of passive element, is used to reach the best power coupling of antenna ANT1 and radiating circuit.
When being installed in owner's main transceiver on one's body in range of receiving the time, receive the signal that secondary transceiver sends by a Zigbee chip ZBT2 by antenna ANT2, switch SW 2 and antenna matching network MN2, with signal decoding, obtain identification code.When identification be with own corresponding secondary transceiver after, still in range of receiving, main transceiver does not send any signal to the secondary transceiver that proves controll plant, but still is in accepting state.At this moment, if desired, receiver can send signal and pass through resistance R
1, driven for emitting lights diode (LED) 1, luminous prompting owner represents that monitored object still is in the scope that sets.Range of receiving can be set according to the emissive power of transmitter and the sensitivity of receiver.
When secondary transceiver was not in range of receiving, main transceiver did not receive the signal and the identification code of transmitter.Conclude that then secondary transceiver not in the scope of setting, so just pass through hummer SP and LED 2, sends alerting signal, remind to the owner.At this moment, receiver sends two drive signals, and wherein, a signal passes through resistance R
2, 2 work of driven for emitting lights diode (LED), another signal is through overdrive circuit excitation hummer SP work.Driving circuit is by resistance R
