Abstract
A goods or human loss preventive alarmer includes a host and a submachine. The host is the receiver while the submachine is the emitter. The host is formed from a transmitting/receiving circuit, a control circuit and an alarmer. The control circuit of the host is a single-chip microcomputer where a monitoring distance threshold and a time threshold are positioned in advance. The monitoring distance threshold is corresponding to the strength. The emitting device of the submachine is a micro-power RF chip which matches with the transmitting/receiving circuit of the host. A beeper is adopted as the alarmer. The alarmer controls the scope of loss by receiving threshold of the signal strength, and automatically gives alarm, with good effect, and is convenient to carry. The circuit is reliable and has low power consumption. Small and compacted button battery is adopted as the power supply of the device, which minimizes the size of the whole product, providing convenience for carrying, strong adaptability and wide scope of application, with low cost and high business value.
Description
Affiliated technical field
The utility model relates to a kind of family expenses warning device, specifically is anti-article lost or personnel missing alarm reminder.
Background technology
The various valuables, wallet, handbag and other movable objects that carry of people in public places, usually because some reason lose; Child, old man and amentia personnel's the incident of wandering away also often takes place.The generation of these incidents has brought a lot of worries for people's normal life, and particularly because monitoring personnel's inadvertent causes wandering away of child or old man, misery of bringing to family and pressure are very huge and can not bear.But, thereby in actual life, also there is not a kind of device that can effectively point out prevention or reduce this situation generation.
The utility model content
The purpose of this utility model provides the device of a kind of effective prevention article lost or personnel missing, this device can be when above-mentioned situation takes place timely alarm, the continuation development of break event is eliminated incident before producing disastrous effect.
The purpose of this utility model reaches like this: a kind of anti-article lost or personnel missing alarm reminder, it is characterized in that: prompting device comprises main frame and handset, main frame is a receiver, handset is a transmitter, main frame is by transmission circuit, three parts of control circuit and alarm device constitute, and handset is an emitter.The control circuit of described main frame is the monolithic controller, wherein sets in advance monitoring distance threshold value and time gate limit value, and the monitoring distance threshold value is corresponding with signal strength values.Handset is the emitter that the transmission circuit with main frame is complementary.
The emitter of handset is little power consumption RF chip that the transmission circuit with main frame is complementary.
Be provided with microstrip slot antenna and filtering circuit in the transmission circuit of main frame.The alarm device adopts hummer.
The utility model has the advantages that;
1, control the scope of losing, wander away by the threshold value of received signal intensity, and send alarm automatically, technique effect is good, and is easy to use.
2, circuit is simple, and power consumption is little, and the device power supply adopts the small and exquisite button cell of volume, and small product size is very little, is easy to carry, and applicability is strong, and usable range is wide.
3, cost is very low, has higher commercial value.

Fig. 3 is the circuit structure diagram of handset.
Embodiment
Accompanying drawing has provided an embodiment of the present utility model.
The basic design philosophy of this prompting device is the theory according to radio wave propagation and strength retrogression.When the intensity of known emission electric wave, the received-signal strength of receiving according to take over party's measurement estimates distance between the emission electric wave object distance take over party with this.For example, under desirable communication environments, the decay of intensity of radio wave and r
2Be inversely proportional to, wherein r is a propagation distance.Otherwise, the intensity by setting the emission electric wave and the receive threshold of receiving end, the range of control that we can setting device.
According to above-mentioned ultimate principle, this prompting device is made up of main frame and handset two parts.Handset is an emitter, has adopted the little power consumption RF chip of 2.5GHz frequency range of Chipcon, to the radio signal of main frame emission 2.5GHz constant intensity.Handset is placed on the article that need monitoring or wears on one's body the personnel that need be guarded in child, old man or amentia etc.The device power supply adopts the small and exquisite button cell of volume, and small product size is very for a short time carries or wear all very convenient.
The main frame band is on one's body monitoring or monitoring personnel.It is by transmission circuit, and three parts such as control circuit and alarm device constitute.Transmission circuit adopts the little power consumption RF chip of 2.5GHz frequency range of Chipcon, is used to receive the signal of handset and transmits control signal to control circuit, adds bandwidth-limited circuit simultaneously to improve reception.Control circuit adopts the PIC10F ultra low-power microcontroller.The alarm device adopts hummer.Input end at the little power consumption RF chip of the 2.5GHz of transmission circuit Chipcon frequency range is added with antenna, is connected and accepts the control of single-chip microcomputer between the output terminal of RF chip and PIC10F ultra low-power microcontroller by data bus.The alarm control signal of single-chip microcomputer directly outputs to the alarm device.
Main frame receives the handset signal through antenna, through behind the bandpass filtering, signal is delivered to the receiving port of ChipconRF receiving chip, detects signal intensity in sheet.The control single chip computer of main frame reads the signal condition register of Chipcon RF receiving chip at interval, reads the received signal intensity level, and handset signal strength values and the strength threshold value that receives compared, judges.When receiver is received enough big signal, when signal strength values was higher than the signal strength threshold value of setting, single-chip microcomputer stopped counting and zero clearing with the control time counter.Distance when between handset and main frame is gradually far away, the intensity of the handset signal that receives will weaken thereupon, when signal strength values is lower than the signal strength threshold value of setting, time counter in the single-chip microcomputer begins counting, when time of not receiving the sufficient intensity signal during overtime threshold value, timer overflows, and single-chip microcomputer output control signal allows buzzer siren produce the prompting alarm sound.Signal strength threshold value and the time gate limit value set, can main control system and handset between alarm distance and interval time, thereby monitor controlled article or personnel effectively.Distance that moves according to monitored article or children under guardianship person's scope of activities difference can be set different signal strength threshold values and time gate limit value.Promptly set different control circuit single-chip microcomputer triggering levels and estimate corresponding monitoring distance.Be used for guarding go out child or old man, the monitoring distance threshold value is set at 5～10 meters, and the time gate limit value is set at 10～30 seconds; Be used to prevent article lost, the monitoring distance threshold value of its setting is about 0.5～1.5 meter, and the time gate limit value is set at 2～5 seconds.
