Description
Affiliated technical field
The utility model relates to the anti-lost parents-children alarms of wireless telecommunications warning device, particularly short-distance wireless.
Background technology
Existing wireless anti-theft technology is often at remote, the big article or the fixing anti theft design of article, its wireless transmit distance can reach several kms, to having relatively high expectations of emissive power, power supply, and the volume of R-T unit is bigger than normal, basically all fix, immovable, only have the single-point monitoring function, do not possess tracking function.
And prior art generally is the way that adopts with the wired link of valuables aspect the carry-on valuables of individual antitheft, when this line is reported to the police during by premeditated the cut-out; Perhaps adopt the sensitization technology, when article are exposed to technology such as will report to the police in the light.Its shortcoming and application limit are apparent in view, article of line supervision of wired antitheft mode, and underaction, the sensitization technology then is easy to generate wrong report.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiencies in the prior art and provides movably a kind of, has multi-point monitoring and following function, and small and exquisite sensitivity is energy-conservation and can make the anti-lost parents-children alarms of short-distance wireless of hommization profile.
The short-distance wireless warning device is exactly to rely on advanced wireless communication technique, for the anti-theft and anti-losing problem of the carry-on valuables of solution of flexibility and reliability proposes.Be characterized in that wireless communication distance is near, generally remain within 15 meters adjustable, the integrated level height, light, small and exquisite, power consumption is little.Purpose is for valuables being monitored within people's auditory visual scope the monitoring range that exceeds setting when valuables just sends alerting signal immediately, reminds the article holder to note.
The purpose of this utility model is achieved in that
The anti-lost parents-children alarms of a kind of short-distance wireless, this device is made up of the primary controller of built-in reception signal device and the sub-device of at least one built-in emission signal device.
---the switch 1 of described primary controller connects power circuit module 2, and power circuit module 2 is connected with radio receiving transmitting module 3, signal pre-processing module 4 and the Signal Separation identification module 5 of the central microprocessing unit 6 of adjustable distance, warning circuit module 8, display circuit module 7, built-in aerial respectively.
---the power module of described sub-device is respectively with radio receiving transmitting module, signal pre-processing module 4 and assist central microprocessing unit to be connected.
---be provided with the device that can adjust sub-device alarm distance in the described primary controller.
---described primary controller and sub-device all are provided with the audible alarm device.
The principle of work of the utility model machine tool is:
1. switch (Power) is a startup, and reset key presses the button, and system then enters duty, and when closing button, system then closes, and is in the low power consuming state; Can adjustable range when starting, parameters such as power and display screen, it links to each other with the power circuit module;
2. the power circuit module directly is subjected to Power by key control, for each functional module of the anti-lost parents-children alarms of short-distance wireless provides required direct current and alternating voltage; Required 2.7V～3.3V and the required 12V DC voltage of warning circuit module during as chip operation, and the power circuit module also provides the charging inlet that directly links to each other with the 220V alternating voltage;
3. the main function of radio receiving transmitting module has two:
1. the wireless signal that receives handset and sent is also sent into the pretreatment module of signal to it;
2. machine tool is sent to handset through the control command of being sent after the signal Processing;
Present radio receiving transmitting module can directly not need to encode, and directly send behind the frequency modulation, and the communication between each handset and the machine tool all independently carries out, and can not produce interference;
4. the pretreatment module of signal is that signal is amplified, filtering, remove processing such as noise, mainly be because wireless signal receives that in the process of transmission extraneous interference is very big, and it is very high to the parameter request of signal when carrying out digital processing, so pre-service must be carried out, then pretreated signal is sent into Signal Separation, identification module;
5. because the anti-lost parents-children alarms of our designed short-distance wireless is seven handsets of a machine tool control, and the signal transmitting and receiving between machine tool and each handset carries out synchronously, the branch that does not have priority, so machine tool receives that the processing that at first will carry out behind the signal is the Signal Separation of each handset and identification, send into 7 parallel input interfaces then and handle;
6. central microprocessor unit is the nucleus module of the anti-lost parents-children alarms of short-distance wireless, and its major responsibility is orderly between each module of coordination, and reasonably work mainly is to be controlled by software; The most important is to control in addition, regulates the distance setting value of this device;
7. display circuit module shows Signal Processing process and parameter setting with visual effect, embodies the human oriented design of the anti-lost parents-children alarms of short-distance wireless;
8. the warning circuit module is last unit of signal Processing, control by central microprocessing unit, it can send alarm sound (plurality of optional is such as can oneself recording the prompting alarm sound) or produce vibrations, is made up of power amplification circuit and hummer two parts.
Handset principle of work of the present utility model is:
1. the transceiver module of signal is corresponding with the transceiver module of machine tool, is responsible for transmitting/receiving wireless signal (annotate: handset is different with the transmitting-receiving frequency of handset);
2. the pretreatment module of signal is the same with the pretreatment module function of machine tool, also is will carry out necessary processing to signal to realize with the function that adapts to next step;
3. assisting the corresponding central microprocessing unit with machine tool of central microprocessing unit to say, mainly is that some parameter settings and the order request according to machine tool comes work;
4. this power circuit module is just fairly simple, mainly is made up of battery and simple peripheral circuit.
Outstanding progress of the present utility model and remarkable result are: can remind in 15 meters scopes and carry the valuables personage, multi-point monitoring and follow the tracks of the article lose, and the small and exquisite sensitivity of composite aircraft can be designed to the art up shape of hommization, are easy to carry or hidden.Being widely used of this device can monitor as mobile phone, wallet etc. the various valuables of carrying.For example master control set can be made key chain, tie clip, belt hook or be embedded among wrist-watch, the PDA, then embeds or adheres on mobile phone, the wallet from device.For example work as the head of a family and go out to go to the big place of flow of personnel, use this device and just can reach the effect that prevents children loss with the child of oneself.
