Abstract

The invention discloses an anti-lost management device for a self-organizing team based on Zigbee technology, which comprises two parts: a master and slavers. According to the device, when the device is in use, an administrator holds the master, and the slavers are placed on managed persons or things in a one-to-one manner; each slaver has a respectively unique ID without interference; the device has an anti-lost mode, a calling mode and a roll-call mode; the anti-lost management function of one master to a plurality of slavers is achieved; and an individual can manage the team conveniently.

Description

The anti-management equipment of losing of a kind of collective of group certainly based on the Zigbee technology

Technical field:

The present invention relates to the anti-management equipment of losing of a kind of collective of group certainly based on the Zigbee technology, particularly a kind of a plurality of people or thing organized the technical scheme that collective's network chemoprevention is lost management equipment certainly.

Background technology:

Because in the actual life, when leading trip by the leader, personnel may wander away in some collectives of team (tourism, visit team); And in order to prevent that the personnel of team from losing often roll-call, call the roll to consume a large amount of time.Therefore, need a kind ofly to prevent that personnel from wandering away that express statistic personnel number at any time can in time be called out remote personnel's equipment again.This equipment also can be used for managing personal articles, and valuables or small article enforcement network chemoprevention that the individual easily loses are lost management, prevents loss, and the anti-product of losing that is relevant to personal belongings at present has only man-to-man anti-losing, and does not have a pair of a plurality of object to prevent losing as yet.

Summary of the invention:

Fundamental purpose of the present invention is to provide a kind of realization one-to-many people based on the Zigbee technology or the management equipment of thing, can prevent that people or the thing managed from losing.This equipment has anti-lose pattern, call model, roll-call pattern.Anti-when losing pattern when enabling, can be by arranging by the scope of activities of custodian or thing, when being surpassed setpoint distance by custodian or thing, the hand-held main frame of supvr and the alarm prompting that all can be sounded or shake by the slave that custodian or thing carry, and the main frame screen that the supvr holds can demonstrate the slave number information of having left setting range.When enabling call model, the supvr sends notification signal can for specific team member, the prompting team member, and notice makes it revert to the zone of action.When enabling the roll-call pattern, can call the roll to the individuality in the whole collective in set distance range, can demonstrate the number that do not arrive the individuality in the specified scope fast and each arrive numbering and other relevant informations of individuality.

To achieve these goals, solution of the present invention is: a kind of collective of group certainly network chemoprevention based on the Zigbee technology is lost management equipment and is comprised main frame and slave two parts.Main frame comprises antenna, LCD display, and the CC2430 chip module, power supply, keyboard, sound-producing device, shaking device, slave comprises antenna, LED light, CC2430 chip module, power supply, sound-producing device, shaking device.During use, the supvr hands main frame, and slave places on the people or thing who is managed.Wherein can realize a main frame to a plurality of slaves, the people that each is managed or thing carry a slave, and each slave has own unique ID, do not disturb mutually.

Use realizes communicating by letter of main frame and slave based on the wireless communication technology of Zigbee agreement, and estimates distance between the host and slave processors by the intensity of measuring-signal.We select for use the CC2430 chip as communication chip, adopt the comparatively simple of CC2430 picked up signal intensity level.CC2430 is built-in the register RSSI of an indicator signal intensity (Received Signal Strength Indicator), and the corresponding relation of its value and RF power input as shown in Figure 1.The park mode of CC2430 and the characteristic that is transformed into the ultrashort time of aggressive mode are particularly suitable for the application that requires battery life very long.

Connect the back and can calculate distance according to the value of RSSI when setting up between two nodes, wherein D is distance, and n is path loss exponent, the absolute value of the reception signal intensity when A is 1 meter of the distance represented with dBm.Although still can have certain error because of the different and interference of air themperature, humidity etc., these errors are negligible in this problem.Computing formula is

D＝10 ^{(|RSSI|-A)/10n}

The present invention has designed and has a kind ofly lost management equipment from organizing collective's network chemoprevention, adopts the ZigBee technology, has the characteristics of low cost, high precision, low energy consumption, and same terminal can manage a network, and extensibility is strong.

Specific embodiments:

This is organized collective's network chemoprevention certainly and loses management equipment and comprise two parts, and one is the host part that the supvr hands, and one is installed in the people that managed or the slave parts on the thing.The groundwork process of system is:

(1) the anti-pattern of losing of colony

After selection colony prevented losing pattern, main frame was searched for according to default ID formation, each effective ID is sent prevent losing instruction, postbacked signal after the slave of this ID correspondence is received, main frame does not receive return signal and just repeatedly attempts, and gives the alarm.Main frame calculates distance according to the signal intensity that receives, exceeds distance range if detect the slave of certain ID, give the alarm signal and remind slave automatically of main frame.

(2) individual call model

After selecting individual call model, the supvr can select the individual ID that will call out by button, and main frame sends call signal, connects with slave, finishes calling procedure.If main frame can't be received the return signal of slave, just postback out alarm, and demonstrate the details of this ID individuality.

(3) colony's roll-call pattern

After selecting colony's roll-call pattern, main frame is according to the default ID formation operation of calling the roll, range of convergence is set after, the signal intensity of each slave calculates distance in the formation thereby detect respectively.If distance has surpassed range of convergence and namely has been labeled as, can be on the main frame LCD display directly the number of the individuality in the specified scope and each arrive numbering and other relevant informations of individuality in the Display Group.

Claims

1. the collective of group certainly network chemoprevention to a plurality of people or thing that is used for based on the Zigbee technology is lost management equipment, comprise a main frame and at least one slave two parts, it is characterized in that: described main frame comprises antenna, the CC2430 chip module, LCD display, power supply, keyboard, shell, sound-producing device, shaking device and each several part interconnect device; Described slave comprises antenna, LED light, and the CC2430 chip module, power supply, shell, sound-producing device, shaking device and each several part interconnect device; The hand-held main frame of supvr during use, slave places on the people or thing who is managed, and the people that each is managed or thing carry a slave, and each slave has own unique ID, do not disturb mutually; This equipment has to be prevented losing pattern, call model, roll-call pattern, can realize that a main frame is to the anti-management function of losing of a plurality of slaves.
