Below with reference to the accompanying drawings the positioning terminal and positioning service system of the utility model embodiment are described.
Fig. 1 is the external structure schematic diagram according to the positioning terminal of the utility model one embodiment;Fig. 2 is shown in Fig. 1 Positioning terminal a visual angle internal structure schematic diagram;Fig. 3 is the inside at another visual angle of positioning terminal shown in FIG. 1 Structure diagram;Fig. 4 is the structure diagram of the housing of positioning terminal shown in FIG. 1.
As shown in Figs 1-4, positioning terminal 01 provided in this embodiment, including:For being mounted on the housing on positioning body 2;The housing 2 is internally provided with light sensor 3;The housing 2 is internally provided with system component 7, wherein, the system Component 7 of uniting includes controller and the alarm for sending out alarm;The controller respectively with the light sensor 3, described Alarm connects, and whether the ambient light information for being acquired according to the light sensor 3 monitors the positioning terminal 01 from calmly It is removed in the main body of position, and the alarm is controlled to send out police when monitoring the positioning terminal 01 and being removed from the positioning body Report.
Specifically, positioning body can be understood as arbitrarily needing the equipment positioned, such as the equipment in Internet of Things.It is protecting Under the premise of card positioning body is connect with 2 reliability of housing, the connection mode of positioning body and housing 2 is unlimited, can be housing 2 It is fixedly mounted in the holding tank in positioning body.
Specifically, the present embodiment forms the dismantling-proof alarming group of positioning terminal using light sensor 3, controller, alarm Part, when positioning terminal 01 is removed from positioning body, ambient light information that controller is currently acquired according to light sensor 3 Determine that positioning terminal 01 is removed, and alarm is controlled to send out alarm to notify user in time from positioning body in time, it is real Now alarm tamper purpose, ensures the safety of positioning body, and the dismantling-proof alarming component of the present embodiment can not be returned compared to mechanical botton The phenomenon that position alarm, effectively improve reaction sensitivity of the positioning terminal 01 when being removed.
Wherein, alarm can be any form of alarm, and optionally, alarm is loud speaker or buzzer.Control Device can be micro-control unit (Microcontroller Unit, MCU), and micro-control unit performance is good, of low cost.In this reality It applies in example, alarm and controller can be integrated into system component 7.
Further, the inside of the housing 2 is additionally provided with range sensor 3;Correspondingly, the controller also with it is described Range sensor 3 connects, between the positioning terminal 01 detected according to the range sensor 3 and the positioning body Distance monitor whether the positioning terminal 01 removes from the positioning body, and monitoring the positioning terminal 01 from described The alarm is controlled to send out alarm when being removed on positioning body.
Specifically, the present embodiment forms the dismantling-proof alarming group of positioning terminal using range sensor 3, controller, alarm Part, when positioning terminal 01 is removed from positioning body, controller is according to the positioning terminal 01 that range sensor 3 detects and positioning The distance between main body determines that positioning terminal 01 is removed from positioning body in time, and alarm is controlled to send out alarm and is come in time Ground notifies user, realizes alarm tamper purpose, ensures the safety of positioning body, the dismantling-proof alarming component of the present embodiment is compared to machinery Formula button can not return alarming function the phenomenon that, effectively improve reaction sensitivity of the positioning terminal 01 when being removed.
It should be pointed out that light sensor and range sensor can be configured in positioning terminal 01 simultaneously, can also only match Put light sensor or range sensor.The dismantling-proof alarming of the positioning terminal 01 of light sensor and range sensor is configured simultaneously Performance is more superior.
It should be pointed out that it is light sensor and/or range sensor that the lower section of the window 1 in Fig. 1 is corresponding.One In the possible realization method of kind, slot structure is formed at the top of housing 2, there is slot structure enough installation spaces to accommodate light Sensor and/or range sensor, and can enable light sensor sense external environmental light and/or range sensor to External world's transmitting infrared ray and the extraneous infrared ray returned of reception.In alternatively possible realization method, housing 2 is transparent material Housing, in this way, the light sensor being arranged on inside housing 2 can also sense external environmental light and/or range sensor energy Outwardly transmitting infrared ray and the extraneous infrared ray returned of reception.
For current positioning terminal 01, influence each other between 01 internal component of positioning terminal, on the one hand by GPS (Global Positioning System, global positioning system) or the Big Dipper position antenna 4 and GSM (Global System For Mobile Communication, global system for mobile communications) 5 positions of antenna are nearer, and signal interferes with each other between the two, makes GPS or 4 receiving sensitivity of Beidou antenna are relatively low, receive GPS or Big Dipper signal capabilities are poor, lead to 01 positioning accuracy of positioning terminal It is relatively low, cause location-based service of its offer and data analysis undesirable, on the other hand, antenna causes internal system other assemblies Interference influences the integral working of positioning terminal 01.
Further, the present embodiment positioning terminal further includes:It is arranged at barriers 9, the GPS of the inside of the housing 2 Or Big Dipper positioning antenna 4, GSM antenna 5, receiver 6, power supply 8;Wherein, the GPS or the Big Dipper positioning antenna 4 with it is described GSM antenna 5 is oppositely arranged on the top of the barriers 9;The receiver 6, the system component 7, the power supply 8 are set Put between the GPS or Big Dipper positioning antenna 4 and GSM antenna 5 and be disposed on successively the top of the barriers 9.
Specifically, the spacing between GPS or Big Dipper positioning antenna 4 and the GSM antenna 5 is as large as possible, is produced meeting Under the premise of product require, the width that the spacing that GPS or the Big Dipper are positioned between antenna 4 and the GSM antenna 5 is baffler can be set Degree.
Power supply 8 in the present embodiment is used for providing power supply, such as to GPS or north to the other assemblies of positioning terminal 01 Bucket positioning antenna 4, GSM antenna 5, receiver 6 etc. provide power supply.It, can be in order to improve the water resistance of entire positioning terminal 01 Wireless charging coil 10 in the lower part of barriers 9 is set, while wireless charging interface is set on power supply 8, by wireless Charge coil 10 gives 8 inlet wire wireless charging of power supply.It is charged using wireless charging mode, without external charge is set to connect Mouth, the more conducively waterproofing design of positioning terminal 01, it is simple in structure, it is easy to produce and process.
In the present embodiment, the polarization of positioning terminal 01 is improved by the layout of 01 various components of optimum position terminal Energy.Specifically, the present embodiment is provided with a barriers 9 inside the 01 of positioning terminal, which can reduce antenna and positioning In terminal between other assemblies and between each component of positioning terminal (interference of the antenna to other assemblies can be such as reduced, also may be used Reduce interference of the power supply 8 to antenna) interference, so as to improve the performance of positioning terminal 01 and device sensitivity.Simultaneously will GPS or Big Dipper positioning antenna 4, GSM antenna 5 are oppositely arranged on the both sides of barriers 9, such GPS or Big Dipper positioning 4 He of antenna GSM antenna 5 is apart from each other in the inside of positioning terminal 01, avoids and interferes with each other between the two, improves GPS or Big Dipper positioning antenna 4 signal receptions improve signal receiving sensitivity and positioning accuracy.
