Abstract

The invention relates to a cross-border reminding function of a cell phone text message automobile computer diagnostic instrument. According to the function, when the cross-border reminding function is started, a circular region is delimited by a cell phone text message automobile fault remote intelligent detection device with the current position as the center and the kilometers designated by a customer as the radius; when the automobile drives out of the region, the automobile owner will be reminded by the detection device through a text message. By means of the function, the automobile owner can be effectively helped to manage and limit the automobile to drive in a designated area, for example, the automobile can be limited to drive in a city or in an industrial park.

Description

Development in Vehicle On-Board Diagnostics instrument geofence

Technical field

The present invention relates to the geofence function for fault diagnosing apparatus for vehicle, is exactly in fact position based reminding, relates in particular to a kind of detection method that can be used for supporting architecture.

Background technology

Architecture is generally applied to cellphone subscriber, cellular base station positioning service is called again shift position service (LBS-Locat ion Based Service), it is the positional information (latitude and longitude coordinates) of obtaining mobile phone users by the network of telecommunications mobile operator (as GSM net), under the support of electronic map platform, for user provides a kind of value-added service of respective service, the dynamic position enquiring service that for example China Mobile's M-ZONE provides at present etc.

Know-why is the down-bound pilot frequency signal that mobile phone is measured different base station, obtain TOA (the Time of Arrival of different base station descending pilot frequency, due in), according to this measurement result and in conjunction with the coordinate of base station, generally adopt triangle formula algorithm for estimating, just can calculate the position of mobile phone.Actual location-estimation algorithm need to be considered the situation of location, many base stations (more than 3 or 3), and therefore algorithm wants complicated a lot.Generally speaking, the number of base stations of moving table measuring is more, and measuring accuracy is higher, and positioning performance improves more obvious.

Summary of the invention

Travel in order effectively to help car owner's management vehicle to be limited within the scope of appointed area, the invention provides a kind of mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function, not only can timing automatic detect the current position of vehicle by it, and in the time detecting that vehicle exceeds the position that client sets, can also inform that user plays reminding effect by note.

Main technical schemes of the present invention is: read current longitude and latitude by the timing of mobile phone short message vehicle failure long-distance intelligent pick-up unit by architecture, in the time finding vehicle over-boundary, will send to user mobile phone with note form.

A kind of mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function: the milimeter number arranging taking user is as reference value, mobile phone short message vehicle failure long-distance intelligent pick-up unit obtains when the residing position of vehicle in front from UNICOM or the mobile base station of setting by GSM network, calculate vehicle from starting the position of setting to the distance of the present residing position of vehicle by software, in the time that this distance is greater than the reference value that user sets, can send to user mobile phone reminding user with note form.

The milimeter number that described user arranges can arrange by the form of note according to user's request, can receive after arranging successfully successful message reply is set.

Described mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function can also need to be opened or close according to user.

Brief description of the drawings

Fig. 1 is described mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence functional schematic of the present invention;

Embodiment:

As shown in Figure 1, below by the introduction of the concrete using method to mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function provided by the invention, further illustrate the feature of this device:

Confirm vehicle diagnosis seat, start described device: described device is inserted on automobile OBD diagnose connector,

Realize being connected of described device and electric-control system, wait for described device search network

(1) (about 30 seconds), find network rear indicator light to light;

(2) if first use " mobile phone short message vehicle failure long-distance intelligent pick-up unit " needs user to bind the cell-phone number of oneself, binding method user uses mobile phone editing short message RG+ password (as: RG123456) to mobile phone short message vehicle failure long-distance intelligent pick-up unit SIM card, waits for described device reply binding success information.If need to change the phone number of binding, directly, again with new digit binding, former phone number ceases to be in force automatically;

(3) open geofence function, editing short message ES+ two digits (0-9), two digits (0-9) represents radius milimeter number, span: 03-99 kilometer.As send note " ES03 " to mobile phone short message vehicle failure long-distance intelligent pick-up unit, and represent to go out centered by current location when Vehicle Driving Cycle, taking 03 kilometer of region as radius, this device note is reminded car owner.As do not specified radius distance value, only send " ES ", give tacit consent to 05 kilometer for radius.

(4) close geofence function, send note " EC " to mobile phone short message vehicle failure long-distance intelligent pick-up unit, close geofence.Geofence is dispatched from the factory default setting for closing.

Claims

1. mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function, it is characterized in that centered by current location, the milimeter number of specifying taking client, as radius, delimited a border circular areas, in the time that Vehicle Driving Cycle goes out this region, send to user mobile phone in time with note form.

2. mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function according to claim 1, it is characterized in that finding in time cross the border and inform that the method for vehicle user is: timing positions the residing position of automobile, obtain the longitude and latitude of automobile present position, determine the distance of moving vehicle by calculating the difference of longitude and latitude, in the time finding that this distance is greater than the distance of client's setting, can send in user's mobile phone with note form.

3. mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function according to claim 2, is characterized in that timing positions the residing position of automobile, is to position by UNICOM or mobile base station.

4. according to the mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function described in claim 2 or 3, it is characterized in that geofence function can need to be opened or be closed by the form that sends note according to user.

5. mobile phone short message vehicle failure long-distance intelligent pick-up unit-geofence function according to claim 4, is characterized in that the scope of crossing the border can need to modify by sending the form of note according to user.
