Below in conjunction with accompanying drawing, embodiment two of the present utility model is described.
The utility model embodiment provides a kind of parking stall management method, in conjunction with parking space management system shown in Figure 1, uses the flow process of the method affirmation parking stall state as shown in Figure 2, comprising:
In this step, gateway receives the parking stall status data that geomagnetic sensor is collected.Described parking stall status data comprises node number and ground magnetic value, described node number unique identification one parking stall and the corresponding geomagnetic sensor thereof of the geomagnetic sensor that described parking stall is corresponding.
Generally speaking, the every 10s of geomagnetic sensor once gathers, and the node number of the ground magnetic value that will collect and this geomagnetic sensor composition parking stall status data is sent to gateway
In this step, at first from the standard value formation of presetting, find out the calibration value on this parking stall according to the node number in the state token of parking stall, the size of the parking threshold values of the ground magnetic value in the dead ship condition data and this calibration value being done poor, poor absolute value and presetting.Described parking threshold values is a difference that presets (difference of sensing data and its calibration value) reference value.Reduce the threshold values that stops, can increase system rate of false alarm (such as, close on the impact of stopping on this parking stall the parking stall and become large); Increase the parking threshold value, can make the sensitivity (impact of magnetic value is less over the ground such as, some car, and threshold value is larger if stop this moment, then can not produce parking information) of system.Can according to actual needs, such as parking stall size, geomagnetism detecting device susceptibility etc., set suitable parking threshold values.
When being, enter step 204 in judged result, when the determination result is NO, enter step 203.
Among the utility model embodiment, need to safeguard a standard value, as the reference that judges whether parking, at first, and initialization one primary standard value in the time of need to starting in system, this flow process comprises as shown in Figure 3:
Step 301, collect at least twice described parking stall without the parking stall status data under the car parked state by geomagnetic sensor;
Preferably, in this step gateway can be by the geomagnetic sensor collection repeatedly without the parking stall status data under the car parked state as sample, the parking stall status data of collecting can be temporary in the buffer area, with as the foundation of calculating the primary standard value.The parking stall status data of each geomagnetic sensor is preserved separately, and is preferred, can preserve 20 up-to-date parking stall status datas.
Step 302, ask described at least twice described parking stall in without the parking stall status data under the car parked state the mean value of magnetic value, with the initial alignment value of described mean value as described parking stall;
The node number of step 303, the described initial alignment value of storage and correspondence thereof is to the calibration value formation.
When detecting dead ship condition, can collect without the dead ship condition data under the car parked state, according to these dead ship condition data standard value is upgraded, idiographic flow comprises as shown in Figure 4:
Preferably, as sample, the parking stall status data of collecting can be temporary in the buffer area, so that subsequent calls is calculated standard value without the parking stall status data under the car parked state for gateway can gather geomagnetic sensor in this step ten times or 20 times.
The absolute value of step 403, the current demarcation value difference of more described mean value and described parking stall and the renewal calibration value threshold values that presets;
Upgrading the calibration value threshold values is the foundation that judges whether to need to upgrade calibration value.Upgrade fixed the getting of demarcation threshold values and increase, can make the sensitivity of system; Upgrade to demarcate threshold values and reduce, can increase system rate of false alarm (such as, close on the impact of stopping on this parking stall the parking stall and become large).Can according to actual needs, such as parking stall size, geomagnetism detecting device susceptibility etc., set suitable parking threshold values.
Need to prove, it is a lasting long-term process that calibration value upgrades, and need to follow the tracks of the geomagnetic sensor uploading data always, therefrom tells without the parking stall status data under the car parked state, just can judge whether to upgrade.The data of single can not affect calibration value.Certain is larger or less value once, when processing, is considered to burr one time, can ignore.
The each time parking stall status data of a geomagnetic sensor collection all is the reference value of calculating this parking stall calibration value, judges whether to upgrade according to these reference values.Preferably, when having new parking stall status data to be uploaded to gateway device, all need to do the judgement of once whether upgrading calibration value at every turn.
In step 301 and step 401, need to be according to calculating calibration value without the parking stall status data under the car parked state, the parking stall management method that the utility model embodiment provides, can also be in numerous parking stall status datas, filter out the parking stall status data when berthing without car, as the effective sample that calculates calibration value, its flow process comprises as shown in Figure 5:
The absolute value of the difference of step 501, double parking stall, the parking stall status data of seeking common ground;
This step is whether to stop to there being dead ship condition to change from nothing because occured for the variation of judging double parking stall status data, surpass a normal scope when changing, be that the absolute value of difference can not drop on the base state threshold values when interval, namely think to have burr, the parking stall status data need to be abandoned.Otherwise think that the parking stall status data is effective, can act on without the parking stall status data reservation under the car parked state.
Embodiment of the present utility model provides a kind of parking stall management method and system, comprise gateway device and at least one place the parking stall and with parking stall geomagnetic sensor one to one, described geomagnetic sensor has unique node number gateway and collects current parking stall status data by described geomagnetic sensor, described parking stall status data comprises node number and the ground magnetic value of the geomagnetic sensor that described parking stall is corresponding, described node number unique identification one parking stall and corresponding geomagnetic sensor thereof, judge that whether the absolute difference of calibration value on described parking stall status data and this parking stall is less than the parking threshold values that presets, in described absolute difference during greater than described parking position value, judging that described parking stall is current has car to berth, finish the collection of parking stall status data and the judgement of dead ship condition by gateway, judge dead ship condition by the ground magnetic value, saved the procedure links of judging the parking stall parking state, improve judgement efficient and accuracy, solved existing calibration value treatment scheme complicated, inefficient problem.
