Kotlin融合位置提供程序多次获取位置更新

使用我的应用程序，我需要每3秒获取一次用户位置

这是我的代码：

class MainActivity : AppCompatActivity() {

    private lateinit var fusedLocationClient : FusedLocationProviderClient
    private lateinit var locationRequest : LocationRequest
    private lateinit var locationCallBack : LocationCallback

    private val  LOCATION_PERMISSION_ID = 999

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        updateUI()
        startLocationUpdates()

    }

    private fun updateUI() {
        fusedLocationClient = LocationServices.getFusedLocationProviderClient(this)
        locationRequest = LocationRequest.create().apply {
            interval = 3000
            fastestInterval = 3000
            priority = LocationRequest.PRIORITY_HIGH_ACCURACY

        }

    }

    private fun getLocationUpdates(){

            locationCallBack = object : LocationCallback() {
                override fun onLocationResult(locationResult: LocationResult) {
                    super.onLocationResult(locationResult)

                    println("=====" + locationResult.lastLocation.latitude)


                }
            }

    }

    private fun startLocationUpdates(){
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            LocationPermissionUtil.requestLocationPermission(this,LOCATION_PERMISSION_ID)
        }else{
            if(LocationPermissionUtil.isLocationEnabled(this)) {
                getLocationUpdates()
                fusedLocationClient.requestLocationUpdates(locationRequest, locationCallBack, Looper.getMainLooper())
                
            }else{
                LocationPermissionUtil.showGPSAlert(this)
            }
        }

    }

它工作正常，但我注意到应用程序每3秒获取位置5次

这是我的日志

这里怎么了？我需要它每3秒获取一次位置，然后将其发布到数据库
