Abstract: La présente invention se rapporte à un procédé de contrôle d'accès amélioré pour des communications de type machine (MTC) dans un réseau 3GPP LTE avancé. Dans la solution technique décrite dans la présente invention, un dispositif MTC est configuré pour une interdiction d'accès améliorée (EAB). Quand le dispositif MTC tente d'accéder au réseau, la couche NAS vérifie si une EAB s'applique, ou non, à ce dispositif MTC. Dans l'affirmative, la couche NAS transfère la configuration EAB à la couche AS en vue d'un contrôle EAB supplémentaire. Sur la base de la configuration EAB, une station de base transmet des informations EAB à des UE, via un bloc d'informations système. Les informations EAB indiquent si une interdiction s'applique, ou non, à un nombre de catégories EAB et à un nombre de classes d'accès. Sur la base des informations EAB, les dispositifs MTC exécutent une EAB en rapport avec une tentative d'accès à la RRC. Si les informations EAB indiquent qu'une interdiction ne s'applique pas, le dispositif MTC exécute une ACB en rapport avec une tentative d'accès à la RRC.

Abstract: A salvaging-type water drainage and gas retrieval machine comprises a winch and power mechanism, a liquid sealant transmission mechanism, a machine frame and a drainage mechanism. The liquid sealant transmission mechanism seals a moving steel cable (104, 503) by the application of the principle of liquid sealing to avoid underground gas leakage and to achieve the transmission of the steel cable (104, 503) in the drainage and gas production process. The machine frame has a supporting effect, and can be adjusted to ascend and descend by means of the winch mechanism and accordingly facilitates underground equipment overhaul. The steel cable (104, 503) drives a water salvaging cylinder (411), which has a bottom-mounted check valve (414) and is arranged in the drainage mechanism, in an up-down reciprocating motion to salvage well liquid, and drains the well liquid to ground-level through a self-balancing check valve (413) arranged at the bottom of a drainage pipe (412), while at the same time effectively sealing off underground gases. Pressure within the coal reservoir is reduced and coal bed gases buried in the coal bed are continuously desorbed and collected. The present salvaging-type water drainage and gas production machine is simple in structure, convenient to be installed and maintained, small in investment, good effect in energy saving, free of wear sealing, high in reliability and long in service life, hence the machine is convenient to be intelligently controlled and is especially applicable to long-period and stable drainage and gas production of coal-bed gas wells.

Abstract: An AC permanent-magnet drain pump comprises a pump cap (1), a pump body (10), a magnetic core (15), a rotation shaft (11), a stator core (8), and a coil (7). The coil (7) winds on a coil former, the stator core (8) is assembled to the coil (7), and the pump body (10) is a case body integrally formed through injection molding and surrounding the contour of the coil (7), the coil former, and the stator core (8) that are assembled together. The case body defines an opening on the top and extends, through the opening, to a magnetic core accommodation space (10.1) for accommodating the magnetic core (15). A top opening of the magnetic core accommodation space is provided with a support structure for supporting the bearing of the rotation shaft. The pump body (10) comprises a first pump body portion (10a) and a second pump body portion (10b), and the inside of the second pump body portion (10b) is provided with a cylindrical rotor base (17) for supporting a rotor assembly. The magnetic core accommodation space (10.1) is encircled by the inner surface of the rotor base (17). An inwardly concaved arc portion of the stator core (8) is embedded in the rotor base (17). The AC permanent-magnet drain pump reduces a magnetic path air gap between the stator core (8) and the rotor, thereby improving the use efficiency of the product, reducing the structural size of the pump body, reducing the manufacturing cost of the product, preventing the pump body from resonating and making a noise, and enhancing the heat-dissipation performance of the pump.
