Abstract: The present disclosure discloses a method and an apparatus for determining a leveling fault of an elevator. The method includes: acquiring a leveling signal and a target floor signal of an elevator, and determining whether the elevator is at a target floor according to the target floor signal; when yes, calculating a normal change sequence of signals of a leveling sensor of the elevator from a starting floor to the target floor; acquiring a real-time change sequence of the signals of the leveling sensor from the starting floor to the target floor; comparing whether the normal change sequence is the same as the real-time change sequence; and when the normal change sequence is the same as the real-time change sequence, determining that the elevator is normally leveled, and when the normal change sequence is different from the real-time change sequence, determining that the elevator has a leveling fault.

Abstract: A confined porphyrin Co(II), which is prepared by the following method: Equimolar amounts of aromatic aldehyde and pyrrole are condensed under acidic conditions to synthesize phenyl porphyrin compounds; the phenyl porphyrin compounds are metallized in a chloroform-methanol solution to obtain porphyrin Cu(II), which is brominated and demetallized to obtain confined porphyrin; the confined porphyrin is stirred and refluxed in a methanol solution for 12.0-24.0 h to obtain confined porphyrin Co(II). Its application is as follows: The confined porphyrin Co(II) is dissolved in cycloalkanes; the reaction system is sealed, and heated to 100 to 130° C. with stirring, to which oxygen is introduced to 0.2 to 3.0 MPa; the reaction is carried out for 3.0 to 24.0 h with stirring with the set temperature and oxygen pressure being maintained; and then the reaction solution is subjected to post-treatment to obtain the products.

Abstract: One example method includes obtaining, by an access network device, a waiting duration corresponding to transmitting uplink data of a first subframe quantity by a terminal, where the first subframe quantity is a subframe quantity with the greatest scheduling efficiency within a preset subframe quantity value range when the access network device schedules the terminal to transmit the uplink data. In response to determining that the waiting duration is greater than a threshold, the access network device can then determine a second subframe quantity that is within the preset subframe quantity value range and that enables the waiting duration to be less than or equal to the threshold. The access network device can then send a first uplink authorization instruction to the terminal, where the first uplink authorization instruction is used to instruct the terminal to send uplink data of the second subframe quantity.

Abstract: Embodiments of this application disclose an uplink transmission resource allocation method and apparatus. The uplink transmission resource allocation method and the apparatus may reduce resource fragments of an uplink transmission resource, increase an uplink peak rate of a cell, and improve spectrum utilization efficiency. The method may include: determining uplink data transmission grant instruction duration, first state transition duration, and duration of first uplink data transmission; and determining a target subcarrier based on the uplink data transmission grant instruction duration, the first state transition duration, and the duration of the first uplink data transmission, where the target subcarrier is an available subcarrier with a minimum difference between a start slot of uplink data transmission duration and an end slot of an allocated resource on an available subcarrier, and the available subcarrier is a subcarrier whose resource within the uplink data transmission duration is an idle resource.

Abstract: This application provides a downlink transmission resource allocation method and apparatus. The method includes determining a first time domain resource length and a second time domain resource length, and adjusting the second time domain resource length if the first time domain resource length is greater than or equal to a preset threshold. The method also includes if a third time domain resource length is greater than or equal to a decreased second time domain resource length, determining the first time domain resource length as a first target time domain resource length, and determining the decreased second time domain resource length as a second target time domain resource length. A first time domain resource is used to switch from a first state to a second state, a second time domain resource is used to receive the downlink data, and a third time domain resource is used to transmit the downlink data.
