Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1, the present invention discloses an elevator weighing device data sharing system 100, the elevator weighing device comprises a main control board 10, a weighing device controller 20 and a weighing sensor 30, the weighing sensor 30 detects weight data and transmits the weight data to the main control board 10 through the weighing device controller 20, and weighing parameters are stored in the main control board 10 and the weighing device controller 20; after the weighing device controller 20 is replaced, the main control board 10 transmits the weighing parameters to the weighing device controller 20 for storage; after the main control board 10 is replaced, the weighing device controller 20 transmits the weighing parameters to the main control board 10 for storage.

The whole elevator system also comprises a command input unit, a display unit and an alarm unit, and is used for performing man-machine interaction and alarm reminding.

Specifically, the main control board 10 detects whether the weighing device controller 20 is replaced, and if yes, the weighing parameters are transmitted to the weighing device controller 20 for storage; and detecting whether the main control board 10 is replaced, if so, transmitting a second weighing parameter transmission command to the weighing device controller 20, and receiving and storing the weighing parameters transmitted by the weighing device controller 20 by the main control board 10. The weighing device controller 20 receives and stores the weighing parameters transmitted by the main control board 10; and transmitting the weighing parameters to the main control board 10 according to a second weighing parameter transmitting command. The main control board 10 includes a detection circuit that detects whether the weighing device controller 20 is replaced and an output circuit that transmits a conveyance command to the weighing device controller 20. The weighing device controller 20 includes a receiving unit that receives the weighing parameter and the second weighing parameter delivery command, and an output unit that outputs the weighing parameter.

Preferably, the main control board 10 transmits the weighing parameters to the weighing device controller 20 for storage after the main control board 10 learns to obtain or update the weighing parameters; and/or the main control board 10 transmits the weighing parameters to the weighing device controller 20 for storage according to a first sharing command transmitted from the outside, and/or the main control board 10 transmits the weighing parameters to the weighing device controller 20 for storage after the weighing device controller 20 is replaced; and/or the main control board 10 detects whether the weighing device controller 20 stores weighing parameters, and if not, the weighing parameters are transmitted to the weighing device controller 20 for storage.

Preferably, the main control board 10 generates a second weighing parameter transmitting command, transmits the second weighing parameter transmitting command to the weighing device controller 20, and receives and stores the weighing parameter transmitted by the weighing device controller 20.

The main control board 10 self-checks whether the main control board 10 stores the weighing parameters, and if not, transmits a second weighing parameter transmission command to the weighing device controller 20; and/or the main control board 10 self-checks whether the main control board 10 is replaced, and if yes, transmits a second weighing parameter transmission command to the weighing device controller 20; and/or the main control board 10 transmits a second weighing parameter transmission command to the weighing device controller 20 according to an externally transmitted second shared command.

The main control board 10 outputs a main control weighing data replacement instruction to the output module after receiving the weighing parameters transmitted by the weighing device controller 20, receives an externally input instruction command, and stores the weighing parameters according to the instruction command. This embodiment may prevent the erroneous deletion of parameters in the system. For example, upon receiving the weighing parameters delivered by the weighing apparatus controller 20,

the weighing device controller 20 receives the weighing parameters transmitted by the main control board 10, outputs a weighing data replacement instruction of the weighing board to the output module, receives an externally input instruction command, and stores the weighing parameters according to the instruction command.

The main control board 10 detects whether the main control board 10 and the weighing device controller 20 store weighing parameters, and if any one of the main control board 10 and the weighing device does not have the weighing parameters, generates a corresponding alarm signal and transmits the alarm signal to an alarm unit. For example, if the weighing parameter in the main control board 10 is lost, an alarm signal indicating that the weighing parameter of the main control board 10 is lost is generated and transmitted to the alarm unit, so as to remind an operator that the weighing parameter of the main control board 10 is lost. If the weighing parameter of the weighing device controller 20 is lost, an alarm signal indicating that the weighing parameter of the weighing device controller 20 is lost is generated and transmitted to the alarm unit to remind an operator that the weighing parameter of the weighing device controller 20 is lost.

Of course, if any one of the main control board 10 and the weighing apparatus controller 20 does not have the weighing parameter, a corresponding first weighing parameter transmission command or a corresponding second weighing parameter transmission command may be generated, for example, if the weighing parameter of the main control board 10 is lost, a corresponding second weighing parameter transmission command may be generated and transmitted to the weighing apparatus controller 20, so as to receive and store the weighing parameter transmitted by the weighing apparatus controller 20. If the weighing parameters of the weighing device controller 20 are lost, a corresponding first weighing parameter conveying command is generated, and the weighing parameters are conveyed to the weighing device controller 20 for storage according to the first weighing parameter conveying command.

The above is used for realizing the automatic data sharing and storage after the main control board 10 and the weighing device controller 20 are replaced. When the main control board 10 and the weighing device controller 20 are not replaced, or when one weighing parameter of the main control board 10 and the weighing device controller 20 is lost or lacked, the normal running state of the elevator is locked, and after data sharing is completed, the normal running state of the elevator is released, so that the light load signal, the half load signal, the full load signal and the overload signal of the elevator can automatically and normally work.

Wherein, main control panel 10 and weighing device controller 20 communicate through the CANBUS, and main control panel 10 includes: detecting a CANBUS communication status between the main control board 10 and the weighing apparatus controller 20, and generating an overload signal when the CANBUS communication between the main control board 10 and the weighing apparatus controller 20 is interrupted. The main control board 10 of the utility model obtains weighing parameters and weighing acquisition signals of the weighing sensors through CAN communication.

Preferably, the weighing apparatus controller 20 detects weight data output by the weighing sensor, and transmits a sensor fault signal to the main control board 10 when the weight data is abnormal; the main control board 10 generates an overload signal according to the sensor fault signal.

Different from the above embodiment, in the second embodiment of the present invention, after the weighing apparatus controller 20 detects that the main control board 10 is replaced, the weighing parameters are transmitted to the main control board 10 for storage, and the weighing parameters transmitted by the main control board 10 are stored; after detecting that the weighing device controller 20 is replaced, the main control board 10 transmits the weighing parameters to the weighing device controller 20 for storage, and stores the weighing parameters transmitted by the weighing device controller 20.
