[0003] At present, there are two types of weighing and measuring methods for garbage cranes, automatic and manual. However, automatic measurement and manual measurement generally require human judgment and manual operation of the PLC controller to switch. Therefore, staff are required to monitor this on site. Not only automatic The level is low, and the waste incineration plant has a strong odor and many harmful substances, so it is not suitable for staff to stay for a long time

The invention relates to a weighing measurement method for a garbage derrick, which is applied to a weighing measurement system of the garbage derrick, The method comprises the following steps: (1) performing real-time acquiring of an operating state of a cart driving mechanism and a dolly driving mechanism, and position signals of a first position detecting device and a second position detectingdevice by a PLC controller; (2) automatically determining whether the corresponding position detecting device of the cart driving mechanism and the dolly driving mechanism can receive the position signal or not while driving by the PLC controller, if the result is positive, determining that the position detecting device works normally, and automatically entering an automatic metering mode, if theresult is negative, determining that the position detecting device has a fault, and automatically entering a manual metering mode. The weighing measurement method of the garbage derrick can automatically switch between automatic metering and manual metering without human judgment and operation.
Description
technical field [0001] The invention relates to the technical field of garbage cranes, in particular to a method for weighing and measuring garbage cranes. Background technique [0002] The garbage crane is the core equipment of the garbage feeding system of the municipal solid waste incineration plant. It is generally located above the garbage storage pool, and is mainly responsible for feeding, transporting, mixing, picking and weighing of garbage. Existing garbage cranes generally include a cart driving mechanism, a trolley traveling mechanism, a grab bucket, and a grab lifting mechanism. A weighing and measuring module is installed on the trolley traveling mechanism, and the weighing and measuring module includes a main control module, And a load cell and a communication module electrically connected to the main control module, the main control module can communicate with the PLC controller on site through the communication module, and the PLC controller can carry out th...
