Embodiment Construction
[0019] See figure 1 with figure 2 , figure 1 It is a structural schematic diagram of the monitoring system of the warehouse of the present invention, figure 2 yes figure 1 Schematic diagram of the circuit structure of the filter device and the safety grating. The warehouse monitoring system includes a cassette 11 , a transport device 12 , a safety grating 13 , a filtering device 14 and a controller 15 .
[0020] The cassette 11 is used for holding a display panel (not shown).
[0021] The transfer device 12 is used to transfer the cassette 11 to the storage (not shown), that is, the transfer device 12 transfers the cassette 11 to the process machine for processing, and the transfer device 12 continues to transfer the cassette 11 to the storage after the processing is completed . In this embodiment, the warehouse is used to store the cassettes 11 .
[0022] The safety grating 13 is arranged on the inlet end (not shown) of the channel of the transmission cassette 11, an...

The invention discloses a warehouse monitoring system. The system comprises a safe raster, a filtering device and a controller. The safe raster is arranged on inlet end of a channel transmitting a cartridge for detecting whether wrong operation is generated during the process when the cartridge is transmitted to a warehouse through transmission equipment and outputting abnormity signals when it is determined that the wrong operation is generated during the process when the cartridge is transmitted to the warehouse through the transmission equipment; the filtering device is connected with the safety raster for determining whether the duration of the abnormity signals is greater than preset time after the abnormity signals are obtained from the safety raster and outputting a first control instruction to the controller when it is determined that the duration of the abnormity signals is not greater than the preset time; and the controller is connected with the filtering device for controlling the transmission equipment to transmit the cartridge to the warehouse after obtaining the first control instruction from the filtering device. Through such a mode, the warehouse monitoring system can reduce the frequency of the transmission equipment stopping transmitting the cartridge to the warehouse due to the wrong operation of the safe raster.
Description
technical field [0001] The invention relates to the monitoring field, in particular to a storage monitoring system. Background technique [0002] In the automatic storage system, each process machine has 3-4 inlets and outlets, through which the transmission equipment can transfer the cassettes to the process machine for processing, and finally transfer the cassettes to the storage. Among them, a safety grating is installed before each entrance, and the grating signal of the safety grating is directly connected to the controller, and then the controller controls the transmission device to stop or continue to transmit the cassette to the storage. [0003] During the process of transporting the cassettes to the storage by the transmission equipment, when the staff mistakenly sends the cassettes into other entrances, or when the staff or objects block the safety grating, the controller will report the safety grating error and control the transmission equipment to stop at the sa...
