[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , support rods 5 are evenly and fixedly connected to the inner sides of the medical material storage box 1, and limited slots 4 are evenly provided on the inner sides of the medical material storage box 1 below the front end of the support rod 5, and the bottom ends of the support tray 201 are slidably connected to the top ends of the support rods 5 respectively. The spacing between the support devices 2 is determined according to the height of the medical resource items, and the corresponding support rods 5 are selected to place the support devices 2. The limiting plug rods 203 are movably inserted into the inner sides of the limiting slots 4, and the threaded rods 204 are pushed and pulled by external force. Temperature sensors 6 are symmetrically fixedly installed on both sides of the inner side of the medical material storage box 1, a PLC control box 7 is fixedly installed on the top of the medical material storage box 1, a wireless transmission module 8 is fixedly installed on the top of the PLC control box 7, and an air conditioner 13 is fixedly installed on the rear end of the medical material storage box 1.
[0029] A protective window 14 is fixedly installed at the rear end of the interior of the medical material storage box 1, and the output end of the air conditioner 13 is connected to the interior of the medical material storage box 1 through the protective window 14. The air conditioner 13 controls the temperature inside the medical material storage box 1, and four hydraulic shock-absorbing rods 11 are evenly and fixedly installed at the bottom end of the medical material storage box 1. Shock-absorbing springs 12 are nested on the outside of the hydraulic shock-absorbing rods 11. Mechanical operations or natural vibrations in the post-disaster area will cause the medical material storage box 1 to shake. At this time, the hydraulic shock-absorbing rods 11 and the shock-absorbing springs 12 exert a shock-absorbing effect on the medical material storage box 1 to reduce the vibration of the medical material storage box 1 and prevent it from tipping over. A first magnetic door strip 10 is fixedly installed at the front end of the medical material storage box 1, and a box door 9 is rotatably connected to the front end of the medical material storage box 1. The interior of the box door 9 is designed as a transparent hollow tempered glass, and a second magnetic door strip 15 is fixedly installed on the side of the box door 9 close to the medical material storage box 1. The medical material storage box 1 is sealed by magnetic attraction through the first magnetic door strip 10 and the second magnetic door strip 15.
[0030] The PLC control box 7 is electrically connected to the temperature sensor 6, the wireless transmission module 8, the air conditioner 13 and the signal transmitter 308 respectively, and the wireless transmission module 8 is connected to the control terminal of the post-disaster emergency command room by wireless signals.
[0031] Working principle: When in use, first set the control program and temperature threshold range for the PLC control box 7, then place the item label inside the label placement slot 303, and at the same time place the medical supplies inside the material holding box 310 of the corresponding specification, and then place the material holding box 310 containing the corresponding medical supplies inside the holding slot 301 according to the label, and pull the pull ring 305 away from the label placement slot 303 through external force. The movement of the pull ring 305 drives the push slide frame 304 to move, and at the same time, the push slide frame 304 squeezes the second spring 309 to contract, and then the material holding box 310 is placed on the inner side of the holding slot 301. After placement, the force applied to the pull ring 305 is removed. At this time, the second spring 309 extends and pushes the push slide frame 304 to move to close to the outside of the material holding box 310, and then the signal transmitter 308 is numbered through the PLC control box 7, and the number of the signal transmitter 308 is According to the label on the automatic feeding device 3, during use, the PLC control box 7 receives the temperature information transmitted by the temperature sensor 6 in real time. When the temperature exceeds the threshold range, the PLC control box 7 controls the air conditioner 13 to start, and the output end of the air conditioner 13 adjusts the temperature of the inside of the medical material storage box 1 until the temperature inside the medical material storage box 1 is within the predetermined threshold range. The user can observe the medical materials contained in the medical material storage box 1 through the transparent glass on the door 9 and take them as needed. When taking the materials, the door 9 is opened by external force, and then the material holding box 310 containing the corresponding materials is selected and pulled upward by external force until the material holding box 310 is completely separated from the inner side of the holding groove 301. After the material holding box 310 at the front end is taken out, the second spring 309 extends to push the push slide frame 304 to move toward the front end and push the material holding box 310 to move forward to fit each other.
[0032] When all the material holding boxes 310 in the holding slot 301 are taken out, the push slide frame 304 moves to the inner front end of the holding slot 301. At this time, the push slide frame 304 drives the synchronous moving plate 306 to move to the front end of the holding slot 301. The synchronous moving plate 306 drives the moving magnet 307 to move to the outside of the signal transmitter 308. At this time, the signal transmitter 308 and the moving magnet 307 are magnetically connected. The signal transmitter 308 transmits the connection signal to the PLC control box 7. The PLC control box 7 transmits the signal to the control terminal of the post-disaster emergency command room through the wireless transmission module 8. The command room staff instructs the logistics staff to replenish the medical supplies according to the received information.
[0033] When the automatic feeding device 3 is damaged and needs to be replaced, the auxiliary pressure plate 205 is pressed downward by external force, and the movement of the auxiliary pressure plate 205 drives the telescopic baffle 202 to move downward to squeeze the first spring 207 to contract. When the telescopic baffle 202 moves to the point where the top of the telescopic baffle 202 is level with the bottom of the engaging groove 209, the containing groove 301 is pulled forward by external force, and the movement of the containing groove 301 drives the engaging rod 311 to disengage from the engaging slot 211. Then the automatic feeding device 3 is removed and a new automatic feeding device 3 is placed on the inner side of the engaging groove 209. Press and push the receiving groove 301, and the bottom end of the receiving groove 301 squeezes the telescopic baffle 202 and moves downward until the top of the telescopic baffle 202 is flush with the bottom end of the locking groove 209. At the same time, the first spring 207 is squeezed and contracted by the telescopic baffle 202, and the moving receiving groove 301 drives the locking rod 311 to be completely inserted into the locking slot 211. At this time, the bottom end of the receiving groove 301 is separated from the top of the telescopic baffle 202, and the first spring 207 loses pressure and stretches to push the telescopic baffle 202 to move upward until the top of the telescopic baffle 202 is close to the bottom end of the fixed plate 208.
