Description

Technical Field

[0001] This invention relates to the field of intelligent logistics tools, specifically to a smart hospital overhead rail logistics cart. Background Technology

[0002] Hospital logistics transport systems are specialized systems for the automated and rapid transfer of medical supplies within hospitals. They encompass various types, including pneumatic logistics systems, rail-based logistics systems, AGV (Automated Guided Vehicle) systems, and elevated monorail trolley systems. Pneumatic logistics systems use compressed air as power, with a maximum load capacity of 5 kg and a speed of 5-8 m / s. Rail-based systems utilize intelligent trolleys with a load capacity of 10-30 kg. AGV systems achieve material transport through a central control system, with a maximum speed of 1 m / s. These systems can transport medicines, specimens, medical waste, and other items, reducing labor costs and improving transport efficiency.

[0003] A rail-based logistics transport system refers to a system that uses intelligent rail-mounted trolleys to transport goods on dedicated tracks under computer control. Rail-based logistics transport systems have been invented and applied for nearly forty years. Their main advantages include the ability to transport relatively heavy and large items, typically weighing 10-30 kg, making them advantageous for transporting hospital infusions, batches of laboratory specimens, and supplies from the central supply room. A rail-based logistics transport system generally consists of receiving and dispatching workstations, intelligent rail-mounted trolleys, logistics tracks, track switchers, automatic isolation doors, central control equipment, and a control network.

[0004] However, the current rail-mounted logistics carts used in hospitals have the following drawbacks: 1. When the logistics cart moves from the receiving and dispatching station to the top logistics track, it undergoes a bottom and top swapping process to complete the overhead track operation. To prevent the liquid specimens loaded in the logistics cart from shaking and spilling due to the upside-down movement of the material cart, the current practice is to install a gyroscope in the material cart to ensure that the specimen tube opening is always facing upwards. Although the gyroscope solves the problem of specimen oscillation and spillage caused by the upside-down movement of the test tubes, it occupies a large amount of space inside the logistics cart and reduces the effective load of the logistics cart; 2. When the current logistics track crosses a firewall, the blocking gate at the firewall lacks an automatic sensing and automatic opening mechanism. Often, the logistics cart needs to break through the blocking gate to pass. This method not only damages the logistics cart but also results in insufficient fire protection. Summary of the Invention

[0005] To address this, the present invention provides a smart hospital overhead rail-mounted logistics trolley. This trolley employs a three-section logistics track, meaning the receiving / dispatch station and the transport section are separated. A logistics box transfer mechanism is installed on each track section. Utilizing the clamping and transfer function of this mechanism, the logistics box is held at different positions, preventing it from being inverted. This eliminates the need for a gyroscope within the logistics box, thereby improving space utilization and load capacity. The trolley's track is equipped with automatic sensor doors that open or close as the trolley passes by. These doors remain closed when abnormal temperature or smoke concentration is detected, effectively isolating the fire.

[0006] To achieve the above-mentioned technical effects, the present invention is implemented through the following technical solution: The intelligent hospital overhead rail logistics trolley includes a dispatching work track, a receiving work track, a hoisting work track, a vertical connecting track, a logistics box transfer and clamping mechanism, and a logistics box. The dispatching and receiving work tracks are horizontally arranged, while the vertical connecting track is vertically arranged. A vertical connecting track is provided between the dispatching and hoisting work tracks, and between the receiving and hoisting work tracks. Each of the dispatching, receiving, hoisting, and vertical connecting tracks is equipped with a logistics box transfer and clamping mechanism. The logistics box has a rectangular box structure, and a pair of clamping slots are opened near the top, bottom, left, and right sides of the front and rear panels of the logistics box. The logistics box moves up, down, left, and right by clamping the corresponding clamping slots in the four directions, thereby achieving non-flipping transfer of the logistics box between the dispatching, receiving, hoisting, and vertical connecting tracks.

[0007] Furthermore, an automatic sensor switch fire door is installed above the firewall through which the hoisting work track passes. A fire door switch controller is fixed on the automatic sensor switch fire door. Fire detection sensors are installed on both sides of the automatic sensor switch fire door. A switch drive mechanism is fixed on one side of the automatic sensor switch fire door. Position contact switches for detecting the logistics box transfer clamping mechanism are fixed on the hoisting work track on both sides of the automatic sensor switch fire door. The contact switches, switch drive mechanism and fire detection sensors are all connected to the fire door switch controller.

[0008] Furthermore, the logistics box transfer clamping mechanism includes a self-propelled base. A pair of clamping plates are fixed to the top of the self-propelled base, and a pair of hydraulic clamping rods are fixed to the outer sides of the clamping plates. An infrared emitting sensor is fixed at the bottom center of one clamping plate, and an infrared receiving sensor is fixed at the corresponding position of the other clamping plate. The self-propelled base has a traveling groove, which engages with the dispatching working track, the receiving working track, the hoisting working track, and the vertical connecting track. The connecting track is an I-shaped track. A traveling wheel extends from the traveling groove of the self-propelled base and can rotate on the wing plate of the I-shaped track. The self-propelled base is hollow inside, and a traveling drive motor is fixed in the grooves on both sides of the self-propelled base. The traveling drive motor is fixedly connected to the traveling wheel via a rotating shaft. A rotating shaft through hole is opened in the groove wall. A transfer controller is fixed in the cavity of the self-propelled base. The hydraulic clamping rod, infrared emitting sensor, infrared receiving sensor, and traveling drive motor are all connected to the transfer controller.

[0009] Furthermore, the transfer controller includes a lid and a bottom plate. A first battery, a first control circuit board, and a first relay module are fixed on the bottom plate. Both the first battery and the first relay module are connected to the first control circuit board. The first control circuit board is equipped with a first processing chip, a first power module, a first analog-to-digital converter module, a first digital-to-analog converter module, a GPS module, a wireless communication module, and a constant current source drive module. The first battery is connected to the first processing chip via the first power module. An infrared emitting sensor is connected to the first processing chip via the constant current source drive module. The infrared receiving sensor is connected to the first processing chip via the first analog-to-digital converter module. The first relay module is connected to the first processing chip via the first digital-to-analog converter module. The GPS module and the wireless communication module are both connected to the first processing chip. The hydraulic clamping rod and the walking drive motor are connected to the first relay module. The transfer controller is connected to a remote control panel via the wireless communication module.

[0010] Furthermore, the automatic sensor-operated fire door includes a door frame and a rotating door leaf. A fire door switch controller is fixed to the top of the door frame, and a fire sensor, including a temperature sensor and a smoke sensor, is fixed to the fire door switch controller and the other side of the door frame. The rotating door leaf is hinged to the door frame via a hinge, and the switch drive mechanism is hinged to the rotating door leaf. The fire door switch controller includes a housing and a housing panel. The housing encapsulates a second battery, a second control circuit board, and a second relay module. The switch drive mechanism is connected to the second control circuit board via the second relay module, and the second battery is connected to the second control circuit board. The position contact switch includes a pair of reflective infrared sensors disposed on both sides of the automatic sensor-operated fire door, and the reflective infrared sensors are connected to the second control circuit board.

[0011] Furthermore, the switch drive mechanism includes a servo motor and a crankshaft connecting arm. A pull plate is fixed on the rotating shaft of the servo motor, and one end of the crankshaft connecting arm is hinged to the pull plate and the other end is vertically fixed to the rotating door leaf.

[0012] Furthermore, the remote control panel includes a display screen and operation buttons. The remote control panel is wirelessly connected to the logistics box transfer and clamping mechanism fixed on the sending work track, receiving work track, hoisting work track, and vertical connecting track via a wireless communication module.

[0013] The beneficial effects of this invention are as follows: The logistics trolley adopts a three-section logistics track, that is, the receiving and dispatching station and the transportation section are disconnected from the track. A logistics box transfer mechanism is set on each track section. The clamping and transfer function of the logistics box transfer mechanism is used to clamp the logistics box at different positions, which can avoid the logistics box from being upside down. There is no need to set a gyroscope rotation device in the logistics box, thereby improving the space utilization and load capacity of the logistics box. The logistics trolley track is equipped with an automatic sensor door, which can open or close when the logistics trolley passes by, and keep the fire door closed when abnormal temperature and smoke concentration are detected, thereby achieving the purpose of effectively isolating fire.

[0026] A specific application of this device is as follows: The logistics box 6 containing liquid specimen tubes is placed on the logistics box transfer and clamping mechanism 5 on the dispatching work track 1. The clamping slot on the logistics box 6 is aligned with the hydraulic clamping rod 53 and inserted. After insertion, the infrared light emitted by the infrared emitting sensor 54 is blocked, and the infrared receiving sensor 55 outputs a high level. Subsequently, the first processing chip receives the high-level signal and outputs a logistics box positioning signal to the wireless communication module. The wireless communication module transmits this signal to the remote control panel 13, and the corresponding signal indicator light on the dispatching control area of ​​the remote control panel illuminates. Pressing the clamping button on the remote control panel transmits the control signal to the dedicated logistics box clamping mechanism 5 on the dispatching work track. At this time, the hydraulic clamping rod extends and engages in the clamping slot of the logistics box to complete the clamping. Then, pressing the left or right shift button on the remote control panel continues until the clamping slot on the left side of the logistics box engages vertically. The logistics box is inserted into the dedicated clamping mechanism 5 of the connecting track and aligned with the hydraulic clamping rod. At this time, the signal indicator light in the corresponding area on the remote control panel will light up. Then, press the unlock button in the corresponding dispatch control area on the remote control panel and press the clamping button in the connecting transfer area. Press the up or down button on the remote control panel until the top side of the logistics box is inserted into the dedicated clamping mechanism 5 of the logistics box on the hoisting working track. After the clamping slot is aligned, the signal indicator light in the corresponding transfer control area on the remote control panel will light up. Then, press the unlock button in the connecting control area and press the clamping button in the transfer control area, and then press the transfer button. The logistics box will enter the receiving chamber. Then, the receiving personnel will operate the dedicated clamping mechanism 5 of the logistics box through the remote control panel to move the transfer box up and down and left and right to reach the operating area. During the entire transfer process, the logistics box does not flip over, so there will be no problem of flipping or shaking of the liquid specimen.

[0027] As the logistics box passes through the hoisting track, it will pass through position contact switches on both sides of the automatic induction switch fire door. The position contact switches use reflective infrared sensors. When the logistics box's special clamping mechanism 5 blocks the reflective infrared sensor, the fire door switch controller 9 fixed on the automatic induction switch fire door will receive the blocking feedback signal. When the feedback signal is received once, the fire door switch controller 9 will drive the switch drive mechanism to open the rotating door. When the feedback signal is received an even number of times, the fire door switch controller 9 will drive the switch drive mechanism to close the rotating door to facilitate the passage of the logistics box. When the fire sensor detects a fire, it will transmit the information to the fire door switch controller 9, which will then drive the switch drive mechanism to keep the rotating door closed.
