Abstract
Description
Technical Field
[0001] The utility model relates to a sensing device, in particular to a weight sensing device. Background Art
[0002] At present, in the drawers used to store test tube drugs in hospitals, the test tubes are simply inserted into the drawers for storage, and the specifications are uniform, which will inevitably increase the time cost when looking for a specific drug. Even if only one drug is stored in a drawer, there is a possibility that an empty test tube is stored in the drawer, which will also increase the time and cost of finding the drug. Utility Model Content
[0003] The utility model aims to provide a weight sensing device, which is installed at the bottom of a drawer and can solve the problem of increasing the time cost of finding medicines due to the existence of empty test tubes in the drawer.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A weight sensing device comprises a drawer board, a circuit board and a weight sensor. The circuit board is fixedly connected to the bottom of the drawer board, and a plurality of weight sensors are connected to the circuit board. A plurality of fixing positions are arranged on the drawer board, and the fixing positions correspond to the weight sensors one by one.
[0006] Furthermore, a processor is provided on the circuit board, and the processor is electrically connected to a plurality of indicator lights, which are fixed on the circuit board; each weight sensor is electrically connected to the processor, and the indicator lights correspond to the weight sensors one by one.
[0007] Furthermore, the circuit board is provided with a power plug connector, which is used to connect an external power source to supply power to the circuit board.
[0008] Furthermore, the model of the processor is STM32F103VET.
[0009] Furthermore, the fixing position has multiple sizes for placing items of different sizes.
[0010] Furthermore, the circuit board is provided with fixing holes, and the bottom of the drawer board is provided with connecting holes, and the fixing holes are connected with the connecting holes in a one-to-one correspondence.
[0011] Furthermore, the fixing position is circular, and the weight sensor is also circular and matches the fixing position.
[0012] Furthermore, the circuit board is rectangular.
[0013] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0014] The utility model adds a circuit board and a weight sensor at the bottom of the drawer board, and enters the weight of the empty test tube into the processor on the circuit board in advance. When the weight of the test tube stored in the drawer is greater than the weight of the empty test tube, the indicator light on the circuit board will light up, proving that there are drugs in the test tubes here, and there is no need to check whether there are drugs in each test tube, saving time and cost. The utility model saves time in searching for drugs and facilitates the recovery of empty test tubes in the drawer. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 The present invention is a cross-sectional view of a weight sensing device.
[0017] Figure 3 The figure is a block diagram of the connection between the processor, the indicator light and the weight sensor respectively. DETAILED DESCRIPTION
[0018] like Figures 1 to 3 As shown, a weight sensing device includes a drawer board 1, a circuit board 2 and a weight sensor 3. The circuit board 2 is fixedly connected to the bottom of the drawer board 1, and a plurality of weight sensors 3 are connected to the circuit board 2. The drawer board 1 is provided with a plurality of fixing positions 4, and the fixing positions 4 correspond to the weight sensors 3 one by one. The fixing positions 4 are used to fix the test tubes, so that the test tubes can be placed vertically in the drawer through the fixing positions 4. The weight sensor 3 is located at the bottom of the drawer board 1 and can sense the weight of the test tubes and medicines. The circuit board 2 is provided with a processor 5, and the processor 5 is electrically connected to a plurality of indicator lights 6 and can control the on and off of the indicator lights 6. The indicator lights 6 are fixed to the circuit board 2; each weight sensor 3 is electrically connected to the processor 5, and the indicator lights 6 correspond to the weight sensors 3 one by one. First, the weight of the empty test tube is entered into the processor 5 in advance. If there are medicines in the test tube, the test tube will transmit the signal to the processor 5 through the weight sensor 3, and the processor 5 will then transmit the command to light up the indicator lights 6. By observing the on and off of the indicator lights 6, it is judged whether there are still medicines in the test tube.
[0019] The circuit board 2 is provided with a power plug connector 7, which is used to connect an external power supply to power the circuit board 2. The model of the processor 5 is STM32F103VET. The fixing position 4 has multiple sizes for placing items of different sizes. At the same time, the weights of empty test tubes of different sizes are entered into the processor 5, which can also determine whether there are still medicines in the test tubes. The circuit board 2 is provided with a fixing hole 8, and the bottom of the drawer board 1 is provided with a connecting hole, and the fixing hole 8 is connected to the connecting hole one by one. The fixing position 4 is circular, and the weight sensor 3 is also circular and adapted to the fixing position 4. The circuit board 2 is rectangular.
