Referring to fig. 1, fig. 1 is a schematic flow chart of a weighing and counting method for a medical cabinet according to an embodiment of the present invention;
a weighing and counting method of a medical cabinet comprises a weighing device and a cabinet door position detection device, and the weighing and counting method comprises steps S101-S102.
S101, when the detection device detects that the cabinet door is located at the first position, the weighing device acquires the real-time weight value of the medicine in the medical cabinet at regular time and updates the real-time weight value into an initial weight value.
S102, when the detection device detects that the cabinet door is located at the second position, the weighing device obtains the current weight value of the medicines in the medical cabinet, and the medicines in the medical cabinet are counted according to the current weight value and the initial weight value.
In this embodiment, medical cabinet is used for accessing the medicine, weigh when weighing device is used for medicine in the medical cabinet, detection device is used for detecting the position of cabinet door, be closure state when the cabinet door is located the first position, when the cabinet door is closure state, weighing device adopts regularly to acquire the real-time weight value of medicine in the medical cabinet, and update to initial weight value, the real-time weight value of medicine in the medical cabinet of this embodiment only regularly acquireing is updated to initial weight value, and need not be used for counting the renewal to medicine in the medical cabinet.
For open mode when the cabinet door is located the second position, can access the medicine in the medical cabinet this moment, the weighing device acquires the current weight value of medicine in the medical cabinet when the cabinet door is opened, obtain the change value of weighing according to current weight value and initial weight value, the change value of weighing at this moment only takes place in the short time, to a great extent has reduced the error that the influence of weighing device physical attribute and the environmental factor of weighing produced under the long-time closed condition of cabinet door, the change value of weighing that the event obtained is more accurate, it is also more accurate to count the renewal to medical cabinet traditional chinese medicine according to this change value of weighing.
To explain the principle of the weighing and counting method of the present invention, the accumulation of errors of the weighing apparatus will be briefly described below. Referring to fig. 4, the weight value measured by the weighing device fluctuates continuously if observed within a short time interval without changing the actual weight of the medicine detected by the weighing device; if observed over a longer time interval, the weight value measured by the weighing device tends to increase over time (the fluctuation increases). That is, in the long term, without changing the actual weight of the medicine detected by the weighing device, the error between the detection value of the weighing device and the actual weight value of the medicine gradually increases. When the error gradually increases and the error is accumulated to exceed the weight value of a single medicine, the counting result is changed even if the actual weight of the medicine is not changed (the medicine is not added), thereby causing a counting error.
Referring to fig. 5 as an example, in an initial state, no medicine is stored in the medical cabinet, and then a user (e.g., a drug manager) puts N1 medicines into the cabinet, wherein the weight of a single medicine is W0, and then closes the door to store the N1 medicines for a period of time; after a period of time, the user takes out N2 medicines (N1 is more than or equal to N2) from the medical cabinet. In fig. 5, the AB segment corresponds to the stage of putting N1 drugs, the BD segment corresponds to the stage of storing N1 drugs, the DG segment corresponds to the stage of taking N2 drugs, and the GH segment corresponds to the stage of storing (N1-N2) drugs. Furthermore, it should be noted that the lower graph in fig. 5 ignores the fluctuation of the weight value over a shorter time interval with respect to the upper graph in fig. 4.
Consider the case when N1 drugs are put in storage and N1 drugs are stored. The user opens the cabinet door first and places the medicine on the objective table in the medical cabinet. The user may place the drugs on the stage one by one or in batches, or alternatively, place the N1 drugs on the stage at one time. During the storage of the N1 medicines, the error value of the weighing device is accumulated, and if the storage time of the N1 medicines is long enough (e.g., hours, days), the error value of the weighing device is larger than W0. For example, as shown in fig. 5, when N1 medicines are initially stored, the weight value measured by the weighing device is W1, and after N1 medicines are stored for a certain period of time, the weight value measured by the weighing device is W2, and W2-W1> W0.
Therefore, for avoiding this condition, under the condition that the cabinet door was closed, weighing device's weighing device still weighed this N1 medicines, and the storage has an initial weight value in the control panel in the medical cabinet, and the initial weight value can be updated according to weighing device's measuring value in real time to the control panel, but the control panel does not carry out corresponding count operation. Assuming that the frequency of the A/D (analog/digital) values acquired by the weighing apparatus is 10Hz, the initial weight value in the control board is updated every 0.1s and is updated to the last weight value measured by the weighing apparatus. For example, from T1 to T2, the initial weight value is continuously updated from W1, and after a while, the initial weight value becomes W2. However, when the cabinet door is not opened, no matter which numerical value the initial weight value is updated to, the weighing device does not update the counting result, and the counting result is still the counting result before the door is closed last time.
Consider again the case of N2 drugs being taken. After N1 medicines are stored for a certain time, the user opens the cabinet door to take out the medicines. When the cabinet door is opened, the weighing device suspends updating the initial weight value (the initial weight value stays at W2); after the cabinet door is opened, the weighing device can weigh the medicines in the medical cabinet and count the medicines according to the medicine result. The weighing device can detect the current weight value of the medicine, the control panel can obtain a weighing change value by utilizing the difference between the current weight value and the initial weight value (the initial weight value is W2), and then the weighing change value is divided by the weight of the single medicine, so that a medicine quantity change value (which can be rounded) is obtained; then, on the basis of the counting result of the last door opening, a medicine quantity change value (the quantity change value is provided with a positive sign) is added to obtain a real-time counting result.
For example, if the counting result of the last door opening is N1 and the initial weight value of the door opening is W2, and the user takes a plurality of medicines, the current weight value is W3, the weighing change value is (W3-W2), and the number change value is Δ N, Δ N is (W3-W2)/W0, and the medicine counting result is updated from N1 to (N1+ Δ N). If the user takes a plurality of medicines again, the current weight value is changed into W4, the weight change value is (W4-W2), the Δ N is (W4-W2)/W0, and the medicine counting result is changed correspondingly.
After the medicines are taken out, the cabinet door can be closed, and then in the storage process of (N1-N2) medicines (and before the medicines are taken and placed next time), the weighing device only weighs and does not count, the initial weight value is continuously updated, but the medicine counting result is still the medicine counting result when the cabinet door is closed last time.
In summary, the weighing and counting method of the present invention determines the position of the cabinet door by the detection device, and determines the position state of the cabinet door by the different positions of the detection device, for example, determines whether the cabinet door is opened or closed to determine whether the user performs the operation of picking and placing the medicine, and then the weighing device is in different operation modes. When the cabinet door is at the first position, the user does not carry out the operation of getting and putting the medicine, and weighing device only updates the weighing result and does not update the count result, and when the cabinet door was at the second position, weighing device acquireed the current weight value of medicine in the medical cabinet to medicine is counted in the medical cabinet according to current weight value and initial weight value. Compare and weigh and count the medicine all the time, set up like this and can avoid long-time storage medicine and the counting error that leads to. The weighing and counting method can effectively reduce the counting error caused by the accumulation of the error, and has high counting accuracy.
