Referring now to fig. 1, an embodiment of the present invention will be described. It is to be understood that the following description is only exemplary of the present invention and is not intended to limit the present invention in any way.
As shown in FIG. 1, the embodiment of the invention provides a method for detecting the falling of a container. The falling detection method of the container comprises the following steps:
sending a synchronous electric signal to a signal receiving unit matched with the signal transmitting unit by the signal transmitting unit;
in response to receiving the synchronous electric signal, the signal receiving unit starts an infrared receiving end;
and the signal transmitting unit transmits the infrared detection signal to the infrared receiving end.
Under the normal condition, most of infrared falling goods detection devices are directly and simultaneously started by a transmitting end and a receiving end, and then the state of the receiving end is detected in a polling mode. However, in this period, the tube heads of the transmitting end and the receiving end interfere with each other, and the object falling cannot be detected. Therefore, in the method provided by the embodiment of the present invention, firstly, the signal transmitting unit sends out the synchronizing electrical signal to the signal receiving unit paired with the signal transmitting unit; when the signal receiving unit receives the synchronous electric signal, the signal receiving unit can start the infrared receiving end to receive the infrared detection signal. After the infrared receiving end is opened, the signal transmitting unit can transmit an infrared detection signal to the infrared receiving end so as to detect whether goods fall or not.
By the method, the infrared detection signals can be transmitted synchronously between the signal transmitting units and the signal receiving units which are matched with each other, and the situation that the infrared detection signals are received by other signal receiving units by mistake is avoided. By means of the arrangement, the synchronization and the correspondence of the received signals can be ensured, the one-to-one transmission/reception of the transmitting terminal and the receiving terminal can be ensured, and mutual interference is avoided, so that confusion and loss caused by false detection to users are reduced as much as possible.
It should be noted here that, for the signal transmitting unit and the signal receiving unit, the two units respectively have an infrared transmitting end and an infrared receiving end, and an infrared detection signal is transmitted between the infrared transmitting end and the infrared receiving end to detect whether the goods fall down. When the goods fell down, the goods can cut infrared detection signal, leads to infrared receiving terminal can't receive infrared detection signal, can judge this moment that the goods fell down.
In addition, the signal transmitting unit and the signal receiving unit also have a signal transmitting circuit and a signal receiving circuit, respectively, and are electrically connected to each other to perform transmission of an electric signal, that is, to perform the synchronization matching operation as described above and the self-checking operation to be described below using the electric signal. That is, the signal transmitting unit and the signal receiving unit simultaneously perform two operations of transmitting the infrared detection signal and transmitting the electric signal.
Further, in one embodiment, the container falling detection method may further include the steps of:
and respectively and sequentially executing the step of sending out the synchronous electric signals, the step of starting the infrared receiving end and the step of transmitting the infrared detection signals on the plurality of groups of signal transmitting units and signal receiving units which are matched with each other.
That is, in this embodiment, a plurality of sets of the signal transmitting unit and the signal receiving unit are included. For each group of signal transceiving unit groups, the signal transceiving unit groups respectively comprise a signal transmitting unit and a signal receiving unit which are paired and synchronous with each other, and the signal transmitting unit and the signal receiving unit are arranged in a one-to-one correspondence manner. When a user uses the container, each group of signal receiving and transmitting unit groups executes the step of sending out synchronous electric signals, the step of starting the infrared receiving end and the step of transmitting infrared detection signals; after the previous group of signal transceiving unit groups perform the above operation steps, the next group of signal transceiving unit groups perform their operation steps, and the previous group of signal transceiving unit groups are closed after the previous group of signal transceiving unit groups perform the operation steps.
After all the signal transceiving unit groups perform the above operation steps once, it may be referred to as completing a detection cycle. The duration of one detection period can be set according to needs, for example, one detection period can last tens or hundreds of milliseconds; the present invention is not limited to any particular duration. Since the time for one detection period is usually very short and the time for the user to operate the container is relatively long, the detection can be continuously polled during the time for the user to operate the container, i.e. when one detection period is completed, the return is repeated until the container is used. Thus, the dropped goods can be detected more accurately and precisely. It will also be appreciated that the time for one detection cycle is very short compared to the time for the cargo to fall, so that it does not happen that exactly all infrared detection signals are off at the time of the cargo fall.
For example, if the container includes 8 sets of signal transceiver units, and each set of signal transceiver units includes 1 signal transmitting unit and 1 signal receiving unit, the step of sending out the synchronous electrical signal, the step of turning on the infrared receiving end, and the step of transmitting the infrared detection signal are first performed on the 1 st set of signal transceiver units. After the group 1 transceiver unit finishes executing, it will be temporarily turned off, and at this time, the group 2 transceiver unit executes the above operations, and so on until the group 8 transceiver unit finishes executing the above operations, and at this time, a detection cycle is completed. If the detection is required to be continuously carried out, the group 1 signal transceiving unit group is returned again to carry out the polling operation repeatedly. It should be understood, of course, that the method of the present invention has been explained and illustrated above only by way of exemplary embodiments, and the present invention is not limited to any particular way, and the number of signal transceiver groups, the duration of the detection period and the time may be set as required.
With continued reference to FIG. 1, in one embodiment, the container drop detection method may further comprise the steps of:
determining the number of signal receiving units receiving the infrared detection signals within a first set time;
determining that the cargo falls in response to the number of the signal receiving units receiving the infrared detection signals being smaller than the actual total number of the signal receiving units;
and determining that no cargo falls in response to the number of signal receiving units receiving the infrared detection signal being equal to the actual total number of signal receiving units.
In other words, according to the above description, in this embodiment, when the number of signal receiving units that receive the infrared detection signal is smaller than the actual total number of signal receiving units, it is indicated that there is a case where the infrared detection signal is not received by the signal receiving unit, that is, there is a case where the infrared detection signal is cut by falling goods, and it can be determined that there is a falling goods; when the number of the signal receiving units receiving the infrared detection signals is equal to the actual total number of the signal receiving units, it is indicated that all the signal receiving units receive the infrared detection signals, that is, the infrared detection signals are not cut by falling goods, and at this time, it can be determined that no goods fall. It should be understood that, since the step of detecting the falling goods by infrared light employs the aforementioned means for providing the signal transmitting unit and the signal receiving unit to pair synchronously with each other, the step of detecting can have higher detection accuracy and detection precision.
Further, it should be understood that the first set time described above may be any suitable length of time set as desired. For example, in one embodiment, the first set time may be any period of time during which the user uses the container (e.g., a period of time from when the user starts to spring out the item after the user selects the item); as another example, in one embodiment, the first set time may be the total time that the user triggers the start of use of the container. That is, the selection of the first set time is not limited to a certain type or types and a certain duration length, which may be set according to circumstances, and the present invention is not limited thereto.
Further, in one embodiment, the container drop detection method may further comprise the steps of:
determining whether the signal receiving unit does not receive the infrared detection signal all the time within a second set time;
and in response to the signal receiving unit not receiving the infrared detection signal all the time, determining that the group of the signal transmitting unit and the signal receiving unit are in fault.
According to the description of the above embodiments, the above embodiments provide a self-test mechanism for the infrared transmitting end and the infrared receiving end of the signal transmitting unit and the signal receiving unit. Specifically, if during the use of the container by the user, the infrared detection signal is not received by one or some of the signal receiving units, two situations may actually occur: the first is that the infrared detection signal is cut by falling goods, so that the infrared receiving end does not receive the signal; another possibility is that the infrared transmitting end and/or the infrared receiving end fails, resulting in no infrared detection signal.
Therefore, according to the above embodiment, if it occurs that none or some of the signal receiving units receive the infrared detection signal all the time within the second set time, it can be considered that the group of the signal transmitting unit and the signal receiving unit are malfunctioning. This is because if the first situation occurs, the infrared receiving end cannot always receive a signal. Therefore, through the arrangement mode, not only can the falling goods be accurately and precisely detected, but also the self-checking of the container equipment can be simultaneously carried out, so that the use and maintenance operation is improved and optimized.
In one embodiment, similar to the above with respect to the first setting time, the second setting time may also be set according to specific needs, and the invention is not limited to a certain or some specific time.
Further, in an embodiment of the present invention, the container falling detection method may further include the steps of:
and responding to the opening of the infrared receiving end and the passing of a third set time, and transmitting an infrared detection signal to the infrared receiving end by the signal transmitting unit.
Specifically, in one embodiment, after the signal transmitting unit transmits the synchronous electrical signal to the signal receiving unit, when the infrared receiving terminal is turned on, the infrared detection signal can be immediately transmitted to the infrared receiving terminal, so that the operation is faster; in the above embodiment, the signal transmitting unit may transmit the infrared detection signal to the infrared receiving terminal after the infrared receiving terminal is turned on and the third set time elapses, so that the start preparation time may be reserved for the infrared transmitting terminal, and the start preparation of the infrared receiving terminal may be made more sufficient.
In one embodiment, similar to the above regarding the first setting time and the second setting time, the third setting time can also be set according to specific needs, and the invention is not limited to a certain time or a certain specific time.
With continued reference to FIG. 1, in one embodiment, the container drop detection method may further comprise the steps of:
the signal receiving unit sends a self-checking electric signal to the signal transmitting unit;
in response to receiving the self-detection electric signal, the signal transmitting unit sends a synchronous electric signal to the signal receiving unit matched with the signal transmitting unit;
and in the fourth set time, sending an abnormal warning in response to the fact that the signal transmitting unit does not receive the self-detection electric signal.
According to the description of the above embodiments, the above embodiments provide a hardware circuit self-test mechanism between the signal transmitting circuit and the signal receiving circuit of the signal transmitting unit and the signal receiving unit. That is, before the matching/synchronizing operation described above is performed, a self-detection electrical signal is first sent out by the signal receiving unit to the signal transmitting unit to detect whether or not the hardware circuits between the signal transmitting unit and the signal receiving unit are both able to operate normally.
In one embodiment, if the self-checking electrical signal is received, the signal transmitting unit sends out a synchronous electrical signal to the signal receiving unit matched with the signal transmitting unit; in another embodiment, if the signal transmitting unit does not receive the self-test signal within the fourth set time, an abnormal alarm is sent out, and a hardware circuit between the signal transmitting unit and the signal receiving unit is determined to be possibly faulty. Therefore, the container dropping method provided by the invention is additionally provided with a hardware circuit self-checking mechanism before the use of a user, so that the normal operation and running of the subsequent steps are ensured.
In one embodiment, similar to the above description about the first set time to the third set time, the fourth set time may also be set according to specific needs, and the invention is not limited to a certain time or a certain specific time.
In addition, in an embodiment, the hardware circuit self-checking mechanism may be executed when the container is powered on for the first time, that is, when the container is powered on for the first time under the condition of power failure; for another example, the hardware circuit self-checking mechanism described above may also be implemented each time the user uses the container. That is, the starting timing of the hardware circuit self-checking mechanism is not limited to any particular one, and may be set as appropriate as needed.
It should be noted that, in one embodiment, the sending of the self-test signal in the present invention may include sending an electrical pulse signal or a wireless signal; and the sending of the synchronization electric signal in the present invention may include sending an electric pulse signal or a wireless signal. For example, the self-test electrical signal and the synchronization electrical signal emitted may be electrical frequency pulse signals; again for example a radio signal. However, it should be understood that the above signals do not limit the present invention in any way, and an appropriate electrical signal may be selected and used as needed.
