It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.
[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0038] In one embodiment, Figure 1 As shown, a track transmission control method is provided, which is applied to a track transmission control system. The track transmission control system includes a first track, a first entrance sensor is provided at the entrance of the first track, and a first exit sensor is provided at the exit of the first track. The method includes the following steps:
[0039] Step S102, obtaining a first entry signal of a first entry sensor.
[0040] The first entrance sensor is a position sensor at the entrance of the first track, used to detect whether there is a container at the entrance of the first track. The first entrance signal is used to indicate whether the container enters the first track. The first exit sensor is a position sensor at the exit of the first track, used to detect whether there is a container at the exit of the first track.
[0041] Optionally, a first inlet signal of a first inlet sensor is acquired in real time.
[0042] Optionally, when the container is placed into the entrance of the first track by a mechanical gripper or manually, or when the container is transported to the entrance of the first track via a transport device docked at the front end of the first track, a first entrance signal of the first entrance sensor is acquired.
[0043] Step S104, when the first entry signal changes, the first track is controlled to run.
[0044] The change in the first input signal refers to the change in the signal relative to the sensor photoelectric signal when it is not blocked by the container.
[0045] Optionally, when the first entrance signal changes, it indicates that the container enters the first track and is at the entrance of the first track, and the first track is controlled to run to transfer the container on the first track. The container is used to load a blood bag, and the blood bag stores blood products. Exemplarily, the container can be a blood frame or a tray for loading blood bags.
[0046] Step S106, obtaining a first outlet signal of a first outlet sensor.
[0047] Optionally, a first outlet signal of a first outlet sensor is acquired in real time.
[0048] Optionally, track transmission control is performed according to the structure and business scenarios. For example, during straight-line transmission, the first entrance signal of the first entrance sensor of the first track changes, indicating that the current container is transmitted to the exit of the first track. The first track can be directly controlled to continue running to transport the container on the first track backward. For example, when the track line needs to make a right-angle turn, it may be transferred through a lifting or rotating module, and then the first track can be controlled to continue running to transport the container on the first track backward.
[0049] Step S108, when the first exit signal changes, the first track is controlled to continue running to transport the container on the first track.
[0050] Optionally, when the first exit signal changes, indicating that the container is at the exit of the first track, the first track is controlled to continue running to output the container on the first track to the next track.
[0051] Optionally, the above method also includes: when the first exit signal changes, and the number of changes of the first entrance signal is the same as the number of changes of the first exit signal, it indicates that the current container is transferred to the exit of the first track. If a stop operation instruction of the first track is received, the first track is controlled to stop operating according to the stop operation instruction of the first track to park the container at the exit of the first track, waiting for other devices in the system to transfer or perform other operations on the container or the items contained therein.
[0052] It can be understood that when the first exit signal changes, and the number of changes of the first entrance signal is the same as the number of changes of the first exit signal, it indicates that the number of containers entering the first track is the same as the number of containers passing through the exit of the first track, and the containers transported by the first track have not failed or been lost, then the first track is controlled to stop running when a stop operation instruction of the first track is received.
[0053] Optionally, when the first exit signal changes, and the number of changes of the first entrance signal is the same as the number of changes of the first exit signal, it indicates that the current container is transmitted to the exit of the first track. If the container needs to continue to be transmitted, the continue operation control instruction of the first track is obtained, and the first track is controlled to continue to run according to the continue operation control instruction.
[0054] Optionally, the method further includes: if the first exit signal changes, and the number of changes of the first entry signal is different from the number of changes of the first exit signal, issuing an alarm signal.
[0055] The form of the alarm signal can be set as needed, such as a sound alarm signal, a vibration alarm signal, etc., but is not limited thereto.
[0056] It is understandable that if the container is lost or fails during the transmission on the first track and cannot be further transmitted, that is, the number of changes of the first input signal is different from the number of changes of the first output signal, an alarm signal is issued.
[0057] Optionally, the method further includes: if the distance that the container needs to be transported on the track is greater than a preset distance, a middle sensor is provided at a middle position of the first track to detect the position of the container.
[0058] The preset distance can be set as needed, such as 5 meters. The middle sensor is a sensor located in the middle of the first track. One or more middle sensors can be set. When there is one middle sensor, it can be set in the middle of the first track; when there are multiple middle sensors, they can be evenly distributed on the first track at equal distances.
[0059] If the distance that the container needs to be transported on the track is greater than the preset distance, it means that the container needs to be transported over a long distance. In order to ensure that the position information of the container during the long-distance transmission is accurately obtained, an intermediate sensor is set at the middle position of the first track to detect the position of the container.
[0060] Optionally, an intermediate sensor is further provided at the middle position of the first track; the method further comprises: acquiring a signal of the intermediate sensor; and determining the position of the container on the first track when the signal of the intermediate sensor changes.
[0061] Optionally, the signal of the intermediate sensor is acquired in real time.
[0062] When the signal of the middle sensor changes, it indicates that the container is transferred to the middle position of the first track.
[0063] The above-mentioned track transmission control method, the track transmission control system includes a first track, a first entrance sensor is provided at the entrance of the first track, and a first exit sensor is provided at the exit of the first track, a first entrance signal of the first entrance sensor is obtained, when the first entrance signal changes, the first track is controlled to run, and the first exit signal of the first exit sensor is obtained. When the first exit signal changes, the first track is controlled to continue running, and the first track can be accurately controlled to run to accurately transport the container on the first track.
[0064] In one embodiment, the track transport control system also includes a second track, a second entrance sensor is provided at the entrance of the second track, and the second track is the next track connected in series with the first track; when the first exit signal changes, the first track is controlled to continue to run to transport the container, and further includes: obtaining a second entrance signal of the second entrance sensor; when the second entrance signal changes, it is determined that the container enters the second track from the first track, and the second track is controlled to run to transport the container.
[0065] The track transmission control system includes at least two tracks, and the at least two tracks include a first track and a second track. Exemplarily, the track transmission control system includes five tracks, or ten tracks, etc.
[0066] The second entrance sensor is a position sensor at the entrance of the second track, and is used to detect whether there is a container at the entrance of the second track. The second entrance signal is used to indicate whether the container has reached the entrance of the second track.
[0067] Optionally, when a change in the second entrance signal is detected, indicating that the container enters the second track from the first track, the second track is controlled to operate to continue transporting the container.
[0068] Optionally, the method further includes: taking the second track as a new first track, and taking the next track connected in series with the second track as a new second track, and returning to execute the step of acquiring the first entrance signal of the first entrance sensor.
[0069] It can be understood that the track transport control system uses the second track as the new first track, and the next track adjacent to the second track in series as the new second track, and re-executes the acquisition of the first entrance signal of the first entrance sensor to continue to control the operation of the new first track, thereby realizing the transport of containers by at least two tracks.
[0070] Exemplarily, the track transmission control system includes at least a first track and a second track, the second track is the next track connected in series with the first track, a first entrance sensor is provided at the entrance of the first track, a first exit sensor is provided at the exit of the first track, a second entrance sensor is provided at the entrance of the second track, and a second exit sensor is provided at the exit of the second track; when the track transmission control system needs to transmit a container through the first track and the second track, a first entrance signal of the first entrance sensor is obtained, and when the first entrance signal changes, it indicates that the container enters the first track, and the first track is controlled to operate; a first exit signal of the first exit sensor is obtained, and when the first exit signal changes, the first track is controlled to continue to operate to transfer the container on the first track to the second track, at this time, the second track is used as the new first track, the second entrance sensor is used as the first entrance sensor of the new first track, the second exit sensor is used as the first exit sensor of the new first track, and the next track connected in series with the second track is used as the new second track, and the container is continued to be transmitted on the new first track to transfer the container to the new second track, and the cycle is repeated until the container transmission is completed, and the container can be accurately transmitted on at least two tracks.
[0071] In one embodiment, the method further comprises: when a signal of an entrance sensor on a target track in a track transport control system is obtained to change, it is determined that the container is on the target track, and then the target track is controlled to stop running.
[0072] The target track is the track to which the container is expected to be delivered.
[0073] Optionally, when the signal of the entrance sensor on the target track in the track transport control system changes, it means that the container has reached the entrance of the target track, that is, the container is on the target track, then the target track is controlled to stop running, so that the container can be accurately transported to the target track.
[0074] In one embodiment, Figure 2 The schematic diagram of track transmission state 1 is shown. The track transmission control system receives a change in the first entrance signal of the first entrance sensor of the first track, and controls the first track to start running until it enters the state as shown in FIG. Figure 3 The track transmission state 2 shown; in state 2, the first exit signal of the first exit sensor of the first track changes, when it is not necessary to continue to transmit backward, the first track is controlled to stop running, and when it is necessary to continue to transmit, the first track is controlled to continue running; Figure 4The schematic diagram shown is a track transmission state 3. When the track transmission control system receives a change in the second entrance signal of the second entrance sensor of the second track, it determines that the container enters the second track from the first track, and controls the second track to move until the second track enters state 2, that is, the second track operates as a new first track to transmit the container to the next second track in series.
