Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pneumatic logistics, and in particular to a pneumatic logistics transmission system with fault point detection and a detection method. Background Art
[0002] With the development of social science and technology, pneumatic tube logistics transmission systems are used in the transmission of medicines and documents in hospitals, which fully improves the efficiency of the circulation of goods in hospitals. During the high-frequency transmission and use of pneumatic tube logistics transmission systems, due to the frequent friction of the transmission bottles on the pipelines, the pipeline joints, brackets and other parts are easy to loosen and fall off. In addition, the pipelines of pneumatic tube logistics are generally hidden in the ceiling or concealed by blocks, etc., making it difficult to observe the use of the pipelines and troublesome to maintain. Once a fault occurs, it is difficult for maintenance personnel to troubleshoot due to the influence of its installation position, which affects the operation of the entire logistics system. Therefore, it is necessary to study a suitable detection method for pneumatic tube logistics transmission systems to address the above problems. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide a pneumatic logistics transmission system and a detection method with fault point detection, which simplifies the fault detection procedure during the transmission process of the pneumatic logistics system, reduces manpower and costs, and realizes accurate finding of the fault point under the premise of engineering concealment.
[0004] The technical solution adopted by the present invention to solve the technical problem is: to provide a pneumatic tube logistics transmission system with fault point detection and a detection method, the pneumatic tube logistics transmission system is used for processing the pipelines and transport bottles of the hospital pneumatic tube logistics system to improve the efficiency of the hospital pneumatic tube logistics in performing tasks, and the detection method includes the following steps:
[0005] Step 1: Pre-embed pressure detection devices and site sensors during pipeline construction;
[0006] Step 2: Obtain the site sensor information during the use of the pneumatic tube system to determine whether there is a fault;
[0007] Step 3: During the use of the pneumatic tube system, pipeline information sent by multiple pressure detection devices installed on the pipeline is obtained to determine whether there is a fault;
[0008] Step 4: The terminal data board processes the data and outputs the location of the fault point;
[0009] Step 5: The fault point location information is uploaded to the cloud, and the information is sent to the APP and received by the maintenance personnel.
[0010] As a supplement to the technical solution described in the present invention, in the step 2, the site sensor information is obtained specifically when the transport bottle passes through the site, the sensor collects information and sends the information back to the terminal data board, and the terminal will display that the transport bottle has passed.
[0011] As a supplement to the technical solution described in the present invention, the process of obtaining sensor information in step 2 to determine whether there is a fault is as follows:
[0012] S1. Determine whether the waiting time of the hospital gas tube transport bottle being stuck due to a failure is greater than a preset threshold;
[0013] S2. If the waiting time is greater than a preset threshold, the self-rescue system is activated to centrally increase the fan air volume; otherwise, the transportation system operates normally;
[0014] S3. If the transport bottle continues to move forward after the self-rescue system is turned on, indicating successful escape, a fault record is output;
[0015] S4. If the transport bottle does not continue to move forward after the self-rescue system is turned on, the fault will be reported to the terminal data board and a fault report will be output.
[0016] As a supplement to the technical solution described in the present invention, the calculation formula of the preset threshold in S1 is: T=L / V; wherein T is the preset time threshold required, L is the length of the pipeline between the stations, and V is the speed of the transport bottle; since the positions between the stations are fixed, the value of the pipeline length L is fixed, the speed of the transport bottle of the pneumatic logistics transmission system is basically fixed under normal transportation conditions, so the preset time threshold is fixed.
[0017] As a supplement to the technical solution described in the present invention, in the above S3, when the demand for the pneumatic logistics transportation system is not large, the pressure detection device between the two stations is started to perform air pressure detection.
[0018] As a supplement to the technical solution of the present invention, the process of determining whether there is a fault in step 3 is as follows:
[0019] S1. Determine whether the pressure difference between the two pressure detection devices on the pipeline is normal;
[0020] S2, the first pressure detection device is located on the main pipeline surface of the pneumatic logistics system pipeline, and is the detection device closest to the fan in the pneumatic logistics pipeline to be tested; judge whether the difference between the first pressure data and the fan wind pressure is within a preset range, if so, read the second pressure data, the second pressure data is the pressure data detected by the second pressure detection device, and the second pressure detection device is the next detection device adjacent to the first pressure detection device, if not, the pipeline between the first pressure detection device and the fan is abnormal, after the pipeline between the first pressure detection device and the fan is abnormal, output the relevant data as a fault report, and upload it to the cloud;
[0021] S3. Determine whether the difference between the first pressure data and the second pressure data is within a preset range. If so, determine that the pipeline between the first pressure detection device and the second pressure detection device is normal, and continue to detect the pressure of the section between the next pressure devices. Otherwise, determine that the pipeline between the first pressure detection device and the second pressure detection device is abnormal. After the pipeline between the first pressure detection device and the second pressure detection device is abnormal, output the relevant data as a fault report and upload it to the cloud.
[0022] As a supplement to the technical solution described in the present invention, the pressure detection device in step three includes a sensor, a processor and a transceiver that are communicatively connected, wherein the sensor is used to detect the pipeline pressure, the processor is used to read the sensor parameters and perform data processing, and the transceiver is used to send and receive messages.
[0023] Beneficial effects: The present invention relates to a pneumatic tube logistics transmission system and detection method with fault point detection, which simplifies the fault detection procedure during the transmission process of the pneumatic tube logistics system, reduces manpower and costs, and realizes accurate finding of the fault point under the premise of engineering concealment. At the same time, through self-rescue methods such as transport bottles, preliminary self-checking and solving of faults can be achieved during the peak period of pneumatic tube logistics use. The overall system is easy to operate and is suitable for all newly built and renovated pneumatic tube logistics pipelines. In addition, through the location recording of the fault point and the use of statistics, the frequent fault points of the pneumatic tube logistics pipeline can be better determined, and at the same time, it plays a positive role in promoting the optimization of subsequent pneumatic tube logistics processes.

[0029] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.
[0030] The embodiments of the present invention relate to a pneumatic tube logistics transmission system with fault point detection and a detection method, such as Figure 1-5 As shown, the detection method comprises the following steps:
[0031] Step 1: Pre-embed pressure detection devices and site sensors during pipeline construction;
[0032] Step 2: Obtain the site sensor information during the use of the pneumatic tube system to determine whether there is a fault;
[0033] Step 3: During the use of the pneumatic tube system, pipeline information sent by multiple pressure detection devices installed on the pipeline is obtained to determine whether there is a fault;
[0034] Step 4: The terminal data board processes the data and outputs the location of the fault point;
[0035] Step 5: The fault point location information is uploaded to the cloud, and the information is sent to the APP and received by the maintenance personnel.
[0036] Further, attached Figure 5 This is a structural diagram of the pressure detection device described in step one, which consists of a sensor, a processor and a transceiver that are communicatively connected, wherein the sensor is used to detect pipeline pressure, the processor is used to read sensor parameters and perform data processing, and the transceiver is used to send and receive messages.
[0037] Further, attached Figure 4 This is a structural diagram of the pneumatic logistics transmission system, which shows the pre-buried pressure detection device during the pipeline construction process described in step one, that is, the pressure detection device is attached to the surface of the pneumatic logistics pipeline, and the relevant data is transmitted to the switch through the transceiver, and finally uploaded to the server cloud by the switch.
[0038] Attached Figure 2The flowchart for determining whether the transmission bottle is faulty is shown in step 2. The process of obtaining sensor information to determine whether there is a fault includes:
[0039] Determine whether the waiting time of the hospital's pneumatic tube transport bottle that has encountered a fault and remains stationary is greater than a preset threshold; the preset threshold calculation formula is: T=L / V, T is the desired preset time threshold, L is the length of the pipeline between the stations, and V is the speed of the transport bottle; since the positions between the stations are fixed, the value of the pipeline length L is fixed, and the speed of the transport bottle of the pneumatic tube transport system is basically fixed under normal transport conditions, the preset time threshold is fixed;
[0040] If the waiting time is greater than a preset threshold, the self-rescue system is activated to centrally increase the air volume of the fan; after the fan increases the air volume, the increased wind pressure gives thrust to the pipeline, so that the collided transport bottle continues to move forward;
[0041] After the self-rescue system is turned on, the transport bottle continues to move forward to indicate successful escape, and a fault record is output. Furthermore, the fault report performs maintenance and troubleshooting on the location recorded in the fault record during a period when the pneumatic tube system is not frequently used, and the subsequent pneumatic tube system is guaranteed to operate normally through maintenance and troubleshooting;
[0042] After the self-rescue system is turned on, if the transport bottle does not continue to move forward, the fault is reported to the terminal data board and a fault report is output. The fault report is transmitted to the terminal data board through a transceiver and an alarm is given to the maintenance personnel, thereby prompting the maintenance personnel to perform maintenance.
[0043] Attached Figure 3 To determine the pipeline air pressure flow chart, step three obtains pipeline information sent by multiple pressure detection devices installed on the pipeline during the use of the pneumatic logistics system, and the process of determining whether there is a fault includes:
[0044] Determine whether the pressure difference between the two pressure detection devices on the pipeline is normal;
[0045] The specific steps are as follows: the first pressure detection device is located on the main pipe surface of the pneumatic logistics system pipeline and is the detection device closest to the fan in the pneumatic logistics pipeline to be tested;
[0046] Determining whether the difference between the first pressure data and the fan wind pressure is within a preset range;
[0047] If yes, read the second pressure data, where the second pressure data is the pressure data detected by the second pressure detection device, and the second pressure detection device is the next detection device adjacent to the first pressure detection device;
[0048] Determining whether a difference between the first pressure data and the second pressure data is within a preset range;
[0049] If so, it is determined that the pipeline between the first pressure detection device and the second pressure detection device is normal, and the pressure of the section between the next pressure detection device is continuously detected; otherwise, it is determined that the pipeline between the first pressure detection device and the second pressure detection device is abnormal;
[0050] When an abnormality occurs in the pipeline between the first pressure detection device and the second pressure detection device, the relevant data is output as a fault report and uploaded to the cloud.
[0051] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0054] The above is a detailed introduction to a pneumatic logistics transmission system and detection method with fault point detection provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
