In the concrete realization of the present invention, multiple first wireless devices can be installed in the hospital, and each device in the hospital is equipped with a second wireless device. Through the connection between the first wireless device and the second wireless device, the server or the user terminal has computing The device is capable of calculating the location information of the equipment in the hospital, and obtaining the equipment type and/or equipment identification of the equipment in the hospital, so that the positioning of the equipment in the hospital can be realized. It should be noted that the equipment identification refers to the ID of the equipment in the hospital, for example, it can be a number, etc. There is a one-to-one correspondence between the equipment and the equipment identification in the hospital; the equipment type refers to the type of equipment in the hospital, for example, the equipment type is a transport monitor , Portable defibrillators, infrared ear thermometers and portable color ultrasound equipment, etc., so usually equipment types correspond to multiple hospital equipment.

Give a few examples of interviews under the specific methods of hospital positioning.

For example, the present invention can realize the positioning of equipment in the hospital through WIFI indoor positioning technology. In some embodiments, the first wireless device and the second wireless device are connected via WIFI. When positioning the equipment in the hospital, based on the wireless signal strength of the second wireless device of the equipment in the hospital and the wireless signal strength of the three first wireless devices, the difference algorithm is used to triangulate the equipment in the hospital relatively accurately. Alternatively, the signal strength of a huge number of locations can be recorded in advance, and the current location information of the device in the hospital can be determined by comparing the signal strength of the second wireless device of the current in-hospital device with the previously recorded huge amount of data.

For example, the present invention can also realize the positioning of the equipment in the hospital through the ultra-wideband UWB indoor positioning technology. In some embodiments, the first wireless device and the second wireless device are communication units that can receive and transmit extremely narrow pulses with nanoseconds or less to transmit data. When locating in-hospital equipment, use pre-arranged anchor nodes and bridge nodes with known locations to communicate with the current in-hospital equipment, and use triangulation technology to determine the position information of the in-hospital equipment, or you can record the giant in advance. The signal strength of each location point of the quantity, the current location information of the device in the hospital is determined by comparing the signal strength of the second wireless device of the current hospital device with the huge amount of data recorded in advance.

For example, the present invention can also realize the positioning of the equipment in the hospital through the Bluetooth indoor positioning technology. In some embodiments, the first wireless device and the second wireless device are connected via Bluetooth. The Bluetooth indoor positioning technology is similar to the WIFI indoor positioning technology, except that the Bluetooth indoor positioning technology uses the signal strength of Bluetooth, and the WIFI indoor positioning technology uses the signal strength of WIFI. The Bluetooth indoor positioning technology will not be repeated here.

For example, the present invention can also realize the positioning of the equipment in the hospital through the RFID fixed positioning technology. For example, in some embodiments, the first wireless device is an RFID reader, and the second wireless device is an RFID tag. The RFID reader can read the characteristic information of the RFID tag, such as the received signal strength and the equipment of the hospital equipment with the RFID tag. Type and/or equipment identification, etc.; and then determine the location of the RFID tag or the hospital equipment with the RFID tag by using the nearest neighbor method, multilateral positioning method, received signal strength and other methods.

For example, the present invention can also use infrared indoor positioning technology to realize the positioning of equipment in the hospital. For example, the first wireless device is an optical sensor for receiving and sensing infrared rays, and the second wireless device is used to transmit infrared rays; the equipment in the hospital transmits modulation through the second wireless device. The first wireless device installed in the hospital receives the infrared rays and converts them into electrical signals. Based on the electrical signals, the location of the equipment in the hospital can be calculated.

In the specific embodiment, the existing technology or the indoor positioning technology coming out in the future can be selected according to the needs to realize the acquisition of the location information of the in-hospital equipment of the present invention and the positioning of the in-hospital equipment of the present invention.

In actual situations, users sometimes only need to search for one medical device, and sometimes they need to search for multiple medical devices at the same time. The present invention can be applied to both the user searching for one medical device and the user searching for multiple medical devices. Therefore, in some embodiments, the in-hospital device search request in step 100 can be used to search for one in-hospital device required by the user. In other embodiments, the in-hospital device search request in step 100 can be used to find multiple in-hospital devices required by the user. , The following is explained by situation.

In some embodiments, the in-hospital device search request in step 100 is used to find an in-hospital device required by the user, and in some embodiments, the in-hospital device search request includes one or both of device type information and device identification.

In some implementations, the user terminal may have an input box as shown in Figure 2(a) for the user to input device identification, where each device identification corresponds to a specific device, so that the user enters the device identification and then clicks to find , The input of the device search request in the hospital is completed; the figure shows an example of the input device identification as N22-001. Please refer to FIG. 3, which is a system diagram of a hardware implementation of the path planning method, which can be called a path planning system. The server, etc. can periodically obtain the equipment information and location information of the equipment in the hospital, where the equipment information includes equipment type and/or equipment identification, etc.; in this way, when the server receives the equipment search request through the user terminal, it is based on the equipment contained in the equipment search request in the hospital Identification, find the location information of the corresponding in-hospital equipment—for example, when the server receives the in-hospital equipment search request as shown in Figure 2(a), the server finds the location information with the equipment identification N22-001. After finding the location information of the equipment in the corresponding hospital, and since the location information of the user terminal can be obtained, based on the location information of the user terminal and the location information of the equipment in the hospital, it is planned to arrive at the location from the user terminal on the preset map of the hospital. State the path of the equipment location in the hospital, for example, plan the path from the user terminal location to the equipment in the hospital required by the user on a preset map of the hospital, so that the path is the shortest path or the least time-consuming path—for example, still use Figure 2 (a) As an example, plan a shortest path or the least time-consuming path from the user terminal to the device with the identification N22-001. It should be noted that Figure 3 shows that the path planning of step 400 is completed on the server, and then the server sends the path planning results to the user side for display, but it is understandable that step 400 can also be completed on the user side In this case, the server sends the acquired location information of the hospital equipment to the user terminal based on the device search request, and the user terminal completes the path planning based on the hospital equipment and its own location information.

In some embodiments, the user terminal may have a selection box as shown in FIG. 2(b) for the user to select the device type; the figure shows that the user has selected the portable defibrillator as the device type. Similarly, the server, etc. can periodically obtain the equipment information and location information of the hospital equipment; in this way, when the server receives the hospital equipment search request through the user terminal, it finds the hospital equipment of the equipment type based on the equipment type included in the hospital equipment search request Location information-For example, when the server receives the hospital device search request as shown in Figure 2(b), the server searches for the location information of the portable defibrillator. After finding the location information of the equipment in the corresponding hospital, and since the location information of the user terminal can be obtained, based on the location information of the user terminal and the location information of the equipment in the hospital, it is planned to arrive at the location from the user terminal on the preset map of the hospital. To describe the path of the device location in the hospital, for example, plan a path from the location of the user terminal to the device in the hospital required by the user on a preset map of the hospital, so that the path is the shortest path or the path that consumes the least time. It should be noted that since the device type can correspond to multiple in-hospital devices at the same time, the server may find the location information of multiple in-hospital devices of the same device type at the same time, so based on the location information of the user terminal and the location of the in-hospital device When the information is used for path planning, it can be to select the device in the hospital closest to the user terminal for routing rules, for example, select the device in the hospital closest to the user terminal and plan the path from the location of the user terminal to the device in the user hospital on the preset hospital map , So that the path is the shortest path or the least time-consuming path; it can also be planned on the preset hospital map from the location of the user terminal to each in-hospital equipment that meets the equipment type, and then select the shortest or time-consuming path The least path is used as the final planned path.

In some embodiments, the in-hospital device search request in step 100 may be used to find multiple in-hospital devices required by the user, and in some embodiments, the in-hospital device search request includes one or both of the information of the device type and the device identification.

In some implementations, the user terminal may have an interface as shown in Figure 4. The hospital devices of the same device type are displayed together, and there are check boxes in front of the device identification of the hospital devices. When the check box is checked, it means that To find the device, the user selects the corresponding in-hospital device by checking one or more check boxes in front of the device identification, and then clicks Find to complete the input of the in-hospital device search request; the figure shows that the user has checked the device The transport monitor marked N22-002 and the portable defibrillator marked BD-001. Similarly, the server, etc., can periodically obtain the equipment information and location information of the equipment in the hospital, where the equipment information includes equipment type and/or equipment identification, etc.; in this way, when the server receives the equipment search request in the hospital through the user terminal, it is based on the equipment search request in the hospital. The included equipment identification, find the location information of the corresponding in-hospital equipment-for example, when the server receives the in-hospital equipment search request as shown in Figure 4, the server will search for the transfer monitor with the equipment identification N22-002 and the equipment identification as BD -001 portable defibrillator location information. After finding the location information of the equipment in the corresponding hospital, and since the location information of the user terminal can be obtained, based on the location information of the user terminal and the location information of the equipment in the hospital, it is planned to arrive at the location from the user terminal on the preset map of the hospital. The path of the device location in the hospital, for example, is planned on a preset map of the hospital, from the location of the user terminal to the multiple in-house devices required by the user in sequence, so that the path is the shortest path or the path that consumes the least time.

In some embodiments, the user can also select the type of device to be searched by selecting the check box in front of the device type in FIG. 4, and then click Search to complete the input of the hospital device search request. Similarly, the server, etc. can periodically obtain the equipment information and location information of the hospital equipment; in this way, when the server receives the hospital equipment search request through the user terminal, it finds the hospital equipment of the equipment type based on the equipment type included in the hospital equipment search request Location information. After finding the location information of the equipment in the corresponding hospital, and since the location information of the user terminal can be obtained, based on the location information of the user terminal and the location information of the equipment in the hospital, it is planned to arrive at the location from the user terminal on the preset map of the hospital. The path of the device location in the hospital, for example, is planned on a preset map of the hospital, from the location of the user terminal to the multiple in-house devices required by the user in sequence, so that the path is the shortest path or the path that consumes the least time. It should be noted that since the device type can correspond to multiple in-hospital devices at the same time, when the user selects multiple device types for searching, the server will find the location information of multiple in-hospital devices of the same device type for each device type. Therefore, when the path planning is performed based on the location information of the user terminal and the location information of the equipment in the hospital, the path planning result obtained is a path from the user terminal, and the path will pass through each device type required by the user. A device.

In some embodiments, the present invention also obtains the location information of the user terminal in real time; when it is determined that the user terminal has reached one of the in-hospital equipment required by the user, the position information of the remaining in-hospital equipment required by the user is re-acquired and re-planned The path from the current location of the user terminal to the in-hospital equipment required by the remaining users, so that the path is the shortest path or the path that consumes the least time.

Those skilled in the art can understand that FIGS. 2 and 4 are only some examples of the user terminal receiving the user input device search request, and are not used to limit the user terminal to only receive the user input device search request in these ways.

In one embodiment, in the present invention, planning the path from the user terminal location to the location of the equipment in the hospital on a preset map of the hospital may include: according to the elevator, stairs and/or current path included in the path on the preset map of the hospital Time to plan a path, so that the path is the shortest path or the least time-consuming path.
