Based on this, in one or more embodiments of the present description, the control instructions include movement instructions, the control module further configured to:

Here, the movement instruction includes, but is not limited to, forward, backward, left, right, rotation, and the like.

Through such technical scheme, the doctor can direct control telemedicine robot's removal makes it be close to, keep away from or aim at the patient with characteristic angle, realizes doctor to patient's multi-angle, nimble observation.

When a doctor examines a patient, the doctor can contact the body of the patient through hands besides using a detection instrument, and observe whether the corresponding body part of the patient has physiological reactions such as pain under actions such as pressing and pressing.

In one or more embodiments of the present description, a robotic manipulation pressure sensor may be utilized to detect a patient. As previously mentioned, the detection device comprises a pressure sensor. In particular, the robot presses the pressure sensor against the patient's body, which generates a reaction force on the pressure sensor, which can be picked up by the pressure sensor. The doctor feels the reaction force of the patient's body to the hands differently due to the difference in the experience and hand strength of each doctor.

To enable the physician to accurately determine the condition of the patient's body, the control module is further configured to:

acquiring pressure information provided by a pressure sensor and multimedia information provided by the interaction module in a corresponding time period; here, the pressure information is a reaction force of the patient's body against the pressure sensor.

Here, the pressure level library includes a correspondence relationship between pressure information and a level of pressure (reaction force of the patient's body) felt by the doctor.

It should be understood that the pressure level library can be established through multiple tests when the personal account of the doctor is established, so that the corresponding relation between the pressure level felt by the doctor and the pressure information is defined. Alternatively, based on experimentation, the pressure ranges typically experienced by a physician are determined and sub-ranges are drawn, each sub-range corresponding to a pressure level. And determining the pressure grade according to the sub-range of the pressure information. Obviously, the pressure level experienced by the physician may be quite different for the same pressure information.

Therefore, the pressure information is converted into the pressure level which corresponds to the experience of the doctor and is convenient to judge, and the doctor can accurately judge the physical condition of the patient according to the experience.

And transmitting the pressure level and the multimedia information to the remote control equipment.

Here, the doctor using the remote control device can acquire not only the pressure level information but also multimedia information of the patient at the pressure level, including but not limited to expression, sound, etc., so that the doctor can determine the next operation according to the reaction of the patient, for example, the manipulator continues to press the pressure sensor toward the patient.

Therefore, according to the technical scheme, the doctor can perform palpation detection on the patient by using the pressure sensor, so that the physical condition of the patient can be more comprehensively known.

In addition to palpation detection, doctors also often determine the physical condition of a patient by observing the facial complexion, mental state, etc. of the patient. In the remote medical treatment process, the image information provided by the interaction module is influenced by ambient light, has the possibility of distortion, and cannot truly reflect the facial complexion of the patient.

To solve this technical problem, in one or more embodiments of the present description, the detection device comprises a skin tone plate. By utilizing the skin color plate, the adjustment of image information is realized, so that a doctor can accurately obtain the face color information of a patient, and misjudgment caused by image distortion is avoided.

Specifically, before the interaction module is used to implement multimedia information interaction with a remote control device, the control unit is further configured to:

a first image including a patient's face and the skin tone plate is acquired.

Here, the flesh tone plate includes a plurality of flesh tone pixel points.

Alternatively, the skin tone plate may be placed by a robotic arm in close proximity to the patient's face.

Further, as an alternative, the flesh tone plate is provided on the robot arm. When the skin color plate is used, the manipulator is only required to be placed on the face accessory of the patient.

And extracting pixel information corresponding to the skin color plate in the first image.

And determining the color temperature corresponding to the first image according to the pixel information.

It should be understood that, under different color temperatures, the pixel information of the skin color is located in different areas, and the color temperature of the surrounding environment can be determined according to the area where the pixel information is located. There are various ways to determine the color temperature based on the pixel information, not just to mention one.

Here, the adjusted image can reflect the real face of the patient, helping the doctor to judge the physical condition of the patient.

To facilitate free movement of the telemedicine robot, independent of the power supply, the telemedicine robot in one or more embodiments of the present description further comprises a power module. The power module is configured to supply power to the control module, the manipulator 2, the conditioning platform 1 and the interaction module 3.

Optionally, the power module includes at least one charging socket, a battery, and a power management unit. The power management unit comprises a charging management subunit, an electric quantity detection subunit, a power conversion subunit and a distribution subunit.

step 101: and acquiring the residual capacity of the battery.

Here, with the electric power detecting subunit, the remaining electric power of the battery can be acquired.

Step 102: and comparing the residual electric quantity with a preset safety electric quantity.

It should be noted that the preset safe electric quantity can be set according to the use environment of the telemedicine robot. For example, if the range of motion of the telemedicine robot is small, the preset safe electric quantity may be set to be low, for example, 10%; the range of motion of telemedicine robot is big, then it can be higher that preset safe electric quantity sets up, for example 20% to ensure telemedicine robot to keep enough electric quantity to move to the position of charging seat.

Step 103: and if the residual electric quantity is less than the preset safe electric quantity, acquiring a charging path.

It should be understood that if the remaining power is greater than or equal to the preset safe power, a charging path does not need to be acquired.

For the charging path, it may be determined by the remote control device.

For example, if the remaining power is less than the preset safe power, the control module sends a charging request to a remote control device. And the remote control equipment searches the target charging seat by using a local map (where the telemedicine robot is located) and formulates a charging path.

Step 104: and moving to the target charging seat based on the charging path.

Step 105: determining the target charging seat and positioning for charging by using the induction signal; wherein the induction signal is sent out by the target charging seat.

In this step, in the process of approaching the target charging seat, the remote medical robot can conveniently determine the target charging seat and perform positioning charging by using the induction signal. Here, the sensing signal may be an infrared signal.

One or more embodiments of the present disclosure further provide another method for acquiring a charging path, referring to fig. 5, where the step of acquiring the charging path specifically includes:

step 201: and acquiring the current position, and searching the target charging seat according to a preset rule based on the current position.

It should be noted that, since the number of the charging seats may be plural, the target charging seat needs to be searched. Here, the preset rule may be the shortest distance or the shortest time, or may be another rule, for example, the shortest obstacle, which is not limited herein.

Step 202: and determining the charging path according to the current position and the position of the target charging seat.

According to the technical scheme, the remote medical robot can independently complete charging without the participation of remote control equipment, and is more intelligent and efficient.

It should be appreciated that in this manner of obtaining a charging path, a charging notification may be sent to the remote control device. In this way, a doctor using the remote control apparatus can know the state of the telemedicine robot in time.

and searching induction signals, and determining the target charging seat based on the induction signals.

Here, although the remote medical robot knows the general position of the target charging stand while approaching the target charging stand, other objects may exist around the remote medical robot, and thus it is necessary to determine the target charging stand using an induction signal.

It should be appreciated that the target charging dock and the telemedicine robot are aligned to enable charging. Here, the alignment may be charging contact alignment, or the telemedicine robot may be in a range in which charging can be achieved (suitable for contactless charging). When the induction signal is detected at a preset angle, the remote medical robot is indicated to be aligned with the target charging seat, so that the remote medical robot can be charged after positioning is completed.

In one or more embodiments of the present invention, the charging method further includes:

monitoring the electric quantity of the battery in the charging process;

Step 303: acquiring a control instruction sent by a remote controller, wherein the control instruction comprises target position information;

in this step, the object may be a patient, an object charging dock, a detection device, or the like. Here, the doctor usually knows the location of the patient, such as the patient's room number and bed. The doctor can determine the target charging dock based on the local map. Using the multimedia information, the location of the detection device can be determined.

Step 304: determining a movement path of the telemedicine robot to the target location based on the target location information, the local map, and telemedicine robot positioning information; wherein the telemedicine robot positioning information is determined based on the local map and current environmental information;

it is understood that when the target is a charging dock, the moving path is a charging path.

Step 305: and controlling the telemedicine robot to move to the target position according to the moving path.

Therefore, by the control method of the embodiment, the remote medical robot can construct a local map in any environment by using the information provided by the laser navigation radar, the camera and the photoelectric encoder, and the process does not need to be operated by a doctor. Furthermore, only the remote control equipment is needed to provide the position information of the target, the remote medical robot can automatically move, the flexibility is high, and various requirements of remote medical treatment are met.

In one or more embodiments of the present invention, controlling the telemedicine robot to move to the target position according to the movement path includes:

and determining the moving distance of the remote medical robot according to the positioning information corresponding to the starting and stopping moments of the preset time period.

For a preset time period, the total time required for the telemedicine robot to complete the movement path may be divided into 3 parts and 4 parts, for example. The total length of time is determined based on the average moving speed of the telemedicine robot. Starting timing when the telemedicine robot starts to move, and calculating a moving distance according to a position when the telemedicine robot starts to move (a time when the time period starts) and a position after 2min (a time when the time period ends) when a preset time period is reached, for example, 2 min; and the like, and determining the moving distance every 2 min.

It should be understood that the preset distance is calculated according to the average moving speed of the telemedicine robot and a preset time period.

By the mode, the state of the remote medical robot is effectively judged by utilizing the preset time period and the preset distance, when the remote medical robot encounters an obstacle which cannot be crossed, the moving path can be determined again, and the problem that the remote medical robot cannot reach the target position due to the obstacle is solved. Here, the obstacle may be a temporary tool occupying passage, a passage door lock, or the like.

Further, in one or more embodiments of the present description, a method of handling traversable barriers is also included. Specifically, the step of controlling the telemedicine robot to move to the target position according to the moving path includes:

acquiring roadblock data by using an obstacle avoidance sensor;
