DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To make the objectives, technical solutions and advantages of the present invention more clear, the following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work fall within the scope of protection of the present invention.

[0030] According to an embodiment of the present invention, a lighting device for maintenance is provided. Refer to Figure 1 the structural schematic diagram of an embodiment of the device of the present invention as shown. The lighting device for maintenance may include: a lighting unit (such as a maintenance lamp 5), a moving unit, a sensing unit, and a driving unit.

[0031] Among them, the sensing unit is installed on the lighting unit and the moving unit, and is configured to send and receive the sensing signal, so as to sense whether there is an obstacle at or within a set range of the position where the sensing unit itself is located by sending and receiving the sensing signal, and regard the obstacle as a maintenance personnel. Among them, if the sensing signal is interrupted, it is determined that there is a maintenance personnel at or within a set range of the position where the sensing unit itself is located. If the sensing signal is not interrupted, it is determined that there is no maintenance personnel at or within a set range of the position where the sensing unit itself is located.

[0032] For example: after sending the sensing signal, judge whether the signal is interrupted according to the reception condition of the sent sensing signal. For example, after sending the sensing signal, calculate the distance of the obstacle according to the time interval of the reflected sensing signal to judge whether there is an obstacle, or determine whether there is an obstacle according to the signal strength of the reflected sensing signal.

[0033] The lighting unit is installed on the moving unit and can move on the moving unit under the drive of the driving unit, and is configured to turn on the lighting unit itself when there is a maintenance personnel at or within a set range of the position where the sensing unit itself is located, so as to achieve lighting.

[0034] The driving unit is installed between the lighting unit and the moving unit, and is configured to move the lighting unit on the moving unit to the position where the maintenance personnel is located or within a set range of the position where the maintenance personnel is located when the maintenance personnel moves, so as to achieve the movement of the lighting unit following the maintenance personnel.

[0035] Thus, by enabling the lighting unit to follow the maintenance personnel, the position of the maintenance lamp relative to the personnel can be adjusted in real time according to the actual needs of the maintenance personnel, ensuring that the maintenance lamp moves with the personnel, meeting the requirements of the illuminance index of the maintenance personnel's working environment, significantly reducing the configuration requirements for multiple maintenance lamps or high-power maintenance lamps inside large units, improving the maintenance convenience, and saving the operation cost. Therefore, it is possible to solve the problem that the maintenance lamp inside a large unit (such as a packaged air conditioner unit) is fixed in position and insufficient illuminance cannot be avoided at the position of the far lamp.

[0036] In some embodiments, the sensing unit includes a mobile sensing unit and a fixed sensing unit. The sensing signal includes a first sensing signal sent by the mobile sensing unit and a second sensing signal sent by the fixed sensing unit.

[0037] Among them, the mobile sensing unit is installed on the lighting unit or on the driving unit, and is configured to send and receive the first sensing signal, so as to sense whether there is a maintenance personnel at the position where the mobile sensing unit itself is located or within a set range of the position where the mobile sensing unit itself is located by sending and receiving the first sensing signal. If the first sensing signal is interrupted, it is determined that there is a maintenance personnel at the position where the mobile sensing unit itself is located or within a set range of the position where the mobile sensing unit itself is located. If the first sensing signal is not interrupted, it is determined that there is no maintenance personnel at the position where the mobile sensing unit itself is located or within a set range of the position where the mobile sensing unit itself is located.

[0038] The lighting unit is configured to be in an on state when there is a maintenance personnel at the position where the mobile sensing unit is located, so as to achieve lighting.

[0039] The fixed sensing unit is installed at a set node on the mobile unit, and is configured to send and receive the second sensing signal when the lighting unit is in an on state, so as to sense whether there is a maintenance personnel at the position where the fixed sensing unit itself is located or within a set range of the position where the fixed sensing unit itself is located by sending and receiving the second sensing signal. If the second sensing signal is interrupted, it is determined that there is a maintenance personnel at the position where the fixed sensing unit itself is located or within a set range of the position where the fixed sensing unit itself is located. If the second sensing signal is not interrupted, it is determined that there is no maintenance personnel at the position where the fixed sensing unit itself is located or within a set range of the position where the fixed sensing unit itself is located.

[0040] The driving unit is configured to move the lighting unit on the moving unit to the position where the fixed sensing unit is located or within a set range of the position where the fixed sensing unit is located when there is a maintenance personnel at the position where the fixed sensing unit is located or within a set range of the position where the fixed sensing unit is located, so as to realize the movement of the lighting unit following the maintenance personnel.

[0041] For example: a mobile sensing unit, such as an infrared sensing device 4 provided together with a maintenance lamp 5 and a driving device 3. A fixed sensing unit, such as a first infrared sensing device to a sixth infrared sensing device provided on a frame. The moving unit is such as a frame. The maintenance lamp 5, the driving device 3, the infrared sensing device 4 and the frame can form a self-propelled maintenance lamp arrangement structure. This self-propelled maintenance lamp arrangement structure, a self-propelled maintenance lamp and its control method capable of automatically moving relative to maintenance personnel entering the interior of the unit, can ensure the illumination requirement of the maintenance personnel's working environment and reduce the need for other maintenance lamps.

[0042] In some embodiments, it further includes: the driving unit is further configured to, after moving the lighting unit on the moving unit to the position where the maintenance personnel are located or within a set range of the position where the maintenance personnel are located, if the sensing unit senses that there is no maintenance personnel at the position where it is located or within a set range of the position where it is located within a set time period, move the lighting unit on the moving unit to a set position or an initial position of the maintenance door of the equipment to be maintained, so as to realize the reset of the lighting unit. That is, if the maintenance personnel leave the maintenance door of the equipment to be maintained, that is, when there is no maintenance personnel inside the maintenance door of the equipment to be maintained, move the lighting unit on the moving unit to a set position or an initial position of the maintenance door of the equipment to be maintained, so as to realize the reset of the lighting unit.

[0043] Specifically, when there is no personnel activity inside the unit, the driving device 3 and the maintenance lamp 5 are located at the lowest position on the side of the maintenance door, and the signals of all the infrared sensing devices 4 are in a continuous and unbroken state. Here, continuous and unbroken means that the infrared sensing device 4 is in a working state.

[0044] In some embodiments, the moving unit includes: a frame on which the lighting unit can move. For example: the frame is arranged in the maintenance door of the equipment to be maintained and is a track for the movement of the maintenance lamp. The maintenance lamp can move on the track. The sensing device can sense the position where the maintenance personnel are located, denoted as the current position. The driving unit can drive the maintenance lamp to move on the moving unit so that the maintenance lamp moves to the current position, realizing the movement of the maintenance lamp following the maintenance personnel.

[0045] The frame includes a first-direction motion guide rail and a second-direction motion guide rail. The first-direction motion guide rail, such as a horizontal motion guide rail. The second-direction motion guide rail, such as a vertical motion guide rail.

[0046] Among them, the first-direction motion guide rail has more than one first guide rail (such as a horizontal guide rail). More than one of the first guide rails are arranged in the first direction, such as in the horizontal direction, and can provide a moving track in the first direction for the lighting unit.

[0047] The second-direction motion guide rail has more than one second guide rail (such as a vertical guide rail). More than one of the second guide rails are arranged in the second direction, such as in the vertical direction, and can provide a moving track in the second direction for the lighting unit.

[0048] More than one of the first guide rails and more than one of the second guide rails are cross-arranged, and the intersection point is a set node. The induction unit is provided at the set node, specifically a fixed induction unit. Of course, the induction unit is also provided on the lighting unit or the driving unit. In addition, the induction unit can also be provided at the maintenance door entrance of the equipment to be maintained.

[0049] Specifically, among them, the horizontal motion guide rail can be set to multiple according to needs, such as the first horizontal guide rail 21 and the second horizontal guide rail 22. The vertical motion guide rail can also be set to multiple according to needs, such as the first vertical guide rail 11, the second vertical guide rail 12, and the third vertical guide rail 13, etc. By setting a frame for the maintenance lamp to move, and using an infrared induction device to sense the position of the maintenance personnel, according to the sensed position, the driving device of the maintenance lamp is controlled to move the maintenance lamp to the position where the maintenance personnel are located, so as to realize the movement of the maintenance lamp following the maintenance personnel.

[0050] In some embodiments, more than one of the first guide rails and more than one of the second guide rails are vertically cross-arranged. More than one of the first guide rails include the first horizontal guide rail 21 and the second horizontal guide rail 22. More than one of the second guide rails include the first vertical guide rail 11, the second vertical guide rail 12, and the third vertical guide rail 13.

[0051] Among them, the induction unit is provided at each set node of the first horizontal guide rail 21, the second horizontal guide rail 22, the first vertical guide rail 11, the second vertical guide rail 12, and the third vertical guide rail 13, specifically a fixed induction unit.

[0052] The set nodes between the first horizontal guide rail 21 and the first vertical guide rail 11, the second vertical guide rail 12, and the third vertical guide rail 13 are the first node, the second node, and the third node in sequence.

[0053] The set nodes between the second horizontal guide rail 22 and the first vertical guide rail 11, the second vertical guide rail 12, and the third vertical guide rail 13 are the fourth node, the fifth node, and the sixth node in sequence.

[0054] Specifically, in the unit maintenance section, the first vertical guide rail 11, the second vertical guide rail 12, the third vertical guide rail 13, the first horizontal guide rail 21, and the second horizontal guide rail 22 are used to build the movement route map of the maintenance lamp 5. An infrared sensing device 4 is built at each node between the guide rails to ensure that infrared signals are transmitted at each node. The maintenance lamp 5 is combined with the driving device 3 and the infrared sensing device 4 to ensure that the driving device 3 can drive the maintenance lamp 5 to move horizontally and vertically in the guide rail and can sense the infrared signal. Among them, for the unit maintenance section, in each functional section of the combined air conditioner unit, if there is a part with a maintenance door, it is used as the unit maintenance section. Combining the maintenance lamp with the driving device 3 and the infrared sensing device 4 includes: assembling the driving device 3 and the infrared sensing device 4 together and configuring the maintenance lamp 5. It only needs to ensure that the three devices can be equipped on one module at the same time. Specifically, it can refer to the infrared sensing handwashing in the washroom.

[0055] In some embodiments, if a maintenance personnel enters the maintenance door of the equipment to be maintained, the first induction signal sent by the mobile induction unit in the induction unit is interrupted, and the lighting unit is in the on state. The fourth node is set at the maintenance door of the equipment to be maintained. Then, at the fourth node, if the second induction signal sent by the fixed induction unit in the induction unit is interrupted. And at the first node and the fifth node, if the second induction signal sent by the fixed induction unit in the induction unit is not interrupted, the driving device is used to move the lighting unit on the mobile unit to a position between the fourth node and the fifth node.

[0056] Specifically, when a maintenance personnel enters the unit, the infrared sensing signal of the infrared sensing device 4 on the driving device 3 is first interrupted, and the maintenance lamp 5 is automatically lit. When the low - level fourth node generates an interruption signal (that is, the infrared sensing signal of the infrared sensing device 4 at the fourth node is interrupted once, indicating that the person has walked through the fourth node but has not walked out of the fifth node), and the middle - level first node and the low - level fifth node are not interrupted, it indicates that the maintenance personnel are in the middle of the fourth node and the fifth node (the person should be between the fourth node and the fifth node), and the highest position does not exceed the middle - level node such as the first node. At this time, the driving device 3 automatically runs to the middle of the two fourth and fifth nodes until the signal is interrupted, ensuring that the maintenance lamp 5 is synchronized with the personnel position (that is, the lamp moves with the person) and ensuring the environmental illuminance.

[0057] Afterwards, at the fifth node and the second node, if the second induction signal sent by the fixed induction unit in the induction unit is interrupted. And at the first node, the third node, and the sixth node, if the second induction signal sent by the fixed induction unit in the induction unit is not interrupted, the driving device is used to move the lighting unit on the moving unit to a position between the second node and the third node.

[0058] Specifically, when interruption signals occur at both the low - level fifth node and the middle - level second node (indicating that the person climbs high and passes through the second node and the fifth node), and no interruption occurs at the first node, the third node, and the sixth node, it indicates that the maintenance personnel are in the middle (i.e., between) the second node and the third node. At this time, the driving device 3 automatically runs to the middle (i.e., between) the second node and the third node until the signal is interrupted, ensuring that the maintenance lamp 5 is synchronized with the personnel's position. The same condition applies when the number of nodes increases.

[0059] Afterwards, at the first node, the second node, the third node, the fourth node, the fifth node, and the sixth node, if the second induction signal sent by the fixed induction unit in the induction unit is not interrupted, the driving device is used to move the lighting unit on the moving unit from the sixth node to the fourth node until it moves to the inside of the maintenance door of the equipment to be maintained. Inside the maintenance door of the equipment to be maintained, if the first induction signal sent by the moving induction unit in the induction unit is not interrupted, the lighting unit is turned off.

[0060] Specifically, when there is no signal interruption at all nodes, the driving device 3 and the maintenance lamp 5 automatically run from the sixth node at the lowest position to the fourth node until they are close to the side of the maintenance door. If there is no signal interruption, it indicates that the maintenance personnel have left, and the maintenance lamp 5 automatically turns off until the next signal feedback. The maintenance lamp 5 can be provided with a power supply line on the frame to supply power to the maintenance lamp 5. The maintenance lamp 5 can also be a rechargeable lamp, which is charged at the set nodes or returns to the set charging position for charging after work.

[0061] In some embodiments, it further includes: a control unit.

[0062] Wherein, the control unit is configured to control the lighting unit to turn on when there is a maintenance personnel at the position where the induction unit is located or within a set range of the position where the induction unit is located. And control the lighting unit to turn off when there is no maintenance personnel at the position where the induction unit is located or within a set range of the position where the induction unit is located.

[0063] The control unit is further configured to control the driving unit to drive or carry the lighting unit to move on the moving unit in the case where the maintenance personnel move, so that the lighting unit moves on the moving unit to the position where the maintenance personnel are located or within a set range of the position where the maintenance personnel are located, realizing that the lighting unit follows the maintenance personnel to move.

[0064] For example: cooperating with an infrared sensing device, the maintenance lamp can achieve the automatic switching performance of turning on when people are present and turning off when people leave, increasing the intelligent control mode of the maintenance lamp.

[0065] Through a large number of experimental verifications, adopting the technical solution of the present invention, by setting a frame for the maintenance lamp to walk, and sensing the position where the maintenance personnel are located through an infrared sensing device, and controlling the driving device of the maintenance lamp to move the maintenance lamp to the position where the maintenance personnel are located according to the sensed position, realizing that the maintenance lamp follows the maintenance personnel to move. Thus, by enabling the maintenance lamp of large equipment to follow the maintenance personnel to move, the maintenance lamp can meet the lighting requirements of maintenance work even when the specifications of large equipment are too large.

[0066] According to an embodiment of the present invention, there is also provided a modular air handling unit corresponding to the lighting device for maintenance. The modular air handling unit may include: the lighting device for maintenance described above. The lighting device for maintenance is arranged in the maintenance door of the maintenance section of the modular air handling unit.

[0067] The specifications of large equipment, such as modular air handling units, are getting larger and larger. Due to maintenance requirements, the lighting requirements for internal maintenance of modular air handling units have correspondingly increased, and the illuminance index of the maintenance lamp has also been correspondingly improved. In related solutions, the maintenance lamps inside the modular air handling unit are all in fixed positions. When the specifications of the modular air handling unit are too large, the farther away from the maintenance lamp, the lower the light illuminance, which cannot meet the daily work needs of maintenance staff.

[0068] Considering that the maintenance lamps inside the modular air handling unit are all in fixed positions, when the specifications of the modular air handling unit are too large, the farther away from the maintenance lamp, the lower the light illuminance, which cannot meet the daily work needs of maintenance staff. In some solutions, the ways to improve the light illuminance are to increase the number of maintenance lamps and increase the power of the maintenance lamp. When increasing the number of maintenance lamps, the maintenance convenience is poor. When increasing the power of the maintenance lamp, the operating cost is increased and the problem of insufficient illuminance at the far lamp cannot be avoided.

[0069] Among them, the modular air handling unit is an air handling device assembled by various air handling function sections. For the detailed part, reference can be made to the national standard GB / T 14294-2008.

[0070] In some embodiments, the solution of the present invention provides a self-propelled maintenance lamp layout structure, which can adjust the position of the maintenance lamp relative to the personnel in real time according to the actual needs of the maintenance personnel, ensure that the maintenance lamp moves with the personnel, meet the illumination index requirements of the maintenance personnel's working environment, greatly reduce the configuration requirements of multiple maintenance lamps or high-power maintenance lamps inside large units, improve the maintenance convenience, and save the operation cost. Thus, it can solve the problem that the fixed position of the maintenance lamp inside a large unit (such as a packaged air conditioner unit) results in insufficient illumination at the position of the far lamp.

[0071] In the solution of the present invention, what is required for this self-propelled maintenance lamp layout structure is a frame for the maintenance lamp to move. It is necessary to have enough space inside the unit to build and install the moving frame of the maintenance lamp. Of course, in addition to the packaged air conditioner unit, other types of equipment can also use this structure, but the prerequisite is the same, that is, there must be enough space to install the maintenance lamp frame to ensure that there is sufficient space for the maintenance lamp walking device to move.

[0072] In the solution of the present invention, this self-propelled maintenance lamp layout structure, a self-propelled maintenance lamp and its control method that can automatically move relative to the maintenance personnel entering the unit can ensure the illumination requirements of the maintenance personnel's working environment and reduce the demand for other maintenance lamps; combined with an infrared sensing device, the maintenance lamp can achieve the automatic switching performance of turning on when people are present and turning off when people leave, increasing the intelligent control method of the maintenance lamp. Among them, this self-propelled maintenance lamp layout structure can be either independent of the equipment to be maintained or preset inside the unit in advance. As long as there is a maintenance requirement inside the equipment to be maintained and enough space for layout, it can be a combination of the two rather than being limited to only one of them.

[0073] Preferably, the solution of the present invention is mainly used by being preset inside the unit in advance, which is convenient for customers to directly use on-site. More preferably, this self-propelled maintenance lamp layout structure is attached to the packaged air conditioner unit and used as a part of the packaged air conditioner unit, and can also be used externally after being sold with the product.

[0074] The following combines Figures 2 to 4 the examples shown to exemplarily illustrate the specific implementation process of the solution of the present invention.

[0075] Figure 2 It is a schematic structural diagram of an embodiment of a self-propelled maintenance lamp layout structure. As Figure 2As shown in the figure, a self-propelled maintenance lamp layout structure includes: a horizontal movement guide rail, a vertical movement guide rail, a driving device 3, a maintenance lamp 5, and an infrared sensing device 4. Among them, multiple horizontal movement guide rails can be set as needed, such as the first horizontal guide rail 21 and the second horizontal guide rail 22. Multiple vertical movement guide rails can also be set as needed, such as the first vertical guide rail 11, the second vertical guide rail 12, and the third vertical guide rail 13, etc.

[0076] In Figure 2 In the example shown, first, in the unit maintenance section, the first vertical guide rail 11, the second vertical guide rail 12, the third vertical guide rail 13 and the first horizontal guide rail 21, the second horizontal guide rail 22 are used to build the movement route map of the maintenance lamp 5. An infrared sensing device 4 is built at each node between the guide rails to ensure that infrared signals are transmitted at each node; the maintenance lamp 5 is combined with the driving device 3 and the infrared sensing device 4 to ensure that the driving device 3 can drive the maintenance lamp 5 to move horizontally and vertically in the guide rail and can sense the infrared signal. Among them, for the unit maintenance section, in each functional section of the modular air handling unit, if there is a part with a maintenance door, it is used as the unit maintenance section. Combining the maintenance lamp with the driving device 3 and the infrared sensing device 4 includes: assembling the driving device 3 and the infrared sensing device 4 together, and configuring the maintenance lamp 5. It only needs to ensure that the three devices can be equipped on one module at the same time. Specifically, it can refer to the infrared sensing handwashing in the washroom.

[0077] Among them, the driving device can be a frame trolley structure. The trolley has a frame, and inside the frame are a motor and gears. The maintenance lamp is fixed on the top of the frame, and an infrared sensing device is installed beside the maintenance lamp. When the infrared sensing device at other nodes senses that the signal is interrupted by a person, it transmits a signal to the controller, and the motor starts to drive, controlling the gears to engage with the guide rail, driving the trolley to run along the guide rail until the infrared signal is interrupted and the motor stops running.

[0078] For example: a first infrared sensing device is built at the first node of the first vertical guide rail 11 and the first horizontal guide rail 21, a second infrared sensing device is built at the second node of the second vertical guide rail 12 and the first horizontal guide rail 21, a third infrared sensing device is built at the third node of the third vertical guide rail 13 and the first horizontal guide rail 21, a fourth infrared sensing device is built at the fourth node of the first vertical guide rail 11 and the second horizontal guide rail 22, a fifth infrared sensing device is built at the fifth node of the second vertical guide rail 12 and the second horizontal guide rail 22, and a sixth infrared sensing device is built at the sixth node of the third vertical guide rail 13 and the second horizontal guide rail 22.

[0079] In Figure 2In the example shown, when there is no personnel activity inside the unit, the driving device 3 and the maintenance lamp 5 are located at the lowest position on the maintenance door side, and all the signals of the infrared sensing devices 4 are in a continuous and unbroken state; among them, continuous and unbroken means that the infrared sensing devices 4 are in a working state.

[0080] In Figure 2 In the example shown, when maintenance personnel enter the inside of the unit, the infrared sensing signal of the infrared sensing device 4 on the driving device 3 is interrupted first, and the maintenance lamp 5 is automatically lit. When the low-position fourth node generates an interruption signal (that is, the infrared sensing signal of the infrared sensing device 4 at the fourth node is interrupted once, indicating that a person has walked through the fourth node but has not walked out of the fifth node), and the middle-position first node and the low-position fifth node are not interrupted, it indicates that the maintenance personnel are located between the fourth node and the fifth node (the person should be between the fourth node and the fifth node), and the highest point does not exceed the middle-position node such as the first node. At this time, the driving device 3 automatically runs to the middle of the two fourth nodes and the fifth node until the signal is interrupted, ensuring that the maintenance lamp 5 is synchronized with the personnel position (that is, the lamp moves with the person), and ensuring the environmental illuminance. The signal refers to the infrared induction signal. If there is no person blocking, the infrared signal is normal. If there is no feedback of the infrared signal, it proves that there is a person in the middle, then the signal is interrupted. The purpose is to ensure that the maintenance lamp and the personnel are always in the same position.

[0081] Among them, the signal of the infrared sensing device 4 on the driving device 3 is interrupted because the maintenance personnel enter from the maintenance door and block the infrared signal of the infrared sensing device 4 on the driving device 3, causing the infrared signal to be interrupted. For example: the signal reception of the infrared sensing device 4 is blocked. Specifically, the induction device of the washbasin can be used for reference. When a person's hand approaches, there is water, and when the hand leaves, the water stops because the signal is interrupted to ensure the synchronization of the device and the personnel.

[0082] The maintenance personnel are located between the fourth node and the fifth node, rather than between the first node and the fourth node, because: if the fourth node generates a continuous interruption signal, the maintenance personnel are between the first node and the fourth node. Because the originally assumed fourth node is at the shoulder height of an ordinary person (1.5 m from the bottom of the cabinet), and the height of the first node is 2.5 m. If the maintenance personnel climb and work between the first node and the fourth node, the signals of the first node and the fourth node will be interrupted simultaneously.

[0083] In Figure 2In the example shown, when interruption signals occur at both the fifth low - level node and the second middle - level node (indicating that the person climbs high and passes through the second node and the fifth node), and there are no interruptions at the first node, the third node, and the sixth node, it indicates that the maintenance personnel are between the second node and the third node. At this time, the driving device 3 automatically runs to the middle (i.e., between) the second node and the third node until the signal is interrupted, ensuring that the maintenance lamp 5 is synchronized with the personnel's position. The same condition applies when the number of nodes is increased.

[0084] In Figure 2 the example shown, when there is no signal interruption at all nodes, the driving device 3 and the maintenance lamp 5 automatically run from the sixth node at the lowest position to the fourth node until they are close to the side of the maintenance door. If there is no signal interruption, it indicates that the maintenance personnel have left, and the maintenance lamp 5 automatically turns off until the next signal feedback.

[0085] Figure 3 It is a schematic diagram of the control flow of an embodiment of a self - propelled maintenance lamp arrangement structure. As Figure 3 shown, a control flow of a self - propelled maintenance lamp arrangement structure includes:

[0086] Step 1: Determine whether the infrared sensing signal at the driving device 3 is interrupted. If so, control the maintenance lamp 5 to turn on; otherwise, end the current control.

[0087] Step 2: After controlling the maintenance lamp 5 to turn on, determine whether the infrared sensing signal at the fourth node is interrupted. If so, determine whether the infrared sensing signal at the first node is interrupted; otherwise, the driving device 3 carries the maintenance lamp 5 to the interruption point of the infrared sensing signal, and then determine whether the infrared sensing signal at the driving device 3 is interrupted: If the infrared sensing signal at the driving device 3 is interrupted, determine whether the infrared sensing signal at the first node is interrupted; if the infrared sensing signal at the driving device 3 is not interrupted, end the current control.

[0088] Step 3: After determining whether the infrared sensing signal at the first node is interrupted, if the infrared sensing signal at the first node is interrupted, the driving device 3 carries the maintenance lamp 5 to the interruption point of the infrared sensing signal, and then determine whether the infrared sensing signal at the driving device 3 is interrupted: If the infrared sensing signal at the driving device 3 is interrupted, determine whether the infrared sensing signal at the fifth node is interrupted; if the infrared sensing signal at the driving device 3 is not interrupted, end the current control; if the infrared sensing signal at the first node is not interrupted, directly determine whether the infrared sensing signal at the fifth node is interrupted.

[0089] Step 4. After determining whether the infrared sensing signal at the fifth node is interrupted, if the infrared sensing signal at the fifth node is interrupted, the driving device 3 drives the inspection lamp 5 to move to the interruption point of the infrared sensing signal, and then determines whether the infrared sensing signal at the driving device 3 is interrupted: if the infrared sensing signal at the driving device 3 is interrupted, determine whether the infrared sensing signal at the second node is interrupted; if the infrared sensing signal at the first node is not interrupted, determine whether the infrared sensing signal at the second node is interrupted.

[0090] Step 5. After determining whether the infrared sensing signal at the second node is interrupted, if the infrared sensing signal at the second node is interrupted, the driving device 3 drives the inspection lamp 5 to move to the interruption point of the infrared sensing signal, and then determines whether the infrared sensing signal at the driving device 3 is interrupted: if the infrared sensing signal at the driving device 3 is interrupted, determine whether the infrared sensing signal at the sixth node is interrupted; if the infrared sensing signal at the second node is not interrupted, determine whether the infrared sensing signal at the sixth node is interrupted.

[0091] Step 6. After determining whether the infrared sensing signal at the sixth node is interrupted, if the infrared sensing signal at the sixth node is interrupted, the driving device 3 drives the inspection lamp 5 to move to the interruption point of the infrared sensing signal, and then determines whether the infrared sensing signal at the driving device 3 is interrupted: if the infrared sensing signal at the driving device 3 is interrupted, determine whether the infrared sensing signal at the third node is interrupted; if the infrared sensing signal at the sixth node is not interrupted, determine whether the infrared sensing signal at the third node is interrupted.

[0092] Step 7. After determining whether the infrared sensing signal at the third node is interrupted, if the infrared sensing signal at the third node is interrupted, the driving device 3 drives the inspection lamp 5 to move to the interruption point of the infrared sensing signal, and then determines whether the infrared sensing signal at the driving device 3 is interrupted; if the infrared sensing signal at the third node is not interrupted, determine whether the infrared sensing signal at the driving device 3 is interrupted.

[0093] Step 8. After determining whether the infrared sensing signal at the driving device 3 is interrupted, if the infrared sensing signal at the driving device 3 is interrupted, control the inspection lamp 5 to remain in the on state, that is, control the inspection lamp 5 to continue to be lit; if the infrared sensing signal at the driving device 3 is not interrupted, control the inspection lamp 5 to turn off, and the driving device 3 is reset, that is, the driving device 3 moves back to the inside of the inspection door, such as moving to the front side of the fourth node (i.e., the side of the fourth node away from the fifth node).

[0094] Figure 4Schematic structural diagram of an embodiment of the maintenance section of a modular air handling unit. The maintenance door is a movable door frame provided on the functional section of the unit, which functions to ensure that maintenance personnel can enter the interior of the unit to complete the internal maintenance and fault repair of the unit equipment. For specific details, reference can be made to Figure 4 the example shown. In Figure 4 the example shown, there are also provided an EC fan mounting surface 6, a moisture-proof lamp 7, and a channel steel base 8. When the unit is operating, outdoor fresh air enters from the air inlet section, and air dust particles are removed through the primary filter section and the electrostatic precipitator section. Then, it passes through the cooling coil section for cooling and dehumidification. The middle section is reserved for maintenance. The supply fan section is the power section of the unit, where a fan is installed. When operating, the fan rotates to generate blowing force, sucking air volume from the outside and blowing it into the room. The silencer section is the noise reduction section of the unit, where a silencer is installed for noise elimination treatment. The air outlet section is the docking section of the unit for uniform air outlet.

[0095] Since the processing and functions achieved by the modular air handling unit of this embodiment are basically corresponding to the embodiments, principles, and examples of the device shown in the foregoing Figure 1 description, for the details not elaborated in the description of this embodiment, reference can be made to the relevant descriptions in the foregoing embodiments, and no further elaboration will be made here.

[0096] Through a large number of experimental verifications, by adopting the technical solution of the present invention, a frame for the maintenance lamp to move is provided, and the position of the maintenance personnel is sensed by an infrared sensing device. According to the sensed position, the driving device of the maintenance lamp is controlled to move the maintenance lamp to the position where the maintenance personnel are located, realizing that the maintenance lamp follows the maintenance personnel, ensuring that the maintenance lamp moves with the personnel, meeting the requirements of the illuminance index of the maintenance personnel's working environment, greatly reducing the configuration requirements for multiple maintenance lamps or high-power maintenance lamps inside large units, improving the maintenance convenience, and saving the operation cost.

[0097] According to an embodiment of the present invention, there is also provided a control method for a maintenance lighting device corresponding to a modular air handling unit, as shown in Figure 5 the flowchart of an embodiment of the method of the present invention shown. The control method for the maintenance lighting device may include: step S110 to step S130.

[0098] At step S110, control the sensing unit to send and receive the sensing signal, so as to sense whether there is an obstacle at the position where the sensing unit itself is located or within a set range of the position where the sensing unit itself is located by sending and receiving the sensing signal, and regard the obstacle as a maintenance personnel. Among them, if the sensing signal is interrupted, it is determined that there is a maintenance personnel at the position where the sensing unit itself is located or within a set range of the position where the sensing unit itself is located. If the sensing signal is not interrupted, it is determined that there is no maintenance personnel at the position where the sensing unit itself is located or within a set range of the position where the sensing unit itself is located.

[0099] At step S120, control the lighting unit to turn on the lighting unit itself when there is a maintenance worker at the position where the sensing unit is located or within a set range of its own position, so as to achieve lighting.

[0100] At step S130, control the driving unit to move the lighting unit on the moving unit to the position where the maintenance worker is located or within a set range of the position where the maintenance worker is located when the maintenance worker moves, so as to achieve the movement of the lighting unit following the maintenance worker.

[0101] Thus, by realizing the movement of the lighting unit following the maintenance worker, the position of the maintenance lamp relative to the person can be adjusted in real time according to the actual needs of the maintenance worker, ensuring that the maintenance lamp moves with the person, meeting the requirements of the illuminance index of the maintenance worker's working environment, greatly reducing the configuration requirements of multiple maintenance lamps or high-power maintenance lamps inside the large unit, improving the maintenance convenience, and saving the operation cost. Therefore, it can solve the problem of insufficient illuminance that cannot be avoided at the position of the far lamp due to the fixed position of the maintenance lamp inside the large unit (such as a combined air conditioner unit).

[0102] In some embodiments, the sensing unit includes a moving sensing unit and a fixed sensing unit. The sensing signal includes a first sensing signal sent by the moving sensing unit and a second sensing signal sent by the fixed sensing unit.

[0103] The following combines Figure 6 Another embodiment flow schematic diagram of the control method of the maintenance lighting device of the present invention shown further illustrates another specific process of the control method of the maintenance lighting device, including: step S210 to step S240.

[0104] Step S210, control the moving sensing unit to send and receive the first sensing signal, so as to sense whether there is a maintenance worker at the position where the moving sensing unit is located or within a set range of its own position by sending and receiving the first sensing signal. If the first sensing signal is interrupted, it is determined that there is a maintenance worker at the position where the moving sensing unit is located or within a set range of its own position. If the first sensing signal is not interrupted, it is determined that there is no maintenance worker at the position where the moving sensing unit is located or within a set range of its own position.

[0105] Step S220, control the lighting unit to turn on the lighting unit itself when there is a maintenance worker at the position where the moving sensing unit is located, so as to achieve lighting.

[0106] Step S230: Control the fixed induction unit. When the lighting unit is in the on state, send the second induction signal and receive the second induction signal. By sending and receiving the second induction signal, sense whether there is a maintenance personnel at the position where the fixed induction unit itself is located or within a set range of its own position. If the second induction signal is interrupted, it is determined that there is a maintenance personnel at the position where the fixed induction unit itself is located or within a set range of its own position. If the second induction signal is not interrupted, it is determined that there is no maintenance personnel at the position where the fixed induction unit itself is located or within a set range of its own position.

[0107] Step S240: Control the drive unit. When there is a maintenance personnel at the position where the fixed induction unit itself is located or within a set range of its own position, move the lighting unit on the moving unit to the position where the fixed induction unit itself is located or within a set range of its own position, so as to realize the movement of the lighting unit following the maintenance personnel.

[0108] For example: a mobile induction unit, such as an infrared sensing device 4 provided together with a maintenance lamp 5 and a driving device 3. A fixed induction unit, such as the first infrared sensing device to the sixth infrared sensing device provided on the frame. The mobile unit is such as the frame. The maintenance lamp 5, the driving device 3, the infrared sensing device 4 and the frame can form a self-propelled maintenance lamp layout structure. This self-propelled maintenance lamp layout structure, a self-propelled maintenance lamp and its control method that can automatically move relative to the maintenance personnel entering the interior of the unit, can ensure the illumination requirements of the maintenance personnel's working environment and reduce the need for other maintenance lamps.

[0109] In some embodiments, it further includes: controlling the drive unit. After moving the lighting unit on the moving unit to the position where the maintenance personnel is located or within a set range of the position where the maintenance personnel is located, if the induction unit senses that there is no maintenance personnel at its own position or within a set range of its own position within a set time period, move the lighting unit on the moving unit to a set position or an initial position of the maintenance door of the equipment to be maintained, so as to realize the reset of the lighting unit. That is, if the maintenance personnel leaves the maintenance door of the equipment to be maintained, that is, when there is no maintenance personnel inside the maintenance door of the equipment to be maintained, move the lighting unit on the moving unit to a set position or an initial position of the maintenance door of the equipment to be maintained, so as to realize the reset of the lighting unit.

[0110] Specifically, when there is no personnel activity inside the unit, the driving device 3 and the maintenance lamp 5 are located at the lowest position on the maintenance door side, and all the signals of the infrared sensing devices 4 are in a continuous and non-interrupted state. Here, continuous and non-interrupted means that the infrared sensing device 4 is in a working state.

[0111] Since the processing and functions implemented by the method of this embodiment are basically corresponding to the embodiments, principles and examples of the aforementioned maintenance lighting device, for the details not described in the description of this embodiment, reference can be made to the relevant descriptions in the aforementioned embodiments and will not be elaborated here.

[0112] Through a large number of experimental verifications, by adopting the technical solution of this embodiment, by setting a frame for the maintenance lamp to move, and using an infrared induction device to sense the position of the maintenance personnel, according to the sensed position, controlling the driving device of the maintenance lamp to move the maintenance lamp to the position where the maintenance personnel are located, realizing that the maintenance lamp moves following the maintenance personnel, it can solve the problem that the maintenance lamp in the large unit (such as a combined air conditioner unit) is fixed in position and the illuminance at the far lamp position cannot be avoided to be insufficient.

[0113] In summary, it is easy for those skilled in the art to understand that on the premise of no conflict, the above-mentioned advantageous ways can be freely combined and superimposed.

[0114] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
