Description

[0002] At present, communication companies vigorously develop FTTO (fiber to the office, an access mode using optical fiber transmission medium to connect communication station and company or office user) business for small and medium-sized enterprise customers, and products adopt master-slave gateway equipment for networking (for example, master gateway Huawei B866+ slave gateway B671), use gigabit WiFi technology (wireless local area network (WLAN) communication technology based on IEEE 802.11 standard), transmit WiFi signals through slave gateway, meet the demand of users for wireless coverage of gigabit use in different scenes. According to different user use scenes, slave gateway can be expanded to 32 at most, and the maximum coverage is 3000 square meters, and each set of equipment supports the use demand of 300 people working at the same time.

[0003] Because there are many slave gateway points, designers need to carry out on-site engineering reconnaissance and point planning and design for specific scenes. In order to ensure the accuracy of design, the test means currently adopted needs to simulate the real installation environment by manual simulation. However, according to the installation construction specification, slave gateway generally adopts ceiling or wall hanging mode, and the installation height is generally between 4-6 meters. At the same time, the AP (Access Point, wireless access point) equipment used for testing needs to use user environment power supply, and the signal strength test can be carried out only after power-on. Therefore, at least 2-3 people need to use ladders to carry out on-site test when simulating manually, which is time-consuming and laborious. In addition, during the signal strength test, slave gateway power-on test is based on user environment, and engineering reconnaissance personnel need to be equipped with multiple types of length power lines for equipment power-on, so they are greatly limited by cables and environment. In addition, due to the time-consuming and laborious process and the limitation, it is difficult to move and change flexibly. Once the point planning and design deviates, it cannot meet the signal strength and rate use demand in complex scenes, which affects the user's use perception. UTILITY MODEL CONTENT

[0025] EMBODIMENT

[0026] As Figure 1As shown, the WLAN wireless network survey tool of the embodiment includes a clamping part 1, an extension part 2 and a supporting part 3, the clamping part 1 is provided with a device mounting position and a power supply mounting position, a test AP device 5 for testing WLAN wireless network and a power supply 6 are respectively installed in the device mounting position and the power supply mounting position, the extension part 2 is connected to the supporting part 3 at the bottom and is supported on the ground at the survey position through the supporting part 3, and is connected to the clamping part 1 at the top, the extension part 2 can be extended in the vertical direction to adjust the height of the clamping part 1 carrying the test AP device 5.

[0027] In the case of testing WLAN wireless network, the embodiment no longer uses the traditional method of fixing the wireless test AP device 5 at the predetermined installation position by adhesive tape and ladder, and then pulling the test AP device 5 to the power supply at the user site through network cable or optical fiber composite cable for power supply, but proposes a WLAN wireless network survey tool for clamping and height adjustment of the test AP device 5. Specifically, the test AP device 5 and the power supply 6 for supplying power to the test AP device 5 are installed on the clamping part 1, and are supported on the ground at the survey position through the supporting part 3, and the height of the clamping part 1 is adjusted through the extension part 2.

[0028] The survey tool can flexibly adjust the height of the clamping part 1, so as to hold the test AP device 5 to the target installation height, which is more convenient and safe than manual holding or adhesive attachment, and is more convenient to carry than a ladder. In addition, the power supply mounting position is also provided, so that the test AP device 5 can be powered by the carried power supply 6, and the power supply problem of the wireless AP can be solved without re-laying the power supply line for testing. Therefore, the laying and adjustment operation during the survey is not limited by the length of the cable and the environment, and is more flexible and practical. The power supply 6 and the test AP device 5 are installed on the clamping part 1, and the arrangement position is designed reasonably, and the cable 7 between the two will not affect the support of the supporting part 3 and the extension of the extension part 2. Due to the aforementioned convenience, the survey tool saves labor and time cost, and the work that previously required 2-3 people can now be completed by one person, and the WIFI survey personnel can set up a real installation scene of the wireless AP on site.

[0029] In the embodiment, the test AP device 5 is a conventional WLAN wireless network test device, the power supply 6 can use a lithium battery, and the cable 7 can use a conventional power supply cable on the market, which will not be described in detail here.

[0030] In the embodiment, as shown in Figure 2 and Figure 3As shown, the clamping part 1 comprises a connecting plate 11 and two pressing plates 12, which are respectively connected to opposite ends of the connecting plate 11 and are perpendicular to the plane of the connecting plate 11, so that the two pressing plates 12 and the connecting plate 11 together form a half-enclosed structure with three side surfaces, i.e. a "concave" structure with an open top, as shown. Figure 1 As shown, the left vertical pressing plate 12, the middle horizontal connecting plate 11 and the right vertical pressing plate 12 together form a "concave" structure with an open top.

[0031] Since the AP device 5 for testing is connected to the top wall or side wall of the surveying position when installed, the area enclosed by the half-enclosed structure in this embodiment is used as a device installation position, and the AP device 5 for testing is installed in the device installation position, with both sides abutting the pressing plates 12 and the top surface abutting the connecting plate 11, so that the bottom surface can be exposed on the side of the open top of the device installation position and can be used as a mounting surface facing outward of the device installation position to abut the top wall or side wall of the surveying position. The power supply 6 is installed on one side of the AP device 5 for testing as a power supply installation position by using the surface of the pressing plate 12 facing outward of the connecting plate 11, and is connected to the AP device 5 for testing through the cable 7. In this layout, the clamping part 1 itself does not contact the mounting surface of the AP device 5 for testing, so that the AP device 5 for testing can accurately simulate the actual situation of being ceiling-mounted or wall-mounted, and the power supply 6 is installed on one side of the AP device 5 for testing instead of the top surface, which is not only aesthetically pleasing but also facilitates adjustment of the surveying tool, and can effectively avoid affecting the wireless signal. It can be seen that the layout is reasonable.

[0032] In this embodiment, the clamping part 1 further comprises a movable rod 13 and an elastic member 14, the movable rod 13 is movably connected to the connecting plate 11 along the connecting line direction of the two pressing plates 12 and is pulled tight to the center of the connecting plate 11 by the elastic member 14, and at least one pressing plate 12 is connected to the connecting plate 11 through the movable rod 13, so that the pressing plate 12 can move close to or away from the other pressing plate 12.

[0033] In this embodiment, the connecting plate 11 is provided with a blind hole along the connecting line direction of the two pressing plates 12 (i.e. the left-right direction in the figure), the movable rod 13 is arranged in the blind hole, the elastic member 14 can be a spring and is also arranged in the blind hole of the connecting plate 11, the blind hole is provided with a limiting member 16 at the opening of the blind hole, the limiting member 16 is smaller than the opening of the blind hole to avoid affecting the protrusion of the movable rod 13, one end of the movable rod 13 protrudes from the opening of the blind hole and is connected to the pressing plate 12, the other end of the movable rod 13 protrudes into the bottom of the blind hole, and the end portion protruding into the bottom of the blind hole is connected to the limiting member 16 through the elastic member 14, so as to realize the tension to the center through the elastic force. In the normal state, the spring pulls the movable rod 13 into the hole, thereby pulling the pressing plate 12 to the center of the connecting plate 11 (for example, pulling the left pressing plate 12 to the right side, and pulling the right pressing plate 12 to the left side), so as to clamp the AP device 5 for testing. When the person is subjected to the outward pulling force, the pressing plate 12 is pulled out to the outside of the connecting plate 11, thereby releasing the AP device 5 for testing or allowing the AP device 5 for testing to be installed. The movable pressing plate 12 can not only more stably clamp the AP device 5 for testing, but also can be used for various specifications of the AP device 5 for testing. In this embodiment, both of the two pressing plates 12 can be moved by the movable rod 13, and in other embodiments, a single pressing plate 12 can be fixed and the other pressing plate 12 can be movable.

[0034] In this embodiment, the clamping part 1 further comprises a battery box 15, the battery box 15 is connected to the pressing plate 12 and is located at the surface of the pressing plate 12 facing the outside of the connecting plate 11, and the battery box 15 is internally provided with a containing area as a power supply mounting position for accommodating the power supply 6. The battery box 15 can also be provided with a wire passing hole according to needs, so that the cable 7 can pass through.

[0035] In this embodiment, the WLAN wireless network survey tool further comprises a universal joint 4, and the clamping part 1 is connected to the top end of the telescopic part 2 through the universal joint 4. Due to the arrangement of the universal joint 4 structure, the clamping part 1 can be turned over at the top end of the telescopic part 2, so as to freely adjust the direction angle of the AP device 5 for testing, and can present a real wall hanging or ceiling effect. The universal joint 4 used in this embodiment is a conventional mechanical structure (also called universal joint or standard small tripod) on the market, and the interface conversion between the universal joint 4 and the telescopic part 2 can be realized through a conversion screw. The connection mode of the universal joint 4 with the clamping part 1 and the telescopic part 2 is a conventional connection form of the structure, so it is not described here. The connecting plate 11 can be provided with a connecting hole 17 at the position between the two blind holes (non-opening area) to connect the universal joint 4.

[0036] In the embodiment, the telescopic part 2 comprises a plurality of sleeves, each of which is sleeved with the other from inside to outside, that is, the second sleeve is sleeved outside the first sleeve, the third sleeve is sleeved outside the second sleeve, and so on. In each group of two sleeves sleeved with each other, the inner sleeve extends from the same side port of the outer sleeve (that is, the first sleeve extends from the top opening of the second sleeve, the second sleeve extends from the top opening of the third sleeve, and so on, the inner sleeve extends from the top opening of the outer sleeve), and can be axially telescopic at the port to adjust the overall length of the telescopic part 2. In the embodiment, the number and size of the sleeves can be selected according to the actual environment, load requirements, etc. During adjustment, the survey personnel can adjust the overall length of the telescopic part 2 by hand by adjusting the length of each sleeve extending out according to the required height. The telescopic part 2 adopted in the embodiment can extend up to 6 meters and retract to 1 meter at the lowest, and can be completely applied to various indoor office application scenarios.

[0037] In the embodiment, in each group of two sleeves sleeved with each other, the outer surface of the inner sleeve and the inner surface of the outer sleeve are provided with mutually adapted threads, and the inner sleeve and the outer sleeve are relatively extended or retracted along the threads by rotation. This threaded connection form can not only achieve stepless adjustment of the telescopic length, but also can ensure that the structure can be kept at the current position after adjustment, that is, self-locking fixation after length adjustment through the friction force between the structures. This structure is a telescopic rod structure that already exists in the market, so it will not be described here and is not shown in the drawings.

[0038] In the embodiment, the telescopic part 2 comprises a plurality of sleeves, each of which is sleeved with the other from inside to outside, that is, the second sleeve is sleeved outside the first sleeve, the third sleeve is sleeved outside the second sleeve, and so on. In each group of two sleeves sleeved with each other, the inner sleeve extends from the same side port of the outer sleeve (that is, the first sleeve extends from the top opening of the second sleeve, the second sleeve extends from the top opening of the third sleeve, and so on, the inner sleeve extends from the top opening of the outer sleeve), and can be axially telescopic at the port to adjust the overall length of the telescopic part 2. In the embodiment, the number and size of the sleeves can be selected according to the actual environment, load requirements, etc. During adjustment, the survey personnel can adjust the overall length of the telescopic part 2 by hand by adjusting the length of each sleeve extending out according to the required height. The telescopic part 2 adopted in the embodiment can extend up to 6 meters and retract to 1 meter at the lowest, and can be completely applied to various indoor office application scenarios.

[0039] In the embodiment, the support part 3 comprises a first connecting sleeve 31, a second connecting sleeve 32, a plurality of legs 33, and a plurality of connecting rods 34. The first connecting sleeve 31 and the second connecting sleeve 32 are coaxially arranged and are both sleeved outside the telescopic part 2. The second connecting sleeve 32 is located below the first connecting sleeve 31. Each of the legs 33 is evenly distributed around the axis of the first connecting sleeve 31 and is hingedly connected to the top end of the first connecting sleeve 31. Each of the connecting rods 34 is hingedly connected to the middle part of the second connecting sleeve 32. The second connecting sleeve 32 is lowered away from the first connecting sleeve 31 along the telescopic part 2 to drive the connecting rods 34 to open the legs 33 to achieve support. The second connecting sleeve 32 is raised to approach the first connecting sleeve 31 along the telescopic part 2 to drive the connecting rods 34 to close the legs 33.

[0040] In this embodiment, the three legs 33 are used, and the corresponding connecting rods 34 are also used, that is, the support part 3 as a whole is in a tripod structure, and this support mode can stably support the entire tool on the ground at the survey position, and is also relatively convenient to fold and convenient for personnel to carry.

[0041] In summary, based on the background of the FTTO wireless network product being vigorously promoted for use, the FTTO gateway point design by experience will have errors, in order to make the point design more reasonable, only the real installation environment is simulated for testing. In view of the foregoing, the foregoing survey tool effectively solves how to send the device to a height of about 3 meters, how to power, how to realize two mainstream installation modes (wall hanging and ceiling suction) from the gateway, how to realize one person to complete the test and survey and a series of problems.

[0042] The WLAN wireless network survey tool is independently developed in this embodiment, which solves many problems such as installation height, direction angle adjustment, and device power supply in gateway signal strength testing. The power supply problem is solved by adding an external lithium battery power supply 6, which can present a real wall hanging or ceiling suction effect. The standing problem of the telescopic part 2 is solved by adding a tripod, the tool is flexible and convenient to carry, realizes one-person accurate survey, the weight is less than 0.5 kg, the overall weight is less than 1 kg, the height after retraction is less than 1 meter, and the telescopic length is 6 meters, which is convenient for survey personnel to carry in real time, reduces the tool load of personnel, greatly improves the support efficiency and survey accuracy, and can improve the work efficiency.

[0043] Specifically, the tool includes a tripod, a telescopic rod, a rechargeable 12V lithium battery and a 220V voltage output power supply line, a universal joint, and a clamping part. The telescopic part (or telescopic rod, telescopic net rod) is used to freely extend the test AP device 5 at the desired height, and the length can be flexibly adjusted. The clamping part 1 (or fixed clamp) is used to fix the test AP device 5, so that it does not fall in the case of severe shaking. And the clamping part 1 is used to fix the device by clamping, which is more secure and stable than the suction cup and adhesive, and is also more suitable for special structure gateway devices such as arc; the side position of the clamping part 1 is used as the power installation position, which effectively avoids affecting the wireless signal of the device while ensuring the appearance and practicability.

[0044] Lithium battery power supply 6 is used for powering the test AP device 5, which can output 12V 1.5A current, and 3000mAh power can ensure that the test AP device 5 works for a long time; the cable 7 (or power extension line) is used to extend the battery power line, which is convenient for the test AP device 5 to be powered at different angles; the universal joint 4 is used to connect the clamping part 1, and at the same time, the orientation of the test AP device 5 is adjusted, such as ceiling or wall hanging, the conversion screw of the universal joint 4 is used for the interface conversion between the universal joint and the telescopic rod, so that the two can be combined; the support part 3 (or tripod, three-legged support) is used to support the whole tool to prevent it from falling, and a person can set up a real installation scene. The combination of each component forms the landing of the WIFI engineering tool. The selection of each component is based on the actual working conditions on site. It has been verified that the engineering tool is very practical, saves labor cost, and improves the efficiency of WIFI survey.

[0045] In use, according to the height of the suspended ceiling on site, the lithium battery connected to the gateway (test AP device 5 connected to power supply 6) is connected, and then the telescopic part 2 is extended to the corresponding height for measurement, and the telescopic part 2 can be fixed or extended by rotating. In the case of one person on site, the tripod at the bottom of the telescopic part 2 can be opened, so that the tool does not fall. After connecting the WIFI signal of the gateway, the WIFI magic box APP can be used to measure and record the signal strength of different positions, and finally a reasonable point layout is planned (this measurement and recording process and the software used are not part of the tool scheme, and will not be described in detail here).

[0046] The following implementation cases are also provided in this embodiment:

[0047] As shown in Figure 4 , a hospital uses FTTO products for wireless coverage. Since it involves many floors of buildings, in order to ensure accurate point design, the engineering tool is used to simulate a real installation scene on site to measure the WIFI signal strength of each room, ensuring that the signal strength of each room is above -65dB, meeting the user's good network experience. Through the use of the engineering tool, the layout of the points becomes more reasonable, saving time and labor costs on site.

[0048] The WLAN wireless network survey tool of the embodiment can be matched with signal test software to realize signal strength test at any position in the surveyed environment. The tool is light and flexible, and meets the power supply problem of the device by means of lithium battery power supply, solves the problems of fixing and direction angle adjustment of the gateway device by means of the clamping part and universal joint, solves the problem of standing of the telescopic rod by means of the tripod, meets the signal strength test requirements and various complex surveying needs. The combination of the telescopic part and the tripod ensures that the FTTO can test the height from the gateway and the standing of the telescopic part. These features enable the tool to meet the needs of device installation and personnel independent surveying of buildings of different heights. The universal joint with adjustable direction and the clamping part enable the tool to meet the fixing of the gateway and signal emission test at different angles, and improve the accuracy of surveying. The tool is mainly used to assist the test AP device 5 in testing the WIFI signal strength to ensure the signal quality of wireless coverage, so the test AP device 5 can be matched with part of the mobile phone software APP. The tool is used to send the AP to be tested to the specified installation height and supply power to the AP device, so that the AP device can emit wireless signals. At this time, the mobile phone signal strength test APP is used to test the wireless signal strength emitted by the wireless AP, so as to obtain the signal coverage quality and effect of the area to be covered. Finally, the tool can be used in combination with the wireless AP and the signal strength test APP, but the specific software and test content are not within the scope of the embodiment.

[0049] Through the foregoing structure, the survey tool can achieve the following excellent effects:

[0050] 1. Flexible and accurate point planning, meeting the use needs of users and improving the service image of surveying;

[0051] 2. Simplifying the workload of personnel, enabling one person to accurately survey, improving work efficiency, and saving labor cost;

[0052] 3. The survey tool is flexible and light, and can be flexibly changed in angle according to the decoration environment on site, so as to realize ceiling or wall hanging of the wireless AP;

[0053] 4. Reducing the safety risk of personnel climbing.

[0054] It can be understood that the above embodiments are only exemplary embodiments adopted for illustrating the principles of the utility model, and the utility model is not limited to this. For ordinary skilled persons in the art, various modifications and improvements can be made without departing from the spirit and essence of the utility model, and these modifications and improvements are also regarded as the protection scope of the utility model.
