[0057] The present invention provides a test system and method for an intelligent thermometer as Figures 1 - 13 shown. The test system and method mainly utilize the cooperation of the communication unit test module 5 and the communication connector 6 to enable the test terminal 7 to establish a connection with multiple shielding boxes 1, so that the test terminal 7 can obtain the costs, electrical performance, and communication performance of each meter inside the multiple shielding boxes 1.

[0058] Refer to Figure 2As shown in the figure, the test method of the intelligent heat meter mainly includes the following four steps:

[0059] The first step: Set the number of communication connectors 6 according to the number of shielding boxes 1. A wireless transmission chip is set in the communication connector 6.

[0060] The second step: The communication unit test module 5 regularly collects the fees, electrical performance, and communication performance of the heat meter 2, the electricity meter 3, and the gas meter 4. The communication unit test module 5 is a dual-mode type II collector.

[0061] The third step: Remotely send the fees, electrical performance, and communication performance of the heat meter 2, the electricity meter 3, and the gas meter 4 collected by the communication unit test module 5 to the test terminal 7 in a wireless communication manner through the communication connector 6. The test terminal 7 can be a computer.

[0062] The fourth step: Based on the reference of the basic data in the database of the test terminal 7, judge whether the electrical performance and communication performance of the heat meter 2, the electricity meter 3, and the gas meter 4 meet the requirements.

[0063] It should be noted that the shielding box 1 is used to shield electromagnetic interference, such as electromagnetic waves generated by lightning, radio interference, power converters, etc., so as to ensure the metering accuracy and stability of the heat meter 2, the electricity meter 3, and the gas meter 4; and the shielding box 1 can also protect the heat meter 2, the electricity meter 3, and the gas meter 4 from damage by the external environment. For example, being accidentally bumped, and extending the service life of the heat meter 2, the electricity meter 3, and the gas meter 4.

[0064] Reference Figure 4 As shown in the figure, a side-opening door 8 is provided in front of the shielding box 1, so that the equipment status can be easily viewed and inspected without affecting normal use, ensuring the normal operation and maintenance of the equipment; setting the heat meter 2, the electricity meter 3, and the gas meter 4 centrally in the shielding box 1 can make the home or office environment cleaner and more beautiful, improving the overall aesthetics and user experience.

[0065] In the prior art, the method for concentrating multiple meters in the shielding box 1 usually uses a multi-meter acquisition system to test the data and performance of each meter and send the data to the test terminal 7. However, due to the shielding effect of the shielding box 1, it may interfere with the transmitted data, resulting in inaccurate data. Therefore, in the present invention, the communication connector 6 is installed outside the shielding box 1, and an Ethernet communication connection is used between the communication connector 6 and the communication unit test module 5. Specifically, the communication connector 6 is installed on the box door 8, and the transmitting end of the wireless transmitting chip on the communication connector 6 is located on the side of the box door 8 away from the shielding box 1. In this way, the data tested by the communication unit test module 5 is transferred through the Ethernet to the communication connector 6 and then directly transmitted wirelessly from the transmitting end located outside the shielding box 1, so that the shielding box 1 will not interfere with the transmitted data and the data is relatively accurate.

[0066] Reference Figures 4 - 5 As shown in the reference Figures 4 - 5 , the test method for the intelligent heat meter proposed in the present invention includes a test system for the intelligent heat meter. The main component in the test system for the intelligent heat meter is the shielding box 1. Inside the shielding box 1, a first tray 101 and a second tray 102 are provided. The first tray 101 and the second tray 102 are distributed vertically. The first tray 101 is used to install the heat meter 2, the electric energy meter 3, and the gas meter 4, and the second tray 102 is used to install the communication unit test module 5. The communication unit test module 5 can monitor and test the usage fees, electrical performance, and communication performance of the heat meter 2, the electric energy meter 3, and the gas meter 4. The specific test method is the prior art and will not be elaborated here.

[0067] The test terminal 7 is located on the computers used by the user side and the supply side. After the communication unit test module 5 tests the electrical performance and communication performance of the heat meter 2, the electric energy meter 3, and the gas meter 4, the data is transmitted to the test terminal 7 through the communication connector 6. The user side and the supply side can view the electrical performance and communication performance of the corresponding heat meter 2, electric energy meter 3, and gas meter 4 through the computer to determine whether the electrical performance and communication performance meet the requirements.

[0068] Among them, the first tray 101 and the second tray 102 are both hollow plates. A plurality of heat dissipation holes 1011 are provided on the upper surfaces of the first tray 101 and the second tray 102, and a wind inlet 1012 connected to the air supply system inside the shielding box 1 is also provided on the first tray 101 and the second tray 102; the air supply system such as a blower, the output end of the air supply system is connected to the wind inlet 1012. Since the wind inlet 1012 is provided on the upper surface of the corresponding first tray 101 and second tray 102, the wind supplied by the air supply system will first blow on the inner bottom surface of the hollow plate, and then evenly blow out from above the corresponding first tray 101 and second tray 102 through the plurality of heat dissipation holes 1011, achieving the purpose of evenly dissipating heat from the heat meter 2, the electric energy meter 3, the gas meter 4, and the communication unit test module 5.

[0069] Reference Figure 4 , Figure 6 and Figure 13 As shown in

[0070] Considering the problem that the air outlet is prone to adhesion of dust and blockage, in the present invention, a rotating rod 10 is rotatably provided on the inner side surface of the box door 8. A plurality of wind plates 15 are fixedly provided on the rotating rod 10. The plurality of wind plates 15 are adjacent to each other and are staggered between adjacent wind plates 15 to form a V-shaped structure. A magnetic sheet 16 is fixedly provided at the end of the wind plate 15, and a rubber pad 17 is fixedly provided on the surface of the magnetic sheet 16. The first heat dissipation hole 13, the second heat dissipation hole 14 correspond to the wind plate 15, and the magnetic sheet 16 can be adsorbed at the mouth of the first heat dissipation hole 13 or the second heat dissipation hole 14.

[0071] When the wind force temperature inside the shielding box 1 is maintained in a stable state, the wind force is discharged from the corresponding first heat dissipation hole 13 or second heat dissipation hole 14. When the temperature of the wind force inside the shielding box 1 is greater than the set threshold, it may be because the first heat dissipation hole 13 or the second heat dissipation hole 14 is blocked, resulting in unsmooth wind force. Therefore, at this time, the wind force pressure will increase. After the wind force pressure increases, it will push the wind plate 15, causing the rotating rod 10 to rotate. During the rotation of the wind plate 15, the rubber pad 17 is used to scrape the mouth of the first heat dissipation hole 13 or the second heat dissipation hole 14, so that the blocked fluff and other sundries are cleared, achieving the purpose of automatic blockage cleaning when blocked.

[0072] After the blockage is cleared, the wind power returns to normal. Then, the magnetic sheet 16 at the end of the wind power plate 15 adsorbs at the mouth of the corresponding first heat dissipation hole 13 or second heat dissipation hole 14, serving the purpose of blocking the first heat dissipation hole 13 or second heat dissipation hole 14. By retaining any one group of the first heat dissipation hole 13 or second heat dissipation hole 14 for heat dissipation, it can ensure the heat dissipation efficiency while maintaining the temperature difference inside the shielding box 1 from being too large. When the first heat dissipation hole 13 or second heat dissipation hole 14 is blocked, the wind power plate 15 rotates again, switching to the first heat dissipation hole 13 and the second heat dissipation hole 14 for heat dissipation together. While quickly dissipating heat, the rubber pad 17 cleans the mouth of the first heat dissipation hole 13 or second heat dissipation hole 14.

[0073] In actual use, the end of the rubber pad 17 can also adopt a brush or a convex structure to facilitate dust cleaning.

[0074] Reference Figure 4 and Figure 5 As shown in

[0075] Specifically, as shown in Figures 6 - 12 In it, a second cable 12 is arranged on the communication unit test module 5, and a first cable 11 is arranged on the communication connector 6. The first cable 11 and the second cable 12 are connected through an adapter 9. The adapter 9 includes an adapter plate 91 and an adapter box cover 92. The adapter box cover 92 is fixedly connected to the adapter plate 91 by screws. One end of the adapter plate 91 is fixedly provided with a rotating connecting rod 93. A rotating seat 94 is fixedly installed on the inner wall of the shielding box 1. The end of the rotating connecting rod 93 away from the adapter plate 91 is rotatably connected to the rotating seat 94. A support frame 96 is rotatably arranged at one end of the bottom of the adapter plate 91 close to the rotating connecting rod 93. A sliding track 98 is fixedly installed on one side of the box door 8 close to the shielding box 1. A sliding groove 99 is arranged on the sliding track 98. A rotating shaft 97 is rotatably arranged at one end of the support frame 96 away from the adapter plate 91. The rotating shaft 97 is slidably arranged in the sliding groove 99. A transfer interface 95 is arranged on the adapter plate 91. There are multiple transfer interfaces 95, and the multiple transfer interfaces 95 are arranged at equal distances. A rectangular groove 90 is arranged on the adapter box cover 92. The rectangular groove 90 is arranged in the middle of the adapter box cover 92 and penetrates through the inner and outer surfaces of the adapter box cover 92.

[0076] Among them, the rectangular groove 90 allows the branch cable 111 on the first cable 11 to extend in actively. A plurality of clamps 1114 for clamping and fixing the branch cable 111 are fixedly arranged on the inner surface of the adapter box cover 92.

[0077] Wherein, the adapter 95 allows the end of the second cable 12 to extend therein and connect to the branch cable 111.

[0078] A limit card member 121 is fixedly arranged at the end of the second cable 12. The limit card member 121 includes two first magnetic plates 1211 and a rubber block 1212. The rubber block 1212 is fixed in the middle of the first magnetic plates 1211, and the width of the limit card member 121 is greater than the width of the adapter 95. One end of the branch cable 111 is fixedly provided with a stainless steel limit plate 1112, and the stainless steel limit plate 1112 is adsorbed and fixed on the first magnetic plate 1211. A card slot 122 is arranged at the end of the second cable 12, and a card head 1111 is arranged at the end of the branch cable 111. The card head 1111 is engaged in the card slot 122 to realize the electrical connection between the second cable 12 and the branch cable 111. When connecting the first cable 11 and the second cable 12, first, the limit card member 121 at the end of the second cable 12 is inserted into the adapter 95. When the limit card member 121 is inserted, the rubber block 1212 is squeezed and deformed, so that the limit card member 121 can normally extend from the adapter 95 between the adapter plate 91 and the adapter box cover 92. Then, the first magnetic plate 1211 is adsorbed and fixed on the inner surface of the adapter plate 91 by magnetic force, completing the fixation of the end of the second cable 12, which is convenient for installation.

[0079] Then, the branch cable 111 at the end of the first cable 11 is inserted between the adapter plate 91 and the adapter box cover 92 from the position of the rectangular groove 90. The branch cable 111 is clamped and fixed in the clamp 1114. At this time, the card head 1111 at the end of the branch cable 111 can be manually inserted into the card slot 122 first to complete the docking of the second cable 12 and the branch cable 111. Or the adapter box cover 92 can be fixed in the adapter plate 91 first. Since the length of the end of the branch cable 111 extending out of the clamp 1114 is limited, the first magnetic plate 1211 will automatically adsorb the corresponding stainless steel limit plate 1112, so that the card head 1111 is automatically engaged in the card slot 122, realizing the docking of the ends of the second cable 12 and the branch cable 111 and completing the electrical connection.

[0080] Moreover, due to the action of magnetic adsorption, the connection at the joint is stable. Further, a second magnetic plate 1113 is fixedly installed on the inner wall of the adapter box cover 92. The second magnetic plate 1113 repels the first magnetic plate 1211. When the second cable 12 and the branch cable 111 are docked, the repulsive force between the second magnetic plate 1113 and the first magnetic plate 1211 can also keep the joint of the second cable 12 and the branch cable 111 stable, avoiding loosening and ensuring stable data transmission.

[0081] When the box door 8 is opened, the sliding track 98 moves along with the box door 8. At this time, the rotating shaft 97 is pulled by the sliding track 98 to rotate, and the adapter 9 can rotate along the position where the rotating connecting rod 93 is rotatably connected to the rotating seat 94, achieving the purpose of automatically extending the adapter 9. After extension, the adapter 9 pulls and arranges multiple second cables 12 clearly and neatly, which is convenient for inspection and maintenance. When the connection between the branch cable 111 and the second cable 12 becomes loose, the second cable 12 or the branch cable 111 will directly detach from the adapter 9, and the loose position can also be quickly determined, achieving the purpose of rapid repair.

[0082] When the box door 8 is closed, due to the push of the sliding track 98, the adapter 9 extends into the shielding box 1. The adapter 9 protects the connection between the second cable 12 and the branch cable 111, avoiding interference with other components inside the shielding box 1. It has strong protection and ensures neat wiring without manual cable arrangement and installation.
