[0033] The utility model provides a multi-interface air-conditioning flexible control protocol conversion gateway, which needs to connect several different air conditioners during use and can obtain corresponding operating parameters from these air conditioners to facilitate analysis and calculation of these operating parameters, so as to realize flexible adjustment of different air conditioners according to actual needs; the flexible adjustment here is to make rapid adjustment according to the load change of the power system to ensure the safe and stable operation of the power system, mostly to achieve the demand for stable power consumption by reducing the power consumption of a certain area, and the opposite of flexible adjustment is one-size-fits-all or power outage (i.e. complete power outage).

[0034] like Figure 1 - Figure 8A multi-interface air-conditioning flexible control protocol conversion gateway is shown, comprising a housing 10 and a plurality of circuit boards 20 arranged in the housing 10, wherein the plurality of circuit boards 20 are arranged in parallel from top to bottom, that is, the circuit boards 20 are arranged in layers in the housing, and each layer has a certain distance between them, and two adjacent circuit boards 20 are electrically connected, and the electrical connection here can be connected by cables, and in the present application, a vertical circuit board (vertical circuit board 30) is used to realize the electrical connection between two adjacent parallel circuit boards 20, and the vertical circuit board 30 can also play a supporting role; some of the electrical components can also be arranged on the vertical circuit board 30, thereby improving the space utilization rate of the circuit board 20, and enabling the network The volume of the device is reduced; wherein each parallel circuit board 20 is fixed in the housing 10, and can be fixed by bolts or glue; wherein at least one parallel circuit board 20 is provided with a plurality of wiring terminals 40, and a plurality of holes 111 are opened on the housing 10, and the number of the plurality of holes 111 is consistent with the number of the wiring terminals 40 and corresponds to and is aligned one by one; a plurality of chambers connected to each other are formed from bottom to top inside the housing 10, and the chambers are gradually reduced from bottom to top; each of the chambers has a parallel circuit board 20, and the holes 111 corresponding to the wiring terminals 40 on the circuit board 20 are located on the housing 10 of the corresponding chamber.

[0035] like Figure 4 As shown, at least a processing module, a protocol conversion module and a control module are arranged on the circuit board 20, wherein the protocol conversion module is connected to the terminal 40 to receive the operating parameter signal of the air conditioner and convert the signal into a recognizable universal signal and transmit it to the processing module, and the signal is analyzed and processed in the processing module and then sent to the control module. The control module is respectively connected to the terminal 40 and the protocol conversion module. The control module can communicate the universal signal with other devices through the terminal 40, and at the same time, it can send a control signal to the air conditioner, which is converted into a signal recognizable by the air conditioner through the protocol conversion module, so as to flexibly adjust the air conditioner.

[0036] In the present application, the chambers are set to three, and the corresponding horizontally arranged circuit boards 20 are also three, and the vertical circuit boards 30 are two; the three chambers are respectively the first chamber, the second chamber and the third chamber from bottom to top; the shell 10 is divided into a base 11 and an upper cover 12, and the base 11 is used to fix the gateway device of the utility model to a wall or a power supply cabinet, and the upper cover 12 is buckled on the base 11, and the upper cover 12 and the base 11 can be fixed by using a card and a slot or by bolts. The upper cover 12 includes a first shell 121, a second shell 122 and a third shell 123. The first shell 121 and the base 11 are buckled to form a first chamber. The second shell 122 is located above the first shell 121, and the interior of the second shell 122 is the second chamber. The third shell 123 is located above the second shell 122, and the interior of the third shell 123 is the third chamber. The first shell 121, the second shell 122 and the third shell 123 are integrally formed by injection molding, so that the first chamber, the second chamber and the third chamber are all connected.

[0037] like Figure 1 and Figure 2 As shown, the two opposite sides of the first shell 121 and the second shell 122 are step transitions 124, that is, the connection between the first shell 121 and the second shell 122 is a step surface (first step surface); the two opposite sides of the second shell 122 and the third shell 123 are also step transitions 124, that is, the connection between the second shell 122 and the third shell 123 is also a step surface (second step surface); further, the above-mentioned step surfaces are all inclined, and the inclination angle is controlled at 1°-5°, preferably 3° in the present application; in the first step surface, the side in contact with the first shell 121 is lower than the side in contact with the second shell 122; in the second step surface, the side in contact with the second shell 122 is lower than the side in contact with the third shell 123; the step surface can also be designed as an arc surface; the setting of the inclined or arc-shaped step surface increases the operating range and is more comfortable when wiring, and at the same time makes the device rounder and more beautiful.

[0038] The top 126 of the third shell 123 is designed to be arc-shaped, and a display screen 50, an input setting button 60 and a working indicator light 70 are set on the top 126 of the third shell 123 to display the working status and facilitate input settings of the device, which can facilitate operation by operators.

[0039] As an embodiment of the present application, Figure 1 and Figure 2As shown, there are two groups of transition surfaces relatively set between the first shell 121 and the second shell 122, one group of transition surfaces relatively set is a step transition 124, and the other group of transition surfaces relatively set is a straight surface transition 125 (that is, the two side surfaces of the first shell 121 and the second shell 122 are located in the same plane); there are two groups of transition surfaces relatively set between the second shell 122 and the third shell 123, one group of transition surfaces relatively set is a step transition 124, and the other group of transition surfaces relatively set is a straight surface transition 125 (that is, the two side surfaces of the second shell 122 and the third shell 123 are located in the same plane).

[0040] Furthermore, the straight surface transition 125 between the first shell 121 and the second shell 122 and the straight surface transition 125 between the second shell 122 and the third shell 123 are located in the same plane, that is, the side surfaces of the first shell 121, the second shell 122, and the third shell 123 located on the same side are a whole side surface.

[0041] A fixing structure for fixing to other components is provided at the bottom of the shell 10, where the bottom of the shell 10 is the bottom of the base 11, and the other components may be a wall or a guide rail installed on the wall. The guide rail is formed by bending a sheet metal part, the middle of which is used to be fixed to the wall, and both sides can be snapped into the fixing structure.

[0042] In order to achieve quick installation with the guide rail, such as Figure 5 and Figure 6 The fixing structure shown in the present application includes a fixing groove 113 arranged on the base 11, a fixing rib 114 located on one side of the fixing groove 113 and extending into the fixing groove 113, and an elastic rib 80 located on the other side or both sides of the fixing groove 113 and extending into the fixing groove 113; a guide rail is passed through the fixing groove 113, the fixing rib 114 can be inserted into one side of the guide rail, and the elastic rib 80 can be inserted into the other side of the guide rail, so as to achieve quick installation; and the elastic rib The outward side of 80 is a slope. When the gateway device is inserted into the guide rail, the slope first contacts the guide rail to push the elastic retaining edge 80 backward to open it. After the guide rail passes over the elastic retaining edge 80, the elastic retaining edge 80 returns to its original position, which can block the guide rail from easily falling off. When the fixed retaining edge 114 is used, the elastic retaining edge 80 must be provided on the other side opposite to the fixed retaining edge 114 for normal use. The fixed retaining edge 114 can also be not used, and elastic retaining edges 80 can be used on both sides of the fixed groove 113.

[0043] In order to limit the position of the elastic retaining edge 80, a sliding groove 115 is arranged next to the fixed groove 113. The sliding groove 115 is perpendicular to the fixed groove 113. The elastic retaining edge 80 is arranged in the sliding groove 115, and its movement direction is perpendicular to the fixed groove 113; both sides of the sliding groove 115 extend into the interior of the sliding groove 115 to form a limiting plate 116, and the elastic retaining edge 80 is arranged below the limiting plate 116 to ensure that the elastic retaining edge 80 will not detach from the sliding groove 115.

[0044] like Figure 6 and Figure 7 The elastic retaining edge 80 shown in the figure includes a retaining edge body 81 arranged in the sliding groove 115 and elastic rods 82 arranged on both sides of the retaining edge body 81. The first end of the retaining edge body 81 can extend into the fixed groove 113. The elastic rod 82 is inclined relative to the retaining edge body 81. A receiving groove is arranged on the inner side of the sliding groove 115. The end of the elastic rod 82 is located in the receiving groove. The receiving groove has an inclined surface. The receiving groove cooperates with the end of the elastic rod 82. When the retaining edge body 81 is subjected to external force and moves in a direction away from the fixed groove 113 (that is, the elastic retaining edge 80 retracts), the elastic rod 82 swings in a direction close to the retaining edge body 81 due to the cooperation of the inclined surface of the receiving groove to store elastic potential energy. When the external force on the retaining edge body 81 disappears, the elastic rod 82 resets to release the elastic potential energy so that the retaining edge body 81 moves in a direction close to the fixed groove 113, thereby realizing the function of locking the guide rail.

[0045] However, during actual use, the above-mentioned guide rail may not exist, and in this case, the gateway device needs to be directly fixed; therefore, based on the above-mentioned fixing structure, the present application has been further optimized, and the elastic retaining edge 80 is arranged on both sides of the fixing groove 113, and the second end of the retaining edge body 81 can extend out of the sliding groove 115 and protrude from the shell 10, and at the same time, a fixing hole 83 is opened on the second end of the retaining edge body 81; the receiving groove is provided with two first receiving grooves 117 close to the fixing groove 113 and the second receiving groove 118 away from the fixing groove 113; when the end of the elastic rod 82 is located in the first receiving groove 117, the retaining edge body 81 cooperates with the guide rail To achieve fixation, the second end of the side retaining body 81 does not protrude from the shell 10; when the end of the elastic rod 82 is located in the second accommodating groove 118, the second end of the side retaining body 81 protrudes from the shell 10 and exposes the fixing hole 83, and is fixed and installed by screws and the fixing hole 83; the two installation methods can be achieved by driving the movement of the side retaining body 81, the end of the elastic rod 82 enters the second accommodating groove 118 from the first accommodating groove 117, that is, the guide rail installation method is changed to the screw fixing installation method, and the end of the elastic rod 82 enters the first accommodating groove 117 from the second accommodating groove 118, that is, the screw fixing installation method is changed to the guide rail installation method, which is more convenient to adjust.

[0046] like Figure 3 As shown, a plurality of limit bars 112 are arranged on the side wall inside the shell 10, and corresponding limit grooves are arranged on the circuit board 20. When installing the circuit board 20, the limit bars 112 can be inserted into the limit grooves to realize the rapid positioning and fixation of the circuit board 20; and the limit bars 112 arranged in the shell 10 also have the effect of increasing the strength of the shell 10.

[0047] As an embodiment of the present application, various wiring terminals 40 can be classified as needed, and the same type of wiring terminals 40 can be set on the same level (same chamber), and different types of wiring terminals 40 can be set on different levels (different chambers); in the present application, the wiring terminals 40 include RS485 communication interface, RS232 communication interface, CAN communication interface, Ethernet communication interface, HBS communication interface, current analog output interface, voltage analog output interface, dry node output interface and power interface; the RS485 communication interface has four channels, two of which are located on the shell 10 corresponding to the second chamber, and the other two are located on the shell 10 corresponding to the first chamber, and a two-terminal type is used to communicate with the air-conditioning unit or the user's centralized control system; the RS232 communication interface has two channels, both of which are located on the shell 10 corresponding to the second chamber, and a three-terminal type is used to communicate with the air-conditioning unit or the user's centralized control system; the CAN communication interface has two channels, both of which are located on the shell 10 corresponding to the second chamber, and a three-terminal type is used to communicate with the air-conditioning unit or the user's centralized control system; 10, adopts a two-terminal type, which is used to communicate with the air-conditioning unit or the user's centralized control system; the Ethernet communication interface has two ways, both of which are located on the shell 10 corresponding to the first chamber, and adopts RJ45, which is used to communicate with the air-conditioning unit or the user's centralized control system; the HBS communication interface has two ways, both of which are located on the shell 10 corresponding to the first chamber, and adopts a two-terminal type, which is used to communicate with the air-conditioning unit or the user's centralized control system; the current analog output interface has one way, which is located on the shell 10 corresponding to the first chamber, and outputs 4-20mA current; the voltage analog output interface has one way, which is located on the shell 10 corresponding to the first chamber, and outputs 0-10V voltage; the dry node output interface has two ways, both of which are located on the shell 10 corresponding to the second chamber, and adopts a three-terminal type, which can be used in scenarios requiring remote monitoring, automatic control, etc., such as building automatic control systems, smart home systems, industrial automation control systems, etc.; the power supply interface is located on the shell 10 corresponding to the first chamber, and adopts a two-terminal type or a DC round head interface.

[0048] Applying the above-mentioned gateway device to the air-conditioning flexible control system can achieve better control characteristics.

[0049] like Figure 8An air conditioning flexible control system is shown, comprising several air conditioners, at least one multi-interface air conditioning flexible control protocol conversion gateway, and an intelligent measurement terminal; several of the air conditioners are connected to one multi-interface flexible control protocol conversion gateway, and corresponding interfaces can be added by adding multi-interface flexible control protocol conversion gateways to connect more air conditioners, the multi-interface flexible control protocol conversion gateway is connected to the intelligent measurement terminal, and the intelligent measurement terminal communicates with an external system; multiple multi-interface air conditioning flexible control protocol conversion gateways are connected to one intelligent measurement terminal.

[0050] The intelligent measurement terminal receives internal data of the multi-interface air-conditioning flexible control protocol conversion gateway and external data of external power consumption restriction and control, and feeds back the internal data to the external system. At the same time, it receives external data and feeds back the processed data to the multi-interface air-conditioning flexible control protocol gateway. Remote control can be achieved by receiving external data, and localized operation and comprehensive control of air conditioners connected to different multi-interface air-conditioning flexible control protocol conversion gateways can be achieved by receiving internal data.

[0051] The multi-interface air-conditioning flexible control protocol conversion gateway receives and processes the operating parameters of several of the air conditioners, and converts the information obtained by different air conditioners into recognizable general information through an internal protocol conversion module. The general information is internal data, which can be sent to the intelligent measurement terminal. At the same time, it receives external data from the intelligent measurement terminal for processing and sends control signals to each air conditioner for control; before sending the control signal, it is also necessary to convert the control signal into a signal that can be recognized by each air conditioner through a protocol conversion module; the control signal is flexibly adjusted for different air conditioners based on the actual power consumption data and power consumption restrictions.

[0052] Among them, the operating parameters include the unit number, working mode, start and stop status, set temperature, actual temperature, load data, outlet water temperature and return water temperature of the air conditioner, but are not limited to these. Appropriate operating parameters can be selected according to actual control needs.

[0053] The flexible adjustment is to automatically adjust some operating parameters of the air conditioner up or down according to demand to meet the electricity demand of the entire area; for example, during the peak period of electricity consumption, the electricity consumption of a certain area is restricted. At this time, the air conditioners in the area are running at high power and cannot meet the electricity demand of everyone. The air conditioner flexible control system is used to adjust the set temperature of different air conditioners. If the set temperature of the air conditioner is too low, it can be adjusted upward by 3-5°C to meet people's comfortable electricity demand. If it still cannot meet people's comfortable electricity demand, the air conditioner can be shut down to ensure lighting to meet people's basic electricity demand.

[0054] The flexible adjustment strategy may be:

[0055] According to the overall energy consumption of all air conditioners and the power consumption limit of the area, the set temperatures of different air conditioners are automatically adjusted; the set temperatures can be directly obtained by reading the operating parameters of the air conditioners.

[0056] According to the overall energy consumption of all air conditioners and the power consumption limit of the area, the ambient temperature of different air conditioners is automatically adjusted; the ambient temperature here is the room temperature of the air conditioner, and the ambient temperature can be obtained directly by reading the operating parameters of the air conditioner, or by an external temperature sensor, or by calculating the outlet water temperature and return water temperature of the air conditioner.

[0057] According to the operating power of the air conditioner and the power consumption limit of the area, the operating power of different air conditioners is automatically adjusted; the operating power here can be obtained by obtaining the actual current and rated current of the air conditioner, and the ratio between the actual current and the rated current can be obtained by calculation. When the ratio is too small, it means that the power of the air conditioner is wasted and needs to be adjusted.

[0058] In summary, through the design of the gateway structure, the volume becomes smaller and more compact, and different air conditioners can be connected and controlled separately at the same time; the multi-layer design can design interfaces with different functions in layers, thereby reducing the problem of wrong connection of lines and improving construction speed and safety performance; the acquired signals are converted into recognizable universal signals according to the protocols of different air conditioners through the protocol conversion module for analysis and reading; automatic control is performed according to the operating parameters of different air conditioners to reduce unnecessary energy consumption losses in air conditioning operation, thereby significantly improving the efficiency of air conditioning; flexible adjustment can be performed through a local server or a remote workstation to adjust the start and temperature settings of the air conditioner in a timely manner according to actual conditions and needs; through refined adjustment, the air conditioning flexible adjustment system can reduce power loss and achieve energy saving effects.

[0059] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
