[0002] An air conditioning unit is a device that generates cold water through refrigerant (such as R22, etc.) and compressor work to supply the terminal air conditioning box. It is mainly assembled from various air processing functional sections, including air mixing, flow balancing, filtration, cooling, heating, dehumidification, humidification, air supply fan, return air fan, water spray, silencer, heat recovery and other units. The main functions of the air conditioning unit include cooling and dehumidification, air supply and ventilation, and dehumidification and drying, so as to provide users with a comfortable indoor environment.

[0116] In this example, the controller 1 is connected to at least one wiring module 3 so that the controller 1 can be connected to at least one external device 4 through the at least one wiring module 3. By providing the housing 2, it is prevented that foreign debris and oil enter the controller 1 and cause damage to the controller 1.

[0117] The controller 1 can detect the temperature and humidity of the area where the terminal equipment of the air-conditioning unit is located through the external device 4, and control the opening and closing, cooling capacity and heating capacity of the terminal equipment of the air-conditioning unit through the external device 4 according to the temperature and humidity, so as to realize automatic temperature and humidity control of the area where the terminal equipment of the air-conditioning unit is located according to the actual temperature and humidity of the area where the terminal equipment is located. Therefore, it realizes the beneficial effect of reducing the energy consumption of the air-conditioning unit on the basis of dynamic temperature and humidity control of the area where each terminal equipment under the air-conditioning unit is located.

[0118] By setting a display screen 5 to display the connection status between the wiring module 3 and the external device 4, the staff can intuitively confirm the connection status between the controller 1 and the external device 4, thereby ensuring the reliability of the connection management between the controller 1 and the external device 4.

[0119] An indicator light 7 is set to display the connection status between the controller 1 and the master control device 6, so that the staff can intuitively confirm the connection status between the controller 1 and the master control device 6 and the reliability of the connection management between the pillow management controller 1 and the master control device 6.

[0120] In a preferred embodiment, the housing 2 has a vent 21, and the vent 21 connects the interior of the housing 2 with the outside;

[0121] The energy-saving control device further includes: a cooling system 8 , and the cooling system 8 is connected to the controller 1 .

[0122] In this example, the vents 21 are provided to facilitate the heat in the housing 2 to diffuse to the outside, which is beneficial to cooling the controller 1 .

[0123] The cooling system 8 is provided to absorb the heat generated by the controller 1 during operation, thereby ensuring that the controller 1 can operate smoothly.

[0124] In a preferred embodiment, the controller 1 includes: a central processing unit 11, at least one memory bar 12, and at least one mounting board 13;

[0125] The central processing unit 11 is connected to each of the memory bars 12 respectively, and the central processing unit 11 and at least one of the memory bars 12 are fixed inside the housing 2 via a first mounting plate 131; wherein the first mounting plate 131 is one of the at least one mounting plate 13;

[0126] The central processor 11 is connected to at least one of the wiring modules 3 , and one of the wiring modules 3 is connected to one of the mounting plates 13 .

[0127] In this example, a central processing unit 11 is used as the central processing unit 11. The central processing unit 11 (Central Processing Unit, referred to as CPU) is the computing and control core of the computer system and the final execution unit for information processing and program operation. The central processing unit 11 has built-in software function modules of different types and quantities, and has the following basic functions: proportion, proportion + integral, proportion + integral + differential, on / off, time weighting, sequence, arithmetic, logical comparison, counter, etc. For applications with complex control requirements, advanced control algorithms should also be provided. Through flexible configuration, the needs of most intelligent building monitoring can be met. The central processing unit 11 has a built-in embedded operating system based on the Internet of Things, which can greatly improve the real-time and scalability of the operation of the central processing unit 11.

[0128] Memory is also called internal storage. It is used to temporarily store the calculation data in the CPU and the data exchanged with external storage such as hard disk. As long as the computer is running, the CPU will transfer the data to be calculated to the memory for calculation. When the calculation is completed, the CPU will transmit the result. The operation of the memory also determines the stable operation of the computer.

[0129] By providing the mounting plate 13 , the central processing unit 11 and the memory stick 12 can be stably and firmly fixed inside the housing 2 .

[0130] In a preferred embodiment, the cooling system 8 includes: a power system 81, a fan 82 and a water cooling system 83;

[0131] The power system 81 is connected to the fan 82, the power system 81 is fixed on the second mounting plate 132, and the fan 82 is fixed on the upper surface of the second mounting plate 132;

[0132] The power system 81 is connected to the water cooling system 83, and the water cooling system 83 is respectively connected to the lower surface of each mounting plate 13;

[0133] The second mounting plate 132 is one of the at least one mounting plate 13 , and the second mounting plate 132 is different from the first mounting plate 131 .

[0134] In this example, by fixing the power system 81 on the second mounting plate 132, the heat generated by the power system 81 is prevented from being transferred to the controller 1 on the first mounting plate 131, thereby ensuring the stable operation of the controller 1.

[0135] The fan 82 is provided to blow air to the controller 1 so as to reduce the temperature of the controller 1 during operation.

[0136] The water cooling system 83 is provided to absorb the heat generated by the controller 1 so as to reduce the temperature of the controller 1 during operation.

[0137] Therefore, by setting the fan 82 and the water cooling system 83, the cooling efficiency of the cooling system 8 is greatly guaranteed, and the operating reliability of the controller 1 is guaranteed.

[0138] In a preferred embodiment, the power system 81 includes: a motor 811 and a reducer 812; the reducer 812 includes a first input end 8121, a first output end 8122, and a second output end 8123;

[0139] The reducer 812 is connected to the central processor 11;

[0140] The first input terminal 8121 is connected to the motor 811, and the motor 811 is connected to the central processor 11;

[0141] The first output terminal 8122 is connected to the fan 82, and the fan 82 is connected to the central processor 11;

[0142] The second output end 8123 is connected to the water cooling system 83 , and the water cooling system 83 is connected to the central processing unit 11 .

[0143] In this example, the central processor 11 is connected to the reducer 812 to control the gear ratio of the first output terminal 8122 and the second output terminal 8123 of the reducer 812, thereby adjusting the torque and speed received by the fan 82 and the water cooling system 83.

[0144] The fan 82 is connected to the central processor 11 and sends the rotation speed of the fan to the central processor 11 . When the rotation speed of the fan 82 exceeds a preset rotation speed threshold, the central processor 11 will reduce the rotation speed of the fan 82 .

[0145] The water cooling system 83 is connected to the central processing unit 11. The compressor of the water cooling system 83 sends the speed of the compressor to the central processing unit 11. When the speed of the compressor exceeds a preset compression threshold, the central processing unit 11 will reduce the speed of the compressor.

[0146] By providing a reducer 812 having a first input terminal 8121, a first output terminal 8122 and a second output terminal 8123, the technical effect of simultaneously driving the fan 82 and the water cooling system 83 by one motor 811 is achieved, the space occupied by the power system 81 is reduced, and the component composition of the power system 81 is greatly reduced, thereby ensuring the operating reliability of the power system 81.

[0147] It should be noted that a multi-output reducer 812 is used as the reducer 812 of the present application. The multi-output reducer 812 is used to slow down the rotational input speed and transmit the slowed rotational power to different mechanical parts or systems through multiple output shafts. It is usually composed of a series of gears or other transmission elements to achieve the desired reduction ratio, and can have multiple output shafts, and the output speed on each output shaft may be different.

[0148] In a preferred embodiment, the water cooling system 83 includes: a heat absorbing pipe 831, an input pipe 832, a compressor 833, an output pipe 834, a compression pipe 835 and at least one heat sink 836;

[0149] The heat absorption pipe 831 is fixed on the lower surface of the first mounting plate 131;

[0150] The heat absorption pipe 831 is connected to one end of the input pipe 832, and the other end of the input pipe 832 is connected to the compressor 833;

[0151] The compressor 833 is connected to one end of the output pipe 834, the other end of the output pipe 834 is connected to the compression pipe 835, and the compressor 833 is also connected to the central processor 11;

[0152] The compression tube 835 is fixed to the lower surface of the third mounting plate 133, and the third mounting plate 133 is a mounting plate 13 on a side close to the vent 21 of the housing 2 among at least one of the mounting plates 13;

[0153] One end of the heat sink 836 is connected to the compression tube 835, and the other end of the heat sink 836 extends out of the housing 2;

[0154] The heat absorbing tube 831 , the input tube 832 , the output tube 834 and the compression tube 835 contain heat dissipation medium.

[0155] In this example, by setting a heat absorption tube 831, the heat dissipation medium in the heat absorption tube 831 absorbs the heat generated by the controller 1, and by setting an input tube 832, a compressor 833 and an output tube 834, the heat dissipation medium that absorbs heat in the heat absorption tube 831 is output to the compression tube 835; by setting a compression tube 835, the heat dissipation medium releases heat in the compression tube 835, and by setting a heat sink 836, the efficiency of heat release of the compression tube 835 is improved, thereby improving the overall heat dissipation efficiency of the water cooling system 83.

[0156] In a preferred embodiment, one or more of water, inorganic compound refrigerant, Freon, saturated hydrocarbon refrigerant, unsaturated hydrocarbon refrigerant, azeotropic mixture refrigerant and heat transfer oil are used as the heat dissipation medium;

[0157] The diameter of the compression tube 835 is smaller than the diameters of the heat absorption tube 831 , the input tube 832 and the output tube 834 .

[0158] In this example, by making the diameter of the compression tube 835 smaller than the diameters of the heat absorption tube 831, the input tube 832 and the output tube 834, when the compressor 833 presses the heat dissipation medium from the larger-diameter heat absorption tube 831, the input tube 832 and the output tube 834 into the smaller-diameter compression tube 835, the heat dissipation medium in the compression tube 835 will release heat due to compression, and then dissipate the heat to the outside through the compression tube 835 and the heat sink 836, and the heat dissipation medium with a lower temperature will flow back to the heat absorption tube 831, thereby improving the heat dissipation efficiency of the water cooling system 83.

[0159] In a preferred embodiment, at least one of the external devices 4 includes: at least one field sensor, at least one field temperature sensor and at least one switch value;

[0160] At least one of the external devices 4 further comprises: one or more of at least one frequency converter and at least one actuator;

[0161] Wherein, the field sensor is used to detect humidity data of the area where the air conditioning unit terminal device is located;

[0162] The field temperature sensor is used to detect the temperature data of the area where the air conditioning unit terminal device is located;

[0163] The switch quantity is used to control the opening and closing of the terminal equipment of the air-conditioning unit;

[0164] The frequency converter is used to control the cooling capacity and heating capacity of the terminal equipment of the air-conditioning unit;

[0165] The actuator is used to control the cooling capacity and heating capacity of the terminal equipment of the air-conditioning unit.

[0166] In this example, the switch quantity refers to a device used to realize the acquisition and output of discontinuous signals. The switch quantity realizes the discontinuous switch control of the water spray gun based on the acquisition and output of discontinuous signals. The switch quantity refers to the acquisition and output of discontinuous signals, including remote control acquisition and remote control output. It has two states, 1 and 0, which is the nature of the switch in the digital circuit, and in terms of electricity, it refers to the opening and closing of the circuit or the connection and disconnection of the contacts. "Open" and "close" are the most basic and typical functions of electrical appliances. Generally, the switch quantity device realizes the output of the switch quantity through an internal relay. The water spray gun is a device used to spray water on the lawn of a football field. Therefore, the water spray gun output using the switch quantity is, for example, open in the first second, closed in the second second, open in the third second, and so on.

[0167] The variable-frequency drive (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the working power frequency of the motor 811. The variable-frequency drive is used to control the water spraying frequency of the motor 811 of the water spray gun. The variable-frequency drive of the motor 811 is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, microprocessor unit, etc.

[0168] The actuator is a combination of an actuator and a control valve in an automatic control system. The actuator is used to control the amount of water sprayed per unit time by the water spray gun.

[0169] In a preferred embodiment, it further comprises: an indication gateway module 9;

[0170] At least one of the indicator lights 7 is fixed to the indicator gateway module 9;

[0171] The indication gateway module 9 also includes at least one network interface 837;

[0172] The network interface 837 is connected to the controller 1 and is also used to establish a communication connection with at least one terminal device.

[0173] In this example, an indicating gateway module 9 is provided to integrate the indicator light 7 and the network interface 837 into one, so as to facilitate observation of whether a connection is established between the master control device 6 and the controller 1, and also facilitate observation of whether a connection is established between the terminal device and the controller 1, so that the user can obtain the connection status of the communication connection between the controller 1 and the master control device 6, the terminal device and other control devices through an indicating gateway module 9.

[0174] The network interface 837 is an Ethernet interface, which is a physical interface for a computer or other network device to connect to an Ethernet network. Ethernet is a common local area network (LAN) technology that uses a set of standardized protocols to communicate data on a local area network. An Ethernet interface is usually connected to a network via a cable, and an Ethernet cable can be a copper cable (such as a twisted pair) or an optical fiber. Ethernet interfaces usually appear in the form of an Ethernet card, also known as a network interface 837 card (NIC). They are physical devices installed on a computer or other network device, responsible for transmitting data from a computer to a network, and receiving data from a network and transmitting it to a computer. An Ethernet interface usually has one or more ports for connecting a network cable.

[0175] In this embodiment, the indication gateway module 9 includes three indicator lights 7, which are RS485 1 indicator light 7, RS485 2 indicator light 7 and RS485 3 indicator light 7. RS485 1 indicator light 7, RS485 2 indicator light 7 and RS4853 indicator light 7 are respectively used to indicate whether a wiring terminal in the first wiring module 31 connected to the master control device 6 is connected to the master control device 6.

[0176] Optionally, the indicating gateway module 9 also includes: a debugging button 92, a power light 93, an RJ-45 communication light 94 and a network operation light 94.

[0177] Debug button 92 is used to test communication during BACnet IP networking debugging;

[0178] The power light 93 is connected to the controller 1, and is used to indicate whether the controller 1 is powered on;

[0179] RJ-45 communication indicator 94, RJ-45 indicator light 7 is used to indicate whether the controller 1 has achieved BACnet IP networking communication;

[0180] The network operation light 94 is used to indicate whether the BACnet IP controller 1 program is running normally;

[0181] RS485 1 / 2 / 3 communication indicator (red): Flashes when the panel is communicating with RS485 / MODBUS.

[0182] Exemplarily, the connection terminals of at least one connection module 3 include: at least one DI terminal, at least one UI terminal, at least one RS485 terminal; at least one DC terminal, at least one DO terminal and at least one AO ​​terminal.

[0183] It should be noted that the UI terminal is used to receive voltage signals, which include: instantaneous stop signal, pause signal, safe speed signal, cycle stop signal, alarm release signal, external start signal, HOME input signal, enable signal, filter signal and automatic operation start signal.

[0184] The instantaneous stop signal is used to cut off the servo power supply through software. The IMSTP input is always valid and is usually ON. If the signal becomes OFF, the system performs the following processing: 1. Disconnect the servo power supply after issuing an alarm.

[0185] The pause signal is used to issue a pause command from an external device. The HOLD input is always valid and is usually ON. When this signal becomes OFF, the system performs the following processing: 1. Decelerates and stops the action in progress, interrupting the execution of the program. 2. When "Servo during pause" is set to valid in the general settings, an alarm is issued and the servo power is disconnected after the robot stops.

[0186] The safety speed signal is used to stop the robot when the safety fence door is opened. This signal is usually connected to the safety latch of the safety fence door. The SFSPD input is always valid and is usually ON. If the IMSTP, *HOLD, and *SFSPD signals are not used, these signal lines are connected across (normally closed points).

[0187] The cycle stop signal is used to terminate the currently executing program (always valid). Use RSR to release the program in the standby state. If "After CSTOPI input, the program is forced to end" is set to invalid in the system setting screen [6 System Settings, System Settings], the currently executing program will be executed to the end and then terminated. Use RSR to release (clear) the program in the standby state. (Standard setting)

[0188] The alarm release signal is used to release the alarm and is always valid. When the servo power is disconnected, turn on the servo power. At this time, the alarm will not be released before the servo device starts. This signal works when the signal is disconnected under the default setting.

[0189] The external start signal is used for external start. (The falling edge of the signal is valid).

[0190] The HOME input signal is used to return to the home page.

[0191] The enable signal is used as a power-on signal for the robot motor 811 during remote startup.

[0192] The filter signal is used when the PNS selects the program name. When UI

[17] = ON, it allows the PNS1-PNS8 signals to be read and converted into decimal to identify the PNS program name.

[0193] The automatic operation start signal is used to start the currently selected program from the first line. The falling edge of the signal is effective. When used with PNS, the program selected by PNS is executed from the first line. When not used with PNS, the program selected by the teaching operation panel is executed from the first line. When other programs are being executed or paused, this signal is ignored.

[0194] The DI terminal is used to receive DI signals. DI signals are digital input signals. The so-called digital signals are high level 1 and low level 0, which means open or closed in control. DI is an input signal of a switch quantity, giving PLC or DCS an open and close command, just like a normally open start button switch. Pressing it is a closed signal. It is often used for status display. For example, when the circuit breaker is closed, it will be displayed as closed on the DCS screen.

[0195] The DO terminal is used to output DO signals. DO signals are digital output signals, which are output signals of switching quantities. That is, the PLC sends a start or stop signal to the device to start the device. For example, the start of motor 811 is determined by the DCS to send a start command, the control circuit of motor 811 is connected, the contactor is energized and the motor 811 starts. The function is the same as the start button.

[0196] The AI ​​terminal is used to receive AI signals. AI signals are analog inputs. The so-called analog quantity is a 4-20mA or 0-10V current or voltage signal. It is input into the DCS and, after transformation, is restored to its original value. For example, the current value is displayed in the DCS. The secondary value of the current transformer (5A) is converted into a 4-20mA signal (5A corresponds to 20mA) by a current transmitter and input into the DCS cabinet. After conversion, the actual current value is displayed in the DCS.

[0197] The AO terminal is used to output AO signal, which is analog output. AO is a 4-20mA or 0-10V signal output by DCS to control the operating parameters of the equipment. For example, the speed control process of the frequency converter, taking 40HZ as an example, through remote DCS control, it is considered that the given parameter value is: 40HZ, and the DCS also sends a corresponding analog current value within the range of 4-20mA (20mA corresponds to 50HZ). The signal is transmitted to the controller 1 of the frequency converter, and the frequency converter runs at 40HZ as required.

[0198] The RS485 terminal is used to connect computers and maintenance equipment. RS485 is a universal communication standard that is widely used in data acquisition and control applications. One of its main advantages is that it allows multiple RS485 devices to be placed on the same bus, which allows multiple nodes to be connected to each other. It can be used to connect computers and maintenance equipment to achieve data transmission. When installing the RS485 interface, it is necessary to follow the specific wiring terminal 5454 instructions to wire it to ensure that the system can work properly. This article will introduce the detailed instructions of the RS485 wiring terminal 5454 and how to correctly install the RS485 interface.

[0199] The DC24 terminal is used to connect a DC24V external relay.

[0200] Furthermore, the UI terminal is used to connect with a field sensor, a field temperature sensor, a switch, a frequency converter, and an actuator;

[0201] The DI terminal is used to connect to a switch quantity;

[0202] The DO terminal is used to connect to a switch quantity;

[0203] The AO terminal is used to connect with field sensors, frequency converters and actuators;

[0204] The RS485 terminal is used to connect to the master control device 6;

[0205] The DC terminal is used to connect to a power source.

[0222] The Ethernet daisy chain topology is used between controllers 1. The length of the RJ45 Category 6 cable between two communication points should not exceed 100 meters. If it exceeds 100 meters, an Ethernet switch cascade or optical fiber communication should be used instead.

[0223] RS485 data lines must be twisted into pairs. It is strictly forbidden to use star connections and forked connections such as "┳, ╋, *" for wiring. A hand-in-hand bus structure must be used.

[0224] RS485 is used to connect with the master control device 6 through serial communication. Serial communication refers to a communication method in which both parties communicate bit by bit and abide by the timing. In serial communication, data is transmitted bit by bit in sequence, and each bit of data occupies a fixed length of time. In other words, information exchange between systems can be completed using a few communication lines. It is particularly suitable for long-distance communication between computers and computers, and between computers and peripherals. Serial communication is mostly used for serial transmission of data between systems (multi-master control systems), between devices (master control devices and auxiliary devices), and between devices (master control CPU and functional chips) to achieve data transmission and sharing.
