Detailed Description
The present application will be described in further detail with reference to the drawings and examples.
The number of devices in the central air conditioning system is large and the variety is complicated, which puts a great strain on the management of the central air conditioning system. For example, as shown in fig. 1, the central air conditioning system of the water-cooled water machine includes a cooling tower, a central air conditioning host, a water collector, a chilled water pump, and other devices, where the central air conditioning host includes a water-cooled chiller set for providing a cold source and a heat source, and also includes a control device for controlling the operation of the entire central air conditioning system; after the water-cooled water chilling unit refrigerates or heats the heat medium water, the heat medium water reaches a fan coil (namely terminal equipment) through a circulating pipeline, and heat energy or cold energy in the fan coil is sent to a designated position by fresh air or mixed air; when a central air conditioning system of a water-cooled water machine is managed, control equipment needs to control the operation of executing equipment such as a water-cooled water chilling unit and a chilled water pump, the operation state of the executing equipment needs to be monitored, and meanwhile, the energy condition consumed by a fan coil needs to be detected.
In order to solve the above problems, in the related art, a central air conditioning system is generally managed by combining an upper computer and a worker. Specifically, an upper computer can be adopted to monitor the running state of the equipment, and the equipment fault is positioned in a manual inspection mode. Firstly, fig. 2 is a schematic configuration diagram of a central air-conditioning management system in the related art, and as shown in fig. 2, when an upper computer 203 is used for management, on one hand, a control device 201 of the central air-conditioning system is connected with a central air-conditioning main board 205, obtains execution device operation state information collected by the central air-conditioning main board 205, such as an opening state of a central air-conditioning main unit, opening states of a water return switch and a water outlet switch, water temperatures of water return and water outlet, and the like, and sends received data to the upper computer 203 after being processed by a level converter 202 through an RS485 interface; after receiving the data sent by the control equipment, the upper computer 203 can perform processing such as presentation on the received data, thereby realizing monitoring on the running state of the central air-conditioning system; on the other hand, the operating parameters of the central air conditioning system, such as the operating mode of the central air conditioning host (e.g., a cooling mode, a heating mode, a dehumidification mode, a ventilation mode, etc.), the wind speed at the fan coil position, etc., may be configured on the liquid crystal control panel 204 in a manual configuration manner, and the control device 201 may receive control information configured through the liquid crystal control panel 204 through the drive-by-wire interface, or receive control information issued by the upper computer 203 through the drive-by-wire interface, and issue the received control information to each execution device, so as to control the operation of the execution device.
Secondly, when manual management is adopted, each device in the central air-conditioning system can be checked in a regular patrol manner, for example, the water-cooled water machine central air-conditioning system shown in fig. 1 can be manually managed according to the following operation procedures:
checking whether a water-cooling water chilling unit, a cooling tower and a water pump power supply are normal and safely transmitting power;
secondly, starting a cooling tower, a cooling water pump, a freezing water pump and an automatic water replenishing device;
starting a starting switch of the water-cooling water chilling unit, operating an oil pump of a compressor in the water-cooling water chilling unit, enabling the oil temperature to reach 30 ℃, starting the unit in a star angle mode according to a set program and normally operating the unit, observing whether the reading of an oil pressure gauge is in a normal range or not according to a normal operation parameter set value, and observing whether the reading of an air suction pressure gauge and an air exhaust pressure gauge is in a normal range or not; for example, the normal operating parameters are set to: high pressure (exhaust) set point: 1.57MPa, normal operating condition: 1.1MPa to 1.5MPa, exhaust temperature: 45-90 ℃, oil supply temperature: 30 ℃ to 55 ℃, low pressure (suction) setpoint: 0.3MPa, oil pressure: the exhaust pressure + N, the value range of N is 0.2 MPa-0.3 MPa, and the pressure difference set value of the essential oil filter is as follows: 0.1 MPa;
recording operation parameters every two hours in the normal operation process of the water-cooling water chilling unit;
fifthly, leak detection inspection is carried out on the water-cooling water chilling unit once every day, when the leakage condition is found, timely treatment is carried out, if the leakage condition cannot be timely treated, a liquid supply ball valve, an air suction stop valve and an exhaust stop valve of the compressor are immediately closed, and a person in charge is informed;
sixthly, when the water-cooling water chilling unit breaks down, taking measures to process in time;
and seventhly, when the central air conditioning system is closed, stopping the water cooling water chilling unit, and stopping the refrigeration water pump, the cooling tower and other auxiliary equipment after the oil pump motor stops running.
However, when the upper computer is used for management, each central air-conditioning system is often managed individually, and in practical applications, the number of deployed central air-conditioning systems is determined according to the load capacity of the central air-conditioning system, for example, when the central air-conditioning system is applied to an office building, one central air-conditioning system may load the cooling demand of one building, or may load the cooling demand of only several floors, that is, one application site may need to deploy multiple central air-conditioning systems. In this case, it is necessary to perform centralized management of the central air conditioners in the same application site. Meanwhile, manual inspection consumes manpower, is low in efficiency, and can cause problems of missed inspection, wrong inspection and the like, and the problem is more obvious under the condition that a plurality of central air-conditioning systems exist.
Based on this, in various embodiments of the application, the internet of things platform is used for receiving first information sent by at least one central air-conditioning system, and the at least one central air-conditioning system is managed according to the first information, so that centralized management of the central air-conditioning system is realized; meanwhile, equipment faults in the central air-conditioning system are located through the Internet of things platform, manual inspection is not needed, and therefore management efficiency is improved, and accuracy of fault location is improved.
The embodiment of the application provides a central air-conditioning system management method, which is applied to an internet of things platform, and as shown in fig. 3, the method comprises the following steps:
step 301: receiving first information reported by control equipment in at least one central air-conditioning system; the first information comprises second information and/or third information, the second information represents the operation state related information of the control equipment and the at least one execution equipment in the central air-conditioning system, and the third information represents the energy information consumed by the at least one end equipment in the central air-conditioning system;
step 302: for each of the at least one central air conditioning system, based on the corresponding first information, at least one of:
controlling the operation of the control device and the at least one execution device;
fault locating at least one execution device;
the energy consumed by the at least one end device is billed.
In practical application, the control equipment and the platform of the Internet of things can communicate through LoRaWAN.
Based on this, in one embodiment, the LoRaWAN is based on communicating with the control device of the at least one central air conditioning system.
In practical application, when the control device does not have the LorRaWAN communication capacity, the Data of the control device is accessed to the Internet of things platform in a LoRaWAN communication mode, and LoRaWAN virtualization of the control device can be solved by using a LoRaWAN Data Transmission Unit (DTU).
In practical application, the operation of the device can be specifically embodied in two aspects of monitoring and controlling.
Based on this, in an embodiment, the controlling the operation of the control device and the at least one execution device includes at least one of:
acquiring the running state related information of the control equipment and at least one execution equipment from the received first information, and presenting the running state related information;
and/or issuing a control instruction to at least one control device, so that the control device executes the control instruction and then controls the operation of at least one execution device.
In practical application, the control equipment comprises a sending interface used for sending data to the Internet of things platform and a receiving interface used for receiving the data sent by the Internet of things platform; data sent by the sending interface can be accessed to the internet of things platform through the DTU, for example, running state information of the execution equipment; the receiving interface may receive data sent by the internet of things platform through the DTU, for example, a control instruction sent by the internet of things platform to the control device. The DTU may communicate with the internet of things platform based on communication protocols such as a LoRaWAN protocol and a fourth generation mobile communication technology (4G) communication protocol, and a specifically-adopted communication protocol type may be selected from protocols supported by the DTU device according to a use requirement, which is not limited in the embodiment of the present application.
In practical application, the receiving interface of the control device for receiving data may also receive data sent by the internet of things platform without the DTU, and at this time, the control device may receive a control instruction sent by the internet of things platform through the wireless temperature controller; the control device may be connected to the wireless thermostat via a drive-by-wire interface, where the drive-by-wire interface is the receiving interface, and the wireless thermostat communicates with at least one execution device via the drive-by-wire interface. When the Internet of things platform is not required to control the central air conditioning system, the wireless temperature controller can be used for locally managing the central air conditioning system. Specifically, a field engineer may directly configure an operation parameter of the central air conditioning system through the wireless temperature controller, for example, set an operation mode to be cooling or heating, set a cooling temperature, set an air speed, and the like, and the wireless temperature controller generates a control instruction for at least one execution device according to the configured operation parameter, and issues the control instruction to a corresponding execution device through a drive-by-wire interface of the control device to control the operation of the corresponding execution device; when the central air-conditioning system needs to be controlled by the internet of things platform, the wireless temperature controller receives a control instruction sent by the internet of things platform, for example, an instruction for regularly turning on or off a central air-conditioning host, an instruction for controlling an operation mode, and the like, and the wireless temperature controller distributes the received control instruction to corresponding execution equipment through a wire control interface of the control equipment.
In practical application, the protocol type used when the Wireless thermostat communicates with the internet of things platform may be determined according to the Wireless thermostat and a Wireless communication protocol supported by the internet of things platform, for example, if the Wireless thermostat supports a LoRaWAN protocol, the Wireless thermostat may communicate with the internet of things platform based on the LoRaWAN protocol, if the Wireless thermostat supports a Wireless FIdelity (WiFi) protocol, the Wireless thermostat may communicate with the internet of things platform based on the WiFi protocol, and if the Wireless thermostat supports both the LoRaWAN protocol and the WiFi protocol, the Wireless thermostat may be selected according to a specific requirement, which is not limited in this embodiment of the present application.
Here, in practical applications, the control device and the wireless thermostat may be disposed together with a unit for providing a heat source or a cold source in the central air-conditioning host, for example, may be disposed together with a water-cooling chiller in the central air-conditioning system of a water-cooling type water machine, specifically, the control device may be a control device provided in the central air-conditioning host, and the wireless thermostat may be a control panel provided in the central air-conditioning system.
In practical application, in order to enable workers to know fault information in time, a fault positioning result can be presented.
Based on this, in an embodiment, the fault locating at least one execution device includes:
acquiring the running state related information of at least one execution device from the received first information;
based on the acquired relevant information of the running state, fault positioning is carried out on at least one execution device to obtain a fault positioning result;
presenting the results of the fault localization.
It should be noted that the located fault may be a fault of the device itself, or a fault of the running state of the device, for example, for a water flow switch in a circulation pipeline, if it is detected that the on state of the water flow switch does not conform to the currently set mode, it is considered that the water flow switch has a running fault, and if after an on or off instruction is issued to the water flow switch, the water flow switch does not execute the corresponding instruction, it is considered that the water flow switch itself has a fault.
Here, in actual application, the fault location result may be presented in a form of a pop-up window or the like, for example, when the fault location result is not obtained, a display interface of the platform of the internet of things only displays the relevant information of the operating state; when a fault positioning result is obtained, a popup window can be displayed on a display interface of the platform of the Internet of things, and fault content is presented in the popup window to prompt a worker to timely overhaul fault equipment; in actual application, the fault positioning result can be stored for subsequent query. The result of the fault location may include information of the faulty device, such as a name of the faulty device, a location of the faulty device, and the like, and may also include specific content of the fault, such as a fault type, a fault occurrence event, and the like.
In an embodiment, the performing fault location on at least one execution device based on the obtained relevant information of the operating status includes:
judging whether the running state related information meets a preset condition or not aiming at each execution device in at least one execution device to obtain a judgment result;

The central air-conditioning mainboard 405 and the wireless thermostat 404 can communicate with the control device 401 through different interfaces; specifically, the central air-conditioning motherboard 405 communicates with the control device 401 through a motherboard interface of the control device 401, and the wireless temperature controller 404 communicates with the control device through a drive-by-wire interface of the control device 401; wherein the drive-by-wire interface is capable of communicating with an execution device in the central air conditioner.
The DTU device 402 is configured to implement LoRaWAN of the control device 401, that is, data of the control device 401 may access the internet of things platform 403 through the DTU device 402.

Specifically, first, the internet of things platform 403 may receive the operation state related information (i.e., the second information) of the control device 401 itself and the execution device, which is sent by the control device 401, and present the operation state related information on a display interface.
Secondly, the internet of things platform 403 may perform fault location on each execution device in the central air conditioner according to the received running state related information, and after obtaining a fault location result, present the fault location result on a display interface.
Through the state related information and the fault positioning result displayed on the display interface by the internet of things platform 403, engineers can visually check the operation state of the central air conditioning system, and can timely receive the fault positioning result, thereby ensuring the real-time performance of the fault positioning result transmission.
For example, fig. 5 is a schematic view of a display interface of an internet of things platform in a central air-conditioning management system of an application example of the present application, as shown in fig. 5, the information related to the operation state may include information such as the on-off state of hosts of different models, the host name, the host number, the setting state of the host on/off at regular time, and the remaining flow rate, where the remaining flow rate may be a cooling flow rate or a heating flow rate currently provided by the host; when the fault positioning result is presented, a reminding message can be presented on a display interface in a pop-up window mode to achieve the purpose of reminding early warning, and the specific content of the fault positioning result can be checked through a query interface; fig. 6 is a schematic diagram of a first query interface of an internet of things platform in a central air-conditioning management system according to an application example of the present application, and as shown in fig. 6, a fault location result may include information such as a serial number of a fault device, an early warning reason, and an early warning occurrence time.

Fourthly, the internet of things platform 403 may charge the energy used by the user according to the received information related to the energy used by the user; specifically, a corresponding charging policy may be called from a database of the internet of things platform 403, a corresponding charging result may be obtained according to the obtained flow information and the corresponding charging policy, and the charging result may be presented on an inquiry interface, for example, the charging result may be presented on a second inquiry interface shown in fig. 7.
It should be noted that the charging policy used during charging may be a charging policy directly configured on the platform of the internet of things, or a charging policy negotiated with the user; when a charging strategy is directly configured on the platform of the internet of things, charging can be directly carried out according to energy used by terminal equipment, illustratively, the specified charging strategy is unit price of the hot water flowing through the fan coil, and after the flow of the hot water passing through the fan coil is obtained, charging is directly carried out according to the flow and the unit price; when the charging strategy negotiated with the user is used, at least one charging strategy can be provided for the user, and charging is carried out according to the charging strategy selected by the user; for example, at least one recharging package option is sent to the mobile terminal associated with the terminal device, a recharging package represents a charging policy, a corresponding relation between the user and the charging policy is established according to the recharging package option selected by the user, and after the flow of the hot media water passing through the fan coil is obtained, charging is performed according to the flow and the corresponding charging policy. Wherein, under the condition that the platform 403 of the internet of things negotiates a charging policy together with the user, the platform 403 of the internet of things can also store and present the negotiated charging policy; for example, fig. 9 is a schematic diagram of a fourth query interface of an internet of things platform in the central air-conditioning management system of the application example of the present application, as shown in fig. 9, the internet of things platform 403 may present charging policy related information corresponding to the mobile terminal, where the charging policy related information corresponding to the mobile terminal may include user information (e.g., a client number and an equipment-bound room number) corresponding to the mobile terminal, an end device number, a recharge amount (e.g., an amount due and an amount of real payment), and the like; fig. 10 is a schematic diagram of a fifth query interface of the internet of things platform in the central air-conditioning management system according to the application example of the present application, and as shown in fig. 10, the internet of things platform 403 may present a record of sending a charging policy to the mobile terminal, for example: offer name, time of the activity, offer rules, etc.
In practical application, the internet of things platform 403 may also send announcement information to the mobile terminal, so as to instruct the user to perform relevant operations on the terminal device, for example, winter prompt information may be sent to the mobile terminal, and the user may adjust the turn-on state, the air supply temperature, and the like of the terminal device according to the received winter prompt information.
Fifthly, the internet of things platform 403 may send a control instruction to the wireless thermostat 404, so that the wireless thermostat 404 distributes the control instruction to the corresponding execution device through the drive-by-wire interface, thereby realizing the control of the internet of things platform 403 on the execution device in the central air conditioning system; for example, the control of the opening or closing of a valve in a heat medium water circulation pipeline, the control of the rotating speed of a compressor in a unit of a central air-conditioning main unit, the control of the opening and closing of a water flow switch of end equipment and the like. Fig. 11 is a schematic diagram of an internet of things platform configuration interface in a central air-conditioning management system according to an application example of the present application, and as shown in fig. 11, an internet of things platform 403 may present configuration function items for the central air-conditioning system and generate a control instruction based on an operation for the configuration function items.
In practical application, the configuration interface of the internet of things platform 403 may be a separate interface as shown in fig. 11, or may be displayed on a page together with the display interface shown in fig. 5; specifically, one page may be divided into three display areas, where the first display area is used to present the running state related information, the second display area is used to display the fault location result, and the third display area is used to display the configuration function item.
The wireless thermostat 404, which may also be referred to as a wireless control panel, is used to send control information to the control device 401, so that the control device 401 can control the operation of the execution device according to the control information. Here, the control information may be sent to the wireless thermostat 404 by the internet of things platform 403, or may be directly configured by the wireless thermostat 404; specifically, when the central air conditioning system needs centralized management, the wireless temperature controller 404 may receive the control information sent by the internet of things platform 403 and distribute the received control information to corresponding execution devices in the central air conditioning system, when the central air conditioning system does not need centralized management, a field engineer may directly configure the operating parameters of the central air conditioning system through the wireless temperature controller 404, and the wireless temperature controller 404 generates the control information and distributes the control information to the corresponding execution devices in the central air conditioning system, that is, performs local management on the central air conditioning system.
Wherein, in the process of sending control information through the internet of things platform 403, the wireless temperature controller 404 is used for converting a communication protocol; specifically, an RS485 interface of the wired device generally adopts a Modbus communication protocol, and after the internet of things platform 403 sends control information to the wireless thermostat 404 through communication protocols such as LoRaWAN, the wireless thermostat 404 transmits the control information to the drive-by-wire interface of the control device 401 through the Modbus protocol.
Illustratively, if a LoRa thermostat (i.e., a thermostat supporting LoRaWAN protocol) is used, the LoRa thermostat converts the protocol of the transmission control information from LoRaWAN protocol to Modbus protocol supported by RS485 interface; if a Narrow-Band Internet of Things (NB-IoT) thermostat (i.e. a thermostat supporting the NB protocol) is used, the NB-IoT thermostat converts the protocol of the transmission control information from the NB protocol to a Modbus protocol supported by an RS485 interface.
According to the scheme provided by the application example, the central air-conditioning system is managed through the Internet of things platform, centralized management of the central air-conditioning system is achieved, manual inspection is not needed, and the problems of low accuracy and low efficiency caused by manual inspection are solved, so that the management efficiency and the fault positioning accuracy are improved; by using the wireless temperature controller, the central air-conditioning system can be locally managed when centralized management is not needed.
