It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a thermostat control system is provided, which includes a thermostat device 110 and a controlled device 120, where the thermostat device 110 and the controlled device 120 are both mounted on a solid medium 200, and the thermostat device 110 communicates with the controlled device 120 by transmitting mechanical waves through the solid medium 200 to control the operation of the controlled device 120. The type of the solid medium 200 is not exclusive, and only mechanical waves need to be propagated. For example, the solid medium 200 may be a building wall, the thermostat device 110 and the controlled device 120 are installed on the building wall, and the mechanical waves are transmitted through the building wall to perform communication, so that an effective communication mode is provided for the devices by using an existing environment, and there is no limitation on an installation location and no modification to the installation environment is required.
In particular, the way that the thermostat device 110 communicates with the controlled device 120 by transmitting mechanical waves through the solid medium 200 is not exclusive, and in one embodiment, the mechanical waves are ultrasonic waves. The communication basis is carried out by using ultrasonic waves, the transmission duration length is used as high and low bits for transmission in a period of time, and the data frame is split into bits according to bytes, so that data transmission between the temperature controller device 110 and the controlled device 120 is realized, and the purpose of controlling the controlled device 120 is achieved. The type of the controlled device 120 is not exclusive, and may be a compressor, a blower device, or the like, and the thermostat device 110 may communicate with the controlled device 120 in the form of ultrasonic waves through the solid medium 200 according to a received control instruction or an acquired ambient temperature, and control the controlled device 120 to achieve temperature adjustment.
The ultrasonic wave is utilized for communication, interference to an electromagnetic field can be avoided, and the problem that regional communication shielding can be caused by reflection and refraction of the ultrasonic wave on a wall surface when communication is carried out through a gas medium is avoided. In addition, the ultrasonic wave is fast in solid transmission and limited in loss range, and the communication efficiency and stability can be ensured by transmitting the ultrasonic wave through the solid medium 200 for communication.
In the temperature controller control system, the temperature controller device 110 communicates with the controlled device 120 by transmitting mechanical waves through the solid medium 200, so that the temperature controller device 110 is used to control the operation of the controlled device 120. Utilize mechanical wave fast at the solid transmission, the little characteristics of loss utilize existing environment to provide effectual communication mode for equipment, as long as equipment fixing just can communicate on same solid medium 200, do not have the restriction of mounted position and need not to reform transform the installation environment, compare with traditional temperature controller product, improved the installation convenience.
Further, also taking mechanical waves as ultrasonic waves as an example, in one embodiment, the thermostat device 110 includes a thermostat and an ultrasonic communication device, the ultrasonic communication device is fixed on the thermostat and is disposed in contact with the solid medium 200; the temperature controller transmits ultrasonic waves to the solid medium 200 through the ultrasonic communication device to communicate with the controlled device 120. Wherein, ultrasonic communication device can include supersonic generator and ultrasonic receiver, and supersonic generator and ultrasonic receiver are fixed in the temperature controller, and all set up with solid medium contact. The temperature controller receives the ultrasonic waves transmitted in the solid medium 200 through the ultrasonic receiver, and transmits the ultrasonic waves to the solid medium 200 through the ultrasonic generator according to the received instruction or the detected ambient temperature so as to be received by other equipment.
In addition, the number of thermostat devices 110 is not unique, and may be only one, or two or more. In one embodiment, the number of the thermostat devices 110 is two or more, and each thermostat device 110 performs ultrasonic communication through the solid medium 200 according to preset identification information. When there are a plurality of thermostat devices 110, each thermostat device 110 stores its own identification information for identification in communication. Each thermostat device 110 may communicate with the controlled device 120 to control the controlled device 120, and the thermostat devices 110 may also communicate with each other. The type of the identification information is also not unique, and may be a device name, a serial number, or the like, and the serial number may be obtained by letters, numbers, or a combination of the two. In this embodiment, the identification information uses an ID (Identity) number.
Specifically, when the thermostat device 110 performs communication, 2 devices may be placed in a location with solid connections for pairing in a secret password control manner during initial configuration. As shown in fig. 2, the thermostat device 110 may include a device a and a device B, which are configured for acoustic communication based on a unified solid medium 200 (specifically, a building wall). The ultrasonic communication means in both apparatus a and apparatus B include an ultrasonic generator T and an ultrasonic receiver R. For the controlled device 120 which is difficult to contact and is used for remaking the lap joint, such as the device X in fig. 2, a fan is assumed, and after an ultrasonic communication device is additionally arranged on the fan, the fan can be connected into the temperature controller control system. The control of the fan can be completed by the device A and can also be completed by the device B. The temperature of the environment is adjusted by controlling the starting and stopping of the fan by the equipment A or the equipment B, so that the temperature is controlled. The equipment A and the equipment B can be placed at will without being limited by the environment as long as the equipment A and the equipment B are provided with ultrasonic communication devices and are connected into the same building wall.
In one embodiment, the thermostat devices 110 located in the same local area network communicate with each other through the solid medium 200 using ultrasonic waves in the same wavelength band. When there are many thermostat devices 110, the thermostat devices 110 that have communication needs may be set as devices in the same local area network, and the thermostat devices 110 in the same local area network communicate using ultrasonic waves in the same band range. By adopting the spectrum partition, different local area networks are isolated by applying different spectrums, thereby reducing the communication interference between the temperature controller devices 110 and improving the communication stability of the temperature controller control system. It should be understood that when there are a plurality of controlled devices 120, the thermostat devices 110 and the controlled devices 120 may be set up in different local area networks, and the ultrasound waves in the same wavelength band may be used for communication between the thermostat devices 110, between the controlled devices 120, and between the thermostat devices 110 and the controlled devices 120 in the same local area network.
In one embodiment, when the thermostat device 110 does not detect that the identification information is stored, the new identification information is stored according to the monitored identification information of the thermostat device 110 in the same local area network. Specifically, when a plurality of thermostat devices 110 exist on the same building wall, if a new thermostat device 110 needs to be added, an operator may set the ultrasonic communication band of the thermostat device 110 to be newly added according to a desired lan. After the operator fixes the thermostat 110 to be newly added to the building wall, the newly added thermostat 110 communicates with other thermostats 110 in the same lan to obtain the ID number of the existing thermostat 110 in the lan. The newly added thermostat device 110 creates a new device ID number by listening on its own to exclude the existing device ID numbers present in the environment. As shown in fig. 3, after the newly added device C monitors the ID numbers of the device a and the device B in the same lan, the ID numbers of the existing devices are excluded and the ID numbers of the devices are newly created for storing their own device ID numbers.
In this embodiment, the thermostat device 110 eliminates the ID number of the existing device existing in the environment by adopting a self-monitoring manner, so as to create a new device ID number, avoid the problem of abnormal communication due to the repeated ID numbers in the communication, and is simple, convenient and fast to operate.
In another embodiment, when the thermostat device 110 detects that there is a thermostat device 110 not storing identification information in the same local area network, the thermostat device 110 not storing identification information is assigned identification information. With continued reference to fig. 3, the device D may be configured to perform a device total management function, and when detecting that the device C newly added in the same lan does not have an ID number, the device D allocates an ID to the device C according to the ID number of the existing device in the lan. The identity and function of the equipment in the same local area are managed by the equipment D, so that the problem of ID number repetition can be better avoided, and the communication reliability of the temperature controller control system is improved.
In addition, in one embodiment, the thermostat control system further includes an isolator disposed on the solid medium 200, as shown in fig. 3, the isolator 130 is used to eliminate the ultrasonic waves outside the band range of the local area network. Specifically, the thermostat device 110 and the controlled device 120 are installed at the same side of the building wall, and the isolator 130 is installed at the other side of the building wall. An isolator 130 can be arranged corresponding to each local area network, sound waves are generated through phase reversal by the aid of the isolators 130, the sound waves in a specific direction are absorbed, and a stable low-interference environment is provided for the temperature controller control system. Specifically, the isolator 130 may include an acoustic wave detector and an acoustic wave generator, wherein the acoustic wave detector detects an acoustic wave outside the local area network band, and generates a plurality of bands in the frequency band by inverting the acoustic wave generator, so as to weaken the acoustic wave outside the local area network band and eliminate the acoustic wave in the opposite direction.
In this embodiment, the isolator 130 is used to perform inverse phase elimination on the ultrasonic waves outside the local area network, so that the influence of the ultrasonic waves in other bands on the communication between the devices in the local area network can be further eliminated, and the communication reliability of the temperature controller control system is improved.
In order to better understand the thermostat control system, the following detailed explanation is made with reference to specific embodiments.

As shown in fig. 2, when the thermostat device 110 is in communication, the initial configuration may be performed by placing 2 devices in a location with a solid connection and then pairing them together in a secret password control manner. For example, device a and device B are based on a unified solid medium, with an acoustic wave communication configuration. For equipment which is difficult to contact and is used for reconstructing a wiring, if the equipment is a fan as equipment D in fig. 2, the fan can be connected into a temperature controller control system after the ultrasonic communication device is additionally arranged on the fan. The control of the fan can be completed by the equipment A or the equipment B.
As shown in fig. 3, when a plurality of devices exist on the same building. The newly added equipment can select self monitoring to eliminate the ID of the existing equipment existing in the environment, so as to newly establish the equipment ID; or the device D manages the identity and function of the devices in the same local area. Meanwhile, when the number of the devices in the building is large, different device local areas can be distinguished in a band allocation mode, and therefore different device groups are established. When the device population is large, noise interference is caused to the solid-state communication environment. At this time, the sound wave is generated by the isolator 130 in a reverse phase, and the sound wave in a specific direction is absorbed, so as to provide a stable and low-interference environment for the thermostat control system.
