Description

Technical Field

[0001] This utility model belongs to the field of electronic control technology, and specifically relates to a temperature range limiting switch system. Background Technology

[0002] In public places such as factories, schools, and office buildings, when using cooling or heating equipment, managers often forget to turn it off due to prolonged use. When the equipment is not in use, people may unintentionally turn it on again, resulting in wasted electricity and potential safety hazards. Furthermore, current temperature switches can only control one temperature point, and the current passing through their main contacts is relatively small. Utility Model Content

[0003] In view of the above-mentioned problems, this utility model provides a temperature range limiting switch system, which enables air conditioning equipment to be turned on within a set temperature range and turned off outside the set temperature range, thereby achieving energy saving.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A temperature range limiting switch system includes a temperature switch, a manual switch, and multiple temperature sensors installed indoors and outdoors. One input terminal of the temperature switch is connected to an AC power input terminal, and the other input terminal is connected to the indoor and outdoor temperature sensors via an RS485 serial bus. One output terminal of the temperature switch is connected to one end of the manual switch via the power cord of an air conditioning unit, and the other end of the manual switch is connected to the power input terminal of the air conditioning unit.

[0006] In one possible implementation, the temperature switch includes a phase wire input port, a phase wire output port, a neutral wire connection port, an RS485 communication interface, a phase wire sampling port, an internal communication bus port, an internal relay status indicator, an RS485 signal indicator, and a manual operation button. The phase wire input port and phase wire output port are used for live wire input and live wire output, respectively. The phase wire input port is fixed to the input live wire by an input port locking screw, and the phase wire output port is fixed to the output live wire by an output port locking screw. The neutral wire connection port is used to connect to the neutral wire. The RS485 communication interface is used to connect to an RS485 serial bus, and the working status of the RS485 communication interface is indicated by an RS485 signal indicator. The internal communication bus port is used to communicate with the host. The internal relay status indicator is used to indicate the WIFI communication status with the host. The manual operation button is used to manually switch the on / off state of the temperature switch.

[0007] The present invention offers the following advantages: it allows for the measurement of multiple ambient temperatures, which can be used as a criterion for determining whether a switch can be turned on, thereby achieving energy savings. For example, in summer, the air conditioner can only be turned on when both indoor and outdoor temperatures exceed the human body's tolerance level. If the outdoor temperature does not exceed the human body's tolerance level, the switch cannot be turned on; instead, the ventilation system is activated to exchange indoor and outdoor temperatures.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0011] See Figure 1 The diagram shows a schematic of a temperature range limiting switch system according to an embodiment of the present invention. It includes a temperature switch, a manual switch, and multiple temperature sensors installed indoors and multiple temperature sensors installed outdoors. One input terminal of the temperature switch is connected to an AC power input terminal, and the other input terminal is connected to the indoor and outdoor temperature sensors via an RS485 serial bus. One output terminal of the temperature switch is connected to one end of the manual switch via the power cord of the air conditioning equipment, and the other end of the manual switch is connected to the power input terminal of the air conditioning equipment.

[0012] See also Figure 2In a specific application example of a temperature range limiting switch system, the temperature switch further includes a phase wire input port 1, a phase wire output port 3, a neutral wire connection port 5, an RS485 communication interface 6, a phase wire sampling port 7, an internal communication bus port 8, an internal relay status indicator 9, an RS485 signal indicator 10, and a manual operation button 11. The phase wire input port 1 and phase wire output port 3 are used for live wire input and output, respectively. The phase wire input port 1 is fixed to the input live wire via an input port locking screw 2, and the phase wire output port 3 is fixed to the output live wire via an output port locking screw 4. The neutral wire connection port 5 is used to connect to the neutral wire. The RS485 communication interface 6 is used to connect to an RS485 serial bus, and its operating status is indicated by the RS485 signal indicator 10. The internal communication bus port 8 is used to communicate with the host computer. The internal relay status indicator 9 indicates the WIFI communication status with the host computer. The manual operation button 11 is used to manually switch the on / off state of the temperature switch.

[0013] The temperature range limiting switch system described above uses two or more external temperature sensors to detect indoor and outdoor temperatures. These sensors employ an RS485 communication interface. The temperature switch reads data from the indoor and outdoor temperature sensors, processes the data, and filters out fluctuating and invalid data. It then determines whether the data meets the activation requirements. If the data meets the requirements, it waits for a certain period (e.g., 5 minutes, the waiting time is configurable). If all data within the waiting time meets the activation requirements, the temperature switch turns on to power the device. Otherwise, the waiting time is reset. The same logic applies to turning off the temperature switch. Specifically, the switch can only be turned on when both indoor and outdoor temperatures exceed the human body's tolerance temperature. The switch cannot be turned on if the indoor temperature exceeds the human body's tolerance temperature but the outdoor temperature does not. The temperature switch can connect to the main unit (energy-saving control system) via WiFi for intelligent temperature control.

[0014] It should be understood that the exemplary embodiments described herein are illustrative and not restrictive. Although one or more embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art will understand that various changes in form and detail may be made without departing from the spirit and scope of the present invention as defined by the appended claims.
