Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be noted that the terms "first," "second," "third," and the like in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

For the purpose of facilitating an understanding of the present application, the technical solutions provided in the present application will be described in detail below with reference to specific embodiments. In the present invention, the technical features of the embodiments and the embodiments may be combined with each other without conflict.

Referring to fig. 1, the utility model provides a temperature controller 1, temperature controller 1 include temperature measurement input port 12, accuse temperature output port 13 and temperature detection memory device 11, and wherein temperature detection memory device 11 records historical temperature measurement data and/or historical accuse temperature data. Thus, the temperature detection memory function is realized through the temperature detection memory device 11, and the overhaul operating personnel can check the operating temperature change condition conveniently to investigate and obtain evidence.

As a preferred embodiment, the temperature detection memory device 11 is detachably connected with respect to the thermostat 1; when detached from the thermostat 1, it can be connected to other temperature control devices. By way of example and not limitation, the temperature sensing memory device 11 may employ a storage mechanism (e.g., solid state flash memory) having a standardized interface (e.g., USB-A, USB-C, etc.). For example, sometimes, since the environment where the temperature detection memory device 11 is located is not convenient for viewing the historical data on site (for example, the temperature on site is high or the space is narrow), the temperature detection memory device 11 can be taken down from the thermostat 1 to other places in a detachable manner and viewed through other temperature control devices. Or, when the storage capacity of the temperature detection memory device 11 itself is hard to meet the current temperature recording requirement, the temperature detection memory device 11 with larger capacity can be conveniently replaced without replacing the whole thermostat 1. Or, because the temperature detection memory device 11 is easy to break down due to long-term operation under the working condition environments of high and low temperature, humidity and the like, the detachable design can improve the maintenance and replacement efficiency of the temperature detection memory device 11.

Further preferably, the other temperature control devices are the same type of temperature control devices as the temperature controller 1. For example, in some thermostat 1, a failure may occur in a component other than the temperature detection memory device 11, and the thermostat 1 may not operate. The universal design can be disassembled between the temperature controller devices of the same type through the temperature detection memory device 11, a fault temperature controller can be replaced by a new temperature controller, and the temperature detection memory device 11 of the fault temperature controller can be disassembled and installed on the new temperature controller, so that the continuity of the working and recording of the temperature controller at the position can be ensured.

As a preferred embodiment, the temperature detection memory device 11 is detachably connected with respect to the thermostat 1; when detached from the thermostat 1, it can be connected to a non-thermostat device. The non-temperature control device can be typically exemplified by a computer device (such as a PC computer or a processor of an ambient temperature on-line monitoring system) for calculating and processing data. For example, the system needs to perform deep and complex calculation processing based on recorded historical temperature measurement data and/or historical temperature control data, and a calculation or processing chip built in the temperature controller is difficult to meet the calculation processing requirement, so that the temperature detection memory device 11 compatible with the temperature controller and non-temperature control equipment such as a PC computer can be detached from the temperature controller, so that the non-temperature control equipment can realize the deep and complex calculation processing.

Preferably, the temperature controller 1 further includes a self-tuning device 15 to calculate a rising and/or falling speed of the measured temperature inputted from the temperature measurement input port 12. In this way, compared with a single measured temperature value in the prior art, the self-tuning device 15 can measure the rise rate of the heat value and/or the heat dissipation rate of the device under test (such as a rectifier element), thereby realizing accurate temperature detection of the device under test.

In the above embodiment, the thermometric input port 12 may be connected to the thermometric device 3 through the thermometric lead 121, and the thermometric device 3 includes a thermal resistor and/or a thermocouple. Preferably, a temperature measuring point can be arranged at each position of the device to be measured (such as each rectifying element), for example, a thermocouple or a thermal resistor is mounted on the device to be measured, so as to improve the comprehensiveness and accuracy of the detection of the ambient temperature.

In the above embodiment, the temperature-controlled output port 13 may be connected to the temperature-controlled response device 4 through the temperature-controlled lead 131, and the temperature-controlled response device 4 includes a relay.

In the above embodiment, the temperature controller 1 further includes an overtaking alarm output port 14, the overtaking alarm output port 14 is connected to the alarm device 5 through an alarm lead 141, and the alarm device 5 includes an alarm lamp. Thus, make the temperature controller possess the warning function of temperature line crossing, when the detection temperature is higher than line crossing temperature (a preset temperature value), accessible warning lead 141 triggers long-range (like the outside red light warning of temperature controller detection room), the suggestion operating personnel notice with key tour.

Referring to fig. 2, the utility model also provides an ambient temperature on-line monitoring system 2, ambient temperature on-line monitoring system 2 includes foretell temperature controller 1. Therefore, the online environment temperature operation monitoring can be conveniently realized through the online environment temperature monitoring system connected with the temperature controller.

Further, the ambient temperature on-line monitoring system 2 further includes a display 21, and the display 21 is connected with the temperature controller 1 to display the current temperature measurement data and/or the set temperature data corresponding to the temperature controller 1.
