Description

Technical Field

[0001] This utility model relates to the field of temperature control, specifically to a six-channel fully isolated temperature control device. Background Technology

[0002] In modern industrial production, many production processes require maintaining a certain temperature. Therefore, the most widely used physical quantity controller is the temperature controller. The process of using a temperature controller involves first measuring the temperature, and then adjusting the temperature based on the measurement results to maintain temperature stability.

[0003] However, temperature measurement is mostly electrical, which is greatly affected by the working environment. It is often affected by electromagnetic radiation and electromagnetic induction, resulting in inaccurate temperature measurement results and thus making it impossible to achieve accurate temperature control. To avoid such effects, temperature controllers used in industrial production are often one-to-one controllers. Although this can avoid electromagnetic interference between multiple temperature controllers, it greatly increases the cost. Although multi-channel temperature controllers exist on the market, these products can only be used in environments with good electromagnetic conditions and cannot adapt to complex environments with electromagnetic interference. Therefore, there is an urgent need for a six-channel fully isolated temperature control device that can overcome the above defects. Utility Model Content

[0006] The temperature acquisition module is equipped with six temperature sensors, which are used to collect temperature data.

[0007] The isolation transmission module includes six optically isolated transmission channels, each corresponding to one of the six temperature sensors. These channels are used to acquire temperature data collected by the six temperature sensors and send the temperature data to the load heating module.

[0009] In another embodiment, the load heating module includes a main control unit and a heating unit;

[0010] The heating unit includes six heating loads;

[0011] The main control unit is used to generate six control signals based on the temperature data from six temperature sensors, and to control six heating loads to perform heating based on the six control signals.

[0024] Please see Figure 1 , Figure 1This is a schematic diagram of a six-channel fully isolated temperature control device. The device includes: a temperature acquisition module, an isolation transmission module, and a load heating module. The temperature acquisition module is equipped with six temperature sensors for acquiring temperature data. The isolation transmission module includes six optocoupler-isolated transmission channels, each corresponding one-to-one with one of the six temperature sensors. These channels acquire the temperature data collected by the six sensors and transmit it to the load heating module. The load heating module then heats the device based on the temperature data.

[0025] Optionally, the load heating module includes a main control unit and a heating unit; the heating unit includes six heating loads; the main control unit is used to generate six control signals based on the temperature data from the six temperature sensors, and to control the six heating loads to perform heating based on the six control signals.

[0028] For example, see Figure 2 , Figure 2 The circuit diagram shows a six-channel fully isolated temperature control device. Taking the temperature acquisition and control process as an example, the six-channel fully isolated temperature control device is explained. When temperature control is required, the power supply module first supplies power to the entire six-channel fully isolated temperature control device. Then, six temperature sensors acquire six sets of temperature data, which are transmitted to the main control unit through six optocoupler isolation transmission channels in the isolation transmission module. The main control unit generates six control signals based on these six sets of temperature data, and then transmits these six control signals to six heating loads through the six optocoupler isolation transmission channels in the isolation transmission unit, respectively. The heating loads then heat according to the control signals to achieve temperature control.

The temperature acquisition module is equipped with six temperature sensors for acquiring temperature data. The isolation transmission module includes six optically isolated transmission channels, each corresponding one-to-one with one of the six temperature sensors. These channels acquire the temperature data collected by the six sensors and transmit it to the load heating module. The load heating module then heats the device based on the temperature data. Because six optically isolated transmission channels are provided, isolated transmission of the temperature data acquired by the six temperature sensors is achieved. This not only enables simultaneous multi-point temperature acquisition and control but also achieves separated data transmission, thus improving the accuracy of temperature control while maintaining efficiency.
