Detailed Description
Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.
Prior to proceeding with the description of the embodiments of the present utility model, description will be made of the prior art and the problems that exist therein:
the structure of the existing thermal conductivity detection circuit can refer to fig. 1, as shown in fig. 1, and the existing thermal conductivity detection circuit comprises a dry battery, an MCU, an amplifying circuit, a thermocouple, a probe, a PTC, a regulated power supply, a power supply indicator, a lamp-adjusting potentiometer and a preheating indicator. The process of thermal conductivity detection is described in connection with fig. 1:
first, the power supply of the thermal conductivity detection circuit is a 9V dry cell. After the power switch K is turned on, the amplifying circuit, the LED indicator lamp and the thermistor PTC supply power, and the preheating indicator lamp LED2 is turned on. In addition, the total power supply obtains a +5V power supply through a stabilized voltage power supply to supply power for the MCU. When the switch K is closed, PTC starts to heat, the machine is used for processing a preheating state, the LED2 indicator lamp is on, after the preheating is finished, the temperature of the probe can be kept at a relative constant temperature due to the function of the PTC, the electromotive force at the two ends of the thermocouple is a fixed value, after the probe contacts with diamond during detection, heat on the probe is quickly lost, the electromotive force at the two ends of the thermocouple is changed, the electric signal change is sent to the MCU through the amplifying circuit, so that the thermal conductivity of an object to be measured is judged, the MCU is used for processing to obtain a thermal conductivity detection result, the thermal conductivity detection result is output to the 12-grid LED indicator lamp in FIG. 1 for displaying, and therefore, the display of the thermal conductivity degree is correspondingly carried out according to the lighted format of the LED and the like, for example, when the 12-grid LED indicator lamp is lighted for more than 9 grids, the buzzer sounds, and the measured object is indicated to be diamond.
It can be known that the thermal conductivity detection result of the existing thermal conductivity detection circuit is directly transmitted to the built-in 12-grid LED indicator lamp for display by the detection result output end of the MCU, and the thermal conductivity detection result cannot be output to external equipment, so that compatibility and data transmission with other material detection equipment are realized.
Accordingly, there is a need for a thermal conductivity detection circuit that is more convenient for data transfer and more compatible with other devices.
In one embodiment of the present utility model, the thermal conductivity interface circuit includes a thermal conductivity detection circuit and a transmission interface; the thermal conductivity detection circuit comprises a first control unit and a detection unit; the transmission interface comprises a first interface; the first interface is connected with the detection result output end of the first control unit;
the first control unit is used for controlling the detection unit to conduct thermal conductivity detection to obtain a thermal conductivity detection result, and outputting the thermal conductivity detection result to the detection result output end;
the first interface is used for transmitting the thermal conductivity detection result output by the detection result output end to external equipment.
The first control unit may be a device for controlling in the existing thermal conductivity detection device, such as an MCU (Mirco Controller Unit, microcontroller) or an MPU (Micro Processor Unit, microprocessor), etc., and the detection unit may be a component for thermal conductivity detection in the existing thermal conductivity detection device, such as a thermistor, a probe, a thermocouple, etc., and the present utility model does not particularly limit the structure of the first control unit and the detection unit.
As shown in fig. 2, the embodiment of the utility model connects the first interface on the output end of the detection result, so that the thermal conductivity detection result which is originally displayed in a fixed position and in a fixed manner by the 12-grid LED indicator lamp is directly output to the external device (not shown in fig. 2) through the first interface, thereby realizing the direct reading of the thermal conductivity detection result by the external device and improving the compatibility of the thermal conductivity detection circuit.
Further, considering that the external device may need to perform external control on the thermal conductivity detection circuit, such as a switch for controlling thermal conductivity detection, in addition to the requirement of reading the thermal conductivity detection result of the thermal conductivity detection circuit, in order to improve the integration and control accuracy and uniformity of the material detection device, in one embodiment of the present utility model, the transmission interface further includes a second interface; the second interface is connected with the control signal input end of the control unit;
the second interface is used for transmitting an external control signal to the control unit so that the control unit controls the detection unit to conduct thermal conductivity detection according to the external control signal.
Specifically, as shown in fig. 2, the control signal input terminal is the Vh terminal of the MCU, and the output on the VCC1 terminal of the MCU in fig. 2 is controlled by inputting an external control signal to the Vh terminal, so as to control the operation state of the detection unit. For example, the external control signal may be a signal for controlling whether the thermal conductivity detection is started or not, for example, when the external control signal is a high level signal, that is, the control signal input on the Vh terminal is 1. When the Vh end of the MCU receives a control signal of 1, +5V voltage is output from the VCC1 end of the MCU, so that the probe, the thermocouple and the thermistor are triggered to enter a working state, and thermal conductivity detection is started. Correspondingly, when the external control signal is a low level signal (e.g. 0), the VCC1 output voltage of the MCU is 0, and the detection unit stops the thermal conductivity detection.
Further, in consideration of that the operation state of the thermal conductivity detection circuit may need to be monitored in real time during the operation of the thermal conductivity detection circuit, such as a detection state and a heating state, in one embodiment of the present utility model, the transmission interface further includes a third interface; the third interface is connected with the detection signal output end of the detection unit;
the third interface is used for transmitting the detection signal of the detection unit to external equipment.
Specifically, as shown in fig. 2, the detection signal output terminal includes a thermocouple electric signal output terminal, and the detection signal may be an electric signal generated by a change in electromotive force across the thermocouple in fig. 2. The real-time detection signal caused by the contact of the detected object and the probe is output to the external equipment, so that the monitoring and management of the thermal conductivity detection process are facilitated.
Further, considering that the thermal conductivity detection circuit needs to preheat the probe during the working process, the probe can be formally detected after the preheating is completed, in one embodiment of the present utility model, the transmission interface further includes a fourth interface; the fourth interface is connected with the heating signal output end of the detection unit;
the fourth interface is used for transmitting the heating signal of the detection unit to external equipment.
Specifically, considering that the external device needs to be monitored during the preheating process of the thermal conductivity detection circuit, the existing preheating process is shown by the preheating lamp in fig. 1, and cannot be acquired and monitored by the external device, so that the heating signal of the detection unit can be transmitted to the external device by connecting the fourth serial port to the heating signal output end of the detection unit as shown in fig. 2, thereby facilitating the real-time monitoring of the preheating process of the thermal conductivity detection circuit by the external device without reading the showing condition of the preheating lamp built in the thermal conductivity detection device, and improving the working safety and control efficiency of the thermal conductivity detection circuit.
Further, in order to improve the integration level of the material detection device, the operation or dormancy of the control unit of the thermal conductivity detection circuit may be further controlled, so in one embodiment of the present utility model, the transmission interface further includes a fifth interface; the fifth interface is connected with the power supply signal input end of the control unit;
the fifth interface is used for transmitting an external power signal to the control unit so as to enable the control unit to start.
Specifically, the external power signal may be sent by an external device, and the control unit is started or closed by the external power signal, so that the thermal conductivity detection function can be selected, and the control flexibility of the material detection process is higher while saving energy.
Further, in order to improve the integration level between the material detection circuits and facilitate unified management, in one embodiment of the present utility model, the transmission interface further includes a sixth interface; the sixth interface is connected with the grounding end of the control unit; the sixth interface is for grounding the control unit.
Further, when the MCU is clocked by an internal clock circuit or an external clock circuit (such as TSCLK in fig. 2) to control the thermal conductivity detection circuit to sleep when the thermal conductivity detection circuit does not operate within a preset period, for example, when the thermal conductivity detection circuit does not operate within a preset period such as 5 minutes, the clock circuit sends a signal to the MCU, and the MCU turns off the +5v power supply of VCC1, thereby further saving energy, and avoiding false detection and affecting circuit safety.
In one embodiment of the present utility model, the first interface, the second interface, the third interface, the fourth interface, the fifth interface, and the sixth interface are integrated as a serial port. Specifically, the types of serial ports may include RS232, RS422, RS485, and other common types, and the embodiments of the present utility model are not limited in particular.
The first interface, the second interface, the third interface, the fourth interface, the fifth interface and the sixth interface are integrated in the form of serial interfaces, so that the butt joint of the transmission interface and external equipment is facilitated, and the data transmission efficiency of thermal conductivity detection can be further improved. The detection result and working parameters (such as heating parameters and detection parameters) of the traditional thermal conductivity detector can only be checked locally on the thermal conductivity detector, the detection process and the remote real-time synchronous monitoring of the detection result can not be realized, the external transmission of the detection data of the thermal conductivity detector needs to be manually connected with an external port at the corresponding position on the thermal conductivity detector, and the efficiency and the accuracy are low. According to the utility model, the first interface, the second interface, the third interface, the fourth interface, the fifth interface and the sixth interface are integrated in the form of serial ports on the basis of the existing thermal conductivity detection circuit, when the detection data transmission requirement exists, the serial ports can be directly connected with external equipment in a pluggable mode, and a professional cannot manually connect and identify circuit structures one by one, so that the thermal conductivity detection efficiency and the user experience are improved.
In particular, considering that the RS232 type serial port has strong universality, it is more common in material detection equipment and data processing equipment, so in one embodiment of the present utility model, the serial port includes an RS232 serial port; as shown in fig. 3, the first pin of the RS232 serial port is the fifth interface (referred to as MCU-VCC); the second pin of the RS232 serial port is the sixth interface, namely a sixth interface (marked as MCU-GND); the third pin of the RS232 serial port is the third interface, namely a third interface (marked as PTC signal); the fourth pin of the RS232 serial port is the first interface (marked as MCU LED to LED indication signal); the fifth pin of the RS232 serial port is the fourth interface, namely a fourth interface (marked as a preheating indication signal); the sixth pin of the RS232 serial port is the second interface, i.e., a second interface (denoted as a switching signal).
