For example, the steps described in this application may be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved. This is not a limitation herein.

[0032] In related technologies, with the continuous improvement of fire-fighting technology, the requirements for fire-fighting are also getting higher and higher. In the continuous updating of test tools, there are professional test tools for smoke sensors, temperature sensors, infrared radiation, flame detectors and other equipment. For temperature-sensing cables and temperature-sensing optical fibers, the traditional heating test is to use the above-mentioned test tools to heat them in the form of hot water or hot air guns. Traditional heating tools are difficult to conduct comprehensive tests on temperature-sensing cables and temperature-sensing optical fibers in extreme environments such as ultra-high or narrow spaces, and it is difficult to accurately control the heating temperature.

[0033] In order to solve the above problems, the present disclosure provides a mobile heating test device for a fire temperature measurement system, which is connected to a shell through a constant temperature heating tube through a connector; a display screen is installed on the shell, and the display screen is electrically connected to a temperature measuring element through a digital-to-analog conversion unit; a battery is installed inside the shell, and is connected to the constant temperature heating tube through a sliding rheostat installed inside the shell, so as to supply power to the constant temperature heating tube; an adjustment knob is installed on the shell, and the adjustment knob is connected to the sliding contact of the sliding rheostat, so as to adjust the heating temperature of the constant temperature heating tube, so that the mobile gat test device can be flexibly used for fire testing without being restricted by space and height, thereby improving the comprehensiveness of the test and the accuracy of the heating temperature control.

[0034] Figure 1 and Figure 2 The figure is a schematic structural diagram of a shell in a mobile heating test device for a fire protection temperature measurement system according to an exemplary embodiment.

[0035] like Figure 1 and Figure 2 As shown, the device may include: a constant temperature heating tube 1, a temperature measuring element, a display screen 3, a battery, a sliding rheostat and a housing 6, wherein:

[0036] The constant temperature heating tube 1 is connected to the shell 6 through a connector; a display screen 3 is installed on the shell 6, and the display screen 3 is electrically connected to the temperature measuring element through a digital-to-analog conversion unit; a battery is installed inside the shell 6 and is connected to the constant temperature heating tube 1 through a sliding rheostat installed inside the shell 6, so as to supply power to the constant temperature heating tube 1; an adjusting knob 7 is installed on the shell 6, and the adjusting knob 7 is connected to the sliding contact of the sliding rheostat, so as to adjust the heating temperature of the constant temperature heating tube 1.

[0037] In an embodiment of the present application, when performing fire-fighting temperature measurement on a temperature-sensitive cable or a temperature-sensitive optical fiber, the staff can hold the shell 6, heat the constant temperature heating tube 1 to the target temperature by adjusting the knob 7, and then fit the constant temperature heating tube 1 to the cable to be tested to heat the cable to be tested. The temperature measuring element collects temperature data in real time, and a trend chart of temperature changes over time is displayed on the display screen 3 until it is shown that the target temperature is heated, and the constant temperature heating tube 1 is separated from the cable to be tested.

[0038] In one embodiment, the temperature measuring element may be a temperature sensor.

[0039] In the embodiment of the present application, a mobile power supply is used for power supply, and no external power supply is required, which solves the problem of no power supply at the test site in some test scenarios. The device is small in size and easy to carry, and can heat long-distance optical fibers at the same time; it solves the extreme environment testing needs in ultra-high or narrow spaces.

[0040] In addition, power banks typically have two capacities on their labels: battery energy and rated energy. It's understandable that battery energy is similar to that of a mobile phone. Rated energy refers to the amount of energy the power bank can convert into other devices when charging them. Because the power bank's battery's discharge cutoff voltage to charge cutoff voltage ranges from 2.5V to 4.2V, it needs to be boosted to convert it to the daily output voltage of 5V or higher. This process results in some energy loss. Furthermore, the rated capacity is followed by a voltage and current specification. For example, the 5V4.5A shown above indicates that the rated capacity is measured at a discharge voltage and current of 5V4.5A. If a different voltage and current are used, the amount of energy that can be discharged may not be the same as the amount that can be discharged at 5V4.5A, so the voltage and current must be additionally marked.

[0041] When using, you should also pay attention to the rated capacity to determine the number of times the mobile phone can be charged. For example, a mobile power supply with a battery energy of 20000mAh and a rated capacity of 12600mAh (5V5.4A) can charge a 5000mAh mobile phone. The actual capacity that can be discharged is 12.6Ah. After multiplying the voltage by 5V, the amount of electricity that can be discharged is 63Wh. Then, for a mobile phone with a 5000mAh battery (5Ah, 19.35Wh), it can be charged about 2.6 times (calculated based on a charging efficiency of 80%, 63×80%÷19.35≈2.6). However, the voltage is not a constant 5V during actual charging, so the amount of electricity discharged by the mobile power supply is not necessarily 63Wh. Therefore, this value can only be used as a reference.

[0042] Because the mobile power supply does not have a suitable charge pump but uses an ordinary step-down module, the temperature control during use is not as high as that of a mobile phone, so the lifespan will be shorter.

[0043] In the embodiment of the present application, since the mobile heating test device proposed in the present application is a heating device, the requirements for the mobile power supply are relatively high. In order to ensure the endurance of the device, the remaining capacity of the mobile power supply used must be tested. The method for testing the remaining capacity of the mobile power supply is as follows:

[0044] When using an ammeter to estimate battery capacity, it's best to use a USB-C ammeter when testing discharge at a USB-C port, and a USB-A ammeter when testing discharge at a USB-A port. Plug the ammeter into the power bank for testing, and discharge according to the voltage and current marked on the rated capacity of the power bank. During the test, record the amount of power that can be discharged (you can check the power consumption, which is generally considered to end when the power bank automatically stops discharging). Compare this with the initial rated capacity to estimate the maximum capacity of the power bank. In other words, by estimating the maximum capacity of the power bank, you can estimate the battery's usage life and avoid situations where insufficient power during use could affect the heating test process.

[0045] In one embodiment, the remaining battery life can be determined based on a pre-set mapping table including the correspondence between battery capacity, usage time and type of constant temperature heating tube 1 (such as heating tube length), as well as the current battery usage time and heating tube type, and subsequent heating test work can be arranged based on the remaining usage time to avoid invalid testing caused by sudden power failure of the equipment.

[0046] As an example, the resistance range of the sliding rheostat mentioned above refers to the range between its maximum and minimum resistance values. This range is usually specified by the manufacturer, and users can choose the appropriate resistance range based on their needs. Resistance accuracy refers to the deviation between the actual resistance value of the sliding rheostat and its nominal resistance value. This parameter is very important for applications that require precise control of the resistance value. Operating current: The operating current of a sliding rheostat refers to the maximum current it can withstand under normal operating conditions. If this current is exceeded, the rheostat may overheat or even be damaged. Operating voltage: The operating voltage of a sliding rheostat refers to the maximum voltage it can withstand under normal operating conditions. If this voltage is exceeded, the rheostat may break down, causing a short circuit. Linearity: Linearity refers to the relationship between the resistance value of a sliding rheostat and its sliding position. An ideal sliding rheostat should have a completely linear relationship, meaning that the resistance value is directly proportional to the sliding position. However, in reality, due to manufacturing process and material limitations, the linearity of sliding rheostats often has some deviation. The temperature coefficient refers to the degree to which the resistance value of a sliding rheostat changes with temperature. This parameter is very important for devices that need to operate within a wide temperature range. Lifespan refers to how long a sliding rheostat can continue to work under normal operating conditions. This parameter is usually provided by the manufacturer, and users can choose the appropriate lifespan according to their needs. There are two installation methods for sliding rheostats: vertical and horizontal. Vertical sliding rheostats are usually used in high-voltage, high-current applications, while horizontal sliding rheostats are suitable for low-voltage, low-current applications. There are usually two types of contact materials for sliding rheostats: one is metal, such as copper or aluminum; the other is carbon film. Sliding rheostats with metal contact materials usually have good electrical conductivity and wear resistance, but are more expensive; sliding rheostats with carbon film contact materials are cheaper, but have poorer electrical conductivity and wear resistance.

[0047] In some embodiments of the present application, Figure 4-6 As shown, there are multiple constant temperature heating tubes 1, each of which has a different length; the connecting piece is a movable clip 12; wherein:

[0048] Each constant temperature heating tube 1 is fixedly connected to a movable clip 12 via a connecting unit 11;

[0049] The top of the housing 6 is provided with a slot matching the movable clip 12 , and the movable clip 12 is engaged with the slot.

[0050] In the embodiments of this application, Figure 4-6The constant temperature heating tubes 1 are of different lengths. Since distributed monitoring points are usually used on the cable to be tested to monitor the changes of the cable after heating, in order to cover the corresponding measuring points during the heating process, a variety of constant temperature heating tubes 1 of different lengths can be configured. According to the actual distribution of the monitoring points, the constant temperature heating tube 1 of suitable length is selected for heating, thereby improving the flexibility and efficiency of the test.

[0051] In some embodiments of the present application, Figure 2 As shown, the display screen 3 is used to display the mapping relationship between the temperature data collected by the temperature measuring element and time.

[0052] In the embodiment of the present application, a display is used to display the temperature change, so that the staff can intuitively observe the current temperature change and control the temperature of the constant temperature heating tube 1 based on the temperature change.

[0053] In some embodiments of the present application, there are multiple batteries, and the battery capacity of each battery is different; a battery mounting slot 62 is provided inside the shell 6, and the battery mounting slot 62 is used to install batteries of different capacities.

[0054] In one embodiment, batteries of different capacities can be replaced according to actual needs.

[0055] In some embodiments of the present application, Figure 3 As shown, a power charging port 61 is provided on the housing 6 , and the power charging port is connected to a battery provided inside the housing 6 .

[0056] In one embodiment, the charging port can be used to directly charge the battery installed in the housing 6, thereby improving the convenience of charging the battery.

[0057] In some embodiments of the present application, the area adjacent to the knob on the shell 6 is also marked with a temperature value to indicate the target heating temperature of the constant temperature heating tube 1.

[0058] In one embodiment, Figure 1 As shown, the end of the knob can correspond to the marked temperature value, so that the user can intuitively correspond the degree of rotation of the sliding contact of the sliding rheostat to the temperature.

[0059] In some embodiments of the present application, the display screen 3 is also used to display the on / off status of the mobile heating test device and the on / off status of the constant temperature heating tube 1.

[0060] As an example, the following steps may be used to perform fire temperature measurement using the mobile heating test device for a fire temperature measurement system proposed in this application:

[0061] When in use, directly clamp the device to the temperature-sensitive optical fiber or temperature-sensitive cable test site through the movable clip 12;

[0062] Click the "Power On" button to turn on the device;

[0063] Click "Heating On" to turn on the constant temperature heating tube 1, and adjust the temperature to the test required range of 0 to 315℃ through the circular sliding resistor on the front;

[0064] When the knob arrow of the sliding rheostat points to the temperature number, the device is heated to the specified temperature. At the same time, check the positive time coefficients of the X-axis and Y-axis on the display screen 3, and at the same time check whether the alarm host receives the fire alarm signal.
