[0027] Figure 3 is a flowchart of the implementation of a control method for an orbit circuit protection box provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will be illustrated through specific embodiments in conjunction with the accompanying drawings.

[0030] See Figure 1 , which shows a schematic structural diagram of an orbit circuit protection box 1 provided by an embodiment of the present invention, and is described in detail as follows:

[0031] As Figure 1 shown, the orbit circuit protection box 1 includes a detection module 11, a control module 12, and an interaction module 13; the control module 12 is respectively connected to the detection module 11 and the interaction module 13;

[0032] The detection module 11 is configured to perform signal sampling on the orbit circuit, generate a sampled value, and send the sampled value to the control module 12;

[0033] The interaction module 13 is used to obtain the adjustment value input by the user and send the adjustment value to the control module 12;

[0034] The control module 12 is used to generate a detection value based on the sampled value and the adjustment value, so as to judge the protection effect on the track circuit based on the detection value.

[0035] In this embodiment, the track circuit protection box processes the control signal in the track circuit. For example, the HF4-25A type protection box is mainly used in the 25Hz phase-sensitive track circuit of railways to protect the JRJC type track relay from being interfered by the 50Hz traction current; compensate for the reactive component of the 25Hz signal frequency; reduce the attenuation and phase shift of the 25Hz signal during transmission; ensure the normal operation of the JRJC type track relay.

[0036] To test the protection effect of the track circuit protection box, a detection module 11 is also set in the protection box. Detection is carried out under the protection state of the track circuit protection box, the control signal that has been protected in the track circuit is sampled, and it is judged whether the protected control signal meets the preset conditions, so as to process it in time when the protection effect is insufficient.

[0037] The control module is used to judge whether the protected control signal meets the preset conditions according to the built-in logic. If the detection value exceeds the limit, it means that the protection effect is insufficient, and an alarm prompts adjustment. The interaction module is used to display the specific value of the protected control signal, which is convenient for users to view the specific protection effect. To ensure the accuracy of the protection effect judgment, the manufacturer usually tests the sampled value of the track protection box with the reference voltage signal in the test environment before leaving the factory, and correspondingly sets an adjustment value, and uses the adjustment value and the sampled value to determine the test value, which is used to judge the protection effect and for users to view. However, there may be a difference between the reference voltage adopted by this method and the reference voltage in the actual scenario, and the reference voltages in different usage scenarios are also different. When a fixed adjustment value is built into the track circuit protection box, the adjustment value will not change with the change of the usage scenario, nor can it be adjusted again according to the user's needs. Therefore, it has many adverse effects on the accuracy of the detection result, and the flexibility of the application of the track circuit protection box is also poor. It must be customized for specific usage scenarios, and it is difficult to change the usage scenario after customization.

[0038] In this embodiment, a function of freely adjusting the adjustment value is set for the track circuit protection box to solve the above problems, and a good track circuit protection effect can be achieved for various situations, and false alarms can be avoided.

[0039] In an embodiment of the present invention, the interaction module obtains the adjustment value input by the user. After sampling the track circuit, the control module uses the adjustment value to adjust the sampling value to generate an adjusted detection value. The user can set the adjustment value according to the actual application scenario to accurately adjust the sampling value and obtain an accurate detection value.

[0040] In a possible implementation, the interaction module 13 includes buttons;

[0041] The interaction module 13 is specifically configured to obtain the adjustment value input by the user through the buttons and send the adjustment value to the control module 12.

[0042] In this embodiment, the applicable environment of the track circuit protection box includes the following conditions:

[0043] 1. Ambient air temperature: -25°C to +40°C;

[0044] 2. Ambient air relative humidity not exceeding 95% (when the temperature is +25°C);

[0045] 3. Atmospheric pressure: not less than 70.1 kPa (equivalent to below 3000 m above sea level);

[0046] 4. Vibration frequency: 10 Hz to 150 Hz; acceleration amplitude: 5 m / s2;

[0047] 5. There are no harmful gases and conductive dust around that can corrode metals, damage insulation, and cause explosion hazards.

[0048] Since the track circuit protection box does not need to collect other types of information input by the user, setting buttons on the track circuit protection box can reduce the production cost and maintenance cost of the track circuit protection box, and at the same time simplify the operation steps of the user.

[0049] In a possible implementation, the interaction module 13 further includes a display unit. The buttons include an OK button, an up button, a down button, and a shift button;

[0050] The interaction module 13 is specifically configured to obtain the trigger states of the OK button, the up button, the down button, and the shift button and send them to the control module 12;

[0051] The control module 12 is specifically configured to enter an adjustment state when it is confirmed that a key is triggered, and send the adjustment state to the interaction module 13; determine the adjustment value category based on the triggering conditions of the up adjustment key and the down adjustment key, and send the adjustment value category to the interaction module 13; determine the adjustment position based on the triggering condition of the shift key, and after determining the adjustment position, determine the updated value of the adjustment position based on the triggering conditions of the up adjustment key and the down adjustment key, and send the adjustment position and the updated value of the adjustment position to the interaction module 13; when it is confirmed that the key is triggered again, determine and save the adjustment value based on the adjusted sampling value, exit the adjustment state, and send the adjusted sampling value to the interaction module 13;

[0052] The interaction module 13 is further configured to display the adjustment value category when obtaining the adjustment value category; display the updated value of the adjustment position when obtaining the adjustment position and the updated value of the adjustment position; display the adjusted sampling value after obtaining the adjusted sampling value.

[0053] In this embodiment, the user uses the above operations to finely adjust the number displayed by the interaction module, that is, the number displayed by the interaction module after fine adjustment is the detection value set by the user. During the user's fine adjustment operation, the control module records the values of each position in real time, and after the user confirms that the adjustment is completed, saves the adjusted sampling value, and calculates the adjustment value based on the sampling value collected by the detection module 11, so as to use this adjustment value to adjust the sampling value during subsequent detection.

[0054] In a possible implementation manner, the sampling value includes a phase sampling value, the adjustment value includes a phase adjustment value, and the detection value includes a phase detection value.

[0055] In this embodiment, the track circuit protection box is further configured to reduce the attenuation and phase shift of the signal during transmission. To detect the protection effect of the phase shift, it is necessary to collect and judge the phase of the signal. Correspondingly, adjusting the phase can ensure the detection effect of the phase.

[0056] In a possible implementation manner, the control module 12 is further configured to send out a phase anomaly alarm signal when the phase detection value is not within the preset phase range.

[0057] In this embodiment, if the phase detection value is not within the preset phase range, it indicates that the protection effect of the phase shift is insufficient, and it is necessary to prompt the staff to perform debugging and processing.

[0058] In a possible implementation manner, the sampling value includes a voltage sampling value, the adjustment value includes a voltage adjustment value, and the detection value includes a voltage detection value.

[0059] In this embodiment, the track circuit protection box performs reactive power compensation on the signal and reduces the attenuation during signal transmission. The effect of reactive power compensation and attenuation reduction can be judged through voltage detection.

[0060] In a possible implementation manner, the control module 12 is further configured to send out a voltage anomaly alarm signal when the detected voltage value is less than a preset voltage threshold value.

[0061] In this embodiment, when the detected voltage value is less than the preset voltage threshold value, it indicates that the effect of reactive power compensation and attenuation reduction is insufficient, and it is necessary to prompt the staff to perform debugging and processing.

[0062] In a specific embodiment, the layout of the keys and the display unit of the track circuit protection box is as Figure 2 shown. The user can finely adjust the phase angle and the track voltage. Long press the "Confirm" key and the "③" key to enter the fine adjustment interface, and use the keys "①", "②", and "③" to adjust the digital size of the digital tube on the display board at the relative position. After the adjustment is completed, press the "Confirm" key to confirm.

[0063] Key ① controls the digital on the digital tube of the display board to shift to the right;

[0064] Key ② adjusts the digital size of the digital tube at the relative position "upward";

[0065] Key ③ adjusts the digital size of the digital tube at the relative position "downward".

[0066] This product monitors the track circuit in real time and displays the voltage and phase states. When the track voltage and phase exceed the user-set threshold range, the indicator light lights up:

[0067] a) When the track voltage < 10V, the occupied red light is on;

[0068] b) When the track voltage > 10V, the idle green light is on;

[0069] c) When the phase exceeds the range of 90° ± 30°, the warning yellow light is on.
