Description

Technical Field

[0001] The invention relates to the technical field of time synchronization testers, in particular to a split portable time synchronization tester. Background Art

[0002] A time synchronization detector is a tool used to detect and analyze the accuracy of time synchronization between systems or devices. It can evaluate the time consistency of different devices or systems and ensure their coordination in synchronous operations. It is widely used in fields such as networking, communications, and industrial automation to improve the overall performance and stability of the system.

[0003] The split time synchronization tester can flexibly perform multi-point detection, which is convenient for testing and measurement in different environments. However, the split time synchronization tester requires the split unit to send a signal to the main body, and the main body calculates the time deviation after receiving it. However, it takes a certain amount of time for the split unit to transmit to the main body, which will produce a certain delay, resulting in a certain deviation in the calculated data. In addition, in order to facilitate the use of the split unit, both the main body and the split have independent batteries. When the power is insufficient, multiple connection interfaces need to be charged, and the operation is more complicated. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a split portable time synchronization tester, which solves the problems of a certain delay caused by a certain time required for transmission from the split unit to the main body and inconvenient charging.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a split portable time synchronization tester, comprising:

[0006] A main body shell for supporting the tester, both sides of the top of the main body shell are provided with installation slots, the interior of the installation slots are slidably connected with a split shell, the interior of the main body shell is provided with a main measuring unit, the main measuring unit includes a data transmission module B, a data processing module, a time source module and a delay detection module, the interior of the split shell is provided with a split measuring unit, the split measuring unit includes a data transmission module A, a data formatting module and a time signal receiving module, and a display screen is fixedly connected to the middle of the front end of the main body shell;

[0007] Used to install multiple lower magnetic arc plates in the middle of the inner side of the slide groove, the main battery is fixedly connected to the inside of the main shell, and the split battery is fixedly connected to the inside of the split shell. The main battery charges the split battery through electromagnetic induction of the coil, and the lower magnetic arc plates are fixedly connected on both sides of the bottom end of the split shell. The lower magnetic arc plates are magnetically connected to each other, and the top of the split shell is fixedly connected to a toggle plate.

[0008] Preferably, the coil includes a transmitting end coil located inside the mounting slot, the inner bottom end of the split shell is located on the inner side of the lower magnetic arc plate and is fixedly connected to a receiving end coil, the receiving end coil is electrically connected to the split battery, and the main battery is electrically connected to the transmitting end coil respectively.

[0009] Preferably, bidirectional transmission is performed between the data transmission module A and the data transmission module B, the delay detection module detects the delay data, and the data transmission module B is connected to the data processing module.

[0010] Preferably, the data processing module calculates the time deviation of the split measurement unit according to the time source module.

[0011] Preferably, the formatting module is connected to the time signal module to simplify the time signal module data.

[0012] Preferably, both sides of the split housing are provided with limit slide grooves, and a plurality of signal interface grooves are evenly provided inside the outer limit slide grooves.

[0013] Preferably, both sides of the interior of the installation slide groove are fixedly connected to limit strips, and the exterior of the limit strips is slidably connected to the interior of the limit slide groove.

[0014] Preferably, warning lights are fixedly connected to both sides of the front end of the main shell, and the warning lights are electrically connected to the main measuring unit.

[0015] Working principle: When using the device, push the split housing outward through the toggle plate to take it out, place the split housing at the device to be tested, connect it to the device through the signal interface slot, and connect the split housing to the main body through the local area network. The signal interface slot receives the pulse signal generated by the device, and the time signal receiving module can collect PPS, I RI GB, NTP and other signals are transmitted to the data formatting module, and the data is encoded and packaged in a standardized format so that the main control unit can correctly decode and process it, and then transmitted to the data transmission module A to the data transmission module B, and the transmission module B then transmits the data to the data transmission module A. The delay detection module detects the round-trip time of the signal, and transmits the data and the delay time together through the data transmission module B to the data processing module, so as to calculate the time deviation, reduce the data deviation caused by the delay, and make the calculation more accurate. When the deviation is too large, the corresponding warning light flashes red, and flashes green. After completing the inspection and adjustment of the equipment, the split housing is slid back into the inside of the installation slide groove, and the limit slide groove is attached to the outside of the limit strip to limit the split housing. When the bottom end of the lower magnetic arc plate contacts the top end for magnetic attraction, the main battery is used to generate power for the sending end coil.

The receiving end coil induces current in the alternating magnetic field generated by the sending end coil, thereby charging the split battery. When the device is powered, it only needs to ensure that the main battery has sufficient power to improve the convenience of use.

[0029] When the device is used, the split housing 4 is pushed outward by the push plate 3 to be taken out, and the split housing 4 is placed at the device to be detected, and connected to the device through the signal interface slot 11, and the split and the main body are connected through a local area network. The signal interface slot 11 receives the pulse signal generated by the device, and the time signal receiving module can collect PPS, I RIG-B, NTP and other signals, and transmit the signal to the data formatting module, encode and package the data in a standardized format so that the main control unit can correctly decode and process it, and transmit it to the data transmission module A to transmit it to the data transmission module B, and the transmission module B then transmits the data to the data transmission module A. The delay detection module detects the round-trip time of the signal, and the specific calculation method is:

[0030]

[0031] Where T round_trip is the total round trip time of the signal;

[0032] The data and the delay time are transmitted to the data processing module through the data transmission module B, so as to calculate the time deviation. The specific calculation method is:
