Description

Technical Field

[0001] The present invention relates to the technical field of signal marking, and in particular to a control system for signal marking. Background Art

[0002] Because the signal markers deployed before mine blasting operations are restricted by the blasting site and have a relatively wide distribution range, after the mine signal marker carrier is placed at the drop point, the influence of low temperatures will cause the signal marker's low-temperature adaptability control to be inconsistent with its normal operating requirements, making the mine signal marker unable to achieve its specified function. As a result, the marker signal cannot be sent stably under its limited mechanical performance. At this time, the digital receiving end cannot obtain the marker signal with a low error margin and cannot ensure that the marker signal is sampled at the optimal time, resulting in a low signal-to-noise ratio, which affects subsequent signal marker processing. To this end, we propose a control system for signal markers. Summary of the Invention

[0006] A further improvement of the present invention is that the general control unit assembly includes an extrusion buffer protection ring, a control element placement plate and a telescopic fastener, the control element placement plate is arranged on the inner side of the extrusion buffer protection ring for isolating and protecting the extrusion buffer protection ring when it is subjected to extrusion force, the marking signal control module is fixed to the bottom of the control element placement plate, the telescopic fastener is fixedly connected to the outer wall of the control element placement plate, and the extended end of the telescopic fastener slides through the control element placement plate.

[0007] A further improvement of the present invention is that the extrusion buffer protection ring is provided with a heat dissipation arrangement cavity, and a ventilation groove cavity is formed between the extrusion buffer protection ring and the control element placement plate, which serves to increase the air circulation path through the heat dissipation arrangement cavity and the ventilation groove cavity.

[0008] A further improvement of the present invention is that the general control unit assembly also includes a closed ring seat fixedly installed on the inner side of the marking carrier, and the extrusion buffer protection ring is slidingly connected to the closed ring seat, thereby realizing synchronous opening and closing of the use status of the heat dissipation arrangement cavity according to the current signal marking carrier arrangement point environment.

After the optimal signal sampling value is obtained under the timing recovery action of the timing recovery control module, it is uploaded to the server through the wireless signal receiving and sending module.

In order to better illustrate the specific embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0017] Example

[0018] See also Figure 1-4A control system for signal marking includes a main control unit assembly 1 and a marking signal control module 2. The marking signal control module 2 is fixedly installed on the main control unit assembly 1. The inner side of the main control unit assembly 1 is provided with a marking point environment adaptation module 3 for adapting and regulating the environment of the signal marking carrier placement point. The main control unit assembly 1 is installed with a control start sensing module 4 for collecting the signal marking carrier placement point environment and then regulating the starting mode of the marking point environment adaptation module 3. The marking point environment adaptation module 3 includes a control conduction gasket 31, an environment adaptation control unit 32 and a connecting support 33. The connecting support 33 is fixedly connected to the top of the control conduction gasket 31. The environment adaptation control unit 32 is fixedly connected to the control conduction gasket 31. After the control start sensing module 4 collects the placement point environment state, it adjusts the conduction temperature required by the control conduction gasket 31 through the environment adaptation control unit 32, thereby achieving environmental adaptation. The connecting support 33 is fixedly connected to the inner side of the signal marker carrier for overall support after assembly. The control start sensing module 4 includes an extension connector 41, an environmental interval change monitoring unit 42, a connector plate 43 inside the marker carrier and a lifting drive unit 44. The extension connector 41 is arranged on the inner side of the total control unit assembly 1, the environmental interval change monitoring unit 42 is fixedly connected to the extended end of the extension connector 41, the connector plate 43 inside the marker carrier is arranged on the top wall of the environmental interval change monitoring unit 42, and the lifting drive unit 44 is fixedly connected to the inner side of the signal marker carrier. After the signal marker carrier arrives at the layout site to collect on-site environmental elements through the environmental interval change monitoring unit 42, the environment adaptation control unit 32 and the lifting drive unit 44 are controlled to start synchronously, and then the height state of the total control unit assembly 1 is controlled by the lifting drive unit 44, so that the control conduction gasket 31 is in partial contact with the total control unit assembly 1 to achieve temperature conduction adapted to the environment.

[0019] In this embodiment, since the general control unit assembly 1, the marking signal control module 2, the marking point environmental adaptation module 3 and the control start sensing module 4 are centrally assembled in the signal marking carrier, they can arrive at the arranged blasting environment point synchronously with the signal marking carrier. After the signal marking carrier arrives at the arrangement point and completes support on the soil surface, the environmental interval change monitoring unit 42 completes the collection of temperature interval elements in a time period under the on-site environment after the signal marking carrier arrives at the arrangement site. In this embodiment, the environmental interval change monitoring unit 42 collects the temperature interval cycle interval of fifteen minutes. After collecting the ambient temperature within the time period, the built-in processor calculates the temperature average. When the temperature average is less than the preset trigger value (-20°C), a synchronous start signal is sent to the environmental adaptation control unit 32 and the jacking drive unit 44. At this time, the jacking extrusion buffer protection ring 11 is pushed by the jacking drive unit 44, so that the extension connector 41, under the contracted state of the pushing force, fits the top surface of the control element placement plate 12 with the surface wall of the control conductive gasket 31, thereby achieving the environmental interval temperature under the workmanship of the environmental adaptation control unit 32. The temperature of the marking carrier is quickly reached to the rated operating temperature. In order to avoid the temperature-conducting surface of the regulating conductive gasket 31 and the control element placement plate 12 being always in the working state, causing the local temperature of the control element placement plate 12 to be too high, which causes the working environment temperature of the marking signal control module 2 to increase excessively, the jacking drive unit 44 is retracted to the radius of the sliding stroke. At this time, the regulating conductive gasket 31 is kept above the control element placement plate 12 and does not contact the control element placement plate 12. The heat dissipation arrangement cavity 111 is in a semi-leakage state at this time, and the heat temperature inside the signal tag carrier is conducted through the ventilation groove cavity 112 and the heat dissipation arrangement cavity 111, so as to keep the tag signal control module 2 in a stable temperature environment, and then before the signal tag is transmitted, the environment required for stably obtaining the signal tag is regulated, so that the tag filtering signal and the signal-to-noise ratio can be stably obtained, thereby ensuring the best signal sampling value, improving the environmental control adaptation effect of the signal tag and the stability of the tag point acquisition signal.

[0020] Among them, the main control unit assembly 1 includes an extrusion buffer protection ring 11, a control element placement plate 12 and a telescopic clip 13. The control element placement plate 12 is arranged on the inner side of the extrusion buffer protection ring 11 for isolation and protection when the extrusion buffer protection ring 11 is subjected to extrusion force. The marking signal control module 2 is fixed to the bottom of the control element placement plate 12, and the telescopic clip 13 is fixedly connected to the outer wall of the control element placement plate 12, and the extended end of the telescopic clip 13 slides through the control element placement plate 12; after the extrusion buffer protection ring 11 is installed inside the signal marking carrier through the support of the connecting piece 43 inside the marking carrier, it is squeezed due to the ventilation groove cavity. The setting of 112 can provide the control element placement plate 12 with an extrusion buffer space. The base end of the telescopic clip 13 is fixedly connected to the outer wall of the control element placement plate 12, and the telescopic end is slidably placed in the heat dissipation arrangement cavity 111 opened in the extrusion buffer protection ring 11. The extrusion buffer protection ring 11 and the control element placement plate 12 are integrated into the assembly by screws passing through the extrusion buffer protection ring 11 and threadedly screwing with the telescopic clip 13, thereby realizing a detachable assembly between the marking signal control module 2 fixed to the bottom of the control element placement plate 12 and the extrusion buffer protection ring 11, and the marking signal control module 2 can be disassembled and removed later.

[0021] Among them, the extrusion buffer protection ring 11 is provided with a heat dissipation arrangement cavity 111, and a ventilation groove cavity 112 is formed between the extrusion buffer protection ring 11 and the control element placement plate 12. The heat dissipation arrangement cavity 111 and the ventilation groove cavity 112 play a role in increasing the air circulation path. The main control unit assembly 1 also includes a closed ring seat 14 fixedly installed on the inner side of the marking carrier. The extrusion buffer protection ring 11 and the closed ring seat 14 are slidably connected, and then the use status of the heat dissipation arrangement cavity 111 is synchronously opened and closed according to the current signal marking carrier arrangement point environment; when the temperature average is less than the preset trigger value (-20°C), the lifting drive unit 44 is in the state of lifting the extrusion buffer protection ring 11 and the control element placement plate 12. In the lifting pushing state, the extrusion buffer protection ring 11 is separated from the extension connector 41, so that the heat dissipation arrangement cavity 111 and the ventilation groove cavity 112 are both in the open state, which is used for heat temperature to regulate the conduction between the conduction gasket 31 and the bottom position of the control element placement plate 12. When the ambient temperature of the signal mark arrangement point itself is at the normal operating temperature and no control change is required, the environmental adaptation control unit 32 is in the unstarted state, and the lifting drive unit 44 is in the contracted state. At this time, the extrusion buffer protection ring 11 is located on the inner side of the closed ring seat 14, and the closed ring seat 14 blocks the heat dissipation arrangement cavity 111 and the ventilation groove cavity 112, keeping the mark signal control module 2 located at the bottom of the control element placement plate 12 in a normal working environment.

[0022] Among them, the marking signal control module 2 includes a sampling point amplitude value acquisition module 21, a timing recovery control module 22 and a wireless signal receiving and sending module 23. The sampling point amplitude value acquisition module 21, the timing recovery control module 22 and the wireless signal receiving and sending module 23 are all fixedly installed at the bottom of the control element placement plate 12. After the signal marking sampling environment is controlled to adapt to the marking signal control module 2 operation environment through the marking point environment adaptation module 3 and the regulation start sensing module 4, the sampling point amplitude value acquisition module 21 collects the filtered signal transmitted in the signal marking carrier, and after the timing recovery control module 22 obtains the best signal sampling value under the timing recovery action, it is uploaded to the server end through the wireless signal receiving and sending module 23; because in the signal marking system, since adaptive equalization and synchronization technology are important links of the system, timing recovery is required when receiving the marking signal. In order to ensure that the sampling point amplitude value obtained by the receiver is sampled at the best time, the marking point environment adaptation module 3 and the regulation start sensing module 4 are adapted to the signal marking carrier layout. The environment needs to be adaptively controlled to ensure that the mechanical properties of the sampling point amplitude value acquisition module 21 when receiving the mark signal meet the working environment with a good temperature, and the sampling is maintained at the optimal time, so that the sampled data has the maximum signal-to-noise ratio, thereby reducing the bit error rate during subsequent signal demodulation. After the sampling point amplitude value acquisition module 21 receives the sampling amplitude value at the optimal time, it is uploaded to the timing recovery control module 22 for timing recovery control processing. The processing method of the timing recovery control module 22 adopts the early-late gate detection algorithm. The error signal is extracted by the difference in amplitude of the two sampling points before and after the optimal sampling point obtained by the sampling point amplitude value acquisition module 21 during the timing error. If the amplitudes of the two sampling values ​​are different, a timing error is generated. When they reach phase synchronization, the amplitudes are the same. At this time, the middle sampling value is the required symbol value. The difference in amplitude values ​​is used to generate an error signal of the symbol timing recovery loop, which is then uploaded to the external server for processing through the wireless signal receiving and sending module 23. The error signal is extracted to obtain the maximum signal-to-noise ratio.
