Description
Technical Field
The invention relates to the technical field of broadcast television and satellite communication, in particular to a satellite antenna snow removal controller and a satellite antenna snow removal system.
Background
In China, the transmission and distribution of broadcast television signal sources nationwide depends on geostationary satellite transmission and broadcast and television national backbone network (optical cable) transmission. Because the capacity of the national trunk network of broadcasting and television is limited, the program transmission of a central television station is only carried at present, and the local satellite programs such as provincial stations and the like can only be transmitted by a synchronous satellite, and in fact, the remote transmission of the broadcasting and television of all countries in the world including China almost depends on a satellite transmission platform.
Compared with optical cable transmission, the transmission reliability of a synchronous satellite is much worse, and because the distance between the synchronous satellite and the ground is far, the diameters of reflecting surfaces of ground transmitting and receiving antennas are required to be as large as possible so as to ensure the signal intensity of a receiving end, and even if the signal is transmitted, the transmission signal is still easily interfered. The invention relates to a method for solving interference caused by snow falling and icing in winter, in particular to electromagnetic wave interference such as interference of 5G signals, and interference caused by natural environments such as rabdosia, rain, snow and the like.
The satellite antenna is an ellipsoid, for the receiving antenna, a tuner is fixed at the focus of the receiving antenna, a weak signal from the satellite is just converged to the position of the tuner through the reflection of the ellipsoid, and the weak signal is amplified and subjected to frequency reduction and then sent to a satellite receiver to be decoded to obtain a corresponding signal. And if the user is snowy and snow is accumulated on the antenna reflection surface, on one hand, signals can be scattered in a certain proportion, and on the other hand, signals which should be converged to a focus are shifted and deviated from the high-frequency tuner at equal intervals along with the thickening of the accumulated snow, so that the signals received by the high-frequency tuner are attenuated until no signal is output. Similarly, the same applies to the transmitting antenna, because of the change of the focal position, the signals to the geostationary satellite are attenuated, and the icing condition is similar. Therefore, snow removal is a necessary link to ensure the normal operation of satellite communication in snow.
How to remove snow for satellite antenna, the situation that knows at home and abroad is still a large amount of manual snow removal, and for a small antenna which is not high above the ground, the manual snow removal is not difficult, but a plurality of antennas are often arranged at high positions on the roof, are large-caliber antennas, are high above the ground, and people need to climb to a pan surface to remove snow. On one hand, the receiving performance is easily influenced by the deformation of the reflecting surface; on the other hand, the reflecting surface is slippery in snow days, so that personal injury risks are high, and particularly snow removal is needed late at night.
For some important satellite antennas, an automatic snow removing technology can be adopted, but no mature and universal automatic snow removing facility exists in China at present, common devices comprise electric heating snow melting, hot air blower snow removing, compressed air snow blowing, mechanical scraper snow removing, water spraying snow removing and the like, the common devices have the characteristics of the common devices, but the defects are obvious, such as severe power consumption, low efficiency, poor snow removing effect and the like. Often, the snow removal facility of each antenna is equivalent to a project, and the transportability is poor; for the occasions with a plurality of antennas, management also becomes burden, for example, for electric heating snow melting, if the electric heating is simultaneously started, heavy current may cause overload tripping of a power supply line and the like, or a compressed air nozzle is simultaneously started, wind pressure is reduced, snow blowing capacity is reduced, so that snow removal is mainly performed in a manual and automatic combination mode in practice.
Because the satellite antennas produced by different manufacturers are different in size and structure, the snow removing device is designed by considering not only the mechanical structure but also the use region (the weather difference between the south and the north has different requirements on snow removal), and further considering the control of single-antenna snow removal and multi-antenna snow removal, so that each unit condition is different, the satellite antenna is an independent project, and the reconstruction cost is high; although several modes of snow removal strategies can be selected, the snow removal strategies cannot be combined with actual compiling, the operation cost is always high after modification, the problem of low efficiency is difficult to solve, and finally, the idea of automatic snow removal modification is abandoned by many units.
If can peel off satellite antenna snow removal controller from traditional automatic snow removing device, become the system by oneself, adopt general intelligent design: satisfy the control of different snow removals modes and the customization of individualized snow removals tactics on the one hand, on the other hand can realize the management of removing snow in unison to numerous antennas of quantity, lets the electrical load steady, let the air compressor machine air-out stable, realizes high-efficient low consumption snow removal. The automatic snow removal can be conveniently popularized and applied by being combined with satellite antenna manufacturers.
Based on this, the present application is proposed.

Detailed Description
The present invention will be described in further detail with reference to examples.
As shown in fig. 1, the networking block diagram of the general snow removal system in this embodiment includes a plurality of acquisition controllers, a monitoring private network, a snow removal monitoring server, and an attached network facility, where the attached network facility includes a field camera, a mobile phone control interface, and the like, and the mobile phone control interface is used for a mobile phone to log in the snow removal monitoring server. The camera and the mobile phone are provided with network interfaces and can be directly connected to the snow removal monitoring server through wires or wireless, wherein the camera transmits images of the satellite antenna on site to the snow removal monitoring server, and the mobile phone generally provides parameter display and manual control functions.
And the monitoring private network is used for data transmission between all the acquisition controllers and the attached network facilities of the outdoor satellite antenna field and the snow removal monitoring server. The monitoring private network adopts two modes of wire and wireless to construct an Ethernet private network.
The collection controller is installed in the outdoor rain-proof sun-proof box body (during wireless networking, need cause the WIFI antenna outside the case or adopt the non-metallic box body) at satellite antenna place, including multiple spot temperature acquisition module, linkage control parameter acquisition module, treater, network interface module and drive output module, plays two functions of parameter acquisition and snow removal control. The collected information comprises whether the snow is blown down, the outdoor temperature, the current temperature of the antenna reflecting surface and the like, and snow removal related parameters such as electric power parameters, water pressure and water temperature, air pressure and temperature, switch valve states and the like; the snow removal drive control is to provide outputs of relay on and off for directly or indirectly starting the snow removal facility; the acquisition controller transmits acquired information to the snow removal monitoring server through the monitoring private network, and simultaneously starts and closes a snow removal executing mechanism (also called a snow removal facility) according to an instruction sent by the server.
The processor is respectively in communication connection with the multipoint temperature acquisition module, the linkage control parameter acquisition module, the drive output module and the network interface module, and the network interface module is used for realizing communication with a monitoring private network. Considering that the arrangement of a network cable at the installation position of the outdoor satellite antenna is inconvenient or at least difficult to standardize, the acquisition controller simultaneously designs a wired RJ45 network port and a wireless WIFI interface in the network, so that convenience is provided for networking.
Wherein, the monitoring of the different regional temperature of plane of reflection under the heating snow removing occasion such as the electrothermal film that the multiple spot temperature acquisition module is mainly wider to the region commonality, this module externally provides two kinds of interfaces, one kind is for supporting the intelligent temperature sensor DS18B20 that the extensive American DALLAS company of present application designed, realizes the single bus multiple spot temperature measurement scheme, another kind is the RS485 interface, hang down a plurality of intelligent temperature acquisition appearance based on the MODBUS agreement, no matter which kind of interface, all can gather the several, tens or more temperature data.
And the linkage control parameter acquisition module is used for acquiring the switching control quantity data and other data except the temperature data and used as a basis for starting or closing the snow removal facility by the snow removal server. The module also provides two interfaces, one is an RS232 interface and is used for collecting data such as voltage, current, power, electricity consumption and the like; another interface is the input of switching variables, which represent in each case one control parameter, for example: whether power electricity is ready, whether the power load is overloaded, whether the pressure of the air pressure bag is qualified, whether the rain and snow sensor detects snow, whether the state of a switch valve is in a ready state, and the like. And a multipoint temperature acquisition module and a linkage control parameter acquisition module of the acquisition controller transmit relevant parameters acquired by a satellite antenna on site to a snow removal monitoring server through a monitoring private network. The number of the acquisition controllers can be 1, and a plurality of the acquisition controllers can also be operated together in a cooperative manner.
The drive output module is used for driving the snow removal actuating mechanism to act so as to complete the snow removal task. Because snow removal methods are various, the drive output only provides a plurality of relay isolation outputs (generally, a relay with the contact capacity of 10A is selected), and the relays sequentially or in combination control subsequent facilities to complete snow removal tasks.
The snow removal monitoring server is arranged in a machine room control room, monitors the temperature, whether snow falls or not in an outdoor satellite antenna receiving area, whether snow is accumulated on the antenna or not and the like by receiving the acquisition information from the acquisition controller, and simultaneously monitors the preparation state of electric power facilities, water, gas or other snow removal modes related to snow removal; and automatically or manually controlling the operation of the snow removal facility according to a preset strategy. And the snow removal monitoring server performs combined operation on the acquired parameters at any time according to the currently selected snow removal strategy, drives or closes the corresponding relay output at any time, and dynamically controls the whole snow removal process.
The snow removal monitoring server at least comprises five modules of an acquisition controller and interface configuration, a snow removal strategy configuration, a database table and parameter corresponding conversion module, video image processing and automatic/manual control management.
The acquisition controller and the monitoring system are universal, and can be adapted to satellite antennas with different specifications, control of different snow removal modes and occasions of single-sided and multi-sided satellite antennas, so that the quantity and meaning of parameters to be acquired, parameters to be controlled, control modes and the like are not the same for specific applications, and the acquisition controller and each port need to be defined and configured through the acquisition controller and the interface configuration module. For example, one satellite antenna corresponds to a plurality of acquisition controllers, temperatures of different areas of the reflecting surface correspond to numbered temperature measuring devices, the relays for driving output respectively correspond to heating of the areas of the transmitting surface, and an input port for linkage control represents what meaning. Only after the general acquisition controller is solidified into an actual system can the output be finally controlled according to the input parameters and the snow removal strategy.
The controller and the system are required to be capable of adapting to snow removal strategies in different snow removal modes due to the general characteristic of the controller and the system, so the snow removal strategy configuration module is used for providing a snow removal strategy customizing function. For electrically heating melted snow: when the rain and snow sensor detects that snow falls, the average temperature of a certain area of the antenna reflecting surface is-10 ℃, and the power electricity is ready, a simple strategy is to turn on a relay corresponding to the heating of the reflecting surface area when the three conditions are met, and turn off the relay to stop heating until the average temperature of the area reaches more than 2 ℃ for a plurality of minutes (the snow is considered to be melted). However, in practice, the electrical load for heating the melted snow is often required to be controlled, if a plurality of reflecting surface areas meeting the conditions are simultaneously arranged, and the reflecting surfaces are simultaneously turned on to heat together, the electrical load is over-limited to trip, so that the strategy also adds the condition of grouping and circulating control output.
In the database table and the parameter corresponding conversion module, the database table is used for storing snow removal strategies, acquisition parameters and data of the driving output process; the parameter corresponding conversion module carries out range or format conversion on the acquired data according to the definition of the interface and stores the data in a table. On one hand, the module performs range or format conversion on the acquired data and then stores the data in a table; on the other hand, aiming at different conditions such as snow size, duration, environmental problems and the like, a plurality of different snow removal strategies can be formulated by combining different specifications of local areas and satellite antennas, and the strategies are stored in a database table for selective calling. In addition, the time and various acquisition parameters of the output of the drive of each relay can be recorded, and a basis is provided for the subsequent analysis and optimization of the snow removal strategy.
Through the on-the-spot image of on-the-spot camera to snow removing monitoring server transmission satellite antenna, the effect of antenna snow removing can be seen directly perceivedly to video image processing module, conveniently optimize the snow removing strategy, also provide the foundation for the manual control snow removing, also can prevent in addition that it is the condition that starts the snow removing that the rain is regarded as the snow by mistake, because the rain and snow sensor divides unclear rain or snow, can combine to judge whether rain or snow according to the warning of rain and snow sensor and outdoor temperature among the automatic control, can have the wrong report condition.
The automatic/manual control management module comprises a collected information monitoring unit, a strategy selection unit, a manual and automatic switching unit, a manual control unit and an automatic control unit, wherein the collected information monitoring unit is used for monitoring relevant parameters of each satellite antenna environment and monitoring relevant parameters of a snow removal facility, the manual and automatic switching unit is used for switching between an automatic mode and a manual mode, the automatic control unit is used for realizing automatic control in the automatic mode, the manual control unit is used for realizing manual control in the manual mode, and the strategy selection unit is used for providing selection of a snow removal strategy.
The snow removal control process of the satellite antenna snow removal controller and the satellite antenna snow removal system comprises the following steps:
s1, according to the early warning of snowing of weather forecast, relevant snow removal facilities are inspected, maintained and prepared in advance, such as: in the special power distribution facility for snow removal, a gate is closed to enable a linkage control parameter acquisition module of an acquisition controller to detect parameters of power electricity readiness, if snow removal is performed by water spraying or blowing, conditions of a water pump, a water pipe, a valve, a water storage tank and the like or an air compressor, an air bag and the like are required to be checked, and the linkage control parameter acquisition module is ensured to detect that a snow removal control mechanism is in a prepared state;
s2, the parameters detected by the acquisition controller are displayed on an interface of the snow removal monitoring server, and the snow removal monitoring server judges whether snow removal needs to be started or not and how snow removal needs to be started according to a snow removal strategy;
s3, when the rain and snow sensor detects rain or snow and the outdoor temperature or the temperature of the antenna reflecting surface is lower than-2 ℃ (which can be set and modified), the system considers that the snow condition is satisfied; and as other linkage control devices are prepared in advance to meet the conditions, the snow removal monitoring server drives the relay to be closed through the network according to a preset strategy to control the snow removal facility to operate.
In order to save energy or safely remove snow, the snow removing process is not carried out by all the antennas and all the reflecting surfaces together, and the snow removing process is intentionally set to be carried out in turn in a certain sequence in a strategy and then repeatedly carried out or all the antennas are suspended after one cycle and then repeatedly carried out.
The general snow removal system of fig. 1 will be put into practical use hereinafter.

The ports of the 2 acquisition controllers can be equally divided, or one acquisition controller can be fully configured at first, and the rest acquisition controllers are configured to the other acquisition controller, and the latter acquisition controller is preferably selected from the perspective of comprehensive utilization of resources during multi-antenna snow removal. In this example, 6 drive output ports (i.e., heating control modules) of the acquisition controller 1 are all used, and 12 temperature measurement points corresponding to these ports in the snow melting zone are disposed to the temperature sampling port. The linkage control parameters of other switching values are firstly configured on the first platform, such as power electricity readiness, load overload detection, rain and snow sensor detection and the like; the data type linkage control is configured on the second station, and data such as voltage, current, power, electricity consumption and the like are transmitted through a load sampling interface;

The configuration of the acquisition controller and the interface and the snow blowing operation conditions are as follows:
firstly, three controllable oscillating compressed air nozzles are arranged on a satellite antenna reflecting surface at intervals of 120 degrees, and snow is blown away from the antenna by compressed air by controlling the oscillation of the nozzles;
secondly, 1 acquisition controller is needed for 3 air bleeding control and 3 nozzle steering control, if other control is needed, such as compressed air heating control, auxiliary lighting control of a night camera and the like, 2 acquisition controllers are needed, the number, the installation position and the like of the air nozzles are adjusted according to actual effects and driving interfaces are also distributed according to actual effects according to different specifications of the satellite antenna;
thirdly, in the application, the temperature collection does not need to collect the multipoint temperature of the reflecting surface, and only needs the outdoor environment temperature; the switching value and data quantity of other linkage control acquisition, a field camera and the like are similar to those of the application example;
