Description

Technical Field

[0001] It belongs to the field of network transmission technology, involves an information technology industry, and is used in intelligent control technology in various industries. Background Art

[0002] This application is a supporting product of the company's existing achievements. The company's existing achievements and technologies are combined with telephones to form a control platform. The 12 keys of the telephone are used as control buttons. Radio remote control is used to issue radio remote control commands to many objects in the area, realizing the use of radio remote control in the area. However, during the research and development process, serious problems were found:

[0003] There are blind areas and blind spots, which result in the control signal not being accurately transmitted to the object to be controlled; especially in residential areas, where there are complex walls and stacking, which have a serious impact on the signal. As a control function, it is much more stringent than communication requirements. The first reason is that communication can easily avoid blind areas and blind spots by moving, while the control objects in the house have already been placed or naturally positioned and cannot be temporarily moved, such as washing machines, curtains, etc. Second, the control signal is not allowed to be missed, otherwise there will be consequences.

[0004] To solve the above problems, there are also the following difficulties:

[0005] First, the research and development process repeatedly showed that although the effect of increasing the transmission power has improved, it is still difficult to achieve satisfactory results because the residential situation is too complicated. Moreover, the power increase is very large, and it is subject to many constraints, which will also produce negative effects. The data shows that the 315 frequency is suitable for directional reception and transmission. 433 is suitable for scattered transmission in all directions, but experiments have shown that in residential environments, the effects of the two frequencies are not obvious and cannot solve the problem of blind spots in residential areas.

[0006] Secondly, the carrier represented by 315 cannot be solved by traditional synchronous signal amplification in the same area. The synchronous forwarding method must have two or more carriers, which will cause interference and serious signal attenuation. This is completely different from the performance of similar WIFI forwarding bodies.

[0007] Third, because of the reason in the previous point, if it is necessary to increase the number of forwarding lines to produce multiple amplification effects, it will be more difficult.

[0008] Fourthly, also because of the above three reasons, it is very difficult to maintain the authenticity and forward the two different long and short signals for the same object.

[0009] Fifth, the company’s existing achievements are that the control platform can produce three different transmission methods, and the forwarding system should also have three different forwarding methods to cooperate, which increases the difficulty.

[0010] The above problems are not only to improve the performance of the company's existing achievements, but also common problems faced by similar products. If they are not solved, the resulting product will not be a good product. Summary of the invention

[0011] The existing technology of the applicant is integrated with the telephone to form a control platform. The 12 buttons of the telephone are used to issue numerous control commands. After receiving and processing the commands, the control platform forwards the working objects in the control area. Based on the problem that radio remote control reception and transmission have blind spots due to various factors such as the environment, a signal forwarding device is proposed to match the existing research and development results of the applicant. The main purpose is to enhance the signal between radio transmission and reception, and solve the problem of signal blind spots or blind spots in the transmission area, especially in the residential area. Second, the forwarding can achieve the unique object and the forwarding fidelity of the original transmission signal, whether long or short; third, it can cooperate with the forwarding of the three transmission methods of the existing results of the enterprise; fourth, it can achieve the excellent effect of multiple forwarding enhancement and amplification; fifth, it can be widely used in places with radio remote control represented by 315.

[0012] The present application proposes a signal forwarding device, which includes a transmission system, a central control system, and a forwarding system.

[0013] The transmission system mainly includes a radio receiving and decoding part, a time memory part, a radio encoding part, and a coding collection part.

[0014] The main circuit of the receiving and decoding part includes one or more radio decoding integrated circuits, wherein a single-bit output line of the radio decoding integrated circuit is a single-bit output end of the receiving and decoding part; the output end outputs the original signal emitted by the original control platform that is tracked and received, and the signal is accurately connected and transmitted to the time memory part to form a modulation signal channel, and a modulation instruction is issued to the forwarding system, and the signal also provides a central control source signal for the central control system.

[0015] The time memory part includes one or more time memory units, and the main circuit of each time memory unit is a circuit with a memory time constant; the signal input end of a time memory circuit is a one-bit input end of the time memory part, and the signal output end of a time memory circuit is a one-bit output end of the time memory part.

[0016] The radio coding part is composed of one or more transmitting coding integrated circuits. The one-bit data input end of the coding integrated circuit is the one-bit input end of the radio coding part; the output end of the coding integrated circuit is the one-bit output end of the radio coding part.

[0017] Each bit output end of the receiving and decoding part is connected to an input end of the time memory part, and each bit output end of the time memory part is connected to a data input end of the radio encoding part; the corresponding original signal memorized by the time memory circuit still maintains the state of the modulated signal output by the radio encoding part after the decoding and receiving part completes the reception, and the above structure and connection method can transmit and forward one path of the original signal; multiple such identical structures and connections can forward multiple original signals, and each time memory unit memorizes the signal sent by the corresponding original control platform, forming the necessary condition for the forwarding device to copy and forward after the original control platform completes the transmission.

[0018] The coding collection unit has multiple input terminals and one output terminal; each input terminal is connected to each output terminal of the radio coding part. The output terminal of the coding collection unit is the output terminal of the modulation signal of the modulation channel formed in the transmission system, which is connected to the modulation signal input terminal of the forwarding system, and transmits the collected coded modulation signal to the modulation signal input terminal in the forwarding system.

[0019] The central control system includes a sampling unit and a switch unit; the forwarding rules of the forwarding device are controlled, and then the forwarding of multiple rules is increased by adding the central control components.

[0020] The sampling unit has multiple input terminals and one output terminal. Each input terminal is correspondingly connected to the relevant output terminal of the receiving decoding circuit. The output terminal of the sampling unit with the same phase is connected to the control input terminal of the switch unit. The main circuit of the switch unit is an electronic circuit with switching properties. The output terminal of the switch unit, that is, the state control output terminal of the central control system, is connected to control a certain control point of the forwarding system.

[0021] Based on the sampling signal, the sampling unit completely tracks the receiving process of the radio decoding receiving part, and controls the cutoff and conduction of the switch unit according to the sampling result; the logical relationship formed between the whole receiving process and the control output end of the central control system is an interlocking relationship, that is, in the whole receiving process, the central control system status control output end outputs the signal that the forwarding system does not forward the working status. After the reception is completed, the central control system status control output end outputs the signal that the forwarding system can forward the working status, realizing that only the carrier signal represented by 315MHZ exists in the remote control area, avoiding the interference of multiple carriers existing at the same time.

[0022] The forwarding system is composed of remote control lines or devices; the modulation input end of the forwarding system is connected to the modulation signal output end of the coding collection unit, and the control input end of the forwarding system is connected to the status output end of the central control system.

[0023] The radio signal sent by the forwarding system controls the radio remote control receiving object in the corresponding area.

[0024] Among them, the radio receiving and decoding part in the transmission system is used to completely receive the original command signal transmitted by the original control platform, and then connects to the time memory part in the transmission system, and then connects to the radio encoding part, and then connects to the encoding collection part. Through the connection of several parts, a modulated signal channel is formed, and its output modulated signal is connected to the control forwarding system; the central control command issued by the radio receiving and decoding part in the transmission system is connected to the sampling unit of the central control system, and then connected to the switch unit to form a central control channel; the state output end of the central control system is connected to the control point of the control forwarding system to control the forwarding rule; the transmission system, the central control system, and the forwarding system are connected to form the basic forwarding circuit of the forwarding device with dual channels and dual control.

[0025] Among them, the central control system also includes a staggered start unit, the input end of the staggered start unit is connected to the output end of the sampling unit, the output end of the staggered start unit is connected to the control input end of the switch unit, the staggered start unit includes a main circuit of a time circuit with two different time constants, when the original control platform transmits a signal, the staggered start unit is in a state of a first time constant, when the original control platform stops transmitting, the state of the first time constant disappears after being retained for a period of time, and the staggered start unit becomes a state of a second time constant, the two different time constants make the staggered start unit output different state signals, and make the central control system state output end output different states; the staggered start unit tracks the transmission process of the original control platform, and still maintains a certain sampling result time after the original control platform stops transmitting, which is the time of the forwarding start delay of the forwarding device, and the staggered start unit has different time constants, which is used to stagger the forwarding of multiple forwarding devices to ensure that there is only one carrier signal in the remote control area.

[0026] Among them, the central control system further includes a forwarding control part on the basis of the existing sampling unit and the switch unit. The forwarding control part includes a forwarding time process unit and a zeroing unit. The main circuit of the forwarding time process unit is a short-time delay circuit, including an RC delay circuit. The input end of the forwarding time process unit is connected to the output end of the staggered start unit with a consistent phase, or connected to the output end of the sampling unit with a consistent phase. The output end of the forwarding time process unit with a consistent phase is connected to the input end of the zeroing unit. The main circuit of the zeroing unit is a transient time circuit, including a differential circuit. The output end of the zeroing unit with a consistent phase is connected to the zeroing input end of all time memory units in the transmission system. After zeroing, the output of the time memory unit is zero, the data input end of the coding integrated circuit is zero, and the coded modulation signal is not output;

[0027] The forwarding time process unit in the forwarding control part starts the delay program according to the output result of the sampling unit or the staggered start unit. The modulation signal required for forwarding can be ended based on the clearing unit. Therefore, the delay time of the forwarding control part determines the process time of the forwarding program. When the delay in the forwarding control part is the same as the original signal transmission time, the forwarding process time preserves the time transmitted by the original control platform.

[0028] The central control system further comprises a long-time forwarding control part, which comprises an identification unit and an execution unit. The main circuit of the identification unit is a time circuit for delayed start and fast recovery.

[0029] It includes an RC delay circuit; the input end of the identification unit is connected to the output end of the sampling unit or the staggered start unit with the same phase, the output end of the identification unit with the same phase is connected to the input end of the execution unit, the execution unit is a memory circuit with a time constant, and its output end with the same phase is connected to the reset input end of the forwarding time process unit;

[0030] The identification unit tracks the result of the sampling unit or the staggered start unit, that is, it follows the long signal output of the radio receiving part in the transmission system, and after the delay reaches the threshold voltage value of the identification unit, that is, after the time required for the delayed start of the identification unit is reached, it begins to act on the execution unit. The execution unit tracks the output result of the identification unit. When the output of the identification unit disappears, the execution unit still keeps the memory for a period of time, and its phase-matched output end continues to act on the reset input end of the forwarding control part until the execution unit memory time effect disappears naturally. It can produce a delay after the original control platform stops transmitting and the forwarding control part starts the delay effect. The long forwarding control part and the forwarding control part jointly delay time, which is the same as the long transmission time of the original control platform, and performs equivalent fidelity forwarding.

[0031] Among them, the main time circuit of the forwarding time process unit in the forwarding control part is composed of an RC delay circuit, and the output end of the long-time forwarding control part is used to clamp the positive end of the integral capacitor of the RC delay circuit in the forwarding control part, forming a simple line logic of the joint delay effect of the long-time forwarding control part on the forwarding control part.

[0032] Among them, the output end of the switch unit of the central control system is the state control output end. One of the connection relationships with the forwarding system is to use the state control output end to control the power input end of the forwarding system; the other is to use the state control output end to control the modulation signal input end of the forwarding system.

[0033] Wherein, each bit input end of the sampling unit in the central control system is connected to the learning indication output end of the receiving decoding circuit to form the simplest input end form of the sampling circuit.

[0034] Among them, each time memory unit in the transmission system is composed of a main circuit of a resistor and a capacitor and a peripheral circuit of a diode; each output end of the radio decoding integrated circuit in the transmission system is connected in series with a diode anode connected to the positive end of a memory capacitor, and each memory capacitor anode is connected to a data input end of the coding integrated circuit. The output end of the radio decoding integrated circuit quickly inputs the signal to the capacitor through the diode, and the memory capacitor provides the stored signal to the coding integrated circuit during forwarding.

[0035] At this time, the memory capacitor is cleared in the following way: the peripheral circuit of the clearing unit in the forwarding control part is a plurality of diode cathodes connected together, connected to the output end of the forwarding control part with the same phase, and the positive electrode of the diode is respectively connected to the positive end of each memory capacitor, so that each memory capacitor is cleared when the clearing unit in the forwarding control part outputs a zero signal.

[0036] Wherein, the transmission system further comprises a program control circuit unit, and the program control circuit unit comprises a plurality of program connection elements;

[0037] Each signal output end of the radio decoding integrated circuit is connected to the reset input end of the previous time memory unit through a program connection element. When the current signal comes, it is received and memorized, and the residual information of the signal before memory is synchronously eliminated. After the original signal ends, the program of this signal is forwarded.

[0038] advantage

[0039] 1. A signal forwarding device, including a transmission system, a central control system, and a forwarding system; the transmission system is mainly composed of a receiving part composed of one or more radio receiving and decoding integrated circuits; a memory part composed of multiple time memory circuits, a coding part composed of one or more radio coding integrated circuits, or a coding collection part of gate circuit nature; each bit output end of the receiving part is connected to the corresponding input end of the memory part, the corresponding output end of the memory part is connected to the corresponding input end of the coding part, the output end of the coding part is connected to the input end of the collection part to form a modulation signal channel, and the channel output modulation signal controls the modulation input end of the forwarding system. When the receiving part outputs, it can output a modulated signal under the action of the memory part.

[0040] The central control system is basically composed of a sampling unit of an OR gate circuit and a switching unit of an electronic switch.

[0041] The signal output by the receiving part is connected to the input end of the sampling unit, and the output end of the sampling unit is connected to the control input end of the switch unit. The switch unit controls the control point of the forwarding system, forming the second control method of the central control channel over the forwarding system. The control logic of the central control system is that the signal of the receiving part and the forwarding form an interlocking relationship, that is, when the receiving part has a signal output, the state output end of the central control system outputs a signal that is not forwarded; conversely, the state output end of the central control system outputs a signal that can be forwarded;

[0042] In summary, the first characteristic of the forwarding device is that, under the dual control of the modulation central control dual channels, the forwarding function mode can be formed after the original signal stops sending, which establishes the basis of the present invention. Because the carrier remote control area represented by 315 cannot allow two carriers to exist, otherwise the signal will not be enhanced, but will be greatly attenuated.

[0043] 2. The central control system also includes a staggered start unit, which is connected between the output end of the sampling unit and the control input end of the switch unit; the staggered start unit includes a main circuit of a time circuit with two different time constants, and the different time constants present two state signals, so that the state output end of the central control system outputs different states; the staggered start unit tracks the transmission process of the original control platform, and keeps the sampling result for a certain period of time after the original control platform stops transmitting, which is the extended time of the forwarding start of this forwarding device. The staggered start unit has different time constants, which is used to stagger the forwarding of multiple forwarding devices to ensure that there is only one carrier forwarding signal of one forwarding device in the remote control area.

[0044] To sum up, the second characteristic of the forwarding device is that when there are multiple forwarding devices in the remote control area, each forwarding device adopts a different time constant in the staggered start unit, which can avoid the simultaneous existence of multiple carriers and realize the common use mode of multiple forwarding devices, thereby improving the space.

[0045] 3. The central control system includes a forwarding control part on the basis of the existing sampling unit and the switch unit. The forwarding control part includes a forwarding time process unit, hereinafter referred to as the forwarding unit, and a zeroing unit. The main circuit of the forwarding time process unit is a short-time delay circuit, including an RC delay circuit. The input end of the short-time delay circuit is either connected to the output end of the staggered start unit with a consistent phase, or connected to the consistent output end of the sampling unit. The output end of the forwarding unit with a consistent phase is connected to the input end of the zeroing unit. The main circuit of the zeroing unit is a transient time circuit, including the simplest differential circuit. The output end of the zeroing unit with a consistent phase is connected to the zeroing input end of all time memory units in the transmission system. After zeroing, the memory output of the memory circuit is zero, the data input end of the coding integrated circuit is zero, the coded modulated signal is not output, and the forwarding is ended. The delay of the forwarding control part determines the time of the forwarding process.

[0046] In summary, the third characteristic of this forwarding device is that when the delay in the forwarding control part is the same as the original signal transmission time, the forwarding process time preserves the original control platform transmission time; it can be adjusted to a forwarding mode in which the original signal is forwarded for a short time.

[0047] 4. The central control system also includes a long-term forwarding control part, which includes an identification unit and an execution unit. The identification unit is the main circuit of the electronic circuit containing the delayed start, which includes the simplest RC delay circuit; the input end of the identification unit is connected to the output end of the sampling unit or the staggered start unit with the phase matching, and the output end of the identification unit with the phase matching is connected to the input end of the execution unit. The main circuit of the identification unit is a time circuit with slow delay start and fast recovery; its output end with the phase matching is connected to the input end of the execution unit; the execution unit tracks the output result of the identification unit. When the output of the identification unit disappears, it will still keep the memory for a period of time. Its output end with the phase matching has been acting on the reset input end of the forwarding time process unit in the forwarding control part until the execution unit memory time effect disappears naturally, which can produce a delay after the original control platform stops transmitting and the forwarding control part starts the delay effect. The long-term forwarding control part and the forwarding control part jointly determine the time of the forwarding process.

[0048] In summary, the fourth characteristic of the forwarding device is that when the long forwarding control part and the combined delay time of the forwarding control part are the same as the long transmission time of the original control platform, the forwarding preserves the long transmission time of the original control platform.

[0049] 5. The transmission system also includes a program control circuit unit, which may include multiple program connection elements; each signal output end in the radio decoding integrated circuit is connected to the reset input end of the previous time memory unit through a program connection element. When the current signal comes, it is received and memorized, and the residual information of the signal before memory is synchronously eliminated. After the original signal ends, the current signal is forwarded.

[0050] In summary, the fifth characteristic of the forwarding device is that the forwarding device can sequentially forward the original transmission signal, and can be used to control and monitor a large number of nodes, such as 100 nodes.

[0051] 6. This forwarding device has the above five characteristics. Therefore, it can produce forwarding corresponding to three transmission modes in coordination with the existing achievements of the enterprise, which greatly improves the performance of the achievements.

[0052] 7. It can be equipped with batteries, reliable operation, and will not miss any signal. It can be used in high-end places. It can also be conveniently used in places without AC power.

[0053] Because the present invention is in a normal dormant state, the power consumption during forwarding is at the milliampere level.

[0054] 8. When used alone or in multiple places, no software, related docking and processing are required, making it easy to use.

[0055] 9. It retains all the advantages of the remote control transmitting circuit.

[0056] 10. High cost performance, thus has a broad application space. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] This is one of the many research achievements of the enterprise. The benefits of the multiple achievements are: designing a new electronic technology circuit system, that is, an electronic circuit system with powerful information processing functions, receiving the key signal of the telephone transmission network, and not using the popular technology of combining single-chip microcomputer and broadband to process the signal, which produces multiple advantages. One of them is that it can realize the control of many control objects. The second benefit is: the existing achievement technology of the applicant is integrated with the telephone to form a control platform. The control platform has two functions. One is to connect the control platform with an external mobile phone or other communication tool, and the external mobile phone or other communication tool sends a control instruction. After the control platform receives and processes it, it combines the network to control the radio remote control to control many objects in the control area. The second is that the 12 buttons of the control platform telephone landline can also be directly operated to send control instructions. Through the radio remote control transmission method, many controlled objects in the area are directly controlled. The two operation methods form a second control method in the area using the radio remote control method, which is an excellent function. The present invention mainly serves this function.

[0080] The reason why the present invention is needed is that the existing achievements control many objects and the area they belong to is large, so it is inevitable that there are blind areas and blind spots; in addition, radio transmission and reception are greatly affected by natural factors such as weather changes; secondly, research shows that if it is used in a residence, the complex walls and stacking in the residence will have a serious impact on the signal. Blind areas and blind spots are inevitable, and repeated research shows that they cannot be solved by increasing power; thirdly, as a control function, it is much more stringent than communication requirements. The first reason is that communication can easily avoid blind areas and blind spots by moving, and can also repeat content to make up for unclear calls, while the control objects in the residence have long been placed or naturally positioned and cannot be temporarily moved, such as washing machines, curtains, etc. It is particularly important that the control signal is not allowed to be missed, otherwise there will be serious consequences.

[0081] The success of the forwarding device of the present invention can also enrich network transmission products. For example, the technology similar to WIFI is generally used now, which consumes power at the ampere level, so long-term operation increases the difficulty of matching batteries. The forwarding device is normally in a dormant state that consumes almost no current. The power consumption during the forwarding process is at the milliampere level, so it can be matched with batteries, which is not only more convenient and flexible to use, but also more importantly, it will not lose important command signals due to power failure accidents. In addition, there are a series of advantages that will not be repeated.

[0082] The implementation of the present invention has the following difficulties:

[0083] First, the carrier transmission represented by the 315 frequency does not allow two or more carriers to exist at the same time, so it is impossible to use the method of synchronous transmission and forwarding, which adds a lot of additional technical difficulty; second, if two forwarding devices, or three, are needed, the difficulty is further increased; third, in the case of realizing the unique correspondence of the forwarding object, it is also necessary to ensure that the forwarded original signal is in an undistorted state of slightly longer or shorter transmission. For example, if the original signal is transmitted for a slightly longer time, after completion, the forwarding device forwards it for a slightly longer time. On the contrary, if the original signal is transmitted for a short time, after completion, the forwarding device forwards it for a short time; the fourth difficulty is that the company's existing results can realize three types of transmission, so the forwarding device of the present invention should correspond to the forwarding of three transmission methods. In addition, the forwarding device should also maintain a power-saving state so that it can be easily equipped with a battery.

[0084] To sum up, in order to effectively solve the various problems of radio remote control forwarding, this application proposes a signal forwarding device. Obviously, this device must be creative and use a combination of multiple characteristic lines to overcome the above-mentioned multi-point problems.

[0088] A specific embodiment of a signal forwarding device is as follows:

[0089] 1. The present invention provides a signal forwarding device that forms a dual-channel dual-control basic forwarding circuit, and its implementation and description.

[0090] The basic forwarding circuit only includes the basic units of the transmission system 1, the central control system 2, and the forwarding system 3.

[0091] Description of the delivery system 1. As shown in Figure 2.

[0092] The circuit mainly includes a radio receiving and decoding part Y, referred to as the receiving part Y; a time memory part J, referred to as the memory part; a radio encoding part B, referred to as the encoding part; and a coding collection unit H.

[0093] The main body of the receiving part is composed of one or more radio decoding integrated circuits, wherein a single-bit output terminal of the radio decoding integrated circuit is a single-bit output terminal of the receiving part; the output is the corresponding signal of the original transmission of the platform, and the corresponding signal is accurately transmitted to the memory part, while providing a sampling signal for the central control system in the following text.

[0094] The memory part includes multiple time memory units. If there is only one, it is just a special case. The main circuit of each time memory unit is a circuit with a memory time constant, referred to as a memory circuit. A memory circuit signal input terminal is a one-bit input terminal of the memory part, and a memory circuit signal output terminal is a one-bit output terminal of the memory part.

[0095] The radio coding part is composed of one or more radio transmitting coding integrated circuits. The one-bit data input end of the coding integrated circuit is the one-bit input end of the radio coding part; the output end of a coding integrated circuit is the one-bit output end of the radio coding part, which outputs the coded modulation signal.

[0096] Each bit output end of the receiving part is connected to one bit input end of the memory part, and one bit output end of the memory part is connected to one bit input end of the radio coding part, so a signal can be forwarded; a large number of identical structures of the transmission system can forward a large number of original signals; each memory unit receives and memorizes the corresponding original signal output by the corresponding receiving part, and when the reception is completed, the memorized signal can continue to act on the input data line of the coding integrated circuit. The structure and connection relationship of the above parts form the important basic characteristics of the present invention, that is, it realizes the necessary conditions for copying and forwarding after the original signal ends.

[0097] Each bit input end of the aggregation part is connected to each bit output end of the radio encoding part. The output end of the coding aggregation unit is the modulation signal output end of the transmission system, which is connected to the modulation signal input end of the forwarding system, and transmits the aggregated coded modulation signal to the coded modulation signal input end of the forwarding system.

[0098] The principle process of linking the above parts is that the receiving part is used to receive and translate the original signal transmitted by the original control platform, and output it to the connected memory circuit for rapid memory storage without missing items.

[0099] The corresponding memory unit stores the received input signal, so after the signal is received, there is still a memory signal acting on the input end of the radio coding part, so that the radio coding part can output a modulated signal.

[0100] Figure 9 shows a representation of a time memory unit formed by an RC capacitor, with a diode for isolation, meeting the requirement of fast charge memory, and RC meeting the requirement of having a memory constant.

[0101] In the example, the receiving and decoding integrated circuit uses TDH6301, and the encoding integrated circuit uses HCS301;

[0102] Description of Central Control System 2:

[0103] exist Figure 1In the embodiment, the basic units of the central control system are the sampling unit 2.1 and the switch unit 2.2; the control requirements of the most basic forwarding logic of the present invention are generated, and after adding various new parts introduced later, forwarding modes with various control rules can be generated.

[0104] In the example, the main circuit of the sampling unit is an OR gate circuit, the input end of the OR gate is connected to the relevant output end of the receiving decoding circuit, tracking the transmission process of the original control platform, and controlling the switch unit according to the sampling result; in the example, the switch unit adopts a switch integrated circuit, and the output end of the switch unit, that is, the state control output end of the central control system, is connected to control a control point of the forwarding system.

[0105] The principle of the central control system is that when the receiving part receives the signal, the output end of the sampling unit outputs a signal with the same phase. This signal prompts the switch unit to be cut off, so that the central control system constrains the forwarding system and cannot forward, ensuring that the area to which the original control platform belongs has only the original unique signal, so that all receiving bodies in the area are not disturbed; on the contrary, when there is no signal input to the sampling unit, that is, when the transmission of the original control platform ends, the sampling unit returns to the initial state, the switch unit is turned on, and the constraints on the forwarding system by the central control system are released, and forwarding can be performed. At this time, the forwarded carrier signal in the area is unique. That is, the original transmission and forwarding signals are interlocked. This forms an important basic feature of the present invention. Because the only carrier signal represented by 315 exists in the remote control area, the foundation for the establishment of the present invention is established.

[0106] Explanation 1: When the forwarding system in the present invention sends a number, it will not cause the receiving part in the present invention to receive the number incorrectly and cause logical disorder. The reason is that due to the characteristics of the rolling code and the learning code, the transmitting and receiving integration must first have a learning pairing program, otherwise they cannot be paired. The receiving and forwarding coding integrated circuits in the present invention have not been paired with each other. Similarly, the receiving decoding integrated circuit in the present invention has only been paired with the control platform transmitting coding integrated circuit for learning, and will only receive the signal transmitted by the control platform. Explanation 2: The main circuit of the sampling unit is composed of a circuit of the nature of an OR gate, including a negative OR gate circuit.

[0107] As shown in FIG8 , the sampling unit input terminal is connected to the learning indication terminal of the receiving decoding integrated circuit, which can reduce the number of input terminals of the OR gate circuit, because one decoding integrated circuit can be realized with only one OR gate input terminal.

[0108] Note three: The switch unit in the example uses the integrated circuit CD4066.

[0109] Description of forwarding system 3:

[0110] The forwarding system is composed of remote control classical lines or devices.

[0111] The radio signal sent by the forwarding system controls the radio remote control receiving object in the corresponding area.

[0112] Using the transmitting template as an example, the signal input terminal of the transmitting template is connected to the modulation signal output terminal of the transmission system, and the state control output terminal of the central control system is connected to the power input terminal of one of the controllable points of the transmitting module in FIG. 7 .

[0113] A signal from the receiving part of the transmission system passes through the memory part, the radio encoding part, and the collection part to form a modulated signal processing channel, hereinafter referred to as the modulation channel, and the modulated signal is used to control the forwarding system; a signal from the receiving part of the transmission system passes through the central control system to form a central control processing channel, hereinafter referred to as the central control channel, which regularly controls the forwarding system. The two channels work together to control the forwarding system, which becomes an important combined feature of the present invention, because this dual-channel dual control method can, on this basis, also produce a variety of special functions described later in the present invention.

[0114] The principle of dual-channel dual control is:

[0115] The transmission system has the necessary conditions for forwarding only when there is a modulated signal output.

[0116] The central control system directly constrains and controls the working state of the forwarding system. In the example, it directly controls the power supply of the forwarding system.

[0117] The system components in the example are not the only example implementation, and may not be the best one, but they are the ones that can clearly illustrate the logical relationship.

[0118] 2. The implementation, principle and related instructions of the staggered start part (hereinafter referred to as the start part) are shown in Figure 3.

[0119] If the control platform and the controlled object are far apart, or other factors lead to the need for multiple forwarding devices to be used simultaneously, and because only the remote control signal carrier represented by 315 in the area is allowed to be unique, the central control system 2 also includes a staggered start unit 2.S, referred to as the start unit, which is connected between the output end of the sampling unit 2.1 and the control input end of the switch unit 2.2; the start unit includes a main circuit of two time circuits with different time constants, and the two different time constants make the start unit output different state signals to make the switch unit output different states; the start unit tracks the transmission process of the original control platform, and still maintains a certain sampling result time after the original control platform stops transmitting. The holding time determines the time for the delayed start of the forwarding of this forwarding device, that is, it includes the time of the forwarding process of the previous forwarding device. The different delay time constants of the start unit allow the forwarding of multiple and multi-level forwarding devices to start at different times, thereby ensuring the uniqueness of the forwarding carrier signal of each forwarding device in the area.

[0120] As shown in FIG3 , the main time circuit of the staggered start unit is composed of an integrating capacitor and a resistor in parallel. The positive electrode of the integrating capacitor is connected to the output end of the sampling unit in phase, the negative electrode of the integrating capacitor is grounded, and the capacitor is connected in parallel with the resistor.

[0121] The starting unit, when the original control platform is launched, the sampling unit starts and changes to the second state, and follows the launch process of the original control platform. It will only return to the second state after the launch of the original control platform stops and the time memory disappears.

[0122] When the sampling unit has a signal such as a high-order signal input, the integrating capacitor will be quickly fully charged. Since the internal resistance of the diode or gate is extremely small, it will quickly become the second state. This state keeps tracking the transmission signal of the original control platform. At this time, the startup unit stores the original signal that is not forwarded.

[0123] When the original control platform ends transmitting the signal, the sampling unit returns to a state of no output, and the starting unit integrating capacitor discharges slowly through the parallel resistor, forming a slightly longer discharge time constant. During this time constant, the forwarding device completely remains in a non-forwarding state because the starting unit controls the switch unit. When the starting unit capacitor is discharged and the starting unit is restored, the switch unit is turned on, and the present invention meets one of the necessary conditions for forwarding.

[0124] The time of discharging the integral capacitor of the start-up unit is the time for the forwarding start delay of the forwarding device, and is also the staggered time left for other forwarding devices to forward. By adjusting the time of discharging the integral capacitor in the start-up unit, the time of the forwarding delay start of the forwarding device can be adjusted, and it is also the time to adjust multiple forwarding devices to avoid mutual interference when they are used simultaneously.

[0125] For example, for the first forwarding device, the starting unit can be omitted. The original control platform stops and forwarding occurs immediately. Starting from the second one, if the starting unit discharge time is 0.05 seconds, this time is the total time after the original control platform stops transmitting and the first forwarding device completes forwarding. That is, forwarding starts after an interval of 0.05 seconds. The same is true for the third... multiple forwarding starting units. The forwarding time of each forwarding line is staggered, and forwarding will not occur at the same time. Therefore, multiple forwarding lines are allowed to exist at the same time.

[0126] Since the time constant of each forwarding line is flexibly adjustable and non-binding, it is entirely possible to achieve different discharge time constants for multiple forwarding devices.

[0127] The objects in the corresponding area will successively receive the signal transmitted by the control platform for the first time and the second forwarding signal generated by the forwarding line, which will inevitably enhance the regional signal strength in one aspect and enhance the reliability in another aspect.

[0128] For completely blind spot control objects, they can smoothly receive the appropriately placed forwarding line signals, so there will be no omissions in receiving instructions, which enhances reliability from the second aspect.

[0129] Although there is a delay in the time constant when multiple repeater devices start up at different times, this time can be very short and it is difficult for humans to feel a significant difference.

[0130] 3. Implementation, function and principle of forwarding control part. As shown in Figure 4.

[0131] The central control system further includes a forwarding control part 2.3, referred to as the forwarding control part, on the basis of the existing sampling unit and the switch unit. The forwarding control part includes a forwarding time process unit 2.31, referred to as the forwarding unit, and a zeroing unit 2.32. The main circuit of the forwarding unit is a short-time delay circuit, such as the RC delay circuit shown in FIG6. The input end of the forwarding unit is either connected to the output end of the start unit with a phase match, or to the output end of the sampling unit with a phase match. The output end of the forwarding unit with a phase match is connected to the input end of the zeroing unit. The main circuit of the zeroing unit is a transient time circuit, including the simplest differential circuit. The output end of the zeroing unit with a phase match is connected to the zeroing input end of all time memory units in the transmission system. After zeroing, the transmission system does not output the coded modulation signal because the data input end of the coding integrated circuit is zero.

[0132] The time-shifting unit in the forwarding control part starts the delay program according to the output result of the sampling unit or the starting unit, and ends the forwarding immediately after the reset unit is activated. The delay time of the forwarding control part determines the forwarding process time. When the delay of this part is the same as the original signal sending time, the forwarding process time is faithful to the original control platform transmission time.

[0133] The above implementation and the resulting logical process of each stage are further explained as follows:

[0134] During the transmission process of the original control platform, the modulation channel outputs a valid signal and the central control channel outputs an interlocking signal, that is, no forwarding signal is generated, and the forwarding system finally forms a non-forwarding state.

[0135] After the original control platform completes the transmission, the modulation channel continues to output valid modulation signals due to its memory function, or when the signal receiving part completes the reception, or when the starting unit starts, the central control channel outputs a valid forwarding signal, and the forwarding system forms a forwarding state.

[0136] Since in this circuit, the memory circuit in the transmission system is adjusted to a long-term memory state, the time when the high level of the memory circuit memory disappears is the time of clearing to stop forwarding. The time from the start of forwarding to the start of clearing is the time of the forwarding process. Therefore, the delay parameters of the forwarding control part determine the forwarding process time.

[0137] By adjusting the delay time to the time when the original signal is transmitted, the forwarding time can form the time when the original signal is transmitted, thus achieving the fidelity of the transmission time during forwarding.

[0138] Since the reset unit is a transient output, it will return to normal immediately after the end, and the transmission system will resume normal function. The next signal reception and forwarding enhanced logic can be carried out.

[0139] The forwarding control part also has the following meanings:

[0140] For example, the transmission system memory element adopts the capacitor measure analysis in the example, which means that only one parameter of the forwarding control part delay is used.

[0141] The related components required for the time constants of many memory circuits in the transmission system can be eliminated, such as not connecting the discharge resistor to the ground. The circuit is greatly simplified, and the time constants in the memory units are unified and consistent during mass production.

[0142] Another important meaning is that it creates good conditions for long-term forwarding of the control part.

[0143] The input end of the forwarding control part can be connected to the output end of the starting unit or the output end of the sampling unit. The only difference between the two is the time constant of the starting effect of the forwarding control part. There is no essential change in other places.

[0144] 4. Implementation, function and principle of long-term forwarding control part 2.5, hereinafter referred to as long-term forwarding part. See Figure 5.

[0145] The meaning of this article is that if the control platform connected to the network sends out a long-term transmission signal, which is referred to as a long signal, then this forwarding device forwards a long-term signal. With the cooperation of the forwarding control part, it can be compatible with the forwarding enhancement of both long and short signals at the same time. The important significance will be introduced later.

[0146] In the central control system, based on the existing sampling unit 2.1, switch unit 2.2, transfer control unit 2.31 in the transfer control part 2.3, and clearing unit 2.32, the identification unit 2.51 and execution unit 2.52 in the long-term transfer control part 2.5 are added.

[0147] The main circuit of the identification unit 2.51 can adopt an RC delay circuit, and the main time circuit of the execution unit 2.52 is composed of two time constant time circuits. The connection relationship is that the input end of the identification unit is connected to the desired output end of the sampling unit or the starting unit of the central control system, and the phase-matched output end of the identification unit is connected to the input end of the execution unit. The phase-matched output end of the execution unit is connected to the reset input end of the forwarding control part. In the forwarding control part shown in Figure 6, the delayed main time circuit of the forwarding unit is an RC integration circuit, and the phase-matched output end of the execution unit directly clamps the positive electrode of the integration capacitor of the forwarding unit.

[0148] The logical principle formed is that if the transmission system receives a short-time signal, since the identification unit of the long-time forwarding control part has not reached the delay time point required by the identification unit, no signal will be output, and the long-time forwarding control part will not produce any effect. That is, the forwarding end instruction output by the forwarding control part is still the original effect. That is, the whole process time of the forwarding time depends on the delay time in the forwarding control part. This time is equivalent to the process time of the original signal using a short-time transmission.

[0149] The second logical principle formed is: if the transmission part receives a long-term signal, the recognition unit of the long-term forwarding control part receives a delayed arrival signal, and its output signal, such as a high-voltage signal, will be transmitted to the execution unit. If the received signal continues, the recognition unit will also continue to output the signal.

[0150] The main circuit of the execution unit is a memory element with a time constant, such as a capacitor and a resistor. When the recognition unit outputs a signal, the memory element in the execution unit generates memory, such as the capacitor is charged to form memory, and maintains it. Because the output end of the execution unit is phase-matched, the delay reset end of the transfer unit of the forwarding control part is clamped. If the received signal continues, the recognition unit will also continue to output the signal, and the execution unit will also continue to maintain this signal, and the central control system outputs a non-forwarding signal.

[0151] The third logical principle formed is that when the received signal ends, the recognition unit stops outputting the signal, and the execution unit will continue to memorize the signal for a period of time due to the memory element, and continue to maintain the clearing effect on the clearing end of the forwarding control part, which prolongs the effect of extending the time of the forwarding control part, forming a long-term forwarding control principle.

[0152] The fourth logical principle formed is that the joint delay effect of the long-term forwarding control part and the forwarding control part can be adjusted to the parameter of the original signal transmission time length, so the forwarding time can be the same as the original signal transmission time, thereby realizing the fidelity of the long-term forwarding signal to the long-term original transmission signal.

[0153] The fifth logical principle is that, based on the logical points of the previous few items, a new conclusion can be drawn that the forwarding device can track the signal transmitted by the platform. If the platform transmits a short-time signal, the forwarding device will forward the short-time signal; conversely, if the platform transmits a long-time signal, the forwarding device will forward the long-time signal, that is, it can completely track the long and short-time patterns of the platform's transmission.

[0154] The significance of this regulation is that one of the existing achievements of this enterprise is that the long and short signals emitted by the platform can determine the two different states of the controlled object, such as the short signal is the on state and the long signal is the off state.

[0155] Therefore, the forwarding device must also correspond to the original signal emitted by the platform and forward it with fidelity to meet the requirements.

[0156] 5. Implementation and description of the forwarding track function; as shown in Figure 10.

[0157] Its significance is to realize the function of the enterprise's existing achievements.

[0158] Since the company's existing achievements can control up to 100 independent signals, the scope of use has been increased, including the control of track programs. Therefore, the forwarding device should be equipped with corresponding services.

[0159] The meaning of trajectory control is to detect or control 100 nodes of the control object. The logic of transmission and forwarding is to send instructions in sequence from the first control signal to the last control signal, so as to realize the trajectory transmission and forwarding of the control object. Therefore, the implementation method is:

[0160] The transmission system also includes a program control circuit unit, which includes a program connection element; each bit signal output end in the radio decoding integrated circuit is connected to the program connection element and connected to the reset input end of the previous time memory unit.

[0161] The principle of formation is that when the current signal comes, it is received and memorized, and the residual information of the previous memorized signal is synchronously eliminated. After the original signal ends, the current signal is forwarded again to avoid the interference caused by the residual previous signal being forwarded. The interval time of each original signal provides the time for each signal forwarding. Similarly, the third control signal is sent and forwarded until the last control signal is sent and forwarded, thus forming an orderly control of the trajectory of an object.

[0162] It is noted that, due to the flexibility of digital circuits, there may be special forms in which the program connectors are wires.

[0163] 6. Matching with other relevant achievements of the enterprise, generating three ways of forwarding enhancement and matching effect description:

[0164] (1) The company has already achieved the following results: First, the platform can use two emission states, short-term and long-term, to control the two states of an independent object, making the best use of the resources of each control signal. The forwarding device can cooperate accordingly, that is, generate corresponding forwarding:

[0165] Step 1 is to connect the radio decoding integrated circuit in the transmission system into a transient receiving mode. The characteristic of this connection is that the output signal of the radio decoding integrated circuit in the forwarding device will track the signal sent by the platform. That is, during the platform signal transmission process, there is always an output signal, and conversely, when the platform signal transmission ends, the radio decoding integrated circuit has no signal output.

[0166] Step 2 is that the forwarding device adopts the measures described in the forwarding control part; at the same time, the measures described in the long-term forwarding control part are adopted.

[0167] Step three is that the operation method is that the platform adopts a short emission control object as one state and a long emission control object as another state. The invention automatically cooperates with the corresponding forwarding.

[0168] The formation principles, such as basic forwarding circuit measures, forwarding control part measures, and long-term forwarding control part, are explained in three terms.

[0169] (2) The second transmission control method that the enterprise has achieved results is to use two separate signal instructions to realize two state controls of any object. Its advantage is that it does not use the long press and short press methods. The control platform can directly correspond to the buttons to suit the operating habits of a certain group of people. In this case, the forwarding device can still correspond to the forwarding enhancement.

[0170] Step 2 is that the forwarding device adopts basic forwarding circuit measures and forwarding control partial measures.

[0171] The third step is to divide the numerous signals into multiple groups, each group of two signals controls one object, one signal is in the on state, and the other is in the off state, and the forwarding device cooperates with the forwarding control part measures.

[0172] The formation principle, such as the description of the basic forwarding circuit and forwarding control part clauses.

[0173] (3) The enterprise has already achieved results. The third launch control method is, for example, to achieve the time sequence control and monitoring of many control points in the production line, or the control and monitoring of the motion trajectory of the flying object, etc. The forwarding device can cooperate with the corresponding forwarding.

[0174] Step 1 is to connect the radio receiver decoder integrated circuit in the transmission system to a transient output mode. It can also be connected to a locking mode.

[0175] The second step is to adopt the trajectory control clause five connection method.

[0176] Step three is that the operation method is to operate each control signal in sequence, such as operating the first control signal, the second control signal, etc. in sequence until the last control signal of the plurality of objects. The forwarding device automatically cooperates with the corresponding forwarding.

[0177] The formation principle is as described in the trajectory control clause five.

[0178] Various embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.

[0179] The terms used in this document are intended to best explain the principles of each embodiment rather than to limit the scope of the present invention. Terms with the same logical functions but different names also fall within the scope of protection of the present invention.
