Abstract

PURPOSE:To maintain an operation in a noisy state by writing a transmitted data in a memory temporarily, and furthermore storing only a normal in a controlling memory. CONSTITUTION:When a signals is received, decoding is executed by a microcomputer 16. Decoded signals of ''1'' and ''0'' are stored in a receiving memory. Subsequently, whether contents of the receiving memory are normal or not is checked. As a result, a normal signal among the signals is stored in an operation controlling memory and a signal which is influenced by a noise to be abnormal is not stored. Accordingly, the part influenced by a noise is controlled by the previous data to prevent its abnormal operation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reception control method for a remote control device that controls the operation of a breaking machine at a remote location.

Conventionally, in transmitting devices for remote control devices,
In order to remotely control multiple control contents of the machine, there are multiple selection switches for each control contents, and after the user selects and operates the appropriate mode, the transmitter operates the switch to start transmission. A device (hereinafter referred to as a preset type transmitting device) has been developed that receives the tl and sequentially converts each control content into a signal and transmits it using various propagation signals such as wired or wireless. Therefore, it is possible to provide the convenience of being able to confirm at the time of transmission or after transmission at the transmitting device. This can be seen, for example, in transmitting devices of wireless remote control devices that use light to remotely control air conditioners such as room coolers. However, conventional reception control devices simply receive received signals and remotely control the operation or mode of the controlled device, and what is more, if the control signal becomes unreceivable due to noise etc. during propagation, In this case, all the contents of the - times of transmission were canceled, and in this case, the controlled machine could not be remotely mounted. For this reason, remote control has not been practical in situations where the transmission/reception distance is relatively long or there is a lot of noise. Conventionally, when doing this, it was necessary to reduce the number of transmissions and to control reception on the receiving side to reduce the probability that noise would enter the transmission and reception. This requires the user to perform complicated transmission operations, which is inconvenient. In addition, when the power of the receiving device is turned off and on, the controlled device does not start moving, especially if the above-mentioned one-time transmission content is canceled, and in the method described later, all modes are operated completely. Due to this necessity, many switch operations were required, making it extremely complicated.

The present invention has been made to eliminate all of the above-mentioned drawbacks of the conventional technology, and allows a preset type transmitting device with poor operability to be used as a transmitting device. The part is capable of remote control with a function to control the operation of the controlled machine according to the content received normally last time, and is designed to prevent malfunctions.
If only the operating information can be received from the transmitted signal from time to time when the receiving device starts up, other modes will be automatically determined within an appropriate range, and all remote control such as operating the controlled machine for the time being can be performed, which is useful for practical purposes. The overall purpose of the present invention is to provide a remote reception control method.

Hereinafter, one embodiment of the present invention will be described with reference to all the drawings.

In one embodiment of the present invention, the operation or stopping of the controlled machine is set as one control content (■), and the control content of devices B and C in the controlled machine is set to three modes: (0), (2) or (3) respectively. , control details are marked ■ and ◎, respectively.

FIG. 1 shows a prisé-node type transmitter according to an embodiment of the present invention, where 1 is the main body of the transmitter, 2 is an operation switch that determines the control contents, and 3 and 4 are respectively Operation switch 6 for determining control details ■ and O
indicates a switch to start transmission. Here, for example, the operation switch 2 is turned to set the control content ■ to operation, the operation switch 3 is turned to set the control content ■ to mode ■, and the operation switch 4 is turned to set the control content ◎ to mode ■. Then, by operating the transmission switch 6, control contents ◎ to ◎ are sequentially transmitted as 6 transmission signals. The timing chart of this transmission signal is shown in Figure 2. As each transmission data, a signal that determines one control content is transmitted for a certain period of time T.
Operation data 6 is sent as control content, data 7 as mode ■-■ is sent as control content, and data 8 as mode data ■-■ is sent as control content @. There is. Here, the transmission switch 6 in FIG. 1 may also serve as the operation switch 2. In this case, the operation data 6 in FIG. It is also easy to make it mean a stop. Note that the configuration and detailed operation of the transmitting device that performs such transmission, the transmitted signal itself, and the propagation method are not the gist of the present invention, so illustrations and explanations will be omitted.

Now, 1. Regarding the receiving device which is the king of the present invention,
This will be explained in detail below using FIGS. 3 to 6. Note that the received signal is the transmitted signal shown in FIG. 2 mentioned above, and since the transmission and reception in other various modes are the same, their explanation will be omitted.

FIG. 3 shows a block diagram of a receiving device in an embodiment of the present invention, in which 9 is a reception input means, 1o is a data memory,
11 is a controller, 12 is a control (goods) means, 13.14
Reference numeral 15 indicates a controlled device, and 15 indicates various setting input means. Here, the aforementioned transmission signal is received by the reception input means 9, converted into a signal that can be received and processed by the controller 11, and sent to the controller 11, and the controller 11 receives this, In predetermined cases, various data are exchanged with the data memory 10, and output is output to the side tilting means 12 based on the results of a predetermined judgment procedure. In response to this, the side (goods) means 12 controls the controlled devices 13 and 14 or destroys them.
It drives the power supply for the main body of the Hawari machine, which has devices 13 and 14. The setting input means 16 performs various initial settings and notifies the controller 11 of the settings.

A detailed explanation of the operation will be given later. Hereinafter, the same symbols will be used for the same parts, and the explanation will be omitted, and the same will apply to parts unrelated to the present invention.

The transmission signal shown in FIG. 2 will be explained in detail below using FIGS. 4 to 6 as an example.

FIG. 4 is an electronic circuit diagram of a receiving device according to an embodiment of the present invention, and 16 is a microcomputer (hereinafter referred to as
31 is the power supply for the main body of the Hawari machine. This microcomputer 16 has ROM and RAM,
It is composed of various input/output ports, etc., and receives the received signal in a decodable form from the receiving input means 9 from the iNT input terminal via the resistor R1, and sends an appropriate output to each of EO to G2 through a predetermined procedure. The control means 12 is controlled through the output port. Further, the setting input means 1
6, the initial set value for each mode is given from each input port of BO-C1, and is used as the initial value in this procedure. The auxiliary means 12 is composed of inverters 17 to 23 and relays 24 to 3o, and receives the output from the microcomputer 16 and drives the corresponding relays, thereby stopping the operation of the breaking control machine and stopping the operation of the breaking control machine body. Control equipment 13.1
We are implementing the 4 system (goods). The setting input means 15 includes a jumper wire 11. J2 and resistors R2 to R6, and this jumper wire T1. By appropriately selecting J2, a predetermined initial set value can be set for each mode.
It is output to the microcomputer 16. Note that, for example, when the received transmission signal is a wireless signal using an original,

It is composed of a PIN diode, a wave detector, a tuner, a waveform shaper, etc., and this configuration is almost uniquely determined by the transmission form, as is well known. However, the detailed configuration and explanation thereof are the same as those of the microcomputer 16, and the power supply circuit of the receiver is not the gist of the present invention and can be easily accomplished using well-known techniques, so they are not shown and the explanation will be omitted.

Next, the operation will be explained using the flowcharts of FIGS. 5 and 6. Both figures show the predetermined procedures carried out in the microcomputer 16 and briefly explain the receiving side method of the remote sterilization device of the present invention.

1. At the beginning of its operation, the microcomputer 16 first clears all data memories and waits for input from the transmitter. At the same time, input is made from the setting input means 15 through the B port and C port, the state of the jumper wire is read, the setting is set as shown in Table 1, and the contents are decoded based on this. Control contents ■ and control contents ◎ are stored in memory in advance. These various types of memory actually mean built-in RAM at predetermined locations.

Table 1 When a transmitted signal is received there, the signal is transmitted to the iNT.
The signal is input from the input terminal, and in this embodiment is processed as interwoven, and the received signal is decoded using a predetermined method. For example, if "o", 1" is sent as a signal length, all you need to do is measure it, and the configuration for this is almost sufficient with the microcontroller, and well-known technology can be used. Since this is easily possible and is not the gist of the present invention, illustrations and explanations will be omitted.The deciphered results are as follows:
Stored in reception memory. During the period when no received signal is received, the contents of the received memory are decoded and first it is determined whether the signal is normal or not. If the result is a normal signal, it is classified, stored in various memories, and its contents are updated. At this time, if you set the contents of the driving memory to be processed only when driving, except for the driving side (goods) signals,
This is useful in preventing unnecessary changes and malfunctions when the Hawari machine is stopped, and is also used in the Honten example. After processing these received signals, clear the contents of the reception memory, read out the contents of the memory for operation memory, control contents ■, and control contents O in sequence and send them to each destination port E, F, and G. Output as content. In response to this output, the separate display means 12 operates or stops the controlled machine body or changes the mode of the breaking equipment 13, 14. Here, the operation and stopping of the above-mentioned side (corporate) contents ■ are realized by turning on and off the relay 24 by turning on and off the E○ output port, and the aforementioned control contents ■ and ◎ ■ to ■ are , respectively, by turning on and off the corresponding output capacitors) FO-G2, and as a result, it comes to be controlled by the settings of each operation switch of the transmitting device. By repeating the above series of processing steps, the desired remote side (2) was achieved.

If the same received signals are obtained using the transmitted data shown in Figure 2, and all the signals are normal, then
First, a first operation signal is input to the iNT input terminal,
As a result, the operation signal is set in the reception memory, and since it is a normal signal, the same content is set in the operation memory. Afterwards, the reception memory is cleared, and the operation signal is taken out from the operation memory and sent to the Eo output terminal.
In response to this, the side tilting means 12 supplies power to the main body of the controlled machine and starts operation.

Suddenly, the next ■-■ signal is received, input again from the iNT terminal, and this time the ■-■ signal is set in the reception memory. Since this is also a normal signal, and because the vehicle is in operation, the same signal is set in the memory for control details (■). As before, the reception memory is cleared, and this time the control contents■
By using the same signal read from the memory, both the Fo and Fl output terminals are reset, and the F2 terminal is set, the controlled device 13 is fixed in mode (2).

The next ◎−■ signal is processed in the same way as above,
The breaking device 14 is in mode ■. However,
If each signal cannot be received normally due to disturbance such as noise, each signal is ignored, the contents of each memory are retained, and no malfunction occurs. Now, if only the operating signal can be normally received during the first reception after the receiving device is started up, the setting input means 15 is set in advance in accordance with the contents of each data memory that has been reset 7). So, for the time being, the Hawari (goods) machine starts operating.

In one embodiment of the present invention, the received signal from the reception input means 9 is input to the iNT4 terminal of the microcomputer 16 and is subjected to interoperable processing, but other two-wire or three-wire signals may be used. - Any other method that can be incorporated by a microcomputer, such as a handshake method, may be used, or an LSI having the above-mentioned functions may be used instead of a microcomputer. In addition, in the setting input means, if you do not want to make such a selection in advance, you can incorporate the setting into the program and eliminate various parts such as external jumper wires, and if you want to make selections relatively freely. , the jumper wire ■1. ■You can use point 2 as a switch. Also, of course, the data memory should be able to be backed up, and the receiving device should be turned on/off.
It is also easy to eliminate the harmful effects of turning off the power. Of course, it is acceptable even if the content of each side does not directly output to the output port, and the content of the transmitting device and the transmission propagation format (light, sound,
It may be wired (using radio waves or the like) or wireless (using serial or parallel signals), and any of the above cases does not depart from the gist of the present invention.

As detailed above, according to the reception method of the present invention, it can be realized with a simple configuration of a reception input means, a data memory, a setting input means, a controller, and a control means, and is easy to operate. It is possible to use an excellent preset type transmitter, and not only does it have many advantages in actual use, but it also has the ability to prevent erroneous operation, and is effective even if 2 is detected at startup. practicality,
It can be realized with great flexibility and is extremely useful and useful especially for remote parties between relatively distant locations or under noisy conditions. Moreover, since a preset type can be used for the transmitter, the user can check each transmission mode at a glance during or after transmission, which is extremely convenient even in underground operations.
