Abstract

A remote controller using a radio paging network comprises an RF receiving circuit of two-stage frequency converting of a radio pager and a decoding circuit consisting of a single-chip microprocessor and a supporting chip of the microprocessor, wherein signals output from the microprocessor are processed and then supplied to a solid state relay which is provided with one or more ports for outputting the signals. By being provided with different interfaces for different power requirements, it is possible for the controller to control loads different in nature from AC/DC, high/low voltage etc., which will greatly improve the efficiency of a base station in an existing radio paging network without changing operating state of the same and saves investment and radio frequency resources. This invention is applicable to a variety of control conditions.

Description

Remote control using radio paging network

The invention relates to a device for remotely controlling remotely. Background technique

In some technical fields such as industry, agriculture, transportation, construction, etc., when long-distance operation control is required, in the past, they must be equipped with their own radio transmitting / receiving equipment. Not only the investment cost is large, but also Tight radio frequency resources. Summary of the Invention

The purpose of the present invention is to use the current public (or dedicated) radio paging network, modify the original radio paging BP machine, and make a remote control to solve the problems in the background technology.

The technical solution of the present invention is that it includes a radio frequency receiving circuit composed of a two-level variable frequency superheterodyne RF in a radio pager BP machine, and a single-chip microprocessor CPU supporting chip IC and a single-chip microprocessor CPU. Decoding circuit. The signal output from the single-chip microprocessor CPU is input to the solid-state relay after being processed by the processor, and then output from the solid-state relay port to control the load on or off.

The signal output from the LCD of the single-chip microprocessor CPU LCD is input via the BUS side of the processor composed of the interface chip single-chip microprocessor μP, and the switching signals are input to several corresponding I / O ports through several I / O ports. Solid state relay SSR—SSR _n and output; or combine the single-chip microprocessor CPU in the decoding circuit and the single-chip microprocessor μP in the interface circuit into a new microprocessor CPU / Δ, the signal is input through the CPU / Δ to switch The quantity signal is input to several corresponding solid state relays through several I / O ports

And output; or the signal output from the buzzer drive end, light drive end, and vibration motor drive end of the single-chip microprocessor CPU is processed by the processor composed of the trigger D and inverted, and then input to the solid-state relay SSR and output.

Compared with the background technology, the present invention has the beneficial effect that it can be equipped with output interfaces of different powers according to needs, and can control loads of different properties such as AC / DC, strong current / light current, etc., in the existing radio paging network technology Within the system, do not change the working status of the paging station (method, process

Confirm this Sequence), greatly improving the utilization of paging stations, saving investment costs and saving radio frequency resources. It is more suitable for occasions that require remote control but could not be used. Overview of the drawings

The signal transmitted by the host controller through a paging station using a local phone or a handheld phone (that is, Big Brother) is received by the wireless TX, as shown in Figure 1. After the signal is amplified and demodulated by the RF receiving circuit, it is input to the main The decoding circuit consists of a single-chip microprocessor CPU support chip IC and a single-chip microprocessor CPU. After decoding and the address code stored in the support chip IC to check the address (that is, the paging number), the signal is displayed on the LCD. The terminal LCD outputs to the BUS port of the single-chip microprocessor μP. The single-chip microprocessor μP processes the input signal through software and checks it with the user password and the on / off keyword password. number of I / O port output, a plurality of respective power control solid state relay device SSRr- SSR _n, turned on by the output terminal OUT control or disconnecting a respective load, to effect remote control operation. User password and on / off keyword password can be set and modified, which can be stored in the microcontroller chip or set off-chip by hardware. The power module AC / DC transforms, rectifies, and stabilizes the power supply voltage input from the IN terminal for the working power of each part of the remote control.

In order to reduce hardware circuits, reduce solder joints, and reduce power consumption, as shown in Figure 2, a single-chip microprocessor μP in the interface circuit of a single-chip microprocessor CPU in the decoding circuit is combined to develop a new micro-processing. Controller CPU / Δ, the function and working principle of the whole remote control are the same as the previous one, and will not be described again.

For example, the signal transmitted by the main controller via the internal phone or handheld phone through the paging station is received by the antenna TX, as shown in Figure 3, driven from the buzzer driver or light driver or vibration motor of the single-chip microprocessor CPU. The signal output from the terminal triggers the flip-flop of the trigger D, controls the solid state relay SSRi of the power device, and controls the load on or off via the output terminal OUT. The power module AC / DC transforms, rectifies, and stabilizes the power supply voltage input from the IN terminal for the working power of each part of the remote control.
