Abstract

The utility model relates to a double-network on-line long-distance monitoring controller. The utility model comprises a networking monitor terminal composed of a single chip computer and a network communication program and a modem which are arranged in the single chip computer. The output end of the monitor terminal is respectively connected with a communication device of a public telephone switched network and a wireless communication network. The monitoring networks of a computer and a mobile phone can be directly formed by a wireless type and a wired type. The utility model has the advantage that the combination of the wireless type and the wired type is used for conducting network communication to enable the reliability and the adaptability of the communication of the device to be higher than the communication mode of a single network. When two networks simultaneously work, the advantages of CSM and PSTN are mutually compensated to enable the communication function to be more abundant. When an exclusively used station is not stable, the GSM or the GPRS can be started at any time to conduct the network communication to further guarantee the reliability of the communication.

Description

The online long-distance monitorng device of two nets

Affiliated field:

The utility model belongs to a kind of automatic monitoring device, the online long-distance monitorng device of particularly a kind of two nets.

Background technology:

At present domestic and international various industrial monitor terminal RTU, function singleness aspect remote network communication, adaptability is relatively poor.

Summary of the invention:

The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of two nets online long-distance monitorng device, and this device strengthens terminal adaptability and reliability greatly.

The technical solution of the utility model is: the online long-distance monitorng device of a kind of two nets, comprise by single-chip microcomputer, be contained in the networked control terminal that network communication program in the single-chip microcomputer and modulator-demodulator are formed, it is characterized in that: connected the communicator of cordless communication network and public switched telephone network (PSTN) respectively at the output of monitor terminal, can directly form computer and monitoring mobile phone network by wireless and wired mode.

Above-mentioned cordless communication network can adopt mobile radio communication GSM

Above-mentioned cordless communication network can adopt block exchange mode GPRS.

The utility model has the advantages that: carry out network service by wireless and wired combination, make communication adaptability, the reliability of this device be much higher than single communication mode of netting.When two kinds of networks were worked simultaneously, GSM and PSTN had complementary advantages, and make communication function abundanter.When private station is unstable, can start GSM or GPRS at any time and carry out network service, further guaranteed the reliability of communication.

Fig. 2 is a main program block diagram of the present utility model

Fig. 3 is a network communication program block diagram of the present utility model

Embodiment:

As shown in Figure 1: the online long-distance monitorng device of a kind of two nets, comprise by single-chip microcomputer, be contained in the networked control terminal that network communication program in the single-chip microcomputer and modulator-demodulator are formed, it is characterized in that: connected the communicator of cordless communication network and public switched telephone network (PSTN) respectively at the output of monitor terminal, can be directly formed computer with the PSTN mode and be connected with the monitoring mobile phone network by wireless.Above-mentioned cordless communication network can adopt mobile radio communication GSM, also can adopt block exchange mode GPRS.

Shown in Fig. 2,3: the utility model has four kinds of operating states.

1, init state

At first carry out function initialization and self check after the start, to LCD interface, keystroke interface and signaling interface carry out related setting, and modulator-demodulator is carried out self check, just it are carried out AT order setting if modulator-demodulator has been installed, and make it enter operating state.

2, detect show state

Initialization later on device enters this state, in order eight channel input signals is switched and detects.The detection data are delivered to the memory block by integration and range conversion and are shown.

3, the human-computer dialogue state enters this state when user of service's operation push-button, and the parameter that can import and revise has instrument coefficient, pipe diameter, signal zero, host computer telephone number, meter number, date, time, filter factor etc.

4, network service state

PSTN then enters this state as bell signal or timed sending time, and main frame carries out connected network communication by modulator-demodulator and computer.At first analyze receiving character.If the compunication character then enters communications status, otherwise the Host Command modulator-demodulator turns off immediately, withdrawing from communication and entering armed state.After entering communications status, instrument upwards transmits data and parameter according to computer command, transmitting finishes receive the machine order after, turn off modulator-demodulator and enter armed state.

GSM can the timed sending data, also can query call, and whom who recalls, i.e. and available computers sampling also can be adopted the mobile phone sampling, and is very convenient.

Claims

1, the online long-distance monitorng device of a kind of two nets, comprise by single-chip microcomputer, be contained in the networked control terminal that network communication program in the single-chip microcomputer and modulator-demodulator are formed, it is characterized in that: connected the communicator of cordless communication network and public switched telephone network (PSTN) respectively at the output of monitor terminal, can directly form computer and monitoring mobile phone network by wireless and wired mode.

2, the online long-distance monitorng device of two nets according to claim 1, it is characterized in that: above-mentioned cordless communication network can adopt mobile radio communication GSM

The online long-distance monitorng device of 3 two nets according to claim 1, it is characterized in that: above-mentioned cordless communication network can adopt block exchange mode GPRS.
