Abstract
A self-starting device of a wireless communication module for a data acquisition device comprises the data acquisition device, a wireless data transfer unit (DTU), a DTU working power supply and a drive circuit formed by a relay; the control terminal of the MCU (micro controller unit) of the data acquisition device is connected with the drive circuit; the negative terminal of the DTU working power supply is connected with the negative terminal of the wireless DTU; the positive terminal of the DTU working power supply is connected with one end of a normally closed contact terminal of the relay of the drive circuit; and the other end of the normally closed contact terminal is connected with the supply positive terminal of the wireless DTU. The utility model controls the on/off of the power supply of the DTU through the data acquisition device, thereby achieving veritable cold start.
Description
Technical field
The utility model relates to the electronics self-starting device, especially for carrying out data transmission between data collector and the wireless data transmission unit, when the two communication abnormality, detect primary power source automatically and turn-off and start-up operation, to realize the control device of wireless data transmission unit self-starting.
Background technology
The data of data collector transmit and transmit by wired or wireless mode, adopt wireless data to transmit and use the wireless data delivery module of being made up of GPRS mobile communication module and data communication processing module (DTU).This module is utilized GPRS (GPRS) technology of China Mobile, adopts point-to-point mode to realize remote data wireless transmission to the terminal that has communication function.And for the communication of adopting GPRS network to realize, itself can have dependence to network of relation, and from before related application, any wireless data transmission terminal can't guarantee that all long communication is normal.If when communication occurs when unusual, turn-off the DTU working power again the warm start mode of row startup cause the problem of data switch.
The utility model content
The purpose of this utility model provide a kind of when communication abnormality the effective self-starting device of the data collector wireless communication module that transmits of restore data.
This novel purpose is achieved in that a kind of self-starting device of data collector wireless communication module, comprise data collector, wireless data transmission unit DTU, the DTU working power, and the driving circuit of forming by relay, the MCU control end of data collector is connected with described driving circuit; The negative terminal of described DTU working power is connected with the negative terminal of described wireless data transmission unit DTU, the normally closed interlock that just is terminated at the driving circuit repeat circuit one end of DTU working power, this normally closed interlock other end is connected to the power supply anode of wireless data transmission unit DTU.
This novel beneficial effect is:
Data collector realizes that on hardware the mode of DTU cold restart provides the relay output contact of a special use, the normally closed output contact of positive termination data collector relay of wireless data transfer module power supply, the power positive end of another termination wireless data transfer module of the normally closed output contact of relay, be used to control the wireless data transfer module working power, the negative terminal of data transmission module power supply directly connects the power supply negative terminal of wireless data transfer module.
When data collector determines communication abnormality, just carry out and once turn-off and the closing relay output function, realize the startup of wireless data transfer module.
Therefore, adopting the cold start-up mode that DTU is carried out start-up function, is the effective means of recovering relevant GPRS device talk.
This is novel controls the power supply break-make of DTU by data collector, has realized real cold restart.
Description of drawings
Fig. 1 is this novel hardware structure diagram.
Embodiment
Fig. 1 illustrates, the transmission data terminal TX of the MCU of data collector (one chip microcomputer) is connected with the DTU corresponding interface respectively with reception data terminal RX and earth terminal G, the control end of MCU is connected with driving circuit, normally closed interlock one end of the relay of driving circuit is connected (power positive end with DTU power supply anode, be Vcc), the normally closed interlock other end is connected with the DTU working power is anodal, and DTU working power negative pole directly connects DTU earth terminal G.
Controlling mechanism:
1) data collector detects the time interval apart from normal communication last time according to the running parameter that the user is provided with on time;
2) in designated time intervals, data collector does not receive any once effective center communication command, just is identified as communication abnormality;
When 3) being judged as communication abnormality, data collector turn-offs the relevant relay 2 second time of output, to guarantee effective outage of wireless data transfer module;
4) reclose relay.
The course of work:
1) connect the line by drawing, connect the power supply of data collector and wireless data transfer module, according to the running parameter that user's request is provided with, promptly interval time was as 5 minutes.Connect data collector and wireless data transfer module and enter duty;
2) in 5 minute time interval of appointment, data collector does not receive any once effective center communication command, just is identified as communication abnormality;
When 3) being judged as communication abnormality, data collector activates relay, makes the normally closed contact of relay disconnect 2 second time, to guarantee effective outage of wireless data transfer module.
Claims (1)
1. the self-starting device of a data collector wireless communication module comprises, data collector, wireless data transmission unit DTU, the DTU working power, and by the driving circuit that relay is formed, it is characterized in that: the control end of the MCU of described data collector is connected with described driving circuit; The negative terminal of described DTU working power is connected with the negative terminal of described wireless data transmission unit DTU, the normally closed interlock that just is terminated at the driving circuit repeat circuit one end of DTU working power, this normally closed interlock other end is connected to the power supply anode of wireless data transmission unit DTU.
