Embodiment
Contrast accompanying drawing 1, its structure comprises remote control tripping operation control loop, break detection circuit, specially become acquisition terminal core processing unit, telecommunication module, user's main station system, wherein, the TXD0 end that specially becomes acquisition terminal core processing unit is held and is joined with the TXD of telecommunication module, the RXD0 end that specially becomes acquisition terminal core processing unit is held and is joined with the RXD of telecommunication module, the UTXD1 end that specially becomes acquisition terminal core processing unit is held and is joined with the DCE_TXD of break detection circuit, the URXD1 end that specially becomes acquisition terminal core processing unit is held and is joined with the DXE_RXD of break detection circuit, the signal output part of the DXJC signal input part of break detection circuit and remote control tripping operation control loop joins, telecommunication module is connected with user's main station system by GPRS wireless network.
Described core processing module: be mainly made up of primary processor, storer and memory chip etc., primary processor is mainly responsible for the processing of data, adopts 32 ARM9 processors, and performance is up to 200 MIPS.
Described break detection circuit: adopt the optocoupler TLP184 of Toshiba, its feature: isolation voltage is high, transfer ratio 50%-400%.
Described telecommunication module: support multiple communication modes, as 230M private network, GPRS, CDMA etc.Taking GPRS communication module as example, this telecommunication module now adopts the M72 module of Yi Yuan company, this module is two frequency band GSMs/GPRS wireless module of a technical grade, GPRS communication module and terminal primary processor carry out data transmission by UART interface, GPRS communication module correctly fixes up an aerial wire and available SIM card, after the normal work of energising, can carry out being connected to corresponding network after relative parameters setting, can carry out acceptance and the transmission of data by network.
Described user's main station system: user's main station system is mainly made up of communication interface machine, acquisition server, database server, application server etc.
Described remote control tripping operation control loop: depending on field condition.
As shown in Figure 2, its ultimate principle is by testing circuit and at the normally opened contact of Remote Control Interface (in Fig. 2 public with often open two contact places), and when remote control is during in non-action state, optocoupler D1 is connected in control loop like this.And R1, R 2, R3, these 5 resistance of R4, R5 in Fig. 2 play metering function, can protect that optocoupler is not breakdown can prevent again trip circuit misoperation.In order to adapt to on-the-spot relay and loop situation, the model that we select optocoupler D1 is TLP184, and this is a kind of two-way optocoupler, thus no matter on-the-spot use exchange or direct current we the normal signal in loop can be detected.And signal DXJC in Fig. 2 is connected to our CPU, the signal that CPU accepts by analysis judges whether remote control circuit occurs broken string.Wherein the processing unit of terminal both can be having detected that active reporting main station system was to notify user when abnormal, and user also can inquire about field condition by order.
