Description
Technical field
The utility model relates to a kind of remote monitor device, especially relates to a kind of remote monitor device for grouping data transfer water supply pipe network pump station that is used for.
Background technology
Existing water supply network remote measurement and control dispatching system adopts digital radio data transmission radio station (abbreviation data radio station) communication modes, each pipe network detects website 1 road analog data (pressure of pipe network) only is provided, host computer is programmed with VB, and the data acquisition of man-to-man " poll " formula is carried out to all websites (for example 42 websites) in the radio station of control center's end in official hour.
Data radio station is to adopt digital signal processing and digital modulation and demodulation, the wireless data transmission radio station with functions such as forward error correction and balanced soft-decisions.Data radio station provides transparent RS232 interface, and transfer rate reaches 19.2Kbps, and transmitting-receiving has indication and functions such as Bit Error Code Statistics, state alarm and network management such as field intensity, temperature and voltage less than 10ms switching time.
The shortcoming that existing water supply network remote measurement and control dispatching system exists mainly is:
1. detect the limited amount of website.The data transmission network that data radio station is formed is monopolized a frequency resource, simultaneously an equipment sending data can only be arranged on same frequency.The polling mode data query is adopted to the allocation of communications mode of far-end multiple spot in general employing center, and polling cycle and radio station quantity have substantial connection.Suppose that website of visit needs 0.5s, poll wait timeout time set is 3s, there are 100 terminals in system, polling cycle is 0.5 * 100=50s under all terminal works normal conditions so, if a station terminal is arranged owing to reasons such as equipment failure, frequency interferences cause bust this, system will wait for 3s in this terminal, and the long period of poll may be 3 * 100=300s.The poll pattern of data radio station and coverage have determined the capacity of network that certain limit is arranged, and the quantity that detects website can not increase endlessly.
2. plant capacity is unfavorable for greatly installing in the by-place.According to State Radio Regulatory Commission's frequency planning, with the frequency range of 223.025～235.000MHz as professional use such as remote measurement, remote control and data transmission.Be used for closely (in the 1000m) operation time≤0.5W, when being arranged on city and suburb nearby ,≤5W; When being arranged on the outer suburbs and field ,≤25W.Data radio station is subjected to transmission power limit, and the transmission range maximum has only tens of kilometers, and over distance sends needs high-power emission, and large power supply need be provided.The emissive power of data radio station generally is 25W in industrial applicability, and this characteristic has determined the application of data radio station can only be limited in the certain areal extent, is unfavorable for installing in the by-place.
3. build and the operating cost height.The construction cost of data radio station except the purchase cost of data radio station, also needs to comprise base station construction costs such as setting up control tower and antenna.Especially for the area that belongs to the hills landforms, and also there is very big influence in high height above sea level place to the reflection and the refraction of electric wave, must be at high height above sea level local construction relay station.The hills landforms also make the some areas that cover of radiowave produce the dead angle.If transmission range is long, then signal is decayed easily, carry out signal relay transmission by each relay station, and long Distance Transmission must be built more base station, and transmission range is far away more, and the base station construction cost is just big more.Data radio station is built voluntarily by Subscriber Unit, need not to pay communication cost, but frequency occupancy and also be a no small expense to the maintenance cost of radio station equipment, radio station quantity is few more, and unit cost is just high more.
The data radio station construction is influenced greatly by urban construction, the digital transmitting network of having built is stopped by high buildings and large mansions newly-increased in the city probably, housing-group also has very big influence to the reflection and the refraction of electric wave, self-built radio station data transmission network must constantly be adjusted network at situation about occurring in the urban construction, comprise the portable antenna position and increase antenna height etc., may also will adjust frequency in case of necessity according to the requirement of radio regulatory organization.These occupy very big share in later stage operating cost, and do not know that forever next step has the work and the spending of which needs.Therefore for belonging to hills landforms and high altitude localities, the addressing that detects website is particularly inconvenient, and equipment installation and maintenance intensity also will inevitably be very big.
4. the data parameters of Cai Jiing is few.Existing systems only provides the data (ductwork pressure) of 1 tunnel analog quantity, can not embody on-the-spot equipment operation situation preferably.
5. have a strong impact on data transmission when being interfered.In an application system, two or many data radio station networkings, each data network takies a frequency, when this frequency is interfered, will have a strong impact on data transmission.
Existing sub-district pumping station operation monitoring system is to adopt the modulator-demodular unit of main center P C machine to be connected by dialing with the modulator-demodular unit of each pumping plant PC, therefore has following shortcoming.
1) can't react on-the-spot ruuning situation in time.Existing systems is carried out data acquisition by the manual dial to each pumping plant.When you need understand the situation of certain pumping plant, just by dialing the phone of this pumping plant, wait the both sides phones to be communicated with after, on-the-spot data pass to the pumping plant center by telephone network.Can only get in touch with a pumping plant at every turn.That is to say, understand the situation of next pumping plant, must disconnect this dialing, and then dial the phone of next pumping plant.After each phone was communicated with, to data transmission is finished, each pumping plant needed 20～30min.That is to say, need 3.5h, then can only carry out 6～8 times visit to 7 pumping plants in one day if the operation of 7 pumping plants need have been understood.After the pumping plant website increased, the problem that can't in time react on-the-spot ruuning situation was just more outstanding.
2) operator on duty's labour intensity is big.From the above, each pumping plant need just can be known the pumping plant situation with the manual dial, if it is all unclear with regard to what situation not carry out the manual dial, will wait for also after the connection that 20～30min just can obtain on-the-spot situation.Therefore need the operator on duty ceaselessly to go to dial and could understand the ruuning situation of each pumping plant, operator on duty's labour intensity is big, and spirit is in the high-pressure state, makes the operator on duty tired out easily.
3) operation and managerial cost height.Adopt phone dialing mode, require main website that a phone is installed, each pumping plant also must be installed a phone.Every phone is except the base expense of each, and when you dialled understanding pumping plant situation, need to pay the telephonic communication expense that is communicated to when disconnecting after the connection (approximately was 20～30min at every turn; Every day 6～8 times approximately is 160～200min; 180～240 times every month approximately is 4800～6000min, and the telephone charge of every month each pumping plant needs 1000～1500 yuan).Therefore, adopt the operation and the managerial cost of phone dialing mode not low.
At the problem of above-mentioned existence, the relevant report of more existing improvement projects.(Han Xiaoping such as Han Xiaoping, Shao Hongqiang, Li Baiguo, the application of GPRS technology in power remote meter reading system, electronic surveying and instrument journal, 2005,4) a kind of power remote meter reading system based on the GPRS mechanics of communication has been proposed, the GPRS terminal is got involved Internet via GPRS net,, realize terminal and client's message exchange by the communications protocol between the communication center server and client-server among the Internet is set.(Xia Kefen such as summer coffin, ecliptic is flat, based on the application of the wireless long-distance meter-reading system of GPRS technology at power department, for electricity consumption, 2005,4), propose and designed the structure and the implementation of system at the requirement of wireless kilowatt meter reading-out system to data transmission credibility and real-time, this system adopts MCU, GPRS wireless communication module, ICP/IP protocol processing module and GPRS network, realizes the enforcement collection and the transmission of data.
