Along with the propelling of urbanization, city waterlogging problem highlights day by day.Run into rainstorm weather whenever summer, sewer water level has become an important indicator of early warning city waterlogging.
Also do not monitor in the market the monitoring transmission equipment of well lid sewer water level, main cause be exactly well lid be ferrous material, under the relatively serious and sewer of shielded signal, environment is severe, stabilization of equipment performance does not reach the standard of long-term use.The general obstructed civil power in well lid below in addition, solar charging panel is laid nowhere, and power problems has also become to hinder the factor of well lid level measuring.
Utility model content
The purpose of this utility model is to provide a kind of level gauging telemetering terminal, and measurement accuracy is high, and stabilization of equipment performance is good.
For solving the problems of the technologies described above, the utility model provides a kind of level gauging telemetering terminal of sewer liquid level remote supervision system, this system comprises central station and level gauging telemetering terminal, level gauging telemetering terminal comprises central control unit, also comprise with central control unit the ultrasonic measurement unit being electrically connected, sewer liquid level is measured and the wireless communication unit being electrically connected with central control unit, described wireless communication unit comprises the planar antennas that is fixedly installed on well lid top and the DTU that is integrated in central control unit.
Further, also comprise with central control unit the temperature sensor that is electrically connected, temperature in sewer is measured.
Further, also comprise the acceleration transducer being electrically connected with central control unit.
Further, also comprise the FLASH storer for storing data.
Further, described wireless communication unit comprises GRPS/ note transtation mission circuit.
Adopt technique scheme, the beneficial effects of the utility model are: level gauging telemetering terminal of the present utility model, utilize ultrasonic measurement unit to carry out non-cpntact measurement to the liquid level in sewer, can avoid the impact of the foreign material in sewer, than adopting float-type, the measuring units such as pressure-resistance type liquid level transmitters have higher precision, stabilization of equipment performance is better, adopt wireless communication unit to carry out wireless connections with central station, networking is convenient, small investment, employing is fixedly installed on the planar antennas of well lid top, can avoid the block shielding of well lid to signal on the one hand, ensure the completeness and efficiency of signal, can ensure that on the other hand antenna and well lid have larger fitting area, load-bearing capacity is high, make antenna be not easy to be damaged by pressure by vehicle, can not affect the normal current of vehicle simultaneously,
The temperature of set temperature sensor in can Real-Time Monitoring sewer, thus automatically liquid level is compensated to calculating, can improve liquid level measurement precision.
The acceleration transducer being electrically connected with central control unit is set, can monitor the acceleration situation of this terminating machine, make this equipment there is anti-theft feature, this equipment can be fixed on the borehole wall or well lid below, in the time that it is stolen, the acceleration change situation that acceleration transducer is monitored is sent to central control unit, and central control unit can send warning by wireless communication unit.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of level gauging telemetering terminal of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Figure 1 shows that the disclosed a kind of structure of sewer liquid level being carried out to the level gauging telemetering terminal of remote monitoring of the utility model, this system comprises central station and level gauging telemetering terminal, and level gauging telemetering terminal comprises a central control unit, a ultrasonic measurement unit and a wireless communication unit.Central control unit adopts the ARM process chip of low-power consumption, has intelligent park mode, at ordinary times in dormant state, in the time of work, just can wake up from dormant state, therefore there is longer stand-by time, can for a long time non-maintaining normal operation, it adopts powered battery.
Ultrasonic measurement unit is electrically connected with central control unit, it comprises that ultrasound wave sends and receiving circuit, ultrasound wave that ultrasonic measurement unit sends reflects after arriving the liquid level of sewer, received circuit reception, after signal is processed by voltage form by central control unit processing.Hyperacoustic run duration is directly proportional to distance, is transmitted and received the time and carries out timing hyperacoustic by central control unit, can try to achieve water level by the velocity of sound and institute's travel-time.This level gauging telemetering terminal also comprises with central control unit the temperature sensor that is electrically connected, temperature in sewer is measured.With carrying out temperature compensation calculating to liquid level after temperature sensor, obtain more accurate acoustic velocity value, thereby improve measuring accuracy.
Wireless communication unit is electrically connected with central control unit, and it comprises GRPS/ note transtation mission circuit and is fixedly installed on the planar antennas of well lid top.Adopt GRPS/ note transtation mission circuit can utilize public communication network to communicate, saved networking investment, adopt planar antenna also to ensure the reliability of signal.
This level gauging telemetering terminal also comprises the FLASH storer for storing data and the acceleration transducer being electrically connected with central control unit.FLASH storer uses a road SPI interface, and the pin of having saved processor takies has also simplified circuit design, the permanent power down storage of FLASH storer, the integrality of guarantee data.
Acceleration transducer is set can be for antitheft.Dormant state in the time of accident water gaging position, acceleration transducer is in running order, and the acceleration of moment monitoring equipment sends alarm signal when equipment Acceleration changes in amplitude exceedes early warning value alarm device to central station, plays so antitheft effect.If this equipment body is installed on well lid, can also prevent that well lid is stolen.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
