The water level sensor is connected with the control circuit which is then connected with the radio frequency transmit-receive circuit. An antenna is connected on the radio frequency transmit-receive circuit. A serial port circuit is also connected on the control circuit. The water level sensor, the control circuit and the radio frequency transmit-receive circuit are respectively connected with a power supply for power supplying. The control circuit comprises an MSP430 processing chip and an AT24C02 storage chip which are used for data processing and storage. The radio frequency transmit-receive circuit comprises an NRF905 wireless radio frequency transmit-receive chip. The serial port circuit comprises a data interface which is mainly used for being connected with copying-reading equipment, write-in equipment or input equipment which is used for inputting of information set for operation of the control circuit and data uploading and downloading. The beneficial effects of the wireless water level detection device are that the wireless water level detection device has advantages of being high in practicality, wide in range of application, high in accuracy and great in reliability. Besides, the wireless water level detection device is convenient to install and use, low in cost and convenient for popularization and application.
Description
Technical field
The present invention relates to water level detecting technical field, specifically a kind of wireless water level pick-up unit.
Background technology
The application of water level detecting in the field such as plumbing and water conservancy is very common, such as, at rivers and lakes, pond, water tank, water tower, well etc.Some waterlevel data still taking artificial reading and record to record of water level detecting in the market, some is the automatic sensed water level signal of wire laying mode, but be away from the remote mountain villa of receiving center, rural area, rivers and creeks in a lot of use occasion, be inconvenient to setting of connecting up, greatly will increase difficulty of construction when connecting up, and cost is also high.
Summary of the invention
The object of the present invention is to provide a kind of easy to install, cost is low, accuracy rate is high wireless water level pick-up unit.
The technical solution adopted for the present invention to solve the technical problems is: wireless water level pick-up unit is primarily of level sensor, control circuit and RF transmit-receive circuit composition, level sensor is connected with control circuit, control circuit is connected with RF transmit-receive circuit again, RF transmit-receive circuit is connected to antenna, also be connected to serial port circuit on the control circuitry, described level sensor, control circuit and RF transmit-receive circuit are connected with power supply respectively powers, described control circuit comprises MSP430 process chip and AT24C02 storage chip, for process and the storage of data, described RF transmit-receive circuit comprises NRF905 less radio-frequency and to get into the frame of mind for work chip, can at 433MHz, the ISM frequency band work of 915MHz or 2450MHz, described serial port circuit comprises data-interface, be mainly used in connecting copy reading equipment, write device or input equipment, information set by running for input control circuit and data upload download etc., described power supply comprises dry cell.
The invention has the beneficial effects as follows, the present invention has practical, the advantage such as usable range is wide, accuracy rate is high, good reliability, and easy to install, and cost is low, easy to utilize.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
With regard to accompanying drawing 1, wireless water level pick-up unit of the present invention is described in detail below below.
As shown in Figure 1, wireless water level pick-up unit of the present invention is primarily of level sensor, control circuit and RF transmit-receive circuit composition, level sensor is connected with control circuit, control circuit is connected with RF transmit-receive circuit again, RF transmit-receive circuit is connected to antenna, also be connected to serial port circuit on the control circuitry, described level sensor, control circuit and RF transmit-receive circuit are connected with power supply respectively powers, described control circuit comprises MSP430 process chip and AT24C02 storage chip, for process and the storage of data, described RF transmit-receive circuit comprises NRF905 less radio-frequency and to get into the frame of mind for work chip, can at 433MHz, the ISM frequency band work of 915MHz or 2450MHz, described serial port circuit comprises data-interface, be mainly used in connecting copy reading equipment, write device or input equipment, information set by running for input control circuit and data upload download etc., described power supply comprises dry cell.
Principle of work of the present invention is, the water level signal of level sensor Test Field, and send the water level signal detected to control circuit, control circuit carries out recognition coding process to the received signal, and give corresponding time data signal, then, total data signal is packed and is sent to RF transmit-receive circuit in real time by control circuit together, in the frequency of operation segment limit of regulation, collection control receiving center is sent in time again by RF transmit-receive circuit and antenna, and wait the other side is received the confirmation signal beamed back by control circuit after being sent, fail to report to avoid loss of data, if when failing to obtain confirmation signal, control circuit will repeat to send set point number by RF transmit-receive circuit and antenna again, when not yet obtain confirmation signal then control circuit be automatically restored to normal condition and wait for wake up next time, when acquisition confirmation signal etc. then control circuit will proceed to park mode immediately, wait for and waking up next time, thus guarantee the accuracy that water level signal detects, ageing and security.
