The described collection based on integrated chip NRF24L01 and wireless sending module are multiple.
The described wireless receiving module be made up of integrated chip NETUSB24L01 is one.
Reception antenna is equipped with in the described collection based on integrated chip NRF24L01 and wireless sending module, the wireless receiving module that is made up of integrated chip NETUSB24L01.
Beneficial effect: owing to have employed technique scheme, the utility model compared with prior art has the following advantages:
What 1, adopt is all the MSP430 series monolithic of low-power consumption and the NRF24L01 wireless sending module of pole low-power consumption, carries and can be easily installed on equipment using battery as power supply, and can use for a long time; Voltage, the current signal of monitored equipment can be gathered very easily; The data of collection terminal collection are enable to transfer to the wireless receiving module of integrated chip NETUSB24L01 formation in real time, fast by wireless network, and be finally transferred to terminating machine and carry out Real-Time Monitoring management, without the need to carrying out loaded down with trivial details wiring, eliminate the restriction of data line to equipment under test, carry out the transmission of data quickly and easily;
2, cost-saving: the chip that the underground coal mine data transmission system based on the wireless communication technique of NRF24L01 module adopts and wireless transmission, receiver module are cheap, saved cost, avoid the waste of resource compared to traditional wiring loaded down with trivial details in a large number.
3, the engineering construction cycle is short: adopt wired mode, realize the interconnection between website, just must by the circuit of erection certain distance, and this just may need the engineering construction time of several months; Adopt the mode of the Wireless Data Transmission described in this patent, only need the antenna of the suitable height of erection, construction period only need in one month.By contrast, the mode of wireless telecommunications can set up communication link rapidly, greatly shortens construction period.
4, plant maintenance is simple: the maintenance of wired communication link need along the inspection of line, when breaking down, general being difficult to finds out trouble point in time, and adopts Wireless Data Transmission mode only need safeguard digital transmission module, reason can be found out fast when breaking down, recover circuit and normally run.And do not hinder the maintenance, repair etc. of monitored device.
