Please refer to fig. 1, the utility model provides a wireless liquid level locator 100 that non-contact liquid level detected and wireless positioning phase and fuse, including the liquid level sensing module 1 that carries out liquid level data acquisition with liquid level sensing module 1 communication connection and with 2 wireless connection's of external base station wireless location module 3 and give liquid level sensing module 1 with power module 4 of the power supply of wireless location module 3.

The liquid level sensing module 1 comprises a PCB10 and a liquid level data acquisition chip 11, wherein the PCB10 comprises a data acquisition surface and a data component surface used for installing the liquid level data acquisition chip. Specifically, the data acquisition surface is a whole piece of non-GND PCB copper-clad. The mode of PCB copper-clad direct induction is adopted, and compared with the traditional metal sheet data acquisition mode, the detection is more direct and accurate.

It is further explained that, the liquid level sensing module 1 is in the embodiment of the utility model discloses an install in chemical bucket 7, this liquid level sensing module 1's sensing part laminating is on chemical bucket 7's the bucket wall, and other parts are installed in the barrel head of chemical bucket.

Further, the working principle of the liquid level sensing module 1 is as follows: the precondition for the liquid in the chemical barrel is the presence of electrons, and when the position surface of the PCB10 in the liquid level sensing module 1 in the chemical barrel 7 is empty (empty state), the liquid level data acquisition chip 11 acquires the state as a reference, and then provides a state information (assumed to be low level) through the I/O port. When liquid exists in the chemical bucket, because electrons in the liquid are relatively more, the liquid level data acquisition chip 11 acquires the electronic state which is more at the moment, because the electronic state is different from the previous state and has a larger difference, the output of the 1/O port is opposite to the state information (high level) in the empty state at the moment, and then the information receiving device 31 is informed. The summary shows that the state change information from the liquid state to the liquid-free state in the chemical bucket 7 is collected and then is sent to the monitoring platform 5 through the wireless positioning module 3. The manufacturer is notified to process the chemical bucket 7.

The wireless positioning module 3 comprises an information receiving device 31 in communication connection with the liquid level data acquisition chip 11, a positioning device 32 connected with the information receiving device 31, and an antenna 33 connected with the positioning device 32, and the wireless positioning module 3 is in wireless connection with the external base station 2 through the antenna 33.

Specifically, the information receiving device 31 is a bluetooth module or an MCU. In order to save cost, the Bluetooth module can be preferably adopted, and the Bluetooth module is used for power supply dormancy management and signal receiving control management. The main functions of the information receiving device 31 are power management, sleep and wake-up functions, and signal collection and transmission of the liquid level sensing module 1 to the positioning device 32.

The positioning device 32 is 4G-CAT1 or NB-LOT, and is mainly used for uploading position positioning and status information to a telecommunication, a communication or a mobile platform. 4G-CAT1 is more costly, but because there are more 4G base stations and strong signals available in remote areas. The NB-LOT scheme is less costly, but since NB base stations are mainly concentrated in some cities, there are fewer base stations in remote areas, mainly for areas with stronger signals. And may be selected according to circumstances.

The utility model provides a positioner 32's locate function is applicable to non-shielded indoor and outdoor scene. The method mainly adopts a base station positioning mode. The locator of GPS + big dipper positioning mode is not suitable for being used in indoor scene, and the signal is weak or none.

Antenna 33 is wrapped up by the plastic casing, prevents to keep apart antenna signal, and the effect is transmission and receiving high frequency signal, sends the state information of wireless location module 3 to outside basic station 2, and outside basic station 2 passes to information and receives monitoring platform 5. Or sending an instruction to the external base station 2 through the monitoring platform 5, and then receiving information sent by the external base station 2 through the antenna 33 of the wireless positioning module 3.

The wireless location module 3 further comprises a communication card 34 connected with the location device 32, wherein the communication card 34 provides ID identity information, and the identity information interacted with the external base station 2 is verified to ensure uniqueness.

Power module 4 includes battery 41, with power conversion module 42 that battery 41 is connected and with power control module 43 that power conversion module 42 is connected, power module 4 passes through power control module 43 is right liquid level sensing module 1 with wireless locating module 3's power supply is controlled.

Further, the battery 41 supplies a voltage of 3V or more to the power conversion module 42 for boosting, reducing, stabilizing, and the like. And then supplies power to the wireless positioning module 3 and the liquid level sensing module 1.

Specifically, the battery 41 adopts a lithium subcell or a dry cell or a lithium manganese cell (4G-CAT1 and a larger current).

The power supply mode of the power module 4 is as follows: when the liquid level sensing module 1 does not work, the wireless liquid level locator is in a dormant state, and the power conversion module 42 provides normal power to the wireless locating module 3 so as to wake up (timed wake-up and remote wake-up) when the liquid level sensing module needs to work. The awakening process is that after receiving the awakening instruction, the information receiving device 31 in the wireless positioning module 3 sends a level to the power control module 43 in the power module 4 through the I/O port, and then the power control module 43 is turned on to send working current to the wireless positioning module 3 and the liquid level sensing module 1. The wireless liquid level locator works.

This wireless liquid level locator 100 still includes waterproof case 6, liquid level sensing module 1 wireless orientation module 3 and power module 4 all accomodate in waterproof case 6 is interior, and in order to improve explosion-proof requirement, this waterproof case 6 still can adopt fire-retardant material to make.

While the embodiments of the invention have been disclosed above, it is not limited to the applications set forth in the description and embodiments, but is capable of being applied in all kinds of fields adapted to the invention, and further modifications may readily be made by those skilled in the art, and the invention is therefore not limited to the details shown and described herein, without departing from the general concept defined by the claims and their equivalents.
