[0029] 1. MT1 does not transmit; SR1 does not receive the signal and therefore outputs a high potential. After being transmitted to ST1 in the third bidirectional transceiver switch S1 by the first manual switch K9 and the first high liquid level switch K5, ST1 will not transmit either, and MR1 does not receive and keeps the output at a high potential; this high potential is then transmitted to MT1 via switch K20 to keep the circuit in its original state.

[0030] 2. MT1 transmits UHF signal, SR1 outputs low potential after receiving it, and transmits it to ST1 of the third two-way transceiver switch S1 through the first manual switch K9 and the first high liquid level switch K5. ST1 transmits UHF signal after receiving it, which is received by MR1.

[0033] 1. MT2 does not transmit; SR2 does not receive the signal and therefore outputs a high potential. After being transmitted to ST2 in the fourth bidirectional transceiver switch S2 by the second manual switch K10 and the second high liquid level switch K6, ST2 will not transmit either, and MR2 does not receive and keeps the output at a high potential; this high potential is then transmitted to MT2 via switch K20 to keep the circuit in its original state. This constitutes a closed-loop path state formed by wired and wireless, which will remain in place without external triggering. This state is hereinafter referred to as the unlocked state;

[0034] Second, MT2 transmits UHF signal, SR2 outputs low potential after receiving it, and transmits it to ST2 of the fourth bidirectional transceiver switch S2 through the second manual switch K10 and the second high liquid level switch K6. ST2 transmits UHF signal after receiving it, which is received by MR2. The low potential outputted by ST2 is transmitted to MT2 through switch K20 as its control signal, so that it continues to transmit UHF signal. In this way, the closed-loop path state formed by wired and wireless will be maintained in the absence of external triggering. This state is hereinafter referred to as the locked state.

[0035] The first indicator light L11 is connected to the main storage tank end module circuit, and the first indicator light L11 is lit in the locked state. The resistor R21 is connected to the circuit, which will serve as a potential pull-up resistor at the input end of MT1 to maintain the circuit in the unlocked state.
