Embodiment 1

[0037] like figure 1 As shown, the query module 1 in the present invention is responsible for sending a query command to each sub-control board connected to the main control board, and the sub-control board packs the relevant data to form a data packet after receiving the query command, and returns the data packet. To the main control board, the receiving module 2 is responsible for receiving the returned data packet and sending the data packet to the parsing module 3. The parsing module 3 parses the received data packet and parses out the refueling vehicle number information contained in the data packet. , gas filling volume information, status information and number information of the sub-control board, and then enter the data processing operation; the processing module 4 judges the number of data packets with the same gas filling vehicle number information according to the information parsed by the analysis module 3, if the number of data packets When ≥ 2, add the refilling...

Embodiment 2

[0046] The difference between this embodiment and the first embodiment is that the sub-control board numbers in the query command are sent in order from large to small, that is, the sending starts from the last board (i=N), and after the last board is sent, it is sent one by one. Decrease 1 (n=i-1) and send it to other sub-control boards; when n<1, start a new round of sending query commands from the last board. The rest are the same as in Example 1.

[0047] The query commands in the above-mentioned embodiments are all sent one by one in the sequence of the numbers of the sub-control boards, and of course they can also be sent in the form of broadcasting, that is, the sub-control boards only receive the query commands related to themselves.

Abstract

The invention discloses a multigun gas dispenser cumulative display method and system, and belongs to the technical field of gas or liquid distribution and measurement, and the multigun gas dispenser cumulative display system comprises a query module, a receiving module, an analysis module, a processing module, a display module and a storage module. According to the multigun gas dispenser cumulative display method and system, a main control board can automatically, according to gas dispenser car number information, selects sub control boards simultaneously dispensing a gas to the same car from a plurality of sub control boards which are governed by the main control board, gas dispensing amount data of the selected sub control boards is summed and displayed, the gas dispensing amount and money amount of the car can be updated and displayed in real time in a display screen connected with the main control board, the gas dispensing condition is clear like the condition when a user uses a same gas dispensing gun for dispensing the gas, the wrong artificial calculation phenomenon can be avoided, calculation time is saved, and the gas dispensing efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of gas or liquid distribution and metering, and in particular relates to a method and system for accumulative display of a multi-gun gas dispenser. Background technique [0002] With the increasing shortage of oil resources, its price is also rising day by day, as a clean energy, natural gas is gradually becoming a new type of fuel for vehicles to ease the supply pressure of oil resources. As a result, the gas dispenser came into being as a kind of gas filling equipment. The usual refilling machine is like a refueling machine, with one refilling gun on one side, and one refilling gun can only refill one vehicle at the same time. This kind of refilling machine is gradually leaking in practical applications, especially for vehicles with three When a large vehicle with more than one gas storage tank is filled with gas, each gas storage tank needs to be filled one by one, which prolongs the filling time and red...
