Abstract
The utility model discloses the multi-gun gas dispenser of a kind of energy communication, belong to distribution and the field of measuring techniques of gas or liquid, it comprises the air filling gun of more than two, often prop up air filling gun and be equipped with sub-control plate separately, it is characterized in that: also comprise master control borad, master control borad installs a RS232 communication port, the 2nd RS232 communication port installed by sub-control plate, be attempted by the receiving terminal of a RS232 communication port after the transmitting terminal series diode of the 2nd RS232 communication port, the anode of each diode connects the receiving terminal of a RS232 communication port.This kind of multi-gun gas dispenser same time only has a sub-control plate to send signal, its transmitting terminal presents low level, the transmitting terminal not sending the sub-control plate of signal is high level state, coupled diode can not arrive conducting, so the signal that sub-control plate sends can only be received by the receiving terminal of master control borad, and the transmitting terminal of other sub-control plate can not be arrived, avoid communication confusion and interference.
Description
Technical field
The utility model belongs to distribution and the field of measuring techniques of gas or liquid, is specifically related to the multi-gun gas dispenser of a kind of energy communication.
Background technique
Along with the worsening shortages of petroleum resources, its price also rises day by day, and rock gas is progressively becoming a kind of Novel vehicle fuel as a kind of clean energy resource, to alleviate the supply pressure of petroleum resources.So filling machine arises at the historic moment as a kind of aerating equipment.Common filling machine is as oilling machine, an one side air filling gun, an air filling gun can only be a car aerating simultaneously, this kind of filling machine also spills deficiency in actual applications gradually cruelly, especially to when there is the large vehicle aerating of more than three gas holder, need the aerating one by one of each gas holder, extend the aerating time, reduce aerating efficiency.
For the problems referred to above, people have developed multi-gun gas dispenser successively, and each air filling gun has and independently shows with print system separately and work alone.So, more than two air filling guns are after a car aerating terminates simultaneously, need manually the amount of money of each air filling gun to be done accumulation settlement.This kind of mode is both time-consuming takes a lot of work, and there is again the hidden danger of artificial mistake in computation.
So people want to develop a multi-gun gas dispenser that can carry out accumulation settlement to each air filling gun of same vehicle aerating.Wherein, the communication between master control borad and each sub-control plate can be realized, and the data that sub-control plate sends can only be received by master control borad, and can not to be received by other sub-control plate be the key point realizing accumulative display.
Summary of the invention
Technical problem to be solved in the utility model is to provide the multi-gun gas dispenser of a kind of energy communication, can ensure that the data that sub-control plate sends only are received by master control borad.
For solving the problems of the technologies described above, the technical solution of the utility model is: the multi-gun gas dispenser designing the communication of a kind of energy, comprise the air filling gun of more than two, often prop up air filling gun and be equipped with sub-control plate separately, it is characterized in that: also comprise master control borad, master control borad installs a RS232 communication port, the 2nd RS232 communication port installed by sub-control plate, be attempted by the receiving terminal of a RS232 communication port after the transmitting terminal series diode of the 2nd RS232 communication port, the anode of each diode connects the receiving terminal of a RS232 communication port.
Compared with prior art, the beneficial effects of the utility model are:
1, the receiving terminal of a RS232 communication port is connected to after transmitting terminal series diode due to the 2nd RS232 communication port, and the anode of each diode connects the receiving terminal of a RS232 communication port, and diode has unilateral conduction, the same time only has a sub-control plate to send signal, its transmitting terminal presents low level, the transmitting terminal not sending the sub-control plate of signal is high level state, coupled diode can not arrive conducting, so the signal that sub-control plate sends can only be received by the receiving terminal of master control borad, and the transmitting terminal of other sub-control plate can not be arrived, avoid communication confusion, indispensable communication prerequisite is established for multi-gun gas dispenser realizes accumulative display.
2, the utility model structure is simple, and automatic accumulation settlement when the multiple air filling guns for multi-gun gas dispenser are same car aerating is significant, is convenient in industry apply.
Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present utility model.
Mark in figure: 1, master control borad; 2, sub-control plate; 3, the 2nd RS232 communication port; 4, a RS232 communication port.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
The utility model is described to have three air filling guns.With as shown in Figure 1, be provided with one piece of master control borad 1 and three air filling guns in the utility model, often prop up air filling gun and be equipped with sub-control plate 2 separately, the 2nd RS232 communication port 3 installed by sub-control plate 2; Master control borad 1 installs a RS232 communication port 4, the receiving terminal Rx of a RS232 communication port 4 is connected to after the transmitting terminal Tx series diode D of the 2nd RS232 communication port 3, three diode D are all the receiving terminal Rx connecting a RS232 communication port 4 with anode, the receiving terminal Rx of the 2nd RS232 communication port 3 is connected on the transmitting terminal Tx of a RS232 communication port 4, and the ground end END of the 2nd RS232 communication port 3 is corresponding with the ground end END of a RS232 communication port 4 to be connected.
During use, often prop up air filling gun before aerating operation, all need in the sub-control plate 2 that is equipped with separately of the license plate number of aerating vehicle input air filling gun, air filling gun is in the process of aerating, and it adds after tolerance all has respective measuring apparatus metering and sends in the sub-control plate 2 of oneself.When branched air filling gun is same car aerating jointly, the automatic accumulating function of master control borad 1 be realized, need master control borad 1 first by the digital independent of each sub-control plate 2 out.At this moment, sub-control plate 2 needs to send the data to master control borad 1, the same time only has a sub-control plate 2 to send signal, its the 2nd RS232 communication port 3 transmitting terminal Tx presents low level, and the transmitting terminal Tx not sending the sub-control plate 2 of signal is high level state, utilizes diode D to have the characteristic of unilateral conduction, coupled diode D can not arrive conducting, so the signal that sub-control plate 2 sends can only be received by master control borad 1, and other sub-control plate 2 can not be arrived, avoid communication confusion and interference.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
